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.

Anxiety about COVID-19 Infection, and Its Relation to Smartphone Addiction and Demographic Variables in Middle Eastern Countries.

This study explores the level and frequency of anxiety about COVID-19 infection in some Middle Eastern countries, and differences in this anxiety by country, gender, workplace, and social status. Another aim was to identify the predictive power of anxiety about COVID-19 infection, daily smartphone use hours, and age in smartphone addiction. The participants were 651 males and females from Jordan, Saudi Arabia, the United Arab Emirates, and Egypt.

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 ( = 411) completed self-report measures assessing PTSD symptoms (PTSD Checklist for -5), emotion dysregulation (Difficulties in Emotion Regulation Scale-16), and engagement in RSDBs (Posttrauma Risky Behaviors Questionnaire).

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.

National, Sex and Academic Discipline Difference in Smartphone Addiction: A Study of Students in Jordan, Saudi Arabia, Yemen and Sudan.

There are an increasing number of studies on smartphone addiction (SA) among students, and also a number of cross-cultural ones. We add to this body of research by presenting, for the first time, a cross-cultural study comparing students in four Middle Eastern countries: Sudan, Jordan, Saudi Arabia, and Yemen. In this context, we also attempt to replicate findings-in other studies-that there are differences in smartphone addiction prevalence along the lines of sex, culture and subject of study.

SEX DIFFERENCES ON THE WISC-III AMONG CHILDREN IN SUDAN AND THE UNITED STATES.

The sex differences on the WISC-III are reported for the thirteen subtests, the Verbal and Performance IQs, the four Index IQs and the Full Scale IQs in Sudan and the United States. The sex differences are closely similar in the two samples with a correlation of 0.878 (p<0.
