Objective: The goal of the current study was to better understand affect-drinking relations among those diagnosed with an alcohol use disorder (AUD), as recent meta-analytic work suggests that daily negative affect may not universally predict subsequent alcohol consumption in those nondependent on alcohol. Specifically, we investigated the between- and within-person effects of positive and negative affects on drinking.

Method: Participants (n = 92) who met AUD diagnostic criteria completed a 90-day daily assessment of drinking behavior and positive and negative affects.

Results: Time-lagged multilevel modeling revealed that within-person elevations in negative affect predicted increased odds and quantity of drinking later in the day. Relations between positive affect and drinking were nonsignificant.

Conclusions: These findings are in contrast to recent meta-analytic findings and highlight the complexity of affect-drinking relations among those diagnosed with AUD. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Cognitive theories of depression posit that maladaptive information processing increases the risk for depression recurrence. There is increasing theoretical and empirical support for the cognitive control of emotional information as a vulnerability factor for depression recurrence. In this investigation, findings from behavioral studies that compared the cognitive control of emotional information between participants with remitted major depressive disorder (rMDD) and healthy control (HC) participants were examined. Response times (RTs) and error rates were used as outcome variables, and aspects of clinical features, sample characteristics, and methodology and design were examined as moderating variables. The final review included 44 articles with a total of 2,081 rMDD participants and 2,285 HC participants. The two groups significantly differed in the difference score between RTs for negative and positive stimuli. Specifically, the difference in RTs between negative and positive stimuli was larger in participants with rMDD than in HC participants, indicating greater difficulty controlling irrelevant negative (vs. positive) stimuli in rMDD. Such cognitive control bias may be associated with preferential processing of negative over positive information in working memory. This imbalance may then be linked to other emotional information processing biases and emotion dysregulation, thereby increasing the risk for depression recurrence. Implications, limitations, and future directions are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Appearance dissatisfaction and depressive symptoms are considered key risk factors of disordered eating. However, their etiological status is equivocal; previous longitudinal studies have not accounted for time-invariant confounding effects and have not considered potential reverse temporal influences. In addition, whether associations differ between developmental periods and genders has remained untested. To address these issues, we employed a nationwide sample of Norwegian adolescents (N = 2,933; M_age = 15.4 years, 54.2% women) assessed at five time points until midlife. Random-intercept cross-lagged panel models were used to examine the prospective associations between appearance dissatisfaction, depressive symptoms, and disordered eating, net of all unmeasured time-invariant confounding effects. Results showed that high levels of appearance dissatisfaction and depressive symptoms significantly predicted increased disordered eating. Conversely, disordered eating was also a predictor of increased appearance dissatisfaction and depressive symptoms. These reciprocal effects were equal in magnitude across developmental periods and gender. These results suggest that successful interventions to reduce appearance dissatisfaction and depressive symptoms may alleviate disordered eating, while reduced disordered eating may have beneficial effects on appearance dissatisfaction and depressive symptoms, regardless of age or gender.

Prospective studies have found inconsistent relations between social support deficits and future increases in eating disorder symptoms. Furthermore, no prospective study has tested whether elevated eating disorder symptoms predict a future erosion of social support. Accordingly, the current study investigated the prospective reciprocal relations between perceived social support from both parents and peers and eating disorder symptoms in adolescent girls. In this study, 496 adolescent girls reported perceived social support and completed an eating disorder diagnostic interview annually for 7 years. Deficits in perceived peer, but not parental, support predicted future increases in eating disorder symptoms (p = .019, partial r = -.10). Furthermore, initial eating disorder symptoms predicted future reductions in perceived peer support (p = .016, partial r = -.11) but not parental support. Interestingly, these relations became nonsignificant when we controlled for negative affect and body mass index, suggesting that comorbid mood disorders and elevated body weight might partially drive these relations. Although both relations were small in magnitude, these results suggest low perceived peer support is a risk factor for future escalations in eating disorder symptoms and that elevated symptoms may contribute to a further erosion of peer support, creating a cyclical relation that maintains eating pathology. Conversely, high levels of perceived peer support could serve as a protective factor against future increases in eating pathology. These findings should advance interpersonal theories of eating pathology and inform the design of more effective prevention programs. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Introduction: Symptoms of prolonged grief disorder (PGD), depression, and posttraumatic stress disorder (PTSD) often emerge concurrently in bereavement. The understanding of temporal relationships between these syndromes in a general bereaved population is limited. This study aims to investigate temporal relationships between these syndromes from 2 months postloss throughout the two first years of bereavement.

Method: Data were derived from a registry-based cohort study with 1,224 adult participants, who lost a spouse or parent. Participants completed self-report measures of PGD, depression, and PTSD at 2, 6, 11, 18, and 26 months postloss. Random intercept cross-lagged panel analyses examined the temporal relationships between PGD, PTSD, and depression.

