Spirituality Among Alzheimer's Caregivers: Psychometric Reevaluation of the Intrinsic Spirituality Scale

ABSTRACT

The purpose of this study was to reevaluate psychometric properties of the Intrinsic Spirituality Scale (ISS) and to compare its results to the original psychometric report. Attendees of Alzheimer's caregiver support groups constituted the sample, relevant to this measure given their traditional, frequent use of spirituality as a coping resource. Data were randomly split for factor and reliability analyses (N ₁= 152) and validity analysis (N ₂= 152). Factor analysis on the ISS loaded all items on a single dimension of spirituality. Reliability was strong. Convergent validity was suggested via significant correlations with prayer measures. Enhanced with the original findings, these results lend credibility to the ISS as a viable spiritual assessment tool. The ISS offers social service professionals a valuable tool for assessing spirituality that is inclusive of individuals whose spirituality is nontheistic or for whom spirituality exists independently from, or outside of, organized religious structures. Future analyses with additional populations may broaden the ISS applicability among persons with diverse demographic and spiritual backgrounds.
