Age‐stratified validation of the functional assessment of chronic illness therapy‐spiritual well‐being based on a large cohort of Danish cancer survivors

Measuring Spiritual Needs in a Secular Society: Validation and Clinimetric Properties of the Danish 20-Item Spiritual Needs Questionnaire

In secular cultures, such as Denmark, tools to measure spiritual needs are warranted to guide existential and spiritual care. We examined the clinimetric properties of the Danish version of the Spiritual Needs Questionnaire (DA-SpNQ-20) based on a digital survey in a test-retest setup. A convenience sample was reached via social media and student platforms. A total of 325 (148 for retest) respondents were included in the analysis. The sample was randomly split into two groups (A and B) and used for exploratory (EFA) and confirmatory factor analysis (CFA) by structural equation modeling, respectively. SpNQ dimensions had an internal consistency with Cronbach's alpha between 0.73 and 0.93. The four factors of the SpNQ were supported by both EFA and CFA as follows: religious needs, existential needs, inner peace needs, and generativity needs. The instrument showed good internal consistency, good test-retest reliability, and acceptable structural validity in the sample of relatively young and healthy persons.

Validation of the FACIT-Sp-12 in a Dutch cohort of patients with advanced cancer

OBJECTIVE

Although the Dutch Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being 12 Item Scale (FACIT-Sp-12) has been used in several Dutch studies, no study has assessed the measurement properties of the translation. The aim of this study was to perform an item-reduction analysis, confirmatory factor analysis (CFA), test of reliability, and test of convergent validity.

METHODS

From the baseline data of a cohort study on experienced quality of care and quality of life (eQuiPe study), 400 advanced cancer patients without missing values on any of the variables were selected. In addition to demographic and religious/spiritual characteristics, study measures included the FACIT-Sp-12 and the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-C30 (EORTC-QLQ-C30).

RESULTS

Item reduction analysis showed that Items 4 and 8 had low correlations to the total scale (<0.30). Items 6 and 7, and Items 9, 10, and 11 were highly correlated (>0.75). CFA indicated a good fit for a three-factor structure with Meaning, Peace and Faith, and good Cronbach's α coefficients for the total as well as the subscales (0.71-0.86). The removal of Items 4, 8, and 12 further improved the goodness of fit and Cronbach's α coefficients. Convergent validity was adequate with the EORTC-QLQ-C30.

CONCLUSION

Our analysis of the FACIT-Sp-12 revealed serious questions about three items and concerns about the Faith subscale. These problematic items deserve further attention so should be interpreted with care when using this scale. A future study could look into the items and test possible replacements.
