- Abstract
Objective: Thought and Language Index (TLI) is a semistructured clinical interview scale for assessing thought and language disorders in patients with schizophrenia. This index has been translated and adapted into Turkish language in order to study its validity and reliability. Method: 82 patients with schizophrenia and 49 healthy volunteers were included in the study. Socio-demographic data form, TLI, Positive and Negative Syndrome Scale (PANSS) and Calgary Depression Scale (CDS) were administered to patients with schizophrenia. Sociodemografic data form and Structured Clinical Interview for DSM-IV /Clinical Version (SCID-I/CV) were applied to the healthy controls. For the reliability evaluation of the index interrater reliability and test-retest reliability and for the validity of the index, factor structure and differentiation capacity between patients and healthy volunteers were investigated. Results: Poverty of thought and disorganization of thought were found as two factors in TLI's factor analysis. We determined high interrater reliability (r=0.97 for poverty of thought, r= 0.72 for disorganization of thought) for TLI. Test-retest reliability of poverty of thought was higher than that of disorganization of thought (r=0.78 for poverty of thought, r=0.44 for disorganization of thought) and TLI has high differentiation capacity between patients and healthy volunteers (p<0.001). Distractibility item of the index was not found valid and reliable. The test retest reliability of looseness was poor. The correlation between items of CDS and TLI was not significant. Conclusion: The validity and reliability of distractibility and looseness items of TLI must be tested also in acute schizophrenic patients.
