The impact of trauma-focused psychotherapy for posttraumatic stress disorder on interpersonal functioning: A systematic review and meta-analysis of randomized clinical trials.

Interpersonal functioning is a common concern for people with postttraumatic stress disorder (PTSD) but is not a key target of most trauma-focused psychotherapies (TFPs). We preregistered and undertook a systematic review and meta-analysis of randomized clinical trials (RCTs) examining the efficacy of TFPs for improving interpersonal functioning. Studies were identified through the PTSD Trials Standardized Data Repository, scholarly databases, and the solicitation of unpublished data from the PTSD research community following current PRISMA guidelines. We used random effects meta-analysis to estimate within-group change (i.e., pre- to posttreatment) in interpersonal functioning. Meta-analytic findings yielded a medium total effect of TFP on interpersonal functioning, g = 0.54, 95% CI [0.37, 0.72], with high between-study heterogeneity. Sensitivity analyses yielded substantively equivalent point estimates when outliers were excluded, g = 0.55, and when only the most well-established individual TFPs were included, g = 0.57. In contrast, allocation to a control condition was associated with little average change in interpersonal functioning, g = 0.04 [-0.12, 0.21]. Formal tests did not yield clear evidence of publication bias. Bias-corrected estimates varied but centered around a medium effect, gs = 0.41-1.11. There was a medium-to-large association between change in interpersonal functioning and change in PTSD symptoms, rs = -.35--.44. The extant literature on TFPs and interpersonal functioning is small and heterogeneous, indicating the need for more focused attention on this outcome. Results suggest that, on average, TFPs are moderately efficacious for improving interpersonal functioning; however, additional treatment may be needed to meet the desired level of improvement.

Emotion-related impulsivity and suicidal ideation: Towards a more specific model.

OBJECTIVES: Suicidal ideation is a pervasive and painful experience that varies considerably in its phenomenology. Here, we consider how one key risk variable might inform our understanding of variation in suicidal ideation: emotion-related impulsivity, the trait-like tendency towards unconstrained speech, behaviour, and cognition in the face of intense emotions. We hypothesized that emotion-related impulsivity would be tied to specific features, including severity, perceived lack of controllability, more rapidly fluctuating course, higher scores on a measure of acute suicidal affective disturbance, and more emotional and cognitive disturbance as antecedents. METHODS: We recruited two samples of adults (Ns = 421, 221) through Amazon Mechanical Turk (MTurk), with oversampling of those with suicidal ideation. Both samples completed psychometrically sound self-report measures online to assess emotion- and non-emotion-related dimensions of impulsivity and characteristics of suicidal ideation. RESULTS: One form of emotion-related impulsivity related to the severity, uncontrollability, dynamic course, and affective and cognitive precursors of ideation. CONCLUSIONS: Despite limitations of the cross-sectional design and self-report measures, the current findings highlight the importance of specificity in considering key dimensions of impulsivity and suicidal ideation.

The effect of nanoparticle location and shape on thermal transitions observed in hydrated layer-by-layer assemblies.

Nanoparticles can have a profound effect on thermal transitions observed in polymer nanocomposites. Many layer-by-layer (LbL) assemblies contain nanoparticles for added functionality, but the resulting effects of nanoparticles on an LbL film's thermal properties are not known. Previously, we have shown that a nanoparticle-free LbL film containing strong polyelectrolytes, poly(diallyldimethylammonium chloride)/poly(styrene sulfonate) (PDAC/PSS), exhibited a single reversible thermal transition much like a glass-melt transition. In the work presented here, nanoparticles of either spherical (SiO2) or platelet (Laponite clay) shape are inserted at varying vertical locations throughout PDAC/PSS LbL films. Temperature-controlled quartz crystal microbalance (QCM-D) and modulated differential scanning calorimetry (MDSC) are applied, for which QCM-D proved to be more sensitive to the transition. All Laponite-containing films possess two thermal transitions. During growth, Laponite-containing films exhibit steady increases in dissipation, which is proposed to arise from mechanically decoupled regions separated by the Laponite nanoparticles. For SiO2-containing films, three transitions are detectable only when the SiO2 nanoparticles are placed in the middle of the film; no transitions are observed for SiO2 placed at the bottom or top, perhaps because of a weakening of the transition. The lowest transition is close in value to that of neat PDAC/PSS LbL films, and was assigned to a "bulk" response. The higher transition(s) is attributed to polymer chains in an interfacial region near the nanoparticle. We propose that nanoparticles restrict segmental mobility, thus elevating the transition temperature in the interfacial region.

