N2 - This study aimed to adapt and validate the Posttraumatic Growth Inventory in Chinese shidu parents (PTGI-CS) and to develop its short form (PTGI-CS-SF). A convenience sample of 899 participants across China was included in the analyses. Results of parallel analysis and confirmatory factor analysis suggested that a bifactor model (a general posttraumatic growth factor with three specific factors: philosophy of life, changes in self and relationships with others) of the PTGI-CS had an optimal fit (root mean square error of approximation =.065, comparative fit index =.927, Tucker-Lewis index =.902, standardized root mean squared residual =.054). The 17-item PTGI-CS had satisfactory convergent and discriminant validity, internal consistency (Cronbach’s alpha =.906) and test–retest reliability (r =.776, p <.01). However, omega hierarchical coefficients for three subscales were low (.202 to.391), which indicated that only the total scores of PTGI, and not the subscale scores, should be used. Additionally, a 9-item short form of PTGI-CS has been developed and was shown to be a reliable instrument to assess Chinese shidu parents’ PTG.
