Assessing Religious Commitment in a Multicultural Inpatient Setting: A Psychometric Evaluation of the 10-item Belief into Action Scale.

Religious and spiritual (R/S) issues impact medical decision-making, particularly among highly R/S populations, for whom existing measures have limitations in identifying levels of R/S commitment. The Belief into Action (BIAc) scale was designed for this purpose and was never tested among hospitalized patients. We interviewed 152 patients (51% men) with a mean age of 48.9 years (SD = 15.2), having either cancer (27%), cardiovascular (26%), rheumatic (21%), or other diseases (26%). Cronbach alpha was .82 and a 3-factor structure (subjective, social, and private religious commitment) was the most robust. Results suggest the BIAc has adequate convergent, divergent, and incremental validity compared to other well-established questionnaires and is appropriate for the inpatient setting.
