The treatment optimism beliefs included: ‘New treatments for HIV have brought hope for a cure’; ‘HIV will soon be a controllable disease like diabetes’; and ‘There will be a cure for HIV in the next Seliciclib few years’. A six-point scale was used for responses to questions about infectiousness beliefs and treatment optimism, with 1 indicating ‘strongly disagree’ and 6 indicating ‘strongly agree’. Mean scores were computed for both infectiousness beliefs (α=0.77) and treatment optimism (α=0.66). The AUDIT consists of 10 items designed to identify risks for alcohol abuse and dependence

[26]. The first three items of the AUDIT represent the quantity and frequency of alcohol use and the remaining seven items concern problems arising from drinking alcohol. AUDIT scores range from 0 to 40, with scores of ≥8 indicating high risk for problem drinking. This scale is an abbreviated version of the original DAST, designed to identify drug-use-related problems in the past year [27]. The DAST is internally consistent and has demonstrated time stability and acceptable sensitivity

and specificity in detecting drug abuse. Scores range from 0 to 10. We examined IDH inhibitor factors associated with having recently been diagnosed with an STI among men and women living with HIV/AIDS. Participants who had been diagnosed with an STI during the 6-month window were compared with those who did not have an STI in that time period using logistic regressions, reporting odds ratios, 95% confidence intervals and significance. We also tested for differences between STI groups in sexual behaviours, infectiousness beliefs and HIV treatment optimism in analyses that included current viral load as a moderating variable. Specifically, we conducted STI diagnosis (not having had a recent STI or having

had a recent STI) × viral load (detectable, undetectable or not known) analyses of variance with sexual behaviours entered as the dependent variables. These 2 × 3 analyses of variance yielded main effects for having had a recent STI diagnosis and viral load, and the interaction between recent STI diagnosis and viral load. A multivariate analysis was subsequently performed in which all factors found to differ between STI groups at the P<0.05 level of significance in the univariate analyses were entered. We used multivariate logistic regression to simultaneously enter variables 3-oxoacyl-(acyl-carrier-protein) reductase in a model differentiating participants who did not have a recent STI and those who had been diagnosed with an STI. Because sexual behaviours were highly skewed, we transformed these variables using the formula log10(X+1). Statistical significance was defined as P<0.05. Among the 490 participants, 51 (10%) reported having been diagnosed with an STI in the past 3 months at the initial assessment and 19 (4%) had been diagnosed in the subsequent 3 months, yielding a total of 70 (14%) HIV-positive men and women reporting STI diagnoses in the 6-month window.
