[Study of Beck's hopelessness scale. Validation and factor analysis].

The validation study and factorial analysis of the Beck's hopelessness scale is presented. Two groups were compared including patients suffering from depression (n = 100) and a control group (n = 93). Age and sex were comparable in the two groups. The hopelessness scale is valid, and differentiates depressive patients from control subjects. The scale has a good reliability (test-retest, r = .81) and a good internal consistency (alpha = .97) for depressive subjects and alpha = .79 for control subjects). It also shows a good concurrent validity with other scales assessing depressive cognitions, the automatic thoughts questionnaire, the dysfunctional attitudes scale (form A) and a scale assessing the suicidal risk (ERSD). No concurrent validity is found with scales assessing the intensity of depression, the Beck depression inventory and the Hamilton scale. The factorial analysis elicits a general factor, accounting for 38.15% of the variance, and reflecting negative feelings about the future. The study of all the factorial analysis shows the stability of the factorial structure.

[Preliminary validation of the French translation of anxiety sensibility index-revised (ASI-R)].

Anxiety sensitivity represents a stimulus-outcome expectancy that reflects individual differences in the propensity to experience fear in response to one's arousal-related bodily sensations. It refers to the fear of anxiety-related symptoms that are based on beliefs that such sensations have negative somatic, social or psychological consequences. Anxiety sensitivity occupies an important place in theory and research on panic and related interoceptive fear disorders. Findings from this body of research indicate that this construct may act as a specific vulnerability variable in the development of panic attacks and anxiety symptoms. However, anxiety sensitivity theory also has been applied to understanding mood disorders and chronic pain disorders. Thus, as a psychological construct, anxiety sensitivity holds specific relevance to understanding panic disorders and general relevance for expanding knowledge about negative emotional functioning in other pathologies. All the research on anxiety sensitivity has been completed with the 16-item Anxiety Sensitivity Index (ASI). The review of the literature using this instrument suggested that anxiety sensitivity has three lower-order factors that all load on a single higher-order factor. The lower-order factors represent Physical-Concerns, Mental Incapacitation Concerns, and Social Concerns, and the higher-order factor represents the global anxiety sensitivity construct (21). Taylor and Cox (22) suggested that this questionnaire was not designed on an a priori basis to measure the identified lower-order factors. The low number of items for the Social and Mental Incapacitation dimensions of the 16-item ASI often leads to relatively lower levels of reliability compared to the third dimension. To address this issue, Taylor and Cox (22) developed an expanded measure of the anxiety sensitivity construct. The 36-item Revised Anxiety Sensitivity Index (ASI-R) maintains the same format as the 16-item ASI, but expands the number of content domains assessed. The ASI-R was designed to assess 6 lower-order domains identified in previous factor analytic research using the 16-item ASI (21), including fear of cardiovascular symptoms, fear of respiratory symptoms, fear of gastrointestinal symptoms, fear of publicity observable reactions, fear of dissociative and neurological symptoms, and fear of cognitive dyscontrol. The principal components factor analysis using the ASI-R among psychiatric outpatients indicated that there were 4 lower-order factors tapping the constructs of (1) fear of respiratory symptoms, (2) fear of publicly observable anxiety reactions, (3) fear of cardiovascular symptoms, and (4) fear of cognitive dyscontrol (22). A recent study (27) provided an initial psychometric evaluation of the ASI-R in a large, diverse sample of people (n = 2,786) from 6 different countries: Canada, United States, Mexico, Spain, The Netherlands and France. The data suggested that the two-factor solution is most replicable than other solutions (2 to 6 factors). The underlying structure of the anxiety sensitivity construct was generally similar across countries, tapping fear about the negative consequences of anxiety-related physical and social-cognitive sensations. Lower-order factors were moderately to strongly correlated with one another and showed good internal consistency. This manuscript presents the French translation of the ASI-R and a preliminary validation study. This research was realized conjointly with the transcultural study previously mentioned (27). Seven hundred and one French university students (non-clinical participants) completed the questionnaire at the beginning of a class. Subjects were undergraduate students from 2 universities (psychology and classics). Table I provides age, sex and marital status. There were no differences between the two groups on sex. The two groups were not comparable on age and marital status. The psychology group was older than the other was. The psychology students were also more married. The total group (n = 701) comprises 79 men and 622 women, with a mean age of 21.29 (4.85). Table II provides the normative means and standard deviations for both groups of students. There was no difference between the two groups on the total of the questionnaire (no significant interaction between group and age). In regard to the physical concerns subscale and the social-cognitive concerns subscale, there was also no significant interaction between group and age. Assessment of the internal consistency of the ASI-R yielded an overall Cronbach alpha of 0.91 for the entire questionnaire, with an alpha of 0.88 for the fear of anxiety-related physical sensations subscale and 0.83 for the fear of anxiety-related social-cognitive sensations subscale. A series of ANOVAs between male and female groups revealed significant gender differences. As shown in table IV, women had significantly higher total score than did men. They also had significantly higher physical factor and social-cognitive factor scores than did men. This finding is consistent with research that indicates that women generally report more intense fears and men less intense fears, and that they differ in levels of overall anxiety sensitivity specifically (29). This preliminary report was the first attempt to examine the construct of anxiety sensitivity using the ASI-R in a French university students. It can serve as a reference point for future research.

[Validation and factor analysis of a phobia scale. The French version of the Marks-Mathews fear questionnaire].

The fear questionnaire (Marks and Mathews) is presented in an original french translation. The questionnaire's validity, sensibility and reliability are studied in four groups: agoraphobia with panic attacks, obsession-compulsion, social phobia and control. The scale has a good empirical validity especially for agoraphobia measurement. However in our study the boundaries between obsession compulsion and social phobia appear questionable. Principal components analysis yields four factors similar to those found by Marks and Mathews: agoraphobia, blood and injury phobia, social phobia, and anxiety-depression (including one panic item).

