Validity and reliability of online questionnaire on awareness, knowledge, attitude and self-efficacy (AKAS) on healthy eating for nutrition education and promotion

@#Introduction: This study entailed the process of developing an online questionnaire to determine awareness, knowledge, attitude and self-efficacy (AKAS) on healthy eating for nutrition education. Currently, there is no local validated questionnaire that can be used to assess AKAS on healthy eating among Filipino adults. Methods: The study developed the questionnaire based on theoretical frameworks and literature review. The draft questionnaire underwent three stages of development: (1) online modified Delphi technique composing of seven subject matter experts (SME) for content validity; (2) online cognitive debriefing with 32 participants (14 nutrition experts and 18 general public) for construct validity; and (3) online pre-testing with 35 participants (non-nutritionists) using test-retest method. Results: For first stage, the questionnaire contained 16 questions for awareness, 17 questions for knowledge, 17 questions for attitude, and 15 questions for self-efficacy. For second stage, significantly different scores (p-value<0.00) between nutritionist experts and general public were observed, showing good construct validity. For third stage, Spearman’s correlation of test-retest method was 0.640. The questionnaire yielded Cronbach’s alpha of 0.467 to 0.923 (round 1) and 0.435 to 0.923 (round 2). A second analysis was done to improve the internal consistency of the questionnaire. By combining two question categories (awareness and knowledge), the Cronbach’s alpha increased to 0.659 (round 2), and by deleting three questions in attitude category, the Cronbach’s alpha improved to 0.626 (round 2). Conclusion: The process used ensured the questionnaire’s validity and reliability. Hence, this online questionnaire may be adopted by parties interested in developing and assessing nutrition education.

Developing and pre-testing of nutrition cartoon video to promote healthy eating among hearing and deaf and mute children

@#Introduction: A six-minute nutrition cartoon video “The Magical Pinggang Pinoy in Nutrilandia” was developed and pre-tested to encourage hearing and deaf and mute children to eat a variety of foods by following the Pinggang Pinoy® (Healthy Plate). This study described the development process of the nutrition cartoon video and explored the participants’ acceptance towards it. Methods: The video underwent two levels of pre-testing to ensure comprehensibility, attractiveness, acceptability, and self-involvement. The first level was conducted among three DOST-FNRI experts, while the second level was among six deaf-mute school teachers and 30 mothers/ caregivers of 6-9 years old hearing children. Data were collected through an online self-administered questionnaire. Open-ended questions allowed participants to express themselves freely on the given subjects. Data analysis used thematic analysis. Results: The video conveyed clear information on the Pinggang Pinoy®, and the inclusion of animation, subtitles, visuals, and voice-over made the video easier to understand. Participants stated that the message of the video was directed to children, teens, adults, malnourished people, and everyone in general. Pre-testing the nutrition cartoon video before final production identified terminologies and concepts that participants found unfamiliar, confusing and unacceptable; offered suggestions for improvement and made pre-tested video appropriate for hearing and deaf-mute children. Conclusion: Overall, the participants had positive perceptions on the nutrition cartoon video. The video can be used in nutrition education classes among hearing and deaf and mute children, and serves as a tool to measure children’s nutrition knowledge on healthy eating.