Results: In spousal and parental bereavement, high levels of grief symptoms at 2 months postloss predicted subsequent high symptoms of PTSD and depression at 6 months postloss, not vice versa. PGD, PTSD, and depression showed strong intertwined relationships over the two first years of bereavement. Between-person differences explained an increasingly large amount of variance in symptoms of PGD, PTSD, and depression over time. Losing a spouse and younger age was associated with higher symptoms of PGD, PTSD, and depression compared to losing a parent and older age.

Conclusion: In the early years of bereavement, large differences exist between bereaved individuals in general levels of PGD, PTSD, and depression. Within bereaved individuals, the temporal relationships between these syndromes become increasingly complex and intertwined over time. Findings should be interpreted with respect to the nonclinical sample and self-report data used. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Deficits in emotion processing are core features of psychotic disorders. Electrophysiology research in schizophrenia suggests deficits in sustained engagement with emotional content (indexed by the late positive potential [LPP]) may contribute to emotion processing impairments. Despite similar behavioral emotion processing dysfunction in those at clinical high risk (CHR) for psychosis, limited research has examined neural mechanisms of impaired emotion processing in the high-risk period, where research can inform risk models. To examine mechanisms of emotion processing deficits in those at CHR for psychosis, the present study used a passive viewing task to elicit the LPP in response to emotionally engaging and neutral stimuli in 28 CHR and 32 control participants (60% female). Relative to controls, CHR participants showed reduced LPP amplitude when viewing unpleasant images (d = 0.75, p = .005) but similar LPP amplitude in response to both neutral (d = 0.35, p = .19) and pleasant images (d = 0.31, p = .24). This pattern suggests that individuals at CHR for psychosis exhibit a deficit in sustained engagement with unpleasant stimuli. Clinical and trait questionnaires were administered to examine potential exploratory explanations for group differences in LPP amplitude. Consistent with evidence suggesting LPP amplitude reflects engagement of approach/avoidance motivational systems, greater LPP amplitude was associated with greater trait-level behavioral avoidance in control participants (r = .42, p = .032) but not CHR participants (r = -.21, p = .40). Together, the present research is consistent with LPP studies in psychosis and implicates reduced sustained engagement with emotional content in the high-risk period.

The current study used novel methodology to characterize intraindividual variability in the experience of dynamic, within-person changes in postpartum depressive (PPD) symptoms across the first year postpartum and evaluated maternal and infant characteristics as predictors of between-person differences in intraindividual variability in PPD symptoms over time. With a sample of 322 low-income Mexican-origin mothers (Mage = 27.79; SD = 6.48), PPD symptoms were assessed at 11 time points from 3 weeks to 1 year postpartum (Edinburgh Perinatal Depression Scale; Cox & Holden, 2003). A prenatal cumulative risk index was calculated from individual psychosocial risk factors. Infant temperamental negativity was assessed via a maternal report at the infant age of 6 weeks (Infant Behavior Questionnaire; Putnam et al., 2014). Multilevel location scale analyses in a dynamic structural equation modeling (Asparouhov et al., 2018) framework were conducted. Covariates included prenatal depressive symptoms. On average, within-mother change in depressive symptoms at one time point was found to carry over to the next time point. Nonnull within-mother volatility in PPD symptoms reflected substantial ebbs and flows in PPD symptoms over the first year postpartum. Results of the between-level model demonstrated that mothers differed in their equilibriums, carryover, and volatility of their PPD symptoms. Mothers with more negative infants and those with higher prenatal cumulative risk exhibited higher equilibriums of PPD symptoms and more volatility in symptoms but did not differ in their carryover of PPD symptoms.

The Diagnostic and Statistical Manual of Mental Disorders (DSM) descriptive criterial approach to diagnosis has been criticized for contributing to comorbidity, heterogeneity within conditions, and nonspecificity across conditions. Much research has examined comorbidity and heterogeneity, but less is known about nonspecificity. Here, we examined two nonspecific symptoms: irritability and sleep disturbance. Both are common, clinically significant, and appear in several DSM disorder criteria sets, but their transdiagnostic prevalence is unknown. Leveraging a nationally representative epidemiological study of adolescents (n = 10,148; ages = 13-18), we first identified all instances where irritability or sleep disturbance appears in DSM-5-TR criteria for bipolar, depressive, anxiety, traumatic stress, or disruptive/impulse-control disorders; then found their DSM-IV equivalents in study variables; and finally estimated their prevalence individually and cumulatively across categories. Weighted lifetime prevalence estimates were 79.5% (95% CI [77.8, 81.2]) for irritability and 60.8% [58.7, 62.9] for sleep disturbance. Associations with age and gender were significant but small. Most youth reported multiple symptoms of irritability (weighted M = 3.04, Mdn = 2) and at least one symptom of sleep disturbance (weighted M = 1.61, Mdn = 1). Both problems were extremely common among individuals with specific disorders but were underestimated by the criteria for those conditions. Results suggest that the high prevalence of DSM-defined irritability and sleep problems may be obfuscated by these symptoms being scattered across diagnostic entities. There is a need for more research on assessing, treating, and understanding problems related to irritability and sleep in their own right, cutting across, rather than confined to, particular diagnoses.
