Daily Associations Between Injunctive Drinking Norms and Alcohol Consumption.

OBJECTIVE: Perception of others' approval of alcohol use (i.e., injunctive drinking norms) is strongly predictive of alcohol use, particularly among young adults (Krieger et al., 2016). While between-person injunctive norms predict alcohol use (Neighbors et al., 2008), there is evidence of within-person fluctuations in the relationship between norms and drinking (Graupensperger et al., 2021). The current study used ecological momentary assessment (EMA) to test within-person, day-level associations between injunctive norms and alcohol use, and to test whether social context moderated this association. METHOD: Participants (n=83, M age=24.0, 50.9% female) completed a two-week EMA protocol using a smartphone application. Injunctive norms, social context (type and gender of companions), and number of drinks consumed were assessed each morning following a drinking event. Multilevel models with repeated measures nested within participants tested main effects and interactions of between- and within-person injunctive norms, type of drinking companions, and gender of drinking companions on number of drinks consumed. RESULTS: Day-level injunctive norms were positively associated with drinking quantity over and above baseline norms. The effect of norms differed by social context such that norms were only positively related to drinking quantity when drinking with a friend or romantic partner (vs. drinking alone). Gender of friends with whom participants drank did not moderate the effect of norms on quantity. CONCLUSIONS: This study provides one of the first examinations of daily fluctuations in injunctive drinking norms. As norms represent a malleable target for intervention (White et al., 2019), results offer new information regarding possible intervention targets.

Development and Initial Validation of a Momentary Cannabis Craving Scale Within a Homogeneous Sample of U.S. Emerging Adults.

Given the popularity and ease of single-item craving assessments, we developed a multi-item measure and compared it to common single-item assessments in an ecological momentary assessment (EMA) context. Two weeks of EMA data were collected from 48 emerging adults (56.25% female, 85.42% White) who frequently used cannabis. Eight craving items were administered, and multilevel factor analyses were used to identify the best fitting model. The resulting scale's factors represented purposefulness/general desire and emotionality/negative affect craving. Convergent validity was examined using measures of craving, cannabis use disorder symptoms, frequency of use, cannabis cue reactivity, cannabis use, negative affect, and impulsivity. The scale factors were associated with cue-reactivity craving, negative affect, impulsivity, and subfactors of existing craving measures. For researchers interested in using a single item to capture craving, one item performed particularly well. However, the new scale may provide a more nuanced assessment of mechanisms underlying craving.

Trait impulsivity moderates rate of alcohol consumption in daily life.

INTRODUCTION: Rate of alcohol consumption, the speed with which people drink, has been linked to a range of outcomes, including alcohol use disorder symptoms and increased positive affect. However, minimal work has identified who is most likely to drink at elevated rates. Impulsivity is associated with increased attention to positive reinforcers specifically (e.g., positive affect). We therefore examined whether people higher in trait impulsivity engage in faster consumption during drinking episodes. METHODS: Participants were current drinkers (N = 113; 54 people with borderline personality disorder [BPD], a disorder that involves elevated impulsivity, and 59 community people) who completed a 21-day ecological momentary assessment (EMA) protocol. Multilevel models of drinking episodes (Nobservations = 3,444) examined whether self-reported trait impulsivity, measured at baseline, was associated with faster rise in estimated blood alcohol concentration (eBAC) at each follow-up period. RESULTS: All UPPS sub-scales were associated with faster rise in eBAC across a drinking episode. In a multivariate model including all sub-scales as simultaneous predictors, sensation seeking and (lack of) perseverance were independently positively associated with rate of consumption. Additional analyses indicated that greater negative urgency and sensation seeking were associated with faster rises in eBAC in participants with BPD, relative to community comparisons. CONCLUSION: In a sample that captured a wide spectrum of impulsivity, greater impulsivity was associated with drinking alcohol at a faster rate. People higher in sensation seeking and (lack of) perseverance may be prone to drink at faster rates out of a desire to maximize the hedonic effects of alcohol. PUBLIC SIGNIFICANCE STATEMENT: This study finds that people who are more impulsive tend to drink alcohol faster, putting them at greater risk for negative consequences. This may explain, in part, why impulsivity is linked to experiencing alcohol-related problems.

