Using motivational interviewing to promote adherence to antiretroviral medications: a randomized controlled study

The primary aim of this study was to test an intervention to support antiretroviral medication adherence among primarily low-income men and women with HIV. The study was a randomized controlled trial (Get Busy Living) with participants assigned to treatment (Motivational Interviewing [MI]) and control groups. Participants were recruited from an HIV/AIDS clinic in Atlanta, Georgia, US. Of those referred to the study, 247 completed a baseline assessment and were enrolled with 125 randomized to the intervention group and 122 to the control group. Participants were patients beginning antiretroviral therapy or changing to a new drug regimen. The intervention consisted of five MI sessions delivered by registered nurses in individual counselling sessions. Participants were paid for each session attended. The intervention sought to build confidence, reduce ambivalence and increase motivation for ART medication-taking. Medication adherence was measured by the Medication Event Monitoring System (MEMS) from the time of screening until the final follow-up conducted approximately 12 months following the baseline assessment. Participants in the intervention condition showed a trend towards having a higher mean percent of prescribed doses taken and a greater percent of doses taken on schedule when compared to the control group during the months following the intervention period. This effect was noted beginning at about the eighth month of the study period and was maintained until the final study month. Although the finding was weaker for overall percent of prescribed doses taken, the results for the percent of doses taken on schedule suggests that the MI intervention may be a useful approach for addressing specific aspects of medication adherence, such as adherrence to a specified dosing schedule.     

The role of self-efficacy and motivation to explain the effect of motivational interviewing time on changes in risky sexual behavior among people living with HIV: a mediation analysis

Little is known about the amount of Motivational Interviewing (MI) needed to reduce risky sexual behavior among People Living with HIV/AIDS (PLWHA) or the roles self-efficacy and motivation to practice safer sex play. Among 183 PLWHA who received safer sex MI and were surveyed every 4 months over a 12 month period, we used hierarchical negative binomial regression models to examine the association between amount of counseling time and sexual risk behavior. We performed mediation analysis to evaluate whether changes in self-efficacy and motivation explained this association. This study found that as MI time and number of provided sessions increased, participants’ sexual risk behavior decreased. The effect of MI time and number of sessions on sexual behavior was mediated by self-efficacy but not by motivation to practice safer sex.     

Increasing the confidence of nursing staff to address the sexual health needs of people living with HIV: the use of motivational interviewing

The need to promote safer sexual behaviour has taken on new urgency in the UK because of large increases in the number of sexually transmitted infections (STIs). The sexual health needs of people living with HIV and AIDS (PLHA) also require attention as part of health promotion efforts. Many sexual health clinics are however struggling with high demand and limited resources. Within this context, this paper describes an innovate attempt at STI prevention with PLHA. Specifically, nursing staff were trained in the use of motivational interviewing to address sexual health issues and safer sexual behaviour in PLHA. We describe the training package and the impact upon participants. We conclude that by providing a positive training experience, front-line health staff that see the highest volume of PLHA with repeat STIs, can be assisted in developing their skills and confidence in prevention work with clients.     

Intervention to reduce adolescents sexual risk behaviors: a randomized controlled trial

OBJECTIVE: To test the efficacy of a behavioral intervention designed to decrease risk sexual behaviors for HIV/AIDS and unplanned pregnancies in Mexican adolescents. MATERIAL AND METHODS: Randomized controlled trial with four follow ups; 832 adolescents recruited from high schools, age 14-17, were randomly assigned to the experimental or control group. The six hour intervention used active learning strategies, and was delivered in two sessions on two consecutive Saturdays. The study was carried out in Monterrey, Mexico, 2002-2005. RESULTS: GEE analysis indicated no differences in sexual relationships intentions between the two conditions, however, the experimental group had higher intentions to use condoms and contraceptives (mean differences 0.15 and 0.16, CI 95%) in the next three months, as compared with the control group. Theoretical variables, such as control beliefs, were significant mediators of the intervention. CONCLUSIONS: The behavioral intervention represents an important effort in promoting safe sexual behaviors among Mexican adolescents.     

Couple-focused support to improve HIV medication adherence: a randomized controlled trial

