The Moderated Influence of Perceived Behavioral Control on Intentions Among the General U.S. Population: Implications for Public Communication Campaigns

Profile of gym-goers who do not use performance-enhancement substances

Introduction

Currently the use of prohibited performance-enhancing substances (PES) in fitness and gym settings is a public health concern as adverse health consequences are emerging. Understanding the characteristics of gym-goers who do not use these substances could lead to an important complement to the ongoing research about risk factors for PES use. The aim of this study was to identify the profile of PES non-use in gym-goers.

Methods

In total, 453 gym-goers (mean age = 35.64 years; SD = 13.08 - measure of central tendency location and measure of absolute dispersion, respectively) completed an online survey assessing sociodemographic factors, exercise characteristics, gym modalities, peers, social influence, attitudes, subjective norms, beliefs, intentions, and self-reported use of PES.

Results

Decision Trees showed that being a woman, training less frequently, not practicing bodybuilding and having a negative intention to consume PES were identified as characteristics of non-users of PES.

Discussion

These results may support evidence-based anti-doping interventions to prevent abusive use of PES in the fitness context.

Optimising recruitment to a lung cancer screening trial: A comparison of general practitioner and community-based recruitment

OBJECTIVES

Pre-trial focus groups of the Early detection of Cancer of the Lung Scotland (ECLS) trial indicated that those at high risk of lung cancer are more likely to engage with community-based recruitment methods. The current study aimed to understand if general practitioner (GP) and community-based recruitment might attract different groups of people, and to quantitatively explore the demographic and psychosocial differences between people responding to GP or community-based recruitment.

DESIGN

Secondary data analysis of ECLS trial baseline data.

METHODS

Adults (n = 11,164) aged 50 to 75 years completed a baseline questionnaire as part of their participation in the ECLS trial. The questionnaire assessed smoking behaviour, health state, health anxiety and illness perception. Alongside demographic characteristics, how participants were made aware of the study/participant recruitment method (GP recruitment/community recruitment) was also obtained via trial records.

RESULTS

The likelihood of being recruited via community-based methods increased as deprivation level decreased. Those recruited via the community had higher levels of perceived personal control of developing lung cancer and were more likely to understand their own risk of developing lung cancer, compared to those who were recruited to the trial via their GP. Health state and health anxiety did not predict recruitment methods in multivariable analysis.

CONCLUSIONS

Community and opportunistic screening invitations were associated with uptake in people from less-deprived backgrounds, and therefore might not be the optimal method to reach those at high risk of lung cancer and living in more deprived areas.

A Reasoned Action Approach to Limiting Excessive Social Media Usage Among Adults

The literature on social media suggests a link between use and negative mental health consequences. Numerous theoretical perspectives have attempted to explain the underlying mechanisms for this relationship but are lacking a clear explanation for why some individuals may be negatively impacted by their social media use. Despite a plethora of research on this relationship, minimal research has examined the act of limiting social media use as a promotional behavior. This study takes a fresh approach by investigating attitudinal components that predict intentions to limit social media use via the reasoned action approach. US adults (N = 298) participated in an online survey on excessive social media use. Attitudes, perceived norms, and perceived behavioral control were significant predictors of intentions to limit social media use. In addition, perceived behavioral control was hypothesized to moderate both the attitude to intention and norm to intention relationships in that these associations would be stronger for those with higher control beliefs. Results showed that strong control beliefs strengthened the attitudes to intentions relationship but weakened the norm to intention relationship. Future practical and research directions are discussed to promote limiting social media use and further investigate the negative mental health outcomes of excessive social media.

Behavioral pathways to private well risk mitigation: A structural equation modeling approach

Complex, multihazard risks such as private groundwater contamination necessitate multiannual risk reduction actions including seasonal, weather-based hazard evaluations. In the Republic of Ireland (ROI), high rural reliance on unregulated private wells renders behavior promotion a vital instrument toward safeguarding household health from waterborne infection. However, to date, pathways between behavioral predictors remain unknown while latent constructs such as extreme weather event (EWE) risk perception and self-efficacy (perceived behavioral competency) have yet to be sufficiently explored. Accordingly, a nationwide survey of 560 Irish private well owners was conducted, with structural equation modeling (SEM) employed to identify underlying relationships determining key supply management behaviors. The pathway analysis (SEM) approach was used to model three binary outcomes: information seeking, post-EWE action, and well testing behavior. Upon development of optimal models, perceived self-efficacy emerged as a significant direct and/or indirect driver of all three behavior types-demonstrating the greatest indirect effect (β = -0.057) on adoption of post-EWE actions and greatest direct (β = 0.222) and total effect (β = 0.245) on supply testing. Perceived self-efficacy inversely influenced EWE risk perception in all three models but positively influenced supply awareness (where present). Notably, the presence of a vulnerable (infant and/or elderly) household member negatively influenced adoption of post-EWE actions (β = -0.131, p = 0.016). Results suggest that residential and age-related factors constitute key demographic variables influencing risk mitigation and are strongly mediated by cognitive variables-particularly self-efficacy. Study findings may help contextualize predictors of private water supply management, providing a basis for future risk-based water interventions.

