Distress tolerance is an emerging construct in psychology that has been conceptualized in several different ways. Broadly, however, it refers to an individual's "perceived capacity to withstand negative emotional and/or other aversive states (e.g. physical discomfort), and the behavioral act of withstanding distressing internal states elicited by some type of stressor." [1] Some definitions of distress tolerance have also specified that the endurance of these negative events occur in contexts in which methods to escape the distressor exist. [2]
In the literature, differences in conceptualizations of distress tolerance have corresponded with two methods of assessing this construct.
As self-report inventories fundamentally assess an individual's perception and reflection of constructs related to the self, self-report measures of distress tolerance (i.e. questionnaires) specifically focus on the perceived ability to endure distressful states, broadly defined. Some questionnaires focus specifically on emotional distress tolerance (e.g. the distress tolerance scale), [3] others on distress tolerance of negative physical states (e.g. discomfort intolerance scale), [4] and yet others focus specifically on tolerance of frustration as an overarching process of distress tolerance (e.g. frustration-discomfort scale). [5]
In contrast, studies that incorporate behavioral or biobehavioral assessments of distress tolerance provide information about real behavior rather than individuals' perceptions. Examples of stress-inducing tasks include those that require the individual to persist in tracing a computerized mirror under timed conditions (i.e. computerized mirror tracing persistence task) [6] or complete a series of time-sensitive math problems for which incorrect answers produce an aversive noise (i.e. computerized paced auditory serial addition task). [7] Some behavioral tasks are conceptualized to assess physical distress tolerance, and require individuals to hold their breath for as long as possible (breath holding task). [8]
As this is a nascent field of research, the relationships between perceptual and behavioral assessments of distress tolerance have not been clearly elucidated. Disentangling distinct components of emotional/psychological distress tolerance and physical distress tolerance within behavioral tasks also remains a challenge in the literature. [1]
Several models about the structural hierarchy of distress tolerance have been proposed. Some work suggests that physical and psychological tolerance are distinct constructs. Specifically, sensitivity to feelings of anxiety and tolerance of negative emotional states may be related to each other as aspects of a larger construct representing sensitivity and tolerance of affect broadly; discomfort surrounding physical stressors, however, was found to be an entirely separate construct not associated with sensitivity to emotional states. [9] Notably, this preliminary work was conducted with self-report measures and findings are cross-sectional in nature. The authors advise that additional longitudinal work is necessary to corroborate these relationships and elucidate directions of causality.
Recent work expands on the distinctness of emotional and physical distress tolerance to a higher-order construct of global experiential distress tolerance. This framework draws upon tolerance constructs that have been historically studied as distinct from distress tolerance. The five following constructs are framed as lower-order factors for the global distress tolerance construct, and include:
Within models that solely conceptualize distress tolerance as the ability to endure negative emotional states, distress tolerance is hypothesized to be multidimensional. This includes individual processes related to the anticipation of and experience with negative emotions, such as perceived and actual ability to tolerate the negative emotion, the appraisal of a given situation as acceptable or not, the degree to which an individual can regulate his/her emotion in the midst of a negative emotional experience, and amount of attention dedicated to processing the negative emotion. [1]
There are several candidate biological neural network mechanisms for distress tolerance. These proposed brain areas are based on the conceptualization of distress tolerance as a function of reward learning. [13] Within this framework, individuals learn to attune to and pursue reward; reduction of tension in escaping from a stressor is similarly framed as a reward and thus can be learned. Individuals differ in how quickly and for how long they display preferences for pursuing reward or in the case of distress tolerance, escaping from a distressful stimulus. Therefore, brain regions that are activated during reward processing and learning are hypothesized to also serve as neurobiological substrates for distress tolerance. For instance, activation intensity of dopamine neurons projecting to the nucleus accumbens, ventral striatum, and prefrontal cortex is associated with an individual's predicted value of an immediate reward during a learning task. As the firing rate for these neurons increases, individuals predict high values of an immediate reward. During instances in which the predicted value is correct, the basal rate of neuronal firing remains the same. When the predicted reward value is below the actual value, neuronal firing rates increase when the reward is received, resulting in a learned response. When the expected reward value is below the actual value, the firing rate of these neurons decreases below baseline levels, resulting in a learned shift that reduces expectancies about reward value. [14] It is posited that these same dopaminergic firing rates are associated with distress tolerance, in that learning the value of escaping a distressing stimulus is analogous to an estimation of an immediate reward. There are several potential clinical implications if these posited distress tolerance substrates are corroborated. It may suggest that distress tolerance is malleable among individuals; interventions that change neuronal firing rates may shift predicted values of behaviors intended to escape a distressor and provide relief, thereby increasing distress tolerance.
