Abstract
PURPOSE
To develop and psychometrically evaluate the Psychological Adaptation to Genetic Information Scale (PAGIS).
DESIGN
A cross-sectional, Web-based survey of participants (n=323) recruited via Internet electronic mailing lists or Websites for people affected by genetic diseases.
METHODS
Item analysis, confirmatory principal components analysis, and internal consistency reliability using Cronbach's alpha were used to construct the 26-item PAGIS.
FINDINGS
Five factors (nonintrusiveness, support, self-worth, certainty, and self-efficacy) explained 57.7% of the variance in psychological adaptation to genetic information. The internal consistency reliability of the total PAGIS was .90, and the subscale reliabilities ranged from .77 to .87.
CONCLUSIONS
Psychological adaptation to genetic information is a multidimensional phenomenon comprised of nonintrusiveness, support, self-worth, certainty, and self-efficacy. The PAGIS has initial reliability and validity for use in future research.
