A stepped-wedge randomized trial investigating the effect of the Leadership and Organizational Change for Implementation (LOCI) intervention on implementation and transformational leadership, and implementation climate

BACKGROUND: This study evaluates the Leadership and Organizational Change for Implementation (LOCI) strategy and its effect on implementation leadership, transformational leadership, and implementation climate. METHODS: A stepped wedge cluster randomized study design enrolling 47 first-level leaders from child- and adult-specialized mental health clinics within Norwegian health trusts across three cohorts. All therapists (n = 790) received training in screening of trauma exposure and posttraumatic stress, and a subgroup of therapists (n = 248) received training in evidence-based treatment methods for posttraumatic stress disorder (PTSD). First-level leaders and therapists completed surveys at baseline, 4, 8-, 12-, 16-, and 20-months assessing leadership and implementation climate. General linear mixed-effects models were used to investigate whether the LOCI strategy would lead to greater therapist-rated scores on implementation leadership, transformational leadership, and implementation climate. RESULTS: After introducing the LOCI strategy, there was a significant increase in therapist-rated implementation and transformational leadership and implementation climate. The increase was sustained at all measurement time points compared to non-LOCI conditions, which demonstrated a steady decrease in scores before LOCI. CONCLUSIONS: The LOCI strategy can develop better transformational and implementation leadership skills and contribute to a more positive implementation climate, which may enhance successful EBP implementation. Thus, LOCI can help leaders create an organizational context conducive for effective EBP implementation.
