Numerous studies around the world have found a relationship between socioeconomic status and mental health. There are higher rates of mental illness in groups with lower socioeconomic status (SES), but there is no clear consensus on the exact causative factors. The two principal models that attempt to explain this relationship are the social causation theory, which posits that socioeconomic inequality causes stress that gives rise to mental illness, and the downward drift approach, which assumes that people predisposed to mental illness are reduced in socioeconomic status as a result of the illness. Most literature on these concepts dates back to the mid-1990s and leans heavily towards the social causation model.
The social causation theory is an older theory with more evidence and research behind it. [1] This hypothesis states that one's socioeconomic status (SES) is the cause of weakening mental functions. As Perry writes in The Journal of Primary Prevention, "members of the lower social classes experience excess psychological stress and relatively few societal rewards, the results of which are manifested in psychological disorder". [2] The excess stress that people with low SES experience could be inadequate health care, [3] job insecurity, [4] and poverty, [5] which can bring about many other psycho-social and physical stressors like crowding, discrimination, crime, etc. [6] Thus, lower SES predisposes individuals to the development of a mental illness.[ further explanation needed ]
The Faris and Dunham (1939), Hollingshead and Redlich (1958), and Midtown Manhattan (1962) studies are three of the most influential [2] in the debate between social causation and downward drift. They lend important evidence [2] to the linear correlation between mental illness and SES, more specifically that a low SES produces a mental illness. The higher rates of mental illness in lower SES are likely due to the greater stress individuals experience. Issues that are not experienced in high SES, such as lack of housing, hunger, unemployment, etc., contribute to the psychological stress levels that can lead to the onset of mental illness. Additionally, while experiencing greater stress levels, there are fewer societal rewards and resources for those at the bottom of the socioeconomic ladder. The moderate economics assets available to those just one level above the lowest socioeconomic group allows them to take preventative action or treatment for psychoses. However, the hypothesis of the social causation model is disputed by the downward drift model.
Faris and Dunham analyzed the prevalence of mental disorders, including schizophrenia, in different areas of Chicago. The researchers plotted the homes of patients preceding their admission to hospitals. They found a remarkable increase of cases from the outskirts of the city moving inwards to the center. This reflected other rates of distributions, such as unemployment, poverty and family desertion. They also found that cases of schizophrenia were most pervasive in public housing neighborhoods as well as communities with higher numbers of immigrants. This was one of the first empirical, evidence-based studies supporting social causation theory. [7]
Hollingshead and Redlich conducted a study in New Haven, Connecticut, that was considered a major breakthrough in this field of research. [2] The authors identified anyone who was hospitalized or in treatment for mental illness by looking at files from clinics, hospitals, and the like. They were able to design a valid and reliable construct to relate these findings to social class using education and occupation as measures for five social class groups. Their results showed high disproportions of schizophrenia among the lowest social group. They also found that the lower people were on the scale of social class, the likelier they were to be admitted to a hospital for psychosis. [8]
The study by Srole, Langer, Micheal, Opler, and Rennie, known as the Midtown Manhattan Study, has become a quintessential study in mental health. [2] The main focus of the research was to "uncover [the] unknown portion of mental illness which is submerged in the community and thus hidden from sociological and psychiatric investigators alike". [9] The researchers managed to probe deep into the community to include subjects usually left out of such studies. The experimenters used both parental and personal SES to investigate the correlation between mental illness and social class. When basing their results on parental SES, approximately 33 percent of Midtown inhabitants in the lowest SES showed some signs of impairments in mental functioning while only 18 percent of the inhabitants in the highest SES showed these signs. When assessing the relationship based on personal SES, 47 percent of inhabitants in the lowest SES showed signs of weakening mental functions while only 13 percent of the highest SES demonstrated these symptoms. These findings remained the same for all ages and genders. [9]
In contrast to social causation, downward drift (also known as social selection) postulates that there is likely a genetic component that causes the onset of mental illness which may then lead to "a drift down into or fail to rise out of lower SES groups". [10] This means that a person's SES level is a consequence rather than a cause of weakening mental functions. The downward drift theory shows promise [11] specifically for individuals with a diagnosis of schizophrenia.
