Network-Based Support to Help Community Coalition Members Choose and Use Strategies to Improve Child Health

Participation and Reach

The number of eligible coalition members who provide informed consent and complete at least one study data-collection activity will be divided by the total number of eligible coalition members invited to participate and multiplied by 100. Scores range from 0% to 100%. Higher percentages indicate greater study reach.

Percentage of Enrolled Participants Retained Through the Primary Endpoint

The number of participants in the baseline cohort who complete the final scheduled primary assessment will be divided by the number enrolled in the baseline cohort and multiplied by 100. Scores range from 0% to 100%. Higher percentages indicate greater retention.

Mean Acceptability of Intervention Measure Score for FICAS

Acceptability of FICAS will be measured using the four-item Acceptability of Intervention Measure. Each item is scored from 1, completely disagree, to 5, completely agree. Item scores will be averaged to produce a mean score ranging from 1 to 5. Higher scores indicate greater perceived acceptability. Mean scores will be reported separately at each assessment.

Mean Intervention Appropriateness Measure Score for FICAS

Perceived appropriateness of FICAS will be measured using the four-item Intervention Appropriateness Measure. Each item is scored from 1, completely disagree, to 5, completely agree. Item scores will be averaged to produce a mean score ranging from 1 to 5. Higher scores indicate greater perceived appropriateness. Mean scores will be reported separately at each assessment.

Percentage of Selected-Strategy Adoption Milestones Completed

Coalition progress will be assessed using eight prespecified milestones: naming and actively considering a candidate strategy, formally selecting a strategy, assigning implementation roles, drafting an implementation plan, securing resources or commitments, completing launch preparation, initiating the first implementation activity, and beginning early monitoring or refinement. Each completed milestone receives one point. The number completed will be divided by eight and multiplied by 100. Scores range from 0% to 100%. Higher percentages indicate greater progress from strategy consideration through adoption and early action.

Normalized Early Implementation Readiness and Action-Initiation Score

Readiness and action initiation will be assessed using a nine-indicator study-specific rubric. Indicators address confirmation of the selected strategy, implementation leadership, assigned responsibilities, a written implementation plan, timelines and milestones, resources and supports, partner commitments, launch preparation, and initiation of the first implementation action. Each applicable indicator is scored from 0, no evidence, to 3, completed or fully documented. Scores will be summed, divided by the maximum possible score for applicable indicators, and multiplied by 100. Scores range from 0 to 100. Higher scores indicate greater implementation readiness and action initiation.

Coalition Child-Health Discussion Network Density

At each assessment, participants may identify up to 20 people with whom they currently discuss child health promotion. Coalition network density will be calculated as the number of observed directed child-health discussion ties among rostered coalition members divided by the total number of possible directed ties, excluding self-ties. Scores range from 0 to 1. Higher values indicate a more densely connected coalition discussion network.

Percentage of Child-Health Discussion Ties Connecting Different Sectors

The number of reported child-health discussion ties connecting people from different organizational or community sectors will be divided by the number of reported ties with sector information and multiplied by 100. Scores range from 0% to 100%. Higher percentages indicate greater cross-sector connectivity.
