Sex differences in the expression of depression: A developmental interaction effect

A 1982 study by Kleinke and colleagues indicated sex differences among college students in the expression of depression on the Depression Coping Questionnaire and Beck's Depression Inventory, with females showing a significantly greater tendency to label their feelings and symptomatology. Using the Structured Pediatric Psychosocial Interview (SPPI), we have examined 1015 public-school pupils ranging from 5 through 19 years of age. On the SPPI's depression-related scales of Unhappiness and Resentfulness, developmental age level appears to interact significantly with respondent's gender in determining the extensity of content expressed. Our results with older adolescents replicate the sex differences reported by Kleinke et al. (Sex Roles, 1982, 8, 877–889), but at earlier age levels such differences may not be salient. Therefore, the inclusion of a developmental parameter would appear especially important to the investigation of processes by which sex differences in the expression of affectivity become manifest by late adolescence.We wish to thank Mr. Gayle Seymour of the University of Akron Computer Center for his technical programming which culminated in graphics displayed in the present study.
