Ha, S. (2015). Effectiveness of a parent-implemented intervention program for young children with cleft palate. International Journal of Pediatric Otorhinolaryngology, 79, 707-715. doi: 10.1016/j.ijporl.2015.02.023.
2. Over the past 20 years, studies have shown that children with cleft palate are likely to have speech-language impairments. Effective early intervention can help reduce the need for more intensive clinician-implemented intervention (Ha, 2015). Research has shown that parental involvement is …show more content…
an important part of effective early intervention programs for children less than three years of age. Ha cites Scherer and colleagues’ study in which they trained mothers to deliver speech intervention to their children with a cleft palate. In this study, the experimental group was compared to a group of typically developing peers at the same language development level. They did not compare the experimental group to a control group. Results from the study showed an increase in speech accuracy and increase in sound inventories.

The purpose of this study was to analyze the effectiveness of parent-implemented intervention for young children with cleft palate. Effectiveness was assessed based on changes in speech language performance by comparing children with mothers that received training in communication strategies compared to those who had mothers who did not receive training (Ha, 2015).
4. Participants for the study included seventeen children with non-syndromic cleft palate (CP) and their mothers. Data collected on the children originated from a medical history form filled out by the parents. According to parents’ reports, each child had a surgery for primary palate repair. The intervention group consisted of 17 participants, 10 girls and 7 boys. The control group consisted of 9 participants, 5 girls and 4 boys.
5. Data were collected during two assessments at 3-month interval. Two 20-minute video and audiotaped language samples and standardized tests were used to collect data. One 20-minute language sample involved the evaluator and child interaction, and the other sample involved the mother and child interaction. The standardized tests used in the study were a Sequenced Language Scale for Infants (SELSI) and Korean MacArthur-Bates Communicative Development Inventories …show more content…
(KM-BCDI).
6. Many graduate and undergraduate students studying speech pathology were trained to transcribe and analyze data for this study. All analyzers and transcribers were blinded to the purpose of the study. First, undergraduate students conducted orthographic transcriptions of each language sample (Ha, 2015). Then two graduate students and the researcher examined the transcriptions for accuracy. Two graduate students then conducted phonetic transcriptions of the samples. If any disagreement occurred while transcribing, the researcher joined with the two graduate students to listen to and analyze samples together to determine the final transcription for data analysis (Ha, 2015).

Results from the study suggest that parent-implemented intervention for children with CP has a positive impact on their speech and language performance. Results indicate that children in the intervention group showed significant increases in number of expressive vocabulary on the KM-BCDI and expressive language age on the SELSI (Ha, 2015). Children who did not receive parent-implemented intervention “…showed a significant increase in only expressive language age…” on the SELSI (Ha, 2015). After intervention, the intervention group showed a significantly greater number of expressive vocabulary, true consonants, total words, and measures of vocabulary size compared to the control
group.
8. For future research, more opportunities for training should be made available. Only one training session was conducted for each parent due to distances and limited resources. Although mothers could communicate with the researcher via phone and email, more training sessions would be beneficial. In addition, fewer children were used for the control group compared to the intervention group. Further studies should include a larger sample size and the same amount of participants in each group.
9. Ethical issues were addressed as appropriately as they could be. The formal Institutional Review Board at the university was not available when the study was being done, so principles in the Declaration of Helsinki were followed (Ha, 2015). Children’s parents signed consent forms before the study started.
10. If I could ask the researcher questions, one of them would be: how did you manage to conduct a study by following the principles of the Declaration of Helsinki (because there was no IRB available)? How did you manage to ensure the study was conducted efficiently and ethically? Can this parent-implemented intervention program be used for children with other disabilities, not relating to CP?
