"I'm so dumb and worthless right now": factors associated with heightened momentary self-criticism in daily life.

Self-criticism is a trait associated with increased psychopathology, but self-criticism is also a personality state reflecting an action that people do in moments of time. In the current study, we explored factors associated with heightened self-criticism in daily life. Participants (N = 197) received five random prompts per day for one week on their mobile phones, where they reported their current affect (negative and positive affect), willpower self-efficacy, distress intolerance, degree of support and criticism from others, current context (location, activity, hunger, tiredness) and momentary self-criticism. We first demonstrated that self-criticism varies over time and across contexts, and is associated with heightened trait self-criticism. Then, using multilevel modelling, we explored the contextual factors associated with greater self-criticism. We found that self-criticism was higher when people were at home, and more tired. We also found higher self-criticism to be associated with greater negative and lower positive affect, greater distress intolerance, lower willpower and greater perceived criticism from others. In addition, self-criticism predicted subsequent distress intolerance, willpower and positive affect in lagged analyses. This study provides evidence that both environmental and psychological factors are associated with the dynamics of self-critical thoughts.

Because you had a bad day: the role of negative affect and justification in self-control failure.

Justification thinking (using excuses to "allow" giving into temptation) has been identified as a potential link between negative affect and self-control failure. We hypothesised that negative affect would prompt greater justification thinking, specifically deservingness thinking (i.e. "I deserve a treat"), and tested this for both inhibitory (temptation is to approach reward; self-control is to inhibit) and initiatory (temptation is to refrain from action, self-control is to initiate action) hypothetical self-control dilemmas. We found that only for inhibitory self-control (Study 1; N = 105) but not initiatory (Study 2; N = 116), negative affect resulted in greater deservingness thinking compared to neutral affect. We also hypothesised that negative mood coupled with justification would prompt greater likelihood of imagined self-control failure. We found that for inhibitory self-control (Study 3; N = 569), participants in negative affect (vs. neutral) and justification (vs. no justification) conditions were independently more likely to report they would fail at self-control. For initiatory self-control (Study 4; N = 321), we found an effect of negative affect on hypothetical self-control failure but no effect of justification. Overall, these studies confirm the role of negative affect in self-control processes and highlight differences between inhibitory and initiatory self-control situations.

Disentangling beliefs about emotions from emotion schemas.

OBJECTIVE: The current study sought to empirically evaluate a new clinical tool, the Individual Beliefs about Emotion (IBAE) which assesses nine beliefs about emotion. The goal was to examine the overlap of the IBAE with the Leahy Emotional Schema Scale (LESS), indices of psychopathology, and emotion dysregulation. METHOD: Participants (n = 513) completed the IBAE, the LESS, and measures of affective distress, borderline personality features, and emotion dysregulation. RESULTS: Results indicated that both emotion beliefs (IBAE) and schemas (LESS) were influenced by age and gender. Both measures significantly predicted variance in affective distress, borderline symptoms, and emotion dysregulation, although the LESS was a stronger predictor. CONCLUSION: We conclude that the LESS total score is a particularly useful measure of maladaptive schematic attitudes toward emotion, with additional evidence that the IBAE is a clinical tool that can be useful in psychotherapy to quickly assess a variety of emotion beliefs.

Differences in Distress Intolerance Among Daily and Intermittent Smokers.

INTRODUCTION: Distress intolerance is an important risk factor for smokers. Smokers have greater problems tolerating distress than nonsmokers, and distress intolerance is theoretically an important predictor of early lapse. However, much of the distress intolerance research has been conducted on daily smokers. Understanding distress intolerance in nondaily or intermittent smokers may help elucidate whether distress intolerance is a function of current smoking habits. AIMS AND METHODS: Daily (n = 36) and intermittent (n = 28) smokers completed behavioral distress intolerance tasks (breath holding, mirror tracing persistence, and image persistence) along with self-report measures of both general and smoking-specific distress intolerance. They also completed 1 week of ecological momentary assessment where positive and negative affect were assessed along with momentary distress intolerance, at both random times (7×/day) and immediately prior to smoking a cigarette. RESULTS: Results found no differences between intermittent and daily smokers on behavioral distress intolerance tasks or general self-reported distress intolerance. Daily smokers reported greater self-reported smoking-specific distress intolerance compared to intermittent smokers. In addition, across both smoker groups, momentary distress intolerance was higher at smoking compared to random sessions, and low positive affect predicted greater momentary distress intolerance specifically for intermittent smokers prior to smoking. CONCLUSIONS: The lack of differences between daily and intermittent smokers on general distress intolerance measures suggests that distress intolerance abilities and self-perceptions are not a function of higher levels of current smoking. However, the contextual variation in momentary distress intolerance is worth further exploration in both daily and intermittent smokers. IMPLICATIONS: The overall lack of differences between intermittent and daily smokers on distress intolerance tasks and self-report measures suggests that daily smoking is not associated with lower abilities to manage or tolerate distress at the individual difference level. However, understanding fluctuations in distress intolerance across time and context is crucial, as smokers' perceptions of their abilities to manage distress shift based on affect and smoking contexts. Stabilizing or increasing self-efficacy in tolerating distress during daily life is likely an important avenue for future research.

