RESUMO:

Aging causes changes in the stomatognathic system which influence the masticatory function, and promote disorders that may affect the eating process, oral phase of swallowing, and nutrition status, compromising the older adult population quality of life. Thus, this study aims to construct and validate the instrument for screening for masticatory disorders in older adults (SMDOA). This is a non-randomized and sectional validation study, and the method followed the traditional guidelines of the Standards for Educational and Psychological Testing. The study population consisted of older adults of both genders, aged 60 or over, recruited by convenience. In the first stage of the study, the validity evidence based on the content was obtained through a panel of four experts who defined the construct and content of the instrument and considered the evaluation of 28-experts-committee in relation to the representativeness and relevance of the items of the construct on the first version of SMDOA with 16 questions. The analysis performed through the Content Validity Index by Items (CVI-I) and the Content Validity Index (CVI) was satisfactory. Only one question has been deleted. The second version of SMDOA with 15 items was applied to the target population of 40 older adults to obtain validity evidence based on response processes. After quantitative and qualitative analysis of the answers, it was found that the instrument was well evaluated by the older adults requiring minor morphosyntax adjustments. The third version of RAMI, still with 15 questions, was applied to 295 older adults to obtain validity evidence based on the internal structure. Confirmatory factor analysis was performed to adjust the model. The SMDOA was adjusted in its internal structure, resulting in the model of 9 questions in two factors, masticatory function and perception (c2 = 48,7, p = 0,004, c2/gl =1,76, RMSEA = 0,05, WRMR = 0,75, CFI = 0,98 e TLI = 0,98). The fourth version of SMDOA was submitted to obtaining validity evidence based on relation to other variables in a population of 196 older adults and considered the analysis of Spearman's correlation coefficient (r). The convergent validity was confirmed by the moderate correlation between SMDOA results and four validated instruments with outcomes related to temporomandibular disorders (r= 0,330; p<0,001), hyposalivation (r= 0,442; p<0,001), oropharyngeal dysphagia (r= 0,456; p<0,001) and oral health (r= -0,681; p<0,001). Discriminant validity was confirmed by the weak correlation between SMDOA and a validated self-esteem scale (r= -0,269; p<0,001). Reliability analysis was performed by applying the test-retest in 124 elderly, through weighted Kappa, intraclass correlation coefficient (ICC), standard error of measurement (SEM), smallest real difference (SRD) and Cronbach's alpha. A significance level of 5% was considered. The 9-question SMDOA has good reliability indices (ICC = 0,87, IC 0,82-0,91, p <0,001; SEM = 1,90; SRD = 5,25) and high internal consistency (a = 0,93). SMDOA presented valid and reliable responses to identify masticatory disorders in community-dwelling older adults.
