Lifestyle plays an important role in determining health and vitality among older adults. However, there is limited evidence regarding lifestyle assessment. This study examined the psychometric properties of the Yonsei Lifestyle Profile-Satisfaction (YLP-S). The participants in the study included 156 older adults. Rasch analysis was used to test unidimensionality, fit statistics, and the precision of the YLP-S. The YLP-S demonstrated a unidimensional measurement construct, and 18 items fit the Rasch model. The YLP-S illustrated reasonable precision (person strata = 5.37). Only 4 items showed differential item functioning by sex or age groups. The findings indicate that the YLP-S demonstrated sound internal validity and can be used by health professionals to measure the multifaceted lifestyle of older adults.

This paper details the development and validation of a listening self-efficacy instrument for EFL/ESL learners with beginner- to-intermediate-level English language proficiency. Self-efficacy, or the belief in one's ability to perform a task successfully, is believed to determine how likely individuals will be to cope with difficulties relating to the task domain (e.g., listening, speaking, reading, or writing), and to sustain their effort in spite of obstacles (Bandura, 1997). To date, few instruments have been developed to evaluate English L2 listening self-efficacy. The instrument presented here was distributed among a sample of first- and second-year Japanese university students (N = 121), and, unlike most previously developed questionnaires, was validated through the use of Rasch analysis. The results of the administration of the questionnaire showed that learners' responses differed predictably and considerably, thereby suggesting the utility of the instrument for future use by EFL/ESL practitioners.