Examining the links between hydration knowledge, attitudes and behavior.

PURPOSE: This study aimed to examine the psychological factors (knowledge, barriers and facilitators) that can contribute to hydration-related behaviors (i.e., fluid intake) in the general population and how these relate to physical health. METHODS: A structured survey was developed to examine the links between hydration knowledge (29 items), attitudes about hydration (80 items), and fluid intake behavior (8 items) among US adults. Survey data from Phase 1 (n =301, US adults) psychometrically evaluated the items via item analysis (knowledge and fluid behavior) and factor analysis (attitudes). Phase 2 survey data (n =389, US adults and college students) refined and validated the new 16-item hydration knowledge measure, 4-item fluid intake behavior index, and 18-item attitude measure (barriers and facilitators of hydration-related behaviors) alongside indices of physical health (BMI and exercise behaviors). RESULTS: Participants had a moderate level of hydration knowledge (Phase 1: 10.91 ± 3.10; Phase 2: 10.87 ± 2.47). A five-factor measure of attitudes which assessed both facilitators (social pressure and attention to monitoring) and barriers (lack of effort, physical barriers and lack of a fluid container) to hydration demonstrated strong internal consistency (αs from 0.75 to 0.90). Attitudes about hydration-most notably barriers to hydration-were associated with indicators of health and with fluid intake behaviors, whereas hydration knowledge was not. CONCLUSIONS: Increasing hydration knowledge may be necessary for people who hold inaccurate information about hydration, but attitudes about hydration are likely to have a larger impact on fluid intake behaviors and health-related outcomes.

Non-Alcoholic Beverage Cues as Specific Comparison Images to Alcohol Image Cues.

BACKGROUND: Visual alcohol cues are often used to elicit craving (e.g., cue-reactivity), and selection of appropriate comparison cues is important to isolate the specific effect of craving for alcohol. OBJECTIVES: In the current study, via the development of a new set of non-alcoholic beverage cues, we examine measurement and methodological choices in testing alcohol images for cue-reactivity studies. METHODS: The current project combined two independent studies of hazardous (Study 1; n = 80) and recent drinkers (Study 2; n = 244) recruited from Amazon Mechanical Turk. Participants viewed either alcohol cues (Lovett, Ham, & Veilleux, 2015 ) or newly developed non-alcoholic beverage cues. We also randomly assigned people to rate the cues regarding motivational (e.g., affect, craving for alcohol, resistance to alcohol) responses or non-motivational features (e.g., artistry). RESULTS: In Study 1, we included presentation of non-beverage objects, and found that beverages were rated as more positive, less negative and with higher craving than non-beverage objects. In the combined sample, we found that the alcohol beverage cues were associated with greater craving than non-alcoholic beverage cues, and that there were no differences between cue types on either positive or negative affect. We also found an interaction between drinking experience and cue type in predicting resistance to drinking. CONCLUSIONS: We conclude that the choice of control cues in alcohol cue-reactivity studies is important, and that the currently developed non-alcoholic beverage cue set provides an adequate control for alcohol beverage cues for use in cue-reactivity paradigms.

A short-term longitudinal examination of the relations between depression, anhedonia, and self-injurious thoughts and behaviors in adults with a history of self-injury.

