Collaboration trend on Speech, Language and Hearing Sciences: A Scientometric Study Based on Select Journals

Abstract

Collaboration trend among researchers can take many forms. One of the most tangible forms of this collaboration is co-authorship. Over the decades the multiple-author publication, frequently referred to as a co-authored publication, has been used as a basic counting unit to measure collaborative activity.  In order to identify the collaborative trend in speech, language and hearing science three leading journals such as Journal of Speech, Language and Hearing Research, published by American Speech and Hearing Association (ASHA), Asia Pacific Journal of Speech, Language and Hearing and Journal of the All India Institute of Speech and Hearing (JAIISH). A total of 905 articles were published in these three journals during the period of 2009-2013 has been considered for the study. Scienctometric tools such as Authorship pattern Collaborative Author Index, Degree of Collaboration. Collaboration Index, Collaborative Coefficient and Modified Collaborative Coefficient, Local collaborative index, Domestic collaborative index, International collaborative Index were used. The study shows that there exists collaborative research in speech, language and hearing sciences journals irrespective of the origin of the journal. The local collaboration of authors was more rather than domestic and international collaboration among the authors.  The study also shows that there is no significant difference in collaboration in the domain of speech or language or hearing and Local collaboration persist in the domain of speech or language or hearing.
