The purpose of this study was to explore the effectiveness of implementing Life Space Crisis Intervention as a school-wide strategy for reducing school violence. Life Space Crisis Intervention (LSCI) is a strength-based verbal interaction strategy (Long, Fecser, Wood, 2001). LSCI utilizes naturally occurring crisis situations as teachable moments. The literature review analyzes school violence, violence prevention programs and effective change practices. This study employed mixed research methods with a sample population of public school, LSCI trained, staff members in Central New York. The result of this study supports two conclusions: LSCI is an effective school-wide strategy, but was not implemented effectively or that LSCI is effective as part of a school-wide violence prevention continuum. Further research is warranted. [The dissertation citations contained here are published with the permission of ProQuest LLC. Further reproduction is prohibited without permission.
