SOM UVA VPSA DPM ESHC DPNbS ODOS OHP Gordie-CASE CASE ISAS Health Promotion Survey (HPS) Health Behavior Survey (HBS)
Both Surveys • Used for over 10 years • Stratified random samples of undergrads • Over-sampled first years & minority students • Web-based • Spring time • Alcohol use focus
Problems Duplication of content, population, timing, uses Response rates Survey requests to students, especially of minority students Other surveys: • NCHA every three years • eChug for first-year students: baseline & follow-up • smaller surveys related to celebratory drinking events: • Halloween ● Last home football game • Spring break ● Foxfield
The Charge Merge the HPS and HBS into a single survey
The Team • Jennifer Bauerle • Susie Bruce • Adrienne Keller • Jason Shaffer
Question Everything • What is the primary purpose of this survey? • What do we need to know to accomplish that purpose? • What kind of survey will best accomplish our purpose? • How does each question contribute to accomplishing the purpose?
Primary Purpose To guide and evaluate social norms alcohol education interventions of OHP and CASE. • Is there change? • What changed? • Who changed? • Is change related to exposure to the interventions?
What We Need to Know • Demographics • Drinking Behaviors and Attitudes • Perception of Drinking Behaviors and Attitudes • Exposure to Education • Outcome Measures • Over time!
Over time! • Both HPS and HBS are REPEATED CROSS-SECTIONAL • Annual • New sample each year • Can examine POPULATION change but not INDIVIDUAL change • New Survey: LONGITUDINAL COHORT • Annual • Each participant receives the survey(s) for 4 years • Can examine INDIVIDUAL and POPULATION change Enroll Graduate
What We Want • Longitudinal cohort study: Follow a random sample of students through their undergraduate career at UVa • Online • Multiple survey points each year: • Yearly baseline: early Fall • Early December: survey focused on Halloween & “4th year 5th” • Late spring: survey focused on Spring Break and Foxfield
Behaviors Behaviors Perceptions Perceptions Negative Consequences Negative Consequences Population Periodic follow-up for 4 years Sample Exposure Relevant characteristics Problems Intervention Outcomes
?? Questioning Everything ??How will we use the information? • Do we want to compare to national trends? • Example: alcohol consumption • Do we want to compare to institutional data? • Example: race/ethnicity • What have we learned from past surveys? • Example: perception–reality gap • How do we assess exposure? • Penetration and saturation measures
?? Questioning Everything ?? • What do we need for publication? • Example: Stages of change measurement • What do we need for stakeholders? • Example: institution-specific events • What answer options do we want? • Categories, Menu of choices, Open-ended • How long will this take to complete? • “The one with the most data wins” vs • “The one with the smallest sample loses”
Design Process • Create a “map” • Collate existing survey questions into the map • Frequent team meetings • Examine data from previous surveys • Review relevant literature • Cross-check with other surveys • Focus groups with audience members • Create online: SurveyMonkey or institutional ITC • Revise, revise, revise
Our “Map” Purpose: Guide & Evaluate Social Norms Alcohol Educational Interventions of OHP/CASE Is there change? Who changed? Where is exposure the greatest? Critical data for quant. analysis INDIVIDUAL CHANGE OVER TIME Matching code (1) DEMOGRAPHICS 1 Gender 1 Ethnicity 1 Year 1 Age 1 International 1-4 Greek/Athlete 1-4 Family history (2) DRINKING BEHAVIORS & ATTITUDES Attitudes Behaviors Quantity Frequency BAC – weight Celebratory drinking (3) PERCEPTION OF DRINKING B&A - Attitudes -- Acceptable - Behaviors -- Quantity -- Frequency (4) EXPOSURE TO EDUCATION - Intervention frequency? Y/N? - List intervention -- SSJ -- G-wide -- ADAPT -- PHE -- AA… 2,3 (5) OUTCOME MEASURES - Protect. Behaviors - Neg. Consequences Other comments… ?’s - Stages of change? - Most effective way to measure Q F - Reference Alcohol Wise & NCHA Don’t - Involvement - Leadership - Drugs/Tobacco - Drinking since winter break - Where drinking happens ? - 2nd hand effects - Others drinking NCHA - Fake ID
Some Social Norms Specific Issues • Perception questions: • “Typical student” or “Most students” • The “gap”: what do we need to know • Wording for injunctive norms: • “I believe that…” • “I think that most students believe that…”
Getting to Go • NIH Certificate of Confidentiality • IRB approval • VPSA approval • Sampling frame • Unexpected road blocks
Going, Going…GONE • Timing • Online • Response Rates • Incentives • Length of time it’s open • Reminders
