SCHIMITT, Regina Lopes et al. Cross-cultural adaptation of the Brazilian version of the Social Rhythm Metric-17 (SRM-17) for the population of Angola. Rev. psiquiatr. Rio Gd. Sul [online]. 2011, vol.33, n.1, pp. 28-34. Epub Apr 29, 2011. ISSN 0101-8108. http://dx.doi.org/10.1590/S0101-81082011005000008.
INTRODUCTION: Social rhythm is a concept that correlates social Zeitgebers (synchronizers) with endogenous markers of time, and can be assessed with the Social Rhythm Metric-17 (SRM-17). The aim of this study was to adapt the Brazilian version of the SRM-17 to Angolan Portuguese, comparing the two scales in samples that speak the same language but have cultural differences. METHODS: The Brazilian version of the SRM-17 was assessed by 10 Angolan students who analyzed the intelligibility of the 15 sentences contained in the instrument using a 10-cm visual analog scale and proposed changes to the text. Results were reviewed for the generation of a final Angolan version, followed by a reading test and the production of a final report. RESULTS: The final Angolan version of SRM-17 maintained an equivalence of items in relation to the Brazilian Portuguese version. The version assessed by the students showed a satisfactory degree of intelligibility and semantic equivalence in most items. However, some items presented intelligibility results below the mean total scores of the scale (8.38 ± 1.0). CONCLUSION: Although the populations of Brazil and Angola speak the same language, significant cultural differences were found between the two countries. This paper presents an instrument to assess social rhythm adapted to the Angolan culture. The cross-cultural adaptation process herein described should be continued by validating the final version of the instrument in a larger sample and by assessing operational, functional, and measure equivalence.
