What this trial studies
This observational study aims to validate the Lithuanian versions of the Brief Negative Symptoms Scale, Calgary Depression Scale for Schizophrenia, and Schizophrenia Cognition Rating Scale. Participants aged 18 to 65 with specific schizophrenia diagnoses will be evaluated using these scales alongside established measures like the Positive and Negative Symptoms Scale and the Montreal Cognitive Assessment. The study focuses on assessing the convergent and discriminant validity of these scales to ensure they accurately reflect the symptoms of schizophrenia in the Lithuanian population.
Who should consider this trial
Good fit: Ideal candidates for this study are adults aged 18 to 65 with a diagnosis of schizophrenia or related disorders.
Not a fit: Patients with comorbid diagnoses of mental retardation or substance use disorders may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could enhance the accuracy of mental health assessments for schizophrenia in Lithuania, leading to better patient care.
How similar studies have performed: While similar validation studies have been conducted, this specific validation for the Lithuanian population is novel.
