A six-day workshop was conducted to develop trainers in mental health by providing physicians participating in the programme with the necessary educational knowledge and skills. A significant improvement was observed in the participants' knowledge and skills after the workshop. A significant correlation was found between the increase in knowledge and that of performance. The increase was affected neither by the years of work experience nor by the postgraduate degree held. This observed benefit and the satisfaction expressed by participants encourage the replication of such a programme in order to develop qualified health personnel capable of expanding mental health services for children.
