Physical and social anhedonia in female adolescents: A factor analysis of self-report measures.

Anhedonia is a transdiagnostic symptom of psychopathology that includes diminished positive emotions and anticipation and enjoyment of reward, with particular salience during adolescence. However, the construct validity of anhedonia dimensions is not well established, thus limiting operationalization and generalization of the construct. We applied exploratory and confirmatory factor analyses to identify latent dimensions of anhedonia across four commonly used self-report measures covering different facets of anhedonic experience within a nonclinical sample of female adolescents across two waves of data collection (N = 173, Mage = 19.25; N = 147, Mage = 20.23). Factor analyses yielded a two-factor model with a physical anhedonia factor emphasizing enjoyment from physical sensations and a social anhedonia factor focusing on emotional connections with other people. These results have implications for the measurement of anhedonia in women's emotional well-being and mental health research, including research designed to identify facets of anhedonia that predict the onset, severity, and persistence of psychopathology.
