The influence of the sex, grade, religiosity and birth order of adolescents on adolescents perceptions of the parental power structure in the family was examined in this study. Parental Power was conceptualized as a multidimensional variable following the French and Raven (1959) formulation of social power bases. The parental power dimensions measured were perceived outcome-control, referent, legitimate and expert power. A modified version of Smith's parental power instrument was given to subsamples taken from a larger pool of high-school and college adolescent respondents, yielding 458 questionnaires (231 females, 227 males). Multiple regression was utilized to examine the relative influence of these adolescent variables on the differing parental power dimensions for each parent. Adolescents' sex and religiosity were found to be the most important determinant variables. Female adolescents consistently perceived the mother as having more power than did male adolescents, with both sexes viewing power of the father similarly. Consequently, females saw the parental power structure as more equalitarian than did males. Religiosity, used as an indicator of traditionalism, was consistently found to be positively associated with parental power perceptions for both sexes, with the exception of parents' outcome-control power.
