Abstract
Background: The Brief Addiction Monitor (BAM) is a simple tool for the periodic assessment of substance use disorders, but whether it can be applied in non-US settings is unknown. This study aimed to evaluate the reliability of a translated version of the BAM, named the BAM-Taiwan (BAM-T), and examine whether the baseline BAM-T score was associated with being lost to follow-up or with changes in the score at 3 months and 6 months, respectively.
Methods: A total of 2336 participants recruited from people who use drugs enrolled in treatment programs nationwide were followed up at 3 months and 6 months. Within this cohort, intraclass correlation reliability (ICCR) of interview responses was used to assess interrater reliability in 127 participants and test-retest reliability in 102 participants. To evaluate predictive validity, we examined associations between baseline BAM-T total score and follow-up outcomes, including loss to follow-up and subsequent BAM-T severity, using multivariable regression models. To account for informative loss to follow-up, stabilized inverse probability-weighted (IPW) linear regression models were applied.
Results: The BAM-T total score demonstrated excellent interrater (ICCR = 0.855) and 1-week test-retest reliability (ICCR = 0.789). Higher baseline BAM-T total score was associated with increased odds of loss to follow-up and with higher BAM-T total scores at both 3-month and 6-month follow-up. These associations remained robust in IPW-weighted analyses accounting for informative loss to follow-up. Each 1-SD increase in baseline BAM-T total score (7.9 points) was associated with a 5.21-point (robust SE = 0.18) higher BAM-T total score at 3 months (95% CI, 4.85-5.57; p < 0.0001) and a 4.95-point (robust SE = 0.21) higher score at 6 months (95% CI, 4.54-5.36; p < 0.0001) after adjustment for key sociodemographic and clinical covariates.
Conclusions: Our results provide empirical support for the utility of BAM-T as a simple tool for the measurement-based care of patients who use various types of drugs.
期刊介绍：
Substance Abuse Treatment, Prevention, and Policy is an open access, peer-reviewed journal that encompasses research concerning substance abuse, with a focus on policy issues. The journal aims to provide an environment for the exchange of ideas, new research, consensus papers, and critical reviews, to bridge the established fields that share a mutual goal of reducing the harms from substance use. These fields include: legislation pertaining to substance use; correctional supervision of people with substance use disorder; medical treatment and screening; mental health services; research; and evaluation of substance use disorder programs.
