Validation of a Tibetan translation of the Hopkins Symptom Checklist 25 and the Harvard Trauma Questionnaire

This study sought to translate and validate the Hopkins Symptom Checklist-25 (HSCL) and the Harvard Trauma Questionnaire (HTQ) in a Tibetan population. Translated questionnaires were administered to 57 Tibetan survivors of torture/human rights abuses living in the United States and receiving services in a torture treatment program. Participants were evaluated to determine if they met criteria for major depressive episode, generalized anxiety disorder, or posttraumatic stress disorder (PTSD). Coefficient alpha for the HSCL Anxiety subscale (.89), Depression subscale (.92), and the HTQ (.89) were high. Diagnostic accuracy using receiver operating characteristic curve analysis generated good classification accuracy for anxiety (.89), depression (.92), and PTSD (.83). However, although sensitivity and specificity for HSCL subscales were quite high, the HTQ generated low sensitivity (.33), partly because of a low rate of PTSD. Results support the reliability and validity of the HSCL but suggest further study of the HTQ with this population is required.     

Reliability, validity and normative data for the Danish Beck Youth Inventories

This study examines reliability and validity and establish Danish norms for the Danish version of the Beck Youth Inventories (BYI) ( Beck, Beck & Jolly, 2001 ), which consists of five self-report scales; Self-Concept (BSCI), Anxiety (BAI), Depression (BDI), Anger (BANI) and Disruptive Behavior (BDBI). A total of 1,116 school children and 128 clinical children, aged 7–14, completed BYI. Internal consistency coefficients were high. Most test-retest correlations were >0.70. A test-retest difference was found for BAI. Exploratory and confirmatory factor analysis indicated that the five factor structure of the instrument was justified. The BSCI, BAI and BDI discriminated moderately between the norming sample and the clinical group, and the latter group included more children who exceeded the 90th percentile of the norming sample. Diagnostic groups scored higher on relevant scales than norms. Only BSCI and BDI differentiated between diagnostic groups. The BYI showed acceptable internal consistency and test-retest stability, except for BAI. The BYI did not adequately differentiate between internalizing disorders.     

THE SILENCING THE SELF SCALE: Schemas of Intimacy Associated With Depression in Women

The Silencing the Self Scale (STSS), derived from a longitudinal study of clinically depressed women, measures specific schemas about how to make and maintain intimacy hypothesized to be associated with depression in women. To assess its psychometric properties, the STSS was administered with the Beck Depression Inventory (BDI) to three samples of women: college students ( n = 63), residents in battered women's shelters ( n = 1401, and mothers ( n = 270) (of 4-month-old infants) who abused cocaine during pregnancy. The STSS had a high degree of internal consistency and test-retest reliability and was significantly correlated with the BDI in all three samples.     

The German Version of the Emotion Awareness Questionnaire for Children and Adolescents: Associations with Emotion Regulation and Psychosocial Adjustment

The psychometric properties of the Beck Inventory (BI), a revised, copyrighted version of the Beck Depression Inventory (BDI), were investigated in 204 university students. Two-week test-retest reliability was .90, coefficient alpha was .87, concurrent validity using the BDI as the criterion was .94, and the correlation between level of depression as measured by the two instrument was .86. The mean score on the DI was significantly but only one-half point lower than that on the BDI. Individual items were all highly and significantly correlated, but items. Depression was not significantly related to demographic variables.     

The Beck Inventory: psychometric properties in university students

The psychometric properties of the Beck Inventory (BI), a revised, copyrighted version of the Beck Depression Inventory (BDI), were investigated in 204 university students. Two-week test-retest reliability was .90, coefficient alpha was .87, concurrent validity using the BDI as the criterion was .94, and the correlation between level of depression as measured by the two instruments was .86. The mean score on the BI was significantly but only one-half point lower than that on the BDI. Individual items were all highly and significantly correlated, but a significantly lower BI mean score occurred on the Sadness, Suicidal Ideas and Insomnia items. Depression was not significantly related to demographic variables.     

A Norwegian adaptation of the Penn State Worry Questionnaire: factor structure, reliability, validity and norms

A Norwegian version of the Penn State Worry Questionnaire (PSWQ) was administered to 304 undergraduate students together with the Beck Depression Inventory (BDI), the State-Trait Anxiety Inventory (STAI) and the Maudsley Obsessive Compulsive Inventory (MOCI). The PSWQ was also administered to a community sample comprising 879 subjects, together with the Beck Anxiety Inventory (BAI), the Beck Depression Inventory II (BDI II) and the White Bear Suppression Inventory (WBSI). Structural equation modeling showed that a three-factor solution of the PSWQ gave the best goodness of fit. The Norwegian version of the PSWQ demonstrated adequate psychometric properties in terms of reliability and validity in both samples. Females scored higher than males on PSWQ.     

