title: [German translation and adaptation of the uncertainty stress scale high risk pregnancy version III (USS-HRPV) for hospitalised women with high-risk pregnancy].
abstract: BACKGROUND
  A number of medical and societal factors currently contribute to an increasing number of women who are hospitalised because they are experiencing high-risk pregnancies. The unpredictability of the further course of pregnancy may lead to a feeling of uncertainty, as well as to stress, depending on coping strategies.
  
  
  OBJECTIVE
  The aims of this study were thus to translate and adapt the USS-HRPV so that uncertainty and stress could be systematically measured on affected women in German speaking areas.
  
  
  METHODS
  Translation of the scale was undertaken by first translating into German and then back into English. The two-phase adaptation, carried out with affected women (n = 24) and midwives (n = 10), comprised cognitive interviews and testing of content validity using the Content Validity Index (CVI). Following each data collection phase the instrument was modified with the help of midwifery experts (n = 3).
  
  
  RESULTS
  For each item the calculated CVI (I-CVI) in the first phase ranged between 0,10 and 1,0 for the sample of relevant women and midwives while the CVI of the total instrument (S-CVI/Ave) was 0,62 and 0,70 respectively. In the second phase the I-CVI values of the hospitalised women ranged between 0,17 and 1,0 while the S-CVI/Ave value was 0,73. With regard to all of the data, 44 of the original 86 items were removed and 28 altered on language grounds.
  
  
  CONCLUSIONS
  As a result of the methodical approach utilised, a firm basis for further validation of the instrument for German speaking areas has been provided.
