Exploratory and confirmatory factor analysis of the decision regret scale in recipients of internal cardioverter...

Area of Science:

• Cardiology
• Medical Psychology
• Health Services Research

Background:

• Decision regret is a significant factor influencing patient satisfaction and outcomes.
• The internal cardioverter defibrillator (ICD) is a critical intervention for cardiac patients, involving complex treatment decisions.

Purpose of the Study:

• To establish the psychometric properties of the Decision Regret Scale (DRS) in patients who received an ICD.
• To validate the DRS as a reliable and accurate measure of decision regret.

Main Methods:

• Cross-sectional study with 109 cardiac patients undergoing ICD implantation.
• Utilized exploratory and confirmatory factor analyses.
• Assessed internal reliability (Cronbach's alpha = .86) and discriminant validity.

Main Results:

• The DRS demonstrated strong internal reliability (alpha = .86).
• Factor analyses supported the construct validity of the DRS.
• The scale proved to be a reliable and valid measure for assessing decision regret in ICD recipients.

Conclusions:

• The Decision Regret Scale (DRS) is a psychometrically sound instrument for evaluating decision regret in ICD recipients.
• The DRS has practical implications for clinicians and researchers aiming to improve patient decision-making and outcomes.
• Further validation in diverse ICD patient populations is recommended.
