title: The use of preventive health care services: carrier testing for the genetic disorder haemophilia.
abstract: A retrospective study was performed to explore carrier testing among women who were possible or obligate carriers of the haemophilia gene. Knowledge of the possibility of carrier testing and use of carrier testing were studied separately. In our exploration we were guided by the diffusion theory and the Health Belief Model. Logistic regression analysis showed that four factors were statistically significant related to knowledge of carrier testing: information via mass media, a haemophilic relative in the nuclear family rather than in the extended family, medical severity of haemophilia, and information from the patients' organization. For those women acquainted with carrier testing two of the four factors just mentioned were significantly related to the utilization of carrier testing i.e. having a haemophilic relative in the nuclear family and the medical severity of the haemophilia. In addition the following factors were associated: attitude towards abortion because of haemophilia, educational level, and marital status. Notwithstanding the prominent function of the mass media and the patients' organization, the respondents themselves stated that relatives, especially parents and sisters, were the most important source of information on genetic counselling and carrier testing.
