Objective: The purpose of the study was to determine the validity and reliability of the Turkish version of the Stuttering-Parental Diagnostic Questionnaire (S-PDQ-T). The questionnaire has three subscales, the child's speech behaviors from the perspective of the parents; parents' worries about their child's speech, and the parents' attitudes toward their child's speech. Methods: The original S-PDQ was translated and adapted into Turkish. The S-PDQ-T was administered to parents of 65 children who stutter (CWS) and of 196 children who do not stutter (CWNS). The questionnaire is a 4-point Likert type scale, and has 61-items. The reliability of the scale was made using internal consistency coefficient and test-retest correlation. The S-PDQ-T was also correlated with the Ways of Coping Questionnaire (WAYS), Parental Attitude Research Instrument (PARI) and State-Trait Anxiety Inventory (STAI) for the content validity. Results: The internal consistency coefficient was 93.9%, 95% and 79.1% for three subscales of the S-PDQ-T. The test-retests reliability at 10 weeks was high (0.97, 0.78, and 0.86 for subscale I, II, and III). Also, The S-PDQ was statistically and positively correlated with WAYS, PARI, and the STAI confirming concurrent validity. Conclusion: The results indicate that psychometric properties of the S-PDQ-T were at satisfactory levels. Knowing the parents' attitudes toward their child's speech behavior will enable clinicians to help them to cope with and prepare a stable, easy to speak environment. The S-PDQ-T can be used to obtain reliable information on parental attitudes for cooperation in stuttering management.
