Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A randomized trial was conducted at drug diversion educational programs with a sample of 343 adult drug offenders who volunteered for the study. The trial tested three different interventions on HIV testing and condom use, with a 3 month follow-up. The study translated consistent basic research showing strong effects of memory practice on memory for new material. One of the conditions involved extensive memory practice of action plans involving HIV testing and condom use. Other conditions varied two active control interventions. Results showed that the memory practice condition led to a substantially larger odds of HIV testing than did the two control conditions. Condom use was also significantly more frequent in the memory practice condition than in one of the control conditions but was not significantly different from the second control condition.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study translated basic research from several areas of cognitive science to a new intervention procedure designed to reduce HIV risk and increase screening for HIV and other infections. A randomized trial was conducted (N = 343) to test effects on testing for infection (HIV and hepatitis B/C) and condom use frequency in a sample of drug offenders at risk for infection. Many populations of drug offenders are not currently receiving evidence-based prevention for HIV or hepatitis and are in need of effective interventions that can be used in existing drug programs. At three-month follow-up, the results revealed that the condition translating basic research on memory practice and integrative processing significantly increased the odds of infection testing as compared to two alternative conditions. This condition also significantly improved the extent of condom use, compared to a traditional health education condition. The results show promise for increased translation of basic research on memory to behavioral interventions on health and prevention science. Such procedures can be effectively applied in a complex field setting in existing drug diversion programs.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Participants were randomly assigned at the individual level to one of three different conditions within each drug diversion class.

Primary Study Purpose

SCREENING

Blinding Strategy

QUADRUPLE

Participants Caregivers Investigators Outcome Assessors

Participants were randomly assigned by computer algorithm to three different conditions, and the intervention took place over individually assigned computers with screens that were not observable by the care provider, investigator, or outcome assessor. The two control groups were designed to be "active," that is, designed to have some effects. Thus, there was no indication of which intervention might be more effective.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Health Education

This condition included live health education followed by health education videos on HIV risks, testing, and condom use. The videos were presented over laptop.

Group Type ACTIVE_COMPARATOR

Health Education

Intervention Type BEHAVIORAL

Videos (AIDSvideos.org) were presented on individually-assigned laptops and covered HIV risk, condom use, safe sex, and infection testing

Action Plan

This condition included live health education followed by computerized procedures focusing on action plans for HIV testing and condom use and some of the same health education videos in the Health Education condition.

Group Type ACTIVE_COMPARATOR

Action Plan

Intervention Type BEHAVIORAL

Participants selected situations for condom use and screening for HIV and hepatitis on individually-assigned laptops. They linked these situations to preventive behaviors regarding screening and condom use.

Memory Practice

This condition included live health education followed by computerized action plan procedures (as in the Action Plan condition), followed by several memory practice procedures also delivered over laptop. The memory practice procedures were designed to help participants more readily retrieve and use action plans in critical situations.

Group Type EXPERIMENTAL

Memory Practice

Intervention Type BEHAVIORAL

Participants engaged in several different types of memory practice procedures on assigned laptops. The procedures focused on memory for action plans for screening and condom use.
