Abstract:
Objective To develop anxiety scale suitable for Chinese pregnant women and evaluate its reliability and validity. Methods Based on existing research results and clinical experience,this study compiled pregnancy anxiety scale(PAS). A sample of 509 pregnant women were selected for investigation and 65 of them were randomly retested for test-retest reliability with 2 week interval. Item analysis was con-ducted to screen valid items. Then the construct validity of the scale was tested by exploratory factor analysis ( EFA) and confirmatory factor analysis(CFA). Finally the reliability and criterion validity of the scale were evaluated using Cronbach's α coefficient,retest reliability coefficient and Pearson correlation coefficient. Re-sults The PAS was composed of 27 items in four factors,including worry about delivery,worry about them-selves,worry about fetal health and general anxiety. The four factors were extracted by EFA which could ex-plain 62. 48% of the total variance. Besides,the result of CFA demonstrated that the model fitted the data with well construct validity (χ2/df=1. 89,RMR=0. 04,RMSEA=0. 06,IFI=0. 92,TLI=0. 91,CFI=0. 92, PGFI=0. 70,PNFI=0. 74,PCFI=0. 81). The score of the pregnancy-related anxiety scale and its factors scores were positively correlated with the scores of pregnancy-related anxiety questionnaire(PAQ) and child-birth attitudes questionnaire(CAQ). The correlation coefficients were 0. 60-0. 80 and 0. 50-0. 78 respectively (all P<0. 01). The Cronbach's α coefficient was 0. 93 for the total scale and that of the four factors ranged from 0. 82 to 0. 90. The test-retest reliability was 0. 68 for the total scale and ranged from 0. 54 to 0. 75 for the four factors. Conclusion The PAS has a good reliability and validity,and it can be used as a valid tool to measure the anxiety level of pregnant women.
