“…A good example of evaluation of content validity using expert judges is seen in the work of Augustine et al on adolescent knowledge of micronutrients ( 48 ). After identifying a list of items to be validated, the authors consulted experts in the field of nutrition, psychology, medicine, and basic sciences.…”

Scale development and validation are critical to much of the work in the health, social, and behavioral sciences. However, the constellation of techniques required for scale development and evaluation can be onerous, jargon-filled, unfamiliar, and resource-intensive. Further, it is often not a part of graduate training. Therefore, our goal was to concisely review the process of scale development in as straightforward a manner as possible, both to facilitate the development of new, valid, and reliable scales, and to help improve existing ones. To do this, we have created a primer for best practices for scale development in measuring complex phenomena. This is not a systematic review, but rather the amalgamation of technical literature and lessons learned from our experiences spent creating or adapting a number of scales over the past several decades. We identified three phases that span nine steps. In the first phase, items are generated and the validity of their content is assessed. In the second phase, the scale is constructed. Steps in scale construction include pre-testing the questions, administering the survey, reducing the number of items, and understanding how many factors the scale captures. In the third phase, scale evaluation, the number of dimensions is tested, reliability is tested, and validity is assessed. We have also added examples of best practices to each step. In sum, this primer will equip both scientists and practitioners to understand the ontology and methodology of scale development and validation, thereby facilitating the advancement of our understanding of a range of health, social, and behavioral outcomes.

“…Lack of validated tools for measurement of behavior change may also hinder the process of building good health promotion programs. Of late there has been an increased awareness on the issue of psychometric validation of the instruments used for behavior change ( 110 , 111 ). Need for targeted nutrition education messages which are relatively easily understood and ready to implement is yet another important issue to be focused.…”

Global data indicate a high prevalence of hidden hunger among population. Deficiencies of certain micronutrients such as folic acid, iodine, iron, and vitamin A have long lasting effects on growth and development and therefore have been a National priority from many decades. The strategy implemented so far limits to the use of supplemental sources or fortified foods in alleviating the burden of deficiencies. These approaches however undermine the food-based strategies involving dietary diversification as the long-term sustainable strategy. There is lack of understanding on the level of evidence needed to implement such strategies and the level of monitoring required for impact evaluation. Dietary diversity concerns how to ensure access for each individual to a quality and safe diet with adequate macro- and micronutrients. The key to success in using dietary diversity as a strategy to tackle hidden hunger is in integrating it with the principles of bioavailability, translated to efficient food synergies with due emphasis on food accessibility, affordability, and outdoor physical activity/life style modifications. Promoting enabling environment and sustainable agriculture is crucial for practicing dietary diversification with behavior change communication as an integral segment. It can be concluded that food-based strategies require careful understanding of the factors associated with it and moderate it to form an effective strategy for controlling multiple micronutrient deficiencies.

Background: In India, virtually, no study was aimed to develop a psychometrically valid and reliable questionnaire to assess the nutrition knowledge and practice among parents of children aged between 3 and 6 years. Objective: The present study describes an evaluation of validity and reliability measures in a questionnaire designed for the assessment of nutrition knowledge among parents of children participating in a study finding relationship between physical growth and development and nonverbal intelligence quotient development being undertaken in a semi-urban area. Design: This was a cross-sectional school-based reliability and validity study. Setting: This study was conducted in seven primary schools within the limits of Purba (East) Barddhaman district legislation, West Bengal, India. Participants: One hundred and thirty-four parents of children aged 3–6 years were included in the study. Results: The final questionnaire consisted of 32 questions that were selected on the basis of content validity. Questions included closed-ended and multiple-choice items which could be answered correctly by 5%–95% of the target population with a difficulty index of 0.33–0.87, discrimination index of 0.12–0.44, and validity index of 0.10–0.86. Internal reliability of each item as measured by Cronbach's α of 0.87 was also significant. Conclusions: The test comprises basic psychometric criteria of a valid and reliable 32-item knowledge questionnaire which further forms an instrument for measuring current scenario and interpreting changes associated with intervention work aiming improvement of dietary and nutrition knowledge-practice in the middle-to-low socioeconomic community.
