Abstract
The purpose of the present research was to develop an easily administered measure of intimacy that could apply to several types of relationships in adolescents and adults. In a set of four survey studies, the sixty-item Psychosocial Intimacy Questionnaire (PIQ) was found to have high internal consistency (alpha = 0.97) and good test-retest stability over a three-week interval, r = 0.84. Correlations with other measures provided evidence for convergent and discriminant validity of the PIQ. Factor analysis indicated that psychosocial intimacy may be a function of romantic love, supportiveness and communication ease. Intimacy level of heterosexual relationships in young adults appears to be more affected by partners' feminine qualities than by sex-typing or androgyny.
