Factor structure of the spiritual needs questionnaire (SpNQ) in persons with chronic diseases, elderly and healthy individuals

Abstract

The Spiritual Needs Questionnaire (SpNQ) is an established measure of psychosocial, existential and spiritual needs. Its 4-factor structure has been primarily validated in persons with chronic diseases, but until now has not been done in elderly and stressed healthy populations. Therefore, we tested the factor structure of the SpNQ in: (1) persons with chronic diseases (n = 627); (2) persons with chronic disease plus elderly (n = 940); (3) healthy persons (i.e., adults and elderly) (n = 1468); and (4) chronically ill, elderly, and healthy persons together (n = 2095). The suggested structure was then validated using structured equation modelling (SEM). The 4-factor structure of the 20-item SpNQ (SpNQ-20) was confirmed, differentiating Religious Needs, Existential Needs, Inner Peace Needs, and Giving/Generativity Needs. The psychometric properties of the measure indicated (CFI = 0.96, TLI = 0.95, RMSEA = 0.04 and SRMR = 0.03), with good reliability indices (Cronbach’s alpha varying from 0.71 to 0.81). This latest version of the SpNQ provides researchers with a reliable and valid instrument that can now be used in comparative studies. Cultural and religious differences can be addressed using their different language versions, assuming the SpNQ’s structure is maintained.
