title: Psychometric properties of the Swedish version of the Self-Transcendence Scale among very old people.
abstract: OBJECTIVE
  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.
  
  
  CONCLUSIONS
  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.
