Four themes of self-regulation were identified by former patients and rehabilitation physicians in a previous study. Based on these themes a measure for self-regulation, the Self-Regulation Assessment (SeRA), was developed. This study aimed to establish the content validity of the SeRA in a multicultural and multi-diagnostic post-rehabilitation population. Methods: COSMIN methodology was applied. First, cognitive interviews were held with eight former rehabilitation patients. Feedback was obtained on relevance, comprehensibility and comprehensiveness of the items. Items with problems were revised. Then, a second series of cognitive interviews was held with sixteen former rehabilitation patients with non-Western migration backgrounds. Again feedback was obtained on relevance, comprehensibility and comprehensiveness of the items. Results: The first series of cognitive interviews revealed good comprehensiveness, but also comprehensibility or relevance problems with twelve of the 25 items. These items were revised or deleted. Two missing concepts were identified and these were added. There was no need to revise the items based on the results of the second series of cognitive interviews. Conclusion: The final version of the SeRA demonstrated content validity for the studied population. The measure is ready for psychometric analyses in subsequent validation studies.
