Overdose Prevention Intervention Package (OPIP)
WJCOIN-II's multi-level 2 X 2 randomized factorial design will examine the effectiveness of OPIP components across four study conditions randomly assigned after baseline data collection (n=75 per condition, 100 per jail site), summarized in Table 7 and described below. In addition to group assignment, outcomes will be assessed as a function of engagement in each intervention component defined as the number of sessions attended (RC and CM conditions) and perceived support, which is a count of the number of types of support provided by the RC and SP (e.g., emotional, financial, etc.).
