The theory of reasoned action suggests that effective behavior change requires individuals to have:
However, if the investigator has no particular interest in the individual actions that comprise the category, a simpler strategy can be adopted. Participants can be given a description of the behavioral category, and all TPB measures are obtained in relation to the category as a whole. For example, the participants could be told that we are interested in vigorous exercise defined as 30 minutes or more of physical activity that produces a sweat, at least three times a week. The TPB constructs are then assessed with respect to this criterion. Show [Answer / Close]
However, sometimes different beliefs are readily accessible in relation to the behavioral alternatives. For example, if we are interested in travel-mode choice, the beliefs that are readily accessible with respect to using public transportation may not simply be mirror images of using one's car. If practical, therefore, it is recommended that in this case the TPB constructs be assessed in relation to both options under consideration. [Answer / Close]

In the TPB, the beliefs that come readily and spontaneously to mind are assumed to be the prevailing determinants of attitude toward the behavior, subjective norm, and perceived behavioral control. These may not be the beliefs identified when employing focus groups. By encouraging discussion of ideas brought up by individual group members, focus groups can lead to the selection of beliefs that were not readily accessible for most people. [Answer / Close]
There is no requirement of internal consistency (reliability) for behavioral, normative, or control beliefs. If properly elicited and measured, all readily accessible beliefs are retained, even if a given belief does not correlate well with the total set of beliefs. As formative indicators, readily accessible behavioral, normative, and control beliefs are considered to be the determinants of ATT, SN, and PBC; i.e., they are considered to be causal factors. Their effects on intentions are expected to be mediated by ATT, SN, and PBC. [Answer / Close]

Note that internal consistency is not a requirement of the behavioral, normative, and control belief composites because different accessible beliefs may well be inconsistent with each other. Also, if reliability in the sense of temporal stability is also considered important, the questionnaire must be administered a second time and test-retest correlations are computed. Evidence for predictive and construct validity is obtained when research using the measures developed by the investigator supports the predictions derived from the theory. [Answer / Close]

Note that different considerations apply to personal accessible beliefs, i.e., beliefs emitted by the participants themselves. Here, it is assumed that the beliefs listed represent a person's total set of accessible beliefs. Unlike modal accessible beliefs which are the same in number for all participants, different individuals may well hold different numbers of personal behavioral beliefs, different numbers of personal normative beliefs, and different numbers of personal control beliefs. According to the theory, the greater the number of favorable beliefs, the more favorable will be the attitude, subjective norm, or perceived behavioral control. Personal accessible beliefs should therefore be summed, not averaged, because computing a mean would eliminate these theoretically meaningful differences between individuals. [Answer / Close]

Furthermore, even when the goal intention of interest to the investigator is relatively specific (e.g., exercising every weekday in the gym during lunch hour), implementation intentions -- although also very specific as to place, time, and modality -- can be formulated only for positive goal intentions. Thus, it makes little sense to ask where, when, and how you plan to exercise if you have not formed an intention to engage in this behavior. [Answer / Close]
Consider, for example, a woman's belief that breast self-examination allows her to distinguish between benign lumps and malignant tumors. Although factually wrong, this item of "knowledge" would tend to support performing BSE. Thus, we cannot expect a direct correlation between amount of correct factual information on one hand and attitudes, intentions, and behavior on the other. What does the theory of reasoned action say?Two closely associated theories – The Theory of Reasoned Action and the Theory of Planned Behavior – suggest that a person's health behavior is determined by their intention to perform a behavior.
What is the theory of reasoned action quizlet?- The TRA is a cognitive theory concerning the decision to engage in a particular behaviour. - According to this theory, an individuals decision to engage in a behaviour can be directly predicted by their intention to engage in that behaviour.
What is theory of reasoned action and theory of planned behavior?The Theory of Planned Behavior (TPB) started as the Theory of Reasoned Action in 1980 to predict an individual's intention to engage in a behavior at a specific time and place. The theory was intended to explain all behaviors over which people have the ability to exert self-control.
What are the four components of the theory of reasoned action?Overall, the theory of reasoned action consists of behavior, intention to perform the behavior, attitudes, subjective norms, and external variables. These factors play a significant role when recognizing the power of attitude on behavior.
