This article investigates the antecedents and consequences of source credibility within the context of the relatively new but growing phenomenon of Chief Executive Officer (CEO) endorsers. The study results indicate that source credibility is a central determinant of a CEO endorsers’ ability to effect desired outcome states. Results also indicate that the effect of message source credibility on purchase intentions, though strong, is not direct because beliefs about critical product attributes mediate the effect of a message source’s credibility on behavioural intentions. The results of the study also indicate that models of source credibility derived from the celebrity endorser literature do not generalize to the CEO endorser context. Specifically, the attractiveness and expertise of the message source had no significant impact on receivers’ perceptions of credibility.

Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS) is a prevalent, refractory pelvic pain condition characterized by pain in the pelvic area and urinary frequency, largely unresponsive to medical interventions. This study used multiple mediations to test the associations of validated pain appraisal and behavioural coping strategies between pain and quality of life. Patients (N = 175) were recruited from tertiary care urology clinics and completed questionnaires. Exploratory factor analyses were conducted on four individual measures (Chronic Pain Coping Inventory, Survey of Pain Attitudes – Control subscale, Center for Epidemiologic Studies Depression Scale, and Pain Catastrophizing Scale), then on the empirically derived factors that produced four factors to be used in regression and multiple mediation models: illness-focused behavioural coping, catastrophizing, wellness-focused behavioural coping, and depression. In regressions, CP/CPPS patient symptoms (p < .01), illness-focused behavioural coping (p < .01) and wellness-focused behavioural coping (p < .05) predicted physical quality of life, while catastrophizing (p < .01) and illness-focused behavioural coping (p < .05) predicted mental quality of life. Mediation analyses showed that illness-focused behavioural coping strategies partially mediated the relationship between pain and physical quality of life, whereas catastrophizing and illness-focused behavioural coping strategies both fully mediated the relationship between pain and mental quality of life. These results identify catastrophizing and illness-focused coping as key psychosocial targets for interventions for patient quality of life in CP/CPPS. / Thesis (Master, Psychology) -- Queen's University, 2013-08-27 17:07:11.853
