“…This design allowed efficient estimation for the main effects of the seven dichotomous attributes with a minimum number of eight hypothetical vaccines, under the assumption that the impact of the factors are additive, that is, there are no interactions among the factors [38]. Although the additivity assumption creates restrictions, we believe it is appropriate to focus on the main effects for our study given its pioneering nature in assessing the acceptability of multi-attribute HIV vaccines.…”

HIV vaccines offer the best long-term hope of controlling the AIDS pandemic; yet, the advent of HIV vaccines will not ensure their acceptability. We conducted a cross-sectional survey (n = 143), incorporating conjoint analysis, to assess HIV vaccine acceptability among participants recruited using multi-site (n = 9), venue-based sampling in Los Angeles. We used a fractional factorial experimental design to construct eight hypothetical HIV vaccines, each with seven dichotomous attributes. The acceptability of each vaccine was assessed individually and then averaged across participants. Next, the impact of each attribute on vaccine acceptability was estimated for each participant using ANOVA and then analyzed across participants. Acceptability of the eight hypothetical HIV vaccines ranged from 33.2 (S.D. 34.9) to 82.2 (S.D. 31.3) on a 0-100 scale; mean = 60.0 (S.D. 21.9). Efficacy had the greatest impact on acceptability (22.7; CI: 18.5-27.1; p < 0.0001), followed by cross-clade protection (12.5; CI: 8.7-16.3, p < 0.0001), side effects (11.5; CI: 7.4-15.5; p < 0.0001), and duration of protection (6.1; CI: 3.2-9.0; p < .0001). Route of administration, number of doses and cost were not significant. Low acceptability of "partial efficacy" vaccines may present obstacles to future HIV vaccine dissemination. Educational and social marketing interventions may be necessary to ensure broad HIV vaccine uptake.

Economists have developed a variety of methods to measure the values of environmental goods and services. Conjoint analysis (CJ) is a technique developed by mathematical psychologists to establish the structure of preferences across multi-attribute alternatives. It is a type of stated-preference method that has captured the attention of economists for purposes of analyzing preferences toward environmental goods and services. This paper outlines the applicability of CJ to environmental valuation, illustrates applications and valuation issues in the literature, and presents an application of CJ to valuing a Pennsylvania watershed quality improvement.

“…One of those is called a discrete choice experiment (DCE), which identifies the wishes and preferences of a specific group of people. The willingness to pay (WTP) for (lifesaving) medical services can be calculated from a DCE, provided that costs are incorporated into that DCE 6 . Worldwide hardly any research has been performed to examine the attitude of the general public towards HEMS, including the marginal willingness to pay for lives saved by HEMS.…”
