TIPS Research Methods & Evidence-Based Practice 3

Question 1

A TIPS program evaluation finds a statistically significant reduction in over-service incidents after training. What does 'statistically significant' mean in this context?

Accepted Answer

The result is unlikely to be due to chance alone

Answer

Statistical significance means the observed result would rarely occur by chance under the null hypothesis, typically indicated by a p-value below a predetermined threshold such as 0.05.

Question 2

Which type of bias is most likely to affect a study where TIPS-trained servers self-report their own compliance with responsible beverage service guidelines?

Accepted Answer

Social desirability bias

Answer

Social desirability bias occurs when respondents answer in ways they believe are viewed favorably rather than truthfully, a common issue in self-reported compliance studies.

Question 3

TIPS relies on evidence that alcohol affects judgment before motor coordination. Which area of the brain is primarily responsible for judgment and impulse control?

Accepted Answer

Prefrontal cortex

Answer

The prefrontal cortex governs executive functions including judgment, decision-making, and impulse control, and is highly sensitive to alcohol even at low BAC levels.

Question 4

A meta-analysis of server intervention studies shows an overall effect size of d=0.35. How should a TIPS trainer interpret this finding?

Accepted Answer

Server training produced a small but meaningful positive effect across studies

Answer

Cohen's d of 0.35 is generally considered a small-to-medium effect size, indicating a modest but real benefit of server training programs aggregated across multiple studies.

Question 5

When TIPS training materials cite research, they prioritize peer-reviewed studies over news articles primarily because peer review:

Accepted Answer

Subjects the research to independent expert scrutiny before publication

Answer

Peer review requires independent experts to evaluate a study's methodology and conclusions before publication, increasing the credibility and rigor of the research.