A multisample investigation of links between individual differences in emotion dysregulation and perceived helpfulness of interpersonal emotion regulation interactions.

Prior theory and research offer competing predictions for associations between intrapersonal emotion (dys)regulation and interpersonal emotion regulation (IER). One possibility is that difficulties recognizing, accepting, or managing one's emotions might tend to interfere with seeking or benefiting from IER. Alternatively, people who struggle to regulate their emotions by themselves might nevertheless be able to outsource regulatory functions or capitalize on regulatory support effectively, such that benefits of IER might be preserved or even amplified. We conducted secondary analyses of five samples (Ns = 90-381) collected between 2016 and 2020 to examine links between individual differences in intrapersonal emotion (dys)regulation and reported desire for, seeking of, and helpfulness of receiving IER. The samples consisted of students at a public university in California (Samples 1-3), romantic couples recruited predominantly from the Greater San Francisco Bay Area community (Sample 4), and adults reporting difficulties with emotion-related impulsivity enrolled in an online intervention to reduce aggression (Sample 5). Methods varied across samples, including questionnaires, autobiographical recall, nightly diaries, and ecological momentary assessment. Across samples, individual differences in emotion dysregulation, cognitive reappraisal, and expressive suppression were more robustly tied to perceived helpfulness of IER than reported desire for IER. More specifically, emotion dysregulation and suppression use were negatively associated with helpfulness, whereas reappraisal use was positively associated with helpfulness; however, some results were inconsistent across samples. We examine these consistencies and inconsistencies considering differences in sample characteristics and methods. We discuss conceptual and practical implications of these findings alongside strengths, limitations, and future directions. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Shame on me for needing you: A multistudy examination of links between receiving interpersonal emotion regulation and experiencing shame.

Recent theory and research have drawn attention to interpersonal dimensions of emotion regulation. Yet, few empirical investigations of the outcomes of interpersonal emotion regulation have been conducted. We propose that one negative affective outcome of received interpersonal emotion regulation of conceptual and practical interest is shame. In the present series of studies, participants from six disparate samples reported on experiences of receiving interpersonal emotion regulation using autobiographical recall and ecological sampling paradigms (total analyzed n = 1,868; total analyzed k = 2,515 instances of receiving interpersonal emotion regulation). We sought to quantify the frequency and distinctiveness of shame as an outcome of receiving interpersonal emotion regulation. We used an exploratory-confirmatory approach to identify robust and generalizable correlates of shame. We considered individual (e.g., trait external shame-proneness), situational (e.g., desire for regulation), relational (e.g., perceived closeness with the provider), and interaction-specific (e.g., perceptions of provider hostility) variables. Our results indicate that it is not uncommon for people to experience receiving interpersonal emotion regulation as shame-inducing, and these perceptions are distinct from their evaluations of the overall helpfulness of the interaction. An internal mini meta-analysis showed that the strongest correlates of shame across studies and samples were individual differences in nonacceptance of negative emotions and expressive suppression and interaction-specific ratings of provider responsiveness and hostility. We discuss the conceptual, methodological, and practical implications of these findings for studying interpersonal emotion regulation and shame.

Who disengages from emotion and when? An EMA study of how urgency and distress intolerance relate to daily emotion regulation.

Overreliance on disengagement emotion regulation strategies (e.g., emotion avoidance, emotion suppression) has been shown to relate to poor clinical outcomes. Two traits characterized by difficulties in goal-directed responses to emotion-urgency and distress intolerance-may help explain who is likely to disengage from emotion and when. These traits are associated with diverse forms of psychopathology and greater reliance on disengagement strategies. Gaps remain about how these traits relate to emotion regulation in daily life. The present study uses ecological momentary assessment (EMA) to determine the associations of urgency and distress intolerance with momentary high arousal negative affect and momentary attempts to regulate negative emotions. Participants (N = 101) were college students who endorsed at least weekly behaviors often characterized by emotion dysregulation (e.g., self-harm, binging/purging, alcohol/drug use). Participants completed trait measures at baseline and EMA surveys of momentary affect and emotion regulation, six times daily for 4 days. Results indicated that at certain levels, urgency and distress intolerance moderated the relationship between high arousal negative affect and disengagement from emotion: low urgency scores related to relatively greater disengagement from emotion following reported high arousal negative affect, whereas high distress intolerance scores related to relatively greater disengagement following high arousal negative affect. Findings support the role of both urgency and distress intolerance in the relationship between high arousal negative affect and disengagement, which implicates the utility of clinical interventions that focus on emotion regulation, especially during high arousal states.

