Validity and Reliability of Patient Activation Measure (PAM13-I) Italian Version Among Patient Undergoing Elective...

Area of Science:

• Health Psychology
• Medical Sociology
• Patient-Reported Outcomes

Background:

• Patient activation is crucial for effective healthcare management.
• The Patient Activation Measure (PAM) is a globally recognized tool for assessing patient engagement.
• Validating PAM in diverse populations, including surgical patients, is essential.

Purpose of the Study:

• To evaluate the psychometric properties and construct validity of the Italian 13-item Patient Activation Measure (PAM13-I).
• To assess the reliability and applicability of PAM13-I in patients undergoing elective laparoscopic cholecystectomy in Italy.

Main Methods:

• A multicenter study involving 4532 patients across 111 Italian surgical units.
• Preoperative administration of the PAM13-I questionnaire.
• Rasch analysis was employed to evaluate psychometric properties, including internal consistency, reliability, item functioning, and targeting.

Main Results:

• The PAM13-I demonstrated strong internal consistency (Cronbach's α = 0.95) and acceptable reliability.
• Rasch analysis indicated acceptable fit statistics but revealed ceiling effects.
• No significant differential item functioning was detected, though targeting and local response dependency issues were noted.

Conclusions:

• The Italian PAM-13 exhibits promising psychometric properties for assessing patient activation in surgical settings.
• Observed ceiling effects and targeting concerns necessitate further refinement and validation in surgical populations.
• The PAM13-I holds potential utility for understanding and enhancing patient engagement in elective surgery care.
