AbstractObjectives: To determine the prevalence of psychiatric disorders in adults with learning disabilities, and the relationship with severity of learning disabilities.
Method: The study is population-based. Detailed psychiatric assessments on 207 adults with learning disabilities living in Leicestershire, UK. were conducted by a learning disabilities psychiatrist, using the Present Psychiatric State - Learning Disabilities; and Disability Assessment Schedule. Diagnostic criteria are clearly defined. Developmental assessments were undertaken using the Vineland Scale (survey form).
Results: Psychiatric disorders were found in 49.2%, and rates for most individual disorders were higher than those found in the general population. Comparison with the two previous population-based studies shows the ascertained rates were broadly similar to those reported by Corbett but higher than those reported by Lund. Adults with more severe learning disabilities had higher rates of additional psychiatric disorders.
Conclusions: The results may be explained by a combination of the genetic, physical, psychological and social factors associated with learning disabilities also being aetiological to psychiatric disorders. The high prevalence rates of psychiatric disorders demonstrate the importance of health service provision for adults with learning disabilities.
摘要目的:确定有学习障碍的成年人中精神病的患病率,以及与学习障碍严重程度的关系:确定有学习障碍的成年人中精神病的患病率以及与学习障碍严重程度的关系:研究以人群为基础。由一名学习障碍精神科医生使用 "目前精神状态--学习障碍 "和 "残疾评估表 "对居住在英国莱斯特郡的 207 名学习障碍成人进行了详细的精神评估。诊断标准定义明确。使用文兰量表(调查表)进行了发育评估:结果:49.2%的患者患有精神障碍,大多数患者的精神障碍发病率高于普通人群。与之前两项基于人群的研究相比,发现的比率与 Corbett 的报告大致相似,但高于 Lund 的报告。有更严重学习障碍的成年人患其他精神疾病的比例更高:这些结果可以解释为与学习障碍相关的遗传、生理、心理和社会因素也是导致精神疾病的病因。精神病的高发病率表明,为有学习障碍的成年人提供医疗服务非常重要。
