Sleep problems and their relation to cognitive factors, anxiety, and depressive symptoms in children and adolescents

Background: Existing research indicates sleep problems to be prevalent in youth with internalizing disorders. However, childhood sleep problems are common in the general population and few data are available examining unique relationships between sleep, specific types of anxiety and depressive symptoms among non‐clinical samples of children and adolescents. Methods: The presence of sleep problems was examined among a community sample of children and adolescents (N=175) in association with anxiety and depressive symptoms, age, and gender. Based on emerging findings from the adult literature we also examined associations between cognitive biases and sleep problems. Results: Overall findings revealed significant associations between sleep problems and both anxiety and depressive symptoms, though results varied by age. Depressive symptoms showed a greater association with sleep problems among adolescents, while anxiety symptoms were generally associated with sleep problems in all youth. Cognitive factors (cognitive errors and control beliefs) linked with anxiety and depression also were associated with sleep problems among adolescents, though these correlations were no longer significant after controlling for internalizing symptoms. Conclusions: Results are discussed in terms of their implications for research and treatment of sleep and internalizing disorders in youth. Depression and Anxiety, 2009.

Cognition in childhood anxiety: conceptual, methodological, and developmental issues

Anxiety disorders are one of the most common psychiatric disorders in the general child population and can have significant impact on immediate and long-term functioning. Despite the common use of cognitive-behavioral interventions that target specific, negative thoughts in anxious children, it is unclear that the extant literature clearly documents cognitive aberrations among these children. In this review, conceptual and methodological issues related to the assessment of cognition in anxious children are highlighted and empirical data addressing these areas are evaluated. Furthermore, data addressing cognitive change as a function of treatment outcome is examined, and the impact of cognitive development as a moderating variable is discussed. Finally, areas for future research are presented.

Social Skills and Social Phobia: An Investigation of DSM-IV Subtypes

Social phobia is characterized as pervasive social timidity in social settings. Although much is known about this disorder, aspects of its clinical presentation remain unexplored, in particular characteristics that distinguish the generalized and non-generalized subtypes. For example, it remains unclear whether patients with the non-generalized subtype display social skills deficits in social interactions, and if so, are these deficits clinically, as well as statistically, significant? In this study, adults with either the non-generalized (NGSP; n=60) or generalized (GSP; n=119) subtype of social phobia and adults with no psychological disorder (n=200) completed an extensive behavioral assessment of social skill and social anxiety. As expected, adults with NGSP and GSP reported equal distress and displayed similar rates of avoidance during an Impromptu Speech Task when compared to adults with no disorder. In contrast, the three groups were distinctly different when interacting with another person in various social situations. Adults with NGSP displayed social skill deficits when compared to individuals with no disorder, but they had fewer deficits than the GSP subtype. However, the identified skill deficits were clinically as well as statistically significant only for the GSP subtype. The results are discussed in terms of the contribution of skill deficits to the conceptualization and treatment of social phobia.

Sleep fears, sleep disturbance, and PTSD symptoms in minority youth exposed to Hurricane Katrina

Posttraumatic stress disorder (PTSD) is common following the experience of a natural disaster and sleep disturbance is an important influence on its course in adults, but little research is available examining sleep and PTSD in youths. This studys objective was to evaluate the role of sleep disturbance and the developmentally influenced factor of fear of sleeping alone in the maintenance of posttraumatic stress (PTS) symptoms in youths. Deidentified data of 191 Hurricane Katrina survivors ages 8 to 15 were used in this study. We found cross-sectional relationships of sleep disturbance and fear of sleeping alone with PTS symptom severity. Longitudinal analysis also indicated that general sleep disturbance at 24 months (T1) was predictive of PTS symptoms severity at 30 months (T2) even after adjusting for PTS symptom severity at T1, age, sex, and continued disrepair to the home. These results have implications for intervention strategies among youth exposed to traumatic events.

Mediators and Moderators of Outcome in the Behavioral Treatment of Childhood Social Phobia

OBJECTIVE The current study examined mediators and moderators of treatment response among children and adolescents (ages 7-17 years) with a primary diagnosis of social phobia. METHOD Participants were 88 youths participating in one of two randomized controlled treatment trials of Social Effectiveness Therapy for Children. Potential mediators included changes in observer-rated social skill and child-reported loneliness after 12 weeks of Social Effectiveness Therapy for Children. Age and depressive symptoms were examined as potential moderators. RESULTS Loneliness scores and social effectiveness during a role-play task predicted changes in social anxiety and overall functioning at posttreatment. Changes in social anxiety were mediated by child-reported loneliness. Outcomes were not moderated by age or depressive symptoms. CONCLUSIONS Findings support the role of loneliness as an important mechanism of change during treatment for childhood social phobia.

