ObjectiveTo assess the influence of an educational intervention in reducing «fear-avoidance» (FA) and «pain catastrophising» (CAT) in a population with unspecific chronic low back pain (UCLBP), attending physiotherapy in Primary Health Care. A pragmatic quasi-experimental study was conducted in Health Centres of a Costa del Sol Health District.DesignQuasi-experimental study.SettingPrimary Health Care physiotherapy Back Schools in Health Centres of a Costa del Sol Health District.ParticipantsThe selection criteria were: UCLBP; 18-65years; understanding of the Spanish language; absence of parallel educational interventions; absence of red flags; not showing cognitive impairment or fibromyalgia; absence of thoracic-lumbar surgery, and exercise tolerance.InterventionsThe control group received the usual Back Schools program. The experimental group also received a written document for home reading, plus the subsequent sharing, clarifying doubts, and beliefs and goals restructuring during the development of the sessions. Both interventions lasted about 280minutes (7 sessions×40min).ResultsThe main variables included FA and CAT. Pain and disability were also assessed. Some «demographic» and «related disorder» variables were considered in the analysis. Statistically significant differences were observed in the experimental group versus control, in the variation of FA -14 (-25.5; 0) vs -4 (-13; 0) (P=.009), and CAT -9 (-18; -4) vs -4,5 (-8.25; 0) (P=.000), were observed. Also differences in disability (P=.046), but not in pain (P=.280).ConclusionsThese results should be considered in light of possible limits imposed by the study. Its pragmatic nature would allow a potential transfer to usual care.Copyright © 2015 Elsevier España, S.L.U. All rights reserved.
