Developing Rectal USPE Measures

Evaluating User Perceptions and Experiences of Dual Compartment Microbicide Formulations. Project 5.1: Developing Rectal USPE Measures

• Status: Completed
• Phase: N/A

Summary

The purpose of this study is to: (a) adapt existing vaginal USPE items/instruments for evaluation of similar elements of rectal compartment use; (b) develop these scales using 3 distinct semi-solid formulations that represent a range of physicochemical and rheological properties of microbicides that are currently being designed for dual compartment use; and (c) develop novel USPE instruments to capture the experience of product use in the context of receptive anal intercourse (RAI) in both male and female cohorts.

Detailed description

HIV prevention is a global public health priority. Providing efficacious prevention methods that have the greatest likelihood of use will have a profound impact on the public's health. Critical to their use is "acceptability." However, current conceptualizations of adherence and acceptability fail to fully articulate and account for patterns of use and non-use. Formulation properties are critically important to both drug delivery and the user experience. Microbicide developers thus have the opportunity to directly control a formulation's impact on acceptability and adherence to product use, as well as biological product performance. Microbicide products can and should be developed such that they achieve performance standards for both these behavioral (user experience) and biological (efficacy) functions. By incorporating the user experience early on in the product development process, developers will have the greatest chance of providing at-risk individuals with the best prevention methods science can provide. Developing prevention products that can be used in the vagina and/or the rectum and that optimize the user experience in both compartments increases the likelihood that these products will be used consistently and correctly. The impact on global public health has the potential to be far-reaching, decreasing HIV and sexually transmitted infections (STI) incidence and prevalence in both women and men. Methodology and Data Collection: This is a formative study in which volunteers (N\~20-30; \~8-20 males; \~8-20 Females) will first be prescreened for basic study eligibility using a brief questionnaire. Those who are interested in the study and are eligible based on their responses to the prescreen will then complete a STI/HIV screening and pregnancy test (for females). During the course of the study, participants will evaluate 3 study products (i.e., distinct semi-solid formulations that represent a range of physicochemical and rheological properties). Each participant will be randomly assigned to the order in which they will evaluate the 3 products. After a sexual encounter that includes RAI and study product use, participants will be required to complete a web survey about their experience with the study product.
