The 20-item Toronto Alexithymia Scale was developed in previous research to measure a general dimension of alexithymia with three intercorrelated factors. These three factors reflect distinct facets of the alexithymia construct: ( I ) dificulty identifving feelings and distinguishing them from the bodily sensations of emotion, (2) dificulty describing feelings to others, and ( 3 ) an externally orientated style of thinking. This study tested the three-factor model for the TAS-20, using confirmatory factor analysis, in separate samples of young adults from Germany, Canada, and the United States. The previously established three-factor model was found to be replicable in all three samples. In addition, the full TAS-20 and its three factors demonstrated adequate internal reliability in all three samples. Although evaluation of the convergent, discriminant, and criterion validity of the TAS-20 is required in diverse cultural groups, the present results provide evidence for the factorial validity and internal reliability of the TAS-20.Requests for reprints should be sent to James

This article investigates the relationship between culture, personality, and deception in a simulated international management negotiation at multiple levels of analysis. `Deception' was operationalized here as the propensity to lie and bribe. As predicted, at the cultural level the results from a scenario study with 1583 participants from eight cultures suggested that cultural collectivism was positively related to reported use of deception in negotiations, and to greater emotional reactions (i.e. guilt, shame, and disgust) after the use of deception. At the individual level, however, the personality variable of allocentrism (consisting of behaviors found in collectivist cultures) was negatively related to the use of deception. Theoretical implications are discussed.

Abnormalities in lipid metabolism frequently accompany renal disease and may be important in the pathogenesis of progressive renal injury. In the present study, the effects of a high cholesterol diet on renal histology, cortical lipids, and glomerular hemodynamic function were examined in normal rats with and without reduced renal mass. Cholesterol feeding for 19 weeks increased serum cholesterol from 66 +/- 10 mg/dl to 256 +/- 93 mg/dl in two-kidney rats, and from 73 +/- 15 mg/dl to 407 +/- 274 mg/dl in nephrectomy rats (P less than 0.01). Both sham-operated and unilateral nephrectomy rats fed a high cholesterol diet had a greater amount of glomerulosclerosis and tubulointerstitial damage than rats fed standard chow. Cortical cholesteryl esters were increased by the cholesterol diet, and correlated with the amount of glomerulosclerosis (r = 0.90, P less than 0.01) and tubulointerstitial injury (r = 0.64, P less than 0.05). Cholesterol feeding and nephrectomy both caused alterations in tissue essential fatty acids, and a panel of specific monoclonal antibodies indicated that renal injury and cortical lipid alterations were associated with an increase in glomerular macrophages. Finally, micropuncture experiments carried out in a separate group of rats fed high cholesterol for 8 to 10 weeks demonstrated increases in glomerular capillary pressure. These results suggest that additional investigations may ultimately determine how cholesterol deposition, altered fatty acid metabolism, macrophages, and increased glomerular pressure might combine to cause chronic progressive renal injury.

The purpose of this study was to describe the relative strengths of a number of variables on burnout among psychiatric nurses. A meta-analysis of correlations revealed that burnout was negatively associated with job satisfaction, staff support and involvement with the organization and positively associated with role conflict. The results of the meta-analysis were in line with results of other studies in which different populations were investigated. Therefore, the findings as such are not specific to psychiatric nurses. Based on the literature, three typical risk factors of burnout among psychiatric nurses were found: the patient group the nurse works with, such as patients who are aggressive and suicidal; the inequity in the exchange process between nurses and patients; and the unrealistic expectations of nurses of the patients' potential for rehabilitation.
