Project Daire: Derry/Londonderry as the Nexus City for Food, Education, Trust and Health (Daire)

실험적: Engage

The Engage intervention was developed with input from primary school teachers and includes a range of age-appropriate educational activities related to food. Activities include videos, lesson plans, worksheets, games, talks/visits from experts, visits to industrial partners and other local food-related centres of interest and practical activities such as experiments. All 'Engage' material is mapped to the Northern Ireland School Curriculum. The 'Engage' intervention is structured into three broad topics: Farm to Fork; Pleasure on a Plate and Food Futures. Engage resources were provided to schools electronically and in hard copy and teachers delivered most of the content, with the exception of several sessions which were delivered by visiting scientists.

간섭 없음: Delayed

The delayed arm of the intervention was the control arm. Schools randomised to this arm of the study were offered the Engage intervention resources after endpoint data collection.

Change in KIDSCREEN-10 score at 6 months

Validated well-being questionnaire for children. Completed by KS1 and KS2 pupils.This is an 11-item instrument answered on a 5-point scale and results in one global HRQoL score. Most of the items are formulated positively and in concordance with the scoring, which means a higher score reflects a higher HRQoL. However, some items are formulated negatively and as a consequence the scoring has to be recoded. The scoring method results in T-values with scale means around 50 and standard deviations around 10 with higher values indicating higher HRQoL.

Change in Strengths and Difficulties Questionnaire score at 6 months

Validated brief behavioural screening questionnaire. Completed by teachers. This 25-item instrument incorporates 5 scales of 5 items, with each item answered on a 3 point scale. All scales represent a negative trait, with the exception of the ProSocial Scale which indicates a positive trait. For each of the 5 scales the score can range from 0 to 10 if all items were completed. A Total Difficulties score is the final score and indicates poorer behaviour. Therefore the lower the score, the better the outcome in terms of behaviour.

24 Hour Dietary Record

Validated dietary intake questionnaire in age group (Moore et al., Br J Nutr 2008;99:1266-74). Completed by KS1 and KS2 pupils. Prospective record of all foods and drinks consumed over a 24 hour period. Data are analysed using dietary analysis software to produce average daily intake of food groups, macronutrients, micronutrients, vitamins and minerals.

Food Frequency Questionnaire

Food Frequency Questionnaire developed by study team based on other similar age-appropriate food frequency questionnaires (Cade et al., Public Health Nutr 2005;9:501-8). Two versions-one shorter version developed for younger KS1 age group, one for KS2 age group. Children asked to indicate categorical responses ('yes', 'no' and 'not sure') to indicate whether or not they ever eat a particular food. Presented as a food group list with categorical responses.

Food Shopping, Preparation & Consumption

Questionnaire developed by study team. Completed by KS1 and KS2 pupils. Children asked to indicate categorical responses 'always', 'sometimes', 'never' or 'agree' 'not sure' or 'do not agree' with reference to various cooking, food preparation scenarios and how they feel about trying new foods.

Perceived cooking competence

Researcher developed questionnaire (items sourced from unpublished data), based on similar measures for perceived movement competence (Barnett et al., 2015; Harter and Pike, 1984). Completed by KS1 and KS2 pupils-shorter version developed for KS2 pupils. Categorical responses 'yes' and 'no' with regards to have they ever demonstrated a range of different cooking skills. Children are then presented with a range of illustrated characters who vary in their competence and child indicates which child they are most like with regards to that particular cooking skill.

Agri-Food Knowledge

Questionnaire designed to assess pupil knowledge on range of agri-food topics (food chain, farm, seasonality, local versus imported). Researcher developed with industry input, piloted and face validity with experts in the different fields, some items adapted from previous measures (Moss et al., 2013; Reynolds et al., 2012; Harmon and Maretzki, 2006; Saksvig et al., 2005) and BNF - Food a fact of Life (http://archive.foodafactoflife.org.uk/Activity.aspx?siteId=14§ionId=63&contentId=176). Completed by KS1 and KS2 pupils-shorter version developed for KS1 pupils. Responses categorical and categories varied by item type.

Food Jobs/Careers Aspirations

Questionnaire to assess career aspirations and knowledge of food-related jobs. Developed by research team. Completed by KS1 and KS2 pupils. Open-ended questions asking about career aspirations and assessing knowledge of careers related to food.

Preference/Willingness to Try

Completed by KS1 and KS2 pupils-shorter version for KS1 pupils.Responses largely categorical with some open-ended questions asking children to identify the food.

Attitudes

Questionnaire to assess pupil attitude to importance of health behaviours, including diet. Previously used in a survey of NI schoolchildren health (Young Hearts Studies). Completed by KS2 pupils only. This is an 11-item instrument assessing attitudes towards importance of various health behaviours 'very important', 'quite important', 'not important'

Food source to product - knowledge

Questionnaire to assess level of knowledge in terms of food source to product. Developed by research team. Completed by KS1 and KS2 pupils. Categorical matching responses.

School food environment questionnaire

Questionnaire designed to assess current school food environment. Developed by research team. Completed by school principal/management

Exposure to/Experience with Agri-Food

Questionnaire designed to characterise pupils in terms of previous experience of agri-food. Developed by research team. Developed with KS1 and KS2 age-appropriate questions. Categorical responses.

Baseline Skills Scale

Questionnaire designed to characterise pupil's level of cooking skills. Previously validated questionnaire. Children indicate how good they believe they are at various cooking skills on a 7-point scale (1 is very poor and 7 is very good).

Daire Evaluation questionnaire

Process Evaluation questionnaire for both Nourish and Engage interventions completed by teachers. Developed by research team. Categorical and op-ended responses.