Measurement of depression: Comparison between self-reports and clinical assessments of depressed outpatients

Agreement among several depression scales was investigated as regard the relative influences of administration mode (self-rating or clinical rating) and scale content. The Beck Depression Inventory (BDI), the Self-Rating Depression Scale (SDS), the Hamilton Rating Scale for Depression (HRSD), and three corresponding scales with identical structure and content but the alternative administration mode were administered to 47 outpatients with diagnoses of DSM-III major depression disorders. Correlations between the total scores and the degrees of association between corresponding items of different scales were calculated. The results suggest that differences in content contribute more to inter-scale discrepancy than differences in administration mode. The implications for the evaluation of outpatients with major depression are discussed.     

Psychometric properties of the Reynolds Child Depression Scale in community and clinical samples

The factor structure of the Reynolds Child Depression Scale (RCDS; Reynolds, 1989), analyzed by confirmatory factor analysis and the scale's psychometric characteristics in a sample of 315 participants (140 boys and 175 girls) and a clinical sample of 62 participants (37 boys and 25 girls) between 10 and 12 years old, are presented. Two models are tested with confirmatory factor analysis: a one-factor model and a five-factor model. Both models show a good fit, but the one-factor model was chosen because it is the most parsimonious. The reliability coefficient ranged from .87 (at test) to .89 (at retest) in the community sample, and was .90 in the clinical sample (at test). Test-retest reliability was .66 in the community sample. Concurrent validity with other self-reports that measure depressive symptomatology was high, both in the community sample (.76) and the clinical sample (.71). There were no significant sex differences but there were differences due to age (school grade).     

A study of the psychometric properties of the Beck Depression Inventory‐II,the Montgomery and Åsberg Depression Rating Scale,and the Hospital Anxiety and Depression Scale in a sample from a healthy population

The objective of this study is to evaluate internal consistency and psychometric properties of the Hospital Anxiety and Depression Scale (HADS), the Beck Depression inventory‐II (BDI‐II) and the Montgomery and Åsberg Depression Rating Scale (MADRS) for screening for major depressive episode (MDE) in a selected sample from a healthy population. Participants answered the BDI‐II and the HADS questionnaires and were interviewed with MADRS. The Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (DSM)‐IV Axis I Disorders‐Clinician Version (SCID‐CV) was used to diagnose MDE. Current MDE was diagnosed in 20 (6%) of the 357 participants. All three scales including the depression sub‐scale for HADS had high area under the receiver operating characteristics curve (ROC) (AUC) (0.84–0.87), and internal consistency was also high for all scales (0.75–0.89). Optimal cut‐off for MDE was ≥ 12 for BDI‐II, MADRS ≥ 8, HADS total ≥ 9, and HADS‐D ≥ 4, which all resulted in sensitivities = 85% and specificities > 78%. Diagnostic accuracy was low on all depression scales (Cohen's kappa = 0.20–0.40). Reports of the properties of depression scales in a healthy population are limited. We found BDI‐II, HADS and MADRS to be acceptable as screening instruments for MDE in a selected sample from healthy population with recommend cut‐offs as mentioned above.     

Evaluating depression severity and remission with a modified Beck Depression Inventory

In an attempt to improve assessment of recovery from depression, a modified Beck Depression Inventory (mBDI) was created that permits endorsement of positive feelings in addition to depressive symptoms. In both normal and clinical samples, the mBDI showed evidence of reliability for measuring varying degrees of depression. In comparison to the original BDI, the mBDI did not significantly improve differentiation in depression severity among depressed individuals and assessment of remission of depressive symptoms. However, the mBDI was significantly better than the original BDI in detecting differences in depression level when overall depression severity was low. Clinical implications for evaluating remission of depression are discussed.     

