MedChemExpress HIV-RT inhibitor 1 Uestions were adapted from validated patient self-report survey instruments [9,10]. We converted responses for each question to a 0- to 10-point scale. Overall patient satisfaction was measured by averaging the response values of these 2 questions. Construct reliability was evaluated by calculating composite reliability and average variance extracted. We used recommended thresholds of 0.70 and 0.50, respectively [11?4]. Medication adherence. A validated, single-item measure assessed adherence to HAART. The item stated, “Many patients find it hard to take HIV medicines as their doctor prescribes them. In the past 4 weeks, how would you rate your ability to take all your HIV medicines as your doctor prescribed?” The 6-point response scale ranged from “very poor” to “excellent” [15,16]. This item has been validated against medication event monitoring system data, an objective measure of adherence [15], and has anOverall patient satisfaction.Relationship between Patient Satisfaction and Adherence to HIV Care. We compared overall patient satisfaction scoresbetween participants with adequate versus inadequate retention in HIV care, “excellent” versus non-“excellent” adherence to HAART, and suppressed versus unsuppressed HIV replication using 1655472 the Wilcoxon Rank-Sum Test. Bivariate analyses. We performed bivariate analyses between potential purchase 125-65-5 control variables (demographic, health status, behavioral characteristics, and clinic utilization variables listed in Table 1) and all dependent variables in the structural equation model (patient satisfaction, retention in HIV care, adherence to HAART and HIV suppression). To be parsimonious in selecting control variables, we included only variables achieving a significance level of p,0.10 in bivariate analyses with at least 2 of the 4 dependent variables. Structural equation modeling. We used structural equation modeling (SEM) to examine hypothesized relationships between patient satisfaction, retention in HIV care, adherence to HAART, and HIV suppression. SEM is a multivariate statistical method that: 1) inputs empirical data and qualitative causal assumptions from theory-based models, 2) allows for the simultaneousPatient Satisfaction to Improve HIV AdherenceTable 1.
