Methods: The questionnaire was preliminarily developed by literature analysis, semi-structured interview and Delphi consulting method. Convenience sampling method was used and totally 257 caregivers of premature infants were recruited. The questionnaire was evaluated by item analysis, correlation analysis, exploratory factor analysis, content validity, structure validity, internal consistency reliability and split-half reliability. Results: The questionnaire with 55 items was preliminarily developed, and 15 items were deleted after questionnaire evaluation. Eight common factors were extracted by exploratory factor analysis, and the cumulative explanatory variation was 59.864%. The common factors extracted as questionnaire dimensions are parenting skills, role adaptation of parents, parent-child relationship, family function, positive coping, negative coping, support, health care knowledge of premature infants.The Croanbach's alpha was 0.916 for overall questionnaire and 0.724-0.906 for each dimension. The split-half reliability was 0.845 for overall questionnaire and 0.712-0.897 for each dimension. The content validity of the whole questionnaire (S-CVI) was 0.946, and the content validity (I-CVI) of each item was 0.824-1.000 with the corrected Kappa value 0.823-1.000. Conclusion: The questionnaire has good reliability and validity, which could be used as a tool to evaluate discharged premature infants' parents coping ability and to reflect the problems and confusion of parents to a certain extent, and to provide references for the formulation and evaluation of transitional care program for premature infants.
