Intention to adopt a healthy diet among women with and without a history of gestational diabetes: Constructs and beliefs from the theory of planned behavior.

ABSTRACT: Women with a history of gestational diabetes (GDM) have difficulty maintaining a healthy diet after delivery. The theory of planned behavior (TPB) is effective in identifying the determinants of adopting a healthy diet. The objectives were to identify the determinants of the intention to adopt a healthy diet among the TPB constructs in women with (GDM+) and without (GDM-) a history of GDM, and to identify the beliefs associated with these constructs. The study was conducted in Québec (Canada) between 2009 and 2017. Data from 213 GDM+ and 91 GDM- women were analyzed. Women completed a questionnaire on the determinants of intention to adopt a healthy diet, defined as adherence to 2007 Canada's Food Guide. The subjective norm and perceived behavioral control (PBC) constructs were associated with the intention to adopt a healthy diet among GDM+ women (β = 2.21 and β = 4.37, respectively, p < 0.0001), whereas among GDM- women, PBC was the only construct associated with intention (β = 0.78; p < 0.0001). More specifically among GDM+ women, the disapproval of a family member other than the partner (β = 1.49; p = 0.0005), not feeling capable of adopting a healthy diet with access to food treats (β = 1.58; p < 0.0001), lack of free time (β = 1.31; p = 0.002), lack of information about healthy eating (β = 1.02; p = 0.015) or lack of easy recipes to prepare (β = 0.84; p = 0.042) was associated with a lower intention to adopt a healthy diet. Overall, among GDM+ women, different beliefs related to the subjective norm and PBC could be targeted to improve the eating habits of this specific population.

Project description:BackgroundEven though evolution is the overarching principle that connects all areas of biology, a significant proportion of pre-service teachers do not intend to teach evolution, minimize the teaching of evolution, or teach alternative ideas in biology classes. To prevent adverse teaching practices and promote effective pre-service teacher education, we aimed to identify and analyze variables that foster or hinder their behavioral intentions to teach evolution.MethodWe adopted a behavioral psychology research perspective and developed a research model based on the theory of planned behavior to examine behavioral intentions for teaching evolution in biology classrooms. We extended the model with additional variables that have been delineated by teacher education research as essential determinants for the behavioral intention to teach evolution. We proposed several hypotheses suggesting that the attitude toward teaching evolution, subjective norms, perceived behavioral control, personal religious faith, perceived usefulness, and knowledge about evolution determine a person's behavioral intention. We conducted a quantitative cross-sectional study in teacher education to test the hypotheses and surveyed N = 339 pre-service biology teachers using an online questionnaire. We analyzed the data using a two-stage structural equation model.ResultsWe were able to confirm all proposed hypotheses. The most important results revealed that pre-service teachers' knowledge about and perceived usefulness of evolution are only moderately pronounced. Moreover, the subjective norm is a predictor not only of behavioral intention but also of the attitude toward teaching evolution. The variable of perceived behavior control partly moderates the relationship between knowledge about evolution and behavioral intention. Additionally, perceived usefulness is an important and marginally stronger predictor of a person's attitude than personal religious faith.ConclusionThe extended model of the theory of planned behavior has highlighted the need for educational programs to increase knowledge about and the perceived usefulness of evolution even stronger. The findings delineated the effects of essential determinants on behavioral intentions and provided information about the necessary levers of teacher education.Supplementary informationThe online version contains supplementary material available at 10.1186/s12052-022-00175-1.

Project description:BackgroundBlood shortage is a persistent problem affecting Taiwan's health-care system. The theory of planned behavior (TPB) has been commonly used in studies of health advocacy. The purpose of this study was to develop a questionnaire measuring clinicians' intention to prescribe transfusion based on the TPB.MethodA questionnaire comprising 15 items for assessing clinicians' intention to prescribe blood transfusion was developed, and it collected demographic characteristics, tested patient blood management (PBM) and perceived knowledge of PBM. Furthermore, the questionnaire contained four subscales related to the TPB. A total of 129 clinicians participated in this pilot study between July and December2020. Item analysis and exploratory factor analysis were conducted to examine the validity and reliability of this measurement instrument.ResultsThe results indicated no statistically significant correlations between the demographic characteristics and PBM test scores. Regarding perceived knowledge, the results of a one-way analysis of variance revealed that the effect of age, hierarchy of doctors, and education level were significant. In terms of subjective norms, a significant effect on education level was noted [t (129) = 2.28, p < 0.05], with graduate school graduates receiving higher scores than college graduates. An analysis of variance demonstrated the effects of hierarchy, education level, and medical specialty on perceived behavioral control. The results of the regression analyses revealed that perceived knowledge (β = 0.32, p < 0.01) and subjective norms (β = 0.22, p < 0.05) were significantly related to clinicians' behavioral intentions.ConclusionsThis study revealed that factors affecting clinicians' blood transfusion management can be explained using the TPB-based questionnaire. This study demonstrated that physicians' perceptions of whether most people approve of PBM and their self-assessment of their PBM knowledge affect their intentions to proceed with PBM. According to this finding, a support system among physicians must be established and maintained to increase physicians' confidence in promoting PBM.

Project description:BackgroundCervical cancer is the most common malignant tumor in women with a high mortality rate. However, the awareness and participation of women in cervical cancer screening were not high, and rare attention was paid to cervical cancer screening. The extensive promotion and execution of cervical cancer screening in China are still facing difficulties. In order to fully comprehend and evaluate the barriers and promote factors of cervical cancer screening in women, the objective of this study was to develop a scientifically sound and clinically useful Chinese cervical cancer screening intention scale. This study would allow for the development of targeted interventions which may contribute to the increase of individual participation in cervical cancer screening going forward.MethodsThis study used the Delphi method to construct a Chinese cervical cancer screening intention scale based on the theory of planned behavior (TPB) and evaluate its validity. The study was based on the overview of the TPB questionnaire proposed by Ajzen, and was conducted through the literature search and two rounds of the Delphi expert consultation. According to the literature search published from 2012 to 2022, the scale item pool was established and a questionnaire was designed. A survey of 16 experts from 6 different provinces, cities and regions in China was conducted, and the Delphi technique was used to collect and analyze expert opinions data.ResultsThe final scale consisted of 4 dimensions and 23 items. The response rates in two rounds of expert consultation were 80% and 93.75%, respectively, with authority coefficients of 0.928 and 0.930. Variation coefficients varied from 0.07 to 0.21. Dimensions included "attitude towards behavior", "subjective norm", "perceived behavioral control" and "behavioral intention".ConclusionsWomen's cervical cancer screening intentions could be assessed with the scale, since it had high validity and reliability, as well as high authority and coordination, meanwhile affording explanations and improving the efficiency of interventions.
