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). The questionnaire has three subscales, to measure a childs speech behaviors, parents worries about their childs speech behaviors, and the parents attitude towards their childs speech behaviors. Methods: The original S-PDQ was translated and adopted into Turkish. The Turkish version (S-PDQ-T) was administered parents of 65 children who stutter (CWS) and of 196 children who do not stutter (CWNS). The questionnaire is a 62-item, 4-point Likert type scale. The reliability of the scale was made with internal consistency (Cronbach's alpha) coefficient and test-retest correlation. The S-PDQ-T was also correlated with three other scales for the content validity; Ways of Coping Questionnaire, Parental Attitude Research Instrument and State-Trait Anxiety Inventory. Results: Cronbachs alpha coefficient was 93.9%, 95% and 79.1% for subscale I, II, III respectively. The correlation of the test re-tests at 10 weeks was 0.97, 0.78, and 0.86 for subscale I, II, and III. Conclusion: The results concerning the construct, discriminative, and criterion validity of the S-PDQ-T as well as its reliability coefficients of total, the subscale, and test-retest reliabilities indicate that its psychometric properties were at satisfactory levels. Parents are viewed as powerful components of the rehabilitation team at all stages of intervention. Knowing their beliefs, the way they look at their childs speech behavior will enable clinicians to help them to cope with and prepare a stable, easy to speak environment starting at home. Clinicians utilize the S-PDQ-T for management purposes. [Anadolu Psikiyatri Derg 2016; 17(0.100): 83-92]