The Weich and Lewis study was conducted in the United Kingdom where researchers looked at 7,725 adults who had developed mental illnesses. They found that while low SES and unemployment may increase the length of psychiatric episodes they did not increase the likelihood of the initial psychotic break. [12]
In the Isohanni et al. longitudinal study in Finland, the researchers looked at patients treated in hospitals for mental disorders and who were aged between 16 and 29. The study followed the patients for 31 years and looked at how their illness affected their educational achievement. The study had a total of 80 patients and it compared patients who had been treated in the hospital for diagnoses of schizophrenia, and other psychotic or non-psychotic diagnoses, to those of the same 1966 birth cohort who had received no psychiatric treatment. They found that individuals who were hospitalized at 22 years or younger (early onset) were more likely to only complete a basic level of education and remain stagnant. [13]
Some patients were able to complete secondary education, but none advanced to tertiary education. Those who had not been hospitalized had lower completion rates of basic education but much higher percentages of completing both secondary and tertiary education, 62% and 26%, respectively. This study suggests that mental disorders, especially schizophrenia, impede educational achievement. The inability to complete higher education may be one of the possible contributors to the downward drift in SES by individuals with mental illness. [14]
The researchers in the Wiersma, Giel, De Jong and Slooff study looked at both educational and occupational attainment of patients with psychosis compared to their fathers. Researchers assessed both topic areas in the fathers as well as in the patients. In a two-year follow-up, the downward mobility in both education and occupation was greater than expected in the patients. Only a small percentage of patients were able to keep their job or find a new one after the onset of psychosis. Most of the individuals participating in the study had a lower SES than when they were born. This study also showed that the drift may begin with prodromal symptoms rather than at full onset. [15] [16]
Many researchers argue against the downward drift model, because unlike its counterpart, "it does not address the psychological stress of being impoverished and fails to validate that persistent economic stress can lead to psychological disturbance". [2] Mirowsky and Ross [17] discuss in their book, Social Causes of Psychological Distress, that stress frequently stems from lack of control, or the feeling of lack of control, over one's life. Those in lower SES have a minimal sense of control over the events that occur in their lives. [17]
They argue that lack of control does not only stem from jobs with low income, but that "minority status also lowers the sense of control, partly because of lower education, income, and unemployment, and partly because any given level of achievement requires greater effort and provides fewer opportunities". [17] The arguments posed in their book support social causation since such high stress levels are involved. Although both models can be existing, they do not need to be mutually exclusive, researchers tend to agree that downward drift has more relevance to someone diagnosed with schizophrenia. [17]
According to a 2009 meta-analysis by Paul and Moser, countries with high income inequality and poor unemployment protections have worse mental health outcomes among the unemployed. [18]
Although social causation can explain some forms of mental illnesses, downward drift "has the greatest empirical support and is one of the cardinal features of schizophrenia". [11] The downward drift theory is more applicable to schizophrenia for a number of reasons. There are varying degrees of the disease, but once a psychotic break is experienced, the person often cannot function at the same level as before. This impairment affects all areas of life—education, occupation, social and family connections, etc. Due to the many challenges, patients will likely drift to a lower SES because they are unable to keep up with previous standards.
Another reason why the downward drift theory is preferred is that, unlike other mental illnesses such as depression, once someone is diagnosed with schizophrenia they have the diagnosis for life. [19] While symptoms may not be constant, "individuals with this diagnosis often experience cycles of remission and relapse throughout their lives". [20]
This explains the large discrepancy between the incidence of schizophrenia and prevalence of the disease. There is a very low rate of new cases of schizophrenia in comparison to the number of total cases because "it often starts in early adult life and becomes chronic". [19] Patients will usually function at a lower level once the illness has manifested itself. Even with the help of antipsychotic medication and psycho-social support, most patients will still experience some symptoms [21] making moving up out of a lower SES nearly impossible.