The Brief Emotion Dysregulation Scale: Development, Preliminary Validation, and Recommendations for Use.

Emotion dysregulation is a multi-faceted, transdiagnostic construct, and its assessment is crucial for characterizing its role in the development, maintenance, and treatment of psychiatric problems. We developed the Brief Emotion Dysregulation Scale (BEDS) to capture four components of emotion dysregulation: sensitivity, lability, reactivity, and consequences. We examined factor structure and construct validity in four independent samples of college students (N = 1,485). We elected to treat consequences as a separate index of problems associated with emotion dysregulation. Exploratory and confirmatory factor analyses did not support the reactivity subscale and instead supported a well-fitting two-factor solution for sensitivity and lability. Multi-group analyses demonstrated strong factorial invariance by gender. The resulting 12-item BEDS includes sensitivity and lability subscales and a separate consequences scale to indicate associated problems. Convergent correlations suggested good construct validity. This provides preliminary support for the BEDS as a brief transdiagnostic screening tool for emotion dysregulation and associated consequences.

Using mobile technology to influence alcohol-impaired driving risk perceptions and decisions.

OBJECTIVE: Despite significant individual and societal risk, alcohol-impaired driving (AID) remains prevalent in the United States. Our aim was to determine whether breathalyzer-cued warning messages administered via mobile devices in the natural drinking environment could influence real-world AID cognitions and behaviors. METHOD: One hundred twenty young adults (53% women; mean age = 24.7) completed 6 weeks of ecological momentary assessment (EMA) and provided breathalyzer samples using a BACtrack Mobile Pro linked to their mobile device. On mornings after drinking episodes, participants reported their driving activities from the previous evening (787 episodes). Participants were randomly assigned to receive warning messages if they reached a breath alcohol concentration (BrAC) ≥ .05, or no messages. Participants in the warnings condition reported their willingness to drive and perceived danger of driving at EMA prompts (1,541 reports). RESULTS: We observed a significant effect of condition, such that the association between cumulative AID engagement and driving after reaching a BrAC of .05 was dampened among individuals in the warnings condition, compared to those in the no warnings condition. Receiving a warning message was associated with increased momentary perceived danger of driving and decreased willingness to drive. CONCLUSIONS: We found that BrAC-cued warning messages reduced the probability of AID and willingness to drive while impaired, and increased the perceived danger of driving after drinking. These results serve as proof-of-concept for the use of mobile technology to deliver an adaptive just-in-time intervention to reduce the probability of AID.

Momentary impulsivity interferes with emotion regulation strategy prioritization in everyday life in remitted depression.

BACKGROUND: Selectively prioritizing some emotion regulation (ER) strategies over others has been shown to predict well-being; however, it is unclear what mechanisms underlie this process. Impulsivity, which captures both top-down control of and bottom-up reactivity to emotions, is one potential mechanism of interest. METHODS: Using multilevel mediation modeling, we investigated whether lower ER strategy prioritization (i.e., lower between-strategy variability) mediates the relationship between greater momentary impulsivity and lower ER success in 82 individuals with remitted depression or no history of a mental disorder (1558 observations). To determine the specific effect of impulsivity, we covaried for mean regulatory effort and negative affect. RESULTS: The indirect effect of impulsivity on ER success was significant at the within-person, but not between-person, level. Specifically, in moments when individuals endorsed more impulsivity than usual, they showed less ER strategy prioritization than usual, which predicted less successful ER. Individuals who, on average, reported more impulsivity indicated lower ER strategy prioritization, but no difference in ER success. CONCLUSION: ER strategy prioritization mediated the within-person relationship between greater impulsivity and lower ER success. Interventions focused on training individuals to selectively prioritize ER strategies may improve ER success, particularly when individuals are feeling more impulsive than usual.

Predicting quantity of cannabis smoked in daily life: An exploratory study using machine learning.

