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.

Momentary assessment of the relations between narcissistic traits, interpersonal behaviors, and aggression

INTRODUCTION

This study explores the associations among narcissistic traits, interpersonal behaviors, and aggression using repeated, situation-based measurement. We examine narcissism's relations with aggression across three levels of its theorized hierarchy (level 1: narcissism; level 2: grandiose vs. vulnerable narcissism; level 3: antagonism, agentic extraversion, and narcissistic neuroticism).

METHODS

Using an experience-sampling approach, the current study examined the effects of narcissism and its finer-grained components on daily affective experiences and aggressive behaviors in the context of interpersonal interactions. Data were collected from 477 undergraduate students who were instructed to complete four prompts a day for ten consecutive days.

RESULTS

Narcissism at the global construct level positively predicted multiple indices of episodic aggression (i.e., aggressive temper, aggressive urge, verbal aggression). At the dual-dimension level, grandiose narcissism specifically predicted aggression, and then at the trifurcated level, interpersonal antagonism predicted aggression by itself and in interaction with event-level negative affect. Negative affect consistently exhibited both within- and between-person effects on aggression.

CONCLUSION

In real-life social interactions, narcissism dimensions differentially affect the way individuals experience social interactions and process negative affect, and thus in both research and clinical practice, narcissism is best assessed as a heterogeneous, multidimensional construct.

Acting impulsively when "upset": Examining associations among negative urgency, undifferentiated negative affect, and impulsivity using momentary and experimental methods

INTRODUCTION

Negative urgency is a personality pathway toward impulsive behavior that increases risk for transdiagnostic psychopathology. Limited research supports the core tenant of urgency theory, that is, that individuals with high trait negative urgency act more impulsive when experiencing increased negative emotion. We hypothesized that it may not be negative emotion intensity, but difficulty in differentiating among negative emotions, that prompts impulsive behavior among individuals with elevated negative urgency.

METHODS

We tested this hypothesis in 200 undergraduates using both ecological momentary assessment (measured momentary undifferentiated negative affect and impulsivity) and experimental methods (manipulated emotion differentiation and measured behavioral impulsivity).

RESULTS

Momentary undifferentiated negative affect predicted impulsivity in the specific domains of work/school and exercise, but interactions between momentary undifferentiated negative affect and negative urgency were not supported. Manipulated emotion differentiation did not impact behavioral impulsivity regardless of negative urgency scores.

CONCLUSION

Inconsistent with theory, the impulsive behavior of individuals with negative urgency may not be conditional on elevated or undifferentiated negative affect.

Developmental trajectories of internalizing distress among ethnic minoritized mothers following childbirth: Associations with early child psychological adjustment

A substantial body of work has established that mothers' internalizing distress can negatively affect children's socioemotional development. Yet few studies have examined how distinct patterns of mothers' distress over time differentially impact child behaviors across early childhood. To address this gap, the current study explored developmental trajectories of mothers' internalizing distress and examined the associations of these patterns with child adjustment outcomes. Mexican immigrant, Dominican immigrant, and African American mothers (N = 272) were annually assessed for internalizing distress over the first 6 years following childbirth. Children's psychological adjustment (internalizing, externalizing, and hyperactivity behaviors) was measured at the last yearly assessment in first grade. A growth mixture model revealed two distinct classes of distress where mothers were classified as having low stable distress (82.4%) or moderate distress that began as stable then declined when their children were 64 months old (17.6%). Children of mothers in the moderate, late decline class showed greater internalizing, externalizing, and hyperactivity behaviors in the first grade compared to children of mothers in the low stable class. Findings highlight the necessity of supporting the mental health of ethnic minoritized mothers following childbirth and further expand our knowledge of family psychopathology to promote healthy psychological adjustment in children.

Religious Coping Is Differentially Associated with Physiological and Subjective Distress Indicators: Comparing Cortisol and Self-Report Patterns

Use of religious coping in response to life stress is associated with improved mental and physical health outcomes. The aim of this study was to examine the influence of religious coping on conscious self-reported and non-conscious physiological stress responses to an acute, real-world stressor to better understand how this benefit may be conferred. This study examined the trajectory of subjective distress and cortisol patterns leading up to and following a stressful college exam using daily diary and ambulatory saliva samples, respectively (N students = 246). Religious coping was not significantly associated with subjective reports of distress. However, prior to the exam, greater use of religious coping was associated with an ostensibly more adaptive accelerated return to a cortisol baseline. This protective effect was no longer significant when the exam was over, suggesting that religious coping acts as a protective buffer against physiological stress responses rather than aiding in subjective recovery from stress.

Perceived social support attenuates increased hostile reactions to traumatic threat

OBJECTIVE

Extant literature has seldom examined the naturalistic role of reaction to threat on downstream emotional distress while also considering buffers, such as perceived social support, to acute negative mental health outcomes. The present study examined how trauma symptoms, in reaction to a global stressor, predicted increased psychological distress via elevated emotional hostility and whether perceived social support modified such effects. We predicted a priori that increased exposure to trauma would be associated with increased hostility and global psychological distress, but that this path would be attenuated by greater levels of perceived social support, as individuals who report greater support exhibit greater emotional coping.

METHODS

We recruited 408 adults from a large university in the Midwestern United States to participate in a survey assessing past-week trauma, hostility, distress, and perceived social support following the initial COVID-19 lockdown. The survey was conducted in March 2020, directly after strict shelter-in-place orders were locally mandated. To test our hypotheses, we employed a moderated mediation analysis approach.

RESULTS

Results demonstrate that higher trauma predicted increased hostility, which in turn predicted increased distress, and trauma predicted distress via hostility (an indirect effect). As hypothesized, higher perceived social support attenuated the association between trauma and hostility.

CONCLUSION

Results support a hostile emotional pathway that may increase distress in the context of increased traumatic impact; however, social support likely buffers these effects, particularly in the face of new or novel threats and stressors. Findings suggest broad application for understanding the relation between the introduction of stressors, psychological distress, and social support.

Do Unified Protocol modules exert general or unique effects on anxiety, depression, and transdiagnostic targets?

Several transdiagnostic cognitive-behavior therapies include multiple treatment components. However, it is unclear whether some components are more efficacious than others at reducing symptoms or whether these components uniquely influence their putative mechanism of change. Participants (N = 70; Mage = 33.7; 67.1% female, 74.3% White) with a primary anxiety or depressive disorder were randomized to one of three standard or personalized sequences of core Unified Protocol modules. Using hierarchical linear modeling, we tested (a) whether the average session-to-session change in anxiety and depression differed between modules and (b) whether the average session-to-session change in the putative mechanism of each module differed between modules. All modules led to similar changes in anxiety, but Confronting Physical Sensations led to significantly less change in depression than other modules. There were no significant differences among modules predicting putative mechanisms of change, although there was a trend for Mindful Emotion Awareness to predict greater improvements in mindfulness than Understanding Emotions. Consistent with its transdiagnostic nature, UP modules may exert similar effects on anxiety and putative mechanisms of change, although interoceptive exposures may be less impactful for changing depressive symptoms and the mindfulness module may promote relatively specific improvements in mindfulness.

