Individual cognitive interviews and guided-small group discussions will be conducted with 20 to 24 children age 10-12 and 20 to 24 teens age 13-16 to assess whether the food security questions can be adapted for use with children/youth. The questions will be revised, based on findings from the initial interviews, and formatted into questionnaires for interviewer-administered and self-administered surveys. The questionnaires will then undergo a final phase of cognitive testing, using retrospective probing to assess the children's ability to complete the survey questionnaire without aid from an interviewer and to follow any skip patterns in the instrument in a more realistic survey environment. Based on the findings from this phase, final recommendations will be made on the wording of questions, the format for self administration, scale construction, and the minimum age at which children can be expected to comprehend the food security items and complete the survey.
