Intent of a Study Purpose statement: Overall direction i.e., The purpose of this grant is to enhance and expand existing partnerships. The Partnership and Community Readiness section of the application should demonstrate that a school-community partnership has been in existence for 6 or more months prior to submission of the application (henceforth referred to as preexisting school-community partnership). The preexisting school community partnership should involve at least two of the four required SS/HS partners that have worked together on issues of school safety, drug and violence prevention, and/or healthy childhood development issues for 6 or more months prior to submission of the application.
Work Plan Requirements… The SS/HS Initiative draws on the best practices of education, justice, social services, and mental health systems to provide integrated and comprehensive resources for prevention programs and prosocial services for youth. This comprehensive plan include six elements to address problems of school violence and alcohol and other drug abuse: ♦ Element 1: Safe school environment. ♦ Element 2: Alcohol and other drugs and violence prevention and early intervention programs. ♦ Element 3: School and community mental health preventive and treatment intervention services. ♦ Element 4: Early childhood psychosocial and emotional development programs. ♦ Element 5: Supporting and connecting schools and communities. ♦ Element 6: Safe school policies.
Grant Measurements… GPRA1 – SS/HS grant sites will experience a decrease in the number of violent incidents at schools during the 3-year grant period. GPRA2 – SS/HS grant sites will experience a decrease in substance use during the 3-year grant period. GPRA4 – SS/HS grant sites will increase mental health services to students and families during the 3-year grant period.
Grant Outcomes… GPRA1 – SS/HS grant sites will experience a decrease in the number of violent incidents at schools during the 3-year grant period. Outcomes: Objective 1. In each of three years cumulatively, decrease by 60% the percentage of violent incidence occurrence for each of the categories: threatening behavior, unprovoked attack on student, fighting, fighting with or threatening teacher, possession or use of dangerous weapon, arson, and endangering safety of others. GPRA2 – SS/HS grant sites will experience a decrease in substance use during the 3-year grant period. Outcomes: Objective 2. In each of three years cumulatively, decrease by 60% the percentage of substance abuse occurrence for each of the categories: alcohol, tobacco, and controlled substances (possession or use). GPRA4 – SS/HS grant sites will increase mental health services to students and families during the 3-year grant period. Outcome: Objective 4. In each of three years cumulatively, increase by 50% the percentage of students and families accessing and receiving mental health services, as measured by frequency of service requested or inquired about, follow-through in accessing such service, and persistence in pursuing such service to closure.
Is the study feasible? • Tradeoffs between rigor and practicality. You may have to: • Control the implementation of your program more carefully. • Ask program participants lots of questions. • Evaluate research rigor, desire and practicality.
Is the study feasible?…cont. • Practical considerations for a feasible research project: • How long the research will take to accomplish. • Ethical constraints • Needed cooperation • Costs.
GPRAs &Outcomes (Research Questions)
Quantitative Research Questions • Quantitative research is mainly concerned with the degree in which phenomena possess certain properties, states and characters, and the similarities, differences and causal relations that exist within and between.
Qualitative Research Questions • Qualitative research is concerned with the properties, the state and the character (i.e., the nature, of phenomena). Emphasis on processes and meanings.

Qualitative Analysis • Qualitative analysis seeks to capture the richness of people's experience in their own terms. Understanding and meaning emerge from in-depth analysis of detailed descriptions and verbatim quotations.
