groups. The reaction time measures (lip and larynx) clustered independently of the speech fluency measures, and results indicated duration of laryngeal adjustment times differentiated both groups. The authors suggest that fluency failures and laryngeal adjustment time measures should be useful in differentiating stutterers from nonstutterers. STUTTERING Conture, E. G. and Wolk, L., Syracuse University, Syracuse, New York. The Efficacy of Speech-Language Pathology Intervention. Seminars in Speech and Language, (1990) 1 I, 200209. The authors discuss efficacy of stuttering therapy, noting that little agreement exists on what constitutes effectiveness. The 14 criteria suggested by Bloodstein in 1987 are used to illustrate the complexity of defining the idea of effectiveness. The present focus on measuring rate, dysfluency types, and the frequency-duration-severity of stuttering. However, the authors point out problems of definition, description, and interjudge/intrajudge variability. They report that differences among those counting stuttering are often greater than the extent of change, which is used to justify the success rate reported in many therapy studies. A second accountability area, more difficult to measure includes various attitudes of the client, as well as specific anxieties and fears relative to speech. A third area, the most unclear for assessment, discusses four aspects. How natural end-result speech is, and the degree to which changes are produced automatically (as opposed to conscious control) are considered. Shifting Locus of Control from external (control by environment) to internal (self-control) is a third aspect. Related to lows of control is the degree of Learned Helplessness, or how much the client feels under the control of an entity called “stuttering.” Finally, discussion urges further research to confront the three measurement areas and to develop adequate assessment procedures for them. USE OF THE MONTEREY PROGRAMMED STUTTERING THERAPY IN GREAT BRITAIN Rustin, L., Bloomsbury, Hampstead, and Islington Health Authorities, London; Ryan, B. P., California State University; Ryan, B. V., County Schools Service, Los Angeles. British Journal of Disorders of Communication, (1987) 22, 151-162. The authors report the use of the Monterey Fluency Program in Great Britain. Over a 5-year period, 221 clinicians were trained in four-day workshops to use MFP methods, and asked to send back data on at least
