The current study therefore sought to establish the prevalence and social demographic factors associated with Secondary Traumatic Stress, Burnout and Compassion Satisfaction among Nurses working at selected Teaching Hospitals in Lusaka, Zambia. Methods: A correlational design employing a self-administered questionnaire adapted from version five of the Professional Quality of Life scale was used to collect data from 250 nurses drawn using proportional stratified sampling method. The resulting data were analyzed using version 23 of the Statistical Package for Social Sciences (SPSS). Hierarchical multiple linear regression analysis was used to identify predictors of Secondary Traumatic Stress and Burnout. Findings: Whilst the majority of respondents reported average levels of Secondary Traumatic Stress and Burnout, about a quarter reported high Secondary Traumatic Stress and Burnout scores at 23% and 26% respectively. Only 81 (32.4%) scored high on Compassion Satisfaction. Social demographic factors including;working in the main Intensive Care Unit, and being married accounted for the greatest variance in Secondary Traumatic Stress (R<sup>2</sup> = 0.237, p Conclusion: Findings of the current study signify a need to institute measures to help nurses cope with the deleterious psychological effects of constant engagement with those in distress and to foster Compassion Satisfaction.展开更多

Methods: The convenient sampling method was used to investigate the professional quality of life (proQOL) questionnaire Version 5 and the self-designed demographic data of 82 elderly nurses working in two elderly care institutions. Result: From this score, it can be seen that the occupational burnout problem of elderly nursing staff in the two nursing homes is the most significant, with empathy and secondary trauma emergency at a moderate level. After controlling the demographic variables, the working hours and monthly income level had a significant impact on nurses’ job burnout. Conclusion: Due to the particularity and high intensity of elderly nurses’ work, their physical and mental health faces many challenges, which affect their quality of life. At present, efforts will be made to reduce work pressure, increase wages and benefits, and thereby improve the quality of life.展开更多
