Objective: To assess the predictive relationship between quality of life (QoL) domains with the subdomains of sense of coherence (SOC).
Methods: We measured the SOC and QoL of patients using the SOC-29 and the PROMIS-29/PROMIS global health measures, respectively. The SOC subdomains are comprehensibility, manageability and meaning. The measured PROMIS-29 QoL domains are physical function, anxiety, depression, fatigue, sleep disturbance, ability to participate in social roles and activities, pain interference and intensity while PROMIS global health are global physical health (GPH) and global mental health (GMH). Predictive relationships utilized random forest regression analysis based on variable importance.
Results: Our convenience sample consisted of 1980 responders (average age=40.72 years; 1494 females). Based on variable importance outcomes, the SOC subdomains were strong predictors for each other such that comprehensibility strongly predicted manageability and manageability strongly predicted meaning. The mental health domains (i.e., GMH, anxiety, depression) and age were also strong predictors for the SOC subdomains while the physical domains (i.e., physical function, pain interference) were the least predictive. Educational level predicted comprehensibility and meaning, while sleep disturbance predicted manageability.
Conclusion: The subdomains of SOC were strongly predictive for each other along with mental health QoL domains.
