Autonomy-supportive decision-making in maternity care during prenatal consultations: a qualitative interaction analysis.

The results of this study show that the model of ASC can be enriched by adding minimising language and humour to the mechanisms that can be used to fulfil the psychological need 'relatedness'. Second, our results show that professionals use only few mechanisms to meet the patients' psychological needs 'competence' and 'autonomy'. They mainly use information giving to meet patients' need competence. To meet patients' need for autonomy, the professionals keep all options open. This suggests that professionals could pay more attention to other mechanisms to meet patients' needs for 'competence' and 'autonomy'.
