Previous research employing an institutional theoretical framework posits environmental factors play an integral role in the adoption of police practices. The present study applies this framework to examine the adoption of intelligence-led policing (ILP). Data from a purposive sample of national intelligence personnel from 254 agencies are used to employ both a measurement and structural model to explain ILP adoption. Weighted least squares estimation is employed through an asymptotic distribution free function to estimate the measurement and structural equation models. Models exhibit good fit indices, while institutional pressures, among others, had a significant and positive effect on ILP adoption. Findings support the role of institutional pressures in the diffusion of police practice. Implications for future research and policy are discussed.
