Validation of the Russian and Kazakh Versions of the Beck Depression Inventory and Beck Anxiety Inventory Among Female Cancer Patients

BDI-II Score on day 14

时间窗: Day 14

Beck Depression Inventory (BDI-II) Scale is a 21-item self-reported questionnaire which measures the existence and severity of symptoms of depression. Each of the 21 items on BDI-II tool represents a depressive symptom. The symptoms are each scored on a 4-point Likert scale of 0 to 3 (0=symptom is absent; 3=symptom is severe). Scores for each symptom are added up to obtain the total scores for all 21 items. Total score ranges from 0-63; of which 0-8 is considered no depression, 0-13 is minimal depression, 14-19 is mild depression, 20-28 is moderate depression and 29-63 is severe depression.

BAI Score at Baseline

时间窗: Baseline

Beck Anxiety Inventory (BAI) is a 21-item self-reported questionnaire which measures the existenceand severity of symptoms of anxiety. Each of the 21 items on BAI tool represents an anxiety symptom. A total score of 0 - 7 is interpreted as a "Minimal" level of anxiety; 8 - 15 as "Mild"; 16 - 25 as "Moderate", and 26 - 63 as "Severe".

ICD-10 diagnosis at baseline

时间窗: Baseline

The ICD-10 sets criteria for diagnosis of major depressive disorder and generalized anxiety disorder, and will be used as a gold standard of diagnosis of depression and anxiety.

BAI Score Day 14

时间窗: Day 14

Beck Anxiety Inventory (BAI) is a 21-item self-reported questionnaire which measures the existenceand severity of symptoms of anxiety. Each of the 21 items on BAI tool represents an anxiety symptom. A total score of 0 - 7 is interpreted as a "Minimal" level of anxiety; 8 - 15 as "Mild"; 16 - 25 as "Moderate", and 26 - 63 as "Severe".

Internal consistency of the BAI

时间窗: Day 14

Internal consistency of the subscales will be evaluated with Cronbach's alpha. Values between 0.70 and 0.90 will be considered good and greater than 0.90 will be considered excellent.

Sensitivity and Specificity of the BAI at baseline

Test - retest reliability of the BDI-II questtionaire

时间窗: Day 14

Test - retest reliability of the BDI-II questtionaire on Day 14. Test-retest reliability coefficients vary between 0 and 1, where: 1 : perfect reliability, * 0.9: excellent reliability, * 0.8 \< 0.9: good reliability, * 0.7 \< 0.8: acceptable reliability, * 0.6 \< 0.7: questionable reliability, * 0.5 \< 0.6: poor reliability, \< 0.5: unacceptable reliability, 0: no reliability. On this scale, a correlation of .9(90%) would indicate a very high correlation (good reliability) and a value of 10% a very low one (poor reliability).
