Health professionals' perspectives on factors needed to implement nutrition strategy: A questionnaire validation study

Abstract

Background: Noncommunicable diseases (NCDs) increasingly recognized as a serious, worldwide public health concern. According to the WHO, NCDs are currently responsible for two-thirds of global deaths annually. Nutritional food and unhealthy diet are contributing to an immense portion of NCDs. Exploring the role of nutrition in healthcare delivery with a particular focus on the United Arab Emirates (UAE) context is also aligned with the UAE Government's Vision 2021.

Aim: To develop a reliable and valid questionnaire that helps to assess the agreement about factors needed to implement a nutrition strategy in the UAE.

Materials and Methods: One hundred and sixty-one health professionals were invited to respond to a questionnaire assessing agreement with factors needed to implement a nutrition strategy. The questionnaire consisted of 11 factors, each containing four items that made a total of 44 items assessed on a 7-point Likert scale (1 strongly disagree to 7 strongly agree). The questionnaire was evaluated using factor analysis, and Cronbach's alpha was used to test the internal consistency of the responses of participants. Ethical approval was given by the Chair of Humanities and Health Sciences Research Ethics Panel (UAE).

Results: The questionnaire was validated by an expert panel. A factor analysis was carried out through responses of the health professional and revealed that the 11 factors are included in the questionnaire; only one item from the factor of resources and enablement was excluded: the exclusion of the item “hospital uses the lifespan approach in nutrition interventions” due to singularity and insufficient load of the variance extracted.

Conclusion: The study concluded that the questionnaire was valid and reliable on its form of 43 items divided into 11 factors to assess the agreement toward factors needed to implement a nutrition strategy in the UAE.
