OBJECTIVES: (1) To investigate the effects of a 6-week intervention of guided imagery on pain level, functional status, and self-efficacy in persons with fibromyalgia (FM); and (2) to explore the dose-response effect of imagery use on outcomes.
DESIGN: Longitudinal, prospective, two-group, randomized, controlled clinical trial.
SETTING AND SUBJECTS: The sample included 48 persons with FM recruited from physicians' offices and clinics in the mid-Atlantic region.
INTERVENTION: Participants randomized to Guided Imagery (GI) plus Usual Care intervention group received a set of three audiotaped guided imagery scripts and were instructed to use at least one tape daily for 6 weeks and report weekly frequency of use (dosage). Participants assigned to the Usual Care alone group submitted weekly report forms on usual care.
MEASURES: All participants completed the Short-Form McGill Pain Questionnaire (SF-MPQ), Arthritis Self- Efficacy Scale (ASES), and Fibromyalgia Impact Questionnaire (FIQ), at baseline, 6, and 10 weeks, and submitted frequency of use report forms.
RESULTS: FIQ scores decreased over time in the GI group compared to the Usual Care group (p = 0.03). Ratings of self-efficacy for managing pain (p = 0.03) and other symptoms of FM also increased significantly over time (p =<0.01) in the GI group compared to the Usual Care group. Pain as measured by the SF-MPQ did not change over time or by group. Imagery dosage was not significant.
CONCLUSIONS: This study demonstrated the effectiveness of guided imagery in improving functional status and sense of self-efficacy for managing pain and other symptoms of FM. However, participants' reports of pain did not change. Further studies investigating the effects of mind-body interventions as adjunctive self-care modalities are warranted in the fibromyalgia patient population.
