The role of positive affect processes in the association between posttraumatic stress disorder symptoms and sleep: A multi-study design.

OBJECTIVES: Posttraumatic stress disorder (PTSD) symptoms have been linked to sleep disturbances. Limited work has explored how positive affect processes may account for this relationship. Advancing research in this area, we utilized a multi-study design to investigate the role of positive affect processes (levels of positive affect, positive emotionality, hedonic deficits, negative affect interference) in the PTSD-sleep association. METHODS: Data from 149 trauma-exposed firefighters (Mage = 38.93 ± 9.65, 5.40 % women) were collected between September 2021 and November 2021, and data from 119 trauma-exposed community members (Mage = 29.60 ± 8.67, 68.10 % women) were collected between February 2021 and December 2021. Participants completed an online survey on PTSD symptoms, sleep disturbances, and positive affect processes. RESULTS: Positive affect levels (b = 0.03, 95 % confidence interval [CI] [0.01, 0.06]; firefighter sample), positive emotionality (b = 0.07, CI [0.03, 0.13]; community sample), and negative affect interference (b = 0.06, CI [0.01, 0.14]; community sample) significantly accounted for the associations between PTSD symptom severity and sleep disturbances controlling for the effects of gender and age. CONCLUSION: Findings highlight the role of positive affect processes in the link between PTSD and sleep, and support addressing positive affect processes as potential targets in clinical interventions for co-occurring PTSD-sleep problems.

Cross-cultural investigation from nine countries on the associations of antisocial traits and the WHO's containment measures for the COVID-19 pandemic.

Personality traits play a role in prosocial behavior in relation to containment measures intended to tackle the COVID-19 pandemic. Empirical findings indicated that individuals high in socially aversive traits such as callousness are less compliant with containment measures. This study aimed to add cross-cultural data on the relationship between antisocial traits and adherence to COVID-19 containment measures. The sample consisted of 4,538 adults recruited by convenience in nine countries (Australia, Brazil, England, Iraq, Iran, Italy, Jordan, Saudi Arabia, and the United States). Statistical analyses indicated two latent profiles from our sample, empathic and antisocial, and six COVID-19 containment-measure-related factors using measures covering antisocial traits (PID-5), empathy (ACME), global personality pathology (LPFS-BF), and COVID-19 behaviors and beliefs. Through MANCOVA, the antisocial profile consistently showed less compliance and concern about the COVID-19 containment measures, even when controlling for demographics and local pandemic covariables. The network analysis indicated a lack of empathy and callousness as crucial traits of the predisposition to non-compliant behavior. In elaborating on prosocial campaigns in community emergencies, our cross-cultural findings would need to consider personality traits that focus on antisociality, anticipating similar associations and potential impacts in future disease outbreaks.

Factors Associated With Highest Symptoms of Anxiety During COVID-19: Cross-Cultural Study of 23 Countries.

The COVID-19 restrictions have impacted people's lifestyles in all spheres (social, psychological, political, economic, and others). This study explored which factors affected the level of anxiety during the time of the first wave of COVID-19 and subsequent quarantine in a substantial proportion of 23 countries, included in this study. The data was collected from May to August 2020 (5 June 2020). The sample included 15,375 participants from 23 countries: (seven from Europe: Belarus, Bulgaria, Croatia, Hungary, Italy, Romania, Russia; 11 from West, South and Southeast Asia: Armenia, India, Indonesia, Iran, Iraq, Jordan, Malaysia, Pakistan, Saudi Arabia, Thailand, Turkey; two African: Nigeria and Tanzania; and three from North, South, and Central America: Brazil, Canada, United States). Level of anxiety was measured by means of the 7-item Generalized Anxiety Disorder Scale (GAD-7) and the 20-item first part of The State-Trait Anxiety Inventory (STAI)-State Anxiety Inventory (SAI). Respondents were also asked about their personal experiences with COVID-19, attitudes toward measures introduced by governments, changes in attitudes toward migrants during a pandemic, family income, isolation conditions, etc. The factor analysis revealed that four factors explained 45.08% of variance in increase of anxiety, and these components were interpreted as follows: (1) personal awareness of the threat of COVID-19, (2) personal reaction toward officially undertaken measures and attitudes to foreigners, (3) personal trust in official sources, (4) personal experience with COVID-19. Three out of four factors demonstrated strong associations with both scales of anxiety: high level of anxiety was significantly correlated with high level of personal awareness of the threat of COVID-19, low level of personal reaction toward officially undertaken measures and attitudes to foreigners, and high level of presence of personal experience with COVID-19. Our study revealed significant main effects of sex, country, and all four factors on the level of anxiety. It was demonstrated that countries with higher levels of anxiety assessed the real danger of a pandemic as higher, and had more personal experience with COVID-19. Respondents who trusted the government demonstrated lower levels of anxiety. Finally, foreigners were perceived as the cause of epidemic spread.

Examining indirect effects of emotion dysregulation between PTSD symptom clusters and reckless/self-destructive behaviors.

