    Abstract:
    Decision-making related to pregnancy planning is complex and human immunodeficiency virus (HIV) may further complicate the process. With increasing rates of pregnancy among individuals affected by HIV, the need to understand decision-making is imperative. The primary objectives of this pilot study were to confirm the feasibility of using discrete choice experimentation (DCE) to elicit an understanding of this process and to determine the acceptability of the choice factors that were included in two novel DCEs, while gathering a preliminary understanding of preference. The choice attributes were risk of vertical HIV transmission, risk of horizontal HIV transmission, cost, probability of conception, method of conception, and travel time. Thirteen respondents completed a DCE for serodiscordant couples in which the female partner was HIV-positive, and 12 respondents completed a DCE for seroconcordant couples. All respondents' utility for an increased chance of a successful pregnancy was positive and statistically significant. In the serodiscordant dyads, the attributes of risk of horizontal transmission, risk of vertical transmission, a 5-h travel time to clinic, and cost were significantly associated with decreased utility. In the seroconcordant dyads, only the attributes of chance of risk of vertical transmission and cost were significantly associated with decreased utility. The serodiscordant dyads preferred home insemination with a syringe and the seroconcordant couples preferred conception methods within fertility clinics, over condomless sex with timed ovulation. On average, participants were willing to pay more for greater chance of conception and less willing to pay for increased risk of transmission. Couples affected by HIV are willing to participate in a DCE and the attributes that were included all seem relevant except risk of vertical transmission. There are various real-life trade-offs that are made during pregnancy planning with HIV and better understanding of these can be useful for clinicians during preconception counseling.
