Evidence for the Brief Mysticism Scale: Psychometric Properties, and Moderation and Mediation Effects in Predicting Spiritual Self-Identification

How are mystical experiences related to self-rated spirituality? Is the recently developed short 8-item version of Hood’s Mysticism Scale an efficient measurement? The current study expands evidence for both questions using N = 1,582 American and 1,492 German samples measured in three waves, average 4 5 years apart. Results show that brief M-Scale has good psychometric property evidenced by 1) measurement invariance across time, 2) test–retest reliability. further demonstrate 3) moderates effect religiosity on spirituality, 4) mediates prediction spirituality over time. We conclude can be used as a measure self-attributed when questionnaire length is issue.
