Content validity of an educational workshop based on the Dietary Guidelines for the Brazilian Population

Abstract

Objective To describe the development and validation of a workshop protocol for the implementation of the Dietary Guidelines for the Brazilian Population in primary healthcare units. Methods This descriptive study was developed in the state of São Paulo, Brazil, and it involved 20-25 professionals in the experimentation phase and 12 experts in the content validity phase. The workshop protocol was developed according to three theoretical references: Dietary Guidelines, Interprofessional Collaborative Practice and Critical Reflexive Methodology. The protocol consisted of four 4-hour modules, 16 activities in 16 hours. The activities matrix was composed of three axes: (a) organizational strategies, (b) dietary guideline comprehension and (c) dietary guideline implementation. For the validity analysis, the expert panel assessed clarity, relevance and theoretical representativeness. Content validity index was calculated, and adequate activities scored >0.80. The proportion of experts who recognized the presence of the theoretical framework in the activities was calculated. Results All 16 proposed activities obtained a score greater than the established cut-off point, both for clarity and relevance. For theoretical representativeness analysis, the dietary guidelines reached higher scores on the (b) and (c) axes of the protocol and was less recognized on the (a) axis, whose highest score was for the Critical Reflexive Methodology. Interprofessional Collaborative Practice presented a higher score on the (c) axis and a lower one on the (b) axis. Conclusion The protocol was considered appropriate for its purpose and with potential application in the different scenarios of primary health care in Brazil.

Improving knowledge, self-efficacy and collective efficacy regarding the Brazilian dietary guidelines in primary health care professionals: a community controlled trial

“…With the purpose of testing its reproducibility in other teams in the country, the protocol was also validated by a panel of experts through content validation regarding its relevance, its clarity and the theoretical framework used for its development. The protocol and its validation are described in detail in a previous publication [ 19 ].…”

Content validation of the Nutritional Attention Assessment Instrument in Primary Health Care

“…Instrumento de Avaliação da Atenção Nutricional content validation was performed, using the Delphi technique, a method based on the approach to consensus through an experts' panel judgment on a problem [26]. This technique is widely used in health studies, such as, for example, building consensus on curriculum, training, professional skills, clinical practice and interventions and also for validating models of action and development of indicators [27][28][29][30][31][32][33][34].…”

“…To compose the experts' panel, nutritionists from all Brazilian macro-regions were invited. The selection of these professionals is justified on account of their specific skills in promoting improvement of the actions of Nutritional Attention with the teams from the Núcleo Ampliado de Saúde da Família e Atenção Básica (eNASF-AB, Expanded Family Health and Primary Health Care, from the Estratégia Saúde da Família (FHS, Family Health Strategy and from PHC [34,41].…”

Developing and refining behaviour-change messages based on the Brazilian dietary guidelines: use of a sequential, mixed-methods approach

“…They detail the most recent scientific evidence on the relationship between diet and health and provide advice on healthy food choices for preventing countryspecific, diet-related non-communicable diseases (NCDs). The Dietary Guidelines serve as the foundation for nutrition education material, the basis of federal feeding programs, school meals, procurement standards, and inform programs, policies and communication efforts [2][3][4]. Like other Dietary Guidelines (DG), the 2014 Brazilian Dietary Guidelines (BDG) present evidence-based recommendations for the population on food choices and the avoidance of industrialized, ultraprocessed foods but go further in their coverage of topics ranging from the introduction of the NOVA classification (a system that categorizes food based on their purpose and extent of processing) meal structures, and modes of eating to presenting strategies for overcoming barriers to healthy eating [5].…”
