The high cost of mental health surveys of the general population has sparked interest in less costly research methods. Two low-cost mental health survey strategies (mail and telephone) were compared in terms of cost, response rate and quality of data obtained. A total of 1,074 persons agreed to participate in the study as a sample, one-half by telephone and the other half by mail. They completed the Diagnostic Interview Schedule Self-Administered, a questionnaire designed to be self-administered, which was used to assess specific mental disorders and to evaluate risk factors. In addition, 239 respondents who were selected according to the presence or absence of specific diagnoses were reinterviewed face-to-face using the Diagnostic Interview Schedule as an external criterion. The telephone method yielded a better response rate (15% higher) and better control over answers (for example, less missing data). The mail strategy was less expensive and appeared to yield data of slightly better quality, particularly for respondents suffering from anxiety disorders.
对普通人群进行心理健康调查的高昂成本引发了人们对成本较低的研究方法的兴趣。研究人员比较了两种低成本心理健康调查策略（邮寄和电话）在成本、回复率和所获数据质量方面的差异。共有1074人同意作为样本参与研究，其中一半通过电话方式，另一半通过邮寄方式。他们完成了《诊断访谈表（自填式）》，这是一份设计为自填式的问卷，用于评估特定精神障碍和危险因素。此外，根据是否存在特定诊断挑选出239名受访者，以《诊断访谈表》作为外部标准进行面对面再次访谈。电话调查方法的回复率更高（高15%），对答案的控制更好（例如，缺失数据更少）。邮寄策略成本更低，似乎能产生质量稍好的数据，尤其是对于患有焦虑症的受访者。
