The transtheoretical model of behavior change is an integrative theory of therapy that assesses an individual's readiness to act on a new healthier behavior, and provides strategies, or processes of change to guide the individual.The model is composed of constructs such as: stages of change, processes of change, levels of change, self-efficacy, and decisional balance.
Behavioural change theories are attempts to explain why behaviours change. These theories cite environmental, personal, and behavioural characteristics as the major factors in behavioural determination. In recent years, there has been increased interest in the application of these theories in the areas of health, education, criminology, energy and international development with the hope that understanding behavioural change will improve the services offered in these areas. Some scholars have recently introduced a distinction between models of behavior and theories of change. Whereas models of behavior are more diagnostic and geared towards understanding the psychological factors that explain or predict a specific behavior, theories of change are more process-oriented and generally aimed at changing a given behavior. Thus, from this perspective, understanding and changing behavior are two separate but complementary lines of scientific investigation.
Integrative psychotherapy is the integration of elements from different schools of psychotherapy in the treatment of a client. Integrative psychotherapy may also refer to the psychotherapeutic process of integrating the personality: uniting the "affective, cognitive, behavioral, and physiological systems within a person".
Self-efficacy is an individual's belief in their innate ability to achieve goals. Albert Bandura defines it as a personal judgment of "how well one can execute courses of action required to deal with prospective situations". Expectations of self-efficacy determine whether an individual will be able to exhibit coping behavior and how long effort will be sustained in the face of obstacles. Individuals who have high self-efficacy will exert sufficient effort that, if well executed, leads to successful outcomes, whereas those with low self-efficacy are likely to cease effort early and fail. Psychologists have studied self-efficacy from several perspectives, noting various paths in the development of self-efficacy; the dynamics of self-efficacy, and lack thereof, in many different settings; interactions between self-efficacy and self-concept; and habits of attribution that contribute to, or detract from, self-efficacy. Kathy Kolbe adds, "Belief in innate abilities means valuing one's particular set of conative strengths. It also involves determination and perseverance to overcome obstacles that would interfere with utilizing those innate abilities to achieve goals."
The transtheoretical model is also known by the abbreviation "TTM"and sometimes by the term "stages of change", although this latter term is a synecdoche since the stages of change are only one part of the model along with processes of change, levels of change, etc. Several self-help books—Changing for Good (1994), Changeology (2012), and Changing to Thrive (2016) —and articles in the news media have discussed the model. It has been called "arguably the dominant model of health behaviour change, having received unprecedented research attention, yet it has simultaneously attracted criticism".
A synecdoche is a figure of speech in which a term for a part of something refers to the whole of something or vice versa. A synecdoche is a class of metonymy, often by means of either mentioning a part for the whole or conversely the whole for one of its parts. Examples from common English expressions include "suits", "boots", and "America".
A self-help book is one that is written with the intention to instruct its readers on solving personal problems. The books take their name from Self-Help, an 1859 best-seller by Samuel Smiles, but are also known and classified under "self-improvement", a term that is a modernized version of self-help. Self-help books moved from a niche position to being a postmodern cultural phenomenon in the late twentieth century.
The news media or news industry are forms of mass media that focus on delivering news to the general public or a target public. These include print media, broadcast news, and more recently the Internet.
James O. Prochaska of the University of Rhode Island, and Carlo Di Clemente and colleagues developed the transtheoretical model beginning in 1977.It is based on analysis and use of different theories of psychotherapy, hence the name "transtheoretical".
James O. Prochaska is a Professor of Psychology and Director of the Cancer Prevention Research Center at the University of Rhode Island He is the lead developer of the Transtheoretical Model of Behavior Change (TTM) beginning in 1983. Prochaska earned his B.A. in Psychology at Wayne State University in 1964, followed by his M.A. (1967) and Ph.D. Degrees (1969) both at Wayne State University. He is the author or co-author of over 400 publications on the dynamics of behavioral change - most of which expand the theory, test the TTM in randomized controlled trials, and defend the TTM.
The University of Rhode Island, commonly referred to as URI, is the flagship public research as well as the land grant and sea grant university for the state of Rhode Island. Its main campus is located in the village of Kingston in southern Rhode Island. Additionally, smaller campuses include the Feinstein Campus in Providence, the Rhode Island Nursing Education Center in Providence, the Narragansett Bay Campus in Narragansett, and the W. Alton Jones Campus in West Greenwich.
