Sex and Age Differences in Problems and Interests of Adolescents.
The problems and interests of 1,366 adolescents were investigated using an instrument devised by Symonds and later used by Harris and Kaczkowski. Findings of the various studies were compared to determine the val idity of Symonds' hypothesis that changes in the social and economic structure of society would immediately change the relative emphasis of these problems and interests. Certain problems and interests offered by the instrument did alter their position in the 32 years spanned by the four studies, but others seemed to be imper vious to the influence of the changes of which Symonds spoke. The influence of regional and geographic differ ences in the samples used in the various studies is not known.
