The primary focus of this study emphasized a family-centered home based addiction treatment approach which resulted in diverse outcomes than traditional addiction treatment. A secondary focus involved quality of life (QOL) using the Multidimensional Life Quality (MILQ) instrument, which examined QOL for clients and key family members. QOL results were inconclusive in this study. Client engagement in the treatment process was measured using a checklist adapted from DiClemente‘s (2003) and Connors, Donovan, and DiClemente‘s (2001) work on stages of change in addiction treatment. Eighty-two case records were examined for individuals that participated in a family-centered home based approach, referred to as Rehab at Home (RAH) while simultaneously participating in single or various combinations of traditional treatment modalities as well as individuals who exclusively participated in single or a combination of traditional treatment modalities. The predictors of engagement that emerged from the study included (a) RAH, (b) family involvement, (c) treatment intensity, (d) gender, (e) use of marijuana, and (f) past alcohol and other drug treatment. The odds of engagement for clients in RAH were 6.30 times greater when compared to traditional treatment only. Results showed that females who reported using drugs other than marijuana with no previous treatment episodes had the highest probability of engagement in the treatment process. Marijuana users, regardless of gender, had the lowest probability of engagement. A converse relationship between treatment intensity and engagement was also noted, signifying that shorter bursts of treatment over a longer period of time led to a higher probability of engagement. This study supports that RAH was significantly responsible for client engagement and provides empirical support for implementing interventions based on the chronic care model.
