Aim: The overall aim of this thesis was to study prognostic factors for prolonged disability in back pain in the general population and physiotherapists’ screening for prolonged disability, applying a social cognitive learning perspective. Methods and results: Studies I and II were based on a survey in the general population in Sweden. Study I included 1024 individuals aged 20-50 years, reporting non-specific back pain. Four groups (n = 100, 215, 172 and 537) based on duration and recurrence of back pain were formed and compared. After controlling for pain intensity, catastrophising and expectations of future pain were positively correlated to pain duration. Perceived social support was negatively correlated to pain duration. Study II was longitudinal over 12 months and analysed one group reporting first-episode back pain (n = 77), and one group reporting long-term back pain (n = 302). Future pain intensity and disability were predicted by initial levels of pain and disability and pain-related cognitions in both groups. Study III examined the inter-rater reliability of a research protocol for assessment of physiotherapists’ telephone screening for prolonged disability. The results demonstrated sufficient inter-rater reliability. Study IV evaluated the effect of a tailored skills training intervention on physiotherapists’ screening for prolonged disability in back pain. Four physiotherapists in primary care participated in four quasi-experimental single-subject studies. Effects were seen in all participants, with increased screening of prognostic factors and less time spent on detailed discussions about back pain. Conclusions: The identification of mainly cognitive explanatory variables indicates the relevance of a social cognitive perspective of back pain-related disability (studies I and II). Physiotherapists’ telephone screening for prolonged disability in back can be reliably assessed (study III). It is suggested that interventions based on social cognitive theory are effective in producing change in specified clinical behaviours in physiotherapists (study IV).
