The Children's Perioperative Multidimensional Anxiety Scale (CPMAS) effectively measures anxiety in children undergoing surgery. This validated tool shows good reliability and correlates with other anxiety measures, aiding in pediatric care.

Area of Science:

  • Pediatric Psychology
  • Anesthesiology
  • Child Psychiatry

Background:

  • Millions of children experience perioperative anxiety annually, leading to adverse outcomes.
  • Existing measures may not be suitable for busy clinical settings or young children.
  • A simple, age-appropriate tool is needed to assess pediatric perioperative anxiety.

Purpose of the Study:

  • To evaluate the psychometric properties of the Children's Perioperative Multidimensional Anxiety Scale (CPMAS).
  • To determine the reliability and validity of the CPMAS in children undergoing surgery.
  • To establish CPMAS as a useful clinical tool for pediatric perioperative anxiety.

Main Methods:

  • Eighty children (7-13 years) undergoing elective surgery completed the CPMAS and SCARED-C at three time points.

  • Psychometric properties assessed included internal consistency and test-retest reliability.
  • Convergent validity was examined by correlating CPMAS scores with SCARED-C scores.

    • Main Results:

    • The CPMAS demonstrated good internal consistency (Cronbach's alpha ≥ .80) and stability (ICC = 0.71).
    • CPMAS scores showed moderate correlations with SCARED-C total and state-related anxiety scores.
    • These findings indicate the CPMAS measures similar constructs to the SCARED-C.

    Conclusions:

    • The CPMAS is a reliable and valid self-report measure for pediatric perioperative anxiety.
    • The scale has potential as a valuable tool in clinical settings for children undergoing surgery.
    • Further use of CPMAS can improve the assessment and management of anxiety in pediatric surgical patients.
