5. In my master’s dissertation there is a chapter about the V.H.T. method, which begins with a review of the authors who provide a theoretical background for the method. Firstly I examine the framework proposed by Schepers (1994), which relates aspects of human ethology with different aspects of communication science, and science of education with different areas of psychology; references are also made to other authors considered relevant. Then I proceed to a theoretical contextualization, which begins with aspects of communication pragmatics (Watzlawick, 1967), and covers examples of family communication (Lange, 1983; Kelley, 1983 and Hawkins, 1988), characteristics of parent-child relationships (Threvarthen, 1989; Schaffer, 1984 and Schaefer, 1980), and parent-child relational disorders (Schaffer 1977, and Paixão, 1988). Finally I look at attempts to approach these aspects by means of video (Dowrick 1991 and Threvarthen 1989), and the importance of working with parents is broached. There follows an analysis of the socio-political context that gave rise to the V.H.T. method in Holland, which is integrated into the regional, mobile intervention programme HOMETRAINING. The methodology itself is described: its origin, organization and institutions involved; adoption within the country and abroad, both quantitatively (number of regions and professionals involved) and qualitatively (target population and flexibility of aims); staff training; application criteria; therapeutic, pedagogical, social and economic objectives; and its practice: basic assumptions, directives, charts (for the analysis of basic communication), and procedure (which takes place in four stages, namely evaluating the reason for referral, taking the decision, the intervention itself and follow-up). Finally I weigh up the advantages and disadvantages of the application from a cultural perspective. At the end I draw some general conclusions about the method, in the form of topics surveyed in the literature on VHT, and in some theoretical references referred to in the conceptual framework. I also comment on the advantages of using video in this area of work.
