Latent Profiles of Sleep Disturbance and Impairment in Elementary School-Age Youth: Concurrent and Longitudinal Associations with Emotional, Behavioral, and Academic Functioning

OBJECTIVE

The links from youth sleep problems to emotional, behavioral, and academic functioning are well documented. Latent variable mixture modeling (LVMM) has been used to explore these relations; however, additional research is needed in diverse samples and with self-reports of sleep-related difficulties. The objectives of the current study were to identify profiles based on patterns of sleep disturbance and impairment and explore associations among profiles and functioning at baseline and over a subsequent 6-month period.

METHODS

Participants were 278 third- through fifth-grade students (M age = 9.27; 51.8% male; 51.1% Hispanic/Latine) and homeroom teachers. Children completed measures of sleep disturbance and impairment, emotion (dys)regulation, and depressive, anxiety, and anger symptoms. Teachers completed measures of youth's emotional and conduct problems, emotion (dys)regulation, and academic performance. LVMM was conducted.

RESULTS

Three profiles emerged: (1) "Average Sleep Disturbance and Impairment" (n = 148); (2) "Elevated Sleep Disturbance and Average Sleep Impairment" (n = 40); and (3) "Elevated Sleep Disturbance and Impairment" (n = 90). Overall, youth with above average sleep problems had worse functioning at baseline. Further, youth in Profile 3 exhibited increases in self-reported symptoms of depression, anxiety, and anger, as well as worsening teacher-reported academic performance and conduct problems. In contrast, youth in Profile 2 exhibited improvements in self-reported symptoms of depression, anxiety, and anger, as well as teacher-reported emotion regulation, conduct problems, and academic performance.

CONCLUSIONS

Results highlight the importance of examining self-reports of sleep problems and the need for intervention among children exhibiting elevated sleep disturbance and impairment.

Self-Efficacy and External Locus of Control as Predictors of Participant Roles in Relational Aggression

We examined the extent to which the perceived behavioral control factors of pro-social, emotional, or verbal-social self-efficacy (SE) as well as external locus of control (LOC) explain the variance between different participant roles: relational aggressors, relational victims, relational aggressive-victims, and bystanders. Participants included 1,518 adolescents (61.6% boys and 38.4% girls) from 15 Israeli middle and high schools. Multinomial logistic regression models indicated relational aggressors, and aggressive-victims had lower pro-social SE and higher verbal-social SE than relational victims and bystanders. Relational aggressors, aggressive-victims, and victims had more extensive external LOC than bystanders. The theoretical contribution of verbal-social SE is discussed, and practical implications are highlighted, in particular, regarding the relational aggressive-victim, who exhibits high-risk behaviors.
