Purpose: To investigate the association between using online support groups (OSGs) and health-related quality of life (HRQoL), and the psychosocial factors that may influence this association among individuals with head and neck (H&N) cancer.
Method: A sample of 199 persons with H&N cancer using four OSGs completed an online questionnaire using six pre-validated measures for social network, self-efficacy, anxiety and depression, adjustment, empowerment and quality of life. In addition, socio-demographic as well as illness-related and OSGs-related information was collected.
Results: Participants who had better HRQoL had been using OSGs for a longer time than those who had worse HRQoL (B = 0.07, p < 0.05). Depression and adjustment were the only direct mediators in this association, whereas self-efficacy, anxiety and empowerment appeared as indirect mediators.
Conclusion: Participation in OSGs was found to be associated to better HRQoL either directly or indirectly through decreasing depression, anxiety and the negative adjustment behaviours and increasing self-efficacy and empowerment of the users. The study presented a potential model of pathways linking OSG use and HRQoL for those with H&N cancer. However, the model needs to be tested in future longitudinal studies and the associations proposed need to be explored in greater detail.