The Interpersonal Regulation Interaction Scale (IRIS): A multistudy investigation of receivers' retrospective evaluations of interpersonal emotion regulation interactions.

Recent conceptual and empirical advances have focused on interpersonal dimensions of emotion regulation and, more specifically, to the features of attempted support transactions that shape the outcomes of enacted support. We conducted 2 autobiographical recall studies to investigate receivers' evaluations of intrinsic interpersonal emotion regulation interactions, to ascertain the number of dimensions required to capture variation in those evaluations, and then to examine associations of those dimensions with perceived benefits of the interactions. To do so, we developed a new questionnaire, the Interpersonal Regulation Interaction Scale (IRIS). In Study 1 (n = 390), an exploratory factor analysis (EFA) of the IRIS yielded 4 dimensions, which we labeled responsiveness, hostility, cognitive support, and physical presence. Each dimension was uniquely associated with perceived benefits of receiving interpersonal emotion regulation. In Study 2, we collected multiple, diverse samples (ns = 199-895) and found support for the replicability and generalizability of key findings from Study 1, including the factor structure and associations with perceived benefits. In summary, across 2 studies and multiple, diverse samples, we identified 4 conceptually and practically important dimensions of receivers' evaluations of interpersonal emotion regulation interactions and developed a brief measure that taps interaction variability in these dimensions.

Emotion-related impulsivity and rumination: Unique and conjoint effects on suicidal ideation, suicide attempts, and nonsuicidal self-injury across two samples.

INTRODUCTION: Rumination and emotion-related impulsivity predict suicidal ideation, suicide attempts, and nonsuicidal self-injury (NSSI). Because rumination and emotion-related impulsivity, though, are highly correlated, we consider their unique vs. conjoint influence on suicidal ideation and self-harm. METHOD: Across two samples of adults (N's = 171 and 191), we examined how rumination and emotion-related impulsivity relate to suicidal ideation, suicide attempts, and NSSI. We assess the more general process of repetitive negative thinking and the more specific process of suicide-related rumination. Participants completed the Three-Factor Impulsivity Index and the self-report Columbia-Suicide Severity Rating Scale. Those in sample 1 completed the Perseverative Thinking Questionnaire and the Deliberate Self-Harm Inventory, and those in Sample 2 completed the Suicide Rumination Scale. RESULTS: Emotion-related impulsivity and both forms of rumination showed robust bivariate correlations with suicidal ideation, suicide attempts, and NSSI. Neither rumination or impulsivity related to suicide attempts controlling for ideation or to NSSI. In multivariable analyses, emotion-related impulsivity but not general rumination was tied to suicidal ideation. In contrast, suicide-related rumination was more directly tied to suicidal ideation than was impulsivity. CONCLUSIONS: Findings provide support for a more nuanced approach to the forms of impulsivity and rumination related to suicidal ideation.

Momentary Emotion Goals and Spontaneous Emotion Regulation in Daily Life: An Ecological Momentary Assessment Study of Desire for High Versus Low Arousal Positive Emotion.

Recent research has highlighted that emotion regulation strategy use varies both between and within people, and specific individual and contextual differences shape strategy use. Further, use of specific emotion regulation strategies relates to a wide array of differential outcomes, including mental health and behavior. Emotion goals (desire for a given emotion state) are thought to play a particularly important role in shaping people's use of emotion regulation strategies; yet, surprisingly little is known about whether and how momentary emotion goals predict spontaneous strategy use in daily life. In the present investigation, we examined whether ideal desire for high versus low arousal positive affect was associated with subsequent use of specific emotion regulation strategies. Undergraduate participants (final N = 101) completed ecological momentary assessments (final ks = 1,932 for contemporaneous analyses, 1,386 for time-lagged analyses) of their momentary experienced affect, momentary desire for high versus low arousal positive affect, and emotion regulation. Desire for higher arousal predicted greater use of three disengagement strategies: distraction, expressive suppression, and experiential suppression. None of these strategies, though, were associated with sustained enhancement of high arousal (or low arousal) positive affect. These findings point to a possible disconnect between the strategies that people tend to use when they want to feel more arousal and the affective outcomes associated with use of those strategies.