OBJECTIVE: To assess the efficacy of a couple-based intervention to improve medication-taking behavior in a clinic population with demonstrated adherence problems. DESIGN: A randomized controlled trial (SMART Couples Study) conducted between August 2000 and January 2004. SETTING: Two HIV/AIDS outpatient clinics in New York City. PARTICIPANTS: Heterosexual and homosexual HIV-serodiscordant couples (n = 215) in which the HIV-seropositive partner had < 80% adherence at baseline. The sample was predominantly lower-income racial/ethnic minorities. INTERVENTION: Participants were randomly assigned to a four-session couple-focused adherence intervention or usual care. The intervention consisted of education about treatment and adherence, identifying adherence barriers, developing communication and problem-solving strategies, optimizing partner support, and building confidence for optimal adherence. OUTCOME MEASURES: Medication adherence at week 8 (2 weeks after the intervention) compared with baseline, assessed with a Medication Event Monitoring System cap. RESULTS: Intervention participants showed higher mean medication adherence at post-intervention when compared with controls whether adherence was defined as proportion of prescribed doses taken (76% versus 60%) or doses taken within specified time parameters (58% versus 35%). Also, participants in the intervention arm were significantly more likely to achieve high levels of adherence (> 80%, > 90%, or > 95%) when compared with controls. However, in most cases, effects diminished with time, as seen at follow-up at 3 and 6 months. CONCLUSION: The SMART Couples program significantly improved medication adherence over usual care, although the level of improved adherence, for many participants, was still suboptimal and the effect was attenuated over time.     

A randomized controlled pilot study of motivational interviewing for patients with psychotic and drug use disorders

AIMS: This pilot study examined the efficacy of a two-session motivational interview adapted for dually diagnosed psychotic and drug-related disordered patients (DDMI) in comparison to a two-session standard psychiatric interview (SI). DESIGN: The study used a randomized controlled trial design. Participants received either DDMI or SI and were assessed at baseline, 4-, 8- and 12-week follow-up points. The principal analysis for examination of treatment effects across time was a random effects regression model. SETTING: Both DDMI and SI interviews served as pre-admission intake interventions to an ambulatory specialty dual diagnosis intensive out-patient and partial hospital program. PARTICIPANTS: Forty-four treatment-seeking participants (DDMI = 24; SI = 20) who had co-occurring psychotic and drug-related disorders were assigned randomly to the treatment conditions. Measurements Primary outcomes were days of primary drug use, secondary drug use, alcohol use and psychotropic medication adherence, proportion of participants admitted into the program and days of attendance. FINDINGS AND CONCLUSIONS: DDMI and SI resulted in improved treatment outcomes, but there were no main effects for the sample as a whole. Separate examination of primary cocaine and primary marijuana using subsamples, however, suggested that DDMI resulted in significantly better primary drug treatment outcomes for the cocaine-using group, whereas SI resulted in significantly better primary drug treatment outcomes for the marijuana-using group. These findings indicate that MI may not work equally well for all types of psychotic disordered dually diagnosed patients and that alternative approaches may be as effective in fostering improved substance use treatment outcomes for subgroups of these individuals.     

Effect of HIV antibody testing and AIDS education on communication about HIV risk and sexual behavior. A randomized, controlled trial in college students.

OBJECTIVE: To evaluate the effects of human immunodeficiency virus (HIV) antibody testing and education about HIV infection on communication about sexual risk behaviors for HIV transmission. DESIGN: Randomized, controlled trial with three arms. SETTING: University student health center. PATIENTS: Of 2196 heterosexual university students attending the student health clinic for medical care, 435 were interested in education about HIV and HIV testing and were randomly assigned to three groups. Follow-up at 6 months was done in 370 subjects (85%): 90 control subjects, 144 subjects who received education alone, and 136 subjects who received education plus HIV testing. MEASUREMENTS AND RESULTS: Subjects who received HIV testing plus education questioned sexual partners about their HIV status more than subjects receiving education alone or those in the control group (56%, 42%, and 41% of subjects, respectively; P = 0.01). No consistent differences among groups in the number of sexual partners or in the use of condoms were found at follow-up. CONCLUSIONS: Heterosexual university students who received education about HIV infection plus HIV testing had increased communication with sexual partners about the risk for HIV infection after 6 months. Further reduction in risk behaviors for HIV transmission may require additional interventions in this population.     

Prevention of sexual risk behavior for HIV infection with women

This paper defines the components of gender-specific interventions for HIV infections for women, i.e. negotiation skills with male partners for condom use, integration of strategies against HIV and other STD infections and for contraception, the urgent need for female controlled methods, the importance of the inclusion of heterosexual men and an expansion to couples in prevention programs. This paper also presents a critical update in HIV prevention articles for women since the beginning of the AIDS epidemic through March 1996. All reviewed interventions were conducted in the U.S., Canada or Puerto Rico and described a psychological, behavioral, or educational component that addressed sexual risk reduction and included a behavioral evaluation. Manual and computer searches identified 47 studies that targeted women and provided a female-specific analysis of intervention effects. Overall, the findings demonstrate that HIV prevention programs can be effective in reducing risky sexual behavior among women. Program effectiveness varied by intervention type, session duration, and whether studies included women alone or both men and women. The most efficacious HIV prevention programs were specifically directed toward women, focused on relationship and negotiation skills, and involved multiple, sustained contacts. Evidence also indicated that community-level interventions hold promise. It is recommended that outcomes for women be expanded to include strategies beyond the male condom, such as refusing or avoiding unsafe sex or using the female condom.
