Competitive testing of health behavior theories: how do benefits, barriers, subjective norm, and intention influence mammography behavior?

ABSTRACT:

Background

Competitive hypothesis testing may explain differences in predictive power across multiple health behavior theories.

Purpose

We tested competing hypotheses of the Health Belief Model (HBM) and Theory of Reasoned Action (TRA) to quantify pathways linking subjective norm, benefits, barriers, intention, and mammography behavior.

Methods

We analyzed longitudinal surveys of women veterans randomized to the control group of a mammography intervention trial (n = 704). We compared direct, partial mediation, and full mediation models with Satorra-Bentler χ (2) difference testing.

Results

Barriers had a direct and indirect negative effect on mammography behavior; intention only partially mediated barriers. Benefits had little to no effect on behavior and intention; however, it was negatively correlated with barriers. Subjective norm directly affected behavior and indirectly affected intention through barriers.

Conclusions

Our results provide empiric support for different assertions of HBM and TRA. Future interventions should test whether building subjective norm and reducing negative attitudes increases regular mammography.

Project description:BackgroundInfluenza vaccine hesitancy is a significant threat to global efforts to reduce the burden of seasonal and pandemic influenza. Potential barriers of influenza vaccination need to be identified to inform interventions to raise awareness, influenza vaccine acceptance and uptake.ObjectiveThis review aims to (1) identify relevant studies and extract individual barriers of seasonal and pandemic influenza vaccination for risk groups and the general public; and (2) map knowledge gaps in understanding influenza vaccine hesitancy to derive directions for further research and inform interventions in this area.MethodsThirteen databases covering the areas of Medicine, Bioscience, Psychology, Sociology and Public Health were searched for peer-reviewed articles published between the years 2005 and 2016. Following the PRISMA approach, 470 articles were selected and analyzed for significant barriers to influenza vaccine uptake or intention. The barriers for different risk groups and flu types were clustered according to a conceptual framework based on the Theory of Planned Behavior and discussed using the 4C model of reasons for non-vaccination.ResultsMost studies were conducted in the American and European region. Health care personnel (HCP) and the general public were the most studied populations, while parental decisions for children at high risk were under-represented. This study also identifies understudied concepts. A lack of confidence, inconvenience, calculation and complacency were identified to different extents as barriers to influenza vaccine uptake in risk groups.ConclusionMany different psychological, contextual, sociodemographic and physical barriers that are specific to certain risk groups were identified. While most sociodemographic and physical variables may be significantly related to influenza vaccine hesitancy, they cannot be used to explain its emergence or intensity. Psychological determinants were meaningfully related to uptake and should therefore be measured in a valid and comparable way. A compendium of measurements for future use is suggested as supporting information.

Project description:Many women experience distressing problems with sexual functioning, most commonly in the form of low sexual desire or arousal, difficulties reaching orgasm, or genito-pelvic pain with sexual activity. Although effective treatments are available, more than half of the women who experience distressing sexual problems do not seek professional help. Understanding help-seeking patterns, experiences with treatment providers, and barriers to treatment is crucial to address this underutilization. Examining the role of personal characteristics, sexual problem symptoms, and cognitive factors in explaining the intention to seek treatment can help identify individuals who are most reluctant to seek help. Psychological online interventions are a promising resource to increase the availability of effective treatments. Knowledge about the predictors of women's intention to use internet-delivered treatments, as well as information about personal preferences regarding their scope, can help tailor them to women's needs. To address these research questions, cross-sectional data of 800 women (Mage = 30.49, range = 18-73) were analyzed. While many women considered clinical psychologists to be the most qualified treatment providers, gynecologists were cited as the most likely first point of contact. Among women not utilizing any treatments, many reported a preference for dealing with a sexual problem on their own as a reason not to seek help. Higher help-seeking intention was related to living in a larger city, experiencing higher sexual distress, experiencing pain or difficulties with vaginal penetration, higher self-stigma. and lower sexual assertiveness. Women who were convinced of the effectiveness of psychological online interventions and who appreciated the benefits of anonymity indicated that they were more likely to use them. Understanding what factors influence women's decisions about whether or not to seek professional help for distressing sexual problems is key to reducing the underutilization of available resources and developing treatments that meet their needs and preferences.

Project description:While the public sector authorities and governments struggle to ensure socioeconomic balance at all levels of society, social entrepreneurship is widely known as the optimum solution to societal issues, such as unemployment, social disparities, and ecological imbalances. Despite the fact that the younger generation holds the highest potential to be future social entrepreneurs, a few studies have been conducted to explore the factors that influence their social entrepreneurial intentions (SEI) in developing countries, such as Bangladesh. Furthermore, the empirical studies based on the value-belief-norm (VBN) theory for addressing SEI were scarce in the existing literature. The study aims to measure the influence of Altruistic Values (AV), Traditional Values (TV), Personal Normative Beliefs (NB), Awareness of Consequences (AC), Ascription of Responsibility (AR), Personal Norms (PN), and Social Norms (SN) on SEI implementation of the VBN framework. A combination of web-based and hardcopy surveys was used to collect data from 797 students of higher educational institutes in Bangladesh. The hypotheses and associations between the factors were statistically analysed using structural equation modelling. As a result, it was demonstrated that AV and TV had a notable influence on NB. Similarly, NB showed a significant positive impact on PN and AC, while AC and AR were reported to have a substantial influence on PN. Finally, PN and SN showed a strong impact on SEI. The holistic social entrepreneurship model proposed in this study should be effective for socioeconomic development by incorporating commercially feasible and sustainable principles. Overall, the study findings would assist researchers, current social entrepreneurs and organisations, educational institutes, government agencies, and individual potential entrepreneurs with accurate knowledge and insight to construct their strategies and efficiently pursue social ventures.Supplementary informationThe online version contains supplementary material available at 10.1007/s12144-022-04119-2.