Another possible explanation discussed in literature regarding[ improper synthesis? ] the relation between the downward drift theory and schizophrenia is the stigma associated with mental illness. Individuals with mental illness are often treated differently, usually negatively, by their community. [22] Although great strides have been made, mental illness is often unfavorably stigmatized. As Livingston explains, "stigma can produce a negative spiraling effect on the life course of people with mental illnesses, which tends to create...a decline in social class". [22]
Individuals who develop schizophrenia cannot function at the level they are used to, and "are particularly likely to experience the effects of ostracism, being amongst the most stigmatized of all the mental illnesses." [23] The complete exclusion they experience helps to maintain their new lower status, preventing any upward mobility. The downward drift theory may be mainly applicable to schizophrenia; however, it may also apply to other mental illnesses since each is accompanied by a negative stigma.
While it can be hard to maintain status once the schizophrenia appears, some individuals are able to resist a downward drift, particularly if they start out at a higher SES. For example, if a person is from a high SES, they have the ability to access preventative resources and possible treatment for the disease which can help buffer the drift downwards and help maintain their status. It is also important for those with schizophrenia to have a strong network of friends and family [24] because friends and family may notice signs of the illness before full onset. [25] For example, individuals that are married show less of a drift downwards than those who are not. [26] Individuals who do not have a support system may show early signs of psychotic symptoms that go unnoticed and untreated.
A mental disorder, also referred to as a mental illness, a mental health condition, or a psychiatric disability, is a behavioral or mental pattern that causes significant distress or impairment of personal functioning. A mental disorder is also characterized by a clinically significant disturbance in an individual's cognition, emotional regulation, or behavior, often in a social context. Such disturbances may occur as single episodes, may be persistent, or may be relapsing–remitting. There are many different types of mental disorders, with signs and symptoms that vary widely between specific disorders. A mental disorder is one aspect of mental health.
Psychosis is a condition of the mind or psyche that results in difficulties determining what is real and what is not real. Symptoms may include delusions and hallucinations, among other features. Additional symptoms are incoherent speech and behavior that is inappropriate for a given situation. There may also be sleep problems, social withdrawal, lack of motivation, and difficulties carrying out daily activities. Psychosis can have serious adverse outcomes.
Paranoia is an instinct or thought process that is believed to be heavily influenced by anxiety, suspicion, or fear, often to the point of delusion and irrationality. Paranoid thinking typically includes persecutory beliefs, or beliefs of conspiracy concerning a perceived threat towards oneself. Paranoia is distinct from phobias, which also involve irrational fear, but usually no blame.
A mental disorder is an impairment of the mind disrupting normal thinking, feeling, mood, behavior, or social interactions, and accompanied by significant distress or dysfunction. The causes of mental disorders are very complex and vary depending on the particular disorder and the individual. Although the causes of most mental disorders are not fully understood, researchers have identified a variety of biological, psychological, and environmental factors that can contribute to the development or progression of mental disorders. Most mental disorders result in a combination of several different factors rather than just a single factor.
The topic and directed area of focus for this section is Psychopathology. Psychopathology is the studied idea of varies thoughts, behaviors, and emotions expressed. These three are expressed very differently throughout each individual. Psychiatric disability can be developed from an altered behavior, emotion, or thought. Some of the major sections included within the article are read as supernatural and psychological explanations as well as a range of many other mental disorders listed and described in the latter portion of the article. Psychopathology is a heavily researched and studied area in the field of psychology.
Schizoaffective disorder is a mental disorder characterized by abnormal thought processes and an unstable mood. This diagnosis requires symptoms of both schizophrenia (psychosis) and a mood disorder: either bipolar disorder or depression. The main criterion is the presence of psychotic symptoms for at least two weeks without any mood symptoms. Schizoaffective disorder can often be misdiagnosed when the correct diagnosis may be psychotic depression, bipolar I disorder, schizophreniform disorder, or schizophrenia. This is a problem as treatment and prognosis differ greatly for most of these diagnoses. Many people with schizoaffective disorder have other mental disorder including anxiety disorders.
