Two hundred and seven persons taking antiretroviral HIV medications rated a
nticipated affective responses to two vignettes depicting different medical
feedback situations. Participants were randomly assigned to a medical feed
back vignette which varied between participants by (a) the direction of HIV
viral load change (increase, decrease, no change) and (b) whether or not a
medication change was recommended by the physician. The first experimental
vignette was always followed by a second vignette depicting a viral load d
ecrease (indicating treatment success in suppressing the virus). A mixed 3
(viral load change) x 2 (medication change) x 2 (within-subjects factor) fa
ctorial design was used. Significant differences in anticipated affective r
esponses to treatment outcome situations were found, suggesting feedback ab
out success or failure of treatment regimens impacts psychosocial adjustmen
t of persons living with HIV.
