Catalogue of Paediatric Speech Language Pathology Reviews
Systematic Review Methods

Identification and Examination of Relevant Articles

Step 1 – Search Strategies
Database searching was not an adequate procedure for constructing the Catalogue because reviews of research were not reliably indexed. Therefore, we searched by hand the tables of contents of each issue of 10 peer-reviewed journals published between 2000-2006, as well as the entire Cochrane Library. The 10 journals were selected based on the impact factors (Web of Science), and in consultation with speech language pathologists. Book Reviews, Letters to the Editor, résumés, position statements, announcements, and so forth were not included.

Step 2 – Inclusion/Exclusion Criteria
Inclusion and exclusion criteria were established by a team of researchers and speech language pathologists trained in systematic review methods. Inclusion and exclusion criteria were applied to the titles and abstracts of identified articles (N=4917).

Outcomes

Language, speech, social development and skills, quality of life, learning and school achievements 

Economic only

Two researchers assessed the reliability of the application of inclusion and exclusion criteria to the titles and abstracts of approximately 30% (578) of the 2132 articles found in the 10 journals. They disagreed on the inclusion of 8 articles; reliability high, kappa = .83. The 8 disagreements were resolved by consensus during the evaluation of the full text of the articles.

Step 3 – Results

Resultant Number of Citations

Search of 10 journals and Cochrane Library

Application of inclusion/exclusion criteria to full text of each article

65

*primary reasons for exclusion: journal article was not a review of research; Cochrane review
  was unrelated to speech language pathology

Step 4 - Data Extraction
Information from each of the 65 reviews was extracted and recorded in a spreadsheet. Categories of information included factors relating to review methods, purpose of the review, client populations, assessments and intervention methods, results, conclusions, and useful features of the review.
