The Youth Attitude Tracking Study (YATS) conducted in-depth interviews to understand the significant drop in military enlistment propensity among certain demographic groups. 120 interviews were conducted between December 1995 and June 1996 with balanced representation across race, propensity levels, and other factors. Interviews were semi-structured, audio recorded, and analyzed using grounded theory to identify themes in career decision-making and factors influencing propensity. The analysis provided insights into improving military advertising and addressing deterrents to enlistment.
