Aseptic meningitis, Montreal, 1969: a clinical and laboratory study.
During the summer and fall of 1969 an outbreak of aseptic meningitis occurred in Montreal and its environs. Forty-four patients were admitted to the infectious disease ward of The Montreal Children's Hospital in August, September and October. Half of the patients were in the age group 6 to 10 years. The ratio of males to females was two to one. Patients showed the typical signs and symptoms of aseptic meningitis, namely fever, vomiting, headache, neck stiffness and pleocytosis of the cerebrospinal fluid.Viruses were recovered from 19 (43%) of the 44 cases. The predominant virus in the outbreak was a non-hemagglutinating strain of echovirus 6. Other virus types isolated in the outbreak were echovirus 7, coxsackievirus A9 and coxsackievirus B4. Serological investigations confirmed the validity of the echovirus isolations and identified additional cases.

[French version of TASTE (test for the ability and evaluation)].
Ability to study and evaluation is only one example of performance among many others but research and publications concerning this issue for more than 50 years, especially in the context of test anxiety and need of achievement, conferred upon it a prototypical dimension. Investigations about motivation also stimulate many scientists and constitute another foundation of this study (13). The level of performance depends on knowledge and motivation (33). Time devoted to study is essential to succeed; so motivation and procrastination are in competition. The importance of reinforcement (extrinsical motivation) and the desire for learning and knowing (intrinsical motivation) are determinant. Other elements must be emphasized: guarantee of obtaining rewards, self efficacy and causal attribution. These considerations point out the multidimensional and interactive aspects of test anxiety (7, 31). The number of components is not described unanimously but experts agree with emotional, cognitive and behavioral dimensions (25). So, anxiety was approached in its motivational properties, and it was the case until the sixties, in terms of drive corresponding to a need like thirst or hunger (18); then it was conceptualized in a dynamic context broader than that of stress and coping (29, 30). Last, it constitutes the object of theories highlighting cognitive interference (9, 23, 26) or defective skills (8, 32). A lot of questionnaires were built without answering the different aspects and for instance without linking the theoretical and therapeutic components concerning this problem. Committed to the traditional fields of research (test anxiety and need of achievement), to Weiner's work about attribution theory (34) and that of Bandura in self efficacy (4, 5), E. Depreeuw (10) was particularly interested in Heckhausen's model (16, 17), trying to associate experimental conceptions with the clinical reality. On this basis, he elaborated the TASTE (10, 12, 20): test for ability to study and evaluation. At first constituted of 121 items, the self-questionnaire, after factorial analysis, was reduced to 78 items assessing 4 factors which represent the 8 components of Heckhausen's model (16). The first factor (30 items) concerns anxiety in its emotional and cognitive characteristics. Interesting data were observed by Depreeuw and confirmed in the Netherlands and in Greece (19), especially the fact that anxiety of girls is higher than that of boys when they are confronted with an exam. The second one (19 items) represents self-confidence: confidence in ability to succeed and on using adequate strategies. The third factor (14 items) squared with value attributed to performance. It especially comments on the intrinsical component of motivation. The fourth factor (15 items) corresponds to procrastination; study is postponed on behalf of activities which actually reduce the achievement process. The self-report questionnaire (where answers run from total disagreement to total agreement whether they correspond to the way of thinking or acting) takes account of the emotional, cognitive and behavioral dimensions of the model. The multidimensional aspect of this questionnaire, but mainly its connections with theory and clinic, are convincing; we adopted it with other tests in research about fear of failure. Validation of the French translation is the subject of this article. In order to realize this operation, we chose the initial version of TASTE (121 items) to assess a Belgian sample of french-speaking students in the first year of University of Liège (n = 617). They are differentiated by gender, faculty (Economy, Medicine, Philosophy, Psychology, Applied Sciences) and experience of failure, i.e. the fact of repeating a school year. Statistics were realized with SPSS and SAS. A comprehension test and a back translation are satisfactory. The stability over time too: the one week test-retest was achieved with a sample of 33 student nurses; comparing the factors two by two, intra-class correlations ranged from 0.5 to 0.95. The component analysis with Varimax rotation does not allow us to find the four factors of construction. We obtain the same disappointing results with the version of 78 items. According to the screentest, we adopted the solution of five factors which confirms the original construction. A fifth particularly strong factor (Cronbach's alpha 0.82) corresponds to devalorisation. The internal reliability is very satisfactory. If we consider the items strong loading (more than 0.30), the French version is constituted of 94 items. If we consider the items which are specifically loading each factor, we can reduce the questionnaire to 50 items. Internal reliability remains the same. Correlations between the data obtained with this brief version are satisfactory; comparing the factors in pairs. Pearson's coefficients range from 0.8 to 0.89. The study of E. Depreeuw was realized ten years ago with a Belgian sample of Flemish-speaking students; is the cultural context or an evolution in test anxiety which explains such a difference in the results? We are now assessing a sample in another country which used the TASTE in 1996 in order to have some information about comparison of samples. In any case, the questionnaire of E. Depreeuw respects the multidimensional aspect of test anxiety. Our choice of 5 factors according to principal components confirms the original structure of the test but also discriminates another factor which could be predictive of psychopathology (panic, depression). This new dimension measures negative perception of ability and achievement especially when compared with other students. One aim of such a study is to discern clusters of students i.e. groups of students with characteristics such as Covington (7), Depreeuw (20) and Zeidner (35) describe them. This description is very important; the French version is only a part of a very broader study including other tests and could differentiate student's profiles. The French version of 5 factors finally gives results in agreement with the original. The items (10 per factor) are selected according to their highest specificity and after elimination of redundancy. Validity remains in the short version, making it more useful in clinical practice.
