The study investigated the relationship of anomie and dogmatism to asociality or predelinquency in eleventh-grade Catholic boys. The population consisted of 536 Mexican American, Negro, and Anglo boys in 6 parochial high schools. Instruments used were a student questionnaire, the Jesness Inventory, the Lowe Anomie Scale, and the Rokeach Dogmatism Scale-Form E. Observed asociality was evaluated in terms of underachievement, absenteeism, dean referrals, and deportment ratings. Group differences were investigated on some of the foregoing variables and on personal-social variables such as socioeconomic status, physical size, school program, social participation, expressed interests and hobbies, and school attitudes. Multiple stepwise regression and analysis of variance were the statistical procedures used. A significant positive relationship was found between observed asocial behavior and tested predelinquency, anomie, and dogmatism. Dogmatism related positively with observed asocial behavior for Anglo but not for Black or Mexican Americans. Black Americans had the highest ratings on observed asocial behavior, tested predelinquency, dean referrals, and negative deportment. Mexican Americans had the lowest ratings on tested predelinquency and dean referrals. Anglo Americans had the lowest ratings on anomie and deportment ratings. No significant differences emerged between the groups in terms of dogmatism, underachievement, and absenteeism. (JH)