Negative affect provides a context for increased distrust in the daily lives of individuals with a history of childhood maltreatment

Evidence on individuals affected by posttraumatic stress disorder (PTSD) following childhood maltreatment (CM) supports cognitive models suggesting that trauma engenders distrust and interpersonal threat sensitivity. We examined the associations between CM and both distrust and interpersonal threat sensitivity in daily life and investigated whether momentary negative affect (NA) provides a context that strengthens this association. Hypotheses were based on cognitive models of trauma and the feelings-as-information theory. In a 7-day ambulatory assessment study with six semirandom daily prompts (2,295 total), we measured self-reported momentary NA and assessed behavioral trust as well as interpersonal threat sensitivity via facial emotion ratings with two novel experimental paradigms in 61 participants with varying levels of CM (45,900 total trials). As hypothesized, NA was associated with increased momentary distrust, β = .03, p = .002, and interpersonal threat sensitivity, β = -.01, p = .021. Higher levels of CM were associated with more negative emotion ratings, independent of affective context, β = -.07, p = .003. Momentary behavioral distrust was associated with CM at high levels of momentary NA, β = .02, p = .027. The findings for both tasks support the feelings-as-information theory and suggest that cognitive alterations surrounding distrust and interpersonal threat, which were originally proposed for PTSD, likely also affect individuals with a history of CM.

Emotion differentiation and intimate partner violence: Effects of provocation and alcohol intoxication

OBJECTIVE

This study investigated the impact of relational provocation on intimate partner violence (IPV) perpetration as a function of alcohol intoxication and individuals' emotion differentiation (ED; i.e., the ability to differentiate between positive and negative emotions). We hypothesized that provocation and acute intoxication would be associated with lower ED, such that individuals would demonstrate lower ED following provocation and while intoxicated. We also hypothesized an intoxication-by-ED interaction, such that only individuals who were intoxicated and undifferentiated would perpetrate IPV.

METHOD

Two hundred fifty community-based adults completed an aggression paradigm ostensibly with their romantic partners where they were randomly assigned to an alcohol or no-alcohol condition. Participants' ED across positive and negative subscales was calculated at baseline (Time 1), postprovocation and intoxication (Time 2), and postbehavioral aggression (Time 3). IPV was operationalized as the strength and duration of shocks issued to their partner during the aggression paradigm.

RESULTS

Both sober and intoxicated participants experienced lower ED following provocation, suggesting a main effect of provocation but no main effect of intoxication. There was a significant alcohol-by-ED interaction in the predicted direction. For intoxicated participants, low ED was associated with greater IPV perpetration. For sober participants, low ED was associated with less IPV perpetration.

CONCLUSIONS

Consistent with hypotheses, low ED is associated with greater IPV perpetration among intoxicated individuals. In contrast to prior research, low ED was associated with less IPV perpetration among sober individuals. Alcohol-related cognitive impairments may increase the likelihood of IPV perpetration by disrupting the ED process that may otherwise inhibit impulsive aggression.

Introduction and behavioral validation of the climate change distress and impairment scale

Governmental agencies and the medical and psychological professions are calling for a greater focus on the negative mental health effects of climate change (CC). As a first step, the field needs measures to distinguish affective/emotional distress due to CC from impairment that requires further scientific and diagnostic attention and that may require treatment in the future. To this end, we constructed the climate change distress and impairment scale, which distinguishes CC distress (spanning anger, anxiety, and sadness) from impairment. In four studies (N = 1699), we developed and validated English and German versions of the scale. Across samples, spanning 2021-2022, CC distress was at least moderate, while we observed general moderate to high levels of distress and low to moderate levels of impairment. In three English-speaking samples, younger individuals and women were most affected by CC distress, whereas this was not the case in a German-speaking sample, suggesting sociopolitical influencing factors. We demonstrate convergent validity with previous measures and discriminant validity for general negative affectivity and depressive and generalized anxiety disorder symptoms, which underlines that CC distress is not in itself pathological. Employing a fully incentivized social dilemma paradigm, we demonstrate that CC distress and (to a lesser degree) CC impairment predict pro-environmental behavior, underscoring them as possible drivers, and targets, of climate-change mitigation efforts.

Temporal dynamics of emotional processing: Parsing trial-wise variance of the late positive potential using Generalizability Theory

The reliability of individual trial event-related potential (ERP) components extracted from electroencephalogram has been consistently questioned since ERP research began. This ambivalence is based on misunderstood assumptions stemming from Cronbach and Classical Test Theory. Contemporary methods allow for the reliability of individual ERP trials to be estimated and for analyses of these trial-level ERP components to be meaningfully parsed. We illustrate the use of Generalizability Theory procedures in estimating the reliability of trial-level ERPs using the late positive potential (LPP), a neural measure of motivated attention toward emotionally evocative stimuli. Individuals (N = 88) completed a passive viewing task while continuous EEG was recorded. Variability in trial-level LPP responses was decomposed into facets corresponding to individual differences, chronological trial within block, stimulus type, their two-way interactions, and specific stimuli. We estimated various reliability coefficients and found that both overall and category-specific person-level LPP estimates have good-to-excellent reliability, while the reliability of within-person differences (i.e., change) between arousal categories was fair for the early LPP. These results were generally consistent across time windows, but were highest early in the LPP time course. We argue that investigating reliability using trial-level data allows researchers to pursue hypotheses focused on neurophysiological dynamics that unfold over the course of an experiment and not risk false inferences (i.e., ecological fallacy) when using person-level aggregates to deduce such processes. Moreover, such analyses provide information that allows researchers to optimize their protocols by potentially reducing the number of individual trials, burden on participants, and cost, while retaining sufficient reliability.

Statistical power for longitudinal developmental trajectories: The (non-)impact of age matching within measurement occasions

Recruiting participants for studies of early-life longitudinal development is challenging, often resulting in practical upper bounds in sample size and missing data due to attrition. These factors pose risks for the statistical power of such studies depending on the intended analytic model. One mitigation strategy is to increase measurement precision by conducting assessments of children as close to a fixed chronological age as possible. We present analyses that illustrate how such practices are only sometimes useful, focusing on cases where temporal trajectories are analyzed using multilevel modeling approaches. Simulations were conducted using results from two studies of longitudinal development. Data were generated according to both continuous and discrete developmental processes and factorially analyzed treating time on either interval, ordinal, or categorical scales. The power to detect continuously generated developmental processes was robust to, and even benefited from, increased variability around target ages. For discrete processes, power was unaffected when modeled ordinally/categorically, but declined steadily if modeled using exact chronological age on an interval scale. Our results suggest that in many circumstances, researchers may be unnecessarily devoting resources toward minimizing age sampling variability when studying functional patterns across time. In fact, when the theoretical developmental process is continuous, increasing the age sampling variability of assessments and utilizing multilevel models in favor of latent growth curve alternatives can be associated with substantial gains rather than reductions in power. Such considerations also extend to limited equivalent formulations of other common developmental models, such as panel analysis. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

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.

