The effects of attitude and subjective norm were investigated on physicians' intention to use seven drug information sources: the PDR, medical textbooks, medical journals/newsletters, pharmaceutical manufacturers' literature, pharmaceutical manufacturers' representatives, other physicians, and pharmacists. The effects of past behavior and practice characteristics were also examined.
An eight-page mail questionnaire queried health maintenance organization physicians on their intention to use, attitude (emotional response) and subjective norm (colleagues' approval/disapproval) toward use of each source when searching for drug information on a fictitious, new H2 antagonist agent.
Responses were received from 54% (108) of the 200 physicians surveyed. Positive attitudes toward use had the greatest influence upon intention to use each of the sources (b > or = .40) (except for pharmacists, for which subjective norm was the most important predictor (b = .31)). Past behavior directly affected intention to use the PDR (b = .27), and pharmaceutical manufacturers' literature (b = .26). The effects of attitude and/or subjective norm on intention to use non-commercial sources of drug information were moderated by the practice characteristics.
These findings suggest that physicians' use of drug information sources is strongly influenced by their attitudes toward use. In addition, the importance of situational contingencies should not be overlooked when investigating the use of drug information sources.
研究态度和主观规范对医生使用七种药物信息来源的意向的影响，这七种来源包括：《医师案头参考》（PDR）、医学教科书、医学期刊/时事通讯、制药商的宣传资料、制药商代表、其他医生以及药剂师。同时也考察了过去行为和执业特点的影响。
一份长达八页的邮寄调查问卷询问了健康维护组织的医生，关于他们在查找一种虚构的新型H2拮抗剂药物信息时使用每种信息来源的意向、态度（情感反应）和主观规范（同事的赞成/反对）。
在200名接受调查的医生中，有54%（108名）回复了问卷。对使用的积极态度对使用每种信息来源的意向影响最大（b≥0.40）（药剂师除外，对药剂师而言，主观规范是最重要的预测因素（b = 0.31））。过去的行为直接影响使用PDR（b = 0.27）和制药商宣传资料（b = 0.26）的意向。态度和/或主观规范对使用非商业性药物信息来源意向的影响受执业特点的调节。
这些研究结果表明，医生对药物信息来源的使用受到他们对使用的态度的强烈影响。此外，在调查药物信息来源的使用情况时，情境偶然性的重要性不应被忽视。
