Field Psychometric Testing of the Instrument for Assessment of Psychological Predictors of Well-Being and Quality of Life in People with HIV or AIDS

AIDS Behav. 2016 Jun;20(6):1360-9. doi: 10.1007/s10461-015-1253-1.


The Screenphiv, a screening measure for psychological issues related to HIV, was psychometrically tested in a study involving 744 HIV-infected people in Spain. Participants ages 18-82 (M = 43.04, 72 % men, 28 % women) completed an assessment protocol that included the Screenphiv and the MOS-HIV. A trained interviewer also collected relevant illness-related clinical data and socio-demographics from the participants. A confirmatory factor analysis was used to evaluate the goodness of fit of the Screenphiv's theoretical model and confirmed six first-order factors and two second-order factors [RMSEA (IC 90 %) = 0.07 (0.07-0.08)]. No floor or ceiling effects were observed for the scores. Cronbach's alphas were acceptable for all of the factors (from 0.65 to 0.92). Criterion-related validity also achieved; Screenphiv scores were related to socio-demographic and clinical variables and MOS-HIV summary scores. The Screenphiv is a reliable and valid measure, ready to use in research and clinical settings in Spain.
