Severity of temporomandibular disorders in women: validity and reliability of the Fonseca Anamnestic Index

Abstract

The aim of this study was to assess the validity and reliability of the Fonseca Anamnestic Index (IAF), used to assess the severity of temporomandibular disorders, applied to Brazilian women. We used a probabilistic sampling design. The participants were 700 women over 18 years of age, living in the city of Araraquara (SP). The IAF questionnaire was applied by telephone interviews. We conducted Confirmatory Factor Analysis (CFA) using Chi-Square Over Degrees of Freedom (χ 2 /df), Comparative Fit Index (CFI), Tucker-Lewis Index (TLI), and Root Mean Square Error of Approximation (RMSEA) as goodness of fit indices. We calculated the convergent validity, the average variance extracted (AVE) and the composite reliability (CR). Internal consistency was assessed by Cronbach's alpha coefficient (a).The factorial weights of questions 8 and 10 were below the adequate values. Thus, we refined the original model and these questions were excluded. The resulting factorial model showed appropriate goodness of fit to the sample (χ 2 /df = 3.319, CFI = 0.978, TLI = 0.967, RMSEA = 0.058). The convergent validity (AVE = 0.513, CR = 0.878) and internal consistency (a = 0.745) were adequate. The reduced IAF version showed adequate validity and reliability in a sample of Brazilian women.

Temporomandibular disorders in elderly individuals: the influence of institutionalization and sociodemographic factors

“…These inequalities have been increasing worldwide, as is the elderly population (7,19,20) . Martins et al (21) , in a study performed in São Paulo (Brazil), observed the relationship between occurrence of TMD and economic class, educational level, age and gender, but found a (3,5,14) . This study found differences in the prevalence of TMD among different educational levels.…”

“…The Fonseca Anamnestic Index (IAF) was used to detect TMD (11) . The IAF was chosen because it is available in Portuguese; it's a valid tool for characterization of TMD symptoms; it's recommended for use in the public health service for screening of TMD; and due to its simplicity, rapidity and low cost (11)(12)(13)(14) . The index consists of 10 questions that can be answered with "Yes", "Sometimes" and "No", associated with scores 10 (ten), 5 (five) and 0 (zero), respectively.…”

“…The sum of these scores categorized TMD as: absent, if the score was below 20; and present, if the score was above 20. Where TMD was present, it was classified as: mild, if the score was below 45; moderate, if the score was below 70; and severe, if the score was above 70 (11)(12)(13)(14) . The data collected was statistically analyzed using the program R version 2.9.0 (Vienna, Austria).…”

“…The FAI [14] was used to evaluate and to characterize the TMD signs and symptoms. It is also used to classify individuals according to TMD severity (mild, moderate, severe and no TMD).…”

“…The FAI would serve as a preliminary TMD screening tool. The use of FAI is easily used by either general practitioners or epidemiologists [13] [14].…”
