Comparison of the Hamilton Depression Rating Scale and the Geriatric Depression Scale: detection of depression in dementia patients.

The present longitudinal prospective study compared results from the Geriatric Depression Scale with those from the Hamilton Depression Rating Scale for 30 dementia patients. The criterion measure was presence of depression as indicated by the psychiatric diagnosis. The psychiatrist and physician's assistant made the Hamilton ratings while the psychology staff administered the Geriatric Depression Scale. The two measures were statistically unrelated from Times 1 and 2 (rs = .26 and .41). Eleven (37%) patients were depressed and nine received antidepressant medications. Sensitivity ratings were 82% and 9%, respectively, and specificity ratings were 88% and 92%, respectively. Possible explanations for the success of the Geriatric Depression Scale and lack of success of the Hamilton ratings in detecting depression in this population are discussed.     

The Spanish form of the Death Depression Scale

The aims were to estimate the psychometric properties of the Spanish form of the Death Depression Scale and to compare these with those of other versions of the scale. The Death Depression Scale was administered to a sample of 218 Spanish student nurses, together with Templer's Death Anxiety Scale and measures of general depression and anxiety. The Cronbach coefficient a was 83, and a 4-wk. test-retest correlation was .87. The correlations with scores on other tests were similar to those obtained in former studies. After applying a principal components factor analysis with varimax rotation, four factors with eigenvalues greater than one were identified. These factors were labeled Death Sadness, Death Finality, Meaninglessness of Life, and Feeling of Loss. Generally speaking, the results favour consideration of the Death Depression Scale as a valid and reliable means of assessment among Spanish-speaking individuals.     

Psychometric evaluation of the Geriatric Depression Scale and the Zung Self-Rating Depression Scale using an elderly community sample

In this study the psychometric properties of the Geriatric Depression Scale (GDS) and the Zung Self-Rating Depression Scale (SDS) were evaluated and compared, using a relatively large elderly community sample. The GDS generally performed well, replicating earlier findings from a different population. Also, as hypothesized, the SDS, which has a multiple-choice format, had a higher non-completion rate than the GDS, which has a true-false format. Finally, no significant differences between the responses of young-old and old-old subjects were observed.     

Model stability of the 15-item Geriatric Depression Scale across cognitive impairment and severe depression

The 15-item Geriatric Depression Scale (GDS) is used in a wide variety of clinical and research settings. The study's purpose was to further establish the validity of the 15-item GDS by exploring the underlying factor structure in a healthy, nondemented sample of older adults and then analyzing whether this factor structure remained stable across a sample of demented individuals and a sample of individuals with a history of depression 6 months after discharge from an inpatient psychiatric setting. A 2-factor model fit the data best in the exploratory analyses. The 2 factors, Life Satisfaction and General Depressive Affect, found in the nondemented sample (r = .39) remained stable across cognitive impairment (r = .12) but merged into a 1-factor model in the psychiatric sample (r = .93). The results indicate that nondepressed older adults with poor life satisfaction may be identified as depressed on screening instruments such as the 15-item GDS.     

Depression and decision-making among intravenous drug users

Two short scales, the TCU Depression Scale and the TCU Decision-making Scale, were psychometrically evaluated in a sample of 145 intravenous drug users. Coefficient alpha reliabilities were .78 for the 6-item TCU Depression Scale and .77 for the 9-item TCU Decision-making Scale. Concurrent validity of the former scale was assessed by correlating scores with those on the Beck Depression Inventory, r = .75. Based on the Beck Depression Inventory Clinical cutoff scores, 83% of the sample showed some depression, with 23% severely depressed, 39% moderately depressed, and 21% mildly depressed. Individuals scoring higher on depression on both tests tended to score lower on decision-making. Significant demographic associations of age, gender, education, and race-ethnicity were found for the depression and decision-making scales. More depression was noted for women, those younger, white, and having less education. Older and more educated intravenous drug users tended to score higher on decision-making. Validity for the depression and decision-making scales was assessed by examining correlations with behaviors. Significant positive correlations were found between depression scores and intravenous use of cocaine only, heroin and cocaine combined, and heroin only. Also, intravenous use of cocaine only and of cocaine and heroin combined were negatively related to decision-making. AIDS sex-risky behavior was positively correlated with depression and negatively correlated with decision-making.     