BACKGROUND: Cannabis use is prevalent in the United States and is associated with a host of negative consequences. Importantly, a robust indicator of negative consequences is the amount of cannabis consumed. METHODS: Data were obtained from fifty-two adult, regular cannabis flower users (3+ times per week) recruited from the community; participants completed multiple ecological momentary assessment (EMA) surveys each day for 14 days. In this exploratory study, we used various machine learning algorithms to build models to predict the amount of cannabis smoked since participants' last report including forty-three EMA measures of mood, impulsivity, pain, alcohol use, cigarette use, craving, cannabis potency, cannabis use motivation, subjective effects of cannabis, social context, and location in daily life. RESULTS: Our best-fitting model (Gradient Boosted Trees; 71.15% accuracy, 72.46% precision) found that affects, subjective effects of cannabis, and cannabis use motives were among the best predictors of cannabis use amount in daily life. The social context of being with others, and particularly with a partner or friend, was moderately weighted in the final prediction model, but contextual items reflecting location were not strongly weighted in the final prediction model, the one exception being not at work. CONCLUSIONS: Machine learning approaches can help identify additional environmental and psychological phenomena that may be clinically-relevant to cannabis use.

Pain before, during, and after nonsuicidal self-injury: Findings from a large web study.

Competing models suggest that physical pain may play an important role in nonsuicidal self-injury (NSSI) via pain onset or pain offset, or that pain may be absent (analgesia). Few studies have tested these models in the same sample or examined factors that could explain differences in NSSI pain experience. We assessed 1,630 individuals with NSSI histories in an online survey. We descriptively examined pain during NSSI and tested preregistered hypotheses that NSSI frequency, NSSI severity, borderline personality disorder (BPD) features, emotional pain, and dissociation during NSSI are associated with experiencing less NSSI pain. Exploratorily, we also tested whether self-punishment motives were associated with less NSSI pain. Almost all participants reported recent and frequent NSSI. Participants were heterogenous in their report of NSSI pain. We found minimal support for analgesia (reported by only 4.3% of participants). More participants reported pain onset than offset, but offset was associated with reductions in emotional pain. Emotional pain was elevated prior to NSSI and decreased significantly during and after NSSI. We found that higher dissociation during NSSI was associated with less NSSI pain. Contrary to hypotheses, NSSI severity, emotional pain prior to NSSI, and self-punishment motives were associated with greater NSSI pain. NSSI frequency and BPD features were not associated with NSSI pain. BPD features interacted with dissociation and emotional pain prior to NSSI. Findings contrast with laboratory pain induction work, suggesting that, though people who self-harm may have heightened pain tolerance, they may seek to self-injure in a manner that results in pain.

Autonomic complexity dynamically indexes affect regulation in everyday life.

Affect regulation often is disrupted in depression. Understanding biomarkers of affect regulation in ecologically valid contexts is critical for identifying moments when interventions can be delivered to improve regulation and may have utility for identifying which individuals are vulnerable to psychopathology. Autonomic complexity, which includes linear and nonlinear indices of heart rate variability, has been proposed as a novel marker of neurovisceral integration. However, it is not clear how autonomic complexity tracks with regulation in everyday life, and whether low complexity serves as a marker of related psychopathology. To measure regulation phenotypes with diminished influence of current symptoms, 37 young adults with remitted major depressive disorder (rMDD) and 28 healthy comparisons (HCs) completed ambulatory assessments of autonomic complexity and affect regulation across one week in everyday life. Multilevel models indicated that in HCs, but not rMDD, autonomic complexity fluctuated in response to regulation cues, increasing in response to reappraisal and distraction and decreasing in response to negative affect. Higher complexity across the week predicted greater everyday regulation success, whereas greater variability of complexity predicted lower (and less variable) negative affect, rumination, and mind-wandering. Results suggest that ambulatory assessment of autonomic complexity can passively index dynamic aspects of real-world affect and regulation, and that dynamic physiological reactivity to regulation is restricted in rMDD. These results demonstrate how intensive sampling of dynamic, nonlinear regulatory processes can advance our understanding of potential mechanisms underlying psychopathology. Such measurements might inform how to test interventions to enhance neurovisceral complexity and affect regulation success in real time. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Dynamic relations among simultaneous alcohol and cannabis use, subjective responses, and problem drinking during naturally occurring drinking episodes.