[Heterogeneity of the depressive mood. Construction of a polydimensional scale].

The evaluation of depressive mood implies several levels of the clinician's inferences: behaviour observation, subjective experience report, affective communication... The authors report the first stages in the construction of a specific depressive mood scale administered to a major depressive disorder population of 52 patients meeting DSM III criteria. The principal component analysis splits mood into three main factors: dysphoria, expressed sadness, emotional blunting. These various emotional dimensions should be taken into account for the analysis of drugs effects.

[Group memory therapy in neurologic amnesia].

The aim of our approach was to improve the memory of head injured memory impaired people without associated intellectual deterioration. Subjects participated in group each weekday during ten weeks. The aim of strategies was to help the patient of recovery learning strategies. Exercises can be repeated to produce the use of learning strategies in the real life. 19 patients (11 subjects with a traumatic brain injury and 8 subjects with a cerebral vascular accident) completed the treatment are measured before and after the rehabilitation. In a clinic study our memory therapy was more satisfactory on visual memory than verbal memory on a French standardised memory test (the Signoret memory battery). But there is no change in the evaluation of everyday memory measured with the AMQ of Van Der Linden. The comparison of the two sub groups has given to show which pathology will benefit the more the method. These first findings suggested that it was useful to reinforce everyday memory and to include the family members more. It will also be interesting to modify the program for the reeducation of the verbal memory. A control study was necessary to evaluate the validity of our approach.

[Obsessive-compulsive disorder in the child and adolescent: developmental aspects and therapeutic strategies].

The obsessive-compulsive disorder has only recently been recognized as a specific pathological entity in children, despite the fact that the first descriptions of pediatric manifestations date back to the beginning of this century (P. Janet, 1903) with further reports having been published regularly since that time. The first assessment of the complete epidemiologic, clinical and functional repercussions of the obsessive-compulsive disorder was reported by the Pediatric Psychiatric Group of the NIMH (Pr Judith Rapoport); of their various publications, one is well known in France: The Child who Couldn't Stop Washing (17). Among possible reasons for this delayed recognition are the special conditions for diagnosis and the frequent underestimation of its importance by the family, and sometimes by doctors. This underassessment could be due to confusion between the normal developmental rituals which are frequently seen between the ages of 3 and 5 years, and which do not cause any particular handicaps, and a more severe symptomatology which interferes with normal academic and social adaptation, presenting a substantially worse long-term prognosis. Having recognized the disorder, questions have arisen as to its possible linkage with the form seen in adults. There are numerous convergent argument suggesting a certain long-term persistence of this disorder throughout development and later life: 1) the relative stability of the incidence and prevalence of the disorder; 2) phenomenologic and developmental similarities; 3) most recently, comparable efficacy of treatments for pediatric and adult obsessive-compulsive disorder, whether by the behavioral modification approaches or by pharmacologic treatment, notably with the serotonin re-uptake inhibitors (clomipramine, fluoxetine, fluvoxamine).(ABSTRACT TRUNCATED AT 250 WORDS)

[Preliminary study of a list of obsessional thoughts. Validation and factorial analysis].

The validation study and factorial analysis of a list of obsessive thoughts is presented. Four groups were compared. They included patients suffering from obsessive compulsive disorders (n = 22), depression (n = 21), phobias (n = 16) and a control group (n = 21). The four groups were comparable as far as age, sex, and educational level were concerned. The list of obsessive thoughts is valid, reliable, and has a good internal consistency. The factorial analysis showed a first factor (accounting for 37.22% of the variance) reflecting perfectionism, and a second factor (accounting for 12.10% of the variance) reflecting a pathological sense of responsibility.

[Comparative study of normal subjects and obsessive compulsive subjects on intrusive thoughts and memory].

Four surveys have shown that more than 80% of normal subjects have obsessive thoughts with content similar to those found in obsessive compulsive patients. "Abnormal" and "normal" intrusive thoughts do not differ in content but in duration, frequency and rejectability. Thirteen DSM III-R non-depressed obsessive compulsive patients with checking rituals were compared with 13 sex-, age-, and education matched control subjects. Our study compared the content of abnormal and normal obsessions. No between-group difference was found suggesting that a sub-group of obsessive compulsive patients with checking rituals did not change the general result. The memory processes were also compared. Several investigators have shown an impairment in visual spatial memory tasks but none in verbal tasks with obsessive compulsive patients. In three studies non clinical checkers were found to show some deficits in memory compared to non checkers. In our study we used the Wechsler memory scale. Clinical checkers appear to have difficulties recalling details of meaningfully linked verbal sequence and immediate visual reproduction.

[Cognitive behavior therapy of agoraphobia, retrospective study of 345 cases].

Epidemiological data of 533 (42% male) agoraphobic patients referred to an anxiety disorder unit are reported. Comorbidity with mood disorders was high (48%). Therapeutic response was studied in 345 patients who received cognitive-behaviour therapy (CBT): 131 patients dropped out and 214 completed treatment. At post-test 71% of the completers were improved with maintenance of the gains in patients reevaluated at follow-up points ranging from 6 months to 18 years. Medication intake was significantly decreased. Intent to treat analysis of the whole CBT sample showed that 57% of the 345 patients were improved. Drop-outs were predicted by female sex and psychotic personality traits. This suggests that personality assessment should be carried out in agoraphobia and therapeutic interventions on personality considered in patients with disordered personality. The relatively low prevalence of women in the whole sample and their higher prevalence in drop-outs are discussed.
