Psychometric properties of food frequency questionnaires used in dentistry: a systematic review

Abstract

The objective of this systematic review was to analyze the quality of the food frequency instruments/scales used in dentistry while considering their psychometric properties. The databases consulted were PubMed (07/08/2020), Scopus (08/27/2020), Web of Science (08/27/2020), Cumulative Index to Nursing and Allied Health Literature (CINAHL) and Dentistry and Oral Sciences Source (via EBSCO) (28/ 08/2020 ), LILACS and BBO (25/08/2020), Gray Literature: Proquest (01/10/2020), Capes Theses Bank (01/10/2020), Brazilian Digital Library of Theses and Dissertations (01/01 10/2020), Google Scholar (02/10/2020), and proceedings of the International Association for Dental Research (IADR) (10/10/2020). All data bases were updated on 12.12.2022. Articles were initially selected by reading the 6421 titles and 13 abstracts selected, followed by reading the 8 articles included for full text reading to confirm the eligibility criteria, with the aid of Rayyan software. databases the construction and/or validation of instruments/scales for assessing food consumption for use in dentistry (in clinical contexts and/or epidemiological studies), with or without assessment of their psychometric properties, were included. Review studies, letters to editors, and research protocols were excluded. Risk of bias assessment was performed according to the COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) checklist. The extracted data were: author, country, instrument language, sample, assessment instrument, instrument structure, type of food, instruments compared with the clinical condition, adaptation of an existing instrument, and psychometric properties evaluated. The selection, risk of bias analysis, and data extraction processes were performed by two independent evaluators. Seven studies were identified. The instruments available in the literature were in English, Japanese, Creole and Malay. Only one study performed translation and cross-cultural validation of an instrument, whereas the others were construction studies. One study did not assess psychometric properties. Regarding the quality assessment and general classification of the studies by the COSMIN checklist, all were considered “inadequate,” with reliability (test-retest) being the most validated psychometric property; only one study carried out the validation of all psychometric properties measured in COSMIN. Regarding the quality of the instruments presented, all the studies were classified as “inadequate” in the general assessment. Advances are needed in the validation process.