A Hmong Adaptation of the Beck Depression Inventory

We developed the Hmong Adaptation of the Beck Depression Inventory (HABDI) and evaluated the instrument's psychometric characteristics. Also examined was the relationship between depression and demographic variables such as age, sex, length of stay in America, English-speaking ability, and social support in Hmong refugees. One hundred twenty-three Hmong living in Fresno County, between the ages of 18 and 66, participated in the study. The new measure demonstrated a high coefficient alpha (.93), and test-retest reliability (.92), and a significant mean score difference between the nondepressed and the depressed groups. Individual items were distributed evenly and correlated highly with the total depression score. The HABDI correctly identified 94% of depressed and 78% of nondepressed in the Hmong sample. The results suggest that quality of social support and years of education play important roles in buffering Hmong refugees against depression, whereas length of stay in America and number of social supports do not.     

Validation of the Beck Depression Inventory-II in a low-income African American sample of medical outpatients

The psychometric properties of the Beck Depression Inventory-II (BDI-II) are well established with primarily Caucasian samples. However, little is known about its reliability and validity with minority groups. This study evaluated the psychometric properties of the BDI-II in a sample of low-income African American medical outpatients (N=220). Reliability was demonstrated with high internal consistency (.90) and good item-total intercorrelations. Criterion-related validity was demonstrated. A confirmatory factor analysis supported a hierarchical factor structure in which the BDI-II reflected 2 first-order factors (Cognitive and Somatic) that in turn reflected a second-order factor (Depression). These results are consistent with previous findings and thus support the use of the BDI-II in assessing depressive symptoms for African American patients in a medical setting.     

Depression Following Traumatic Brain Injury: The Validity of the CES-D as a Brief Screening Device

The validity, reliability, and factor structure of the Center for Epidemiological Studies-Depression Scale (CES-D) was examined with 253 patients seen for neuropsychological evaluation following traumatic brain injury (TBI). All patients completed the CES-D; 31 also completed the Beck Depression Inventory (BDI) and 17 completed the Minnesota Multiphasic Personality Inventory-II (MMPI-II). The CES-D demonstrated good concurrent, construct validity, significantly correlating with the BDI (r = .673, p < .0001) and the MMPI-II (Depression Scale T score r = .536, p = .027). The CES-D also demonstrated good internal consistency (coefficient alpha = .8195) and split-half reliability (Spearman–Brown r = .8284). Principal components factor analysis with varimax rotation resulted in a four-factor solution that accounted for 56.01% of the variance. The factor structure differed from the originally reported factor structure, and indicated that somatic difficulties were strongly associated with dysphoric affect in TBI patients. The CES-D is a valid and reliable screening instrument for use with TBI patients.     

Test-retest reliability and standard error of measurement for the test of variables of attention (T.O.V.A.) with healthy school-age children

Test-retest reliability of the Test of Variables of Attention (T.O.V.A.) was investigated in two studies using two different time intervals: 90 min and 1 week (2 days). To investigate the 90-min reliability, 31 school-age children (M = 10 years, SD = 2.66) were administered the T.O.V.A. then read ministered the test 90 min afterward. Significant reliability coefficients were obtained across omission (.70), commission (.78), response time (.84), and response time variability (.87). For the second study, a different sample of 33 school-age children (M = 10.01 years, SD = 2.59) were administered the test then read ministered the test 1 week later. Significant reliability coefficients were obtained for omission (.86), commission (.74), response time (.79), and response time variability (.87). Standard error of measurement statistics were calculated using the obtained coefficients. Commission scores were significantly higher on second trials for each retest interval.     

Depressive symptoms in Swedish adolescents

This study examined the prevalence of self-reported depressive symptoms in a Swedish urban school sample (n=547) aged 13 to 18 years using the Beck Depression Inventory (BDI). The data obtained were examined with respect to sex and age differences and compared with a clinical sample of adolescents hospitalized because of psychiatric disturbances. The results indicated a strong preponderance of depressive symptoms among girls in the school sample, in particular for the severe symptom level. Eight percent of subjects reported depressive symptoms sufficiently high to be classified as a moderate, and 2% as a severe, level of depression. Factor analysis yielded four factors representing dysphoric mood, social activity, relationship, and food-related dimensions. The BDI showed a high internal consistency, and test-retest reliability calculated for a 2-week and a 2-month interval revealed strong correlations. The means of total scores on the BDI for the clinical sample were significantly higher than for those in the school sample.     

