Impact Factor Information

Impact factors, calculated and reported by Thomson Scientific's ISI Web of Knowledge, represent one way of measuring the impact of a scientific journal on the scientific discipline it covers. The impact factor represents a ratio calculated by dividing the number of current year citations to the articles published by a journal during the preceding two-year period by the number of source or "citable" articles published in that journal in the same two year period. Higher scores indicate more citations and, presumably, higher impact.

American Journal of Speech-Language Pathology (AJSLP)

The 2012 impact factor is 2.448, and the 5-year impact factor is 2.897. AJSLP ranks 3rd of 160 journals in the Linguistics category and 5th of 66 journals in the Rehabilitation category. AJSLP's articles have a "cited half life" of over 7.8 years—showing their enduring impact and use.

Journal of Speech, Language, and Hearing Research (JSLHR)

The 2012 impact factor is 1.971, and the 5-year impact factor is 2.745. JSLHR ranks 7th of 160 journals in the Linguistics category and 9th of 66 journals in the Rehabilitation category.

With a "cited half life" of over 8 years, JSLHR is an essential source for current and future researchers in a wide variety of disciplines. JSLHR is also ranked the most cost-effective journal in Applied Linguistics and the 6th most cost-effective in Rehabilitation.

Language, Speech, and Hearing Services in Schools (LSHSS)

The 2012 impact factor is 1.256, and the 5-year impact factor is 1.520. LSHSS ranks 24th of 160 journals in the Linguistics category and 25th of 66 journals in the Rehabilitation category.

LSHSS has a "cited half life" of nearly 8.5 years, and it ranked the 9th most cost-effective journal in Applied Linguistics and ranked 13th most cost-effective in Rehabilitation.
