0300/2024 - Processo de Validação e Caraterísticas Metodológicas de Escalas de Percepção da Insegurança Alimentar: uma Revisão de Escopo Validation Process and Methodological Characteristics of Food Insecurity Perception Scales: a Scope Review
Objetivou-se nesta revisão de escopo identificar o processo de validação e as caraterísticas metodológicas das escalas de percepção de insegurança alimentar validadas em diferentes partes do mundo. Realizou-se busca na PubMed, Embase, Scielo, Mediline, Lilacs e Google Acadêmico, além da literatura cinzenta. A pré-seleção dos estudos deu-se pela leitura dos títulos e resumos, seguida pela leitura na íntegra. Dos 828 estudos identificados, selecionou-se 19 referentes a 21 escalas dos países: Colômbia; Tanzânia; Líbano; Nova Zelândia; Estados Unidos; Equador; Sir Lanka; Brasil; Guatemala; República Dominicana; Haiti; Costa Rica; Venezuela; México; Bolívia; Burkina Faso e Filipinas, bem como, a Escala Latino-americana e Caribenha (ELCSA) e da FAO. A Colômbia e Equador apresentaram duas escalas validadas. As escalas variaram em relação ao ano de validação (2000 à 2020), tempo de referência (últimos 3 à 12 meses), número de questões (7 à 18) e tipos de domicílios (urbanos e rurais). Os processos de validação envolveram fases qualitativas e quantitativas. A validação interna foi realizada pelo coeficiente Alfa de Cronbach e o modelo Rasch; e a externa por associação e/ou correlação com variáveis socioeconômicas e de consumo alimentar. Assim, as escalas identificadas apresentaram processos de validação e caraterísticas metodológicas distintas, sendo específicas para cada país.

Abstract:
The objective of this scoping review was to identify the validation process and the methodological characteristics of food insecurity perception scales validated in different parts of the world. A search was carried out in the PubMed, Embase, Scielo, Mediline, Lilacs and Google Scholar databases, in addition to the gray literature. The pre-ion of studies took place by reading the titles and abstracts, followed by reading in full. Of the 828 studies identified, 19 were ed referring to 21 country scales: Colombia; Tanzania; Lebanon; New Zealand; U.S; Ecuador; Sir Lanka; Brazil; Guatemala; Dominican Republic; Haiti; Costa Rica; Venezuela; Mexico; Bolivia; Burkina Faso and the Philippines, as well as the Latin American and Caribbean Scale (ELCSA) and the FAO. Colombia and Ecuador presented two validated scales. The scales varied in relation to the year of validation (2000 to 2020), reference time (last 3 to 12 months), number of questions (7 to 18) and types of households (urban and rural). The validation processes involved qualitative and quantitative phases. Internal validation was performed using Cronbach\'s Alpha coefficient and the Rasch model; and the external one by association and/or correlation with socioeconomic and food consumption variables. Thus, the identified scales presented validation processes and different methodological characteristics, being specific to each country.
