Cross-Cultural Adaptation and Validation of the Constipation Scoring System for the Brazilian Population

Abstract

Background Beyond Rome IV Criteria, the assessment of functional constipation in clinical practice can also be obtained by the Constipation Scoring System (CSS). By accessing the CSS, health professionals are able to measure this dysfunction, guiding initial therapeutic approach and post-treatment response. In addition, the CSS enables the standardization of results concerning functional constipation research. Objective To promote translation, cross-cultural adaptation and validation of the CSS for the Brazilian population. Methods To attain the score in Portuguese, the adaptation was accomplished in four steps (translation, back translation, application and adjustments). Afterward, the validation and adaptation to the Brazilian population was performed through test-retest. Results For adults, the convergent validity of the Brazilian version of the CSS showed a significant correlation to the Rome IV Criteria evinced by the positive Spearman correlation (r2) of 0.816 (P<0.001). Between the test-retest responses, the translated version of the score had a Cronbach’s Alpha of 0.972. A high level of internal consistency was also obtained when each item of the questionnaire was assessed separately, revealing an adequate internal reliability Conclusion The CSS was well adapted and accepted by the Brazilian population, demonstrating the linguistic and psychometric validity of this Portuguese version of the score.

Constipation in Women with High-Grade Intraepithelial Neoplasia and Cervical Cancer: Does the Extent of Cervical Lesion Invasion Influence the Severity of Constipation and Compromise Quality of Life?

“…15 The Constipation Scoring System (CSS) adapted, and validated for the Portuguese language was used to assess constipation intensity. 16 A self-report questionnaire was used in addition to the aforementioned instruments to collect information about demographic characteristics (age), education, painkiller use, and childbirth (number of pregnancies and type of birth). The Visual Analogue Scale (VAS) was used to assess the impact of constipation on women's daily lives.…”

Constipation. An Old New Problem

“…Taniguchi et al bring the proposal of a clinical score, adapted and aimed at the Brazilian population, aiming to create an environment to measure and quantify changes in intestinal dysfunction and serve as an initial guide for the choice of the best therapy (9) . Perhaps one of the most important aspects of this work is to be adapted specifically to the Brazilian population because, as stated above, the diagnostic criteria are greatly influenced by the environment, habits, diet, and language comprehension, among other aspects.…”
