Better methods of assessing patients' and family members' causal models of illness are needed to improve adherence with biomedical interventions and to design services that meet the needs of consumers.
To develop a quantitative measure suitable for assessing the relationship of causal beliefs to expressed emotion, stigma, care-seeking and adherence.
The Causal Models Questionnaire for Schizophrenia, which includes 45 causes identified during in-depth interviews with family members, was administered to 245 family members of 135 patients with DSM-III-R schizophrenia in Suzhou and Siping, China at the time of admission to hospital.
Respondents, who identified a mean of 2.5 causes (range 1-10, mode 2), attributed 84% of the cause of schizophrenia to social, interpersonal and psychological problems. Hence, their beliefs do not concur with Chinese professionals' ideas about the biomedical causes of schizophrenia. Multivariate analyses identified the socio-economic factors that influence family members' causal beliefs.
Despite the complexity of causal models, measures can be developed that will help improve clinicians' communication with patients and understanding of help-seeking behaviours.
需要更好的方法来评估患者及其家庭成员对疾病的因果模型，以提高对生物医学干预措施的依从性，并设计出满足消费者需求的服务。
开发一种定量测量方法，适用于评估因果信念与表达性情绪、耻辱感、寻求治疗行为和依从性之间的关系。
对中国苏州和四平的135例符合DSM-III-R精神分裂症诊断标准患者的245名家庭成员进行了《精神分裂症因果模型问卷》的调查，该问卷包含在对家庭成员进行深入访谈时确定的45个病因。
受访者平均指出2.5个病因（范围为1 - 10个，众数为2个），将84%的精神分裂症病因归因于社会、人际和心理问题。因此，他们的信念与中国专业人员对精神分裂症生物医学病因的看法不一致。多变量分析确定了影响家庭成员因果信念的社会经济因素。
尽管因果模型很复杂，但仍可开发出有助于改善临床医生与患者沟通以及对寻求治疗行为理解的测量方法。
