Investigating the psychometric properties of the Five Facet Mindfulness Questionnaire- Short Form.

OBJECTIVES: The Five Facet Mindfulness Questionnaire - Short Form (FFMQ-15) measures the tendency to be mindful and is proposed as an alternative to the original 39-item version. This study examines the psychometric properties of the FFMQ-15 in a clinical sample to provide further support for a short-form version. METHOD: Participants (N = 244; M_age = 29.68) included in the study completed the FFMQ-39 and FFMQ-15, the Brief Experiential Avoidance Questionnaire (BEAQ), and the Adult ADHD Self-Report Scale - Part A (ASRS). A confirmatory factor analysis (CFA) examined the structure of the FFMQ-15. RESULTS: The FFMQ-15 demonstrates moderate to excellent internal consistency. The FFMQ-15 showed significant correlations in predicted directions with the FFMQ-39, the BEAQ, and the ASRS. The CFA supports a four-factor hierarchical model, excluding the Observing subscale. CONCLUSION: Results indicate reasonable psychometric properties of the FFMQ-15 but suggest further examination of the Observing subscale.
