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.