[Failure effects and gender differences in perfectionism].
Perfectionism is a dimension which has been studied very little as a separate entity. It is not even considered as a nosological factor. No classification of the medical sciences underlines its importance other than to speak of a personality trait, of an aspect, or of a parameter. Nevertheless, perfectionism is related to multiple disorders such as depression (18, 20, 36), suicide (8, 16, 55), nutritional problems (11, 28), anxiety (3), obsessive-compulsive personality disorder (53), social phobia (2), as well as insomnia (46). Certain authors stress the possible role of perfectionism in the development or the persistence of a substantial number of these disorders (7, 22, 38). Given these facts, it is all the easier to understand the interest shown by clinicians and researchers in the subject. Better detection and evaluation of its impact on behaviour is important in putting therapies in place (6, 53). Relationships between perfectionism and fear of failure have been approached (21, 51, 54). Correlations between perfectionism and high levels of state and trait anxiety have been demonstrated (23). The evaluation of perfectionism has been dealt with very little. Some questionnaires devote a sub-category to it, such as the Eating Disorder Inventory and the Irrational Beliefs Test. However, recently, it has been recognized that perfectionism is a multidimensional construct. Two Multidimensional Perfectionism Scales have been developed and investigated in relative isolation. Frost, Marten, Lahart and Rosenblate defined perfectionism as the setting of excessively high standards for performance associated with critical self-evaluation. Six dimensions are described: concern over making mistakes, high personal standards, parental expectations, parental criticism, doubt about quality of performance and organization. Internal consistency and validity have been established (25, 26). Hewitt and Flett (30, 31, 33, 35) have developed another approach where three dimensions of perfectionism are described: SOP (Self Oriented Perfectionism) related to high standards and self criticism, SPP (Socially Prescribed Perfectionism) related to the need of approval from others and fear of negative evaluation, OOP (Other-Oriented Perfectionism) reflecting a tendency to set high expectations for others and to evaluate them in a demanding way; this component is related, especially for males, to self-esteem, hostility and authoritarianism. Validity and internal consistency have been established too (30, 31, 35). The Frost and al's Multidimensional Perfectionism Scale and the Hewitt and Flett's scales are closely associated, except concerning the OOP. Because this component could provide new information, we have chosen the second scale, referring to the French translation and validation of Labrecque (45). EMP is the French name of MPS; it is a self-report questionnaire of 45 questions, in fact three subscales of 15 items rated on a 7-point Likert-type scale. MPS was administered to 617 first year students at the university of Liège (table II). Differences are considered according to gender and experience of failure i.e. the fact of repeating an academic year. We realized a component analysis with promax rotation. Among the different possibilities offered by the scree-test the choice of a 4 factor solution stresses the original structure: SOP (14 items), SPP (12 items), OOP (9 items) and anti OOP (10 items); the last one is additional but allows for respecting semantics and saturation of the items. The first aim of confirming validity and internal consistency is satisfactory. In other respects the multidimensional structure of the concept leads to consideration of a positive, adaptive perfectionism and a more negative perfectionism, facilitating psychopathology (59, 60, 61). So it seems interesting to compare the different components of MPS in order to find an eventual sex-failure effect. The evaluation of perfectionism is obvious, considering it as a personality trait, but it can be used also in taking into account stress and its impact, for instance that of academic performance (29, 37, 39, 58). Conferring on MPS more pertinence in gender differentiation and failure evaluation is an other goal of this research. Through the particular choice of statistical results, sex and sex-failure effects can be demonstrated: a MANOVA underlines sex effect (lambda de Wilks = 0.96, p = 0.001) and sex-failure effect (lambda de Wilks = 0.98, p = 0.05). Structure of MPS is different in four groups (FE: women with failure, FnE: women without failure, ME: men with failure, MnE: men without failure). ANOVA show differences of MPS3, MPS1 and MPS2. Far more promising is the use of LISREL method allowing for the construction of a coherent model of relationships between some dimensions of MPS and Test-Anxiety, approached here with THEE (test d'habileté aux études et à leur évaluation) French abbreviated version (49) of TASTE (Test for Ability to Study and Evaluation). In fact according to the literature of fear of failure, girls score higher on anxiety and procrastination but less on self-confidence. The structural model shows different pathways, more especially between SPP (socially prescribed perfectionism), T2 (sense of incompetence) and T1 (anxiety). SOP (self oriented perfectionism) and SPP (socially prescribed perfectionism) by girls are very much correlated; it seems that they are more subjected to society and its exigencies of studying but consequently they are more at risk of anxiety and a sense of incompetence. SOP (self oriented perfectionism) by boys functions more indiscriminately of SPP (socially prescribed perfectionism) and is negatively correlated with self-incompetence; boys are more self-confident but they usually procrastinate more probably because failure expectancies would be particularly harmful for their self-esteem; consequently, failure should be related to something else than their own capacity; this may be an explanation of the high rate of male dropouts and failure in the first year at the university of Liège; also a factor explaining the female domination at the university. In the same way the first choice of studies is moving towards shorter and less difficult orientation (46). In case of failure the model is very similar according to gender: SOP (self oriented perfectionism) and T1 (anxiety) are directly connected; SOP and SPP are in this case better correlated by boys but the path between SPP, sense of incompetence and anxiety is less significant than in girls. In conclusion, providing some modifications according to semantics, the choice of a four factor solution allows for confirmation of the original structure of MPS and for internal consistency. The different components of MPS vary according to gender: SOP and more OOP discriminate men and women; SPP allows for differentiating women with failure. A structural model enhances the role of perfectionism in the cognitive and behavioural contexts; for instance it clarifies its action on fear of failure and success rates according to gender.