Delusional disorder, traditionally synonymous with paranoia, is a mental illness in which a person has delusions, but with no accompanying prominent hallucinations, thought disorder, mood disorder, or significant flattening of affect. Delusions are a specific symptom of psychosis. Delusions can be bizarre or non-bizarre in content; non-bizarre delusions are fixed false beliefs that involve situations that could occur in real life, such as being harmed or poisoned. Apart from their delusion or delusions, people with delusional disorder may continue to socialize and function in a normal manner and their behavior does not necessarily seem odd. However, the preoccupation with delusional ideas can be disruptive to their overall lives.

A thought disorder (TD) is a disturbance in cognition which affects language, thought and communication. Psychiatric and psychological glossaries in 2015 and 2017 identified thought disorders as encompassing poverty of ideas, neologisms, paralogia, word salad, and delusions—all disturbances of thought content and form. Two specific terms have been suggested—content thought disorder (CTD) and formal thought disorder (FTD). CTD has been defined as a thought disturbance characterized by multiple fragmented delusions, and the term thought disorder is often used to refer to an FTD: a disruption of the form of thought. Also known as disorganized thinking, FTD results in disorganized speech and is recognized as a major feature of schizophrenia and other psychoses. Disorganized speech leads to an inference of disorganized thought. Thought disorders include derailment, pressured speech, poverty of speech, tangentiality, verbigeration, and thought blocking. One of the first known cases of thought disorders, or specifically OCD as it is known today, was in 1691. John Moore, who was a bishop, had a speech in front of Queen Mary II, about "religious melancholy."
Mental health encompasses emotional, psychological, and social well-being, influencing cognition, perception, and behavior. According to World Health Organization (WHO), it is a "state of well-being in which the individual realizes his or her abilities, can cope with the normal stresses of life, can work productively and fruitfully, and can contribute to his or her community". It likewise determines how an individual handles stress, interpersonal relationships, and decision-making. Mental health includes subjective well-being, perceived self-efficacy, autonomy, competence, intergenerational dependence, and self-actualization of one's intellectual and emotional potential, among others. From the perspectives of positive psychology or holism, mental health may include an individual's ability to enjoy life and to create a balance between life activities and efforts to achieve psychological resilience. Cultural differences, personal philosophy, subjective assessments, and competing professional theories all affect how one defines "mental health". Some early signs related to mental health difficulties are sleep irritation, lack of energy, lack of appetite, thinking of harming oneself or others, self-isolating, and frequently zoning out.
Social psychiatry is a branch of psychiatry that focuses on the interpersonal and cultural context of mental disorder and mental wellbeing. It involves a sometimes disparate set of theories and approaches, with work stretching from epidemiological survey research on the one hand, to an indistinct boundary with individual or group psychotherapy on the other. Social psychiatry combines a medical training and perspective with fields such as social anthropology, social psychology, cultural psychiatry, sociology and other disciplines relating to mental distress and disorder. Social psychiatry has been particularly associated with the development of therapeutic communities, and to highlighting the effect of socioeconomic factors on mental illness. Social psychiatry can be contrasted with biopsychiatry, with the latter focused on genetics, brain neurochemistry and medication. Social psychiatry was the dominant form of psychiatry for periods of the 20th century but is currently less visible than biopsychiatry.
The trauma model of mental disorders, or trauma model of psychopathology, emphasises the effects of physical, sexual and psychological trauma as key causal factors in the development of psychiatric disorders, including depression and anxiety as well as psychosis, whether the trauma is experienced in childhood or adulthood. It conceptualises people as having understandable reactions to traumatic events rather than suffering from mental illness.
Gender is correlated with the prevalence of certain mental disorders, including depression, anxiety and somatic complaints. For example, women are more likely to be diagnosed with major depression, while men are more likely to be diagnosed with substance abuse and antisocial personality disorder. There are no marked gender differences in the diagnosis rates of disorders like schizophrenia and bipolar disorder. Men are at risk to suffer from post-traumatic stress disorder (PTSD) due to past violent experiences such as accidents, wars and witnessing death, and women are diagnosed with PTSD at higher rates due to experiences with sexual assault, rape and child sexual abuse. Nonbinary or genderqueer identification describes people who do not identify as either male or female. People who identify as nonbinary or gender queer show increased risk for depression, anxiety and post-traumatic stress disorder. People who identify as transgender demonstrate increased risk for depression, anxiety, and post-traumatic stress disorder.
