The principal defect of this account is that it makes the belief component of intention epiphenomenal.
The contribution of TPB components to intention decreased from 63% at baseline to 47% at 12 weeks of intervention study.
This study extends earlier work by examining the relative importance of the model components as predictors of intention to cross for four different adult age groups, men, women, drivers and nondrivers.
While PBC is arguably the most important component of behavioral intentions (Armitage & Conner 2001), there has been some debate about how exactly PBC should be operationalized.
Section A contained 18 items based on the components of the extended TPB (Intention, Attitude, Subjective norm, Perceived Behavioural Control and Anticipated regret), with items measured on 7-point response scales with consistent direction (ie, high scores indicating high intention, Perceived Behavioural Control and Anticipated regret, positive Attitude and more positive normative pressures).
Multiple regression analyses demonstrated that components of task value predicted intentions to attend graduate school.
The results suggested that the intention process happened 200 to 400 ms after the cue stimuli was onset, and the P2 in the posterior scalp during this period could be a specific component that related with the process of intention.
Moreover, a previous study among physicians also identified only the cognitive component of attitude as a determinant of intention to adopt a medically-related behavior (i.e., shared decision-making in home care programs) [ 40].
What is clear from this and other studies is that there is a clear association between certain components of nurses job satisfaction and intention to stay (or leave) the profession or organization [ 1, 5].
This model was derived from the HIS evaluation framework and the TAM and incorporates the characteristics of the different types of user (physician, MRS, and patient) with the distinct aspects (organization, human, and technology) involving various extracted components of attitude (Concern, Function, and Intention).