Preliminary evidence for the factor structure, concurrent validity, and construct validity of the Roommate Relationship Scale in a college sample

Roommate relationships are fundamental to the social environment of many emerging adults. However, no validated, widely used, measure of roommate relationship quality exists for examining the impact of these relationships on individual functioning and health. In this report, we present preliminary evidence of the factor structure, concurrent validity, and construct validity of the Roommate Relationship Scale (RRS) as a measure of roommate relationship quality using a sample of U.S. college students who participated in a multi-wave study. An exploratory factor analysis at the first wave, and confirmatory factor analyses (CFAs) with independent samples of new participants at each of two subsequent waves showed stable factor loadings and adequate fit. Moreover, the scale demonstrated good fit and reliability in a longitudinal multilevel CFA framework. The RRS significantly positively correlated with relationship length, self-esteem, extraversion, agreeableness, and conscientiousness, and negatively correlated with symptoms of anxiety and avoidant attachment style, indicating concurrent validity of the scale with respect to these constructs. Consistent with findings from other relationship types, self-reported RRS scores decrease longitudinally, both across and between semesters of academic life, indicating construct validity of the scale. We conclude that the RRS is useful for evaluating roommate relationship quality among U.S. college students, and hopefully beyond. Further research should validate the scale's utility in other, more diverse, populations and refine its underlying generating psychological process.

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 roles of negative emotion intensity, negative emotion differentiation, and self-compassion in loss of control eating

OBJECTIVE

Negative affect intensity is robustly related to binge eating, but the relationship between negative emotion differentiation (i.e., the ability to differentiate negatively-valenced emotions) and binge eating is unclear. Further, little is known about factors that might reduce emotion intensity and/or enhance emotion differentiation, thereby reducing binge eating. Self-compassion is consistently linked to less binge eating, which may be due to decreased negative affect and/or an enhanced ability to differentiate emotions. The current study examined the roles of negative emotion intensity, negative emotion differentiation, and self-compassion in binge eating using ecological momentary assessment.

METHOD

Participants were 201 university students (52.2% female) who completed questionnaires assessing affect seven times a day, and engagement in loss of control (LOC) eating episodes at the end of each day, for 10 days. The average of sadness, fear, guilt, and hostility subscales represented negative emotion intensity; intraclass correlations across negative affect subscales defined negative emotion differentiation. Both daily (i.e., within-person) and trait (i.e., between-person) emotion variables were examined as predictors.

RESULTS

Between-person negative emotion intensity, but not negative emotion differentiation, significantly predicted LOC eating occurrence. Self-compassion had a significant effect on LOC eating frequency, and this relationship was partially mediated via negative emotion intensity, but not via negative emotion differentiation.

DISCUSSION

Lower levels of negative emotion intensity partially account for the relationship between greater self-compassion and less frequent LOC eating. These findings highlight the importance of cultivating self-compassion to down-regulate negative emotions and to reduce LOC eating.

PUBLIC SIGNIFICANCE STATEMENT

Our findings suggest that university students who approach their limitations compassionately experience fewer negative emotions in daily life and engage in less loss of control eating. Lower levels of negative affect partially explain this relationship between self-compassion and loss of control eating. These results highlight the importance of cultivating an understanding and a compassionate attitude toward oneself for reducing eating pathology.

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.

Development and Validation of a Smartphone-Based App for the Longitudinal Assessment of Anxiety in Daily Life

Current methods to assess human anxiety often ignore that anxiety is a dynamic process and have limitations such as high recall bias and low generalizability to real life. Smartphone apps using ecological momentary assessment (EMA) may overcome such limitations. We developed a smartphone app for the longitudinal evaluation of anxiety symptoms using EMA. We assessed the feasibility (retention and compliance) and psychometric properties (reliability and validity) of the app over 6 months in a sample of 99 participants with different levels of anxiety. The EMA-based smartphone app was highly feasible. It showed excellent within-person and between-person reliability, high convergent and moderate discriminant validity, and significant incremental validity. Assessing anxiety longitudinally using a smartphone and following EMA principles is feasible and can be reliable and valid. Studies combining EMA-based anxiety longitudinal assessments with other assessment methods deserve further research and may offer novel insights into human anxiety.

Ratings of dimensional traits in clinical practice: Comparing therapist and client perspectives

Research has repeatedly evidenced the structural validity of the five-factor model (FFM), but questions remain about the use of its dimensions in clinical practice. Samuel and colleagues (2018) found therapists reported their clients had lower levels of personality pathology compared with clients' own self-reports when using the unipolar Personality Inventory for the DSM-5 (PID-5) scale. The present study utilized the same sample of 54 client-therapist dyads to examine their use of the bipolar FFM Rating Form. When comparing the clinical ratings to expertly rated healthy profile ratings, clients rated themselves as more aligned with healthy than their therapists rated them. Alternatively, clients were up to 3.6 times more likely to use the extreme (i.e., theoretically pathological) ratings of the FFM Rating Form compared with their therapists. These results suggest that therapists and clients use these measures quite differently, and we cannot firmly conclude which source reports more pathology. Theoretical explanations, limitations, and future directions are discussed. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

The effect of momentary mood on appraisal of facial affect and distrust: an experimental approach using ambulatory assessment

Previous laboratory studies have demonstrated that an observer's current mood can influence their processing of facial stimuli, for instance, the appraisal of facial affect. The aim of the present study was to explore the association between current mood and face processing in participants' daily lives, thereby making use of naturally occurring affective states. We employed Ambulatory Assessment (AA) and included two experimental tasks to test whether current mood predicts how participants evaluate (i) the valence of emotional faces and (ii) facial trustworthiness. We hypothesised a mood-congruent processing, such that individuals would rate pictures of faces more negatively and less trustworthy, the more negative their current mood was. We recruited 42 participants who completed a 7-day AA study with six random prompts per day. At each prompt, participants provided self-reports on momentary mood and completed an emotion rating task and a hypothetical distrust game. Results show that negative momentary mood was significantly associated with higher levels of distrust, but was not significantly associated with more negative emotion ratings. We discuss the incremental value and feasibility of implementing experimental tasks in AA contexts and the opportunities this opens for assessing affective and cognitive processes in natural environments.

The Impact of Personality and Lifestyle Change on Distress During the COVID-19 Pandemic

The COVID-19 pandemic provided a unique opportunity for quantifying the impact of Five Factor Model personality domains (i.e. neuroticism, extraversion, openness, agreeableness, and conscientiousness) and COVID-related lifestyle changes on psychological distress. To examine these relationships, we designed and preregistered the present study (https://osf.io/qfw9h). We assessed a large, heterogeneous sample including undergraduates, graduate students, faculty, and staff of a large, public, Midwestern university (n = 1055) to ascertain whether personality domains uniquely predicted distress in response to COVID-19 shelter-in-place orders. This was a three-panel study in which the same potential participant pools were invited to participate at each survey announcement. Data collection occurred between early March through late May 2020, from within days of local shelter-in-place order onset to within days of reaching 100,000 COVID-related deaths in the USA. Domain and distress scores were determined from self-reported ratings on the Big Five Inventory and the 21-Item Depression Anxiety and Stress Scales, respectively. Participants also reported personal experiences with six COVID-specific lifestyle impacts: insufficient outdoor or indoor living space, job insecurity, income insecurity, or taking care of or homeschooling school-aged children during working hours. Zero-order correlations revealed that all personality domains except openness had statistically significant correlations with distress, and all correlations were negative except for that of neuroticism. When entered simultaneously, neuroticism was the predominant risk factor of distress that held across all preregistered and exploratory analyses. Our expectation that extraversion would be negatively associated with distress was not supported broadly, while agreeableness was a unique potential risk factor (though this effect was mostly limited to exploratory analyses). The results especially highlight the link between employment and income uncertainty with psychological distress, while also identifying insufficient indoor and outdoor space as potential risk factors. We hope these findings inform future public health action and further emphasize the utility of personality trait models in general.

