title: Mediation effect of perceived behavioural control on intended condom use: applicability of the theory of planned behaviour to money boys in China.
abstract: BACKGROUND
  Money boys (MBs) are male sex workers who sell sex to men who have sex with men. The objectives of this study were to assess (a) the sexual HIV risk of MBs; (b) the ability of the theory of planned behaviour (TPB) to predict MBs' intentions to use condoms; and (c) the manner in which TPB constructs (attitudes towards condom use, subjective norms and perceived behavioural control) combine to influence condom use intentions.
  
  
  METHODS
  Participants came from 10 MB-frequented clubs in two cities in China. Multiple regression and path analytic models were used to test inter-relationships among the TPB constructs.
  
  
  RESULTS
  Seventy-eight percent of the 122 MB participants reported having used condoms for every anal sex act. About one-third reported having had female sexual partners in the past 2 months; of these MBs, half (53%) used condoms for every sex act. A revised model using TPB constructs accounted for 52% of the variance of condom use intentions and revealed that perceived behavioural control was a mediator in pathways beginning with attitudes and ending with condom use intentions, and beginning with subjective norms and ending with intentions.
  
  
  CONCLUSIONS
  The findings suggest that a revised model of TPB applies to condom use intentions among Chinese MBs. It may be appropriate to adapt HIV interventions that are grounded in TPB and that have been shown to be effective elsewhere for use with Chinese MBs. HIV interventions for this population should give perceived behavioural control and its predictors special consideration.
