Social anhedonia, a tendency toward experiencing social stimuli as less positive or pleasurable, is associated with maladaptive personality traits, poor interpersonal functioning, and psychopathology, and is typically elevated in males compared with females. However, the correlates of social anhedonia in youth have not been well defined. In this study, 275 young adolescents from a community sample completed measures of social anhedonia, personality, interpersonal functioning, and symptoms; mothers also completed personality and symptom measures. Social anhedonia was associated with low positive emotionality and, to a lesser extent, high disinhibition and negative emotionality. Social anhedonia was also correlated with several markers of poor interpersonal functioning and a wide range of internalizing and externalizing symptoms. Interactions between sex variables indicated that associations were particularly strong in males. Overall, findings suggest that social anhedonia is an important construct to explore in early adolescence, with meaningful associations with psychosocial functioning, especially among males.
