Abstract

Objectives: EASY-Care Standard 2010 questionnaire is a patient-centered tool for comprehensive assessment of the elderly. The objective of this paper is to determine the underlying structures among the items in the questionnaire, in elderly people attending a Malaysian primary care clinic

Methods: Face and content validity of the EASY- Care questionnaire were first assessed by an expert panel and patients. Elderly patients aged > 60 years attending a primary care clinic in Kuala Lumpur were approached for study and 337 patients consented. The questionnaire was self- administered. The exploratory factor analysis in SPSS version 15 was used to determine the underlying structures in the EASY-Care questionnaire.

Results: In the final model, the Kaiser-Meyer-Olkin value was 0.807, which is considered to be very good. Six factors were extracted that explained 71% of the total variance of the items in the model. After rotation, all the factor loading were seen to be 0.6 and above. The average variance extraction for the six factors were 59.9%, 47.0%, 67.4%, 62.8%, 54.9% and 58.3%, respectively and the composite reliability values were 0.960, 0.888, 0.892, 0.871, 0.828 and 0.843. The six factors were named as: Mobility (4 items), ADL (3 items), Cognitive Functioning (2 items), Communication (2 items), Continence (2 items) and Sensory (2 items).

Conclusion: The items in each of the six underlying dimensions seem to measure the respective concepts adequately. The 15-item questionnaire can be a simpler version for EASY-Care.
