Introduction. There have been no scales specifically developed to assess physician-patient communication behaviors (PPCB) in\r\nthe sub-Saharan population. Aim. We revised an existing PPCB scale and tested its psychometric properties for HIV patients in\r\nKenya. Methods. 17 items (five-point scale) measuring PPCB were initially adopted from the Matched Pair Instrument (MPI).\r\nBetween July and August 2011, we surveyed a convenient sample of 400 HIV adult patients, attending three Academic Model\r\nProviding Healthcare program (AMPATH) clinics in Eldoret, Kenya. Of these 400, eight also participated in cognitive interviews,\r\nand 200 were invited to return after one week for follow-up interviews; 134 (67%) returned and were interviewed. Construct and\r\ncontent validity were established using an exploratory factor analysis, bivariate analyses, internal consistency, test-retest reliability\r\nand cognitive interviews. Results. Construct and content validity supported a one-dimensional measure of 13 PPCB items. Items\r\nassessed physiciansââ?¬â?¢ effort to promote a favorable atmosphere for interaction with HIV patients. Biases associated with encoding\r\nand comprehension of specific terms, such as ââ?¬Å?discussion, involvement or concerns,ââ?¬Â were noted. Internal consistency (Cronbachââ?¬â?¢s\r\nalpha = .81) and one-week retest reliability scores (.82) supported the reliability of the 13-item scale. Discussion. The revised PPCB\r\nscale showed acceptable validity and reliability in Kenya.
