Abstract
Efficacy of Behaviour Modification Techniques in a case of vomiting. This article describes the design and subsequent step-by-step application of an intervention program based on behaviour modification techniques, to a case of vomiting without known organic causes. The results obtained from the pre-treatment evaluation showed the physical svmptoms to be the consequence of several psychological variables: disfunctional thinking; lack of behavioural resources to deal with certain social situations (speaking in public, expressing disagreement and handling criticism). The treatment, based on the data obtained by functional analysis and taking into account the variables specific to this case, consisted of: cognitive reestructuring, assertiveness training, handling criticism and covert assertion. The pre-determined therapeutic goals were achieved after 15 sessions and had still been maintained at the three, six and twelve month follow-ups.
