Abstract

Background

This study examines whether readiness to change is a predictor of substance use outcomes and explores factors associated with RTC substance use among patients at South African emergency departments.

Methods

We use data from participants enrolled into a randomized controlled trial of a brief substance use intervention conducted in three emergency departments in Cape Town, South Africa.

Results

In adjusted analyses, the SOCRATES “Recognition” (B = 11.6; 95 % CI = 6.2–17.0) and “Taking Steps” score (B = -9.5; 95 % CI = -15.5- -3.5) as well as alcohol problems (B = 4.4; 95 % CI = 0.9–7.9) predicted change in substance use involvement at 3 month follow-up. Severity of depression (B = 0.2; 95 % CI = 0.1–0.3), methamphetamine use (B = 3.4; 95 % CI = 0.5- 6.3) and substance-related injury (B = 1.9; 95 % CI = 0.6–3.2) were associated with greater recognition of the need for change. Depression (B = 0.1; 95 % CI = 0.04 -0.1) and methamphetamine use (B = 2.3; 95 % CI = 0.1 -4.2) were also associated with more ambivalence about whether to change. Participants who presented with an injury that was preceded by substance use were less likely to be taking steps to reduce their substance use compared to individuals who did not (B = -1.7; 95 % CI = -5.0- -0.6).

Conclusion

Findings suggest that brief interventions for this population should include a strong focus on building readiness to change substance use through motivational enhancement strategies. Findings also suggest that providing additional support to individuals with depression may enhance intervention outcomes.
