Research tools were Frost, Marten, Lahart & Rosenblate’s (1990) Multiple Perfectionism Scale, Ryff’s (1989) Psychological Well-Being Scale and Spanier’s (1976) Dyadic Adjustment Scale. The data for 405 participants after exclusion of 90 distorted questionnaires and removal of five outliers from the research process, was analyzed by structural equation modeling. Results: Results showed that psychological well-being mediates the relationship between personal standards (β= 0.229, P= 0.001), organization (β= 0.064, P= 0.047), concern over mistakes (β= -0.212, P= 0.001), doubts about actions (β= -0.212, P= 0.001), parental criticism (β= -0.257, P= 0.001), parental expectations (β=0.141, P=0.001) with marital adjustment.
