title: A comparison of psychometric and convergent validity for social anhedonia and social closeness.
abstract: Social anhedonia is an important construct that describes individual differences in preferences for interacting in and experiencing pleasure from social interactions and has been a central construct in the schizotypy literature. The description of social anhedonia is very similar to that of social closeness from the personality literature. However, no published studies have directly compared associations between social anhedonia and social closeness with an array of other measures of anhedonia, personality, and depression. The present study examined the internal psychometrics of primary measures of social anhedonia and social closeness; the bivariate association between social anhedonia and social closeness; and the associations between these target constructs and measures of individual differences in a large sample of undergraduate students (mean age = 20.53 years; 76.3% were women). We found that (a) social anhedonia and social closeness were strongly correlated; (b) the unidimensional measurement model for social closeness was stronger than that for social anhedonia; (c) the pattern of associations for social closeness and social anhedonia with measures of physical anhedonia, personality, and depressive symptoms were substantively identical; and (d) a collection of items from both measures assessed information across a wider range of social anhedonia than either instrument alone. Thus, given the similar patterns of validity against multiple criteria social anhedonia and social closeness appear to be representing very similar constructs. The Social Closeness scale provides complementary information to the social anhedonia dimension. Our results provide recommendations for instrument selection when normative or elevated levels of social anhedonia are intended to be assessed. (PsycINFO Database Record