The "Big Everything": Integrating and investigating dimensional models of psychopathology, personality, personality pathology, and cognitive functioning

Common factors are increasingly used to model the structure of psychopathology ("p"), personality (General Factor of Personality [GFP]), pathological personality (General Factor of Pathological Personality [GFPP]), and intelligence ("g"). Using 4 waves spanning ages 18-29 in a cohort of college students (baseline n = 489), this study used indicators of psychopathology, personality, pathological personality, and cognitive functioning to compare models that included Cognitive Functioning, p, GFP, GFPP, and a "Big Everything" factor (which included cross-domain measures as indicators). GFP, GFPP, and p exhibited substantial overlap, and the Big Everything factor accounted for considerable variance in psychopathology, personality, and pathological personality indicators. Only a self-report measure of cognitive functioning loaded significantly onto the Big Everything. This study highlights concerns in the pursuit of identifying and reifying common factors based on the modeling of residual variances and limitations of using factor modeling to determine the structure of psychologically relevant phenomena.

Reliability of Differential Item Functioning in Alcohol Use Disorder: Bayesian Meta-Analysis of Criteria Discrimination Estimates

Numerous studies leverage item response theory (IRT) methods to examine measurement characteristics of alcohol use disorder (AUD) diagnostic criteria. Less work has examined the consistency of AUD IRT parameter estimates, an essential step for establishing measurement invariance, making statements about symptom diagnosticity, and validating the theoretical construct. A Bayesian meta-analysis of IRT discrimination values for AUD criteria across 33 independent samples (Total N = 321,998) revealed that overall consistency of AUD criteria discriminations was low (generalized intraclass correlation range = .105-.249). However, specific study characteristics accounted for substantial variability, suggesting that the unreliability is partially systematic. We replicated evidence of differential item functioning (DIF) via established factors (e.g., age, gender), but the magnitudes were small compared with DIF associated with assessment instrument. These results offer practical recommendations regarding which instruments to use when specific AUD criteria are of interest and which criteria are most sensitive when comparing demographic groups.

High-resolution metabolic mapping of the cerebellum using 2D zoom magnetic resonance spectroscopic imaging

PURPOSE

The human cerebellum plays an important role in the functional activity of the cerebrum, ranging from motor to cognitive systems given its relaying role between the spinal cord and cerebrum. The cerebellum poses many challenges to Magnetic Resonance Spectroscopic Imaging (MRSI) due to its caudal location, susceptibility to physiological artifacts, and partial volume artifacts resulting from its complex anatomical structure. Thus, in the present study, we propose a high-resolution MRSI acquisition scheme for the cerebellum.

METHODS

A zoom or reduced field of view (rFOV) metabolite-cycled MRSI acquisition at 3 Tesla, with a grid of 48 × 48, was developed to achieve a nominal resolution of 62.5 μL. Single-slice rFOV MRSI data were acquired from the cerebellum of 5 healthy subjects with a nominal resolution of 2.5 × 2.5 × 10 mm³ in 9.6 min. Spectra were quantified using the LCModel package. A spatially unbiased atlas template of the cerebellum was used to analyze metabolite distributions in the cerebellum.

RESULTS

The superior quality of the achieved spectra-enabled generation of high-resolution metabolic maps of total N-acetylaspartate, total Creatine (tCr), total Choline (tCho), glutamate+glutamine, and myo-inositol, with Cramér-Rao lower bounds below 50%. A template-based regions of interest (ROI) analysis resulted in spatially dependent metabolite distributions in 9 ROIs. The group-averaged high-resolution metabolite maps across subjects increased the contrast-to-noise ratio between cerebellum regions.

CONCLUSION

These findings indicate that very high-resolution metabolite probing of the cerebellum is feasible using rFOV or zoomed MRSI at 3 Tesla.

A User-centered Decision-aiding Process for Selecting Power Analysis Tools

A priori power analyses have become increasingly popular in scientific communities, but the practice has not been widely discussed by HFE researchers. Given the complexity of conducting such analyses, software tools are essential. We review the emergence and current state of power analysis software tools, and use the concept of User-Centered Design as an analytical lens for examining the relationship between researchers' needs and power analysis tools' characteristics. Centering on users' wants and needs, we propose a decision-aiding process to assist researchers in identifying appropriate power analysis tools. This process consists of five user-centered considerations - two functional criteria (software input; software output) and three usability heuristics (learnability; ease of use; accessibility) - which are organized into a workflow. These criteria and heuristics are translated into questions that researchers should go through during the decision process. We illustrate use of the decision-aiding process with three example scenarios and lay out implications for researchers.

Using generalizability theory to evaluate the comparative reliability of developmental measures in neurogenetic syndrome and low-risk populations

BACKGROUND

The lack of available measures that can reliably characterize early developmental skills in children with neurogenetic syndromes (NGS) poses a significant challenge for research on early development in these populations. Although syndrome-specific measures may sometimes be necessary, a more cost- and time-efficient solution would be to identify existing measures that are appropriate for use in special populations or optimize existing measures to be used in these groups. Reliability is an important metric of psychometric rigor to consider when auditing and optimizing assessment tools for NGS. In this study, we use Generalizability Theory, an extension of classical test theory, as a novel approach for more comprehensively characterizing the reliability of existing measures and making decisions about their use in the field of NGS research.

METHODS

We conducted generalizability analyses on a popular early social communication screener, the Communication and Symbolic Behavior Scales-Infant-Toddler Checklist (CSBS-ITC), collected on 172 children (41 Angelman syndrome, 30 Prader-Willi syndrome, 42 Williams syndrome, 59 low-risk controls).

RESULTS

Overall, the CSBS-ITC demonstrated at least adequate reliability in the NGS groups included in this study, particularly for the Prader-Willi and Williams syndrome groups. However, the sources of systematic error variance in the CSBS-ITC varied greatly between the low-risk control and NGS groups. Moreover, as unassessed in previous research, the CSBS-ITC demonstrated substantial differences in variance sources among the NGS groups. Reliability of CSBS-ITC scores was highest when averaging across all measurement points for a given child and was generally similar or better in the NGS groups compared to the low-risk control group.

CONCLUSIONS

Our findings suggest that the CSBS-ITC communicates different information about the reliability of stability versus change, in low-risk control and NGS samples, respectively, and that psychometric approaches like Generalizability Theory can provide more complete information about the reliability of existing measures and inform decisions about how measures are used in research on early development in NGS.

