This study is being done to test the feasibility of a personalized nutrition eating plan in adolescents with depression. Evidence suggests that dietary quality may affect an individual's mood. A healthy diet includes vegetables, fruit, nuts, seeds, and olive oil, as well as minimally processed whole grains, legumes, and moderate amounts of lean meat, fish, and dairy.
The investigators will examine the feasibility of a personalized nutrition eating plan for children and youth with depression. Previous research has shown that it helps improve depressive symptoms in adults, but it is not clear if the same is true for children and youth.
The proposed 8-week, mixed-methods, single-arm study aims to examine the feasibility of an adjunctive personalized dietary intervention for adolescents with major depressive disorder. The secondary aims are to determine potential barriers and facilitators of implementation and to improve adherence and uptake.

| Dietary Intervention | Other | Four nutrition counselling sessions conducted over eight weeks, in conjunction with food items to assist in meal preparation and with weekly educational information messages sent via email. |
| Measure | Description | Time Frame |
|---|---|---|
| Feasibility of the Intervention | Feasibility of Intervention Measure (FIM). The FIM is a self-reported four-item measure scored using a five-point Likert scale ranging from 'completely disagree' (1) to 'completely agree' (5) with higher scores indicating greater acceptability or feasibility. Higher scores indicate greater feasibility with a maximum score of 20. | Baseline, 9 weeks |
| Acceptability of the Intervention | Acceptability of Intervention Measure (AIM). The AIM is a self-reported four-item measure scored using a five-point Likert scale ranging from 'completely disagree' (1) to 'completely agree' (5) with higher scores indicating greater acceptability or feasibility. Higher scores indicate greater acceptability with a maximum score of 20. | Baseline, 9 weeks |
| Feasibility, Acceptability, and Satisfaction of the Intervention | Feasibility, Acceptability, and Satisfaction are also assessed using semi-structured qualitative interviews pre- and post-study intervention. | Baseline, 9 weeks |
| Measure | Description | Time Frame |
|---|---|---|
| Depression symptoms | Depression symptoms are assessed using the Centre for Epidemiological Studies Depression Scale for Children (CES-DC), a validated 20-item self-report measure. Participants rated their symptoms on a four-point Likert scale, with higher scores indicating more severe depression symptoms, and a maximum total score of 60. | Baseline, 5 weeks, 9 weeks |

| Dietary Assessment | Adolescents' adherence to the personalized nutrition intervention is assessed using the Mediterranean Diet Quality Index for children and adolescents (KIDMED) questionnaire, a 16-item self- or interviewer-administered measure. Scores range from 0-12. A total score of ≤ 3 indicates poor adherence; a score of 4-7 indicates moderate adherence; a score of ≥8 indicates high adherence. | Baseline, 5 weeks, 9 weeks |
| Nutrition Attitudes and Knowledge questionnaire | Nutrition attitudes and knowledge are assessed using a Nutrition Attitudes and Knowledge questionnaire, designed to evaluate children's understanding of the 2019 Canada Food Guide (CFG). The questionnaire consists of four five-point Likert scale questions to measure positive attitudes about nutrition with higher scores indicating a stronger belief that healthy eating is important and a maximum score of 20. Additionally, 20 multiple-choice and true/false questions relate to CFG food groups (Drinks, Whole Grain Foods, Vegetables and Fruit, and Protein Foods). Higher scores indicate greater nutrition knowledge and the maximum possible score is also 20. | Baseline, 9 weeks |
| Parent Food Modelling: | Parental food modelling is evaluated with 10 items adapted from Cullen's scale, each rated on a four-point Likert scale from 'Never' (0) to 'Always' (3) which has been used to predict diet outcomes in adolescent samples. Higher scores signify greater healthful parental food modeling, with a maximum score of 30. | Baseline, 9 weeks |
| Satisfaction with menu planning | Satisfaction with menu planning is evaluated through a single item, independently assessed by parents and adolescents using a five-point Likert scale that ranges from 'very dissatisfied' (1) to 'very satisfied' (5). | Baseline, 9 weeks |
| Satisfaction with nutrition counselling sessions | Satisfaction with nutrition counseling sessions is evaluated through a single item, independently assessed by parents and adolescents using a five-point Likert scale that ranges from 'very dissatisfied' (1) to 'very satisfied' (5). | Baseline, 9 weeks |
