To determine whether there is a difference in the extent to which the GP succeeds in establishing the reasons for consultation of Moroccans and those of the Dutch; and whether the opinion of Moroccans about the GP's consultation differs from that of the Dutch.Analysis of patient interviews and GP's consultations.In 11 general practices in Amsterdam and The Hague in May 1997, 50 Moroccan adults and 50 Dutch individuals were asked for their reasons to attend before the consultation and in the mother language; a distinction was made between the actual complaint and the expectations with regard to the consultation. The GPs recorded these data after every consultation. The complaints were coded by organ system and by nature of complaint, following which agreement of the assessments was scored on a scale ranging from 0 to 100.Both groups comprised 20 men and 30 women. The mean age of the Moroccans was 38.6 years (SD: 13.8), that of the Dutch 56.4 years (SD: 16.7). The GPs established complaints of Moroccan patients not as well as those of Dutch patients (score: 73.9 versus 87.3); the difference was more pronounced where patients with only elementary education were concerned (67.0 as against 86.1). The GPs were able to establish the expectations with regard to the consultation nearly as often for the Moroccan as for the Dutch patients (58.5 versus 55.9). Moreover, the Moroccans were as positive about the course of the consultation as the Dutch. Except for communication problems among the lower educated, none of the problems indicated appeared to be experienced more often by the Moroccans than by the Dutch.A large part of the complaints presented by lower educated Moroccan patients were interpreted differently by the GP. For Moroccans with a higher education, the care was comparable with that among the Dutch.