Prochaska and colleagues refined the model on the basis of research that they published in peer-reviewed journals and books.
This construct refers to the temporal dimension of behavioural change. In the transtheoretical model, change is a "process involving progress through a series of stages":
In addition, the researchers conceptualized "Relapse" (recycling) which is not a stage in itself but rather the "return from Action or Maintenance to an earlier stage".
The quantitative definition of the stages of change (see below) is perhaps the most notorious feature of the model. However it is also one of the most critiqued, even in the field of smoking cessation, where it was originally formulated. It has been said that such quantitative definition (i.e. a person is in preparation if it intends to change within a month) does not reflect the nature of behaviour change, that it does not have better predictive power than simpler questions (i.e. "do you have plans to change..."), and that it has problems regarding its classification reliability.
Communication theorist and sociologist Everett Rogers suggested that the stages of change are analogues of the stages of the innovation adoption process in Rogers' theory of diffusion of innovations.
|Standard time||more than 6 months||in the next 6 months||in the next month||now||at least 6 months||any time|
Stage 1: Precontemplation (not ready)
People at this stage do not intend to start the healthy behavior in the near future (within 6 months), and may be unaware of the need to change. People here learn more about healthy behavior: they are encouraged to think about the pros of changing their behavior and to feel emotions about the effects of their negative behavior on others.
Precontemplators typically underestimate the pros of changing, overestimate the cons, and often are not aware of making such mistakes.
One of the most effective steps that others can help with at this stage is to encourage them to become more mindful of their decision making and more conscious of the multiple benefits of changing an unhealthy behavior.
Stage 2: Contemplation (getting ready)
At this stage, participants are intending to start the healthy behavior within the next 6 months. While they are usually now more aware of the pros of changing, their cons are about equal to their Pros. This ambivalence about changing can cause them to keep putting off taking action.
People here learn about the kind of person they could be if they changed their behavior and learn more from people who behave in healthy ways.
Others can influence and help effectively at this stage by encouraging them to work at reducing the cons of changing their behavior.
Stage 3: Preparation (ready)
People at this stage are ready to start taking action within the next 30 days. They take small steps that they believe can help them make the healthy behavior a part of their lives. For example, they tell their friends and family that they want to change their behavior.
People in this stage should be encouraged to seek support from friends they trust, tell people about their plan to change the way they act, and think about how they would feel if they behaved in a healthier way. Their number one concern is: when they act, will they fail? They learn that the better prepared they are, the more likely they are to keep progressing.
Stage 4: Action (current action)
People at this stage have changed their behavior within the last 6 months and need to work hard to keep moving ahead. These participants need to learn how to strengthen their commitments to change and to fight urges to slip back.
People in this stage progress by being taught techniques for keeping up their commitments such as substituting activities related to the unhealthy behavior with positive ones, rewarding themselves for taking steps toward changing, and avoiding people and situations that tempt them to behave in unhealthy ways.
Stage 5: Maintenance (monitoring)
People at this stage changed their behavior more than 6 months ago. It is important for people in this stage to be aware of situations that may tempt them to slip back into doing the unhealthy behavior—particularly stressful situations.
It is recommended that people in this stage seek support from and talk with people whom they trust, spend time with people who behave in healthy ways, and remember to engage in healthy activities to cope with stress instead of relying on unhealthy behavior.
Relapse in the TTM specifically applies to individuals who successfully quit smoking or using drugs or alcohol, only to resume these unhealthy behaviors. Individuals who attempt to quit highly addictive behaviors such as drug, alcohol, and tobacco use are at particularly high risk of a relapse. Achieving a long-term behavior change often requires ongoing support from family members, a health coach, a physician, or another motivational source. Supportive literature and other resources can also be helpful to avoid a relapse from happening.
The 10 processes of change are "covert and overt activities that people use to progress through the stages".
To progress through the early stages, people apply cognitive, affective, and evaluative processes. As people move toward Action and Maintenance, they rely more on commitments, conditioning, contingencies, environmental controls, and support.
Prochaska and colleagues state that their research related to the transtheoretical model shows that interventions to change behavior are more effective if they are "stage-matched", that is, "matched to each individual's stage of change".
