To determine the prevalence of psychiatric disorders in adults with learning disabilities, and the relationship with severity of learning disabilities.
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).
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.
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.
确定成年学习障碍者精神障碍的患病率，以及与学习障碍严重程度的关系。
该研究以人群为基础。由一名学习障碍精神科医生对居住在英国莱斯特郡的207名成年学习障碍者进行详细的精神评估，使用《当前精神状态 - 学习障碍》和《残疾评估量表》。诊断标准明确界定。使用文兰量表（调查表）进行发育评估。
发现49.2%的人患有精神障碍，大多数个体障碍的患病率高于普通人群。与之前两项基于人群的研究相比，确定的患病率与科比特报告的大致相似，但高于伦德报告的患病率。学习障碍更严重的成年人患有其他精神障碍的比例更高。
这些结果可能是由于与学习障碍相关的遗传、身体、心理和社会因素也导致了精神障碍。精神障碍的高患病率表明为成年学习障碍者提供医疗服务的重要性。
