The social history of 2,200 Army basic trainees was examined to determine the importance of pre-selected social factors and perceived problem areas of basic trainees in predicting their completion of basic combat training. Data regarding forty-six variables collected via the Fort Knox Community Mental Health Activity (CMHA) Social History form were analyzed for four groups of trainees: (1) the control group, who completed their training and were never referred to the CMHA staff for evaluation; (2) the counseling-adjust group, who were referred to the CMHA staff for evaluation, received counseling, and completed training; (3) the fail-to-adjust group, who were evaluated by the CMHA staff as experiencing difficulties not amenable to treatment and eventually were discharged; and (4) the recommend-for-discharge group, who were evaluated by the CMHA staff and recommended for discharge. It was concluded that (1) pre-selected social factors and perceived problem areas are influences on whether or not an individual completes basic training; (2) those individuals who perceive themselves as not having problems, as measured by the CMHA Social History, have a greater probability of completing basic combat training than those who perceive themselves as having problems; and (3) age and educational level are not predictors of successful completion of basic combat training.
