A CONJOINT ANALYSIS STUDY OF PREFERRED CHARACTERISTICS FOR HOME-BASED SELF-SAMPLING FOR HPV (ID 9)
Abstract
Introduction
Home-based self-sampling for HPV can overcome barriers to clinic-based screening among African American (AA) women, who are under-screened for cervical cancer. The purpose of this study was to assess preferred characteristics for delivery of self-sampling kits (Delivery), return of kits (Return), and communication of results (Results).
Methods
Survey data were gathered at an Indiana AA health fair. Women evaluated scenarios that varied in terms of 3 dimensions: Delivery (mail, pharmacy pickup, or clinic pickup), Return (mail, pharmacy drop-off, or clinic drop-off), and Results (phone call, text message, or mail). A fractional factorial design produced 9 representative scenarios, each of which was rated on a 0 to 100 scale. Ratings-based conjoint analysis (RBCA) determined how each dimension influenced ratings. RBCA importance scores (IS) show how much each dimension contributes to ratings and part-worth utilities (PWU) indicate relative preferences for characteristics within each dimension.
Results
The 118 participants ranged in age from 21-65 (M=45). Across the 9 scenarios, overall willingness to self-sample had a mean of 60.9 (SD=31.3). The most important dimension (IS=40.6) was Return, with preferences for pharmacy drop-off (PWU=1.5) or mailed return (PWU=1.1) over clinic drop-off (PWU=-2.5). The next most important decisional factor (IS=31.9) was Delivery, with a preference for mailed delivery (PWU=1.5) over pharmacy pick-up (PWU=0.04) or clinic pick-up (PWU=-1.6). The least important decisional factor was Results (importance score=27.4), with participants preferring a phone call (PWU=1.0) over a text message (PWU=0.6) or mailed delivery of results (PWU=-1.6).
Conclusions
HPV self-sampling was generally acceptable to these AA women, but respondents indicated clear preferences regarding Delivery, Return, and Results. Clinic pick-up and drop-off were viewed relatively negatively, and women preferred a more personalized delivery of results via phone call. If confirmed, these preliminary findings could inform future home-based self-sampling for HPV interventions.