Other neural areas may be implicated in moderating this reward learning process. Excitability of inhibitory medium spiny neurons in the nucleus accumbens and ventral striatum have been found to moderate the association between the value of an immediate reward and probability of pursuing reward or relief. [2] Within rats, it has been demonstrated that increasing the excitability of these neurons via increased CREB expression resulted in an increased amount of time that the rats would keep their tail still when a noxious thermal paste was applied, as well as an increased amount of time spent in the open arms of a complex maze; these behaviors have been conceptualized as analogous distress tolerance in response to pain and anxiety. [15]
Distress tolerance is an emerging research topic in clinical psychology because it has been posited to contribute to the development and maintenance of several types of mental disorders, including mood and anxiety disorders such as major depressive disorder and generalized anxiety disorder, substance use and addiction, and personality disorders. [1] [16] [17] [18] In general, research on distress tolerance have found associations with these disorders that are tied closely to specific conceptualizations of distress tolerance. For instance, Borderline Personality Disorder is posited to be maintained through a chronic unwillingness to engage in or tolerate emotionally distressful states. [19] Similarly, susceptibility to developing anxiety disorders is often characterized by low emotional distress tolerance. [1] Low distress tolerance of both physical and emotional states is perceived to be a risk factor in maintaining and escalating addiction. [20] Distress tolerance is particularly important in neurobiological theories that posit that advanced stages of addiction are driven by use of a substance to avoid physical and psychological withdrawal symptoms. [21]
As a result of this interest in distress tolerance and its relationship with clinical psychopathology, several psychosocial treatments have been developed to improve distress tolerance among populations that are traditionally resistant to treatment. Many of these interventions (e.g. acceptance-based emotion regulation therapy) aims to boost distress tolerance by increasing the willingness to engage with emotion and meta-skills of acceptance of emotional conflict. [22] Other behavioral interventions include components of building distress tolerance for various treatment targets, including acceptance and commitment therapy, dialectical behavior therapy, functional analytic psychotherapy, integrative behavioral couples therapy, and mindfulness-based cognitive therapy. [1] [17] Multiple studies suggest that such distress tolerance interventions may be effective in treating generalized anxiety disorder, depression, and borderline personality disorder. [23] [24] [25] [26]
Dialectical behavior therapy (DBT) and Acceptance and commitment therapy (ACT) are therapy approaches which include specific focus on distress tolerance.
Anxiety is an emotion which is characterized by an unpleasant state of inner turmoil and includes feelings of dread over anticipated events. Anxiety is different from fear in that fear is defined as the emotional response to a real threat, whereas anxiety is the anticipation of a future threat. It is often accompanied by nervous behavior such as pacing back and forth, somatic complaints, and rumination.
Dialectical behavior therapy (DBT) is an evidence-based psychotherapy that began with efforts to treat personality disorders and interpersonal conflicts. Evidence suggests that DBT can be useful in treating mood disorders and suicidal ideation as well as for changing behavioral patterns such as self-harm and substance use. DBT evolved into a process in which the therapist and client work with acceptance and change-oriented strategies and ultimately balance and synthesize them—comparable to the philosophical dialectical process of thesis and antithesis, followed by synthesis.
