Background: To provide better patient care,it is very important for the hospital pharmacists to be willing to provide clinical pharmacy services(CPSs).Objectives: To explore the utility of the theory of planned behavior(TPB)model in predicting Chinese hospital pharmacists intention to provide clinical pharmacy services(CPSs),including auxiliary CPSs and core CPSs.Method: Self-administered questionnaires were distributed to 440 hospital pharmacists in 22 general hospitals in seven cities.Descriptive statistical analysis and structural equation model analysis were used.Results: 416 valid questionnaires were collected.Overall,the pharmacists showed a positive intention,attitude,subjective norms(SN),and perceived behavioral control(PBC)over provision of two types of CPSs.The structural equation model analysis found that attitude(p< 0.01,β = 0.12),SN(p< 0.05,β = 0.10),and the pharmacists intention to provide auxiliary CPSs(p< 0.01,β = 0.63)significantly predicted of their intention to provide core CPSs,accounting for 54.0%of its variance.Attitude(p< 0.01,β = 0.35),PBC(p< 0.05,β = 0.12),and past behavior(PB)(p< 0.01,β = 0.15)are significant predictors of pharmacists intention,accounting for 21%of the variance in pharmacists intention to provide auxiliary CPSs.Conclusions: Strategies to improve pharmacists intentions to provide CPSs should focus on helping the individuals related medical care see the value of CPS,altering their perception of social pressure toward core CPSs,and the removal of obstacles that impede the translation of intentions into behavior.