Subjective and objective measures of quality of life have different predictors for people with schizophrenia

This study investigated the relationship between subjective and objective quality of life and assessed predictors in people with schizophrenia. The study population consisted of 99 stabilized outpatients with schizophrenia (DSM-IV) who had been regularly receiving outpatient treatment at the Department of Psychiatry, The Tokushima University Hospital. Subjective and objective quality of life were estimated using the Schizophrenia Quality of Life Scale and the Quality of Life Scale, respectively. Psychiatric symptoms were also measured with the Brief Psychiatric Rating Scale and the Calgary Depression Scale for Schizophrenia. Scores on the Schizophrenia Quality of Life Scale Motivation and Energy scales significantly correlated with the Quality of Life Scale total scores -.40 (p <.001), and with the scores on Interpersonal Relations subscale -.42 (p <.001), Instrumental Role subscale -.28 (p = .005), Intrapsychic Foundations subscale -.39 (p<.001), and Common Objects and Activities subscale -.25 (p =.014). The Schizophrenia Quality of Life Scale Psychosocial scale significantly correlated with only the Quality of Life Scale total score -.20 (p =.05), and there was no significant correlation between the scores on the Schizophrenia Quality of Life Scale Symptoms and Side-effects scales and the Quality of Life Scale. Stepwise regression analyses showed that the Calgary Depression Scale for Schizophrenia score was the most important predictor of each scale of the Schizophrenia Quality of Life Scale, and the Brief Psychiatric Rating Scale Negative Symptoms score was the most important predictor of the Quality of Life Scale total score and each subscale. These results suggest that subjective and objective quality of life have different predictors and should be considered as separate and complementary outcome variables.     

Factor structure of the Chinese version of the Geriatric Depression Scale

Depression is common in patients following stroke and has been found to be related to the degree of functional disability, recovery and engagement in rehabilitation. Consequently, screening for depression is crucial in this group in order to facilitate the delivery of appropriate psychological support. The current study sought to determine key psychometric properties of the Chinese version of the Geriatric Depression Scale (GDS) in this group. Three versions of the GDS were evaluated, these being the 30-item original measure (GDS-30), the short-form version comprising 15 items (GDS-SF) and a recently developed innovative four-item version (GDS-4). Confirmatory factor analysis revealed the GDS-30 and GDS-SF to offer an acceptable fit to data suggesting utility of these measures for screening. However, the GDS-4 offered a poor fit to the data, suggesting this measure was an inadequate measure of depression in this clinical group. Further, though GDS-30 and GDS-SF measures revealed good internal consistency, the performance of the GDS-4 was marginal. However, all GDS-derived measures demonstrated excellent convergent and divergent validity. It is concluded that the GDS-30 is a useful and appropriate screening instrument in this group. Further, the GDS-SF shows promise in terms of development as a multidimensional measure of depression that may have predictive and outcome monitoring potential. The psychometric shortcomings of the GDS-4 strongly suggest that this measure is unsuitable for screening in this clinical group.     

Effect of instructional set on responses to the Geriatric Depression Scale

A community sample of elderly subjects (M age = 74 years) was randomly assigned to four variations in reference group instructions on the Geriatric Depression Scale (GDS). In one condition, subjects received no instructions as to reference group, which is the standard instructional format of the test. In the other three conditions, subjects were asked to compare themselves with one of three reference groups: age group peers, adults in general, or themselves at a younger age. Results indicated that the GDS is robust with respect to variation in reference group instruction.     

The Multidimensional Child and Adolescent Depression Scale: psychometric properties

Based on previous factor analyses of child and adolescent depression inventories, the following eight basic dimensions were identified, i.e., Pessimism, Weak Concentration, Sleep Problems, Anhedonia, Fatigue, Loneliness, Low Self-esteem, and Somatic Complaints. Each dimension was assessed by five items, so the Multidimensional Child and Adolescent Depression Scale has 40 brief statements answered on a 3-point intensity scale, i.e., None, Some, and A lot. The eight dimensions have good factorial validity and acceptable to good alpha and test-retest reliability, and good criterion-related validity using three self-report depression scales. The total scale score has from good to high coefficients of reliability and validity. The highest mean scores were on Fatigue and Anhedonia for Kuwaiti boys and girls, respectively, while the Loneliness subscale has the lowest mean score for both sexes. Girls attained significantly higher mean scores than boys for the total score as well as on all dimensions, with the exception of weak concentration. The scale has two compatible Arabic and English versions. It was designed to be useful in defining the profile of children's and adolescents' depression.     

