PURPOSE: The Palin Parent Rating Scales (Palin PRS) is a standardized tool designed to measure (1) the impact of stuttering on a child, (2) the severity of stuttering and its impact on parents, and (3) parents' knowledge about stuttering and their confidence in managing it. This study examines the validity and reliability of the Turkish adaptation of the scale.
METHODS: Participants included 193 parents of 118 children who stutter aged 3;0-14;1 years. Analyses included confirmatory factor analysis (CFA), item response theory using the graded response model, internal consistency analyses (Cronbach's alpha, McDonald's omega, and Guttman's lambda), composite reliability, and test-retest reliability.
RESULTS: The CFA supported the scale's original structure and validated the model after reordering three item pairs within the factors, with the final model showing acceptable fit indices (χ2 = 387.78, χ2/df = 2.67, p < .01; IFI =.91; CFI =.90, and RMSEA =.09). The results supported measurement invariance between mothers and fathers, with values from .71 to 6.44. Composite reliability values ranging from .82 to.92 provided evidence of convergent validity. Reliability coefficients were satisfactory (≥.83), and test-retest results confirmed temporal stability (r = .64-.72).
CONCLUSION: The results of the psychometric analyses, including validity and reliability assessments, confirmed the three-factor, 19-item structure of the original version in its Turkish adaptation (Palin PRS-TR). Therefore, the Palin PRS-TR is a valid and reliable instrument for use in clinical and scientific settings.
