Validation of the Persian Version of the Palin Parent Rating Scales.

Introduction: The Palin Parent Rating Scale (Palin PRS) is a structured questionnaire filled out by parents of children who stutter. It is designed to assess the effects of stuttering on both the children and their parents. The goal of this study was to translate the Palin PRS into Persian and to evaluate its validity and reliability for application in preschool children who stutter.

Methods: This research was conducted from August 2021 to December 2022, involving 139 parents of children who stutter. The parents completed the Palin PRS and provided their demographic data. Descriptive statistics were used to examine the floor and ceiling effects on all subscales of the Palin PRS. The internal consistency of the scale was assessed using Cronbach's alpha method, while the intraclass correlation coefficient (ICC) was calculated to determine its test-retest reliability. An exploratory factor analysis was also performed to clarify the factor structure of the scale.

Results: The exploratory factor analysis results were highly consistent with the factor structure found in the original version. No floor or ceiling effects were observed for the factors of the Palin PRS. The three factors of the Persian version of the Palin PRS (P-Palin PRS) showed good internal consistency (Cronbach's alpha >0.8) and excellent test-retest reliability (ICC >0.9). Additionally, normative scores were derived by converting raw scores into Stanine scores.

Conclusion: The P-Palin PRS showed strong reliability, thereby establishing it as a suitable instrument for evaluating how parents perceive the effects of stuttering on their children and themselves. Further research may explore its application in diverse clinical settings and populations.
