The Relationship Between Acceptance, Biopsychosocial Factors, and Quality of Life: A Structural Equation Model

Disability acceptance is one of the most significant constructs in the psychosocial adaptation process. Although prior research has examined the relationship among different biopsychosocial factors, disability acceptance, and quality of life (QoL), limited study focused on entering a series of biopsychosocial factors simultaneously into analysis to reflect live experience of individuals with disabilities. This study aimed to examine the role of acceptance regarding the relationship between a series of biopsychosocial factors (i.e., general health, physical functioning, pain, anxiety, depression, stress, loneliness, stigma, sense of community, and neighborhood problems) and QoL based on Livneh’s psychosocial adaptation model to inform psychosocial interventions. A total of 430 participants with disabilities completed an online survey consisting of instruments measuring target variables. Exploratory and confirmatory factor analyses indicated a three-factor structure for selected biopsychosocial factors (i.e., psychological difficulties, physical status, and community issues). Structural equation modeling results showed that the proposed model indicated a fair model fit after respecification. Effect analyses showed that disability acceptance directly affected QoL and partially mediated the relationship between physical status and QoL and psychological difficulties and QoL. In addition, loneliness has been found to significantly and directly predict QoL in the respecified model. The model demonstrated that disability acceptance and loneliness have a significant impact on QoL.
