This study gathered data using the Important Persons and Activities instrument to record changes in popular activities over a 2-year study of 270 justice-involved individuals randomized into three aftercare conditions: self-run Oxford Houses, a staffed therapeutic community (TC), or usual aftercare (UA). Participants listed important activities during the 2-year study at baseline and at four subsequent 6-month intervals. Categorization of these activities and a descriptive analysis were conducted for Wave 1 (baseline), at Wave 3 (Year 1), and Wave 5 (Year 2). Standardized scores were computed to test differences in proportions of the #1 most favored activity across conditions. Descriptive results also demonstrated that Reading/Writing activities, and Exercise/Sports activities, were most reported at baseline. By Wave 5, Education/Work and Interacting with Others were the most reported activities. These findings indicated that solitary activities, such as Reading/Writing, may play a predominant role in early aftercare whereas Work/Education and social activities increase later on. Implications for future research of changing activities during recovery trajectories are discussed.
