This research explores the family configurations of young adults with intellectual disability. Based on a sample of 40 individuals interviewed two times in a year, we found as many as four types of family configurations, with distinct compositions, and different types of social capital. This diversity is not without consequences for individual psychological adjustment. The results are discussed in the light of the configurational approach to families. 相似文献

Background: Malformations of the cerebral cortex may be associated with severe epilepsy and status epilepticus. It has been shown that status epilepticus models induce excitotoxic cell death. In humans, very few data are available. Case and results: We report a case of a multifocal disorder of the lamination diagnosed in a neonate, borne at 30 weeks’ gestation, who died from a refractory status epilepticus at two months and half. This abnormality was not detected by repeated MRI studies. Only microscopic investigations permitted to identify this disorder of the lamination. We found also little cell death or cell loss. Discussion: Our report highlights the possible false negative results of MRI in a newborn. We can also discuss that immature human brain maybe less sensitive to neuronal injury than mature as described in animal models. 相似文献

Background: Despite the increasing popularity of video game playing, little is known about the similarities and differences between online and offline video game players. Objectives: The aims of this study were (i) to test the applicability and the measurement invariance of the previously developed Problematic Online Gaming Questionnaire (POGQ) in both online and offline gamers and to (ii) examine the differences in these groups. Methods: Video game use habits and POGQ were assessed in a sample of 1,964 (71% male) adolescent videogame players. Those gamers who played at least sometimes in an online context were considered “online gamers,” while those who played videogames exclusively offline were considered “offline gamers.” Results: Confirmatory factor analysis supported the measurement invariance across online and offline videogame players. According to the multiple indicators multiple causes (MIMIC) model, online gamers were more likely to score higher on overuse, interpersonal conflict, and social isolation subscales of the POGQ. Conclusion: The results of the present study suggest that online and offline gaming can be assessed using the same psychometric instrument. These findings open the possibility for future research studies concerning problematic video gaming to include participants who exclusively play online or offline games, or both. However, the study also identified important structural features about how online and offline gaming might contribute differently to problematic use. These results provide important information that could be utilized in parental education and the prevention program about the possible detrimental consequences of online vs. offline video gaming. 相似文献
