Learning Objective 1: know how to develop a psychometric instrument.

Learning Objective 2: apply the inventory to assess the adaptation status of the elders in nursing home

Purpose: The study aims to develop and evaluate a psychometric instrument which can be applied to assess adaptation status of the elders in nursing home.

Methods: A qualitative research method with adopted deep-interview was conducted to identify the dimensions of the elders’ adaptation status in nursing home, and the corresponding items were constructed as well.  Three gerontology nursing faculties and three clinicians addressed the content validity, language, clarity and simplicity of the inventory.  Then, the constructive validity was assessed by factor analysis with 108 samples.

Results: The resulting three-factor solution was determined by Eigen values greater than 1, and criterion selected for factor loadings was greater than 050.  In total, 69.8% of the variance was explained by this three-factor solution.  All 18 items had a significant loading on these three factors to correspond to three subscales.  Subscale 1, labeled Feeling of Self-Worth, consists of seven items; Subscale 2, labeled Feeling of Being Belonging to, consists of six items; Subscale 3, labeled Feeling of Being Continuous, consists of five items.  Cronbach’s alpha of internal consistency was 0.94, 0.91 and 0.84 for each subscale respectively.  Correlation of inter-rater reliability for content validity was 0.98.  A negative correlation (r=0.59, p=.000) was found between this inventory and Geriatric Depression scale.

Conclusion: The inventory derived from ground data provides an efficient scale for clinical application to assess and evaluate the elders’ adaptation status.  Thus, a quality care intervention for the elders can be provided as such.
