Study summary

This study combined, adapted and tested motivational interviewing (MI) and the Community Reinforcement Approach (CRA) as a culturally congruent treatment approach for Native Americans. This pilot-feasibility research was conducted in collaboration with a Southwest Tribe. The specific aims of this project were: Aim 1. To develop, in collaboration with the Tribal community, a combination of MI and CRA (MICRA) that is culturally adapted and includes a secondary focus on HIV/STD prevention; Aim 2. To develop and field test culturally-congruent research materials and procedures; Aim 3. To train Tribal behavioral health professionals in delivery of MICRA, and test (N=9) procedures for MICRA certification, supervision, and fidelity assurance; Aim 4. To conduct a pilot study (N=79) to estimate effect sizes for MICRA on key outcome variables with participants; and Aim 5. To estimate the types and prevalence of emotional distress and psychological and health problems likely to be encountered when treating substance use disorders in Native American populations.

MICRA Project was conducted in two phases: Phase 1 was a feasibility (N = 9) non-randomized one-group design wherein all participants received culturally adapted MICRA.

Phase 2 was a pilot (N = 79) comparing the effectiveness of MICRA and TAU. Following the screening and baseline interview, participants were randomized to receive MICRA or treatment as usual (TAU). Participants randomized to MICRA could receive up to a maximum of 16 to 20 therapy sessions with one of the MICRA counselors over the course of 16 weeks. In TAU, participants received standard outpatient services at the Tribal substance use disorder treatment center.

The primary hypotheses were: (1) the feasibility test (N=9) would yield improved percent days abstinent from all substances (excluding tobacco) from baseline to the 8-month follow-up, and (2) In the pilot randomized controlled trial of MICRA versus treatment as usual (TAU), the investigators hypothesized that percent days abstinent from all substances would be greater at the 12-month follow-up timepoint compared to TAU.

This study combined, adapted and tested motivational interviewing (MI) and the Community Reinforcement Approach (CRA) as a culturally congruent treatment approach for Native Americans. This pilot-feasibility research was conducted in collaboration with a Southwest Tribe. The specific aims of this project were: Aim 1. To develop, in collaboration with the Tribal community, a combination of MI and CRA (MICRA) that is culturally adapted and includes a secondary focus on Human Immunodeficiency Virus / sexually transmitted disease (HIV/STD) prevention; Aim 2. To develop and field test culturally-congruent research materials and procedures; Aim 3. To train Tribal behavioral health professionals in delivery of MICRA, and test (N=9) procedures for MICRA certification, supervision, and fidelity assurance; Aim 4. To conduct a pilot study (N=79) to estimate effect sizes for MICRA on key outcome variables with participants; and Aim 5. To estimate the types and prevalence of emotional distress and psychological and health problems likely to be encountered when treating substance use disorders in Native American populations.

MICRA Project was conducted in two phases: MICRA was conducted in two phases: Phase 1 was a feasibility (N = 9) non-randomized one-group design wherein all participants received culturally adapted MICRA. The purpose of Phase 1 was to (a) implement and test the draft version of the MICRA counselor manual, (b) test counselor fidelity monitoring procedures, (c) certify counselors in MI and CRA, (d) test the assessment procedures and basic aspects of the Manual of Operations, (e) certify the research assistant in assessment administration procedures, and (e) pilot the 4- and 8-month follow-ups.

Phase 2 was a mixed efficacy/effectiveness (hybrid) randomized controlled trial of MICRA (n=38) and TAU (n=41) with a parallel design and follow-up assessments at 4-, 8-, and 12-months post baseline. Following the screening and baseline interview, participants were randomized to receive MICRA or treatment as usual (TAU). Participants randomized to MICRA could receive up to a maximum of 16 to 20 therapy sessions with one of the MICRA counselors over the course of 16 weeks. In TAU, participants received standard outpatient services at the Tribal substance use disorder treatment center.

The primary hypotheses were: (1) the feasibility test of culturally adapted MICRA (N=9) would yield improved percent days abstinent from all substances (excluding tobacco) from baseline to the 8-month follow-up, and (2) In the pilot randomized controlled trial of culturally adapted MICRA versus treatment as usual (TAU), the investigators hypothesized that percent days abstinent from all substances would be greater at the 12-month follow-up timepoint compared to TAU.

Study arms

  • Active comparator
    Motivational Interviewing and Community Reinforcement Approach

    A psychosocial intervention culturally tailoring the combination of motivational interviewing (approximately 1-3 individual therapy sessions) and the community reinforcement approach (could include maximum range of 15-19 individual therapy sessions). Two tribal members were hired and trained to deliver this intervention and were located separately from the other arm.

    Behavioral: MICRA

  • Active comparator
    Treatment as Usual

    Treatment as usual (TAU) included an intake session and could include individual counseling, group counseling, or cultural education. Treatment as usual was provided by staff at the reservation based outpatient treatment center. There was no limit on number of sessions provided.

    Behavioral: TAU

What researchers measure

Primary outcomes

  1. Percent days abstinence from substances

    using the Form-90 for drugs (Form 90-D questionnaire), the investigators will examine percent days abstinent from all substances and conduct statistical tests to determine whether there is a significant difference between the treatment and comparison conditions

    Time frame: baseline to 12-month follow-up

Secondary outcomes

  1. Condom Use Self Efficacy (questionnaire)

    Condom Use Self-Efficacy Scale (questionnaire); the investigators will examine whether there are significant increases in condom use self-efficacy for the sample from baseline to 12-month follow-up

    Time frame: baseline to 12 month follow-up

  2. Native American Spirituality Scale (questionnaire)

    The investigators will examine whether spiritual beliefs and behaviors increase over time from baseline to the 12-month follow-up for the sample using the total score as well as the two subscales (spiritual beliefs and spiritual behaviors)

    Time frame: baseline to 12 month follow-up
