Death Depression

The purpose of this study was to translate Templer et al.'s Death Depression Scale-Revised into Spanish and to evaluate its psychometric properties in a sample of Spanish students. The Death Depression Scale-Revised is a 21-item Likert format questionnaire that could also be applied in true-false format. The Spanish form of the scale was answered by 342 psychology and nursing undergraduates, obtaining a Cronbach's coefficient alpha of .90, and test-retest correlation over four weeks was .87. The first solution of a principal components analysis yielded four significant factors with Eigenvalues greater than one that accounted for 59.3% of the variance. These factors were called, respectively: anergia and vacuum, death sadness, others' death, and anhedonia. The results show that the Spanish adaptation of the Death Depression Scale-Revised has an adequate internal consistency, criterion-validity, and a coherent factorial structure.

Trust Scale

The purpose of this study was to examine the psychometric properties of the Specific Interpersonal Trust scale of Johnson-George and Swap in Korean samples as a part of the process of providing an exemplary tool for intercultural studies of trust. A translated version of the original scale was administered to 337 university students (157 males, 180 females) in Seoul, Korea. Data were subjected to a principal components analysis and a confirmatory factor analysis. In principal components analysis for the Korean sample ( n = 167), three factors were identified and labeled: Overall Trust (Cronbach α=.89), Emotional Trust (Cronbach α = .88), and Reliableness (Cronbach α=.84). A confirmatory factor analysis ( n=170) showed that the three-factor model was valid for the sample (χ2/ df= 1.78, RMR=.06, RMSEA = .07, TLI=.92, CFI=.93). Internal consistency reliability and factorial validity were satisfactory in the case of the Korean sample. The Korean version of the Specific Interpersonal Trust Scale made good use of three factors of trust and appeared to be valid without sex differences, while the original scale distinguished the Males subscale from the Females subscale. Implications and limitations of this study were discussed.

Death Depression

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 α 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.

BackgroundExpert clinical judgement combines technical proficiency with humanistic qualities.AimsTo test the psychometric properties of questionnaires to assess the humanistic qualities of working with colleagues and relating to patients using multisource feedback.MethodAnalysis of self-ratings by 347 consultant psychiatrists and ratings by 4422 colleagues and 6657 patients.ResultsMean effectiveness as rated by self, colleagues and patients, was 4.6, 5.0 and 5.2 respectively (where 1=very low and 6=excellent). The instruments are internally consistent (Cronbach's alpha > 0.95). Principal components analysis of the colleague questionnaire yielded seven factors that explain 70.2% of the variance and accord with the domain structure. Colleague and patient ratings correlate with one another (r=0.39, P<0.001) but not with the self-rating. Ratings from 13 colleagues and 25 patients are required to achieve a generalisability coefficient (Eρ2) of 0.75.ConclusionsReliable 360-degree assessment of humane judgement is feasible for psychiatrists who work in large multiprofessional teams and who have large case-loads.

Data taken from the blood of 262 patients diagnosed for malabsorption, elective cholecystectomy, acute cholecystitis, infectious hepatitis, liver cirrhosis, or chronic renal disease were analyzed with three numerical taxonomy (NT) methods : cluster analysis, principal components analysis, and discriminant function analysis. Principal components analysis revealed discrete clusters of patients suffering from chronic renal disease, liver cirrhosis, and infectious hepatitis, which could be displayed by NT clustering as well as by plotting, but other disease groups were poorly defined. Sharper resolution of the same disease groups was attained by discriminant function analysis.
