Area of Science:

  • Health Psychology
  • Decision Science
  • Medical Sociology

Background:

  • Patient involvement in healthcare decisions is increasing.
  • This trend may lead to a rise in decision regret.
  • No validated tool existed to measure post-decision regret in healthcare.

Purpose of the Study:

  • To develop and validate a reliable scale for measuring regret after health care decisions.
  • To assess the scale's psychometric properties, including internal consistency and convergent validity.

Main Methods:

  • A 5-item scale was administered to 4 distinct patient groups making various healthcare decisions.
  • Convergent validity was assessed by correlating the scale with measures of satisfaction, decisional conflict, and health outcomes.

Main Results:

  • The scale demonstrated strong internal consistency (Cronbach's alpha = 0.81–0.92).
  • Significant correlations were found with decision satisfaction (r = -0.40 to -0.60), decisional conflict (r = 0.31 to 0.52), and quality of life (r = -0.25 to -0.27).
  • Patients who changed their decisions reported significantly greater regret than those who did not.

Conclusions:

  • The developed 5-item scale is a valid and reliable measure of health care decision regret.
  • The scale provides a useful indicator of regret at a specific point in time, supporting its use in clinical and research settings.
