Study objectives New theory and measurement approaches have facilitated nuanced investigation of how sleep loss impacts dimensions of affective functioning. To provide a quantitative summary of this literature, three conceptually related meta-analyses examined the effect of sleep restriction and sleep deprivation on mood, emotion, and emotion regulation across the lifespan (i.e., from early childhood to late adulthood). Method A total of 241 effect sizes from 64 studies were selected for inclusion, and multilevel meta-analytic techniques were used when applicable. Results There was a moderate, positive effect of sleep loss on negative mood (g = .45), which was stronger for studies with younger samples, as well as a large, negative effect of sleep loss on positive mood (g = -.93); type of sleep manipulation (i.e., restriction or deprivation) did not moderate either effect. After correcting for publication bias, a modest but significant negative effect emerged for the effect of sleep on emotion (g = .11); the valence of emotional stimuli did not change the direction of this effect, and type of sleep manipulation was also not a significant moderator. Finally, sleep restriction had a small, negative effect on adaptive emotion regulation (g = -.32), but no significant impact on maladaptive emotion regulation (g = .14); all studies on adaptive emotion regulation were conducted with youth samples. Conclusions Sleep loss compromises optimal affective functioning, though the magnitude of effects varies across components. Findings underscore the importance of sleep for healthy affective outcomes.
Depression and anxiety are prevalent and impairing forms of psychopathology in children and adolescents. Deficits in early executive control (EC) may contribute to the development of these problems, but longitudinal studies with rigorous measurement across key developmental periods are limited. The current study examines EC in preschool as a predictor of subsequent depression and anxiety symptoms in elementary school in a community sample (N = 280). Child participants completed a battery of nine developmentally-appropriate tasks designed to measure major aspects of EC at age 5 years, 3 months. Children later participated in an elementary school follow-up phase, during which they completed validated norm-referenced self-report questionnaires of depression and anxiety symptoms in fourth grade. Results indicate that poorer preschool EC was significantly associated with both greater depression and anxiety symptoms in elementary school, controlling for baseline depression and anxiety symptoms in preschool and other relevant variables. These findings suggest that poor EC may be an important risk factor for the development of internalizing psychopathology in childhood. Given emerging evidence for the modifiability of EC, particularly in preschool, EC promotion interventions may hold promise as a potential target in psychopathology prevention.
Many college students, are susceptible to alcohol use and related problems, including Hispanic and Asian Americans. A potential factor contributing to this risk is acculturation, which can be defined as the process of psychological, behavioral, social, and cultural change and adaptation that occurs when individuals or groups from different cultural backgrounds come in contact. This chapter provides a narrative review of the literature examining acculturation and alcohol use among these populations. One key theme to emerge from this review is that the exact direction of the association between these variables is unclear and therefore should be considered with caution. While the existing evidence is relatively limited, gender and, to some extent, ethnic group membership appear to moderate the association between acculturation and alcohol use. Several methodological issues pertaining to the study of acculturation, future research directions, and implications for intervention and prevention are discussed.
Playing drinking games can be characterized as a high-risk drinking activity because games are typically designed to promote heavy alcohol consumption. While research suggests that young adults are motivated to play drinking games for a variety of reasons (e.g., for thrills/fun, for the competition), the Motives for Playing Drinking Games measure has received limited empirical attention. We examined the psychometric properties of this measure with a confirmation sample of young adults recruited from Amazon’s MTurk (N = 1,809, ages 18–25 years, 47% men; 41% not currently enrolled in college) and a validation sample of college students (N = 671; ages 18–23 years; 26% men). Contrary to the 8-factor model obtained by Johnson and Sheets in a study published in 2004, examination of the factor structure with our confirmation sample yielded a revised 7-factor model that was invariant across race/ethnicity and college student status. This model was also validated with the college student sample. In the confirmation sample, enhancement/thrills and sexual pursuit motives for playing drinking games were positively associated with gaming frequency/consumption and negative gaming consequences. Furthermore, conformity motives for playing drinking games were positively associated with negative gaming consequences, while competition motives were positively associated with gaming frequency. These findings have significant implications for research and prevention/intervention efforts.
Racism-related stress is thought to contribute to widespread race/ethnic health inequities via negative emotion and allostatic stress process up-regulation. Although prior studies document race-related stress and health correlations, due to methodological and technical limitations, they have been unable to directly test the stress-reactivity hypothesis in situ. Guided by theories of constructed emotion and allostasis, we developed a protocol using wearable sensors and daily surveys that allowed us to operationalize and time-couple self-reported racism-related experiences, negative emotions, and an independent biosignal of emotional arousal. We used data from 100 diverse young adults at a predominantly White college campus to assess racism-related stress reactivity using electrodermal activity (EDA), a biosignal of sympathetic nervous system activity. We find that racism-related experiences predict both increased negative emotion risk and heightened EDA, consistent with the proposed allostatic model of health and disease. Specific patterns varied across race/ethnic groups. For example, discrimination and rumination were associated with negative emotion for African American students, but only interpersonal discrimination predicted increased arousal via EDA. The pattern of results was more general for Latinx students, for whom interpersonal discrimination, vicarious racism exposure, and rumination significantly modulated arousal. As with Latinx students, African students were particularly responsive to vicarious racism while 1.5 generation Black students were generally not responsive to racism-related experiences. Overall, these findings provide support for allostasis-based theories of mental and physical health via a naturalistic assessment of the emotional and sympathetic nervous system responding to real-life social experiences.
