The Meaning and Purpose Scales (MAPS): development and multi-study validation of short measures of meaningfulness, crisis of meaning, and sources of purpose

Table 5 Scale means and standard deviations, number of items, response range, skewness, range of corrected item-total correlations, and internal consistencies (McDonald’s Omega and Cronbach’s alpha) with 95% CIs
