Estimating the Reliability of Aggregated and Within-Person Centered Scores in Ecological Momentary Assessment
A procedure for estimating the reliability of test scores in the context of ecological momentary assessment (EMA) was proposed to take into account the characteristics of EMA measures. Two commonly used test scores in EMA were considered: the aggregated score (AGGS) and the within-person centered score (WPCS). Conceptually, AGGS and WPCS represent the interindividual differences and the intraindividual differences, respectively. The reliability c…
Social participation reduces depressive symptoms among older adults
These findings suggest that maintaining or initiating social participation in later life benefits the mental health of older adults. Facilitating social activities among older adults is a promising direction for programs intended to promote mental health and successful aging among older adults in Taiwan
Preliminary Study of a Scale Measuring Depression and Somatic Symptoms
This description concerns the development of a scale measuring depression and somatic symptoms and the selection of its items for a Taiwanese sample. 102 Taiwanese outpatients (28 men, 74 women) with major depressive disorder completed a 44-item preliminary scale. All had experienced a major depressive episode but had not been treated by antidepressants within the prior two weeks. The Hamilton Depression Rating Scale was administered to evaluate …
Parallel Analysis with Unidimensional Binary Data
The present simulation investigated the performance of parallel analysis for unidimensional binary data. Single-factor models with 8 and 20 indicators were examined, and sample size (50, 100, 200, 500, and 1,000), factor loading (.45, .70, and .90), response ratio on two categories (50/50, 60/40, 70/30, 80/20, and 90/10), and types of correlation coefficients (phi and tetrachoric correlations) were manipulated. The results indicated that parallel…
Impact of the Number of Response Categories and Anchor Labels on Coefficient Alpha and Test-Retest Reliability
A total of 1,247 college students participated in this study on the effect of scale format on the reliability of Likert-type rating scales. The number of response categories ranged from 3 to 9. Anchor labels on the scales were provided for each response option or for the end points only. The results indicated that the scales with fewresponse categories tended to result in lower reliability, especially lower test-retest reliability. The scales wit…
Effects of Response Order on Likert-Type Scales
The study investigated whether the change of response order in a Likert-type scale altered participant responses and scale characteristics. Response order is the order in which options of a Likert-type scale are offered. The sample included 490 college students and 368 junior high school students. Scale means with different response orders were compared. Structural equation modeling was used to test the invariance of interitem correlations, covar…
