Testing a Theory of Implementation Leadership and Climate Across Autism Evidence-Based Interventions of Varying Complexity.

This study looked at how school principals' leadership affects how well teachers use autism interventions in classrooms. Researchers studied three different teaching methods in 65 schools and found that when principals were strong leaders in supporting these programs, it created a better school environment that helped teachers use the most complex intervention more effectively. However, leadership didn't seem to matter as much for simpler interventions. This suggests that having supportive leadership is especially important when schools try to implement more complicated autism programs.

This study examined how school leadership and organizational climate influence teachers' ability to implement three autism interventions with varying complexity levels in 65 schools. Researchers assessed principals' implementation leadership behaviors and school climate, then observed teacher fidelity to pivotal response training (PRT), discrete trial training (DTT), and visual schedules. Results showed that strong principal leadership created better implementation climates, which predicted higher fidelity to the most complex intervention (PRT) but not to simpler interventions (DTT, visual schedules). The effect size was moderate (d = 0.49) for the relationship between leadership and PRT fidelity through climate.

Findings suggest organizational factors are particularly important for implementing complex behavioral interventions in schools.

Schools implementing complex autism interventions should prioritize developing strong principal leadership and positive organizational climate. Simple interventions may not require as intensive organizational support. Training programs should include leadership development components, particularly when introducing complex evidence-based practices in educational settings.

Single study design without randomization. Self-report measures for leadership and climate variables. Limited to school settings and specific grade levels (K-3). Sample size not reported, limiting assessment of statistical power. No long-term follow-up data provided.

Prominent theories within the field of implementation science contend that organizational leaders can improve providers' fidelity to evidence-based practices (EBPs) by using focused implementation leadership behaviors that create an organizational climate for EBP implementation. However, this work has been criticized for overreliance on nonspecific, self-report fidelity measures and poor articulation of the boundary conditions that may attenuate leadership and climate's influence. This study tests the predictions of EBP implementation leadership and climate theory on observed fidelity to three school-based EBPs for autism that vary in complexity: pivotal response training (PRT), discrete trial training (DTT), and visual schedules (VS). Educators in kindergarten to third-grade autism support classrooms in 65 schools assessed their principals' EBP implementation leadership and school EBP implementation climate prior to the school year.

Mid-school year, trained observers rated educator fidelity to all three interventions. Expert raters confirmed PRT was significantly more complex than DTT or VS using the Intervention Complexity Assessment Tool for Systematic Reviews. Linear regression analyses at the school level indicated principals' increased frequency of EBP implementation leadership predicted a higher school EBP implementation climate, which in turn predicted higher educator fidelity to PRT-however, there was no evidence of a relationship between implementation climate and fidelity to DTT or VS. Comparing principals whose EBP implementation leadership was ±1 SD from the mean, there was a significant indirect association of EBP implementation leadership with PRT fidelity through EBP implementation climate (d = 0.49, 95% CI [0.04, 0.93]).

Strategies that target EBP implementation leadership and climate may support fidelity to complex behavioral interventions.