In general, for people to progress they need:
The ten processes of change include:
Health researchers have extended Prochaska's and DiClemente's 10 original processes of change by an additional 21 processes. In the first edition of Planning Health Promotion Programs,Bartholomew et al. (2006) summarised the processes that they identified in a number of studies; however, their extended list of processes was removed from later editions of the text. The additional processes of Bartholomew et al. were:
While most of these processes are associated with health interventions such as smoking cessation and other addictive behaviour,some of them are also used in travel interventions. Depending on the target behaviour the effectiveness of the process should differ. Also some processes are recommended in a specific stage, while others can be used in one or more stages. Recently, these processes have been identified in travel interventions, broadening the scope of TTM in other research domains.
This core construct "reflects the individual's relative weighing of the pros and cons of changing".Decision making was conceptualized by Janis and Mann as a "decisional balance sheet" of comparative potential gains and losses. Decisional balance measures, the pros and the cons, have become critical constructs in the transtheoretical model. The pros and cons combine to form a decisional "balance sheet" of comparative potential gains and losses. The balance between the pros and cons varies depending on which stage of change the individual is in.
Sound decision making requires the consideration of the potential benefits (pros) and costs (cons) associated with a behavior's consequences. TTM research has found the following relationships between the pros, cons, and the stage of change across 48 behaviors and over 100 populations studied.
The evaluation of pros and cons is part of the formation of attitudes. Attitude is defined as a "psychological tendency that is expressed by evaluating a particular entity with some degree of favour or disfavour".This means that by evaluating pros and cons we form a positive or negative attitude about something or someone. During the change process individuals gradually shift from cons to pros, forming a more positive attitude towards the target behaviour. Attitudes are one of the core constructs explaining behaviour and behaviour change in various research domains. Other behaviour models, such as the theory of planned behavior (TPB) and the stage model of self-regulated change, also emphasise attitude as an important determinant of behaviour. The progression through the different stages of change is reflected in a gradual change in attitude before the individual acts. Most of the processes of change aim at evaluating and reevaluating as well as reinforcing specific elements of the current and target behaviour. The processes of change contribute to a great degree on attitude formation.
Due to the synonymous use of decisional balance and attitude, travel behaviour researchers have begun to combine the TTM with the TPB. Forwarduses the TPB variables to better differentiate the different stages. Especially all TPB variables (attitude, perceived behaviour control, descriptive and subjective norm) are positively show a gradually increasing relationship to stage of change for bike commuting. As expected, intention or willingness to perform the behaviour increases by stage. Similarly, Bamberg uses various behavior models, including the transtheoretical model, theory of planned behavior and norm-activation model, to build the stage model of self-regulated behavior change (SSBC). Bamberg claims that his model is a solution to criticism raised towards the TTM. Some researchers in travel, dietary, and environmental research have conducted empirical studies, showing that the SSBC might be a future path for TTM-based research.
This core construct is "the situation-specific confidence people have that they can cope with high-risk situations without relapsing to their unhealthy or high risk-habit".The construct is based on Bandura's self-efficacy theory and conceptualizes a person's perceived ability to perform on a task as a mediator of performance on future tasks. In his research Bandura already established that greater levels of perceived self-efficacy leads to greater changes in behavior. Similarly, Ajzen mentions the similarity between the concepts of self-efficacy and perceived behavioral control. This underlines the integrative nature of the transtheoretical model which combines various behavior theories. A change in the level of self-efficacy can predict a lasting change in behavior if there are adequate incentives and skills. The transtheoretical model employs an overall confidence score to assess an individual's self-efficacy. Situational temptations assess how tempted people are to engage in a problem behavior in a certain situation.
This core construct identifies the depth or complexity of presenting problems according to five levels of increasing complexity.Different therapeutic approaches are recommended for each level as well as for each stage of change. The levels are:
The outcomes of the TTM computerized tailored interventions administered to participants in pre-Action stages are outlined below.
A national sample of pre-Action adults was provided a stress management intervention. At the 18-month follow-up, a significantly larger proportion of the treatment group (62%) was effectively managing their stress when compared to the control group. The intervention also produced statistically significant reductions in stress and depression and an increase in the use of stress management techniques when compared to the control group.Two additional clinical trials of TTM programs by Prochaska et al. and Jordan et al. also found significantly larger proportions of treatment groups effectively managing stress when compared to control groups.