Drinking motives moderate daily-life associations between affect and alcohol use in individuals with borderline personality disorder

People often report drinking to cope with negative affect (NA) or to enhance positive affect (PA). However, findings from daily life studies examining the interaction of motives and affect to predict alcohol use are mixed. Individuals with borderline personality disorder (BPD) may be particularly susceptible to drinking for the purpose of changing affective states, representing a population in which these patterns may be more readily identifiable in daily life. We tested whether drinking motives moderate daily life associations between affect and drinking in individuals with BPD. Regular drinkers with BPD (N = 54; 81.5% female) completed ecological momentary assessments approximately 6-10 times daily for 21 days. We tested whether the interactions between (a) person-level coping motives and NA so far that day (i.e., cumulative-average NA), and (b) person-level enhancement and cumulative-average PA were associated with subsequent drinking. We also tested whether effects differed for the initiation versus continuation of a drinking episode. Using generalized estimating equations, the interaction between coping and cumulative-average NA was positively associated with momentary drinking, with some evidence for a stronger relation during the continuation of drinking. The interaction between enhancement motives and cumulative-average PA was positively associated with initiation but negatively associated with continuation of drinking. Our novel approach of using cumulative-average affect and distinguishing initiation and continuation of drinking allowed us to examine differential momentary patterns across the drinking episode, and results suggest that awareness of motives as well as affect leading up to and during drinking may be a useful intervention target.

Perceptions of Collaborations: How Many Cooks Seem to Spoil the Broth?

Workers often work in groups of varying sizes, and those workers’ work is often judged by others. To examine how the two might relate, we first asked respondents to report the optimal number of collaborators for a variety of different tasks, finding substantial variability across tasks (Supplementary Study) that tracked with perceived task complexity (Study 1). Accordingly, framing a given task as more complex made people want more collaborators collaborating on it (Study 2), and believing that a task had been performed by the right number of collaborators—neither too few nor too many—fostered more favorable evaluations of both simulated (Study 3) and real (Study 4) experience with the collaborative output. The results of this collaboration suggest that perceivers hold an optimal size in mind when thinking about collaborations and that collaborative work benefits from ostensibly hitting this mark.

Concurrent and lagged associations of prescription opioid use with pain and negative affect in the daily lives of chronic pain patients

OBJECTIVE

Prescribed opioids for chronic pain management contribute significantly to the opioid crisis. There is a need to understand the real-world benefits that, despite risks, lead chronic pain patients to persist in opioid use. Negative reinforcement models of addiction posit that individuals use substances to reduce aversive states but have seldom been applied to prescribed opioids. Using ecological momentary assessment, we examined reciprocal associations between opioid use and physical pain, for which opioids are prescribed, and negative affect (NA), for which they are not.

METHOD

Chronic low back pain patients on long-term opioid therapy (n = 34) without significant past-year opioid misuse reported multiple times daily via smartphone over 2 weeks (nobservations = 2,285). We hypothesized that pain and NA would be positively associated with subsequent opioid use, and that use would be negatively associated with subsequent pain and NA.

RESULTS

Time-lagged multilevel models indicated that participants were more likely to use opioids and in larger doses following elevated pain and NA. There was also an interaction of concurrent pain and NA on opioid dose. In turn, participants reported reduced pain and NA following larger doses. Additionally, individuals at high risk for opioid misuse, compared with low risk, took larger doses following pain, but also experienced smaller subsequent pain and NA reductions.

CONCLUSIONS

Opioid use was bidirectionally associated with pain and NA. Findings fit negative reinforcement models associated with risk of developing opioid use disorder. Educating patients and providers about negative reinforcement may help reduce opioid use and opioid-associated risks. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Block-wise and trial-wise analyses of the late positive potential reveal distinct affective trajectories as a function of neuroticism

The late positive potential (LPP), an event-related potential that is modulated by affective stimuli, is often employed as an objective measure of momentary emotional reactivity in affective neuroscience research. A wide range of tasks are used to elicit the LPP, yet relatively few studies assess how task-specific methodological differences influence observed effects on LPP amplitude. The present study tested whether the LPP systematically varies across repeated blocks of affective stimuli in terms of block-wise averages and trial-wise slopes, as well as if this variability relates to trait affective style. Participants (N = 112) completed a passive-viewing task designed to assess carry-over effects from one fixed valence block to the next. Rather than single scores for each image type averaged across all trials, as is typically done, the LPP was investigated first as averages across single blocks organized by valence and arousal categories and then trial-wise within these blocks. Traditional analyses and multilevel modeling procedures were employed to investigate effects. Results revealed that average LPP amplitude increased for the second versus the first blocks for affective but not neutral images. Moreover, trial-wise variation in the LPP systematically related to trait affective style: neuroticism moderated slopes of reactivity to pleasant and unpleasant images and produced affective carry-over effects for those higher in neuroticism. Together, results suggest that LPP amplitude is systematically modulated by block sequence, which could explain discrepancies across studies. Furthermore, block-wise averages capture only a portion of reactivity, obscuring trial-wise dynamics that are more closely aligned with theoretical frameworks of emotion.

The influence of sample selection on the structure of psychopathology symptom networks: An example with alcohol use disorder

Increasingly, the structure of mental disorders has been studied in the form of a network, characterizing how symptoms or criteria interact with and influence each other. Many studies of psychiatric symptoms and diagnostic criteria employ community or population-based surveys using co-occurrence of the symptoms/criteria to form the networks. However, given the overall low prevalence rates of mental disorders and their symptoms in the general population, most of those surveyed may not exhibit or endorse any symptoms and yet are often included in network analyses. Consequently, because network models are built on associations between symptoms/criteria, much of the observed variability is driven by individuals who are asymptomatic. Using data from the National Epidemiological Survey of Alcohol and Related Conditions (NESARC) Wave 2 and NESARC-III, we explore the effect of these "asymptomatic" observations on the estimated relations among diagnostic criteria of alcohol use disorder to determine the effects of such observations on estimated networks. We do so using the eLasso tool, as well as with traditional measures of correlation between binary variables (the Φ coefficient and odds ratio). We find that when the proportion of asymptomatic individuals are systematically culled from the sample, the estimated pairwise relations are often significantly affected, even changing signs in some cases. Our findings indicate that researchers should carefully consider the population(s) included in their sample and the implications it has on their interpretations of pairwise similarity estimates and resulting generalizability and reproducibility of estimates of network structures.

Conducting sensitivity analyses to identify and buffer power vulnerabilities in studies examining substance use over time

INTRODUCTION

A priori power analysis is increasingly being recognized as a useful tool for designing efficient research studies that improve the probability of robust and publishable results. However, power analyses for many empirical designs in the addiction sciences require consideration of numerous parameters. Identifying appropriate parameter estimates is challenging due to multiple sources of uncertainty, which can limit power analyses' utility.

METHOD

We demonstrate a sensitivity analysis approach for systematically investigating the impact of various model parameters on power. We illustrate this approach using three design aspects of importance for substance use researchers conducting longitudinal studies base rates, individual differences (i.e., random slopes), and correlated predictors (e.g., co-use) and examine how sensitivity analyses can illuminate strategies for controlling power vulnerabilities in such parameters.

