For the treatment arm, girls will participate in the Body Project for about 30 minutes, then will be given about a 30 minute self-compassion-based nutrition education lesson. The nutrition topics will cover the basic biochemistry of nutrition, nutrition needs for teenage girls, and ways to find balance in eating, framed in the constructs of self-compassion. The three self-compassion constructs will be targeted in the following ways: (1) Mindfulness will involve bringing awareness to feelings and emotions about a time during the week where participants ate a food lower in nutritional value. (2) Common Humanity involves finding ways in which their experience connects to others and acknowledging that being human comes with imperfections. (3) Self-Kindness will involve having girls speak kind and understanding words to themselves as it relates to their eating-related downfall of the week.

For the control arm, participants will receive the same 30-minute Body Project class, then participants will be given a 30-minute nutrition education lesson. The nutrition lesson plans will have no components of self-compassion intertwined within the lesson, but the nutrition content will be the same as the treatment group.

The participants will be randomized into either a treatment or control group. For the treatment arm, girls will participate in the Body Project for 30 minutes, then will be given a 30-minute self-compassion-based nutrition education lesson. Nutrition topics will cover the basic biochemistry of nutrition, nutrition needs for teenage girls, and ways to find balance in eating, framed in the constructs of self-compassion. The control group will receive the same 30-minute Body Project class and the same 30-minute nutrition education class; however, there will be no incorporation of self-compassion.

The feasibility of this randomized controlled pilot will consider sample size. Feasibility will be measured by the length of time required to complete participant recruitment (=20-24).

The feasibility of this randomized controlled pilot will consider retention. Feasibility will be measured by the retention rate/response rate (100 %) at 1-month follow-up.

The feasibility of this randomized controlled pilot will consider randomization. Feasibility will be measured by the ability to randomize participants (if researcher needs to add additional class options to accommodate teen girls).

Program acceptability will be measured by focus groups conducted post-intervention and a credibility scale which will be given after classes. The Credibility scale measures the degree to which participants believe their intervention is credible and effective in improving outcomes (body image and nutrition). Some of the question items included, "How logical is this program in helping you improving eating habits? How logical is this program in helping you improve body image? Responses are indicated on a 9-point Likert scale of 0 (not at all) to 9 (very). Higher scores mean better outcomes.

My secondary objectives will test within and between groups (treatment vs control) changes in self-compassion. The Self-Compassion Scale for youth consists of 17 items to assess self-compassion through the components of self-kindness, self-judgment. Responses are indicated on a 5-point Likert scale ranging from 1 (almost never) to 5 (almost always). Higher scores mean better outcomes.
