An Evaluation of the Expectancy Value Model of Attitude Measurement for Physician Prescribing Behavior

Abstract

Presented are findings from research using expectancy value and normative belief measures to predict physician drug brand preference and purchases. Physician prescribing using group depth interviews, attitude instruments, and prescribing panel data were used to test the Fishbein behavioral intentions model. Extensions to the model are presented for marketing applications.

Do self- reported intentions predict clinicians' behaviour: a systematic review

“…In six studies [18-20,22,23,25] the participants were nurses, in three studies they were doctors [16,21,24], and in the one remaining study they were pharmacists [17]. …”

“…The studies covered five types of clinical behaviour: hand hygiene behaviours (e.g., hand washing) [18,20], patient education [16,19,22], clinical record-keeping [23,25], drug choice (prescription) [21,24], and provision of pharmaceutical care [17]. …”

“…Six studies used multiple-item intention measures [17-20,22,23], and four studies used single-item intention measures [16,21,24,25], two of which asked the same item for each of a range of drugs [21,24]. The response format for nine studies was a 7-point scale, scored 1–7 [17,20,22,23,25] or scored -3 to +3 [18,19,21,24].…”

“…The response format for nine studies was a 7-point scale, scored 1–7 [17,20,22,23,25] or scored -3 to +3 [18,19,21,24]. The response format for one study was an estimated percentage, expressed in deciles [16].…”

“…Only three studies [17,23,24] reported the standard error of this correlation or statistics from which it could be estimated, so it was not possible to aggregate the study results in a meta-analysis.…”
