3. In 1993, I compiled all the information available on the subject, and attempted to relate it to a Portuguese cultural and scientific context in a study presented at the Faculty of Psychology and Sciences of Education, University of Coimbra. This study was entitled 'VIDEO-HOMETRAINING: Exploration of a New Method of Family Intervention for Pedagogical and Relational Problems', and was done as part of the subject 'The Family and the Education Process' of the Masters course, supervised by Drs. Ana Paula Relvas at University of Coimbra and at Coimbra and Dr L.T. Van Der Linden at the University of Amsterdam. In the first semester of that year, I collected all possible materials, studying the literature available and requesting copies of the most recent studies done in Holland. This included information about family intervention in general, the use of video in psychological intervention, and VIDEO-HOMETRAINING in particular. I also contacted the institutions that would be involved in the practical application, and obtained a sample of accompanied children from allergy clinics at the Paediatric Hospital, aged between 7 and 12, who were living with their parents in the district of Coimbra. The second semester was spent in Holland, witnessing the V.H.T. method in action. I participated in all the stages of intervention, in the training of the people who administered the intervention, and in the administration.
