Assessing the Feasibility and Acceptability of Watching Queen of Katwe as a Role Model Intervention Among Adolescents in High Schools in Kenya

Primary outcomes

1. Mean change in aspiration score from baseline on the Aspirations Index through study completion

   Time frame: From baseline through endline, an average of two days

   Changes in self-reported aspirations as measured by the Aspiration Index is used to assess long term aspirations and goals that individuals hope to accomplish in their lives. In this study, we will use a shortened 15-item version of this scale including items on aspirations of wealth, fame, image, personal growth, relationship, community and health. The scores for each item ranges between 1-7, with higher scores indicating higher aspirations.

2. Mean change in school engagement score from baseline on the School Engagement Measure through study completion.

   Time frame: From baseline through endline, an average of two days

   Changes in self-reported school engagement as measured by the School Engagement Measure refer to a student's emotional, behavioural, and cognitive involvement in school activities and learning. This is a 19-item measure with responses measured on a 5-point Likert scale ranging from 1 (not at all true) to 5 (very true). Higher scores indicate greater school engagement.

3. Change in academic performance as measured using the average grades

   Time frame: Periprocedural - From academic exam results pre-intervention to academic exam results post-intervention, up to three months

   Changes in academic performance as measured using the average grades obtained from the most recent exam prior to the intervention, and the first available exam following the implementation of the intervention.

4. Mean score of the Feasibility of Intervention Measure at study completion

   Time frame: At study completion, up to three months

   Feasibility of Intervention Measure tracks metrics such as ease of setting up the screenings, logistical challenges, and time constraints. It assesses the extent to which an intervention can be successfully implemented within a given setting. This is a 4-item measure with responses measured on a 4-point Likert scale ranging from 1 (Completely disagree) to 5 (Completely agree). Higher scores indicate a better outcome, good scores on the feasibility of the intervention.

5. Mean score of the Acceptability of Intervention Measure at study completion

   Time frame: At study completion, up to three months

   Acceptability of Intervention Measure assess the acceptability of the intervention by participants. This 4-item measure evaluates stakeholders' perception of an intervention's acceptability, determining whether they find it agreeable, satisfactory, or palatable. Responses are measured on a 4-point Likert scale ranging from 1 (Completely disagree) to 5 (Completely agree). Higher scores indicate a better outcome, the acceptability of the intervention.

6. Mean score of the Intervention Appropriateness Measure at study completion

   Time frame: At study completion, up to three months

   Intervention Appropriateness Measure assesses perceptions of participants' intervention appropriateness. It measures the perceived fit, relevance, or compatibility of an intervention within a particular context. This 4-item measure determines whether an intervention aligns with the needs of a specific population, organisational goals, or existing workflows. Responses are measured on a 4-point Likert scale ranging from 1 (Completely disagree) to 5 (Completely agree). Higher scores indicate a better outcome, the appropriateness of the intervention.
