This study investigated the effects of three methods of teaching interpersonal relationship skills with the film "Relationships with Other People." The three methods of instruction were presentation of film only, print-based material, and formal classroom instruction. The following pre- and posttest instruments were administered to 210 California students randomly selected from three regional occupational programs: the Sociability, Achievement via Independence, and Tolerance scales of the California Psychological Inventory and a semantic differential test and criterion referenced test, both constructed by the experimenter. The data collected were statistically analyzed according to the fourteen hypotheses concerning the effects of the treatment. The major findings were these: The film produced both affective and cognitive growth in interpersonal relationship skills in most students, especially the high achievement via independent students; the amount of growth was directly related to the amount of additional instructional material used; and low tolerance students may need alternate, presently undetermined methods of instruction in interpersonal relationship skills in order to show significant affective gains. The appendixes include the film script, the print-based materials, copies of the pre- and posttest instruments, and the raw data. (Author/BM)
