Participation in Substance Abuse Clinical Trials: Comparing Gender, Racial/Ethnic and Age Groups Carmen Rosa NIH/NIDA Background REM/Women historically underrepresented in clinical trials
Much literature regarding recruitment, less on retention Greater vulnerability of these populations to adverse medical/social consequences of SUD Need to successfully retain in research studies Background (cont) Reported that REM have lower retention than NHW (both in treatment and research) Others have not seen differences in some SUD studies Similar reports regarding age and gender Most analyze retention based on study completion or attendance to F/ U sessions
Methods Analyzed 24 RCTs completed in the CTN CTN established several strategies for RR 9 Rx/combination and 15 psychosocial trials ~11,449 subjects across 190 CTP Retention was measured using 3 criteria: Availability of primary outcome Results: Demographic Characteristics Count Percent Male
74.0 73.3 70.5 Female Male to to to to to <25 <35 <45 <55 <65
Overall* Discussion No statistically significant differences among gender or race/ethnic groups Difference for some indicators in some of the trials, showing that NHW and Hispanics remain in certain studies longer than NHAA Differences among age groups: retention was higher for older participants Recommendations Include more AIAN and AAPI participants in clinical trials CTN researching barriers to TX and expanding to include treatment
programs CBPR with AIAN populations Increase efforts in retention of younger and NHAA participants Investigate reasons for lower retention in younger populations Limitations Observational analysis Several factors may affect retention Primary drug use/patterns of drug use Trial specific definition of retention indicators Did not analyze data for specific reasons for attrition Racial/Ethnic Differences in the Rates and Correlates of

greater use of protection Whites were most likely to be IDUs Hispanics least likely to be IDUs but engaged in more high risk HIV drug risk behaviors Conclusions Relationship between certain HIV risk factors and HIV risk behaviors differed between ethnic groups: Alcohol use and psychiatric severity was related to engaging in higher sex risk behaviors for African-Americans Psychiatric severity was related to engaging in higher sex risk behaviors for Whites Drug use severity was associated with engaging in higher risk drug behaviors for Hispanics, and to a lesser degree,
Conclusions The findings from the present study suggest that there is a context (or culture) in which HIV high risk behaviors occur within racial/ethnic groups as well as differences in the presence of risk factors associated with engaging in HIV risk behaviors. This is consistent with calls to culturally adapt evidence based interventions.

Persons Dimension (Bernal & SaezSantiago, 2006): Consider the role of the existing client-therapist racial/ethnic similarity/dissimilarity Gaps in the Literature (1) Few Racial and Ethnic Matching (REM) studies have examined the relation of REM to engagement, retention, and treatment outcomes of substance using youth. (2) Lack of analysis for specific
racial/ethnic minority groups. (3) No study has examined family functioning as a moderator variable. The Current Study: A secondary analysis of existing data from a NIDA funded study evaluating Brief Strategic Family Therapy vs. Treatment as Usual . Aim of Current Study Aim 1: To conduct exploratory analyses to determine if the relation of REM to treatment outcomes varies with the initial functioning of the family. Hypothesis: Family functioning would moderate the relationship between REM and treatment outcomes.

Results Hypothesis: Family functioning would moderate the relationship between race/ethnic-matching and the outcome variables. This hypothesis was not supported for the Hispanic or White youth. Baseline family functioning did moderate the relationship between race/ethnic-matching and the engagement outcome for African American adolescents (OR= 1.53, 95%CI = .57-4.09, p .01) African Americans who had lower levels of family functioning were more likely to be engaged in treatment if they were racially Probability of Non-engagement by Family Functioning for Matched and Non-matched African Americans Figure 1.

