Over the past 5 years, there has been quite a dramatic decline in the number of data-based investigations or reports on or concerning stuttering therapy for adults or adolescents. After reviewing all English language journal publications that fit this category, this writer found that in 1973-1977 there were 57 reports, in 1978-1982 there were 50 reports, but in 1983-1987 (and including half of 1988) there were only 25 reports.
