Development of a scale to assess the meditation experience

This paper describes the initial development of a scale to assess the effects of meditation. The scale consists of two sections: Experiences During Meditation (EOM-DM) and Effects of Meditation in Everyday Life (EOM-EL). Scale evaluation on 236 participants involved factor analysis, reliability and validity analysis. The EOM-DM scale had five subscales: Cognitive effects, Emotional effects, Mystical experiences, Relaxation and Physical discomfort. The physical, emotional, expanded consciousness and cognitive item groups of the EOM-EL were analysed separately. Each scale had a single factor structure whereas analysis of the EOM-EL-cognitive scale identified four factors: Social relations, Cognitive ability, Non-judgemental acceptance and Behaviours and habits. Construct validity was explored by assessing correlations with existing measures: Mindful Attention Awareness Scale, FACIT Spiritual wellbeing subscale and POMS-Short Form. Although further development is required, the scale showed adequate psychometric properties and may be useful for clinicians and researchers to improve understanding of the effects of meditation practices.