Over 1,000 members of a New England group practice who were prescribed antihypertensive medication participated in an adherence to antihypertensive medication intervention. The vast majority (73%) of the intervention group who were previously pre-Action were adhering to their prescribed medication regimen at the 12-month follow-up when compared to the control group.
Members of a large New England health plan and various employer groups who were prescribed a cholesterol lowering medication participated in an adherence to lipid-lowering drugs intervention. More than half of the intervention group (56%) who were previously pre-Action were adhering to their prescribed medication regimen at the 18-month follow-up. Additionally, only 15% of those in the intervention group who were already in Action or Maintenance relapsed into poor medication adherence compared to 45% of the controls. Further, participants who were at risk for physical activity and unhealthy diet were given only stage-based guidance. The treatment group doubled the control group in the percentage in Action or Maintenance at 18 months for physical activity (43%) and diet (25%).
Participants were 350 primary care patients experiencing at least mild depression but not involved in treatment or planning to seek treatment for depression in the next 30 days. Patients receiving the TTM intervention experienced significantly greater symptom reduction during the 9-month follow-up period. The intervention's largest effects were observed among patients with moderate or severe depression, and who were in the Precontemplation or Contemplation stage of change at baseline. For example, among patients in the Precontemplation or Contemplation stage, rates of reliable and clinically significant improvement in depression were 40% for treatment and 9% for control. Among patients with mild depression, or who were in the Action or Maintenance stage at baseline, the intervention helped prevent disease progression to Major Depression during the follow-up period.
Fifty-hundred-and-seventy-seven overweight or moderately obese adults (BMI 25-39.9) were recruited nationally, primarily from large employers. Those randomly assigned to the treatment group received a stage-matched multiple behavior change guide and a series of tailored, individualized interventions for three health behaviors that are crucial to effective weight management: healthy eating (i.e., reducing calorie and dietary fat intake), moderate exercise, and managing emotional distress without eating. Up to three tailored reports (one per behavior) were delivered based on assessments conducted at four time points: baseline, 3, 6, and 9 months. All participants were followed up at 6, 12, and 24 months. Multiple Imputation was used to estimate missing data. Generalized Labor Estimating Equations (GLEE) were then used to examine differences between the treatment and comparison groups. At 24 months, those who were in a pre-Action stage for healthy eating at baseline and received treatment were significantly more likely to have reached Protons or Maintenance than the comparison group (47.5% vs. 34.3%). The intervention also impacted a related, but untreated behavior: fruit and vegetable consumption. Over 48% of those in the treatment group in a pre-Action stage at baseline progressed to Action or Maintenance for eating at least 5 servings a day of fruit and vegetables as opposed to 39% of the comparison group. Individuals in the treatment group who were in a pre-Action stage for exercise at baseline were also significantly more likely to reach Action or Maintenance (44.9% vs. 38.1%). The treatment also had a significant effect on managing emotional distress without eating, with 49.7% of those in a pre-Action stage at baseline moving to Action or Maintenance versus 30.3% of the comparison group. The groups differed on weight lost at 24 months among those in a pre-action stage for healthy eating and exercise at baseline. Among those in a pre-Action stage for both healthy eating and exercise at baseline, 30% of those randomized to the treatment group lost 5% or more of their body weight vs.18.6% in the comparison group. Coaction of behavior change occurred and was much more pronounced in the treatment group with the treatment group losing significantly more than the comparison group. This study demonstrates the ability of TTM-based tailored feedback to improve healthy eating, exercise, managing emotional distress, and weight on a population basis. The treatment produced the highest population impact to date on multiple health risk behaviors.
Multiple studies have found individualized interventions tailored on the 14 TTM variables for smoking cessation to effectively recruit and retain pre-Action participants and produce long-term abstinence rates within the range of 22% – 26%. These interventions have also consistently outperformed alternative interventions including best-in-class action-oriented self-help programs,non-interactive manual-based programs, and other common interventions. Furthermore, these interventions continued to move pre-Action participants to abstinence even after the program ended. For a summary of smoking cessation clinical outcomes, see Velicer, Redding, Sun, & Prochaska, 2007 and Jordan, Evers, Spira, King & Lid, 2013.