4 Synergy Enterprises Alyssa Forcehimes, University of New Mexico Introduction One of the strongest determinants of addiction treatment outcome is the relationship between the provider and the patient (McLellan, Woody et al., 1998) Both motivational interviewing (MI) and motivational enhancement therapy (MET) are rooted in a belief that change is facilitated through a strengthening of a collaborative therapeutic relationship. The successful use of MI/MET may depend on the therapists ability to develop strong alliance (Miller & Rose, 2009) Therapeutic Alliance and Treatment outcome
A positive outcome was found in Project MATCH (Connors, Carroll et al. 1997), in which alliance was positively associated with percent days abstinent and negatively related to drinks per drinking day during both the treatment and follow-up periods Other studies have failed to find a significant relationship in alliance and treatment outcome for MI based interventions (Crits-Cristoph, et al. 2009) What might Influence Alliance: Looking at Potential Moderators Alliance may vary depending on ethnicity or gender matches (or mismatches) between the patient and therapist Some research supports patient/therapist similarity (matching) in developing alliance more successfully (Thompson, Worthington, et al., 1994), but findings are mixed (Fiorentine &
Hillhouse, 1999). Aim of this Study Examine the moderating effects of gender/race matching between therapists and patients on therapeutic alliance and substance use outcomes Method Identical measures were obtained in two CTN trials of MET: 3 sessions of individual MET vs. Treatment as Usual (TAU) (CTN 0004) 3 sessions of individual MET delivered in Spanish vs. TAU delivered in Spanish (CTN 0021) The two studies included 64 females and 281 males with a mean age of 33.7 (SD = 9.2). 43% of participants reported their race as white, 30% reported Latino, 26% reported
other, and 1% reported African American Method, continued Measures The Helping Alliance Questionnaire-II (HAQ-II) The Addiction Severity Index-Lite Posttreatment Attitudes and Expectations Questionnaire Procedure HAQ-II, administered at the end of 3 sessions of treatment Therapists also completed a parallel version of the HAQ ASI-Lite, administered at the 4 week follow-up Patients perception of their therapists race or gender was extracted from the Posttreatment Attitudes and Expectations Questionnaire Analytic Plan Relationship between variables examined using
ANCOVAs Primary outcome variable was self-reported days of alcohol and drug use at week 4 assessed with ASI possible range: 0-360; 30 days for each of the 12 drug categories; observed range 0-100. Covariates HAQ-II patient and therapist scores and baseline substance use days Fixed variable Race or gender match Both HAQ-II scores were centered so intercept would be at the means of these scores instead of 0. Log transformation was applied to the outcome variable to reduce its skewness Effect size indicated by Cohens d Hypotheses (1) Patients perception of their therapists race will affect the
amount of substance use, defined as self-reported days of substance use at the end of the active phase of treatment, and patients perception will moderate the relationship between therapeutic alliance, defined by patient as well as therapist scores on the HAQ-II at the end of the active phase of treatment, and substance use. (2) Patients perception of their therapists gender will affect the amount of substance use, defined as self-reported days of substance use at the end of the active phase of treatment, and patients perception will moderate the relationship between therapeutic alliance, defined by patient as well as therapist scores on the HAQ-II at the end of the active phase of treatment, and substance use. Results: Hypothesis 1 As hypothesized, racially matched patients reported significantly fewer days of drug use (t(341) = -2.40, p = 0.02, d = -0.26). This effect equals to a 26% reduction in days of substance use from 5.2 to 3.9. However, racial match was unrelated to patient perceived helping
alliance (t(341) = 0.65, p = 0.52, d = 0.07). When HAQ-II therapists scores were included in the model, racially matched patients again reported significantly fewer days of drug use (t(341) = -2.36, p = 0.02, d = -0.26). Race matching significantly moderated the relationship between helping alliance perceived by therapists and substance use (t(341) = 2.03, p = 0.04, d = 0.22, fig. 1). There were no differences in matching effects between CTN 0004 and 0021. Results: Hypothesis 1 Results: Hypothesis 2 Gender matched patients reported significantly more days of drug use (t(341) = 2.17, p = 0.03, d = 0.23, fig. 2; a 57% increase from 3.4 to 5.3 days,) even after HAQ-II therapists scores were included in the model (t(341) = 2.01, p = 0.045, d = 0.22). Perceived gender similarity did not significantly affect the level of helping alliance indicated by patients (t(341) = 1.72, p = 0.09, d = 0.19) or therapists (t(341) = 0.56, p = 0.58, d = 0.06).
There were no differences in matching effects between CTN 0004 and 0021. Results: Hypothesis 2 Discussion Some unexpected findings: Matches in race resulted in significantly less substance use compared to patients and therapists whose race did not match. Therapists ratings of alliance varied by race matching, but patients ratings didnt. This suggests that therapists in this study seemed to have an easier time building alliance when working with a patient whose race matched their own. Unlike matches in race, matches in perceived gender between therapist and patient do not seem to be a helpful in decreasing substance use. Patients who perceived their therapists gender to be the same as their own gender actually had more days of substance use. Gender similarity also didnt increase therapeutic alliance as perceived by patients or therapists
Limitations A few limitations are worthy of mention when interpreting these results: This study only examined patients perceptions of gender and race. It cannot be assumed that the therapists had the same impression, and it remains unknown whether these impressions might have resulted in different outcomes. Asking patients about their therapists race may have been confusing for patients who were Latino or Hispanic, since many consider Latino to be an ethnic group rather than a race. Race may have been defined differently, thus results may have differed if the question would have been Was your counselor the same ethnicity as you? There were many more males than females in this study, which may have influenced the results. There were also very few African Americans, which is too few to make conclusions about matching African American patients with same race therapists. Summary Overall, findings from this study support a
recommendation of matching patients to providers of the same race, but do not support a recommendation of routinely matching patients to providers of the same gender.
