Thirty-two patients (29 women and 3 men) with stress-related ailments were recruited through the Community Health Care Centre in the city of Lidkoping, Sweden. The mean age was 47.75 years (SD = 8.30).
Pain Area Inventory (PAI; Bood, Sundequist, Kjellgren, Nordstrom, & Norlander, 2005) was used. The test consists of anatomical images of a human being on which the participants indicate their areas of pain with a color pen. The number of colored squares is calculated (total 1,666). Participants were randomized in equal numbers to either a control group or a flotation-REST group (twelve flotation sessions during six weeks). For more information on standard procedures see Bood et al.
A mixed ANOVA with PAI (before, after) as within-subjects factor and Group (control, flotation-REST) as between-subjects factor showed a significant interaction effect for Test and Group [F (1, 29) = 7.10, p = 0.012, Eta^sup 2^ = 0.20, power = 0.73] indicating no change in regard to pain for the control group (before: M = 46.59, SD = 41.68; after: M = 54.22, SD = 57.21) but an improvement for the flotation group (before: M = 60.94, SD = 57.96; after: M = 40. …
