Intention to perform the behavior

Definition(s):

An indication of an individual's readiness to perform the behavior The most important predictor a desired behavior will actually occur A function of both attitudes towards a behavior and subjective norms toward that behavior

Example:

Prospective study concerning condom use among homosexual men, baseline question: "If I have insertive anal sex during the next two months, I intend to always use latex condoms" Followed by a 5 point very likely / very unlikely response scale

Attitude

Definition(s):

A mental state involving beliefs, feelings, values, and dispositions to act in certain ways A function of the individual's beliefs about the behavior (behavioral beliefs) and the individual's beliefs about the outcomes of performing the behavior (evaluation of behavioral outcomes)

Example:

Prospective study concerning condom use among homosexual men, baseline question: "Always using latex condoms during the insertive anal sex during the next two months would be" Followed by three 5 point evaluative response scales anchored by very good / very bad, very awful / very nice, very pleasant / very unpleasant

Subjective Norm

Definition(s):

An individual's perception of social norms or his/her peers' beliefs about a behavior A function of an individual's normative beliefs and motivation to comply with beliefs

Prospective study concerning condom use among homosexual men, baseline question: "Most people who are important to me think I should always use latex condoms during insertive anal sex during the next two months" Followed by a 5 point very true / very untrue response scale

Behavioral Beliefs

Example:

Prospective study concerning condom use among homosexual men, baseline question: "My partner(s) think I should always use latex condoms during insertive anal sex during the next two months" Followed by a 5 point very true / very untrue response scale

Motivation to comply