OBJECTIVES: Emotion dysregulation theoretically and empirically explains the link between posttraumatic stress disorder (PTSD) and posttrauma reckless and self-destructive behaviors (RSDBs). METHOD: The current study uniquely examined the role of emotion dysregulation in the association between the four heterogeneous PTSD clusters (intrusions, avoidance, negative alterations in cognitions and mood [NACM], and alterations in arousal and reactivity [AAR]) and an overall measure of posttrauma RSDBs. Trauma-exposed participants (n = 411) completed self-report measures assessing PTSD symptoms (PTSD Checklist for DSM-5), emotion dysregulation (Difficulties in Emotion Regulation Scale-16), and engagement in RSDBs (Posttrauma Risky Behaviors Questionnaire). RESULTS: Direct and indirect effects were examined using PROCESS Model 4. The bias-corrected bootstrap revealed a significant indirect effect of emotion dysregulation in posttrauma RSDBs' relation with PTSD's intrusions (B = -.13, SE = .04, 95% CI [-.23, -.06]), avoidance (B =.15, SE =.07, 95% CI [.04, .33]), NACM (B =.17, SE =.05, 95% CI [.09, .27]), and AAR (B =.14, SE =.05, 95% CI [.05, .27]). CONCLUSIONS: Emotion dysregulation explained associations between the severity of each PTSD symptom cluster and overall posttrauma RSDBs. PTSD treatments targeting emotion dysregulation may help to reduce posttrauma RSDBs for trauma-exposed individuals. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Moderating effects of sleep difficulties on relations between posttraumatic stress disorder symptoms and positive memory count.

OBJECTIVES: Posttraumatic stress disorder (PTSD) severity relates to positive memory retrieval difficulties. One variable potentially influencing this relation is sleep difficulties. We examined moderating effects of sleep difficulties (duration and quality) on relations between PTSD severity and count of specific positive memories covarying for age, gender, and depression. METHODS: Participants were an Amazon Mechanical Turk-recruited trauma-exposed community sample of 205 respondents (M age = 35.44; 61.40% women). RESULTS: Moderated regression analyses indicated significant interaction effects between sleep quality (b = 0.03; p = 0.036) and PTSD severity on specific positive memory count. Among individuals reporting better sleep quality, there were negative associations between PTSD severity and specific positive memory count (b = -0.04, SE = 0.02, p = 0.010). Similar results were obtained for PTSD's intrusion and arousal clusters. CONCLUSION: Results support targeting sleep quality and PTSD severity to improve positive memory retrieval in PTSD and memory interventions, and the importance of considering sleep when examining links between PTSD and positive memory retrieval.

Excessive reassurance seeking mediates relations between rumination and problematic smartphone use.

Aside from depression and anxiety, less is known about the relationship of problematic smartphone use (PSU) to other psychopathology- related variables. The authors' aim was to test previously neglected variables in relation to PSU: rumination and excessive reassurance seeking behavior (ERSB). The authors recruited 295 college students for a web-based survey of smartphone use frequency, PSU, depression and anxiety, ruminative thinking, and ERSB. The authors tested linear regression and mediation models, assessing rumination and ERSB as mediating associations between depression/anxiety severity with PSU, adjusting for age, sex, and smartphone use frequency. Results demonstrate that ERSB was significantly related to PSU severity, and ERSB mediated the association between rumination and PSU. Furthermore, the combination of rumination and ERSB mediated relations between both depression and anxiety severity with PSU. Results provide evidence for ERSB as an important variable in understanding relationships between psychopathology symptoms and PSU severity among college students.

Worry and anger are associated with latent classes of problematic smartphone use severity among college students.

BACKGROUND: Problematic smartphone use (PSU) is associated with depression and anxiety symptom severity throughout the literature. However, many important psychopathology constructs have not been examined for associations with PSU severity. Worry and anger are two psychopathology constructs receiving little empirical scrutiny in relation to PSU, but theoretically should demonstrate significant relationships. Furthermore, few studies have used person-centered analyses, such as mixture modeling, to analyze possible latent subgroups of individuals based on PSU symptom ratings. METHOD: We conducted a web survey of 300 American college students, using the Smartphone Addiction Scale-Short Version, Penn State Worry Questionnaire-Abbreviated Version, and Dimensions of Anger Reactions-5 Scale. RESULTS: Conducting mixture modeling using latent profile analysis, we found most support for a three-class model of latent groups of individuals based on their PSU item ratings. Adjusting for age and sex, worry and anger scores were significantly higher in the more severe PSU classes. DISCUSSION: Results are discussed in the context of uses and gratifications theory, as well as compensatory internet use theory, in terms of individual differences explaining excessive technology use. LIMITATIONS: Limitations include the non-clinical nature of the sample. CONCLUSIONS: Worry and anger may be helpful constructs in understanding the phenomenology of PSU, and psychological interventions for worry and anger may offset PSU.

Global Study of Social Odor Awareness.

Olfaction plays an important role in human social communication, including multiple domains in which people often rely on their sense of smell in the social context. The importance of the sense of smell and its role can however vary inter-individually and culturally. Despite the growing body of literature on differences in olfactory performance or hedonic preferences across the globe, the aspects of a given culture as well as culturally universal individual differences affecting odor awareness in human social life remain unknown. Here, we conducted a large-scale analysis of data collected from 10 794 participants from 52 study sites from 44 countries all over the world. The aim of our research was to explore the potential individual and country-level correlates of odor awareness in the social context. The results show that the individual characteristics were more strongly related than country-level factors to self-reported odor awareness in different social contexts. A model including individual-level predictors (gender, age, material situation, education, and preferred social distance) provided a relatively good fit to the data, but adding country-level predictors (Human Development Index, population density, and average temperature) did not improve model parameters. Although there were some cross-cultural differences in social odor awareness, the main differentiating role was played by the individual differences. This suggests that people living in different cultures and different climate conditions may still share some similar patterns of odor awareness if they share other individual-level characteristics.
