A regional health authority conducted a study across corporate workplaces to evaluate the impact of mandatory 15-minute guided mindfulness breaks introduced twice daily. Over a six-month trial, participating companies reported a 25% decrease in formal employee sick leave requests. Based on this outcome, the health authority concluded that the mindfulness breaks directly improved employee physical health and reduced illness incidence. Analysts and independent researchers provided four statements regarding these results.
Match each analytical statement with the precise logical role it plays in evaluating the health authority's causal argument.
- Employees who participated in the breaks also voluntarily engaged in higher rates of personal exercise prior to and throughout the study period than non-participating control groups.Selection Bias / Pre-existing Confounder: Demonstrates that observed differences stem from baseline participant characteristics rather than the intervention.
- During the exact six-month trial period, participating companies also introduced a new remote-work policy allowing employees to work from home when feeling mildly unwell.Alternative Causal Explanation: Introduces a simultaneous external factor that independently accounts for the decrease in sick leave.
- The reduction in sick leave requests occurred predominantly among employees reporting high baseline work stress, whereas sick leave rates remained unchanged in non-participating control companies operating under identical baseline conditions.Strengthening Evidence: Supports the causal claim by showing the expected effect pattern concentrated in the target group alongside control validation.
- Employees reported avoiding formal sick leave submissions because they mistakenly believed doing so would forfeit annual wellness bonuses tied to program attendance.Measurement Artifact / Reporting Incentive Shift: Shows that the change reflects how data was recorded rather than an actual improvement in physical health.
Cevap
Each analytical statement correctly matches its respective logical role in causal argument evaluation: baseline exercise differences represent Selection Bias / Pre-existing Confounder; the new remote-work policy represents an Alternative Causal Explanation; concentrated stress-reduction with control validation represents Strengthening Evidence; and fear of losing bonuses represents a Measurement Artifact / Reporting Incentive Shift.
The correct pairings accurately classify each statement according to standard critical reasoning principles: pre-existing habit differences indicate selection bias; concurrent operational changes represent alternative explanations; controlled subgroup variance provides strengthening support; and metric distortion due to incentive perception represents a measurement artifact.
