Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This observational study will collect data and address the following three specific aims. Aim 1: To determine if the total number and specific types of safety tactics and policies are associated with the occurrence of intentional shootings in a sample of 650+ K-12 public schools. Primary Aim 1 hypothesis -- The total number of cumulative safety tactics and policies will be significantly associated with intentional school shootings. Secondary Aim 1 hypothesis -- When organized into three domains (physical target hardening, emergency response and technologies, and school security), the total number of safety tactics and policies within each domain will be significantly associated with intentional school shootings. Aim 2: To determine if the total number and specific types of safety tactics and policies are associated with suspension and expulsion rates in a sample of 650+ K-12 public schools. Primary Aim 2 hypothesis -- The total number of cumulative safety tactics and policies will be significantly associated with student discipline outcomes. Secondary Aim 2 hypothesis -- When organized into three domains (physical target hardening, emergency response and technologies, and school security), the total number of safety tactics and policies within each domain will be significantly associated with student discipline outcomes. Aim 3: To identify if urban/non-urban, economic, and racial disparities prior to and following the onset of the COVID-19 pandemic exist in effect modification analyses of the relationships between the implementation of safety tactics and policies, suspensions and expulsions, and intentional shootings in K-12 public schools. Aim 3 Hypothesis: Significant urban/non-urban, economic, and racial disparities prior to and following the onset of the COVID-19 pandemic will exist in effect modification analyses of the relationships between the implementation of safety tactics and policies, suspensions and expulsions, and intentional shootings in K-12 public schools.
