Methods Psychometric properties of single-item and dual answer multiitem scales were assessed, as well as methods to evaluate thresholds of meaning. Results Test-retest reliability and construct validity of single item global measures was moderate to good. The value of measuring both degree of difficulty and amount of time with difficulty in multiitems questionnaires was confirmed. Thresholds of meaning vary depending on methods and external anchors applied. Conclusion We have advanced our understanding of the performance of presenteeism measures and have developed approaches to describing thresholds of meaning. ER -