BACKGROUND: Limited research has addressed the role of anhedonia in predicting suicidality and/or nonsuicidal self-injury (NSSI) in adults, despite evidence suggesting that loss of interest or pleasure may increase vulnerability for self-inflicted harm, even beyond other depressive symptoms. METHODS: In the current study, we explored the role of symptoms of depression and recent changes in anhedonia in predicting suicidality, NSSI ideation, and perceptions of NSSI helpfulness among individuals with a history of NSSI or suicide attempts (N=187). RESULTS: We found that changes in anhedonia partially mediated the effect of depression on suicidality, and fully mediated the effect of depression on perceptions of NSSI helpfulness. Anhedonia did not predict NSSI ideation above and beyond depression symptoms, and did not significantly predict NSSI frequency when accounting for suicidality. Compared to individuals with a history of NSSI only or suicide attempt only, people with a history of both NSSI and suicide attempt evidenced greater risk and symptomatology. CONCLUSIONS: Results confirm the relation between anhedonia and suicidality evidenced in past research, but suggest a complex relationship between anhedonia, depression, and facets of non-suicidal self-injury.

Relationships Between Craving Beliefs and Abstinence Self-Efficacy are Mediated by Smoking Motives and Moderated by Nicotine Dependence.

INTRODUCTION: Decreased abstinence self-efficacy is linked to increased craving and negative affect, as well as poorer smoking outcomes, such as lapse, relapse, and withdrawal symptom severity. Research suggests that beliefs and cognitions concerning ourselves and the world orient us toward specific goals and thus impact our judgments and behavior. This study serves to investigate whether motives for smoking mediate the relationship between beliefs about craving and abstinence self-efficacy judgments and whether this may differ by nicotine dependence. METHODS: In a sample of 198 smokers (M age = 34.96, 51.8% female, 81.8% Caucasian), self-report measures of craving beliefs, situational abstinence self-efficacy, and smoking motives were measured. We examined the effect of beliefs on abstinence self-efficacy in both craving and negative affect situations, with craving and negative reinforcement smoking motives as mediators, and nicotine dependence as a moderator. RESULTS: Results indicate that craving beliefs predict lower abstinence self-efficacy judgments in craving situations indirectly through increased craving motives. However, this relationship was only significant for less dependent smokers. Additionally, regardless of nicotine dependence, craving beliefs predicted lower abstinence self-efficacy in negative affect situations via increased negative reinforcement smoking motives. CONCLUSIONS: These findings suggest that beliefs concerning the specific nature of craving correlate with smoking motives (ie, smoking goals) and thus abstinence self-efficacy judgments. Furthermore, these associations are stronger for less dependent smokers. Such findings suggest the importance of addressing craving beliefs during smoking cessation treatment, especially for less dependent smokers whose craving beliefs are associated with abstinence self-efficacy across multiple situations.

The Interactive Effects of Drinking Motives, Age, and Self-Criticism in Predicting Hazardous Drinking.

BACKGROUND: Individuals who disclose hazardous drinking often report strong motives to drink, which may occur to modulate views of the self. Investigating self-criticism tendencies in models of drinking motives may help explain who is more susceptible to drinking for internal or external reasons. As much of the research on drinking motives and alcohol use is conducted in young adult or college student samples, studying these relations in a wider age range is clearly needed. OBJECTIVES: The current study examined the interactive relationship between drinking motives (internal: coping, enhancement; external: social, conformity), levels of self-criticism (internalized, comparative), and age to predict hazardous drinking. METHODS: Participants (N = 427, Mage = 34.16, 54.8% female) who endorsed drinking within the last year completed an online study assessing these constructs. RESULTS: Results indicated internalized self-criticism and drinking to cope interacted to predict hazardous drinking for middle-aged adults. However, comparative self-criticism and conformity motives interacted to predict greater hazardous drinking for younger-aged adults. In addition, both social and conformity motives predicted less hazardous drinking for middle-aged adults high in comparative self-criticism. CONCLUSIONS/IMPORTANCE: Interventions that target alcohol use could minimize coping motivations to drink while targeting comparative self-criticism in the context of social, and conformity motives.

Symptoms of Psychopathology Within Groups of Eating-Disordered, Restrained Eating, and Unrestrained Eating Individuals.

OBJECTIVE: While eating-disordered individuals have shown high levels of comorbid psychopathology, there has not been an assessment of these symptoms across groups exhibiting different forms of problematic eating behavior. METHOD: Using 1,122 participants recruited via Amazon Mechanical Turk, this study examined self-reported differences between controls, restrained eaters, and individuals meeting criteria for binge eating disorder and bulimia nervosa on several measures of psychopathology unrelated to eating. RESULTS: On nearly all outcome measures, eating-disordered participants had greater symptoms of psychopathology compared to restrained eaters, who had greater levels compared to controls. Among the eating-disordered participants, bulimia nervosa participants had more symptoms of psychopathology than binge eating-disordered participants. CONCLUSION: Treatment of the populations included in this study may be informed by an understanding of the different amounts of symptoms of comorbid psychopathology that confer additional distress and impairment above and beyond disordered eating behavior.