Suicide risk assessment is a process of estimating the likelihood for a person to attempt or die by suicide. The goal of a thorough risk assessment is to learn about the circumstances of an individual person with regard to suicide, including warning signs, risk factors, and protective factors. Risk for suicide is re-evaluated throughout the course of care to assess the patient's response to personal situational changes and clinical interventions. Accurate and defensible risk assessment requires a clinician to integrate a clinical judgment with the latest evidence-based practice, although accurate prediction of low base rate events, such as suicide, is inherently difficult and prone to false positives.
Schizophrenia is a neurodevelopmental disorder with no precise or single cause. Schizophrenia is thought to arise from multiple mechanisms and complex gene–environment interactions with vulnerability factors. Risk factors of schizophrenia have been identified and include genetic factors, environmental factors such as experiences in life and exposures in a person's environment, and also the function of a person's brain at it develops. The interactions of these risk factors are intricate, as numerous and diverse medical insults from conception to adulthood can be involved. Many theories have been proposed including the combination of genetic and environmental factors may lead to deficits in the neural circuits that affect sensory input and cognitive functions.
Dual diagnosis is the condition of having a mental illness and a comorbid substance use disorder. There is considerable debate surrounding the appropriateness of using a single category for a heterogeneous group of individuals with complex needs and a varied range of problems. The concept can be used broadly, for example depression and alcohol use disorder, or it can be restricted to specify severe mental illness and substance use disorder, or a person who has a milder mental illness and a drug dependency, such as panic disorder or generalized anxiety disorder and is dependent on opioids. Diagnosing a primary psychiatric illness in people who use substances is challenging as substance use disorder itself often induces psychiatric symptoms, thus making it necessary to differentiate between substance induced and pre-existing mental illness.
Drift hypothesis, concerning the relationship between mental illness and social class, is the argument that illness causes one to have a downward shift in social class. The circumstances of one's social class do not cause the onset of a mental disorder, but rather, an individual's deteriorating mental health occurs first, resulting in low social class attainment. The drift hypothesis is the opposing theory of the social causation thesis, which says being in a lower social class is a contributor to the development of a mental illness.
Brief psychotic disorder—according to the classifications of mental disorders DSM-IV-TR and DSM-5—is a psychotic condition involving the sudden onset of at least one psychotic symptom lasting 1 day to 1 month, often accompanied by emotional turmoil. Remission of all symptoms is complete with patients returning to the previous level of functioning. It may follow a period of extreme stress including the loss of a loved one. Most patients with this condition under DSM-5 would be classified as having acute and transient psychotic disorders under ICD-10. Prior to DSM-IV, this condition was called "brief reactive psychosis." This condition may or may not be recurrent, and it should not be caused by another condition.
Cognitive epidemiology is a field of research that examines the associations between intelligence test scores and health, more specifically morbidity and mortality. Typically, test scores are obtained at an early age, and compared to later morbidity and mortality. In addition to exploring and establishing these associations, cognitive epidemiology seeks to understand causal relationships between intelligence and health outcomes. Researchers in the field argue that intelligence measured at an early age is an important predictor of later health and mortality differences.
Mental health inequality refers to the differences in the quality, access, and health care different communities and populations receive for mental health services. Globally, the World Health Organization estimates that 350 million people are affected with depressive disorders. Mental health can be defined as an individual's well-being and/or the absence of clinically defined mental illness. Inequalities that can occur in mental healthcare may include mental health status, access to and quality of care, and mental health outcomes, which may differ across populations of different race, ethnicity, sexual orientation, sex, gender, socioeconomic statuses, education level, and geographic location. Social determinants of health, more specifically the social determinants of mental health, that can influence an individual's susceptibility to developing mental disorders and illnesses include, but are not limited to, economic status, education level, demographics, geographic location and genetics.
