“Don't need [therapy]! Not necessary, that's what we're for!”: Does content from fibromyalgia Facebook peer support groups emulate psychological flexibility principles?

The central finding was that content aligned with psychological inflexibility processes was posted consistently and was highly salient in all three groups, whereas content aligning with psychological flexibility processes occurred sporadically and elicited only brief, vague responses. The authors conclude that, for those whose goal is improved psychological flexibility, participation in these OPSGs should be approached cautiously and is not a substitute for professionally delivered ACT. Limitations include the observational methodology, which prevented collecting demographic data or directly assessing members' functioning or the impact of participation.