自我韧性量表与Connor-Davidson韧性量表的应用比较

目的:考察自我韧性量表中文版的心理测量学指标,探讨其与Connor-Davidson韧性量表的关系,比较两者在中国人群中的应用效果。方法:在社区人群中施测自我韧性量表和Connor-Davidson韧性量表的中文版,以及自尊量表、生活满意度指数A问卷、大五人格问卷。结果:自我韧性量表中文版的内部一致性系数为0.77,略低于Connor-Davidson韧性量表。自我韧性量表与Connor-Davidson韧性量表的相关系数为0.61。在以自尊、生活满意度、大五人格为效标时,偏相关分析表明控制了Connor-Davidson韧性量表得分后,自我韧性量表与效标的相关未达到显著水平(除大五人格的外向性维度外);但控制了自我韧性量表得分后,Connor-Davidson量表与效标的相关仍达到显著水平(除开放性维度外)。结论:在我国人群的应用中,Connor-Davidson韧性量表优于自我韧性量表,是值得推广的韧性测量工具。     

Clinical cutoffs for the beck Depression inventory and the Geriatric Depression scale with older adult psychiatric outpatients

The present study developed new clinical cutoffs for the Beck Depression Inventory (BDI) and the Geriatric Depression Scale (GDS) with 59 older adult psychiatric outpatients. Maximum discrimination of a current major depressive episode resulted, with cutoff scores of 22 for the BDI and 16 for the GDS. Specifically, the following validity scores emerged for the BDI: sensitivity, 64%; specificity, 73%; positive predictive power, 75%; negative predictive power, 61%; and hit rate 68%. For the GDS the validity scores were as follows: sensitivity, 79%; specificity, 69%; positive predictive power, 77%; negative predictive power, 72%; and hit rate, 75%. Combined BDI and GDS scores did not result in improved prediction of a current major depressive episode as compared to the GDS alone. These results support the notion that the BDI and GDS are valid quick screening instruments in discriminating a current major depressive episode for older adult psychiatric outpatients.     

Clinical utility and validation of the Couple's Communicative Evaluation Scale

This study assessed the validity and clinical utility of a new test, the Couple's Communicative Evaluation Scale. With 24 couples from a variety of resources, e.g., churches, newspaper, and colleges, a discriminant analysis using the Dyadic Adjustment Scale, indicated that satisfied couples could be discriminated from issatisfied couples with 91-96% accuracy. Significant differences on the scale were found for means between 7 distressed and 16 nondistressed couples using the satisfaction/dissatisfaction cutoff score of 200 on the Dyadic Adjustment Scale and significant differences on the individual scales were found for means between 16 distressed and 31 nondistressed individuals using the satisfaction/dissatisfaction cutoff score of 100 on the Dyadic Adjustment Scale. Demographic variables, e.g., age, marriage length, were statistically significant. Scale scores were highly correlated with those on the Dyadic Adjustment Scale, indicating good validity. Using all 400 items, an alpha of .99 indicated good internal consistency for the verbal, nonverbal, and listening communication scores.     

Development of a Facebook Addiction Scale

The Bergen Facebook Addiction Scale (BFAS), initially a pool of 18 items, three reflecting each of the six core elements of addiction (salience, mood modification, tolerance, withdrawal, conflict, and relapse), was constructed and administered to 423 students together with several other standardized self-report scales (Addictive Tendencies Scale, Online Sociability Scale, Facebook Attitude Scale, NEO-FFI, BIS/BAS scales, and Sleep questions). That item within each of the six addiction elements with the highest corrected item-total correlation was retained in the final scale. The factor structure of the scale was good (RMSEA = .046, CFI = .99) and coefficient alpha was .83. The 3-week test-retest reliability coefficient was .82. The scores converged with scores for other scales of Facebook activity. Also, they were positively related to Neuroticism and Extraversion, and negatively related to Conscientiousness. High scores on the new scale were associated with delayed bedtimes and rising times.     

Rorschach responses in healthy, community dwelling older adults

Five predicted relationships between age and intellectual level and 16 Rorschach variables were examined through a cross-sectional analysis of 47 healthy, community-dwelling elderly men and women. Subjects were compared by age and intellectual level using gender, level of medication, and scores on the Geriatric Depression Scale (GDS) and the Geriatric Social Readjustment Questionnaire (GSRQ) as covariates. Screening tests for psychiatric and physical illness, recent life events, and hearing and vision loss were administered. In contrast to prior research suggesting changes in Rorschach scores with differences in age and intellectual level, only one significant difference was found for these variables. The data suggest that age and intellectual level may contribute less to Rorschach responses than was previously thought.

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.     

