Coefficient alpha estimates reliability for the BDI-II with the outpatient sample was. To test the psychometric properties of the BDI-II a study was conducted with a clinical sample of 500 outpatients, and a convenience sample of 120 Canadian college students. Qualification Level: C therefore, professional school counselors cannot administer this assessment but should understand it’s functions and results. Pessimism, past failures, guilty feelings, self-dislike, self-criticalness, suicidal thoughts or wishes, crying, loss of pleasure, irritability, changes in appetite, changes in sleep patterns, and indecisiveness (Mental Measurements Yearbook, 2001).The remaining original items still included on the BDI-II are: ![]() Some BDI items have been dropped for the BDI-II such as items including body image change, work difficulty, weight loss, and somatic complaints, and have been r eplaced with items pertaining to agitation, worthlessness, loss of energy, and concentration difficulty. ![]() The BDI-II was revised from the original BDI (1961), and the changes have shown improvements in psychometrics, and the revised BDI-II adheres to the contemporary diagnostic criteria for depression in the DSM-IV (Mental Measurements Yearbook, 2001). Pending the results of further studies, the attributes of the PHQ-9, of being shorter and based on the diagnostic criteria for depression, may indicate an advantage over the BDI-II.īDI-II PHQ-9 depression psychometric properties treatment.The Beck Depression Inventory-II (BDI-II) (1996) is a universally used instrument in assessing and screening depression in individuals ages 13 and over in clinical and non-clinical settings. Differences were found in how they categorised severity. The BDI-II and PHQ-9 demonstrated adequate reliability, convergent/discriminant validity, and similar responsiveness to change. The consistency of agreement on indices of clinical significance was fair to moderate, but the BDI-II categorised a greater proportion of participants with severe depression than the PHQ-9. Responsiveness to change of PHQ-9 and BDI-II was similar at both posttreatment and follow-up. Both scales converged more with each other than with the Sheehan Disability Scale at pre- but not at posttreatment. Factor analysis failed to confirm the one-factor model previously reported for the PHQ-9, but two factors evidenced good fit for the BDI-II. Both scales demonstrated adequate internal consistency at pre- and posttreatment (PHQ-9 α =. Tests of internal consistency (Cronbach's α), factor analyses, correlational analyses, estimates of clinically significant change, and effect sizes (Cohen's d) were calculated after treatment and follow-up. The PHQ-9 and BDI-II scores from 172 depressed participants in two randomized controlled trials of treatment for depression were assessed and combined. ![]() The authors assessed psychometric properties of both measures during treatment for depression. The Patient Health Questionnaire-9 Item (PHQ-9) and Beck Depression Inventory-II (BDI-II) are frequently used measures of depression severity, but little is known about their relative psychometric properties. ![]()