RESULTS

Even large numbers of participants and/or repeated assessments can be insufficient to observe associations when substance use base rates are too low or too high. Large individual differences can adversely affect power, even with increased assessments. Collinear predictors are rarely detrimental unless the correlation is high.

CONCLUSIONS

Increasing participants is usually more effective at buffering power than increasing assessments. Research designs can often enhance power by assessing participants twice as frequently as substance use occurs. Heterogeneity should be carefully estimated or empirically controlled, whereas collinearity infrequently impacts power significantly. Sensitivity analyses can identify regions of model parameter spaces that are vulnerable to bad guesses or sampling variability. These insights can be used to design robust studies that make optimal use of limited resources.

What predicts who we approach for social support? Tests of the attachment figure and strong ties hypotheses

Before people seek support for an issue, they must choose whom in their support network to approach. Two prominent supporter-selection hypotheses are the attachment figure hypothesis and the strong ties hypothesis, housed in psychology and sociology, respectively. People are expected to have a special preference for attachment figures and also for strong ties and to seek them more frequently than others. Despite the widespread acceptance of these hypotheses, neither has ever been tested, we argue, with the most appropriate methods for their claims. Moreover, no one has ever tested whether the 2 theories might not be independent, that is, whether one might subsume the other. To properly test the theories, one requires intranetwork, enacted support-seeking data, and the theories must be modeled not just separately but also simultaneously. The present article reports 3 such studies. In Studies 1 and 3, a sample of adults reported their supporter-selection decisions for a single stressful event, and in Study 2, a sample of emerging adults reported their supporter-selection decisions for a period of 2 weeks. Evidence showed that each theory uniquely predicted supporter-selection decisions. For each theory the data revealed both expected and unexpected findings. Attachment figures were selectively sought for support, but this preference did not get stronger as issues became more severe. Stronger ties were selected more often than weaker ties; however, the strong tie effect emerged as 2 independent effects rather than one (closeness and interaction frequency). Taken together, the studies supported both theories, but also suggest the need for further theoretical development. (PsycINFO Database Record (c) 2020 APA, all rights reserved).

Not all alcohol use disorder criteria are equally severe: Toward severity grading of individual criteria in college drinkers

Alcohol use disorder (AUD) diagnosis in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatric Association, 2013) contains a severity gradient based on number of criteria endorsed, implicitly assuming criteria are interchangeable. However, criteria vary widely in endorsement rates, implying differences in the latent severity associated with a symptom (e.g., Lane, Steinley, & Sher, 2016) and demonstrating criteria are not interchangeable (Lane & Sher, 2015). We evaluated whether variation in the severity of criteria could be resolved by employing multiple indicators of each criterion varying in item-level severity. We assessed 909 undergraduate students aged 18 years or older with at least 12 drinking occasions in the past year. Participants self-administered questions on alcohol consumption and past year AUD symptoms via an online survey. For each of the 11 AUD criteria, we selected three indicators based on the difficulty values of the one-parameter logistic item response theory model ranging from low to high. We first tested a higher order AUD factor defined by 11 lower order criterion factors, χ2(551) = 2,959.35, p < .0001; root mean square error of approximation = 0.09. The 33 items were used to create severity scores: a criterion count (0-11), symptom count (0-33), and factor scores derived from a bifactor model. Though our new scores resulted in incremental validity over DSM-5 across a range of external validators, when the standardized regression estimates were compared, the new scores did not consistently outperform the DSM-5 suggesting this approach is viable for developing more sensitive diagnostic instruments but needs further refinement.

Dyadic interactions in children exhibiting the broader autism phenotype: Is the broader autism phenotype distinguishable from typical development?

In families raising a child with an autism spectrum disorder (ASD), infant siblings are at elevated risk for ASD and other developmental concerns, including elements of the broader autism phenotype (BAP). Typically, the BAP is indexed using standardized developmental assessments; however, these measures do not capture a number of social difficulties commonly associated with the BAP. The present study aims to expand our developmental understanding of the BAP by comparing children exhibiting the BAP to their typically developing peers on, (a) standardized measures of development, and (b) social behaviors exhibited during dyadic play interactions. As part of a prospective study, dyads were recruited from families with at least one older child with ASD (high-risk, n = 36), and families with no history of ASD (low-risk, n = 38). During laboratory visits at 12, 15, 18, and 24 months of age, infants completed a series of standardized assessments and a mother-child play interaction. Dyadic play interactions were micro-analytically coded for gaze, positive affect, and vocalizations to create theory-driven composites to index dyadic synchrony and responsiveness. Videos were also coded with an existing rating scheme for joint engagement and child responsiveness. Multilevel models revealed significant group differences on select constructs within the first 2 years. Language and cognitive differences emerged by 24 months of age, whereas dyadic differences were evident as early as 15 months. Recognizing the increasing demand for elevated-risk interventions, these findings highlight several social constructs through which interventions may identify risk and promote optimal development. Autism Res 2019, 12: 469-481 © 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: In families raising children with an autism spectrum disorder (ASD), younger siblings are at an increased risk for social and developmental difficulties that characterize a "broader autism phenotype." The present study explored the emergence of social, language, and cognitive differences in the first 2 years of life. Social differences were evident as early as 15 months of age for several play-based measures, and language and cognitive differences emerged by 24 months of age. For infant siblings of children with ASD, some of the earliest behavioral marks for subclinical features of ASD are evident within the first 2 years of life.

Interpersonal stressors and negative affect in individuals with borderline personality disorder and community adults in daily life: A replication and extension

Affective instability and interpersonal stress are key features of borderline personality disorder (BPD). They were shown to covary in the daily lives of patients in a recent ambulatory assessment study (Hepp et al., 2017) that observed comparatively larger positive associations between interpersonal stressors and negative affect in individuals with BPD than those with depressive disorders. The present study sought to replicate these findings, collecting data on hostility, sadness, fear, and rejection or disagreement events from 56 BPD and 60 community control participants for 21 days, 6 times a day. Using identical statistical procedures, the positive associations between momentary rejection/disagreement and hostility, sadness, and fear were replicated. Again replicating the original study, the rejection-hostility, rejection-sadness, and disagreement-hostility associations were significantly stronger in the BPD group. Time-lagged analyses extended the original study, revealing that rejection was associated with subsequent hostility and sadness more strongly in the BPD group, as was disagreement with subsequent hostility and fear. Though small, we argue that the observed group differences reflect meaningful pervasive responses in a daily life context. Future research should consider these when implementing affect regulation strategies that are applicable in interpersonal contexts for all individuals, but particularly those with BPD.

