Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To estimate the prevalence of patients diagnosed with Generalized Anxiety Disorder based on DSM-5 diagnostic criteria, which is confirmed by SCID. | — |
Secondary
| Measure | Time frame |
|---|---|
| -To evaluate patient health, QoL and functional status related scores using EuroQoL 5-dimension 5 Level (EQ-5D-5L), Quick Inventory of Depressive Symptomatology Self-Report (QIDS-SR), Sheehan Disability Scale (SDISS), GAD-7, Adverse Childhood Experiences(ACE) calculator and K6. Also, Generalized Anxiety Disorder patient severity of illness will be assessed using the Clinical Global Impression Severity Scale (CGI-S). -To estimate the prevalence of patients with primary diagnosis of Generalized Anxiety Disorder based on the DSM-5 diagnostic criteria, which is confirmed by SCID. -To estimate the prevalence of patients diagnosed with Generalized Anxiety Disorder by ICD-10 diagnostic category diagnosed prior to this study. -The percentage of psychiatric disorders diagnosed other than Generalized Anxiety Disorder by SCID. -The percentage of psychiatric disorders comorbid with Generalized Anxiety Disorder by SCID. -The percentage of diagnostic agreement with the GAD-7 total score. -The percentage of diagnostic agreement with the K6 total score. -To determine the factors (variables: age, gender, family history, treatment history, medical history, disease name according to ICD-10 diagnosed prior to study participation, etc.) associated with Generalized Anxiety Disorder. -The validity of the diagnosis of Generalized Anxiety Disorder by GAD-7 and K6 in comparison to the diagnosis by SCID. | — |