BACKGROUND: Simultaneous alcohol and cannabis use (SAM) is associated with riskier drinking. However, little is known regarding mechanisms of risk during drinking episodes. The current study tested whether subjective responses to simultaneous vs. alcohol-only use (i.e., high arousal positive/reward, high arousal negative/aggression, low arousal positive/relaxation, low arousal negative/impairment) were mechanisms through which SAM use was associated with daily drinking. METHODS: Emerging adults who co-use alcohol and cannabis (N=85) completed 21 days of ecological momentary assessment with drink-contingent reports during drinking episodes. Participants reported on their simultaneous use and current subjective effects during drink reports and past-night total drinks consumed and negative consequences experienced the next morning. Three-level multilevel models (momentary, daily, person level) tested whether SAM use predicted subjective responses, and whether subjective responses mediated associations between SAM use, heavier drinking and negative consequences. RESULTS: At the momentary and day-level, SAM (vs. alcohol-only) use predicted increased high arousal positive/rewarding, low arousal positive/relaxing, and low arousal negative/impairing subjective effects. SAM use indirectly predicted heavier day-level drinking and further negative consequences through high arousal positive/rewarding response. SAM use also indirectly predicted day-level negative consequences through low arousal negative/impairing response. At the person-level, more frequent SAM use predicted higher person-average high arousal positive/rewarding and low arousal positive/relaxing responses, and high arousal positive/rewarding response mediated relation between SAM frequency and heavier drinking. CONCLUSIONS: Simultaneous use was associated with reward, relief, and impairment, and reward and impairment were mechanisms of risk between SAM use and riskier drinking. Findings may inform theory and just-in-time interventions seeking to reduce alcohol misuse.

Measuring affect in daily life: A multilevel psychometric evaluation of the PANAS-X across four ecological momentary assessment samples.

While there is strong evidence for the psychometric reliability of the Positive and Negative Affect Schedule-Expanded Form (PANAS-X) in cross-sectional studies, the between- and within-person psychometric performance of the PANAS-X in an intensive longitudinal framework is less understood. As affect is thought to be dynamic and responsive to context, this study investigated the multilevel reliability of PANAS-X Positive Affect, Negative Affect, Fear, Sadness, and Hostility scales. Generalizability theory and structural equation modeling techniques (coefficient ω) were employed in four ecological momentary assessment samples (N = 309; 41,261 reports). Results demonstrate that the PANAS-X scales, including short versions of the Positive and Negative Affect scales, can reliably detect between-person differences. PANAS-X scales also were able to reliably measure within-person change, though these estimates may be impacted by scale content and study design. These results support the use of the PANAS-X in daily life research to intensively measure affect in the natural environment. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Implementing an EMA burst design in community-engaged research: participant and researcher perspectives and recommendations.

Background: Implementing ecological momentary assessment (EMA) methodology to evaluate the substance use disorder (SUD) treatment pipeline has clear advantages, including learning about participants' day-to-day experiences to aid in the improvement of services and accessibility for those seeking treatment. Given that the SUD treatment pipeline spans long periods of time, EMA burst designs (deployment of multiple short EMA periods spread over time) can be advantageous for evaluating the treatment pipeline over time while keeping participant burden low.Objectives: This feasibility study describes (1) the process and study design of implementing EMA burst methodology to evaluate the SUD treatment pipeline experience; (2) study implementation from the perspective of researchers, including discussion of collaboration with community partners; and (3) participant feedback on the experience of engaging with this type of research.Method: EMA metrics, feasibility ratings, and general experience ratings in the study are presented from 22 participants (64% women) who participated in a parent EMA study evaluating the SUD treatment pipeline and 8 who provided feedback in a follow-up survey.Results: Participants found the EMA burst design to be acceptable and not burdensome, although technology issues were present for some participants. Steps to partnering with community treatment programs and implementation of a burst design are outlined.Conclusions: Strategies and recommendations for implementation of an EMA burst study with community partners are provided, including aspects of study design, technology issues, retention, and funding.

Agreement between momentary and retrospective reports of cannabis use and alcohol use: Comparison of ecological momentary assessment and timeline followback indices.

