Abstract
Aim To develop and validate the Spirituality Instrument 27 (SpI-27©) in individuals with chronic illness (n = 249). Background A need for a rigorously developed spirituality instrument that can be used with people who are religious and non-religious was identified. Methods The initial 46-item instrument was developed from a concept analysis, a review of theoretical and empirical literature, and an appraisal of instruments measuring spirituality. Content validity was established with user focus groups and an expert panel review. A pilot study evaluated the online mode of administration and a descriptive correlational design assessed the reliability and validity of the instrument. Results Results of exploratory factor analysis concluded a five-factor solution with 27 items: Connectedness with Others, Self-Transcendence, Self-Cognisance, Conservationism, and Connectedness with a Higher Power. Cronbach's alpha coefficients ranged from 0.823 to 0.911 for the five factors, and 0.904 for the overall scale. Paired t-tests, intra-class correlations, and weighted kappa values supported the temporal stability of the instrument. A significant and positive correlation was found between the SpI-27© and the Spirituality Index of Well-Being (p < 0.01), supporting convergent validity. Conclusions Findings support the validity and reliability of the SpI-27©, which was developed with patient input and is underpinned by theoretical and empirical literature. The SpI-27© should be validated for use with other samples. The conceptual framework that guided the study can be used to enhance healthcare professionals' understanding of spirituality and its core dimensions.
