Differentiating Data, Information & Knowledge
DATA
KNOWLEDGE
INFORMATION disconnected facts
about events (objective)
data arranged in meaningful patterns
Information in context or put into action (subjective)
PRACTICE RESEARCH
Centre for Behavioural Research and Program Evaluation
Local Data Collection Systems
CBRPE & PHR at UW have developed a school-based data collection system
School Health Action, Planning and Evaluation System (SHAPES)
Designed to facilitate surveillance, evaluation and planning by school stakeholders and public health
Centre for Behavioural Research and Program Evaluation
SHAPES
Modular system
• Smoking• Physical activity
Each module has 3 components
• Student questionnaire• Feedback report• Administrator questionnaire
Centre for Behavioural Research and Program Evaluation
SHAPES Student Questionnaire
Centre for Behavioural Research and Program Evaluation
SHAPES Feedback Report
Centre for Behavioural Research and Program Evaluation
SHAPES Administrator Questionnaire
Completed by an administrator from each school:
• School characteristics• Policies• Programs• Facilities (PA)
Enables multiples levels of data collection and analysis
Centre for Behavioural Research and Program Evaluation
Key Features of SHAPES
Responsive questionnaire
Quality control
Simple and low cost
Knowledge exchange
Potential to compare across sites

Reliability of the PA Module
One-week test-retest
N=1586
Grades 9-12
13 secondary schools
Centre for Behavioural Research and Program Evaluation
Reliability Results
Kappa was between 0.61-1.0 for 57% of the questions (substantial agreement)
Kappa was between 0.41-0.60 for 24% of the questions (fair agreement)

Validity of the PA Module
Criterion validity
• Physical activity by accelerometers • BMI by measured height and weight
N=56
Grades 6, 7, 8, 10, 12
1 school
Centre for Behavioural Research and Program Evaluation
Validity Results
Self-reported vs. accelerometer measured time spent doing moderate-to-vigorous intensity physical activity (r = 0.44, p < 0.01)
Self-reported vs. measured BMI (r = 0.90, p < 0.001)

Current Uses of SHAPES in Ontario
SHAPES Ontario study (www.shapes.uwaterloo.ca)
• 100+ high schools in 8 health unit regions• PA & smoking modules• Schools receive feedback reports • Health units receive data for their region
KE component to SHAPES Ontario
• Creating “a community of practice” to build capacity to use school-based evidence
Centre for Behavioural Research and Program Evaluation
Current uses of SHAPES - continued
Youth Smoking Survey (www.yss.uwaterloo.ca)
• 2004-05; 2006-07 data collection in Ontario• Opportunities to analyze data & write reports
(CDIC supplement)• Examples of how modules can be altered for
specific groups Lungs are for Life evaluation
exposé evaluation (City of Ottawa Health Dept)
• 3-year follow-up of baseline data
Centre for Behavioural Research and Program Evaluation
Next Steps in SHAPES Development
Future modules
• Sun behaviour • Eating behaviour • School issues (e.g. bullying)
Interactive system to make data available to public health for local analysis
YSS 2007
