[How educating students in depression among older people can affect their motivation to work with this population]. / La formation en gérontopsychiatrie sur la dépression chez les étudiants de licence de deuxième année en psychologie (université de Clermont-Ferrand) : impact sur leur motivation à travailler auprès de personnes âgées.

INTRODUCTION: Negative representations of ageing are conveyed in our society. We see that people frequently avoid working with older people, due to a lack of motivation. Depressive signs in older people are more frequently associated with normal ageing, rather than a pathology, giving health professionals the feeling that therapeutic efforts are likely to be unproductive. Yet, depression is a major public health problem, particularly among older people. It is a real pathology, affecting 20% of people aged 65 and older. In retirement homes the percentage can be as high as 45%. OBJECTIVE: To study and evaluate how theoretical knowledge about older people and depression affects the motivation of 2nd year psychology students to work with this population. METHODS: The study involves two groups. One of the groups (experimental group) followed an 8hour course on depression in older people, whereas the other (control group) followed an 8hour course on a different topic. The study was conducted in two parts. First, the two groups answered an initial questionnaire which measured how motivated they were to work with older people and what they knew about depression in older people. Then, after the experimental phase, all of the students answered the same questionnaire a second time. RESULTS: The comparison shows a significant decline in knowledge between T1 and T2 for the control group (P<0.05), and a significant increase in the number of correct answers for the experimental group (P<0.001). Statistical results show that after receiving education in depression, students are more motivated to work with older people. Moreover, we observe that the more knowledge students have in this field, the more motivated they will be to work with older people. DISCUSSION: Whereas there were no differences in knowledge before the course, we observed that the knowledge of the group who took part in the course about older people improved. Also, the evaluation showed that students who took the course were significantly more knowledgeable. Regarding motivation, our results vary according to the type of motivation. Overall, as regards intrinsic motivation, we observed an increase in motivation, insofar as the students who had followed the course were subsequently more likely to work with older people. Taking part in the course led to a systematic increase in the evaluation of extrinsic motivation. With respect to knowledge, half of the students interviewed think sadness or depression is a natural part of ageing. So, we observe that future health professionals often regard the signs observed in this population, such as sadness, apathy, and depression, as part of normal ageing. The people working with older people do not make the connection to actions and consequently in this action to wrongly thinking they are not in control of the situation. Depression is widely underestimated. Forty percent of cases of depression among older people go undetected. This study highlights the importance of making health professionals and future health professionals more aware of depression among older people. Knowing more about depression in this population can help guide recourse to psychology in gerontology.

Fox baiting against Echinococcus multilocularis: contrasted achievements among two medium size cities.

In Europe, most cities are currently colonized by red foxes (Vulpes vulpes), which are considered to be the main definitive host of the zoonotic cestode Echinococcus multilocularis. The risk of transmission to humans is of particular concern where high fox populations overlap with high human populations. The distribution of baits containing praziquantel has successfully reduced the infection pressure in rural areas and in small plots within large cities. The purpose of this study was to assess its efficiency in two medium size cities (less than 100,000 inhabitants) in areas of high human alveolar echinococcosis incidence. From August 2006 to March 2009, 14 baiting campaigns of praziquantel treatment were run in Annemasse and Pontarlier (Eastern France), each of which encompassed 33 km(2), with a density of 40 baits/km(2). The bait consumption appeared to be lower in strictly urban context compared to suburban areas (78.9% vs. 93.4%) and lower in Annemasse than in Pontarlier (82.2% vs. 89.5%). During our study, the prevalence of E. multilocularis, as assessed by EM-ELISA on fox faeces collected in the field in Annemasse, was lower within the treated area than in the rural control area. A "before/during" treatment comparison revealed a significant decrease of spring prevalence from 13.3% to 2.2%. No significant change in prevalence was detected in Pontarlier (stable prevalence: 9.1%) where the contamination of the treated area followed the temporal trend observed in the control area. There, a greater resilience of the parasite's life cycle, probably due to a strong pressure of recontamination from outside the treated area, may have counteracted the prophylaxis treatment. These contrasted outcomes suggest that the frequency of fox anthelmintic treatment should be adapted to the local situation.
