Basic Information

• Recruitment Status: COMPLETED

Brief Summary

The objective of this study is to evaluate the effect of mindfulness-based cognitive therapy (MBCT) on physical symptoms attributed to chemical exposures, psychological distress, illness worry, quality of life, and illness perceptions in patients suffering from multiple chemical sensitivity (MCS). Furthermore, a secondary objective is to evaluate whether a possible symptom reduction is mediated by an increased level of mindfulness.

The primary hypothesis is that the self-reported severity of MCS symptoms and the degree to which chemical exposures causes symptoms and the impact on daily life will be significantly improved in the MBCT treatment group as compared to the control group.

Study Groups

MBCT intervention

Group Type: EXPERIMENTAL

Mindfulness-based Cognitive Therapy (MBCT)

Intervention Type: BEHAVIORAL

MBCT is partly based on the mindfulness-based stress reduction program (MBSR), developed by Jon Kabat-Zinn and colleagues, and partly on cognitive therapy for depression, the latter influence particularly expressed through the aspect of "decentering", meaning not accepting the content of thoughts as facts and not identifying with the thought. The MBCT programme in this study includes 2½ hours of training once a week for 9 weeks. In addition, participants are encouraged to practice at home for up to 45 min per day, 6 days a week during the entire course.

Control group

Group Type: NO_INTERVENTION
