ABSTRACT Purpose: The use of a different protocol to assess the same aspects of the Functional Communication Profile (FCP) may contribute to a faster and less expensive determination of individual profiles of abilities and inabilities. The purpose of this study was to verify the applicability of a checklist to replace the aforementioned complete protocol as a way to facilitate clinical and therapeutic follow-up processes. Methods: The participants in this study were 50 children aged from 3 to 12 years, with diagnoses within the autism spectrum who were receiving specialized speech-language therapy for at least six months. The participants were filmed while interacting with the speech-language pathologist, and the data were transcribed to the FCP protocol. After the recording and prior to the transcription, the speech-language pathologists were asked to answer the checklist of Communicative Functions. Results: All answers on the checklist and on the FCP were compared. The results indicated that there were statistical differences in nine of the 20 communicative functions, and in nine of the 50 children. These results suggest that the checklist is efficient to describe a group of children but not to characterize them individually. Therefore, it is possible to identify differences in the communicative profile but not to specify the frequency with which each function occurs. Conclusion: The checklist can be used as a tool in the therapeutic follow-up processes of children with autism spectrum disorders, but it does not replace the complete FCP protocol.

RESUMO Objetivo: A utilização de um protocolo que analise os mesmos aspectos que o Perfil Funcional da Comunicação (PFC) pode colaborar para a determinação de perfis individuais de habilidades e dificuldades de forma mais rápida e econômica. O objetivo deste estudo foi verificar a utilização de um checklist, em substituição ao protocolo completo, como elemento de facilitação do processo de acompanhamento clínico-terapêutico. Métodos: Participaram do estudo 50 crianças entre 3 e 12 anos, que têm diagnóstico incluído no espectro do autismo e recebem atendimento fonoaudiológico especializado há pelo menos seis meses. Os participantes foram filmados em situação de interação com o fonoaudiólogo e os dados, transcritos para o protocolo do PFC. Antes da análise, foi solicitado que as terapeutas respondessem ao checklist da Funcionalidade Comunicativa. Resultados: Todas as respostas do checklist e do PFC foram comparadas. Os resultados indicaram que, quando se compara a ocorrência de cada uma das funções, tem-se resultados diferentes em nove das 20 funções comunicativas e em nove das 50 crianças. Esses resultados indicam que o checklist mostra-se eficiente na descrição do grupo de crianças, mas não na caracterização individual. Assim, é possível identificar diferenças nos perfis pragmáticos, mas não especificar a frequência de ocorrência das funções. Conclusão: O checklist pode ser usado como instrumento de acompanhamento de processos terapêuticos de crianças com Distúrbios do Espectro do Autismo, mas não substitui o instrumento completo.

INTRODUCTION The importance of language in disorders within the autism spectrum is unique, because, contrary to other extensive development alterations in which language disorders are either symptoms or consequences of other deficits, language alterations in the autism spectrum correspond to one out of the three fundamental criteria that determine this diagnosis. For this reason, they have been investigated(1) and revised by several authors for decades(2,3). These studies have evolved toward the notion that the central point of language alterations within the autistic spectrum is related to language’s functional use, and have thus counted on contributions from pragmatic theories, which enable the articulation of language and aspects of interaction and cognition as an individual’s development unfolds; this scenario comprises exactly the triad of fundamental dominions that is used to diagnose autism spectrum disorders(4). In regard to aspects of conceptualization and diagnosis, the concept of autism spectrum(5) includes the axes that compose the diagnostic systems proposed by the American Psychiatric Association in the Diagnostic and Statistical Manual of Mental Disorders(6), and by the World Health Organization in the International Classification of Diseases(7). The diagnosis criteria in question always entail behavior observation and identification, since a biological marker has not yet been identified for autism(8). The concept of autism spectrum allows for the complex interrelation among several clinical situations and not only their juxtaposition(9). But a discussion still exists concerning exactly which disorders must be included in the autism spectrum, although there is little disagreement about the existence of a spectrum. The implications of diagnosis criteria based mainly on clinical observation have been extensively discussed(10), as well as differential diagnoses among the clinical scenarios that compose the autism spectrum(11). The notion that the most significant contribution that speech-language pathology and audiology can offer, both to research studies on the etiology of autism and to diagnostic processes, is the determination of a clearer language phenotype, has guided research concerning the best criteria to describe this population’s language, the best way to obtain them, alternatives to elicit better performances, and thorough data analysis. The aim of this study was to verify the applicability of a checklist to replace the complete protocol as a facilitating element in clinical and therapeutic follow-up processes. The participants were 50 children between 3 and 12 years of age who were assisted at a specialized service center on a weekly basis. The procedures do not entail the modification of any elements in the routine of semiannual reassessments of each patient under care; we only required the speech-language pathologists to fill out the checklist and to verify the occurrence frequency of each communicative function and their means of expression. With the results obtained, we sought to statistically compare the answers provided on the checklist to the performance of each child, revealed by means of the Functional Communication CoDAS 2013;25(6):605-9

Profile. The purpose was to verify a potential equivalency in the application of both instruments to investigate communication in children and teenagers within the autism spectrum. METHODS This study was approved by the institution’s Ethics Committee, under report number 228-11. The participants were 50 children aged between 3 and 12 years who were being systematically assisted on a weekly basis for at least six months (at least three months with the same speech-language pathologist), with diagnoses included in the autism spectrum. The inclusion criteria established for the study were: signature of the Informed Consent by one of the legal guardians of each participant, diagnosis included in the autism spectrum, and age under 12 years. The materials used to register the data were: digital camcorders, media (short DVDs), Functional Communication Profile protocols (Appendix 1) and Communicative Functions checklist (Appendix 2). Each individual was recorded between April and May of 2012, with the purpose of transcribing the footage data onto the Functional Communication Profile protocol. Before the data were transcribed, the therapists (speech-language pathologists) were asked to fill out the Communication Functionality checklist. After the instrument had been handed in to the researcher, the data obtained from the footage were transcribed. Following the transcription of footage data to the Functional Communication Profile, these were also given to the researcher, with the purpose of compiling the information in a table, so that we could compare the data using a statistical method. RESULTS The 50 Communicative Functionality checklists were filled out, and 50 footage pieces were transcribed onto Functional Communication protocols. All answers on the Communicative Functionality checklists were tabulated, as well as the data from the Functional Communication Profile protocols. Initially, it was necessary to equate the manner of classifying the results presented in both tests. Thus, we used the concept of quartiles for the answers on the Functional Communication Profile, and it was established that, in case a certain function was not observed, it would be classified as “never occurring”; if it happened between one and four times, it would be classified as “rarely occurring”; if it happened between five and 12 times, it would be classified as “occurring many times”; and if it happened 13 or more times, it would be classified as “frequently occurring”. With the results of both tests following the same pattern, it was necessary to find a numerical parameter for the answers. Based on the Likert scale, we attributed values from zero to three to the answers: zero for “never”, one for “rarely”, two for “many times”, and three for “always”. Lastly, we used Kruskal-Wallis’ test to find similarities or differences in the occurrence of functions in both tests.

The results indicated that, when the occurrence of each function was compared, different results were found in nine out of the 20 communicative functions (Table 1), namely: information request, protest, commentary, self-regulatory function, performative function, targeted, game, narrative, and protest expression, and in nine of the 50 individuals (Table 2).

does not characterize them; in other words, it is possible to know that they have different pragmatic profiles, but it is not possible to identify the frequency of occurrence of the functions. The results also suggest that the checklist can be utilized as an alternative form of assessment that complements the Functional Communication Profile. CONCLUSION
