Testing a Model of Mammography Intention¹

Abstract

This paper presents the results of a study testing components of the Triandis model of choice to predict intention to obtain screening mammography in the next 2 years. A questionnaire was developed to measure the theoretical components of this model. Analysis was based on 2,521 women, 50 to 65 years old, who received primary care from 1 of 28 participating primary care group practices. Based on the four theoretical components of intention described in the Triandis model‐social influence, affect, consequence, and barriers‐a set of structural equation models was explored. The sample was split into two equal subsamples: one sample used for model exploration and one used for model confirmation. Results showed that the original intention model was not supported. Instead, the model that best fit the data, and upheld it in the subsample used for model confirmation, was a model in which habit and intention were strongly related. The strongest predictors of habit were barriers and consequences; the strongest predictors of intention were social influences and barriers.

Competitive Testing of Health Behavior Theories: How Do Benefits, Barriers, Subjective Norm, and Intention Influence Mammography Behavior?

“…In addition, subjective norm did not have a direct influence on intention, as argued by the TRA, but was mediated by perceived barriers (Hypothesis 3). This finding contrasts with previous studies that reported a positive association between subjective norm and intention when controlling for attitudes (i.e., benefits and barriers) (7, 39–42). This may be due to different measures of subjective norm.…”

Prediction of intern attendance at a seminar-based training programme: a behavioural intention model

“…Baumann et al . point out that a simple weighted sum rule may represent a more rational model than typically occurs in human decision making 12 . In the literature, the application of variables in behavioural intention models and their exploration as response modifiers is varied 8 .…”

Disclosure of maternal HIV infection to children among Chinese women with HIV: The application of the Theory of Planned Behaviour and the role of various norms

“…It has been suggested that intention is more subject to be influenced by significant others when a behaviour is not well-incorporated into one's repertoire (Baumann, Brown, Fontana, & Cameron, 1993). Furthermore, a lack of personal experience would lead individual to rely more on views of significant others in performing a behaviour (Baumann et al, 1993). Therefore, participants who had no prior experiences in disclosing HIV status would value the views of others in disclosing HIV status.…”

“…The findings that descriptive and injunctive norms were significant factors to HIV disclosure intention were consistent with previous studies, which reported the positive influence of significant others on the intention to disclose. It has been suggested that intention is more subject to be influenced by significant others when a behaviour is not well‐incorporated into one's repertoire (Baumann, Brown, Fontana, & Cameron, ). Furthermore, a lack of personal experience would lead individual to rely more on views of significant others in performing a behaviour (Baumann et al, ).…”
