Psychometric Properties of the Swedish Version of the Self-Transcendence Scale Among Very Old People
Background and Purpose: This study tested the psychometric properties of a Swedish version of the Self-Transcendence Scale (STS). Methods: Cohen's weighted kappa, agreement, absolute reliability, relative reliability, and internal consistency were calculated, and the underlying structure of the STS was established by exploratory factor analysis. There were 2 samples available: 1 including 194 people aged 85–103 years and a convenience sample of 60 people aged 21–69 years. Results: Weighted kappa values ranged from .40 to .89. The intraclass correlation coefficient for the original STS was .763, and the least significant change between repeated tests was 6.25 points. Conclusion: The revised STS was found to have satisfactory psychometric properties, and 2 of the 4 underlying dimensions in Reed's self-transcendence theory were supported.
