Pediatric anesthesia & critical care
Development of the Japanese Version of the Modified Yale Preoperative Anxiety Scale (mYPAS) in Pediatric Anesthesia: A Pilot Study for Psychometric Evaluation
Authors' conclusion
The Japanese version of the scale was successfully developed, and pilot findings indicated its feasibility in Japanese clinical settings
Study context
- Population
- Children aged 5–12 years undergoing elective surgery under GA
- Participants
- 15 children
- Outcome
- Feasibility, psychometric properties (reliability: internal consistency, inter-rater, intra-rater; concurrent validity vs STAIC) and sample size requirements
Methodological detailstranslation and cultural adaptation (ISPOR Task Force Guidelines)
- Translation and cultural adaptation (ISPOR Task Force Guidelines)
Performance
As reported in the abstract
Psychometric properties of the Japanese version
Internal consistency (Cronbach's α), high
0.954
Inter-rater reliability (weighted Kappa), moderate-to-very-good
0.42-0.92
Intra-rater reliability (intraclass correlation coefficient), excellent
0.86-0.97
Correlation with STAIC-State (rs), poor
−0.20 to −0.01
Further findings
Sample size required for future reliability studies (Walter's formula)
- Patients required
- 99
