What is the one week test-retest reliability for the BDI-II?

What is the one week test-retest reliability for the BDI-II?

Criterion validity of the BDI-II is positively correlated with the Hamilton Depression Rating Scale (r = 0.71) with a high 1 week test-retest reliability r = 0.93 (suggesting robustness against daily variations in mood) and an internal consistency of α = 91 [4].

What is the reliability and validity of the Beck Depression Inventory?

Results: The reliability results show that Cronbach alphas ranged from 0.75 to 0.92, whereas inter-item correlations ranged from 0.53 to 0.78. The validity analysis show that factor loadings for all items of Beck Depression Inventory ranged from 0.77 to 0.93.

Is the BDI reliable?

This study demonstrated that the BDI-II is a valid, reliable and culturally relevant instrument for measuring depressive symptoms in FCCCD and has a two-factor structure consisting of somatic-affective and cognitive factors.

How is BDI score calculated?

The BDI-II is scored by summing the ratings for the 21 items. Each item is rated on a 4-point scale ranging from 0 to 3. The maximum total score is 63. Special attention must be paid to the correct scoring of the Changes in Sleeping Pattern (Item 16) and Changes in Appetite (Item 18) items.

What does BDI 2 measure?

BDI-II – Beck Depression Inventory-Second Edition. The BDI-II is a widely used 21-item self-report inventory measuring the severity of depression in adolescents and adults.

How do you read BDI-II scores?

Cut-off score guidelines for the BDI-II are given with the recommendation that thresholds be adjusted based on the characteristics of the sample, and the purpose for use of the BDI-II. Total score of 0–13 is considered minimal range, 14–19 is mild, 20–28 is moderate, and 29–63 is severe.

What is the reliability and validity of the Beck anxiety Inventory?

The BAI has excellent overall internal consistency [17,18,19,20,21] and a high test-retest correlation (r = 0.67) [22]. The BAI also demonstrates good concurrent validity, with correlations between 0.78 and 0.81 with the SCL-90 Anxiety Subscale [23], the Hamilton Anxiety Scale [12] and Spielberger’s STAI [17].

What does validity and reliability mean?

Reliability and validity are concepts used to evaluate the quality of research. They indicate how well a method, technique or test measures something. Reliability is about the consistency of a measure, and validity is about the accuracy of a measure.

What is the reliability and validity of the Beck Anxiety Inventory?

What is the best depression Inventory?

The Beck Depression Inventory (BDI) is widely used to screen for depression and to measure behavioral manifestations and severity of depression. The BDI can be used for ages 13 to 80. The inventory contains 21 self-report items which individuals complete using multiple choice response formats.

What is a BDI test?

The Beck Depression Inventory (BDI) is a 21-item, self-rated scale that evaluates key symptoms of depression including mood, pessimism, sense of failure, self-dissatisfaction, guilt, punishment, self-dislike, self-accusation, suicidal ideas, crying, irritability, social withdrawal, indecisiveness, body image change.

Is BDI ratio or interval?

Most measurements of psychological attributes are not ratio scale measurements but are assumed to be interval scale attributes. For instance, the Beck Depression Inventory (BDI) is scored on a 0 – 63 scale with higher scores representing higher levels of depression.

How reliable is the BDI-II?

The BDI-II positively correlated with the Hamilton Depression Rating Scale, r = 0.71, had a one-week test–retest reliability of r = 0.93 and an internal consistency α=.91.

Are the BDI-II and the TGDs test-retest reliabilities useful in clinical settings?

The test-retest reliabilities of the BDI-II and the TGDS are high. The MDCs of both measures are acceptable to nearly excellent in people with PD. These findings imply that the BDI-II and the TGDS are suitable for use in a research context and in clinical settings to detect real change in a single s …

What is test-retest reliability?

Test-retest reliability refers to the extent of agreement between measurements of a measure in successive sessions [ 8 ]. In addition, random measurement error exists in all assessments. If the measurement error of a measure is not determined, the interpretability of the test scores is limited [ 9, 10 ].

Is the BDI-II a useful measure for diagnosing depression?

Criterion-based validity have also shown acceptable sensitivity and specificity of the BDI-II for detecting depression, supporting its clinical utility as an aid measure for diagnostic purposes [2,14,15].
