Three samples of participants took part on it: Group 1: which comprises fifteen esthetic plastic surgery patients diagnosed as having BDD; Group 2: which includes fifteen esthetic plastic surgery patients diagnosed as not having BDD; Group 3: five professionals of psychiatry and psychology which stood as judges to evaluate the items of the scale. Initially, the items of the scale were generated from the study of 4 BDD evaluation questionaries which existed already, comtemplating the diagnostic criteria of the DSM-IV (1994) and of scientific assays on the BDD field. Fifty items were, then, built (1st version) which were evaluated by the authoress regarding relevance, objectivity, clearness and precision. From this analysis ten items were discarded, resulting in a 40-item scale (2st version). The relevance of the items to the construct by means of the theoretical analysis of judges. As a result from this analysis five more items were discarded for not obtaining an agreement of at least 80% among the judges (3sd version). The third version of the scale was applied on both groups (G1 and G2). The results from this aplication were submitted to the BDD construct study by means of factorial analysis. The discriminating validity was accomplised by the application of the 3sd scale version of the clinical population (G1) and of sample the non clinical population (G2). The estimate of the U Mann-Whitney Test showed that the scale is sensitive to distinguish the individuals diagnosed as having BDD from those diagnosed as not having the disorder. Besides, the instrument was applied once more twenty days later on both groups (G1 and G2), to submit the scale to the test-retest precision. Through the application of the Pearson Test one verified an expressive correlation between the first and the second application for group 1 as well as for group 2. As a result from these quantitative analyses no item was discarded for they showed to be relevant for the BDD measurement. It was, then, proposed a pilot version of the BDD diagnosis auxiliary instrument to be used by healthcare professionals. The current instrument consists of thirty five items measured by the four-point Likert scale. / A presente pesquisa teve por objetivo geral desenvolver e validar uma escala auxiliar de diagn?stico do Transtorno Dism?rfico Corporal (TDC) para profissionais da ?rea da sa?de. Para tanto contou com tr?s amostras de participantes: Grupo I: que englobou 15 pacientes de cirurgia pl?stica est?tica diagnosticados com TDC; Grupo 2: que incluiu 15 pacientes de cirurgia pl?stica est?tica sem o diagn?stico de TDC e; Grupo 3: 5 profissionais da ?rea de Psiquiatria e Psicologia que serviram como ju?zes para avaliar os itens da escala. Inicialmente os itens da escala foram gerados por meio do estudo de quatro question?rios de avalia??o do TDC j? existentes, contemplando os crit?rios diagn?sticos do DSM-IV (1994) e de trabalhos cient?ficos na ?rea do TDC. Construiu-se, ent?o, 50 itens (P Vers?o) os quais foram avaliados pela autora em rela??o a pertin?ncia, objetividade, clareza e precis?o. A partir desta an?lise foram descartados dez itens, o que resultou em uma escala de 40 itens (2a Vers?o). Analisou-se a pertin?ncia dos itens ao construto, por meio da an?lise te?rica de ju?zes. Como resultado desta an?lise mais cinco itens foram descartados por n?o obterem uma concord?ncia de no m?nimo 80% entre os ju?zes (3a Vers?o). A terceira vers?o da escala foi aplicada nos dois grupos (G1 e G2). Os resultados dessa aplica??o foram submetidos ao estudo do construto do TOC por meio da an?lise fatorial. A validade discriminativa foi realizada por meio da aplica??o da primeira vers?o da escala em uma amostra da popula??o cl?nica (G I) e uma amostra da popula??o n?o cl?nica (G2). O c?lculo da prova U de Mann-Whitney mostrou que a escala ? sens?vel para discriminar os indiv?duos diagnosticados com TDC dos indiv?duos sem o diagn?stico do transtorno. Al?m disso, o instrumento foi reaplicado ap?s 20 dias nos dois grupos (G1 e G2), para submeter a escala ? precis?o de teste-reteste. Atrav?s da aplica??o da correla??o de Pearson verificou-se uma alta correla??o entre a primeira e a segunda aplica??o tanto do Grupo 1 como do Grupo 2. Como resultado dessas an?lises quantitativas n?o foi descartado nenhum item pois os 35 mostraram ser significativos para a mensura??o do TDC. Foi proposta ent?o, uma vers?o piloto do instrumento auxiliar de diagn?stico do TDC para a utiliza??o por profissionais da ?rea da sa?de. O instrumento ficou composto por 35 itens medidos por escalas Likert de quatro pontos.