OBJECTIVE: This study compares three methods of cannabis and of alcohol use assessment in a sample of regular cannabis users: (a) ecological momentary assessment (EMA) repeated momentary surveys aggregated to the daily level, (b) EMA morning reports (MR) where participants reported on their total use from the previous day, and (c) retrospective timeline followback (TLFB) interviews covering the same period of time as the EMA portion of the study. We assessed the overall correspondence between these methods in terms of cannabis and alcohol use occasions and also investigated predictors of agreement between methods. METHOD: Forty-nine individuals aged 18-50 (Mage = 24.49, 49% female, 84% White) who reported regular cannabis use completed a 14-day EMA study. At the end of the EMA period, participants returned to the laboratory to complete a TLFB (administered via computer) corresponding to the same dates of the EMA period. RESULTS: Daily aggregated EMA and TLFB reports showed a low to modest agreement for both alcohol and cannabis use. Overall, agreement between EMA and MR was better than agreement between EMA and TLFB, likely because less retrospection is required when only reporting on behavior from the previous day. Quantity and frequency of use differentially predicted agreement across reporting methods when assessing alcohol compared to cannabis. When reporting cannabis use, but not alcohol use, individuals who used more demonstrated higher agreement between EMA and TLFB. CONCLUSIONS: Results suggest that retrospective reporting methods assessing alcohol and cannabis should not be considered a direct "substitute" for momentary or daily assessments.

Operationalizing undifferentiated affect: Validity and utility in clinical samples.

Emotion differentiation is conceptualized as the process of categorizing one's general affective experiences into discrete emotions. The experience of undifferentiated affect or the inability to distinguish the particular emotion or combination of emotions that one is experiencing is often considered a hallmark of emotion dysregulation. Some past research has attempted to operationalize the general tendency to experience undifferentiated affect at the trait level using explicit questionnaire measures. More recently, indirect measures using intraclass correlation coefficients (ICCs) to estimate the consistency between simultaneous measures of different in-the-moment emotional experiences have become the favored method of quantifying undifferentiated affect. While the ICC method constitutes an advancement in estimating undifferentiated affect, which is theorized to be a dynamic process that occurs at a very granular level, prior investigations have used aggregate ICC measures or momentary ICC derivations that ignore multiple sources of dynamic variability to make inferences about in-the-moment experiences. We introduce a new, flexible method of calculating ICC measures of undifferentiated affect at different levels of experience that takes full advantage of time-intensive data measurement and more closely maps onto the theorized process. This method provides more refined estimates of undifferentiated affect and its associations with various behavioral outcomes, as well as uncovers more nuanced associations regarding the temporal process of emotional differentiation. It also elucidates potential conceptual issues in mapping empirical estimates of emotion undifferentiation onto their underlying theoretical interpretations.

Momentary subjective responses to alcohol as predictors of continuing to drink during daily-life drinking episodes.

PURPOSE: Subjective response to alcohol's stimulating and sedating effects is a person-level risk factor for heavy drinking and alcohol use disorder. Longitudinal and laboratory studies have demonstrated that at-risk individuals experience greater stimulation and lower sedation while drinking. While between-person subjective responses inform risk and etiology, in-the-moment assessments during daily-life drinking may elucidate the within-person processes by which stimulation and sedation may lead to heavier drinking. We aimed to characterize these momentary processes by testing momentary stimulation and sedation during drinking as predictors of subsequently continuing to drink during densely sampled, daily-life drinking episodes. PROCEDURES: 113 adults (54 with borderline personality disorder and 59 community participants; 77.9% female) completed ecological momentary assessment for 21 days, reporting momentary subjective stimulation and sedation throughout drinking episodes and momentary alcohol use after drink initiation (i.e., continued drinking). FINDINGS: GLMMs demonstrated that greater day-level stimulation (OR=1.48, 95% CI=[1.20, 1.82], p<.001), greater person-level stimulation (OR=1.63, 95% CI=[1.05, 2.53], p=.031), and lower momentary sedation (OR=0.54, 95% CI=[0.41, 0.71], p<.001) predicted continued drinking. CONCLUSIONS: Although greater stimulation and lower sedation have been conceptualized as individual-level risk factors for heavy drinking, our findings suggest that these associations are accompanied by processes that operate within person. Our results suggest that greater stimulation may confer risk for heavy drinking at the level of the drinking episode, possibly acting as positive reinforcement that may contribute to heavier drinking during future episodes. In contrast, lower sedation may primarily confer in-the-moment risk by contributing to momentary decisions to keep drinking within an episode.

