Overview

A questionnaire that can measure disease severity from the patients perspective in patients with pectus excavatum already exists in English (Pectus Excavatum Evaluation Questionnaire; PEEQ). This questionnaire was recently translated into Dutch. Before this Dutch version can be used, it needs to be tested by a number of patients.

Data will be collected at three moments:

  1. Preoperatively: The PEEQ will be completed on paper during the outpatient clinic visit.
  2. Postoperatively: The PEEQ will be completed electronically 2 months post-surgery.
  3. Test-retest reliability: The PEEQ will be administered electronically at least two weeks after a previous assessment.

Eligibility

Inclusion Criteria:

  • Eligible participants will be pectus excavatum patients aged 12 to 18 years old who are scheduled for a Nuss procedure. Parents or legal guardians will also be invited to complete the parent section of the PEEQ.

Exclusion Criteria:

  • Exclusion criteria will be the inability of the patient or their parent/guardian to complete the corresponding section of the questionnaire due to language barriers.
