12. Uluslararası Psikofarmakoloji Kongresi & 8. Ulusalararası Çocuk ve Ergen Psikofarmakolojisi Sempozyumu, Antalya, Turkey, 17 - 20 November 2021, pp.124-125
BACKGROUND AND AIM:Formal thought disorder (FTD) is defined as disruptions in thought, language and communications. The aim of this study is to evaluate psychometric properties of scales measuring FTD within child and adolescent inpatients.
METHODS:56 inpatients (16.6±1.1, 50.0% female) with a psychotic (n = 28), depressive (n = 17), and manic (n = 11) episode were interviewed
using the 30-item Thought and Language Disorder (TALD) scale, together with the Scale for the Assessment of Negative Symptoms (SANS), the
Scale for the Assessment of Positive Symptoms (SAPS), the Young Mania Rating Scale (YMRS) and the Children's Depression Rating Scale
RESULTS:The TALD total score was correlated with the SAPS-FTD subscale score and YMRS total score (r=0.632 p<0.001; r= 0.585 p<0.001,
respectively). Also, objective positive symptom subscale of TALD scores were correlated with the SAPS-FTD subscale score and the YMRS total
score (r=0.773 p<0.001; r= 0.627 p<0.001, respectively). In addition, YMRS-item 6 (speech), YMRS-item 7 (thought and language) and the sum
of item 6+item 7 also showed a high correlation with the SAPS FTD total score (r=0.73 to 0.82, all p values < 0.001). The sum of item 6 + item 7
was negatively correlated with the SANS-FTD total score (r = - 0.28, p=0.039).
CONCLUSIONS:Results indicated a high convergence between TALD and SAPS for the assessment of FTD in youth. Specific items of YMRS also
could be useful to detect FTD in children and adolescents.
