Objective: In this study we aimed to examine the Turkish validity and
reliability of the UPPS-P Impulsive Behavior Scale for Children (UPPSP-
C) and to investigate whether there is a relationship between the UPPSP-
C subscales and Attention Deficit Hyperactivity Disorder (ADHD).
Method: A total of 575 children aged 10-14 years were included in
the study. The clinical sample of the study consisted of 50 children
with ADHD who had not received treatment for at least 1 month and
525 children living in Sinop as the community sample. In order to
investigate the test-retest reliability, UPPS-P-C was re-administered to
50 different children selected from the community sample.
Results: Factor analysis displayed a five-factor model for the test. ‘Lack
of premeditation’ and ‘Lack of perseverance’ had the highest ability to
distinguish children with ADHD. The Cronbach α coefficient was
found to be 0.894 for the UPPS-P-C. For the test-retest reliability of
the UPPS-P-C, the correlation between the total and subscales of the
two tests was examined using ICC, the Spearman’s Rank Correlation
Coefficient and Bland Altman graphs, and the reliability was good.
Conclusion: Our findings show that the Turkish version of the UPPSP-
C has good validity and reliability and is successful in screening for
features related to impulsivity. It has been shown that the UPPS-P-C
can be used for symptom profiling and severity assessment.