Momentary assessment of everyday physical pain in outpatients with borderline personality disorder

Borderline personality disorder (BPD) is a severe psychiatric disorder associated with dysregulation in multiple domains of functioning. Physical health, and specifically pain, is one such domain that has gone understudied. Although evidence suggests that BPD is associated with chronic pain, few studies have examined nonchronic pain in the disorder. The current study used ambulatory assessment to examine momentary physical pain in everyday life in BPD outpatients (N = 26) and community comparisons (COM; N = 26) not in treatment for chronic pain (N_observations = 5,458). We predicted and observed that BPD outpatients would report greater pain intensity and greater pain variability than COM comparisons. We also examined the relationship of pain and emotion dysregulation, a core feature of BPD, by testing the association between pain and negative affect concurrently and lagged over time. We predicted that momentary pain and negative affect would be associated in both groups, but that pain would predict negative affect more strongly in the BPD group. As predicted, concurrent pain and negative affect were associated in both groups, and groups differed significantly in terms of the association of lagged pain and next-assessment negative affect, with a negative association in the COM group. The current study represents a preliminary first step, finding that pain is relevant to the everyday experience of BPD individuals. This pain propensity may contribute to the elevated prevalence of BPD in chronic pain samples. Further, BPD individuals demonstrated emotional reactivity to pain, suggesting that pain may be a contributor to emotion dysregulation in this disorder.

Initial elevation bias in subjective reports

People's reports of their thoughts, feelings, and behaviors are used in many fields of biomedical and social science. When these states have been studied over time, researchers have often observed an unpredicted and puzzling decrease with repeated assessment. When noted, this pattern has been called an "attenuation effect," suggesting that the effect is due to bias in later reports. However, the pattern could also be consistent with an initial elevation bias. We present systematic, experimental investigations of this effect in four field studies (study 1: n = 870; study 2: n = 246; study 3: n = 870; study 4: n = 141). Findings show clear support for an initial elevation bias rather than a later decline. This bias is larger for reports of internal states than for behaviors and for negative mental states and physical symptoms than for positive states. We encourage increased awareness and investigation of this initial elevation bias in all research using subjective reports.

An Experimental Investigation of Drunk Personality Using Self and Observer Reports

Across various cultures there are robust stereotypes regarding how alcohol intoxication alters individuals' normative personalities. However, whether these stereotypes are rooted in genuine average effects or in salient, socially-proliferated exemplars remain unclear. The current study tested if differences between sober and intoxicated personality expression can be observed reliably by trained raters during a drinking episode. Participants (N = 156), half of whom received alcohol, attended laboratory sessions in same-gender friend groups and engaged in activities designed to elicit a range of personality expression. Participants completed self-reports of their "typical" sober and drunk personalities two weeks prior to their sessions and via two short measures during the session. Additionally, participants were recorded and rated by multiple (Range = 5-17) trained raters using three personality measures. Self-perceptions of sober-to-drunk personality differences were more pervasive than observer-perceptions, but alcohol-induced changes in Extraversion, specifically, were robust across measures and reporters.

Evidence that disrupted orienting to evaluative social feedback undermines error correction in rejection sensitive women

For individuals high in Rejection Sensitivity (RS), a learned orientation to anxiously expect rejection from valued others, negative feedback from social sources may disrupt engagement with learning opportunities, impeding recovery from mistakes. One context in which this disruption may be particularly pronounced is among women high in RS following evaluation by a male in authority. To investigate this prediction, 40 college students (50% female) answered general knowledge questions followed by immediate performance feedback and the correct answer while we recorded event-related potentials. Error correction was measured with a subsequent surprise retest. Performance feedback was either nonsocial (asterisk/tone) or social (male professor's face/voice). Attention and learning were indexed respectively by the anterior frontal P3a (attentional orienting) and a set of negative-going waveforms over left inferior-posterior regions associated with successful encoding. For women, but not men, higher RS scores predicted poorer error correction in the social condition. A path analysis suggested that, for women, high RS disrupted attentional orienting to the social-evaluative performance feedback, which affected subsequent memory for the correct answer by reducing engagement with learning opportunities. These results suggest a mechanism for how social feedback may impede learning among women who are high in RS.

Interpersonal problems and negative affect in Borderline Personality and Depressive Disorders in daily life

Theories of Borderline Personality Disorder (BPD) suggest that interpersonal problems in BPD act as triggers for negative affect and, at the same time, are a possible result of affective dysregulation. Therefore, we assessed the relations between momentary negative affect (hostility, sadness, fear) and interpersonal problems (rejection, disagreement) in a sample of 80 BPD and 51 depressed outpatients at 6 time-points over 28 days. Data were analyzed using multivariate multi-level modeling to separate momentary-, day-, and person-level effects. Results revealed a mutually reinforcing relationship between disagreement and hostility, rejection and hostility, and between rejection and sadness in both groups, at the momentary and day level. The mutual reinforcement between hostility and rejection/disagreement was significantly stronger in the BPD group. Moreover, the link between rejection and sadness was present at all three levels of analysis for the BPD group, while it was localized to the momentary level in the depressed group.

Cannabis and alcohol use, affect and impulsivity in psychiatric out-patients' daily lives

BACKGROUND AND AIMS

Cannabis and alcohol are the most commonly used (il)licit drugs world-wide. We compared the effects of cannabis and alcohol use on within-person changes in impulsivity, hostility and positive affect at the momentary and daily levels, as they occurred in daily life.

DESIGN

Observational study involving ecological momentary assessments collected via electronic diaries six random times a day for 28 consecutive days.

SETTING

Out-patients' everyday life contexts in Columbia, MO, USA.

PARTICIPANTS

Ninety-three adult psychiatric out-patients (85% female; mean = 30.9 years old) with borderline personality or depressive disorders, who reported using only cannabis (n = 3), only alcohol (n = 58) or both (n = 32) at least once during the study period.

MEASUREMENTS

Real-time, standard self-report measures of impulsivity, hostility and positive affect, as impacted by momentary reports of cannabis and alcohol use.

FINDINGS

Cannabis use was associated with elevated feelings of impulsivity at the day level [b = 0.83, 95% confidence interval (CI) = 0.17-1.49] and increased hostility at the momentary (b = 0.07, 95% CI = 0.01-0.12) and person (b = 0.81, 95% CI = 0.15-1.47) level. Alcohol use was associated with elevated feelings of impulsivity at the momentary (b = 0.42, 95% CI = 0.13-0.71) and day levels (b = 0.82, 95% CI = 0.22-1.41) and increased positive affect at the momentary (b = 0.12, 95% CI = 0.06-0.18) and day (b = 0.33, 95% CI = 0.16-0.49) levels.

CONCLUSIONS

Cannabis and alcohol use are associated with increases in impulsivity (both), hostility (cannabis) and positive affect (alcohol) in daily life, and these effects are part of separate processes that operate on different time-scales (i.e. momentary versus daily).

Assessment of Withdrawal and Hangover is Confounded in the Alcohol Use Disorder and Associated Disabilities Interview Schedule: Withdrawal Prevalence is Likely Inflated

BACKGROUND

The Alcohol Use Disorder and Associated Disabilities Interview Schedule-IV (AUDADIS-IV) and AUDADIS-5 are diagnostic interviews used in major epidemiological and other studies of alcohol use disorder (AUD). Much of what we know regarding the prevalence of AUD in the United States is based upon this interview. However, past research and meta-analytic evidence suggest that differential operationalization of the AUD criteria across instruments can lead to differential endorsement of symptoms and resulting AUD diagnosis rates. In particular, studies employing the AUDADIS are observed to have markedly higher endorsement rates of withdrawal than other large epidemiological studies. One explanation for this is that when assessing withdrawal, the AUDADIS combines effects from the morning after drinking with those from the days following, thereby conflating hangover and withdrawal.

