To examine differences between samples of schizophrenia patients recruited from general practice and public mental health services.
Demographic, psychosocial, disability and 12-month service utilization data are reported from a multicentered survey of psychotic disorders and an associated study of schizophrenia in general practice. Patients with schizophrenia from three recruitment sources (in-patient, community services, general practice) were compared.
General practice patients had fewer symptoms, better functioning, lower service use, but comparable substance abuse, to patients from mental health services. They were generally similar to community mental health patients, with the exception of family support, premorbid work adjustment, negative symptoms and disability. Service contact models are also reported which demonstrate that general practitioners deal with schizophrenia patients across the range of illness severity and acuity.
Recruitment source impacts in schizophrenia research need to be more carefully considered during sample selection and better accounted for in the interpretation of results.
研究从普通诊所和公共心理健康服务机构招募的精神分裂症患者样本之间的差异。
报告了一项关于精神障碍的多中心调查以及一项普通诊所中精神分裂症相关研究的人口统计学、心理社会、残疾状况和12个月服务利用数据。比较了来自三个招募来源（住院患者、社区服务、普通诊所）的精神分裂症患者。
与心理健康服务机构的患者相比，普通诊所的患者症状较少、功能较好、服务使用较少，但药物滥用情况相当。除了家庭支持、病前工作适应、阴性症状和残疾外，他们与社区心理健康患者总体相似。还报告了服务接触模式，表明全科医生应对不同疾病严重程度和急症程度的精神分裂症患者。
在精神分裂症研究中，样本选择期间需要更仔细地考虑招募来源的影响，并在结果解释中更好地加以说明。
