Screening for Hypochondriasis With the Illness Attitude Scales
2010
The Illness Attitude Scales (IAS; Kellner, 1986, 1987) may prove highly useful for the screening of hypochondriasis. We expected the IAS subscales to be equally as effective as the 7-item short version of the Whiteley Index (Whiteley-7; Fink et al., 1999), which has previously been shown to be useful in screening for somatoform disorders. We investigated participants of a German population (n = 1,575) and 61 patients with the Diagnostic and Statistical Manual of Mental Disorders (4th ed. [DSM-IV]; American Psychiatric Association, 1994) diagnosis of hypochondriasis. The Bodily Preoccupations (BP) subscale showed high sensitivity (.92) and specificity (.90) as well as demonstrating convergen…
Rorschach et maladies somatiques : Applications et éléments de validité
2004
Resume L'objet de cet article est d'offrir une revue des principales applications du Rorschach au domaine des maladies somatiques. Les etudes se rapportant a trois domaines sont presentees et critiquees (en allant du plus theorique ou plus empirique) : (1) La cotation des contenus par des echelles comme celle de Fisher et Cleveland (1958) ou de Masling, Rabie et Blondheim (1967) ; (2) Un ensemble d'etudes s'interessant a un “ facteur de risque ” psychosomatique (l'alexithymie) ; (3) Un groupe de recherches visant a evaluer les correlations des facteurs Rorschach avec les comportements de soin chez les personnes malades. Ces trois axes de recherche illustrent differentes logiques de relatio…
Construct Validity of Rizzo et al.'s (1970) Role Conflict and Ambiguity Scales: A Multisample Study
1998
La validite de construction des echelles de Rizzo, House, et Lirtzman (1970) a ete fortement critiquee ces dernieres annees. Les critiques portent sur la formulation des items qui constituent ces echelles, ce qui fait que l'interpretation des echelles depend totalement de la formulation des items. Ces critiques ont favorise l'emergence d'autres modeles factoriels. La duplication elargie de Kelloway et Barling (1990), l'analyse factorielle destinee a confirmer la validite des echelles de Rizzo et al. et une echelle de surcharge des roles avec des items formules a la fois affirmativement et negativement furent utilisees pour eprouver la validite de construction des echelles d'ambiguite et de …
Discriminant Validity of the Job-related Tension Scale
1993
L'Echelle de Tension Liee au Travail (JRTS) de Kahn et al. (1964) est l'une des echelles les plus usitees pour evaluer la tension professionnelle dans les etudes sur les correlats des conflits de roles et de l'ambiguite de role. Quelques auteurs ont suggere que cette echelle faisait appel aux concepts sous-jacents mesures par les echelles d'ambiguite et de conflits de roles (1970) de Rizzo, House, & Lirtzman (Jackson & Schuler, 1985). Dans cet article, la validite discriminante de la JRTS est mise factoriellement a l'epreuve
The structure of Antonovsky's Orientation to Life Questionnaire
1998
The present study investigated the structure of Antonovsky's (1987) short-form (13-item) Orientation to Life Questionnaire (OLQ). The OLQ was developed to measure sense of coherence, which consists of three interrelated components: meaningfulness, comprehensibility and manageability. Confirmatory factor analyses were carried out using data on three occupational groups (technical designers n = 989, teachers n = 1012, managers n = 1035). The factor analysis models were specified and compared in the study: (1) a first-order one-factor model; (2) a first-order correlated-three-factor model; and (3) a second-order model with three first-order factors. The results suggested that the first-order c…
A GIS-based approach for gully erosion susceptibility modelling: a test in Sicily, Italy
2013
The aim of this study is to analyze the susceptibility conditions to gully erosion phenomena in the Magazzolo River basin and to test a method that allows for driving the factors selection. The study area is one of the largest (225 km2) watershed of southern Sicily and it is mostly characterized by gentle slopes carved into clayey and evaporitic sediments, except for the northern sector where carbonatic rocks give rise to steep slopes. In order to obtain a quantitative evaluation of gully erosion susceptibility, statistical relationships between the spatial distributions of gullies affecting the area and a set of twelve environmental variables were analyzed. Stereoscopic analysis of aerial …
