1) Background. Several versions of a 43-minute soap opera video to reduce HIV risk were created to provide feedback tailored to the level of HIV sex risk in young urban women. The application processes the participants' answers to an audio computer assisted self interview (ACASI). The Decision Support System (DSS) executes an algorithm to determine level of HIV sex risk.

(2) Objective/purpose. To extend an ACASI to include DSS functionality to deliver tailored video health promotion; and to compare branching functionality, technical performance/feasibility, and user acceptability of the ACASI/ DSS prototype on handheld, laptop, and desktop computers.

(3) Methods

Hypothesis. The acceptability of the ACASI/DSS on the handheld will be similar to that on a Tablet PC and desktop computers.

Sample. The sample was 180 women, 86% were African American, aged 18 to 29, in recent relationships with men. Participants were randomized into three groups: Desktop (n=60), Tablet PC (n=60), and handheld (n =61).

Data Collection. A downtown storefront office, a community center, public housing, and STD clinic in the urban Northeast.

Data analysis. Descriptives, One-way ANOVA by type of computer.

(4) Results. The majority was at risk for HIV and received the appropriate video. As hypothesized, there was no statistically significant difference between groups on computer acceptability (F (2, 178) = .73, p = .48).

(5) Discussion/conclusions. Preliminary findings support the feasibility and acceptability of small handheld devices to complete an interactive interview and view full length videos in young urban women. Handhelds have the advantages of privacy and portability. This research addresses a gap in the literature on delivering a fully functioning DSS and tailored video feedback on handheld devices as a means to reduce HIV risk in young urban women. Growing popularity of small portable devices to run videos suggests a new paradigm to deliver health promotion.

Learning Objectives:
1. The attendee will describe a study to evaluate a decision support system (DSS) to deliver tailored video health promotion; and to compare branching functionality, technical performance/feasibility, and user acceptability of the ACASI/ DSS prototype on handheld, Tablet PCs, and desktop computers. 2. The attendee will describe the criteria to evaluate a new DSS/ACASI prototype 3. Based on the results of this study, the attendee will discuss the potential of a new generation of handheld devices to deliver health promotion videos to young urban women at risk for HIV