In the treatment of smoke control, TTM focuses on each stage to monitor and to achieve a progression to the next stage.
|Stage||Precontemplation||Contemplation||Preparation||Action||Maintenance||Can Relapse to an|
|Standard time||more than 6 months||in the next 6 months||in the next month||now||at least 6 months||any time|
|Action and intervention||not ready to quit or demoralized||ambivalent||intend to quit||take action and quit||sustained||back to smoke|
|Related source||Book, newspaper, friend||Book, newspaper, friend||doctor, nurse, friend...||doctor, nurse, friend...||friend, family||temptation, stress, distress|
In each stage, a patient may have multiple sources that could influence their behavior. These may include: friends, books, and interactions with their healthcare providers. These factors could potentially influence how successful a patient may be in moving through the different stages. This stresses the importance to have continuous monitoring and efforts to maintain progress at each stage. TTM helps guide the treatment process at each stage, and may assist the healthcare provider in making an optimal therapeutic decision.
The use of TTM in travel behaviour interventions is rather novel. A number of cross-sectional studies investigated the individual constructs of TTM, e.g. stage of change, decisional balance and self-efficacy, with regards to transport mode choice. The cross-sectional studies identified both motivators and barriers at the different stages regarding biking, walking and public transport.The motivators identified were e.g. liking to bike/walk, avoiding congestion and improved fitness. Perceived barriers were e.g. personal fitness, time and the weather. This knowledge was used to design interventions that would address attitudes and misconceptions to encourage an increased use of bikes and walking. These interventions aim at changing people's travel behaviour towards more sustainable and more active transport modes. In health-related studies, TTM is used to help people walk or bike more instead of using the car. Most intervention studies aim to reduce car trips for commute to achieve the minimum recommended physical activity levels of 30 minutes per day. Other intervention studies using TTM aim to encourage sustainable behaviour. By reducing single occupied motor vehicle and replacing them with so called sustainable transport (public transport, car pooling, biking or walking), greenhouse gas emissions can be reduced considerably. A reduction in the number of cars on our roads solves other problems such as congestion, traffic noise and traffic accidents. By combining health and environment related purposes, the message becomes stronger. Additionally, by emphasising personal health, physical activity or even direct economic impact, people see a direct result from their changed behaviour, while saving the environment is a more general and effects are not directly noticeable.
Different outcome measures were used to assess the effectiveness of the intervention. Health-centred intervention studies measured BMI, weight, waist circumference as well as general health. However, only one of three found a significant change in general health, while BMI and other measures had no effect.Measures that are associated with both health and sustainability were more common. Effects were reported as number of car trips, distance travelled, main mode share etc. Results varied due to greatly differing approaches. In general, car use could be reduced between 6% and 55%, while use of the alternative mode (walking, biking and/or public transport) increased between 11% and 150%. These results indicate a shift to action or maintenance stage, some researchers investigated attitude shifts such as the willingness to change. Attitudes towards using alternative modes improved with approximately 20% to 70%. Many of the intervention studies did not clearly differentiate between the five stages, but categorised participants in pre-action and action stage. This approach makes it difficult to assess the effects per stage. Also, interventions included different processes of change; in many cases these processes are not matched to the recommended stage. It highlights the need to develop a standardised approach for travel intervention design. Identifying and assessing which processes are most effective in the context of travel behaviour change should be a priority in the future in order to secure the role of TTM in travel behaviour research.
The TTM has been called "arguably the dominant model of health behaviour change, having received unprecedented research attention, yet it has simultaneously attracted criticism".Depending on the field of application (e.g. smoking cessation, substance abuse, condom use, diabetes treatment, obesity and travel) somewhat different criticisms have been raised.
In a systematic review, published in 2003, of 23 randomized controlled trials, the authors found that "stage based interventions are no more effective than non-stage based interventions or no intervention in changing smoking behaviour.However, it was also mentioned that stage based interventions are often used and implemented inadequately in practice. Thus, criticism is directed towards the use rather the effectiveness of the model itself. Looking at interventions targeting smoking cessation in pregnancy found that stage-matched interventions were more effective than non-matched interventions. One reason for this was the greater intensity of stage-matched interventions. Also, the use of stage-based interventions for smoking cessation in mental illness proved to be effective. Further studies, e.g. a randomized controlled trial published in 2009, found no evidence that a TTM based smoking cessation intervention was more effective than a control intervention not tailored to stage of change. The study claims that those not wanting to change (i.e. precontemplators) tend to be responsive to neither stage nor non-stage based interventions. Since stage-based interventions tend to be more intensive they appear to be most effective at targeting contemplators and above rather than pre-contemplators. A 2010 systematic review of smoking cessation studies under the auspices of the Cochrane Collaboration found that "stage-based self-help interventions (expert systems and/or tailored materials) and individual counselling were neither more nor less effective than their non-stage-based equivalents.
