Psychiatric comorbidities, particularly anxiety-related pathologies, are often observed in dizzy patients. The Hospital Anxiety and Depression Scale (HADS) is a widely used self-report instrument used to screen for anxiety and depression in medical outpatient settings. The purpose of this study was to assess the factor structure, internal consistency and convergent validity of the HADS in an unselected group of patients with dizziness. The HADS and the Dizziness Handicap Inventory (DHI) were administered to 205 dizzy patients. An exploratory factor analysis was conducted and indicated a 3-factor structure, inconsistent with the 2-subscale structure (i.e. anxiety and depression) of the HADS. The total scale was found to be internally consistent, and convergent validity, as assessed using the DHI, was acceptable. Overall findings suggest that the HADS should not be used as a tool for psychiatric differential diagnosis, but rather as a helpful screener for general psychiatric distress in the two domains of psychiatric illness most germane in dizzy patients.

Abstract Background Anxiety and depression symptoms are common among cardiac patients. The Hospital Anxiety and Depression Scale (HADS) is frequently used to measure symptoms of anxiety and depression; however, no study on the validity and reliability of the scale in Danish cardiac patients has been done. The aim, therefore, was to evaluate the psychometric properties of HADS in a large sample of Danish patients with the four most common cardiac diagnoses: ischemic heart disease, arrhythmias, heart failure and heart valve disease. Methods The DenHeart study was designed as a national cross-sectional survey including the HADS, SF-12 and HeartQoL and combined with data from national registers. Psychometric evaluation included analyses of floor and ceiling effects, structural validity using both exploratory and confirmatory factor analysis and hypotheses testing of convergent and divergent validity by relating the HADS scores to the SF-12 and HeartQoL. Internal consistency reliability was evaluated by Cronbach’s alpha, and differential item functioning by gender was examined using ordinal logistic regression. Results A total of 12,806 patients (response rate 51%) answered the HADS. Exploratory factor analysis supported the original two-factor structure of the HADS, while confirmatory factor analysis supported a three-factor structure consisting of the original depression subscale and two anxiety subscales as suggested in a previous study. There were floor effects on all items and ceiling effect on item 8. The hypotheses regarding convergent validity were confirmed but those regarding divergent validity for HADS-D were not. Internal consistency was good with a Cronbach’s alpha of 0.87 for HADS-A and 0.82 for HADS-D. There were no indications of noticeable differential item functioning by gender for any items. Conclusions The present study supported the evidence of convergent validity and high internal consistency for both HADS outcomes in a large sample of Danish patients with cardiac disease. There are, however, conflicting results regarding the factor structure of the scale consistent with previous research. Trial registration ClinicalTrials.gov: NCT01926145.

Objective: to adapt to Portuguese, of Portugal, the Depression, Anxiety and Stress Scales, a 21-item short scale (DASS 21), designed to measure depression, anxiety and stress. Method: After translation and back-translation with the help of experts, the DASS 21 was administered to patients in external psychiatry consults (N=101), and its internal consistency, construct validity and concurrent validity were measured. Results: The DASS 21 properties certify its quality to measure emotional states. The instrument reveals good internal consistency. Factorial analysis shows that the two-factor structure is more adequate. The first factor groups most of the items that theoretically assess anxiety and stress, and the second groups most of the items that assess depression, explaining, on the whole, 58.54% of total variance. The strong positive correlation between the DASS 21 and the Hospital Anxiety and Depression scale (HAD) confirms the hypothesis regarding the criterion validity, however, revealing fragilities as to the divergence between theoretically different constructs.