Cognitive restructuring (CR) is a psychotherapeutic process of learning to identify and dispute irrational or maladaptive thoughts known as cognitive distortions, such as all-or-nothing thinking (splitting), magical thinking, overgeneralization, magnification, and emotional reasoning, which are commonly associated with many mental health disorders. CR employs many strategies, such as Socratic questioning, thought recording, and guided imagery, and is used in many types of therapies, including cognitive behavioral therapy (CBT) and rational emotive behaviour therapy (REBT). A number of studies demonstrate considerable efficacy in using CR-based therapies.
Affective neuroscience is the study of how the brain processes emotions. This field combines neuroscience with the psychological study of personality, emotion, and mood. The basis of emotions and what emotions are remains an issue of debate within the field of affective neuroscience.
Affect, in psychology, refers to the underlying experience of feeling, emotion, attachment, or mood. In psychology, "affect" refers to the experience of feeling or emotion. It encompasses a wide range of emotional states and can be positive or negative. Affect is a fundamental aspect of human experience and plays a central role in many psychological theories and studies. It can be understood as a combination of three components: emotion, mood, and affectivity. In psychology, the term "affect" is often used interchangeably with several related terms and concepts, though each term may have slightly different nuances. These terms encompass: emotion, feeling, mood, emotional state, sentiment, affective state, emotional response, affective reactivity, disposition. Researchers and psychologists may employ specific terms based on their focus and the context of their work.
Emotion dysregulation is a range of emotional responses that do not lie within a desirable scope of emotive response, considering the stimuli.
Worry refers to the thoughts, images, emotions, and actions of a negative nature in a repetitive, uncontrollable manner that results from a proactive cognitive risk analysis made to avoid or solve anticipated potential threats and their potential consequences.
In the study of psychology, neuroticism has been considered a fundamental personality trait. In the Big Five approach to personality trait theory, individuals with high scores for neuroticism are more likely than average to be moody and to experience such feelings as anxiety, worry, fear, anger, frustration, envy, jealousy, pessimism, guilt, depressed mood, and loneliness. Such people are thought to respond worse to stressors and are more likely to interpret ordinary situations, such as minor frustrations, as appearing hopelessly difficult. The responses can include maladaptive behaviors, such as dissociation, procrastination, substance use, etc., which aids in relieving the negative emotions and generating positive ones.
Childhood trauma is often described as serious adverse childhood experiences (ACEs). Children may go through a range of experiences that classify as psychological trauma; these might include neglect, abandonment, sexual abuse, emotional abuse, and physical abuse, witnessing abuse of a sibling or parent, or having a mentally ill parent. These events have profound psychological, physiological, and sociological impacts and can have negative, lasting effects on health and well-being such as unsocial behaviors, attention deficit hyperactivity disorder (ADHD), and sleep disturbances. Similarly, children whose mothers have experienced traumatic or stressful events during pregnancy have an increased risk of mental health disorders and other neurodevelopmental disorders.
Social anxiety is the anxiety and fear specifically linked to being in social settings. Some categories of disorders associated with social anxiety include anxiety disorders, mood disorders, autism spectrum disorders, eating disorders, and substance use disorders. Individuals with higher levels of social anxiety often avert their gazes, show fewer facial expressions, and show difficulty with initiating and maintaining a conversation. Social anxiety commonly manifests itself in the teenage years and can be persistent throughout life; however, people who experience problems in their daily functioning for an extended period of time can develop social anxiety disorder. Trait social anxiety, the stable tendency to experience this anxiety, can be distinguished from state anxiety, the momentary response to a particular social stimulus. Half of the individuals with any social fears meet the criteria for social anxiety disorder. Age, culture, and gender impact the severity of this disorder. The function of social anxiety is to increase arousal and attention to social interactions, inhibit unwanted social behavior, and motivate preparation for future social situations.
