Objective To examine associations between sociodemographic factors (single parenthood, family income, education level, race), stress, and psychological distress among pediatric cancer patients and their mothers. Methods Participants completed measures assessing sociodemographic variables, depressive symptoms, posttraumatic stress symptoms, general stress, and cancer-related stress within the first year of the child’s (ages 5–17 years) cancer diagnosis or relapse. Mothers (N = 318) provided self-reports and parent report of their children; children aged 10–17 years (N = 151) completed self-reports. Results Each sociodemographic variable demonstrated unique associations with mothers’ and children’s stress and distress in bivariate analyses. A cumulative sociodemographic risk measure was positively correlated with all stress and distress variables. In regression analyses predicting mothers’ and children’s distress, independent and cumulative sociodemographic measures were no longer significant when accounting for levels of stress. Conclusions Findings highlight the need to consider the ecological context of pediatric cancer, particularly the impact of sociodemographic disadvantage on stress and distress in this population.

Objective: College students face a significant number of stressors, increasing risk for internalizing and externalizing psychopathology. The current study examines two promising avenues of intervention aimed to reduce stress and prevent psychopathology in this population: a coping skills group and a cognitive training program. Participants: 62 undergraduate students from two universities were recruited from 2013 to 2015. Methods: Students were randomized to a 6-week coping skills group or cognitive training program and completed measures of stress, coping, executive function, and symptoms of anxiety, depression and Attention-Deficit Hyperactivity Disorder (ADHD) at pre- and post-intervention. Results: Participants in both conditions reported significant decreases in social stress, executive function difficulties, and anxiety symptoms post-intervention. Students in the cognitive program improved significantly more on measures of behavior regulation and ADHD symptoms compared to the coping group at post-intervention. Conclusions: Brief stress management interventions targeting coping and executive function may benefit college students at risk for psychopathology.

Objective To review research on observed family communication in families with children with chronic illnesses compared with families with healthy, typically developing children, and to integrate findings utilizing a unifying family communication framework. Method Topical review of studies that have directly observed family communication in pediatric populations and included a typically developing comparison group. Results Initial findings from 14 studies with diverse approaches to quantifying observed family communication suggest that families with children with chronic illnesses may demonstrate lower levels of warm and structured communication and higher levels of hostile/intrusive and withdrawn communication compared with families with healthy, typically developing children. Conclusion An integrative framework of family communication may be used in future studies that examine the occurrence, correlates, and mechanisms of family communication in pediatric populations.

The aims of this study were to (a) assess and compare sleep disturbances (including daytime and nighttime sleep patterns) in adolescents with depressive disorders and healthy peers, (b) examine the prevalence of pain in adolescents with depressive disorders and healthy peers, and (c) examine pubertal development, pain intensity, and depressive symptom severity as predictors of sleep disturbance. One hundred six adolescents (46 depressed, 60 healthy), 12 to 18 years (M = 15.10 years; 67% female; 77% Caucasian) completed subjective measures of sleep, presleep arousal, fatigue, and pain. Participants also underwent 10 days of actigraphic monitoring to assess nighttime and daytime sleep duration, sleep efficiency, and wake after sleep onset. Results indicated that youth with depression exhibited greater sleep disturbances on subjective and actigraphic sleep variables than healthy controls. Depressed youth also reported more frequent and severe pain than healthy youth. Linear regression analysis indicated that pain intensity and depressive symptoms predicted worse sleep quality across groups. The interaction term was also significant, such that adolescents with high levels of depressive symptoms had poor sleep quality when pain intensity levels were high. These results indicate that sleep is important to assess in youth with depression, and that pain may be an important target for sleep intervention in this population.

To examine parent–child communication (i.e., openness, problems) and child adjustment among youth with advanced or non-advanced cancer and comparison children. Families (n = 125) were recruited after a child’s diagnosis/relapse and stratified by advanced (n = 55) or non-advanced (n = 70) disease. Comparison children (n = 60) were recruited from local schools. Children (ages 10–17) reported on communication (Parent–Adolescent Communication Scale) with both parents, while mothers reported on child adjustment (Child Behavior Checklist) at enrollment (T1) and one year (T2). Openness/problems in communication did not differ across groups at T1, but problems with fathers were higher among children with non-advanced cancer versus comparisons at T2. Openness declined for all fathers, while changes in problems varied by group for both parents. T1 communication predicted later adjustment only for children with advanced cancer. Communication plays an important role, particularly for children with advanced cancer. Additional research with families affected by life-limiting conditions is needed.
