A Study Of The Effectiveness Of A Workplace Violence Intervention For Small Retail And Service Establishments

Objective: Examine the effectiveness of a robbery and violence prevention program in small businesses in Los Angeles. Methods: Gas/convenience, liquor and grocery stores, bars/restaurants, and motels were enrolled between 1997 and 2. Intervention businesses (n = 35) were provided training, program implementation materials, and recommendations for a comprehensive security program. Control businesses (n = 96) received neither training nor program materials. Results: Rate ratios comparing intervention to control businesses were .9 for violent crime (95% confidence limits [CL] = .53, 1.53) and .81 for robbery (95% CL = .38, 1.73). The reduction in violent crime was concentrated in high-compliance intervention businesses (risk ratio = .74, 95% CL = .4, 1.36). Low-compliance intervention businesses had practically the same postintervention crime as the control businesses. Conclusions: Our results suggest that the workplace violence intervention may reduce violent crime among high-risk businesses, especially those with high program compliance.