Sex differences in the expression of depression in adolescents

The purpose of the present study is to examine the patterns of depressive response of adolescents on The Beck Depression Inventory (BDI). Subjects, who were registered at the Western Québec Regional School Board (Grades 7–12), completed the BDI in the context of intact classes. Out of 1015 subjects, 249 (152 females, 97 males) met the cut-off score of 15 and above on the BDI, and were retained for the study. Sixty-three percent were francophone and 37 percent were anglophone. Ages ranged from 12 to 17 years. Results did not reveal any difference in the BDI scores as a function of either sex, age, or language. However, a significant discriminant function was obtained from subjects' responses that correctly differentiates depressed males from depressed females in 67.8% of the cases. These differential patterns of depressive responding are compared with those observed in depressed college students and adult psychiatric patients, and discussed in light of the literature on adolescent depression.This is an extended version of a poster paper presented at the 48th annual meeting of the Canadian Psychological Association, Vancouver, June 1987.     

Self-disgust mediates the relationship between dysfunctional cognitions and depressive symptomatology

Disgust has been linked to several psychopathologies, although a role in depression has been questioned. However, it has recently been proposed that rather than general disgust sensitivity, disgust directed toward the self (self-disgust) may influence the development of depression, providing a causal link between dysfunctional cognitions and depressive symptomatology. This possibility was examined by developing a scale to measure self-disgust (the Self-Disgust Scale; SDS) and then using mediator analysis to determine if self-disgust was able to explain the relationship between dysfunctional cognitions (measured with the use of the Dysfunctional Attitudes Scale) and depressive symptomatology (measured with the use of the Beck Depression Inventory and the Depression, Anxiety and Stress Scale). The developed SDS was found to exhibit a high level of internal consistency, test-retest reliability, and concurrent validity. Principal-components analysis revealed two factors to underlie responses to SDS items: the 'Disgusting self,' concerned with enduring, context independent aspects of the self, and 'Disgusting ways,' concerned with behavior. Self-disgust was found to mediate the relationship between dysfunctional cognitions and depressive symptomatology, demonstrating for the first time that self-disgust plays a role in depression.     

Depression in a Cancer Patient Population

The main goal of this study was to examine depression and its components in cancer patients as compared with healthy control subjects and psychiatric inpatients. The participants were 54 cancer patients (28 females with breast cancer, 26 males with prostate cancer), 59 healthy controls (33 females, 26 males), and 75 psychiatric patients (27 females, 48 males). Participants were administered the Beck Depression Inventory (BDI) and the State Trait Personality Inventory (STPI) Depression scales. Cancer patients had higher overall depression scores than did healthy controls as measured by BDI, but the difference was due primarily to the significantly higher scores of the cancer patients on the BDI Somatic–Performance subscale. No differences were found on the BDI Cognitive–Affective subscale. Cancer patients also scored significantly higher than healthy controls on the State-Trait Personality Inventory (STPI) State Depression (S-Dep) scale because of higher Euthymia subscale scores. The psychiatric inpatients scored significantly higher than the other groups on all measures of depression. The findings of this study suggest that cancer patients may be erroneously labeled as depressed because of somatic–performance difficulties they may experience, which are similar to symptoms of depressed individuals. In addition, it is essential to delineate the various components of depression in evaluating cancer patients.     

The relationship of marital satisfaction and social support to depressive symptomatology

The relationship between depressive symptomatology, as measured by the short-form Beck Depression Inventory (BDI), and two social support variables was assessed. Based on a sample of 131 married men and 136 married women, the results indicated that the quality of the marital relationship and the frequency of positive social contact with adults other than the spouse were significantly related to depressive symptomatology for both men and women. These two variables accounted for 16% of the variance in BDI scores. Further, analyses of risk for high BDI scores showed that individuals having the least support were 13 times more likely to be in the high-BDI group than individuals with the highest levels of social support. These results suggest that social isolation and marital discord are related to high BDI scores among married adults.     

Rasch analysis of a simplified Beck Depression Inventory

Depression is one of the most clinically relevant mood disorders, and many assessment instruments have been developed to measure it. Probably the most frequently used instrument is Beck’s Depression Inventory (BDI). The simplified BDI (BDI-S) is a more efficient version of the BDI that has been shown to be no less reliable or valid. As the BDI-S has not yet been subjected to rigorous tests of Item Response Theory, it is the aim of the present paper to conduct such an analysis using the Rasch model. This study subjected a simplified version of the BDI consisting of 20 items (BDI-S20) to a Rasch analysis in a sample of N = 5,035 participants. The scale, minus one misfitting item (BDI-S19), yielded a good approximation to Rasch assumptions. Moderate differential item functioning (DIF) was present. It is concluded that the BDI-S19 is an internally valid instrument for assessing depression, although some room for improvement exists.
