Efficacy of the Adapted Cycles Intervention Program (PROCICLOS-A) and the influence of severity on the performance of children with Speech Sound Disorders.

Purpose: To verify the efficacy of PROCICLOS-A in children with SSD, according to the weekly frequency of sessions, and the severity's influence on the sessions' performance.

Methods: Eight children with SSD participated, both sexes, ages between 5:03 and 7:07 years, divided into two groups: C1, once a week; C2, twice a week. The efficacy of PROCICLOS-A was verified in C1 and C2 by analyzing variables from the phonology tests of the ABFW assessment across three evaluation moments. The performance in the sessions was obtained through scoring the activities.

Results: All measures significantly differed, indicating improved performance in the evaluations after the intervention. Regarding the influence of the frequency of the sessions, there was no significant difference between C1 and C2 in the three evaluation moments. Blocks of sessions analyzed the performance in the sessions: A (sessions 1, 4, 7, 10), B (sessions 2, 5, 8, 11), C (sessions 3, 6, 9, 12). The analysis revealed lower performance during the sessions of Block A, while Blocks B and C demonstrated better performance.

Conclusion: The study provided evidence for the efficacy of PROCICLOS-A, regardless of the dosage and frequency of sessions. It suggests that maintaining the cumulative intensity of the intervention is vital, indicating that the total number of intervention hours may have a greater impact than the number of sessions held per week. There was an improvement in each child's performance throughout the program, regardless of the target sound and severity at the beginning of the intervention.
