Children's Perioperative Multidimensional Anxiety Scale (CPMAS): Turkish Validity and Reliability Study

Abstract

PurposeTo test the validity and reliability of the Turkish version of the Children's Perioperative Multidimensional Anxiety Scale (CPMAS). DesignMethodological research model. MethodsOne hundred children (81% male) aged 7 to 13 years undergoing elective surgery at a tertiary university hospital were included. Self-administered CPMAS and State-Trait Anxiety Inventory-Children were used to collect data at preoperative, operation day, and a month after the operation. Internal consistency, test-retest reliability, parallel form reliability, and content and construct validity of the tools were determined across all three visits. FindingsThe CPMAS demonstrated good test-retest reliability (ICC = 0.51 to 0.78) and good internal consistency (Cronbach's alpha = 0.78 to 0.81). Inter item correlation values were ranged from 0.20 to 0.62 at preoperative, 0.32 to 0.64 on the day of operation and 0.36 to 0.75 at a month after the operation. CPMAS single-factor construct and the explanatory percentages were 0.54 and above. After Pearson correlation analysis, CPMAS was moderately correlated with State-Trait Anxiety Inventory-Children at T1 (r = 0.54, P < .01) and T2 (r = 0.56, P < .01). ConclusionsThe Turkish version of CPMAS has good reliability and validity score. Therefore, it is a suitable instrument to assess perioperative anxiety in 7 to 13 years old children in a clinical setting.
