ABSTRACT Studies of adult bipolar patients and adolescents with major depression indicate that life stress and mood symptoms are temporally and causally related to one another. This study examined whether levels of life stress predict levels of mood symptoms among bipolar adolescents participating in a treatment development study of family-focused psychoeducation and pharmacotherapy.
Bipolar adolescents (n=38) who reported a period of acute mood symptoms within the prior 3 months were recruited for a 1-year study of life stress. Clinician-administered evaluations were completed with adolescents and parents at 3-month intervals for up to 12 months, using the UCLA Life Stress Interview and the K-SADS Mania and Depression Rating Scales.
Chronic stress in family, romantic and peer relationships was associated with less improvement in mood symptoms over the study year. The frequency of severe, independent life events also predicted less improvement in mood symptoms. Higher levels of chronic stress in family and romantic relationships, and higher severity of independent events, were more strongly associated with mood symptoms among older adolescents. Results were independent of adolescents' psychosocial treatment regimens.
The majority of adolescents received family-focused psychoeducational treatment and all were being treated with psychotropic medication. The influence of life stress on mood symptoms may have been attenuated by intensive intervention.
Stress is linked to changes in mood symptoms among bipolar adolescents, although correlations between life events and symptoms vary with age. Chronic stress in family, romantic, and peer relationships are important targets for psychosocial intervention.

    ABSTRACT: Objective Longitudinal studies have begun to clarify the phenotypic characteristics of adolescents and young adults at clinical high risk for psychosis. This 8-site randomized trial examined whether a 6-month program of family psychoeducation was effective in reducing the severity of attenuated positive and negative psychotic symptoms and enhancing functioning among individuals at high risk. Method Adolescents and young adults (mean 17.4+4.1 years) with attenuated positive psychotic symptoms, brief and intermittent psychosis, or genetic risk with functional deterioration were randomly assigned to 18 sessions of family-focused therapy for individuals at clinical high risk (FFT-CHR) in 6 months or 3 sessions of family psychoeducation (enhanced care, or EC). FFT-CHR included psychoeducation about early signs of psychosis, stress management, communication training, and problem-solving skills training, whereas EC focused on symptom prevention. Independent evaluators assessed participants at baseline and 6 months on positive and negative symptoms and social-role functioning. Results Of 129 participants, 102 (79.1%) were followed at 6 months. Participants in FFT-CHR showed greater improvements in attenuated positive symptoms over 6 months than participants in EC (F[1,97]=5.49, P=.02). Negative symptoms improved independently of psychosocial treatments. Changes in psychosocial functioning depended on age: participants over 19 years showed more role improvement in FFT-CHR, whereas participants between 16 and 19 years showed more role improvement in EC. The results were independent of concurrent pharmacotherapy. Conclusion Interventions that focus on improving family relationships may have prophylactic efficacy in individuals at high risk for psychosis. Future studies should examine the specificity of effects of family intervention compared to individual therapy of the same duration and frequency.

    ABSTRACT: Major psychiatric disorders such as schizophrenia, major depressive and bipolar disorders are severe, chronic and debilitating, and are associated with high disease burden and healthcare costs. Currently, diagnoses of these disorders rely on interview-based assessments of subjective self-reported symptoms. Early diagnosis is difficult, misdiagnosis is a frequent occurrence and there are no objective tests that aid in the prediction of individual responses to treatment. Consequently, validated biomarkers are urgently needed to help address these unmet clinical needs. Historically, psychiatric disorders are viewed as brain disorders and consequently only a few researchers have as yet evaluated systemic changes in psychiatric patients. However, promising research has begun to challenge this concept and there is an increasing awareness that disease-related changes can be traced in the peripheral system which may even be involved in the precipitation of disease onset and course. Converging evidence from molecular profiling analysis of blood serum/plasma have revealed robust molecular changes in psychiatric patients, suggesting that these disorders may be detectable in other systems of the body such as the circulating blood. In this review, we discuss the current clinical needs in psychiatry, highlight the importance of biomarkers in the field, and review a representative selection of biomarker studies to highlight opportunities for the implementation of personalized medicine approaches in the field of psychiatry. It is anticipated that the implementation of validated biomarker tests will not only improve the diagnosis and more effective treatment of psychiatric patients, but also improve prognosis and disease outcome.

    ABSTRACT: [Clin Psychol Sci Prac 18: 342–356, 2011] This article reviews studies of interpersonal functioning, social cognition, and life stress in children and adolescents with bipolar disorder (BD). Peer and family relationships of youth with BD are impaired in comparison to healthy controls and youth with attention‐deficit hyperactivity disorder (ADHD). Social‐cognitive deficits, such as impaired facial affect recognition, may underlie these interpersonal difficulties. Affect among youth with BD is particularly dysregulated in interpersonal situations and is often characterized by elevated anger and frustration. Preliminary evidence suggests that life stress is associated with course. Further research in this area must consider the role of comorbidity and family environment in determining psychosocial outcomes. Studies should aim to incorporate naturalistic and developmentally appropriate measures of social functioning and examine the impact of psychosocial interventions in modifying social dysfunction.
