Assessing MB-Spirit for Psychological Well-being

The meaning and peace subscale of the widely used and well-validated FACIT-SP-non-illness (Functional assessment of chronic illness therapy spiritual wellbeing - non illness) is our primary outcome metric. It has very good reliability (alpha=.81) and has high discriminate validity.

Duke University Religion Index (DUREL) is a five-item measure to assess religiosity by examining three key dimensions: organizational religious activity (e.g., attending services), non-organizational religious activity (e.g., private prayer), and intrinsic religiosity (e.g., personal religious commitment and its influence on life). The overall scale has high test-retest reliability (intra-class correlation = 0.91), high internal consistence (Cronbach's alpha's = 0.78-0.91), high convergent validity with other measures of religiosity (r's = 0.71-0.86).

Brief Signature Strengths Use Scale (BSSUS) measures the extent to which participants recognize and use their signature character strengths. Five items are scored on a 7-point Likert scale, ranging from ranging from Strongly disagree to Very strongly agree. Higher scores indicate higher strength use.

The Metacognitive Processes of Decentering Scale (MPoD-t) is a self-report scale developed to measure the ability to decenter, or separate one's sense of self from internal experiences, by assessing three core metacognitive processes: meta-awareness, (dis)identification with internal states, and (non)reactivity to thought content. The MPoD-t scales are used to study decentering, its role in mental health, and its potential as a therapeutic mechanism in mindfulness-based interventions

The 29-item PROMIS-29 contains short assessments of eight core health domains including: anxiety, depression, physical function, sleep disturbance, pain interference and pain intensity, fatigue, and ability to participate in social roles and activities. Cronbach's α reliability for all domains range from 0.77 to 0.98 and scores remained stable over 18 months132 All domains use a 7-day recall period, except for PF and SRAA.
