Abstract
|
|
|
Objectives: This study looked at the symptoms of alexithymia in schizophrenia and their association with clinical variables and schizophrenic symptomatology.
Methods: Consecutive fifty eight inpatients with DSM-IV diagnoses of schizophrenia completed 26item version of Toronto Alexithymia Scale (TAS), Symptom Checklist-90-Revised(SCL-90-R), and Positive and Negative Syndrome Scale(PANSS).
Results: Authors did not find any correlation between scores of PANSS and TAS. However, all the subscale scores of SCL-90-R were significantly correlated with total score of TAS. Also, ’difficulty identifying and deistinguishing between feelings and bodily sensations’ and ’difficulty describing feelings’ significantly correlated with SCL-90-R subscale scores. ’Reduced daydreaming’ had mixed findings and ’externally oriented thinking’ did not correlate. Multiple regression model included Global Severity Index of SCL-90-R accounting 28.2% of variance for TAS scores.
Conclusion: These findings together with discrepancy in results between objective and subjective tests suggest that alexithymia in schizophrenia may have two constructs, ’difficulty to describe and communicate feelings(state)’ and ’externally oriented thinking(trait)’ Authors suggest further study needs to confirm construct validity of TAS in this population.