Main criticism is raised regarding the "arbitrary dividing lines" that are drawn between the stages. West claimed that a more coherent and distinguishable definition for the stages is needed.Especially the fact that the stages are bound to a specific time interval is perceived to be misleading. Additionally, the effectiveness of stage-based interventions differs depending on the behavior. A continuous version of the model has been proposed, where each process is first increasingly used, and then decreases in importance, as smokers make progress along some latent dimension. This proposal suggests the use of processes without reference to stages of change.
The model "assumes that individuals typically make coherent and stable plans", when in fact they often do not.
Within research on prevention of pregnancy and sexually transmitted diseases a systematic review from 2003 comes to the conclusion that "no strong conclusions" can be drawn about the effectiveness of interventions based on the transtheoretical model.Again this conclusion is reached due to the inconsistency of use and implementation of the model. This study also confirms that the better stage-matched the intervention the more effect it has to encourage condom use.
Within the health research domain, a 2005 systematic review of 37 randomized controlled trials claims that "there was limited evidence for the effectiveness of stage-based interventions as a basis for behavior change.Studies with which focused on increasing physical activity levels through active commute however showed that stage-matched interventions tended to have slightly more effect than non-stage matched interventions. Since many studies do not use all constructs of the TTM, additional research suggested that the effectiveness of interventions increases the better it is tailored on all core constructs of the TTM in addition to stage of change. In diabetes research the "existing data are insufficient for drawing conclusions on the benefits of the transtheoretical model" as related to dietary interventions. Again, studies with slightly different design, e.g. using different processes, proved to be effective in predicting the stage transition of intention to exercise in relation to treating patients with diabetes.
TTM has generally found a greater popularity regarding research on physical activity, due to the increasing problems associated with unhealthy diets and sedentary living, e.g. obesity, cardiovascular problems.A 2011 Cochrane Systematic Review found that there is little evidence to suggest that using the Transtheoretical Model Stages of Change (TTM SOC) method is effective in helping obese and overweight people lose weight. Earlier in a 2009 paper, the TTM was considered to be useful in promoting physical activity. In this study, the algorithms and questionnaires that researchers used to assign people to stages of change lacked standardisation to be compared empirically, or validated.
Similar criticism regarding the standardisation as well as consistency in the use of TTM is also raised in a recent review on travel interventions.With regard to travel interventions only stages of change and sometimes decisional balance constructs are included. The processes used to build the intervention are rarely stage-matched and short cuts are taken by classifying participants in a pre-action stage, which summarises the precontemplation, contemplation and preparation stage, and an action/maintenance stage. More generally, TTM has been criticised within various domains due to the limitations in the research designs. For example, many studies supporting the model have been cross-sectional, but longitudinal study data would allow for stronger causal inferences. Another point of criticism is raised in a 2002 review, where the model's stages were characterized as "not mutually exclusive". Furthermore, there was "scant evidence of sequential movement through discrete stages". While research suggests that movement through the stages of change is not always linear, a study conducted in 1996 demonstrated that the probability of forward stage movement is greater than the probability of backward stage movement. Due to the variations in use, implementation and type of research designs, data confirming TTM are ambiguous. More care has to be taken in using a sufficient amount of constructs, trustworthy measures, and longitudinal data.
Smoking cessation is the process of discontinuing tobacco smoking. Tobacco smoke contains nicotine, which is addictive and can cause dependence. Nicotine withdrawal makes the process of quitting often difficult.
Health psychology is the study of psychological and behavioral processes in health, illness, and healthcare. It is concerned with understanding how psychological, behavioral, and cultural factors contribute to physical health and illness. Psychological factors can affect health directly. For example, chronically occurring environmental stressors affecting the hypothalamic–pituitary–adrenal axis, cumulatively, can harm health. Behavioral factors can also affect a person's health. For example, certain behaviors can, over time, harm or enhance health. Health psychologists take a biopsychosocial approach. In other words, health psychologists understand health to be the product not only of biological processes but also of psychological, behavioral, and social processes.
