Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Change in subjective stress and anxiety levels between T1 (baseline) and T2 (immediately before induction of anesthesia), measured using validated scales (VAS for stress and, where applicable, APAIS for anxiety), and compared across the three study groups (control group vs. intervention group A vs. intervention group B). | — |
Secondary
| Measure | Time frame |
|---|---|
| Comparison of the effect sizes of the two interventions (cognitive distraction booklet vs. Perplexus®) with regard to reductions in preoperative stress and anxiety. Patient-reported acceptability and perceived usefulness of the interventions, assessed on the first postoperative day (T3). Feasibility and practicality of the interventions in routine clinical care, including usability, duration of use, and required staff involvement. Evaluation of design and content characteristics of the interventions, with particular focus on the cognitive distraction booklet. Descriptive analysis of study drop-outs and the reasons for discontinuation or non-completion. | — |
