Abstract
The aims of this study were to (a) examine the relationships between personal resources (psychological capital), job resources (social support, job characteristics), and job performance; and (b) investigate the effectiveness of work engagement as a mediator in the above relationships. Conservation of resources (COR) theory (Hobfoll, 1989) and Blau’s (1964) social exchange theory (SET) were utilized in developing the research framework. Job performance was operationalized as comprising of two broad dimensions: task performance and contextual performance. Particularly, task performance consists of four dimensions: informational supportive behaviour, coordination of care behaviour, interpersonal supportive behaviour, and technical care behaviour. Meanwhile, contextual performance was considered in two dimensions, which are volunteerism behaviour and task supportive behaviour. Two forms of resources (personal resources and job resources) that may influence individual job performance have been examined in this study. Personal resources comprise of psychological capital (resilience, hope, optimism, self-efficacy). Whereas, job resources consist of social support (supervisor support, co-worker support) and job characteristics (job feedback, task significance, job autonomy). A total of 1254 staff nurses and 496 supervisors (sisters) from 11 general hospitals in Peninsular Malaysia, representing a response rate of 83.6%, participated in this study. Data were obtained via self-administered questionnaires. Nine broadly hypothesized relationships were tested using a sample of 1254 matched supervisor-subordinate pair questionnaires. Hierarchical regression analyses were conducted to test the hypotheses posited in this study. The regression results indicated that: (1) dimensions of psychological capital, social support, and job characteristics were positively and significantly related to several dimensions of task performance and contextual performance, (2) dimensions of psychological capital, social support, and job characteristics were found to be positively and significantly related to work engagement, (3) work engagement had a positive and significant relationship with several dimensions of job performance, and (4) work engagement mediates the relationship between psychological capital, social support, job characteristics, and job performance. Theoretical and practical implications of the study as well as suggestions for future research were discussed.