Examining state self-criticism and self-efficacy as factors underlying hopelessness and suicidal ideation.

INTRODUCTION: When people feel hopeless, they are more likely to think about suicide. Prior work has shown that both hopelessness and suicidal ideation fluctuate over time; however, there are likely other contextual factors underlying increased hopelessness and suicidal ideation in moments of time. METHOD: In two studies using retrospective recall of a real event (Study 1, n = 268) and an experimental imaginal vignette design (Study 2, n = 356), we examined self-criticism and self-efficacy for self-regulation as crucial factors underlying hopelessness in people vulnerable to suicidal ideation. RESULTS: In both studies, greater state self-criticism and lower state self-efficacy were associated with greater hopelessness. In Study 2, we also measured suicidal ideation, and found that higher self-criticism and lower self-efficacy for self-regulation scores were associated with greater suicidal ideation, even when controlling for negative affect. Evidence of an interaction between self-criticism and self-efficacy was found with scores in Study 2 but not in Study 1; specifically, lower self-efficacy was associated with greater ideation when self-criticism was high but not when self-criticism was low. CONCLUSION: Overall, results support self-criticism and self-efficacy as important contextual factors underlying hopelessness and suicidal ideation and attending to the potential interactive effect between self-criticism and self-efficacy.

Association of Knowledge and Health Habits with Physiological Hydration Status.

The association of hydration knowledge and health habits with hydration status and fluid intake is rarely examined. We sought to determine whether knowledge or physical health behaviors predict physiological hydration status and fluid intake. Ninety-six participants (59 female; 27 ± 10 year) completed the previously validated hydration survey. Participants then recorded total fluids consumed (TFC), collected urine, and tracked void frequency for 24 h. Hydration status was assessed via 24 h urine specific gravity (USG) and osmolality (Uosm). Health behaviors included self-reported physical activity, BMI, smoking, alcoholic drinking, and sleep status. TFC was significantly correlated with 24 h USG (r = -0.390; p < 0.001), Uosm (r = -0.486; p < 0.001), total urine volume (r = 0.675; p < 0.001), and void frequency (r = 0.518; p < 0.001). Hydration knowledge was not correlated with 24 h USG (r = 0.085; p = 0.420), Uosm (r = 0.087; p = 0.419), urine total volume (r = 0.019; p = 0.857), void frequency (r = 0.030; p = 0.771), or TFC (r = 0.027; p = 0.813). Hydration knowledge did not predict 24 h USG (LR+ = 1.10; LR- = 0.90), Uosm (LR+ = 0.81; LR- = 1.35), or TFC (LR+ = 1.00; LR- = 1.00). Health habits did not predict 24 h USG, Uosm, or TFC. In conclusion, self-reported 24 h diet and fluid log recording is comparable to hydration status verification via 24 h urine collection. Hydration knowledge and health habits are not related to, or predictive of, hydration status.

The dynamics of smoking quit motivation in daily life: Associations with momentary self-regulation and nightly quit intentions.

Due to prior work suggesting dynamic fluctuations in quit motivation over time, the current study used ecological momentary assessment (EMA) to examine contextual predictors of momentary quit motivation, most notably perceived self-regulation. The sample (n = 84) intentionally excluded smokers actively trying to quit and those who plan to never quit, focusing on the group of smokers who are interested in but not yet committed to quitting. Participants completed one week of EMA, where they responded to random prompts 7x/day and logged each cigarette. At each prompt, they completed measures assessing cigarette craving, affect (positive and negative), quit motivation, and perceived momentary self-regulation (i.e., willpower self-efficacy, distress intolerance, craving uncontrollability). Participants also completed a nightly prompt where they reported their quit intentions. Results revealed that the newly developed 4-item index of quit motivation had strong psychometric properties, and demonstrated fluctuations over time and across situations. Quit motivation was higher when craving was ideographically lower than usual, and when willpower was higher than usual. People with higher distress intolerance reported higher quit motivation. In addition, stronger quit motivation and less variability in quit motivation was associated with higher quit intentions. The current study suggests that quit motivation does shift dynamically and speaks to the potential importance of targeting craving and willpower self-efficacy to enhance people's motivation to quit.