Social dominance and multiple dimensions of psychopathology: An experimental test of reactivity to leadership and subordinate roles.

BACKGROUND: Theory and research suggest that social dominance is important for multiple forms of psychopathology, and yet few studies have considered multiple dimensions of psychopathology simultaneously, and relatively few have used well-validated behavioral indices. METHOD: Among 81 undergraduates, we used a well-validated experimental approach of assigning participants to a leadership or subordinate position, and we examined how self-rated severity of depression, social anxiety, manic tendencies, and psychopathy relate to psychophysiological and affective reactivity to this role. RESULTS: Consistent with hypotheses, manic symptoms related to more discomfort in the subordinate role compared to the leadership role, as evidenced by more decline in positive affect, more discomfort, and a larger RSA decline, while depression symptoms related to a more positive response to the subordinate role than the leadership role, including more positive affect and more comfort in the assigned role. Social anxiety was related to discomfort regardless of the assigned role, and those with higher psychopathy symptoms did not show differential response to assigned roles. LIMITATIONS: Findings are limited by the mild symptom levels and absence of hormonal data. CONCLUSIONS: Findings provide novel transdiagnostic evidence for the importance of social dominance to differentiate diverse forms of psychopathology.

Longitudinal associations between internalizing symptoms, social behavior, and social perceptions in the initial months of the COVID-19 pandemic: Findings from a transdiagnostic community sample.

BACKGROUND: Burgeoning evidence suggests that loneliness during the COVID-19 pandemic is tied to high levels of depression and anxiety. The current study is unique, though, in examining which facets of social behavior and perceived social quality are most tied to internalizing symptoms using longitudinal data, including a pre-pandemic baseline, collected from a community sample of adults with pre-existing mental health concerns (analyzed n = 144). METHODS: Participants completed measures of depressive and anxious symptoms pre-pandemic, followed by three weekly surveys during the pandemic. We distinguished four social variables: in-person social engagement, remote social engagement, social disruption, and social distress. OLS and mixed-effects regression models examined 1) pre-pandemic baseline symptoms as predictors of social functioning during the pandemic and 2) time-lagged associations between symptoms and social functioning during the pandemic. RESULTS: Social behavior and social perceptions were dissociable. Baseline depressive, but not anxious, symptoms predicted greater social distress during the pandemic. Both anxious and depressive symptoms were predicted by social variables, but the specific associations differed: depressive symptoms were related to perceived social quality, whereas anxious symptoms were more tied to reported social behavior. LIMITATIONS: We relied on self-report indices, and causality should not be inferred directly from these correlational data. CONCLUSIONS: Overall, our results indicate that it is possible to follow social guidelines and even to spend relatively few hours socializing with close others, while still feeling connected and rewarded; however, people who struggle with depression and anhedonia were particularly vulnerable to distressing feelings of social disconnection amid the pandemic.

Maladaptive behavior and affect regulation: A functionalist perspective.

Clinical science has benefited tremendously from taking seriously the proposition that putatively maladaptive behaviors serve psychological functions, prominently among these affect regulation (AR). These functionalist accounts have not only advanced basic clinical science, but also formed the bedrock for the development of effective treatments. Drawing heavily on reinforcement learning theory, we aim to elucidate functional relationships between maladaptive behavior and AR. Specifically, we take the view that maladaptive behaviors are frequently motivated and reinforced by hedonic AR functions (i.e., decreasing negative affect and increasing positive affect) but are also susceptible to becoming stimulus-bound habits. We review empirical evidence related to one such behavior, nonsuicidal self-injury. We close with a brief reflection on future directions.

Development of a brief online intervention to address aggression in the context of emotion-related impulsivity: Evidence from a wait-list controlled trial.

Trait-like tendencies to respond impulsively to emotion, labelled emotion-related impulsivity, are robustly related to aggression. We developed and tested an online intervention to address emotion-related impulsivity and aggression. The 6-session intervention focused on behavioral techniques shown to decrease arousal and aggression, supplemented with implementation intentions and smartphone prompts to facilitate skills transfer into daily life. First, we piloted the intervention in-person with 4 people. Then, 235 participants were randomly assigned to take the online intervention immediately or after a wait-list period; those in the waitlist were then invited to take part in the intervention. Participants completed the self-rated Feelings Trigger Action Scale to assess emotion-related impulsivity, the interview-based Modified Overt Aggression Scale and the self-rated Buss Perry Aggression Questionnaire. Participants who took part in the treatment completed daily anger logs. Attrition, as with other online programs, was high; however, treatment completers reported high satisfaction, and outcomes changed more rapidly during treatment than waitlist across all key outcome indices. In analyses including all participants who took part in the treatment (immediate or delayed), we observed moderate-to-large treatment gains, which were maintained as of the 3-month follow-up assessment. This work supports the usefulness of an intervention for addressing emotion-related impulsivity and aggression.

