Factor analysis of the French version of the 20-Item Toronto Alexithymia Scale (TAS-20).

A French version of the Toronto Alexithymia Scale-20 Items (TAS-20) was factor-analyzed on a sample of 263 university students and its factor solution analyzed along with the studies using the Canadian version. Our results show a two-factor solution where the items rating the difficulty to identify feelings and the items rating the difficulty to describe feelings constitute a sole factor contrary to the Canadian version. These data are reviewed in the context of previous research and offer two subscales for future investigations utilizing the TAS-20.

Spasmodic torticollis--review of 220 patients.

220 patients with isolated and idiopathic spasmodic torticollis were followed and treated over a 14 year period. Each patient was given a short questionnaire leading to the present retrospective data analysis. In most areas, including female preponderance and frequency of postural tremor, the findings confirmed previous studies and highlighted particular points: importance of psychopathological antecedents and association with stressful life-events. The discussion deals with some of the conflicting debates surrounding this unusual disorder. What is the role of psychopathological factors? What is the therapeutic prognosis? The best therapeutic results were obtained by combining anticholinergic drugs, local injections and rehabilitation.

[Lithium and cerebral functions].

Two cases, sustaining the possible part of long term lithium therapy in progressive intellectual deterioration, are submitted. Arguments clinic as well as paraclinical and fundamental, supporting the idea of insidious lithium's neurotoxicity are discussed. Most recent findings about drug's incidence on the cerebral functioning are reviewed. The study of the erythroplasmatic ratio and the analysis of several factors implied in its variations seem to back up our hypothesis.

[Factorial structure and internal consistency of the French version of the twenty-item Toronto Alexithymia Scale in a group of 183 healthy probands].

The factorial structure of the French version of the twenty-item Toronto Alexithymia Scale (TAS-20) was studied in a group of 183 healthy subjects. The TAS-20 represents the latest revised version of the TAS. His psychometric characteristics are clearly superior than the others alexithymia scales. Our subjects filled out the TAS whose 14 items are common with the TAS-20. We conducted our statistical analyses on these 14 items. A principal components analysis was carried out and yielded a two-factor solution where the items rating the ability to describe feelings and the items rating the ability to identify feelings constitute one sole factor. The second factor corresponds to the externally oriented factor. The internal consistency of the scale was also measured by the Cronbach alpha coefficient and by the correlation between each item and the total score. The value of the Cronbach alpha was 0.79 and the correlation between each item and the total score ranges from 0.19 (p < 0.05) to 0.69 (p < 0.001) with a mean of 0.52. Our results confirm a previous work on a group of 263 normal students which showed a two-factor solution of the TAS-20. The French version of the TAS-20 seems to be reliable and constitutes a useful instrument to study alexithymia in psychopathology.
