One preschool male who was highly unintelligible was enrolled in two cycles of direct intervention utilizing the phonological cycling approach (Hodson & Paden, 1991). Prior to treatment in cycles 1 and 2, the Assessment of Phonological Processes-Revised (APP-R) (Hodson, 1986) was administered to the subject to assess phonological deficiencies and to determine the target phonological patterns. A continuous speech sample was collected prior to cycle 1 to rate speech intelligibility. Based on the results obtained from the APP-R, target patterns, target words, and an individualized treatment plan were developed for each cycle. For the first cycle of intervention, the subject participated in 60 minutes of direct intervention twice a week for 5 weeks, and in cycle 2, the subject participated in 60 minutes of direct intervention twice a week for 4 1/2 weeks. Each treatment session followed the procedures as outlined by Hodson and Paden (1991). Baseline measures were administered at the beginning of each session and probes were administered once a week. At the conclusion of both cycles, the APP-R was re-administered and a 100-word speech sample was collected. The results of the pre- and post-tests for cycles 1 and 2, baseline measures, weekly probes, and the intelligibility ratings were analyzed to determine the effectiveness of the phonological cycling approach in achieving a decrease in severity level of unintelligibility after two cycles. Results from the APP-R indicate that the subject's severity interval rating decreased from profound to severe. A comparison of pre- and post-intelligibility ratings showed an increase in intelligibility of 1.5 points on a 7-point rating scale. Based on the probes, generalization to nontreatment words in targeted and nontargeted patterns was noted in both cycles for some patterns. Overall, the phonological cycling approach was effective in achieving a decrease in severity level of intelligibility after two cycles of intervention for this subject.
