| Objective The purpose of the present study was to develop and evaluate the reliability ,validity and responsiveness of the Pregnant Women Nutrition Knowlegde,Attitude and Practice Questionnaire (PNKPAQ),to examine the status and influential factors of nutrition knowlegde,attitude and practice for pregnant women,to verify the empirical validity of PNKPAQ.Methods The original questionnaire was developed based on literature review,semi- structured interview,focus group discussion,etc;then modified by the results of the small-scale pilot study and expert evaluation;and then administered as a self-reported one to pregnant women in the second and third trimester.6 statistical methods,such as Pearson correlation analysis,maximum orthogonal rotation factor analysis,stepwise regression analysis,etc.were employed to select the items,with experts'comments acted as the final decision-making guidance.Cronbach'sαcoefficients,content validity,and construct validity were well tested.The test-retest validity was well examined using Pearson correlations during 7 to 12 days after the first surveyed.Pregnant women were selected from Hefei for the study,their spouse and primary diet caregiver during pregnancy were also admitted into the study.The questionnaire included the socio-demographic characteristics,the nutrition knowlegde,attitude and practice status of pregnant women,spouse and Diet caregivers,the Social support status, etc. Descriptive statistics,Pearson correlation analysis,Analysis of variance,Students't-test,Stepwise regression analysis,etc were employed to analyze the status and correlation of nutrition knowlegde,attitude and practice, social support,and influence factors of nutrition KAP for pregnant women in the second and third trimester.Results According to the statistical analysis and experts'comments,the selected questionnaire with 3 dimensions and 47 items was eventually formed.The test-retest reliability coefficient and Cronbach'sαcoefficient were 0.86 and 0.76, respectively; The CVI of the questionnaire and the items were greater than 80%, the correlation coeff -icients between nutrition knowledge,attitudes,behavior and the total questionnaire score were greater than 0.6,in which the correlation between nutrition knowledge and KAP was the most strong,the correlation coefficient r= 0.898;Confirmatory factor analysis showed a questionnaire structure identical to the previous design.Of 535 pregnant women,nutrition KAP score was 9 ~ 44 (31.36±5.24),passing rate was 73.10%,nutrition attitude was generally good,but there were problems in cognition, food intake frequency and other nutrition behavior;the social support level of pregnant women is higher than average and the difference was statistically significant (P < 0.05); Pregnancy nutrition knowledge,attitude and behavior was significantly positively related,nutrition KAP and objective support,support for the use,total social support were were significantly positively related;nutrition knowledge,attitude,behavior and KAP of pregnant women and spouse,diet caregivers were significantly positively related,respectively;Nutrition KAP was affected by their own education,objective support,nutrition knowledge of dief caregivers;the Cronbach'sαcoefficients of PNKPAQ in this survey was 0.825,verifying its good internal consistency.Conclusion After the strict item selection,the development of the Pregnant Women Nutrition Knowlegde,Attitude and Practice Questionnaire (PNKPAQ) has been preliminary completed.It consists of 3 dimensions and 47 items,which has got a good empirical validity,can act as an effective tool for assessing the nutrition status of pregnant women.Nutrition KAP of pregnant women was good,it was affected by their own education,objective support,nutrition knowledge of diet caregivers.We should take different measures to different backgroud people,and expand to the scope of other family members,giving full play the role of social support,to improve effectively the nutrition of pregnant women.
