Analyses were conducted on a three level variable based on patient responses to the 4-item readiness scale; low = “never think about using less”, moderate = “sometimes think about using less”, and high = either “decided to use less” or “already trying to use less.” For the analysis of the interaction between empathy and readiness on 6-month TLFB outcomes among Other Drug MOTIV condition participants, medians were used for both the readiness and empathy variables because of distributional characteristics of these variables.
Categorical variables: N(%)
Continuous variables: Mean (SD)
Main Drug Other: Opioids, Cocaine, Sedatives
Homeless = one or more nights spent in a shelter or on the street in the past 3 months
SIP = short inventory of problems, score possible range 0-45
