TIPS Research Methods & Evidence-Based Practice 2 — Questions and Answers
Question 1: A TIPS-certified server notices that a patron who appeared sober 30 minutes ago is now showing signs of intoxication. Which evidence-based principle best explains this observation?
- Alcohol absorption can continue after drinking stops (Correct answer)
- The patron must have consumed alcohol elsewhere
- Behavioral signs are unreliable indicators of BAC
- Tolerance always prevents visible intoxication
Correct answer: Alcohol absorption can continue after drinking stops
Alcohol continues to be absorbed from the stomach and intestines after consumption ends, causing BAC to rise even when no new drinks are consumed.
Question 2: In TIPS training, which research-backed factor is identified as MOST likely to accelerate alcohol absorption?
- Drinking water between alcoholic beverages
- Consuming alcohol on an empty stomach (Correct answer)
- Choosing wine over spirits
- Drinking in a well-ventilated area
Correct answer: Consuming alcohol on an empty stomach
An empty stomach allows alcohol to pass directly into the small intestine for rapid absorption, significantly elevating BAC faster than when food is present.
Question 3: Which study design would provide the strongest evidence that a TIPS-based intervention program reduces alcohol-related traffic fatalities?
- A case report of one successful intervention
- A cross-sectional survey of bar patrons
- A randomized controlled trial comparing trained vs. untrained establishments (Correct answer)
- An expert opinion panel review
Correct answer: A randomized controlled trial comparing trained vs. untrained establishments
A randomized controlled trial is considered the gold standard because it minimizes bias through random assignment and allows direct comparison between groups.
Question 4: TIPS research demonstrates that server training programs are most effective when they include which component?
- Written exams only
- Passive lecture without role-play
- Behavioral rehearsal and role-playing scenarios (Correct answer)
- Online modules without in-person practice
Correct answer: Behavioral rehearsal and role-playing scenarios
Research consistently shows that behavioral rehearsal, such as role-playing refusal scenarios, significantly improves skill retention and real-world application by servers.
Question 5: A researcher wants to assess whether TIPS-certified bars have fewer drunk-driving incidents than non-certified bars. Which data source would be most objective?
- Self-reports from bar managers
- Police DUI arrest records near each establishment (Correct answer)
- Customer satisfaction surveys
- Server opinion questionnaires
Correct answer: Police DUI arrest records near each establishment
Official police DUI arrest records near each establishment provide objective, third-party data that is less susceptible to self-report bias than surveys from interested parties.
Question 6: According to evidence-based practice principles used in TIPS, what does 'construct validity' refer to in alcohol assessment tools?
- Whether the tool is easy to administer
- Whether the tool measures the concept it claims to measure (Correct answer)
- Whether the tool was designed by credentialed researchers
- Whether the tool produces consistent results over time
Correct answer: Whether the tool measures the concept it claims to measure
Construct validity refers to whether a measurement tool accurately captures the theoretical concept it is intended to measure, such as level of intoxication.
Question 7: In reviewing research on responsible beverage service, a TIPS trainer finds two studies with conflicting results. The best evidence-based step is to:
- Accept the older study as more established
- Choose the study with the larger sample size and higher methodological quality (Correct answer)
- Dismiss both studies and rely on personal experience
- Accept the study that supports current policy
Correct answer: Choose the study with the larger sample size and higher methodological quality
When studies conflict, evidence-based practice requires selecting the study with superior methodology and larger sample, as these factors reduce bias and increase reliability.
