Turkish IPDT: Inventory of Piaget's Developmental Tasks (IPDT-TR) and cognitive development characteristics of a group of university students

This study was carried out to evaluate the psychometric properties (reliability and validity) of Inventory of Piaget's Developmental Tasks and to examine the cognitive development characteristics of a group of university students. The introduction of IPDT-TR to our country, integrating therapeutic relationship between the client and therapist, treatment methods, and what is known about the other aspects of the therapy process with developmental theory is considered important to provide a tool for therapists to accurately assess clients and select interventions most likely to ensure successful therapy outcomes. The study group was 463 (350 female, 113 male) university students between the ages of 18-24. In this study, Sociodemographic Information Form, Inventory of Piaget's Developmental Tasks (IPDT-TR) and Kent Egy Intelligence Test were applied, and the data obtained from the participants were analyzed with the SPSS program. As a result of the Cronbach Alpha reliability analysis performed within the scope of the measurement reliability of the Turkish form of Inventory of Piaget's Developmental Tasks, the internal consistency coefficient of the Turkish form was determined to be 0.88, which reflects the acceptable reliability level. As a result of the test-retest reliability analysis, the correlation coefficients between the subtest scores except IPDT-TR movement and seriation subtests were found to be between 0.351 and 0.741 and statistically significant. As a result of the analysis performed within the scope of criterion validity, the correlation coefficients between the subtest scores except IPDT-TR quantity subtest and the Kent Egy Intelligence Test scores were found to be between 0.111 and 0.276 and statistically significant. Findings obtained from the study were discussed together with the literature.
