This investigation was directed at establishing personal, environmental and psychological correlates of scholastic performance among the medical students of West Visayas State University College of Medicine. It also attempted to ascertain correlations among the various variables. This descrptive-correlational research utilized four sets instruments: the Rosenberg Self-Esteem Scale, Type A Type B Behavior Quiz, the abridged Rotter Internal-External Control Scale and the Aggressiveness Scale. The instruments were administered among 55 medical seniors chosen at random. Means and standard deviations, the t-test, analysis of variance, Pearson r and Stepwise Multiple Regression Analysis were employed as statistical tools. The .05 alpha level was used for inferential tests. Study results showed that the senior medical students of the WVSU College of Medicine had low scholastic performance, low self-esteem, high internal locus of control, Type A behavior, and were assertive. Significant differences existed in the medical students' scholastic performance when grouped as to sex (in favor of the males), NMAT percentile rank(in favor of the high NMAT performers), baccalaureate course ( in favor of the non-Biological Science degree holders), GPA in baccalaureate course (in favor of the high GPA group), and annual family income (in favor of the high income group). The students residing in the rural areas reflected significantly lower self-esteem than the students residing in urban areas. The males manifested A- behavior type while the females reflected A behavior type. NMAT percentile rank came out to be the most powerful predictor of medical scholastic performance followed by baccalaureate course and behavior type. No significant differences were observed in locus of control and assertiveness among the students classified as an entire group or according to certain categories. Finally, no significant relationships were found to exist among scholastic performance, self-esteem, locus of control, behavior types and assertiveness.
