This study investigates the use of the Observe-Orient-Decide-Act (OODA) loop to improve collaboration between schools and medical/welfare services in preventing child suicide in Japan. A questionnaire survey of 171 teachers, nurses, welfare professionals, and school counselors revealed that those dissatisfied with current collaboration had poorer self-rated health, despite similar depressive symptom levels. Three factors emerged regarding attitudes toward the OODA loop: flexible situational assessment, group monitoring, and self-monitoring. Dissatisfied participants scored lower on all three. Analysis of free-text responses identified three categories of reasons for satisfaction/dissatisfaction: collaboration details, methods, and organization. The study concludes that raising OODA awareness, creating organizational structures, and establishing collaborative systems are crucial for suicide prevention.
