The CoHD instrument required respondents to rate the importance of eight costs (eg, might lose the relationship) and ten rewards (eg, would bring us closer) in their decision about whether to self-disclose their HIV status. The participants were directed to respond with respect to a current (or hypothetical) sexual partner.Results: Internal consistency was acceptable (Cronbach’s α for the overall scale 0.82, costs 0.71, and rewards 0.86), as was stability (test–retest reliability overall 0.74, cost 0.63, and rewards 0.82). The CVI for the scale was 0.83, with items rated by subject experts ranging from 0.80 to 1.0. To determine structural validity, exploratory factor analysis extracted two subscales consistent with the original CoHD subscales. The Mandarin CoHD scores were significantly correlated with disclosure self-efficacy (indicating convergent validity), but they were unrelated to safer sex efficacy (indicating divergent validity). This criterion was tested by comparing the scores of PLWH who disclosed their HIV status (mean±SD 53.57±9.06) with those who did not disclose it (mean±SD 49.63±7.45); however, the difference was not statistically significant.Conclusion: The Mandarin version of the CoHD instrument demonstrates promising psychometric properties when assessing costs and rewards with respect to sexual partner disclosure. This suggests that it might be useful in research on partner notification strategies. In further studies, larger and more diverse samples and an analysis of responses for different disclosure targets are warranted. Moreover, whether the CoHD score is related to the decision of disclosure should be determined. Keywords: HIV, self-disclosure, sexual partner, partner notification, psychometric analysis, China
