The present study developed and evaluated the psychometric properties of the Mindfulness-based Self Efficacy Scale (MSES), which aims to measure skills arising from mindfulness-based practices before, during and after clinical interventions. This and previous studies have demonstrated that the MSES has high internal consistency (Chronbach Alpha = .86) and correlates well with other measures of mindfulness (KIMS, MAAS and FMI). 

This study consisted of 521 participants from the general community and the University of Tasmania. Of these, 100 participants went on to participate in the retest phase of the study.  Materials included the MSES, the Depression, Anxiety and Stress Scale (DASS21) and the Five Facet Mindfulness Questionnaire (FFMQ), which is thought to measure the construct of mindfulness.  Results of an exploratory factor analysis found support for a six-factor model in a 22-item scale.  These factors were Emotion Regulation, Equanimity, Social Skills, Distress Tolerance, Taking Responsibility and Interpersonal Effectiveness.  All factors demonstrated good test-retest reliability (r = .88) and construct validity by correlating with several constructs in ways that were consistent with theory. The MSES is able to differentiate well clinical from non-clinical populations, both statistically (p < .01) and clinically (g = .79). Norms for clinical and community groups are currently being collected. The MSES can be used online which provides automated scoring, norms comparisons and graphs, all exportable to a spreadsheet as .csv files.
