Introduction:

Faith-based centers are major providers of residential treatment for substance use problems in Mexico, but relatively few studies have been conducted in this context.

Objective:

To explore factors associated with treatment retention in two faith-based (with different religious orientation) residential treatment facilities for male drug users in Tijuana, Mexico.

Method:

We conducted an exploratory follow-up study of 328 clients admitted during 2014-2015 to either an Evangelical Pentecostal center or a faith-based center without a specific religious affiliation. The main outcome was retention, defined as remaining in treatment for at least three months.

Results:

Among participants, the retention rate was 38.7%. Multivariate logistic regression models showed that age (OR 1.04; 95% CI [1.01, 1.06]; p = .002) and having used heroin or opioids in the past 30 days (OR .50; 95% CI [.25, 1.00]; p = .049) were associated with retention. Having a personal religious affiliation was associated with retention in the Evangelical Pentecostal center, but not in the center without a specific religious affiliation.

Discussion and conclusion:

The retention rate was low, but within the previously reported range. The interaction of personal religious affiliation and the religious orientation of the center suggests that a match between a person’s religious convictions and those of the center could be important for retention. More research is needed to clarify the utility of faith-based centers for religious and non-religious drug users.
