Abstract：Objective To develop and evaluate the validity and reliability of the Demands Scale of Women of Advanced Maternal Age during Their Second Pregnancy（DSWAMATSP）．Methods From July to December 2016，convenience sampling was employed to recruit 260 women of advanced maternal age during their second pregnancy who underwent antenatal examination at the outpatient department of a tertiary grade A hospital in Yancheng，China.Based on Maslow's hierarchy of needs，results of the interviews of these women and Delphi expert consultation，we developed the initial DSWAMATSP.Critical value and correlation coefficient were adopted to choose suited items.Cronbach's α was adopted to evaluate the reliability of the scale，and content validity and exploratory factor analysis were conducted to evaluate the validity of the scale.Results The initial scale consisted of 7 dimensions and 57 items.Nine items were deleted based on the results of Delphi expert consultation and 3 items whose item-to-dimension correlation coefficients were less than 0.400 were excluded.The final scale contains 45 items in 7 fields.The Cronbach's α was 0.933 for the total scale and 0.799 to 0.937 for its subscales.Factor analysis revealed 7 common factors，accounting for 64.08% of the total variance，loading for each factor was over 0.400.The content validity index was 0.866 for the total scale.Conclusion The DSWAMATSP is reliable and can be used as a tool for evaluating the needs of women of advanced maternal age during their second pregnancy.
