Kaiser-Meyer-Olkin measure of sampling adequacy being .77, above the recommended value of .60 (Kaiser, 1974), and Bartlett's test of sphericity ((χ2 = 12221.9, p < .001) was also significant indicating appropriate values to carry out subsequent factor analysis. After analysis the items reduced to 40 and 10 sub domains were identified. The newly established scale was validated with aggression and coping skills as research indicates father's involvement has negative correlation with adolescent's aggression and has positive correlation with adolescent's coping skills. Therefore, a negative association between newly developed S&Q FI Inventory and adolescent's aggression level is indicative of its discriminate validity. Whereas S&Q FI Inventory has positive correlation with adolescent's coping skills suggesting its convergent validation. This scale helps in measuring father's involvement in adolescents and helps the researchers and mental health professionals for the advancement of research work and making strategies for issue due to father's noninvolvement in Pakistan.