METHODS

This study addresses whether this operationalization confounds rates of endorsement when compared to simpler, less ambiguous hangover or withdrawal stems. To this aim, 497 college student drinkers were randomized into 1 of 3 stem conditions: (i) hangover (n = 164), (ii) withdrawal (n = 167), or (iii) combined AUDADIS-IV (n = 166).

RESULTS

Across conditions, participants were more likely to report the occurrence of each withdrawal symptom in the combined stem condition than in the explicit withdrawal stem condition, but not in the explicit hangover stem condition. Within the combined stem condition, probed symptoms were more likely to be reported as a result of a hangover.

CONCLUSIONS

The AUDADIS potentially results in false positives for withdrawal, arguably a pathognomonic symptom of alcoholism and, in turn, likely affects rates of the diagnosis of AUD.

Alcohol Craving and Consumption in Borderline Personality Disorder: When, Where, and with Whom

Substance use is highly prevalent in our society, and substance use disorders are comorbid with most psychiatric disorders, including borderline personality disorder (BPD; Grant et al., 2006, 2008). Craving is a fundamental feature of addiction and disorder, yet the contexts in which craving occurs and is associated with substance use is still under-researched. We examined alcohol craving and consumption in a sample of 56 BPD individuals and a comparison group of community drinkers (COM; n = 60) who carried electronic diaries for approximately 21 days. BPD individuals reported more craving than COM individuals in most contexts. Compared to COM individuals, elevated craving in BPD individuals was paralleled by more drinking when at work, at home, and with romantic partners, coworkers, and children. These findings identify contexts of particular relevance to those with BPD and other mood/anxiety disorders in which craving may lead to risky and maladaptive alcohol use.

Momentary symptoms of borderline personality disorder as a product of trait personality and social context

Past studies identify Five Factor Model (FFM) domains that are characteristic of borderline personality disorder (BPD), including those associated with specific BPD symptoms, at a between-person level. The present study replicated these between-person associations and extended past research by assessing whether the FFM explains within-person variance in the manifestation of momentary BPD symptoms in the presence or absence of close social contact (CSC). We measured CSC and the BPD core symptoms negative affectivity, impulsivity, and interpersonal problems in 74 BPD patients and in a clinical control group of 40 depressed patients over the course of 28 days, 6 times a day. The FFM domains showed specificity in predicting momentary BPD symptoms and interacted with CSC in doing so. In particular, for BPD individuals only, momentary impulsivity and interpersonal problems were associated with higher neuroticism and extraversion and lower agreeableness, and these associations were especially strong in situations involving CSC. Negative affectivity was predicted by neuroticism for both groups of individuals, and this association was generally unaffected by CSC. Overall, experiencing CSC was positively associated with momentary BPD symptoms. Thus, both the FFM and CSC were associated with BPD patients' experience of symptoms in everyday life. Furthermore, specific FFM trait domains were particularly impactful in contexts where BPD symptoms are more likely to be manifested, providing further evidence that person-by-situation interactions are important for understanding BPD symptoms in the moment.

Determining optimal diagnostic criteria through chronicity and comorbidity

Purpose

Contemporary approaches to clinical diagnosis have not adequately exploited state-of-the-art empirical techniques in deriving diagnostic criterion sets that are statistically optimal based on 1) relevant external indicators and 2) replicability across data sets. We provide a proof of concept that optimal criterion sets can be derived with respect to alcohol use disorder (AUD) diagnosis that are both more efficient and precise than current systems.

Methods

Using data from the National Epidemiologic Survey on Alcohol and Related Conditions we selected chronicity (i.e. persistence) of AUD diagnosis and comorbidity of AUD with other disorders as validation criteria on which to optimize the size of the AUD criterion set and the threshold for AUD diagnosis. We used cross-validation and consensus approaches for choosing a final solution.

Results

Cross-validation did not produce a solution that replicated across random subsamples or differed from conventional diagnosis. Alternatively, consensus produced a more global solution that was associated with greater validity than “conventional” diagnosis.

Conclusion

Such methods, if applied to extant diagnostic criteria and algorithms can generate simpler and more reliable rules and hold promise for greatly reducing misclassification of individuals in both research and applied clinical contexts.

Undifferentiated negative affect and impulsivity in borderline personality and depressive disorders: A momentary perspective

Individuals with borderline personality disorder (BPD) often report experiencing several negative emotions simultaneously, an indicator of "undifferentiated" negative affect. The current study examined the relationship between undifferentiated negative affect and impulsivity. Participants with a current BPD (n = 67) or depressive disorder (DD; n = 38) diagnosis carried an electronic diary for 28 days, reporting on emotions and impulsivity when randomly prompted (up to 6 times per day). Undifferentiated negative affect was quantified using momentary intraclass correlation coefficients, which indicated how consistently negative emotion items were rated across fear, hostility, and sadness subscales. Undifferentiated negative affect at the occasion-level, day-level, and across 28 days was used to predict occasion-level impulsivity. Multilevel modeling was used to test the hypothesis that undifferentiated negative emotion would be a significant predictor of momentary impulsivity above and beyond levels of overall negative affect. Undifferentiated negative affect at the occasion and day levels were significant predictors of occasion-level impulsivity, but undifferentiated negative affect across the 28-day study period was only marginally significant. Results did not differ depending on BPD or DD status, though individuals with BPD did report significantly greater momentary impulsivity and undifferentiated negative affect. Undifferentiated negative affect may increase risk for impulsivity among individuals with BPD and depressive disorders, and the current data suggest that this process can be relatively immediate as well as cumulative over the course of a day. This research supports the consideration of undifferentiated negative affect as a transdiagnostic construct, but one that may be particularly relevant for those with BPD.

Affective Dynamics in Psychopathology

We discuss three varieties of affective dynamics (affective instability, emotional inertia, and emotional differentiation). In each case, we suggest how these affective dynamics should be operationalized and measured in daily life using time-intensive methods, like ecological momentary assessment or ambulatory assessment, and recommend time-sensitive analyses that take into account not only the variability but also the temporal dependency of reports. Studies that explore how these affective dynamics are associated with psychological disorders and symptoms are reviewed, and we emphasize that these affective processes are within a nexus of other components of emotion regulation.

Limits of Current Approaches to Diagnosis Severity Based on Criterion Counts: An Example with DSM-5 Alcohol Use Disorder

Within DSM-5, some diagnoses are now associated with a severity gradient based on the number of diagnostic criteria satisfied. Reasons for questioning the validity of this approach include the implicit assumptions of equal criterion severity and strict additivity of criteria combinations. To assess the implications of heterogeneity of criterion configurations on severity grading, we examined the association between all observed combinations of DSM-5 alcohol use disorder criteria endorsement, at each level of number of criteria endorsed, and multiple validity measures among 22,177 past-year drinkers from Wave 2 of the NESARC. Substantial variability of implied severity across criteria combinations was observed at each level of endorsement, with nontrivial overlap in implied severity across criterion counts. Findings suggest severity indices are at best imprecise and, potentially, misleading. These problems are likely inherent in traditional polythetic approaches to diagnosis and almost certainly applicable to other disorders. Approaches for improving severity grading are proposed.
