Psychometric properties and validation of the Swedish Five Facet Mindfulness Questionnaire in a clinical and non-clinical sample among meditators and non-meditators.

Over a period of 15 years several attempts to conceptualize mindfulness have been presented and revised, but there is still no clear or agreed-upon definition. The use of mindfulness-based interventions has increased in clinical and research settings the last couple of years, including in Sweden. As a clinician it is crucial to know if a treatment works through the theoretically postulated mechanisms of change. Mindfulness is a concept that is difficult to measure. The overall aim of the current project was to examine the psychometric properties of the Swedish version of the Five Facet Mindfulness Questionnaire (FFMQ_SWE) using three different studies. To test the construct validity of the FFMQ_SWE a hierarchal confirmatory factor analysis was performed in a meditating non-clinical sample, to examine if all the five facets would load on an overall mindfulness construct. Psychometric properties of the instrument were examined in a non-clinical and a clinical sample, and discriminative relationships with other variables were analysed. The convergent validity was examined by analysing the correlations between FFMQ_SWE and Hospital Anxiety and Depression Scale, Sense of Coherence and Difficulties in Emotion Regulation Scale. Test-retest reliability was tested by distributing FFMQ_SWE at two occasions. The hierarchal confirmatory factor analysis showed good fit in a population of meditators. The FFMQ_SWE showed good convergent validity and test-retest reliability in both clinical and non-clinical populations. In sum, the Swedish version of the FFMQ showed good psychometric properties and can be a useful instrument as an evaluation of treatment effects in both health care settings and research settings.

Mindfulness-based cognitive therapy is effective as relapse prevention for patients with recurrent depression in Scandinavian primary health care.

This study examined the effectiveness of mindfulness-based cognitive therapy (MBCT) in primary care for patients with recurrent depression (major depressive disorder: MDD). According to the World Health Organization (WHO), MDD is now the leading cause of disease burden in middle- and high-income countries. Patients (N = 45) with three or more previous depressive episodes were recruited to participate in MBCT as a preventative intervention. Using a benchmarking approach, outcome data was compared with data from a recent efficacy study. The methodology is a rigorous approach to assessing effectiveness when evidence-based UK protocols are transferred into the existing Scandinavian service delivery. Additionally, a person-centred methodological approach was used to assess clinical significance on the Reliable Change Index (RCI). The analysis revealed comparable or larger effects from pre-test to post-test in reduced psychiatric symptoms, increased quality of life and level of mindfulness, and the effects were maintained over 14 months. Analysis of the relapse rate in the current study (16%) compared to the TAU in the efficacy study (68%) yielded an h value of 0.78, a moderate effect size. Only 13% dropped out of the treatment. According to the RCI findings, 65% to 67% of participants in the clinical group improved, no individual worsened, and women showed a significantly greater improvement of depression and anxiety than men. Therapeutic alliance and motivation had no impact on the outcome. The overall result suggests that MBCT can be implemented successfully in Scandinavian primary health care as a preventive intervention for patients with recurrent depression.