Behavior change, in the context of public health, refers to efforts to change people's personal habits to prevent disease. Behavior change in public health is also known as social and behavior change communication (SBCC). More and more, efforts focus on prevention of disease to save healthcare care costs. This is particularly important in low and middle income countries, where health interventions have come under increased scrutiny because of the cost.
In psychology, the theory of planned behavior is a theory that links one's beliefs and behavior.
Motivational therapy is a combination of humanistic treatment and enhanced cognitive-behavioral strategies, designed to treat substance abuse. It is similar to motivational interviewing and motivational enhancement therapy.
Social cognitive theory (SCT), used in psychology, education, and communication, holds that portions of an individual's knowledge acquisition can be directly related to observing others within the context of social interactions, experiences, and outside media influences. This theory was advanced by Albert Bandura as an extension of his social learning theory. The theory states that when people observe a model performing a behavior and the consequences of that behavior, they remember the sequence of events and use this information to guide subsequent behaviors. Observing a model can also prompt the viewer to engage in behavior they already learned. In other words, people do not learn new behaviors solely by trying them and either succeeding or failing, but rather, the survival of humanity is dependent upon the replication of the actions of others. Depending on whether people are rewarded or punished for their behavior and the outcome of the behavior, the observer may choose to replicate behavior modeled. Media provides models for a vast array of people in many different environmental settings.
Multitheoretical psychotherapy (MTP) is a new approach to integrative psychotherapy developed by Jeff E. Brooks-Harris and his colleagues at the University of Hawaii at Manoa. MTP is organized around five principles for integration:
The health belief model (HBM) is a psychological health behavior change model developed to explain and predict health-related behaviors, particularly in regard to the uptake of health services. The health belief model was developed in the 1950s by social psychologists at the U.S. Public Health Service and remains one of the best known and most widely used theories in health behavior research. The health belief model suggests that people's beliefs about health problems, perceived benefits of action and barriers to action, and self-efficacy explain engagement in health-promoting behavior. A stimulus, or cue to action, must also be present in order to trigger the health-promoting behavior.
Culture change is a term used in public policy making that emphasizes the influence of cultural capital on individual and community behavior. It has been sometimes called repositioning of culture, which means the reconstruction of the cultural concept of a society. It places stress on the social and cultural capital determinants of decision making and the manner in which these interact with other factors like the availability of information or the financial incentives facing individuals to drive behavior.
Chronic care management encompasses the oversight and education activities conducted by health care professionals to help patients with chronic diseases and health conditions such as diabetes, high blood pressure, lupus, multiple sclerosis and sleep apnea learn to understand their condition and live successfully with it. This term is equivalent to disease management for chronic conditions. The work involves motivating patients to persist in necessary therapies and interventions and helping them to achieve an ongoing, reasonable quality of life.
Fear appeal is a term used in psychology, sociology and marketing. It generally describes a strategy for motivating people to take a particular action, endorse a particular policy, or buy a particular product, by arousing fear. A well-known example in television advertising was a commercial employing the musical jingle: "Never pick up a stranger, pick up Prestone anti-freeze." This was accompanied by images of shadowy strangers (hitchhikers) who would presumably do one harm if picked up. The commercial's main appeal was not to the positive features of Prestone anti-freeze, but to the fear of what a "strange" brand might do.
In psychology, the I-change model or the Integrated Model for explaining motivational and behavioral change derives from the Attitude – Social Influence – Self-Efficacy Model, integrates ideas of Ajzen's Theory of Planned Behavior, Bandura's Social Cognitive Theory, Prochaska's Transtheoretical Model, the Health Belief Model, and Goal setting theories. Previous versions of this model have been used to explain a variety of types of health behavior.
The health action process approach (HAPA) is a psychological theory of health behavior change, developed by Ralf Schwarzer, Professor of Psychology at the Free University of Berlin, Germany.
Protection motivation theory is a theory that was originally created to help clarify fear appeals. The protection motivation theory proposes that people protect themselves based on four factors: the perceived severity of a threatening event, the perceived probability of the occurrence, or vulnerability, the efficacy of the recommended preventive behavior, and the perceived self efficacy. Protection motivation stems from both the threat appraisal and the coping appraisal. The threat appraisal assesses the severity of the situation and examines how serious the situation is. The coping appraisal is how one responds to the situation. The coping appraisal consists of both efficacy and self-efficacy. Efficacy is the individual's expectancy that carrying out recommendations can remove the threat.
