We started with a general questionnaire, the WHOQOL-BREF (its use has been approved by the author of the Czech version [27]). We decided on the World Health
Organization Quality of Life generic questionnaire due to our concern with physiological pregnancy, i.e. with the population of healthy women. Moreover, this questionnaire
[3] is the most commonly used generic instrument for assessing the quality of life in pregnancy. WHOQOL-BREF contains a total of 26 items grouped into four domains and
two separate items evaluating the overall quality of life (Q1) and satisfaction with one’s state of health (Q2). The results are expressed in terms of four domain scores
and mean raw scores of two separate items: D1- Physical (7 items), D2 – Psychological (6 items), D3 - Social relations (3 items), D4 - Environment (8 items). The higher the score values, the better the quality of life. Based on the results of the pilot study we developed a specific questionnaire, the QOL-GRAV. This measure has been designed as a supplement to the WHOQOL-BREF. The questionnaire includes socio-demographic data relating to pregnancy and 12 five-point Lickert items associated with pregnancy that reflect the structure of the four domains of quality of life (physical, psychological, social relations and environment) of the WHOQOL-BREF. The accompanying commentaries, individual items and scaling anchors have the same form as in the WHOQOL-BREF. Some items of the QOL-GRAV are further supplemented by open-ended questions asking for more detailed specifications of changes during pregnancy and coping strategies. Items 27 and 30–32 relate to the first domain of the physical QoL, while the psychological domain is represented by items 28, 29, and 38. The domain of social relations is represented by items 36 and 37, and items 33 and 34 represent the domain of environment. Both questionnaires were filled in by pregnant women during the three trimesters. Data collection lasted from
March 2010 to August 2011. For statistical data analysis, procedures of descriptive and inductive statistics contained in the software pack-age SPSS version 18 were used. For the estimation of re-
liability we used Cronbach alpha estimates of internal consistency ranging from 0 to 1 with the arbitrary value of .7 used as the minimum satisfactory level of internal consistency for research purposes.
