The Self-Regulation Assessment (SeRA) questionnaire: development and exploratory analyses of a new patient-reported outcome measure for rehabilitation

Purpose To develop and explore underlying dimensions of the Self-Regulation Assessment (SeRA) and psychometric features of potential components. Further, to identify associations between the SeRA and disability-management self-efficacy, type of diagnosis, and type of rehabilitation. Materials and methods Based on a previously developed model of self-regulation, expert and patient opinions, and cognitive interviews, a list of 22 items on self-regulation (the SeRA) was constructed. The SeRA was included in a cross-sectional survey among a multi-diagnostic group of 563 former rehabilitation patients. Exploratory analyses were conducted. Results Respondents had a mean age of 56.5 (SD 12.7) years. The largest diagnostic groups were chronic pain disorder and brain injury. Four components were found within the SeRA, labelled as "insight into own health condition," "insight into own capabilities," "apply self-regulation," and "organization of help." Cronbach's alpha was high (total scale: 0.93, subscales: range 0.85-0.89). Only scores on the first subscale showed a ceiling effect. Subscale three showed the highest correlation with a self-efficacy measure. Small differences in SeRA total scores (range 71.6-78.1) were found between different diagnostic groups. Conclusion The SeRA is a new self-regulation measure with four subscales. Further research is needed to establish the validity and reliability of the SeRA.
