Personality Pathology and Momentary Stress Processes

The expression of personality pathology differs between people and within a person in day-to-day life. Personality pathology may reflect, in part, dysregulation in basic behavioral processes. Thus, a useful approach for studying maladaptive trait expression comes from literature on stress and daily hassles, which provide dynamic accounts for the relations between individual differences and maladaptive dysregulation. This study sought to integrate maladaptive traits and dynamic stress processes to further dynamic models of personality pathology. In a combined clinical/community sample (N=297) oversampled for interpersonal problems, we used ecological momentary assessment (observation N=19,968) to investigate how maladaptive traits moderated the processes of stress generation, stress reactivity, and affective spillover/inertia. Tests of our preregistered hypotheses provided a mix of supportive and null findings for stress processes identified in past research, and mixed support for the moderating role of personality. The results provide insights into the relations between everyday stressors and personality pathology.

Identity and Personality Pathology: A Convergence Across the DSM-5 Personality Disorder Model and the Alternative Model for Personality Disorders

Long-standing theory regarding personality pathology as well as the recently proposed DSM-5 Alternative Model for Personality Disorders (AMPD) posit that self/identity problems are a hallmark feature cutting across forms of personality pathology. With emergence of the AMPD, researchers have started to focus empirical investigations on identity pathology as a transdiagnostic factor across personality pathology. The current study investigated identity pathology across indicators of personality pathology from both the current categorical perspective (DSM-5 PD) and the dimensional perspective in the AMPD. Identity diffusion and low self-concept clarity were correlated with all PD feature scales and all maladaptive personality dimension scales. Regression analyses revealed most indicators of personality pathology were significant correlates of identity diffusion and low self-concept clarity. Borderline and Avoidant PD feature scales and Negative Affectivity and Detachment maladaptive personality dimension scales emerged as the strongest correlates of identity pathology. The role that identity pathology plays in personality pathology is highlighted.

Comparison of Team and Participant Ratings of Event Dependence: Inferential Style, Cognitive Style, and Stress Generation

Introduction: Previous research has linked negative cognitive styles with stress generation. However, measures of cognitive styles have replied on ratings for hypothetical events, not experienced events. We examined the relationship between stress generation and attributional style for experienced events (i.e., inferential style) at both macro and daily levels.

Methods: We measured stress generation in college students using the traditional objective team ratings (i.e., observer) as well as via participants’ own ratings (i.e., actor), which we argue captures more information and is consistent with calls for participant-centered research.

Results: Cognitive style and inferential style positively correlated, indicating consistency between these two forms of assessment. Actor and observer identified events were significantly correlated for both dependent and independent events, suggesting that participants and teams are consistent in these categorizations. Results from both studies showed that inferential style was associated with actor but not observer identified dependent events.

Discussion: Our findings provide some of the first evidence for the role of inferential style in actor identified stress generation and indicate that it is useful to examine both participant and observer ratings of stressful life events.

Emotional and Social Reactivity as Mechanisms of Stress Generation: A Momentary Assessment Study

Depressed individuals report higher rates of stressful daily interpersonal events. The stress generation hypothesis suggests that traits and behaviors associated with depression may actually cause these stressors to occur. The exact day-to-day emotional and behavioral processes that drive stress generation, however, are less well understood. The present study uses experience sampling methods in a sample of 110 female undergraduate students to examine hour-by-hour emotional and social reactivity and avoidance coping as possible contributors to stress generation. Participants reported on overall symptoms of depression and then completed four daily diaries per day over a five-day period on emotional state, stressful interpersonal experiences, and avoidance behaviors. Multilevel models revealed that emotional distress both generated and was generated by interpersonal stressors such as conflict, rejection, or criticism. Avoidant behavioral responses to stressors—such as social withdrawal, substance use, or ignoring a problem—also significantly contributed to negative mood: Emotional reactivity was thus amplified by problem avoidance. Individuals who reported more depressive symptoms were especially likely to respond to negative moods with avoidance behavior. Ramifications for clinical interventions that focus on reducing emotional reactivity and avoidance coping are discussed.

Characterizing Positive and Negative Emotional Experiences in Young Adults With Borderline Personality Disorder Symptoms

OBJECTIVES

Some researchers suggest that borderline personality disorder (BPD) is characterized by elevated negative emotion; others argue that BPD involves both reduced positive and increased negative emotion. This study characterizes the emotional experiences of individuals with BPD symptoms in a combined university and community sample.

METHOD

Participants (N = 150) completed a clinical interview assessing BPD symptoms and self-report measures of positive and negative emotion. A subset (n = 106) completed a measure of emotion daily for 2 weeks. Pearson's correlations and multilevel modeling were used to examine the cross-sectional and longitudinal relationships between BPD symptoms and emotions.

RESULTS

BPD symptoms were robustly related to increased negative emotion; this relationship remained after accounting for positive emotion. BPD symptoms were weakly related to decreased positive emotion; this relationship was no longer significant after accounting for negative emotion. BPD symptoms predicted higher levels of negative and not positive emotion over 14 days. These patterns held for subscales assessing intensity, frequency, and duration of negative and positive emotions.

CONCLUSION

Findings suggest that individuals with BPD features are chiefly distinguished by elevated negative emotional experience.

Personality Disorders in Female and Male College Students With Internet Addiction

A high rate of personality disorders (PDs) was found in individuals with Internet addiction (IA) in previous studies using clinical and limited sample sizes. The present study further made comparisons between sex and incorporated a control group to compare the frequencies of PD between individuals with IA and those without IA. Five hundred fifty-six college students (341 females) completed self-report surveys and were later given diagnostic interviews to assess for a PD diagnosis. Males with IA showed a higher frequency of narcissistic PD, whereas females with IA showed a higher frequency of borderline, narcissistic, avoidant, or dependent PD when compared with those without IA. The high rate of PD among Internet addicts may be associated with the core features of specific PD psychopathology. Sex differences in the PD frequencies among IA individuals provide indications for understanding the psychopathological characteristics of PDs in Internet addicts.