Using ecological momentary assessment and a portable device to quantify standard tetrahydrocannabinol units for cannabis flower smoking.

AIMS: To evaluate the feasibility and validity of a new method of quantifying cannabis flower use, integrating the amount of cannabis flower smoked, and the potency of the cannabis flower. DESIGN: Ecological momentary assessment (EMA) for 14 days. SETTING: Participants' daily lives in Columbia, Missouri, USA. PARTICIPANTS: A total of 50 community participants, who were regular cannabis flower smokers (48% female). MEASUREMENTS: Momentary subjective intoxication ratings following cannabis flower smoking; momentary quantity of cannabis flower smoked; potency of cannabis flower smoked in terms of percentage of tetrahydrocannabinol (THC) concentration assessed with a portable device, the Purpl Pro; and time since finished smoking. FINDINGS: Participants completed our field testing of their cannabis flower (96.2%) and were compliant with our 2-week EMA protocol (73% for random prompts and 91% for morning reports). Momentary subjective intoxication ratings trended down as a function of time since smoking (r = -0.10, P = 0.004, 95% CI, [-0.17, -0.03]). Multi-level model (MLM) results indicated the momentary standard THC units (mg THC) were positively associated with momentary subjective intoxication ratings (b = 0.01, P = 0.03, 95% CI, [0.01, 0.012]). CONCLUSIONS: There is evidence to support the feasibility and initial validity of a new method of quantifying cannabis flower use into standard tetrahydrocannabinol units. Researchers investigating the effects of cannabis flower use on a range of outcomes (e.g. neurobehavioral effects, emotional sequelae, and driving impairment) as well as in clinical treatment trials might adopt this method to provide estimates of cannabis flower use.

Comparing associations between mood and breath alcohol concentration in the laboratory and natural environment.

OBJECTIVE: Associations between mood and drinking are part of many theoretical models of problematic alcohol use. Laboratory and ecological momentary assessment (EMA) research on associations between mood and drinking behavior has produced mixed findings, and these constructs are often measured using different methods depending on research context. The present study compares associations between mood and alcohol consumption across research contexts (laboratory vs. daily life) and measurement methods (breathalyzer vs. self-report). METHOD: Forty-five young adults (53% women, Mage = 24.5) who drank moderate-to-heavy amounts completed an alcohol administration session and then 6 weeks of EMA with ambulatory breathalyzer samples. Participants reported their current mood (happy, nervous, upset, and excited) in both the laboratory and during EMA. Momentary, day, and person-level mood variables were examined in multilevel models predicting objective alcohol consumption [breath alcohol concentration (BrAC); lab and EMA] and subjective consumption (self-reported drinking occurrence and number of drinks; EMA). RESULTS: We identified discrepant mood-BrAC associations across laboratory and EMA contexts. Momentary excitement was negatively associated with BrAC in the lab, but positively associated with BrAC during EMA (ps < .01). We also identified discrepancies within EMA depending on the alcohol consumption measure used (BrAC or self-reported number of drinks) and the level of analysis (momentary or day). CONCLUSIONS: Studies testing theoretical models involving directional mood-alcohol associations (e.g., affective reinforcement models) need to carefully consider how research context and methods may influence findings of associations between mood and drinking.

Relations between lab indices of emotion dysregulation and negative affect reactivity in daily life in two independent studies.