Emotional self-regulation or emotion regulation is the ability to respond to the ongoing demands of experience with the range of emotions in a manner that is socially tolerable and sufficiently flexible to permit spontaneous reactions as well as the ability to delay spontaneous reactions as needed. It can also be defined as extrinsic and intrinsic processes responsible for monitoring, evaluating, and modifying emotional reactions. Emotional self-regulation belongs to the broader set of emotion regulation processes, which includes both the regulation of one's own feelings and the regulation of other people's feelings.
Rumination is the focused attention on the symptoms of one's mental distress, and on its possible causes and consequences, as opposed to its solutions, according to the Response Styles Theory proposed by Nolen-Hoeksema (1998).
Interoceptive exposure is a cognitive behavioral therapy technique used in the treatment of panic disorder. It refers to carrying out exercises that bring about the physical sensations of a panic attack, such as hyperventilation and high muscle tension, and in the process removing the patient's conditioned response that the physical sensations will cause an attack to happen.
Experiential avoidance (EA) has been broadly defined as attempts to avoid thoughts, feelings, memories, physical sensations, and other internal experiences — even when doing so creates harm in the long run. The process of EA is thought to be maintained through negative reinforcement — that is, short-term relief of discomfort is achieved through avoidance, thereby increasing the likelihood that the avoidance behavior will persist. Importantly, the current conceptualization of EA suggests that it is not negative thoughts, emotions, and sensations that are problematic, but how one responds to them that can cause difficulties. In particular, a habitual and persistent unwillingness to experience uncomfortable thoughts and feelings is thought to be linked to a wide range of problems.
Anxiety sensitivity (AS) refers to the fear of behaviours or sensations associated with the experience of anxiety, and a misinterpretation of such sensations as dangerous. Bodily sensations related to anxiety, such as nausea and palpitations, are mistaken as harmful experiences, causing anxiety or fear to intensify. For example, a person with high anxiety sensitivity may fear the shakes as impending neurological disorder, or may suspect lightheadedness is the result of a brain tumour; conversely, a person with low anxiety sensitivity is likely to identify these as harmless and attach no significance to them. The Anxiety Sensitivity Index attempts to assess anxiety sensitivity.
Fear of negative evaluation (FNE) or fear of failure, also known as atychiphobia, is a psychological construct reflecting "apprehension about others' evaluations, distress over negative evaluations by others, and the expectation that others would evaluate one negatively". The construct and a psychological test to measure it were defined by David Watson and Ronald Friend in 1969. FNE is related to specific personality dimensions, such as anxiousness, submissiveness, and social avoidance. People who score high on the FNE scale are highly concerned with seeking social approval or avoiding disapproval by others and may tend to avoid situations where they have to undergo evaluations. High FNE subjects are also more responsive to situational factors. This has been associated with conformity, pro-social behavior, and social anxiety.
Cognitive emotional behavioral therapy (CEBT) is an extended version of cognitive behavioral therapy (CBT) aimed at helping individuals to evaluate the basis of their emotional distress and thus reduce the need for associated dysfunctional coping behaviors. This psychotherapeutic intervention draws on a range of models and techniques including dialectical behavior therapy (DBT), mindfulness meditation, acceptance and commitment therapy (ACT), and experiential exercises.
Interpersonal emotion regulation is the process of changing the emotional experience of one's self or another person through social interaction. It encompasses both intrinsic emotion regulation, in which one attempts to alter their own feelings by recruiting social resources, as well as extrinsic emotion regulation, in which one deliberately attempts to alter the trajectory of other people's feelings.
Emotional eating, also known as stress eating and emotional overeating, is defined as the "propensity to eat in response to positive and negative emotions". While the term commonly refers to eating as a means of coping with negative emotions, it sometimes include eating for positive emotions, such as overeating when celebrating an event or to enhance an already good mood.
Emotions play a key role in overall mental health, and sleep plays a crucial role in maintaining the optimal homeostasis of emotional functioning. Deficient sleep, both in the form of sleep deprivation and restriction, adversely impacts emotion generation, emotion regulation, and emotional expression.
