Objective To design perinatal grief scale ( PGS) for single intrauterine fetal death( sIUFD) and evaluate its reliability and validity, so as to provide reference for psychological nursing of this kind of pregnant women. Methods Scale development study group was established, with the PGS as a framework, 24 items were enrolled after brainstorming, expert consultation and preliminary experiments. From January 2013 to December 2015, 100 pregnant women with sIUFD were enrolled from this hospital. Internal consistency reliability, retest reliability, content validity, and receiver operating characteristic curve ( ROC) were used to analyze the sensitivity, specificity, etc. Results Cronbach′s α coefficient and split-half reliability of the scale were 0. 896 and 0. 806. Test-retest reliability and content validity index were 0. 901 and 0. 92. Except for the fifteenth item,the other items had a good correlation with total score (r = -0. 263 -0. 779). With PGS as calibration, PGS of sIUFD had a good correlation with PGS (r =0. 845, P <0. 001). The sensitivity and specificity of PGS of sIUFD were 0. 71 and 0. 72. The cut-off value was 72 points. Conclusions The PGS of sIUFD has good reliability, validity and sensitivity. It has an important clinical value on assessing the sad mood of sIUFD.