Psychometric Evaluation of the Japanese Version of the Elder Life Adjustment Interview Schedule for Depression

The Elder Life Adjustment Interview Schedule (ELAIS) was developed as an age- and culture-sensitive assessment device for depression and 9 environmental, behavioral, and health correlates (Schlatter et al., 1993, J. MARC Res. 1: 27–42). The psychometric adequacy of the ELAIS has been demonstrated with samples of elder Americans of Asian, Caucasian, and Native Hawaiian ancestry (Dubanoski et al., 1996, J. Clin. Gerospsychol. 2: 247–262). This study reports on the reliability and construct validity of a translated Japanese version. Participants were 55 community-dwelling elders living in the areas surrounding Maebashi, Japan. The ELAIS contains 14 scales of which 9 represent theoretical predictors of depression. The 2 Environmental Condition scales measure life events and social support. The 4 Behavioral Competency scales measure recreational activity, assertiveness, self-reinforcement, and perceived control. The 3 Health Factor scales measure perceived health, functional ability, and objective health. The 5 Other scales measure demographics, depression, life satisfaction, cognitive functioning, and response style. Results yielded acceptable internal consistency and stability reliability coefficients for all but 1 of the subscales on the ELAIS (informational social support). Construct validity support was found for the Depression scale and 6 theoretical predictors, including life events, recreational activity, assertiveness, self-reinforcement, functional ability, and objective health. Treatment and prevention implications for the cross-ethnic multivariate assessment of depression among elders are discussed.     

Reliability and validity of the Parenting Scale of Inconsistency

The purposes of the present study were to develop a Parenting Scale of Inconsistency and to evaluate its initial reliability and validity. The 12 items assess the inconsistency among parents' moods, behaviors, and attitudes toward children. In the primary study, 517 participants completed three measures: the new Parenting Scale of Inconsistency, the Parental Bonding Instrument, and the Depression Scale of the General Health Questionnaire. The Parenting Scale of Inconsistency had good test-retest reliability of .85 and internal consistency of .88 (Cronbach coefficient alpha). Construct validity was good as Inconsistency scores were significantly correlated with the Care and Overprotection scores of the Parental Bonding Instrument and with the Depression scores. Moreover, Inconsistency scores' relation with a dimension of parenting style distinct from Care and Overprotection suggested that the Parenting Scale of Inconsistency had factorial validity. This scale seems a potential measure for examining the relationships between inconsistent parenting and the mental health of children.     

The validity of the hospital anxiety and depression scale and the geriatric depression scale in Parkinson's disease

We assessed the concurrent validity of the Hospital Anxiety and Depression Scale (HADS) and the Geriatric Depression Scale (GDS) against the Hamilton Rating Scale for Depression (Ham-D) in patients with Parkinson's disease (PD). Forty-six non-demented PD patients were assessed by a neurologist on the Ham-D. Patients also completed four mood rating scales: the HADS, the GDS, the VAS and the Face Scale. For the HADS and the GDS, Receiver Operating Characteristics (ROC) curves were obtained and the positive and negative predictive values (PPV, NPV) were calculated for different cut-off scores. Maximum discrimination between depressed and non-depressed PD patients was reached at a cut-off score of 10/11 for both the HADS and the GDS. At the same cut-off score of 10/11 for both the HADS and the GDS, the high sensitivity and NPV make these scales appropriate screening instruments for depression in PD. A high specificity and PPV, which is necessary for a diagnostic test, was reached at a cut-off score of 12/13 for the GDS and at a cut-off score of 11/12 for the HADS. The results indicate the validity of using the HADS and the GDS to screen for depressive symptoms and to diagnose depressive illness in PD.     

A New Measure of Life Satisfaction: The Riverside Life Satisfaction Scale

The Satisfaction With Life Scale (Diener, Emmons, Larsen, & Griffin, 1985) has been the dominant measure of life satisfaction since its creation more than 30 years ago. We sought to develop an improved measure that includes indirect indicators of life satisfaction (e.g., wishing to change one's life) to increase the bandwidth of the measure and account for acquiescence bias. In 3 studies, we developed a 6-item measure of life satisfaction, the Riverside Life Satisfaction Scale, and obtained reliability and validity evidence. Importantly, the Riverside Life Satisfaction Scale retained the high internal consistency, test–retest stability, and unidimensionality of the Satisfaction With Life Scale. In addition, the Riverside Life Satisfaction Scale correlated with other well-being measures, Big Five personality traits, values, and demographic information in expected ways. Although the Riverside Life Satisfaction Scale correlated highly with the Satisfaction With Life Scale, we believe it improves the Satisfaction With Life Scale by appropriately increasing construct breadth and reducing the potential for bias.
