Abstract

The research involved a systematic review of randomized controlled trial journals about Lidcombe Program to provide statistical data from multiple studies to improve estimates of the effect size and to examine the magnitude of the effectiveness of the program in pre and post % syllable stuttered. It aimed to determine if there was a significant difference in the pre and post treatment percentages of syllable stuttered (%SS) score of preschool children who underwent the Lidcombe Program. Electronic search was done on online databases such as ASHAWire, Google Scholar and National Center for Biotechnology Information (NCBI). After three (3) levels of screening, five (5) journals were eligible for the review and analysis. The population from the five (5) journals were not homogenous, hence a non-parametric test was used. Results showed that there was a significant difference of the pre and post treatment tests. The first hypothesis, which stated that the difference between pre and post scores is not equal to zero, attained the p-value of 7.75e 12<0. The second hypothesis, which stated that the difference between pre and post scores is greater than zero, attained the p-value of 3.87e -12<0. Both indicated that there was a positive difference between the pre and post test, suggesting that stuttering decreased after the participants underwent the Lidcombe Program. The effect size attained a value of 0.88, indicating that the Lidcombe Program had a significant effect in the difference between the pre and post treatment.
