Abstract
Studies showing stronger scientific evidence related to speech, language and hearing pathology (SLP) have an impact on the prevention and rehabilitation of human communication and gained ground in SLP research agenda. In this paper we discuss some aspects and directions that should be considered for in-depth knowledge about speech, language and hearing needs in different population groups (age group, gender and other variables according to specific related disorders) for improved comprehensive care, successful efforts and effective use of financial and human resources. It is also discussed the decision making process for requesting complementary evaluations and tests, from routine to highly complex ones, that should be based on each test and/or procedure and their contribution to the diagnosis and therapeutic planning. In fact, it is crucial to have reliable parameters for planning, preventing and treating human communication and its related disorders. Epidemiology, biostatistics and social sciences can contribute with more specific information in human communication sciences and guide more specific studies on the international science and technology agenda, improving communication sciences involvement in the international health-related scientific scenario.
Highlights
Given the premise that human communication is an important instrument to share experiences involving human beings, there is a need to acquire further knowledge about speech, language and hearing biological processes and variables involved in communication disorders
In this paper we focus on some topics to discuss the rational use of technology to evaluate, treat or prevent communication disorders and its association to population surveys
Articles as the present one, and other education resources, cannot by themselves improve, up to an acceptable level, the quality of statistics in biomedical journals, and factors which are core to biomedical research process should be considered (Alexander 2007, Goulart and Chiari 2007b)
Summary
Given the premise that human communication is an important instrument to share experiences involving human beings, there is a need to acquire further knowledge about speech, language and hearing biological processes and variables involved in communication disorders. In-depth knowledge about speech, language and hearing needs in different population groups (age group, gender and other variables according to specific related disorders) is vital for more effective efforts and use of financial and human resources, as well as to support the development and improvement of actions for human communication health maintenance and promotion in collective health. It comes, whenever is possible, to develop collective health. One should bear in mind all these considerations while planning and conducting studies that could provide more detailed data about the objects of study
