PURPOSE: To determine relationships between the Brief Multidimensional Measure of Religiousness/Spirituality (BMMRS; i.e., positive/negative spirituality, forgiveness, religious practices, positive/negative congregational support) and physical and mental health (Medical Outcomes Scale-Short Form 36; SF-36) for individuals with chronic disabilities. RESEARCH METHOD: A cross-sectional analysis of 118 individuals evaluated in outpatient settings, including 61 with traumatic brain injury (TBI), 32 with cerebral vascular accidents (CVA), and 25 with spinal cord injury (SCI). RESULTS: Three of 6 BMMRS factor scores (i.e., positive spiritual experience, forgiveness, negative spiritual experience) were significantly correlated with the SF-36 General Health Perception (GHP) scale, and only 1 of 6 BMMRS factor scores (i.e., negative spiritual experience) was significantly and negatively correlated with the SF-36 General Mental Health (GMH) scale. BMMRS scales did not significantly predict either physical or mental health in hierarchical multiple regressions. CONCLUSIONS: Positive spiritual experiences and willingness to forgive are related to better physical health, while negative spiritual experiences are related to worse physical and mental health for individuals with chronic disabilities. Future research using the BMMRS will benefit from using a 6-factor model that evaluates positive/negative spiritual experiences, religious practices, and positive/negative congregational support. Interventions to accentuate positive spiritual beliefs (e.g., forgiveness protocols, etc.) and reduce negative spiritual beliefs for individuals with chronic disabilities are suggested.
