Cross-Sector Collaboration Assessment Instrument for Handling Stunting in Gorontalo Province: Indicators, Validity, and Reliability

Cross-sector collaboration plays a crucial role in addressing stunting by fostering partnerships among organizations from various sectors. This study aimed to develop and validate reliable indicators to evaluate cross-sector collaboration within the stunting reduction program in Gorontalo Province, Indonesia. A questionnaire was formulated following an initial qualitative study and administered to 32 members of the stunting reduction acceleration team. The instrument consisted of 10 domains encompassing 95 items. Validity testing confirmed 93 items as valid, while two were excluded. Reliability analysis using Cronbach’s Alpha demonstrated exceptional reliability for the domains of cross-sector role and structure, and cross-sector performance. Six additional domains—including vision and mission, partner profile, resource availability, leadership, communication, and partnership function—showed very good reliability. One domain exhibited good reliability (cross-sector context), and another moderate reliability (need for cross-sector collaboration). The findings offer a comprehensive and validated set of indicators to assess the effectiveness of cross-sector collaboration in stunting management. These indicators serve as a foundation for systematic evaluation, contributing to improved coordination and program outcomes in Gorontalo Province.
