[Validation of the French translation of the impulsive nonconformity scale]. / Traduction et validation de la version française de l'échelle d'impulsivité non conformité de Chapman.

INTRODUCTION: Impulsive traits are key characteristics in a lot of psychiatric disorders and are part of the "normal" behaviour spectrum. Although impulsivity is a controversial concept, some questionnaires have focused on its "dysfunctional" aspect. The Barratt Impulsive Scale (BIS-10) is the scale the most used to explore impulsiveness, but it does not explore antisocial or nonconform behaviour. The Chapman Impulsive and Nonconformity Scale (INCS) is a questionnaire of 51 items that measures the impulsivity and nonconformism. The INCS reflects "failure to internalize societal norms, lack of empathy for the pain of others, and an unrestrained yielding to impulse and self-gratification" and was originally designed to assess psychosis proneness. It has been validated in the USA, but has not yet been validated in France. Interestingly, although it was not predictive of psychosis, high scorers on INCS exceeded controls on depression, and on rates of substance abuse. Furthermore, participants scoring high on hypomanic personality scale and INCS were found to have an especially heightened risk for bipolar disorders. OBJECTIVE: To translate and determine reliability and validity of the French version of the Chapman Impulsive and Nonconformity Scale in young adults by comparison with the BIS. METHOD: Chapman Impulsive and Nonconformity Scale has been back-translated into French, and filled out by 237 students (males: 104; females: 133; mean age: 20.4 [range 19-25]). BIS-10 was used for convergent validity. Each participant completed the two scales. Reliability and validity of the French form of INCS were assessed with the internal consistency (coefficient alpha of Cronbach and the split half reliability) and the convergent validity. RESULTS: In the French version of the INCS, the 51 items have high internal reliability (Cronbach's alpha=0.81 and split half reliability=0.80). Concerning the BIS, internal reliability is good (Cronbach's alpha=0.72 and split half reliability=0.66). Moreover, Pearson's r of the INCS/BIS is statistically significant (0.65) and underlines the concomitant validity of the INCS with the BIS. CONCLUSION: The psychometric properties of the French version of the INCS are very similar to those of the English version. Hence, the INCS could provide a way to explore the two related dimensions: impulsivity and nonconformism.

Emergency hospitalization in the elderly in a French university hospital: medical and social conditions and crisis factors precipitating admissions and outcome at discharge.

Emergency admissions of elderly patients constitute a major management issue due to the complexity of their problems. The aim of this retrospective observational study was to identify medical and social characteristics and crisis factors for emergency department (ED) hospitalization in elderly patients, and to evaluate the influence of these factors on the length of stay and outcome at discharge. During a 4-month period, 396 patients aged 70 years and older were referred to the ED of a University Hospital (Hjpital Edouard Herriot) in Lyon, France. A questionnaire specifically designed for the study was completed for each patient using the information in the patients' files previously filled in by the "Rapid Geriatric Assessment Team" of the ED. We described civil and marital status, living conditions, reason for admission to ED and other associated pathologies according to the ICM-9, crisis factors, length of stay (LOS) and outcome at discharge. The mean age was 81.9 years (SD 6.5); two thirds (66.7%) of the study subjects were female, and 46.7% were widowed; the majority (68.7%) lived in their own homes. The main reasons for admission were cardiopulmonary diseases in 31.6% of cases, followed by neuropsychiatric disorders in 28.2%, and falls in 8.3%; a final category (31.8%) included subjects admitted for general, non-specific symptoms. Among the crisis factors observed, 49.4% presented an acute episode of a chronic illness, 33.6% lived alone, and 20.9% had been hospitalized during the 6-month period preceding the study. The average LOS was 3.15 days. The multivariate model showed that falls increase LOS by 74%, dementia by 65%, and depression by 21%. Upon discharge, 13% returned to their residence before hospitalization, 55% were transferred to a medical speciality ward, and 4% to other facilities, whereas only 19% were transferred to a geriatric ward, and 9% died during their stay in the ED. The multinomial model showed that outcome at discharge was influenced by functional dependency, dementia, depression, and acute episodes of a chronic illness. For many elderly, the ED remains a critical point of access to more complete managed care. This elderly population is comprised of polypathological, frail persons whose morbid state requires multidisciplinary management in geriatric units. The findings of this study suggest that interventions of multidisciplinary networks, such as home health care programs aimed at detecting crisis factors and establishing early prevention of crisis states, may improve unfavorable medical and social conditions and reduce hospitalization in geriatric patients.