BACKGROUND: We investigated the extent to which physiological/biological measures of emotion dysregulation collected in the lab, resting respiratory sinus arrhythmia (RSA) in Study 1 and amygdala activation in response to negative stimuli in Study 2, combined with daily measures of interpersonal stressors predicted negative emotional states in outpatients better than the stressors alone. METHODS: Participants were adult outpatients with emotional distress disorders (N=30 individuals in Study 1, and N=26 women in Study 2). After completing a laboratory session that collected physiological/biological measures of emotion dysregulation, participants then completed 1-3 weeks of ambulatory assessment during which they reported on interpersonal stressors and negative affective states several times per day. RESULTS: Laboratory measures of emotion dysregulation were largely unrelated to either momentary or mean levels of daily-life hostility, sadness, and fear in both studies. However, resting RSA significantly moderated the association between day-level interpersonal stressors and momentary fear such that low resting RSA strengthened this association. Similarly, amygdala activation tended to moderate this relationship in the predicted direction. LIMITATIONS: Both samples were relatively small and focused on only a limited set of diagnoses associated with emotion dysregulation. Only two possible physiological/biological markers of emotion dysregulation were examined. CONCLUSIONS: The current studies support the collection of physiological/biological data on emotion dysregulation when indexing daily-life emotion dysregulation as the degree of emotional reactivity to stressors in daily life among outpatients with emotional distress disorders.

The roles of personality traits and close social contact in the expression of momentary borderline personality disorder symptoms in daily life.

Dimensional models of personality, such as the five-factor model (FFM), have demonstrated strong coherence with the presentation of personality disorders, including borderline personality disorder (BPD). Given that select personality trait elevations have been linked to impairments in multiple life domains across diagnostic groups, we sought to replicate findings from a previous investigation of the utility of the FFM in predicting BPD-relevant outcomes (i.e., negative affect intensity and instability, impulsivity, and interpersonal disagreements) in the daily lives of those with BPD (Hepp et al., 2016) and community participants. As interpersonal context is instrumental in determining the strength of effects observed in studies examining individuals with BPD, we utilized ecological momentary assessment across 3 weeks (6 times daily; ntotal = 15,889) to test whether close social contact (CSC) would moderate the effects of personality on momentary outcomes. Overall, results suggest that CSC is an important moderator between the effects of personality and daily life outcomes for individuals with BPD (N = 56), but not for community individuals (N = 60). For individuals with BPD, CSC may function as both a protective buffer and a risk factor, depending on outcome. For example, CSC attenuates experience of negative affect intensity for individuals with elevated neuroticism, but CSC may predict more frequent disagreements for individuals who report lower agreeableness. We replicated approximately half of the original study's findings, and results support that FFM personality is predictive of BPD-relevant outcomes broadly. However, interpersonal context is key to understanding these relationships for individuals with BPD. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

The influence of narcissistic vulnerability and grandiosity on momentary hostility leading up to and following interpersonal rejection.

Wide empirical support exists for 2 aspects of narcissism-grandiosity and vulnerability. Hostility is a form of interpersonal antagonism, which is considered central to narcissism broadly. Though it has often been subsumed by the concept of narcissistic grandiosity, interpersonal antagonism is associated with vulnerability as well. Rejection represents an interpersonal stressor that evokes hostility to a greater degree in those high in narcissism, with mixed evidence regarding whether it stems from threat to one's egotism (grandiosity) or low self-esteem (vulnerability). Therefore, investigating the associations between narcissistic dimensions and individuals' trajectories of hostility leading up to and following rejection may provide a basis for a more unified conceptualization. In this study, we leverage the wide range of narcissistic expression displayed in a combined sample of borderline personality disorder (N = 56) and community (N = 60) individuals who completed ambulatory assessments approximately 6 times per day for 21 consecutive days. We examine whether narcissistic vulnerability and grandiosity, as measured by NEO Personality Inventory facet combinations constructed based on the Five-Factor Narcissism Inventory, moderate trajectories and overall levels of hostility surrounding self-reported interpersonal rejections. Grandiosity and vulnerability were independently positively associated with a faster rise in hostility leading up to rejection; however, greater grandiosity was uniquely associated with a greater spike in hostility at the occasion of rejection and subsequent faster recovery. These results are consistent with both the idea that grandiosity is proportionately more central to interpersonal antagonism and that antagonism serves as a bridge, connecting and reinforcing both narcissistic grandiosity and vulnerability.
