Abstract
OBJECTIVE: Childhood depression has become a serious concern in recent years. Therefore, it is important for healthcare professionals to have a reliable instrument for measuring depressive symptoms adapted to their culture and language. The Children's Depression Inventory 2 (CDI-2) is a tool that has been widely used in many countries. The present study aimed to investigate the internal consistency reliability and construct validity of the full-length 28-item Greek-Cypriot version of the CDI-2: Self Report (CDI-2:SR) among schoolchildren in Cyprus. METHODS: A methodological instrument validation design was performed between 2020 and 2023 on a nationwide random sample of schoolchildren in Cyprus recruited from public elementary schools. A total of 420 Cypriot children aged 11-13 years were included in the study. Internal consistency was determined, and factor analysis was performed to examine the psychometric properties of the CDI-2:SR. RESULTS: The internal consistency of the CDI-2:SR was adequate. In addition, factor analysis indicated a two-factor solution, with the first factor reflecting social-emotional problems and the second factor representing cognitive-behavioral problems. CONCLUSIONS: The Greek Cypriot version of the instrument appeared to be satisfactory in terms of reliability and validity for screening depressive symptoms in children.