Hovering or invalidating? Examining nuances in the associations between controlling parents and problematic outcomes for college students.

Objective: The purpose of these studies was to examine whether college students' beliefs about themselves (i.e., self-compassion and beliefs about emotions) could be mechanisms explaining the relationship between problematic parenting behaviors (helicopter parenting and parental invalidation) and outcomes including perfectionism, affective distress, locus of control, and distress tolerance. Participants: Respondents included 255 (Study 1) and 277 (Study 2) college undergraduates. Methods: Simultaneous regressions and separate path analyses with helicopter parenting and parental invalidation as predictors, with self-compassion and emotion beliefs as mediators. Results: Across both studies, parental invalidation predicted perfectionism, affective distress, distress tolerance, and locus of control, and these links were often mediated by self-compassion. Self-compassion emerged as the most consistent and strongest link between parental invalidation and negative outcomes. Conclusion: People who internalize their parents' criticism and invalidation such that they hold negative beliefs about themselves (i.e., low self-compassion) may be vulnerable to negative psychosocial outcomes.

Perceived emotion invalidation predicts daily affect and stressors.

BACKGROUND AND OBJECTIVES: Perceived emotion invalidation is linked to the development or worsening of a variety of emotional and physical health conditions. However, prior studies are largely cross-sectional and whether there are day-to-day effects of generally feeling invalidated is unknown. DESIGN: We examined the relations between perceived emotion invalidation and momentary affect, average daily affect, and the experience of daily stressors among a sample of young adults using ecological momentary assessment (EMA). METHODS: Participants (n = 86) completed measures of perceived emotion invalidation and emotional reactivity at baseline then completed one week of EMA including: (1) 7x/day reports of current affect and social context and (2) 1x/day index of experienced stressors and their intensity. RESULTS: Higher perceived emotion invalidation predicted lower momentary positive affect. Perceived invalidation also interacted with social context such that higher emotion invalidation predicted greater negative affect when participants were with non-close others (i.e., co-workers, acquaintances). Only participants with high perceived emotional invalidation experienced increased stress alongside heightened daily negative affect. CONCLUSIONS: These results provide preliminary evidence that feeling emotionally invalidated may predict affective experiences, including how emotions are momentarily experienced and how life stressors are interpreted when they are later reflected on.

I can't handle my desires: Development and validation of a self-report measure of desire intolerance and associations with distress intolerance.

Desire intolerance is conceptualized as a motivational counterpoint to the transdiagnostic risk factor of distress intolerance and is defined as the inability or unwillingness to "sit with" the motivation to approach a rewarding object or task. The current work describes the development and validation of a novel measure of desire intolerance. After initial item development and exploratory factor analysis (Study 1) and confirmatory factor analysis (Study 2), the 10-item unidimensional Desire Intolerance Questionnaire (DIQ) was created. Desire intolerance was conceptually related to low self-control (Studies 1-4) and both approach and avoidance motivation (Studies 2, 4, 5) and was distinct from delay of gratification (Study 3). Greater desire intolerance was also associated with higher distress intolerance (Studies 4 and 5). In Study 4, we used qualitative coding to explore what people were thinking about when they considered their "desires." Findings revealed that higher desire intolerance was associated with thinking about desired long-term outcomes more than proximal short-term hedonic pleasures. Finally, Study 4 focused on unique and independent associations between desire and distress intolerance with psychopathology, and we found that both distress intolerance were associated with heightened psychological distress and borderline personality symptoms. Only distress intolerance was uniquely associated with uncontrolled eating and self-criticism, whereas only desire intolerance was uniquely associated with aggressive behavior and dichotomous thinking. The current research supports the DIQ as a psychometrically sound indicator of difficulties withstanding desires and allows for a better understanding of intolerance as a transdiagnostic clinical phenomena.

Clinical PhD graduate student views of their scientist-practitioner training.

