Objectives: This study aimed to adapt the short form of the 12-item Highly Sensitive Child (HSC) scale into Turkish and examine its factor
structure, validity, and reliability in school-age children and adolescents.
Materials and Methods: 139 children and adolescents aged 8-18 years were reached. A total of 126 participants completed the HSC scale
completely. In parallel with the original version, one-factor, three-factor, and bifactor models were tested in the Turkish sample. Negative
Emotionality, Effortful Control, Perceptual Sensitivity, Behavioral Inhibition, Behavioral Activation System (BIS/BAS), Negative Affect, and
Positive Affect scales were used to test the validity.
Results: The confirmatory factor analysis showed that the one-factor structure was incompatible with the data, while the bifactor model was
rejected. The three-factor model was accepted as the most compatible model with the data. The reliability values of the scale were found to be
at acceptable values except for the Aesthetic Sensitivity subscale. Cronbach's alpha values were.68 for the 5-item Ease of Excitation subscale,.43
for the 4-item AES subscale,.63 for the 3-item Low Sensory Threshold subscale, and.64 for the 12-item HYC scale. The fact that the correlations
of HYC and its subscales with similar temperament traits were in the expected directions points to the convergent validity of the scale. A
significant percentage of the variances in HYC and its subscales were not explained by the similar scales examined, showing the discriminant
validity of the scale.
Conclusion: As a result, it was found that the Turkish adaptation of the HYC scale was psychometrically adequate.
