Measuring Spiritual Well-being using a numerical rating scale: Additional evidence of the validity of the Well-being Numerical Rating Scales (WB-NRSs)

The Well-being Numerical Rating Scales (WB-NRSs) can be used to assess rapidly and accurately different types of well-being. However, the spiritual well-being scale showed slightly weaker psychometric properties. This study aimed to further investigate its suitability in measuring spiritual well-being. Participants (N = 270, age: M = 32.98; SD = 15.64; 67% females) were administered a questionnaire including spiritual well-being, gratitude, compassionate love, and personality traits measures. A network analysis (based on correlations) was used to display graphically the pattern of relationships among the measured constructs (i.e. the nomological net). Results provided evidence that the scale measures spiritual well-being as defined in the literature, that is, a component distinct from faith and compassionate love, but connected to meaning in life, quality of relationships, personality traits, and gratitude. These findings confirm the WB-NRSs is a psychometrically sound and easy-to-use tool with clear benefits for both research and clinical assessment.
