ABSTRACT Anhedonia, a cardinal symptom of depression defined as difficulty experiencing pleasure, is also a possible endophenotype and prognostic factor for the development of depression. The onset of depression typically occurs during adolescence, a period in which social status and affiliation are especially salient. The medial prefrontal cortex (mPFC), a region implicated in reward, self-relevant processing, and social cognition, exhibits altered function in adults with anhedonia, but its association with adolescent anhedonia has yet to be investigated. We examined neural response to social reward in 27 late adolescents, 18-21years old, who varied in social anhedonia. Participants reported their social anhedonia, completed ratings of photos of unfamiliar peers, and underwent a functional magnetic resonance imaging task involving feedback about being liked. Adolescents with higher social anhedonia exhibited greater mPFC activation in response to mutual liking (i.e., being liked by someone they also liked) relative to received liking (i.e., being liked by someone whom they did not like). This association held after controlling for severity of current depressive symptoms, although depressive severity was also associated with greater mPFC response. Adolescents with higher levels of social anhedonia also had stronger positive connectivity between the nucleus accumbens and the mPFC during mutual versus received liking. These results, the first on the pathophysiology of adolescent anhedonia, support altered neural reward-circuit response to social reward in young people with social anhedonia.

    ABSTRACT: This paper presents retrospective and prospective data regarding time course parameters of major depressive disorder (MDD) in community adolescents (14 to 18 years old): time to onset and recovery and, among those who recovered, time to recurrence. Diagnostic interviews were conducted with 1,508 randomly selected high school students. Three hundred sixty-two had experienced at least one past or current episode of MDD. Mean age at onset of first episode was 14.9 (SD = 2.8). Early MDD onset was associated with female gender and suicidal ideation. MDD episode duration ranged from 2 to 520 weeks, with a mean of 26.4 weeks (SE = 3.3) and a median of 8.0 weeks. Longer episodes were observed in those whose depression occurred early (at or before age 15), whose depression had been accompanied by suicidal ideation, and for whom treatment was sought. Of the adolescents who recovered, 5% relapsed within 6 months, 12% within 1 year, and approximately 33% within 4 years. Shorter time to recurrence was associated with prior suicidal ideation and attempt and with later first onset. Risk of MDD is low in childhood, increasing substantially with adolescence. The majority of episodes in community adolescents are relatively brief, although the risk of recurrence is substantial. Suicidal behaviors are important mediators of episode duration and of recurrence.

    ABSTRACT: The authors' goal was to examine the relationship between subclinical depressive symptoms in adolescence and major depressive episodes in adulthood. An epidemiologic sample of 776 young people received psychiatric assessments in 1983, 1985, and 1992. Among adolescents not meeting criteria for major depression, the authors estimated the magnitude of the association between subclinical adolescent depressive symptoms and adult major depression. Symptoms of major depression in adolescence strongly predicted an adult episode of major depression: having depressive symptoms more than two-standard-deviations above the mean in number predicted a two-fold to three-fold greater risk for an adult major depressive episode. Symptoms of depression in adolescence strongly predict an episode of major depression in adulthood, even among adolescents without major depression.

    ABSTRACT: P. E. Meehl (1962) originally conjectured that hedonic capacity was an indicator of the latent class or taxon of schizotypy. However, P. E. Meehl (1989, 1990) subsequently diminished the role of hedonic capacity in his theory, indicating that hypohedonia is one of a dozen normal-range (nontaxonic) individual-differences factors that may potentiate the expression of schizophrenia. This dimensional-only view of hedonic capacity was tested by applying taxometric procedures to the Revised Social Anhedonia Scale (RSAS; M. L. Eckblad, L. J. Chapman, J. P. Chapman, & M. Mishlove, 1982) in a sample of college students (N = 1,526). Analyses indicated that the construct measured by the RSAS is taxonic in nature with a base rate approximating .10. These data are interpreted in the context of other findings suggesting that social anhedonia is an indicator of schizotypy.