A brief online intervention to address aggression in the context of emotion-related impulsivity for those treated for bipolar disorder: Feasibility, acceptability and pilot outcome data.

Although aggression is related to manic symptoms among those with bipolar disorder, new work suggests that some continue to experience elevations of aggression after remission. This aggression post-remission appears related to a more general tendency to respond impulsively to states of emotion, labelled emotion-related impulsivity. We recently developed the first intervention designed to address aggression in the context of emotion-related impulsivity. Here, we describe feasibility, acceptability, and pilot data on outcomes for 21 persons who received treatment for bipolar disorder and endorsed high levels of aggression and emotion-related impulsivity. As with other interventions for aggression or bipolar disorder, attrition levels were high. Those who completed the intervention showed large changes in aggression using the interview-based Modified Overt Aggression Scale that were sustained through three months and not observed during wait list control. Although they also showed declines in the self-rated Buss-Perry Aggression Questionnaire and in self-rated emotion-related impulsivity as assessed with the Feelings Trigger Action Scale, these self-ratings also declined during the waitlist control. t Despite the limitations, the findings provide the first evidence that a brief, easily disseminated intervention could have promise for reducing aggression among those with bipolar disorder.

Working memory interacts with emotion regulation to predict symptoms of mania.

Although neurocognitive deficits and emotion regulation are closely linked within unipolar depression, little research has tested links between these two variables within bipolar disorder. The present study tested whether working memory is related to individual differences in emotion regulation strategies in bipolar disorder and whether working memory and emotion regulation can explain variability in symptoms over time. Fifty-nine euthymic adults with bipolar I disorder completed a working memory span task, symptom interviews assessing depression and mania, and questionnaires assessing brooding rumination, reappraisal, and suppression. At baseline, working memory was unrelated to emotion regulation. Symptom interviews were repeated at six months (n = 41) and 12 months (n = 36) follow-up. At 12 months, baseline working memory significantly interacted with baseline suppression to predict higher mania. Tests of simple slopes showed that at lower working memory levels, low use of suppression was associated with significantly greater mania symptoms. These results help to clarify previous inconsistent findings regarding cognitive functioning and emotion regulation strategies in bipolar disorder, suggesting that deficits in both domains combine to predict outcomes.

Multivariate associations of ideal affect with clinical symptoms.

Prior research has indicated that ideal affect (i.e., the affective states that people value and would ideally like to experience) may be relevant to mental health outcomes. Studies to date, however, have not used comprehensive multivariate models that account for covariation among facets of ideal affect and incorporate multiple clinical outcomes. In the present studies, we used structural equation modeling to examine the multivariate effects of ideal affect on symptoms of depression, anxiety, and alcohol abuse in 2 moderately large samples of undergraduates (N = 293 and N = 146). Exploratory results of Study 1 indicated that valuation of high arousal positive affective states was significantly associated with lower depression symptoms but higher anxiety and alcohol abuse symptoms and that valuation of high arousal negative states was specifically associated with greater anxiety symptoms. These results were shown to be structurally invariant across samples and ethnicities in Study 2, which also found that ideal-actual affect discrepancies were significantly associated with symptoms of depression and anxiety. These findings support and extend the hypothesis that ideal affect is implicated in clinical outcomes by highlighting the importance of jointly considering multiple facets of ideal and actual affect as they relate to a range of clinical syndromes.

Defect-induced loss mechanisms in polymer-inorganic planar heterojunction solar cells.

The effect of ZnO defects on photoexcited charge carrier recombination and forward induced charge transfer was studied in organic-inorganic bilayer organic heterojunction solar cells. Decreased bimolecular recombination via passivation of ZnO nanopariticle defects resulted in longer carrier lifetime as determined by transient photovoltage (TPV) measurements. It was also found by time-resolved photoluminescence (TRPL) measurements that defect passivation decreased the fluorescence lifetime which indicated higher exciton dissociation efficiency. Through passivation of the ZnO nanoparticles defects, the two loss mechanisms were reduced and the power conversion efficiency (PCE) is significantly enhanced.
