Mindfulness Advancement Questionnaire (Polish adaptation and validation)

Summary/Abstract: This paper aimed to adaptation of the MINDSENS questionnaire used to measure of advancement in mindfulness among meditators and nonmeditators. The research sample consisted of two groups of people: 1) with meditation experience (N = 656: 74.6% including Christian meditation – 33.5%; mindfulness – 24.4%; concentration techniques such as yoga and transcendental meditation – 16.2%), and 2) without meditation experience (N = 226: 25.4%) controlled for length and frequency of meditation practice and disorders. The validation procedure showed that the Polish adaptation of MINDSENS i.e., the Mindfulness Advancement Questionnaire (Observing, Non-Reactivity, and Decentration) demonstrated the solid factor structure (3-factor model with bifactor), high factor loadings, good composite (0.74 ≤ CR ≤ 0.93) and construct reliability (0.82 ≤ H ≤ 0.93), fine absolute stability (0.76 ≤ rtt ≤ 0.82), and solid external validity. Thus, the validated questionnaire can be used as valuable measure of mindfulness advancement in meditators, clinical and nonclinical populations, aged 15–72.
