A person-centered analysis of sleep and emotion dysregulation: Short- and long-term links with depression and alcohol use.

Objective: Our objective was to examine the co-occurrence of sleep problems and emotion dysregulation and its short- and long-term links to depressive symptoms and alcohol use in a sample of university students. Method: Participants included 1132 first-year university students from Southern Ontario (70.5% women). Time 1 data were collected in February/March, 2010, and Time 2 data (n = 746) were collected in February/March, 2014. Participants were surveyed about sleep problems and emotion dysregulation (Time 1), and depressive symptoms and alcohol use (Times 1 and 2). Results: A latent class analysis revealed four groups: (1) Low Co-Occurrence, (2) Sleep Problems Only, (3) Emotion Dysregulation Only, and (4) High Co-occurrence. Group 4 had more depressive symptoms than all other groups in both the short- and long-term. Conclusions: First year university students with high co-occurrence of sleep problems and emotion dysregulation may be a target group for programs focused on reducing adjustment difficulties.

Long-Term Links between Physical Activity and Sleep Quality.

PURPOSE: Findings from cross-sectional research indicate that the relationship between sleep quality and physical activity is mixed. For research that does indicate a significant association, the interpretation of the finding most often is that physical activity leads to better sleep, or less frequently, that better sleep leads to more involvement in physical activity (see sleep deprivation studies). Cross-sectional studies, however, are not able to assess the direction of these effects, and experimental studies have tested only one direction of the effects. Longitudinal studies, with their focus on temporal order, are needed to specifically examine the link between sleep and physical activity as well as the direction of effects. The current study had three goals: to examine 1) the longitudinal relationship between sleep and physical activity, 2) the direction of effects, and 3) whether emotion regulation mediates the relationship between sleep and physical activity. METHODS: Participants included a sample of 827 (Mage at baseline = 19.04 yr, SD = 0.92 yr, 73.88% female) students at a university in Southwestern Ontario, who took part in a larger longitudinal survey that started in their first year of university. Participants were surveyed annually for 3 yr (2011, 2012, 2013; retention, 83.9%). Measures assessed sleep quality, physical activity, emotion regulation, and involvement in sports clubs. RESULTS: A cross-lagged autoregressive path analysis revealed that sleep quality indirectly predicted increased high-, moderate-, and low-intensity physical activity over time through its positive effect on emotion regulation. Moderate levels of physical activity indirectly predicted sleep quality over time through emotion regulation. CONCLUSIONS: Overall, there appears to be support for a bidirectional relationship between sleep and physical activity over time (at least for moderate physical activity) but only indirectly through emotion regulation.

Psychosocial Adjustment Throughout University: A Longitudinal Investigation of the Roles of Sleep Quality and Emotion Dysregulation.

Sleep problems and emotion dysregulation are associated with depressive symptoms and alcohol use but little research has examined the long-term associations and the direction of effects between these factors. We examined these relationships with 1132 undergraduates (70.5% female) over 5 years. Sleep problems and emotion dysregulation, sleep problems and depressive symptoms, and emotion dysregulation and depressive symptoms were all related bidirectionally. Tests of indirect effects indicated that sleep problems predicted depressive symptoms over time (and vice versa) via emotion dysregulation and emotion dysregulation predicted depressive symptoms over time (and vice versa) via sleep problems. The results highlight the need to assess direction of effects, given that many factors that are typically seen as "predictors" also can be framed as "outcomes".

Attentional biases and recognition accuracy: What happens when multiple own- and other-race faces are encountered simultaneously?

Adults recognize own-race faces more accurately than other-race faces. We investigated three characteristics of laboratory investigations hypothesized to minimize the magnitude of the own-race recognition advantage (ORA): lack of competition for attention and instructions that emphasize individuating faces during the study phase, and a lack of uncertainty during the test phase. Across two experiments, participants studied faces individually, in arrays comprising multiple faces and household objects, or in naturalistic scenes (presented on an eye-tracker); they were instructed to remember everything, memorize faces, or form impressions ofpeople. They then completed one of two recognition tasks--an old/new recognition task or a lineup recognition task. Task instructions influenced time spent looking at faces but not the allocation of attention to own- versus other-race faces. The magnitude of the ORA was independent of both task instructions and test protocol, with some modulation by how faces were presented in the study phase. We discuss these results in light of current theories of the ORA.

Religious and Non-religious Activity Engagement as Assets in Promoting Social Ties Throughout University: The Role of Emotion Regulation.

Emerging adulthood is a time of many changes. For example, one change that occurs for a subset of emerging adults is leaving home and starting university. Importantly, the creation of social ties can aid in promoting positive adjustment during university. This study investigated whether involvement in religious activities promotes social ties among university students directly and/or indirectly through emotion regulation. Importantly, involvement in religious activities may promote self-regulatory skills, and the ability to effectively regulate emotions can aid in navigating social interactions. To rule out potentially important confounding variables, spirituality and involvement in non-religious clubs were statistically controlled in all analyses. The participants included 1,132 university students (70.5 % female) from a university in Ontario, Canada who were surveyed each year over a period of 3 years. The results indicated that involvement in religious activities indirectly predicted more social ties over time through emotion regulation. Spirituality did not predict social ties or emotion regulation. Furthermore, non-religious clubs directly predicted more social ties over time. Thus, although involvement in religious and non-religious activities both predicted more social ties in a university setting over time, the mechanism by which these activities promote social ties differed.
