Higher numbers of subthreshold PTSD symptoms were associated with greater impairment, comorbidity, and suicidal ideation. Disability and impairment found in previous studies of subthreshold PTSD symptoms may be related in part to the presence of comorbid disorders. However, the presence of subthreshold PTSD symptoms significantly raised the risk for suicidal ideation even after the authors controlled for major depressive disorder. Given the broad public health implications of these findings, more efforts are needed to identify subthreshold PTSD symptoms in clinical populations, epidemiologic surveys, and treatment studies.

Objective. Offspring of parents with major depressive disorder (MDD) face three-fold higher risk for MDD than offspring without a family history. Although MDD is a major cause of morbidity and mortality, neural correlates of risk for MDD remain poorly understood. This study compares amygdala and nucleus accumbens activation in children and adolescents at high and low risk for MDD under varying attentional and emotional conditions. Methods. Thirty-nine juveniles, 17 offspring of parents with MDD (high-risk group) and 22 offspring of parents without histories of MDD, anxiety or psychotic disorders (low-risk group) completed a functional magnetic resonance imaging study. During imaging, subjects viewed faces that varied in intensity of emotional expressions across blocks of trials; while attention was unconstrained (passive viewing), and constrained (rate nose width on face; rate subjective fear while viewing face). Results. When attention was unconstrained, high-risk, relative to lowrisk, subjects showed greater amygdala and nucleus accumbens (NAcc)

Social anxiety is associated with a distinct pattern of treatment barriers. Treatment access may be improved by building public awareness of locally available services, easing the psychological and financial burden of entering treatment, and increasing health care professionals' awareness of its clinical significance.

Social anxiety disorder, whose onset peaks in adolescence, is associated with significant impairment. Despite the availability of effective treatments, few affected youth receive services. Transporting interventions into schools may circumvent barriers to treatment. The efficacy of a school-based intervention for social anxiety disorder was examined in a randomized wait-list control trial of 35 adolescents (26 females). Independent evaluators, blind to treatment condition, evaluated participants at preintervention, postintervention, and 9 months later. Adolescents in the intervention group demonstrated significantly greater reductions than controls in social anxiety and avoidance, as well as significantly improved overall functioning. In addition, 67% of treated subjects, compared to 6% of wait-list participants, no longer met criteria for social phobia following treatment. Findings support the possible efficacy of school-based intervention for facilitating access to treatment for socially anxious adolescents.

Although caution is needed in generalizing the results beyond members of patient advocate groups, the key patterns found here were also found in previous analyses of general population surveys carried out in the US and Canada. The critical and consistent finding in all these studies is that presumably curable adolescents with early-onset disorders are, in effect, ignored by the treatment system in these countries. Aggressive outreach and intervention among early-onset cases might prove to be a cost-effective approach both to prevent the onset of secondary disorders and to improve success in treating primary disorders.
