MyChoice: An Application of the Three-Factor Eating Questionnaire (TFEQ-R18v2) Among Adolescent and Young Adult Survivors of Central Nervous System (CNS) Tumors
A one-time assessment will be conducted for all participants through the Assessment Center
website. No treatment or intervention will be provided. Two websites will be set up (Site
A and Site B). The only difference between the two sites is the order that the questions
will appear. The actual questions will remain the same. Only the adolescent and young
adult (AYA) survivors of CNS tumors eligible after screening will be invited to respond to
the survey. Following the final screening, the eligible participants will be randomized to
Site A or Site B.
Each participant will complete the web-based questionnaire that has a total of 53 questions.
For site A, the order of the questions will be TFEQ-R18v2, multifactor screener, and
EQ-EMA. For site B, the order of the questions will be EQ-EMA, multifactor screener, and
TFEQ-R18v2. The 53 questions came from the original TFEQ-R18v2, the multifactor screener
used in the National Cancer Institute's Observing Protein and Energy Nutrition Study, and
the adapted TFEQ-R18v2 for use via EMA methodology.
Multifactor screener is a short assessment tool used to evaluate dietary intake of fruits,
vegetables, percentage of energy from fat, and fiber.
Eating Questionnaire-EMA (EQ-EMA) was adapted based on the original TFEQ-R18v2 for use via
EMA methodology. The changes made were related to a change in verbiage to reflect our goal
of assessing a participant's current behavior before and after an eating episode.
Observational Model: Case-Only, Time Perspective: Prospective
Factor Structure Comparisons of Eating Questionnaires
Structural equation modeling (SEM) methodology (i.e. confirmatory factor analysis) used to examine extent to which individual items comprising both the original Three Factor Eating Questionnaire-R18v2 (TFEQ-R18v2) and the adapted Eating Questionnaire-Ecological Momentary Assessment (EQ-EMA) loaded on their respective factors cognitive restraint and uncontrollable eating (CR and UE) and will examine the correlations between them. Analyses conducted using Mplus (version 6.12).