OBJECTIVES: The goal of the scientist-practitioner (S-P) training model is to produce clinical psychologists equipped to integrate and utilize both science and practice in the clinical and research domains. However, much has been written regarding the possible shortcomings of S-P training and whether clinical psychology graduate students are actually gaining the knowledge and skills to integrate science and practice during graduate training and beyond (Chang, Lee, & Hargreaves, 2008; Gelso, 2006; Merlo, Collins, & Bernstein, 2008; Phillips, 1993). METHODS: As such, the present study assessed ratings of satisfaction, perception of ability, and use of the S-P training model within 653 clinical psychology graduate students enrolled in programs that are members of the Council of University Directors of Clinical Psychology. RESULTS: Findings suggest that students are consistently trained in the integration of science and practice and have confidence in their abilities to apply the S-P integration to research and clinical work. However, despite understanding the ways in which science can influence practice, over one third of students reported that they rarely use science-based decisions when informing clients of the clinical services they will be providing. CONCLUSIONS: The implications of these results support the need for a more detailed evaluation of clinical psychology graduate students as well as the use of research-informed practice and the process of providing clients with information they need to make informed choices about treatment.

Cognition and affect in imagined and recalled scenarios as a function of a specificity manipulation: An experience sampling study.

Previous work has examined the effect of specificity and temporal focus (i.e., memory vs. imagination) on people's cognition and associated affect. Here, using experience sampling methods, we take these previously addressed questions out of the laboratory into daily-life settings. Participants (N = 228) were randomly assigned to a specificity or control condition, and recorded imagined or recalled scenarios twice a day for 1 week. Results revealed a main effect of specificity where specificity prompts resulted in written scenarios that were rated by independent judges as more creative, more positive, less negative, more coherent, and incorporated more sensory content. Specificity had few direct influences on affect, though an interaction showed that imagined scenarios with specificity prompts resulted in reduced self-reported anxiety. Implications and future directions are discussed.

The Self-Invalidation Due to Emotion Scale: Development and psychometric properties.

Self-stigma involves internalized negative evaluation in people with a societally prescribed label (i.e., mental health diagnosis). Thus, measures of self-stigma due to mental illness exclude people without a diagnosis who may negatively evaluate themselves because of their emotions-a process we define as self-invalidation due to emotion. In the current research, we introduced a novel measure of self-invalidation due to emotion distinct from measures of self-stigma due to mental illness and perceived emotion invalidation. After expert review of the item pool (Study 1), and principal component (Study 2) and confirmatory factor analysis (Study 3), a 10-item scale for Self-Invalidation Due to Emotion Scale (SIDES) was developed, with subscales of self-invalidation due to high and low emotional experience. A college student and community sample (Study 4) confirmed test-retest reliability and demonstrated that greater self-invalidation due to high emotional experience predicted greater emotion dysregulation, emotional reactivity and expressivity, and beliefs about emotion uncontrollability. In contrast, greater self-invalidation due to low emotional experience predicted less emotional reactivity and expressivity, and greater beliefs about emotion controllability. Finally, in a community sample of people with a history of mental illness (Study 5), greater self-invalidation due to high but not low emotional experience predicted symptoms of borderline personality pathology and distress regardless of self-stigma due to mental illness or perceived emotion invalidation. The current research supports the SIDES as a psychometrically sound, more inclusive measure of self-stigma, relevant for predicting distress and maladaptive emotional tendencies in people with and without a mental illness.

Severity of personality dysfunction predicts affect and self-efficacy in daily life.

According to the Diagnostic and Statistical Manual for Mental Disorders, Fifth Edition (DSM-5) alterative model of personality disorders, severity of personality dysfunction theoretically involves deficits in identity, self-direction, empathy, and intimacy. We predicted that people with greater personality dysfunction would experience more problems in daily life, particularly problems associated with self-efficacy for engaging with affect and self-control (i.e., subjective willpower and distress intolerance), along with greater intensity of life stressors and higher perceived invalidation from others. Using ecological momentary assessment, participants (N = 99) were randomly prompted 7 times a day for 1 week, where they were asked questions about momentary affect, their perceived level of momentary distress tolerance, and their momentary willpower. Each night they were also asked about stressors experienced that day and intensity of their subjective response to those stressors and their daily experience of being invalidated. Results found that higher personality dysfunction, assessed at baseline, predicted greater daily negative affect, less daily positive affect, more intensely experienced stressors, and more perceived invalidation. We also found that personality dysfunction interacted with positive affect in predicting momentary self-efficacy and daily invalidation; people with greater personality dysfunction experienced lower momentary willpower, higher distress intolerance and stronger perceived invalidation alongside lower positive affect. These findings provide evidence that personality functioning influences daily life as well as support the use of the alterative model of personality disorders in conceptualizing personality pathology.
