Numerous studies have focused on the factor structure of the Beck Depression Inventory (BDI) because its underlying structure, once identified, may improve our conceptualizations of the cognitive processes in depression. These studies have produced a wide range of interpretations for the BDI, yet the replicability of these factor solutions across(More)
The Eating Disorders Inventory (EDI) is a promising new measure of the cognitive and behavioral characteristics of anorexia nervosa and bulimia, although the replicability of its eight subscales has not been evaluated. Therefore, a factor analysis of the EDI was carried out that used the FACTOREP procedure. The results, using non-patient responses, did not(More)
The Beck Depression Inventory-II (BDI-II) is widely used for assessing depression in neurorehabilitation. Given the concern that the somatic items might be misleading, we examined its factor structure in 353 inpatients. Exploratory factor analysis was undertaken to compare two- to five-factor solutions. Confirmatory factor analysis was then used to test the(More)
The Internal-External control scales of Rotter and Levenson, and the Social Desirability scale of Marlowe and Crowne were completed by 71 male and 85 female students. Factor analysis clearly confirmed the three-factor structure underlying Levenson's questionnaire, while further analyses revealed close agreement with her findings on scale characteristics and(More)
'Weight pathology'--defined by Kalucy et al. (1977) as 'deviations in weight, shape, eating behaviour and activity'--has been hypothesized to be unduly common in families with anorexia nervosa. It was investigated in this study by means of questionnaires evaluating both weight history and attitudes towards weight-related matters in 58 mothers of anorexia(More)
Data is presented from a sample drawn from the general Fiji population to standardise the Impact of Events Scale (IES) and to prepare percentile tables from which validating comparisons could be made with the scores of two target groups from a previous Fiji study. Detailed statistical analyses gave strong support for a general factor and marginal support(More)
Norms are presented for the 20-item version of the General Health Questionnaire (GHQ 20) that were obtained from a non-clinical group of the Fiji population. The data was required to give meaning to the results that had been obtained from a group of former hostages and the families of hostages that were still in custody. With the omission of two items, the(More)
While knowledge of the biomedical factors in diabetes has grown in a steady and systematic fashion over the past 60 years, attempts to define, measure, and understand the relevant psychological constructs have only begun recently. In particular, there is need for psychometrically sound tests to tap these dimensions. This study examined the psychometric(More)
Some effects of using inappropriate criteria for sufficiency of factors are discussed, and examples from the literature used to show how procedures leading to the rotation of large numbers of factors may result in fragmentation and difficulty in interpretation. Analyses of two psychometrically equivalent matrices containing an imposed scale structure led to(More)
