The responsiveness of the Individual Work Performance Questionnaire (IWPQ) was assessed. While most correlations were in the expected direction, weaker-than-anticipated results limit firm conclusions about the IWPQ
Area of Science:
- Occupational health and performance psychology.
- Workplace well-being and productivity research.
Background:
- Individual work performance is crucial but challenging to measure.
- The Individual Work Performance Questionnaire (IWPQ) was developed to address limitations in existing scales.
- This study aimed to evaluate the responsiveness of the IWPQ.
Purpose of the Study:
- To assess the responsiveness of the Individual Work Performance Questionnaire (IWPQ).
- To examine correlations between changes in IWPQ scores and related constructs.
Main Methods:
- Utilized data from the Be Active & Relax randomized controlled trial.
- Individual work performance was a secondary outcome.
- 39 hypotheses tested correlations between IWPQ changes and other measures (e.g., presenteeism, need for recovery).
Main Results:
- 260 participants completed the IWPQ at baseline and 12-month follow-up.
- 23% to 38% of hypotheses were confirmed.
- Correlations between change scores were generally weaker than expected, though 85% were in the predicted direction.
Conclusions:
- Firm conclusions on IWPQ responsiveness could not be drawn due to weaker-than-expected correlations.
- Further research with populations and interventions expected to yield greater changes is recommended.
- Future studies should explore IWPQ responsiveness in diverse settings.