Are Clinicians' Assessments of Improvements in Children's Functioning “Global”?

In this study, the authors examined the relations among clinician ratings of treatment improvement and discrepancies between parent and blinded laboratory rater reports of child social functioning administered before and after treatment for social anxiety disorder. Participants included a clinic sample of 101 children (7–16 years old; M = 11.67, SD = 2.57; 51 girls, 81% Caucasian) receiving treatment as part of a two-site controlled trial. Overall, clinician ratings reflected lack of improvement when parents reported persistent (i.e., pre- to posttreament) social functioning deficits not reported by blinded raters. However, when blinded raters reported persistent social skill deficits not reported by parents, we did not observe the same effect on clinician ratings as we did when the direction of discrepant reports was reversed. We replicated these observations in a subset of participants (n = 81) providing parent and child pre–post reports of social anxiety symptoms. These findings have implications for the interpretations of clinical ratings as “primary outcome measures” within controlled trials.

Somatic Symptoms and Anxiety Among African American Adolescents

Somatic symptoms are an associated feature of anxiety disorders that have received little research attention among non-White samples. In addition, the majority of previous studies have examined the influence of somatic symptoms in a cross-sectional rather than a prospective manner. This study examines the prevalence of 12 somatic symptoms, the association of somatic and anxiety symptoms (both concurrently and prospectively) with psychosocial functioning, and gender differences in somatic symptoms among a community sample of 114 African American adolescents (57 girls). In all, 83% of the sample reported at least one somatic symptom (some or most of the time within the past 2 weeks), and on average, adolescents reported 2.5 somatic symptoms. Somatic symptoms correlated positively with severity of anxiety symptoms and negatively with aspects of perceived competence. After the initial level of anxiety symptoms was controlled for, somatic symptoms were a unique predictor of perceived competence (at initial assessment) and anxiety symptoms (at 6-month follow-up). Overall, girls endorsed significantly more somatic symptoms than did boys. Findings replicate those of studies with White samples and suggest that somatic symptoms may be a risk factor for anxiety disorders among African American youth.

Social anxiety in adolescents and young adults : translating developmental science into practice

The contributors to this book examine social anxiety in the lives of young people (aged 12 to 25) in the context of dating and romantic relationships, alcohol and drug use, performance anxiety and school refusal, and alongside comorbid disorders such as depression. The unique challenges faced by special populations including LGBT, ethnic minority, and autistic adolescents are also considered, while clinically-oriented authors describe the latest techniques in assessment and treatment, including pharmacotherapy and cognitive behavioral approaches. The final chapter presents a model for SAD treatment in schools, with an eye towards the development of future programs for large-scale intervention. Compassionate in tone and comprehensive in scope, Social Anxiety in Adolescents and Young Adults represents a significant step forward in the field of social anxiety.

Objective sleep patterns and severity of symptoms in pediatric obsessive compulsive disorder: a pilot investigation.

Sleep disturbances are common among youth with anxiety disorders, yet objective assessments of sleep in children with obsessive compulsive disorder (OCD) have been the focus of scant research. We therefore compared a small group of non-medicated, non-depressed children with primary OCD (ages 7-11 years) to matched healthy controls using home-based actigraphy during a 7-day prospective assessment. Validated parent and child sleep measures also were collected, and associations among objective sleep variables and severity of obsessions and compulsions were examined. We found significantly fragmented sleep patterns in the OCD group compared to controls including reduced total sleep time (TST) and longer wake periods after sleep onset. Severity of compulsions showed a significant negative correlation with TST. These preliminary findings indicate the presence of sleep abnormalities in pre-pubescent OCD patients with potential implications for future examinations of early developmental processes and features of the disorder.

Negative Self-Imagery Among Adolescents with Social Phobia: A Test of an Adult Model of the Disorder

Based on findings from the adult literature, this study examined the role of negative self-images (NSI) in social phobia during adolescence. NSI was manipulated among 21 nonphobic (IMAG) adolescents (M age = 14.05 years, SD = 1.56) during two social tasks. Self and observer-rated anxiety and performance as well as co-occurring cognition were compared to 21 adolescents with social phobia (SOC) and 21 control adolescents not instructed to use self-imagery. Few differences in observer-rated anxiety or performance were found between the IMAG and control groups, whereas SOC adolescents were consistently rated as more anxious and poorer social performers. Nonsignificantly higher rates of anxiety were reported by the IMAG group compared to controls, but anxiety was not associated with decrements in performance or social skill. A significantly fewer number of on-task thoughts reported by IMAG adolescents suggests that inability to attend to the interaction itself, rather the presence of NSI, served to increase anxiety.
