Turkish Version of the Cardiac Distress Inventory and Cardiac Distress Inventory Short Form: A Validity and...

Area of Science:

• Psychometrics
• Cardiology
• Mental Health

Background:

• Negative moods like anxiety and depression impair lifestyle adherence post-cardiac event.
• Screening for cardiac distress and timely referrals are vital for patient recovery.
• The Cardiac Distress Inventory (CDI) assesses psychological and emotional states in cardiac patients.

Purpose of the Study:

• To evaluate the validity and reliability of the original Cardiac Distress Inventory (CDI) and its short form (CDI-SF) in Turkish.
• To determine the suitability of the CDI and CDI-SF for assessing psychological distress in a Turkish cardiac patient population.

Main Methods:

• Administered the CDI and CDI-SF to 417 acute coronary syndrome patients in Turkey.
• Assessed validity using Exploratory Factor Analysis (EFA), Rasch, and Confirmatory Factor Analysis (CFA).
• Evaluated reliability using McDonald's Omega (ω), Pearson correlation, and Receiver Operating Characteristic (ROC) analysis.

Main Results:

• The original CDI's factor structure and fit indices were not confirmed for the Turkish population.
• The CDI-SF demonstrated strong construct validity and internal consistency, suitable for unidimensional use.
• High reliability was observed for both CDI forms, but only the CDI-SF showed adequate psychometric properties for Turkish patients.

Conclusions:

• The Cardiac Distress Inventory short form (CDI-SF) is a valid, reliable, and pragmatic screening tool for cardiac distress in common heart diseases.
• The CDI-SF exhibits strong psychometric properties, making it effective for clinical management of cardiac patients in Turkey.
• The CDI-SF is recommended for use by clinicians and researchers for assessing psychological distress in cardiac populations.