AbstractThe Revised Child Anxiety and Depression Scale (RCADS) is a 47-item self-report measure intended to assess children's symptoms corresponding to selected DSM-IV anxiety and major depressive disorders. The scale comprises six subscales (e.g., Separation Anxiety Disorder; Social Phobia; Obsessive Compulsive Disorder; Panic Disorder; Generalised Anxiety Disorder; and Major Depressive Disorder). To date, only one normative study of youth has been published with results providing strong initial support for the reliability and validity of this new measure (Chorpita, Yim, Moffitt, Umemoto, & Francis, 2000). The present investigation provides additional psychometric data derived from an Australian sample comprising 405 youth aged 8 to 18 years. In general, the data were found to be consistent with those reported in the initial normative study. Internal consistency for the overall scale and its subscales was found to be adequate. Good convergent validity was demonstrated through moderate to strong correlations between the subscales of the RCADS with scores on the Revised Children's Manifest Anxiety Scale (RCMAS) and the Children's Depression Inventory (CDI). Confirmatory factor analysis suggested reasonable fit for the six-factor model by Chorpita et al. (2000). Notwithstanding the need for additional validation, it is concluded that the RCADS is a promising instrument for use in both clinical and research settings.

<p><strong>Objective:</strong> This study investigated symptoms of anxiety and depression in relatives of patients admitted in the Intensive Care Unit and determined whether these symptoms were associated to the seriousness of the patients’ condition.</p><p><strong>Metodology:</strong> A total of 102 patients’ relatives were surveyed<br />during the study. They were given a self-report questionnaire in order to assess demographic data, anxiety and depression symptoms. The symptoms of anxiety and depression were evaluated with the Hospital Anxiety and Depression Scale (hads). Patient’s condition was evaluated with a.p.a.ch.e ii Score.</p><p><strong>Results:</strong> More than 60% of patients’ relatives presented severe symptoms of anxiety and depression. No relation was found between symptoms of anxiety and depression of the relatives of patients and patients’ condition of health. On the<br />contrary, these feelings used to exist regardless of the seriousness of patient’s condition.</p><p><strong>Conclusions:</strong> The assessment of these patients is recommended in order serious problems of anxiety<br />and depression to be prevented. </p>

BackgroundThe Hospital Anxiety and Depression (HAD) rating scale is a commonly used questionnaire. Former studies have given inconsistent results as to the psychometric properties of the HAD scale.AimsTo examine the psychometric properties of the HAD scale in a large population.MethodAll inhabitants aged 20–89 years (n=92 100) were invited to take part in The Nord-Tr⊘ndelag Health Study, Norway. A total of 65 648 subjects participated, and only completed HAD scale forms (n=51 930) formed the basis for the psychometric examinations.ResultsPrincipal component analysis extracted two factors in the HAD scale that accounted for 57% of the variance. The anxiety and depression sub-scales shared 30% of the variance. Both sub-scales were found to be internally consistent, with values of Cronbach's coefficient (a) being 0.80 and 0.76, respectively.ConclusionsBased on data from a large population, the basic psychometric properties of the HAD scale as a self-rating instrument should be considered as quite good in terms of factor structure, intercorrelation, homogeneity and internal consistency.

Background: The present study explored the reliability, validity, and factor structure of a modified version of the Moral Disengagement Scale (MDS), which comprehensively assesses proneness to disengage from different forms of conduct specific to Australian adolescents. Methods: A sample of 452 students (Mage = 12.79; SD = 1.93) completed the modified MDS and the Australian Self-Report Delinquency Scale. A multistep approach was used to evaluate the factor structure of the MDS. The sample was divided into exploratory (n = 221) and cross-validation samples (n = 231). Principal component analysis was conducted with the exploratory sample and multiple factor solutions compared to determine the optimal factor structure of the modified MDS. The final factor solution was confirmed in the cross-validation sample using confirmatory factor analysis. Internal consistency of the final scale and convergent validity with the delinquency questionnaire was also assessed. Results: Analyses resulted in a 22-item MDS for use in Australia, with four factors mapping onto the four conceptual categories of moral disengagement. The individual subscales demonstrated adequate to good internal consistency, and the total scale also demonstrated high internal consistency (α = 0.87). Convergent validity of the scale was established. Conclusions: The 22-item Australian MDS is a reliable and valid instrument for use within an Australian population.