Who is your Fitspiration? An Exploration of Strong and Weak Ties with Emotions, Body Satisfaction, and the Theory of Planned Behavior

Physical inactivity has become an increasingly important concern for public health. "Fitspiration" social media posts may influence attitudes and intentions toward exercising. An online survey (N = 485) was conducted to examine the potential for fitspiration content from weak and strong ties to shape user emotions, attitudes, norms and behaviors related to exercising. Guided by the theory of planned behavior (TPB) and social cognitive theory (SCT), the results show that exposure to fitspiration content from both strong ties and weak ties were significant predictors of particular attitudes, norms, intentions, actual exercise frequency. However, our path analyses reveal significant indirect paths between exposure to fitspiration content and outcomes for weak ties through negative emotions (guilt), but only through positive emotions (hope and curiosity) for strong ties. Additionally, we found evidence that body satisfaction levels do matter in shaping the interrelationships between exposure to fitspiration content, emotions, and our outcome variables. In light of our results, we encourage researchers to consider the inclusion of emotional responses as antecedents to TPB outcomes and for practitioners to consider the role of source in campaign design.

U.S. National Park visitor perceptions and behavioral intentions towards actions to prevent white-nose syndrome

In the United States, the discovery and spread of white-nose syndrome (WNS) has drastically changed how bats and caves are managed. The U.S. National Park Service has been instrumental in the national response to WNS, as it manages extensive cave resources and has a close relationship with the public. However, managers lack information on visitor support for disease prevention measures designed to slow the spread of WNS and minimize human disturbance of vulnerable bat populations. This study utilized the Theory of Planned Behavior to determine how visitor attitudes, subjective norms, and perceived behavioral controls influenced their behavior regarding WNS preventive actions, including participation in educational programming on bats, wearing clothes or shoes in caves that have not been contaminated with the fungus that causes WNS, walking over decontamination mats, and complying with cave closures. During summer of 2019, data were collected using an on-site survey of 1365 visitors to eight U.S. national park units: Oregon Caves, Lava Beds, Carlsbad Caverns, El Malpais, Wind Cave, Jewel Cave, Mammoth Cave, and Cumberland Gap. Visitors were willing to participate in all preventative actions addressed in the survey (77.7%-96.7%). Visitors expressed that engaging in these actions was very desirable (36.0%-65.6%), and their decision to engage in these actions was most strongly influenced by park staff (39.2%-68.8%) or signage (35.5%-61.9%). Attitudes and subjective norms were positive predictors of behavioral intentions for all measures. Perceived behavioral control was not a direct predictor for behavioral intent, but its interaction with attitudes and subjective norms had a moderating influence on intention to comply with multiple WNS preventive actions. With the continued spread of WNS and emergence of other threats to bats, understanding visitor behavioral intent and underlying factors will facilitate successful implementation of preventive actions that are publicly supported and promote conservation of bat populations in U.S. national parks.

Perceived behavioral control as a moderator: Scientists' attitude, norms, and willingness to engage the public

Scientists play important roles in conducting public engagement, but evidence shows that scientists perceive great challenges in doing so. Drawing broadly from the theory of planned behavior (TPB), this study examines factors predicting scientists’ willingness to conduct public engagement. This study further examines how perceived behavioral control (PBC) of conducting public engagement would moderate the relationships between the proposed predictors and scientists’ willingness to conduct public engagement. Using survey data collected from 706 scientists based in Singapore, this study found that attitude toward and personal norms of conducting public engagement, as well as PBC, significantly predicted scientists’ willingness to conduct public engagement. Notably, PBC interacted with attitude toward conducting public engagement, the perceived descriptive norms, the perceived positive media influence, and the perceived negative external norms of conducting public engagement, as well as personal norms of conducting public engagement to predict scientists’ willingness to conduct public engagement. We postulated the key role that the perception of the ease or difficulty plays in motivating scientists to conduct the skill-intensive endeavor explains the significant moderating effects. The theoretical implications on the TPB and the practical implications for public engagement are further discussed.

Sustainable Entrepreneurs of the Future: The Interplay between Educational Context, Sustainable Entrepreneurship Competence, and Entrepreneurial Intentions

The aim of this paper is to understand how sustainable entrepreneurship competence impacts entrepreneurial intentions in two educational contexts: in higher education and in secondary education. We applied the sustainable entrepreneurship framework, which includes six competencies of sustainable entrepreneurship, and the Theory of Planned Behavior. The data were gathered from seven European countries and consist of 486 responses from higher education students and 642 responses from secondary-level students. The results show that sustainable entrepreneurship competence (SEC) is a significant factor that can explain entrepreneurial intentions. It has a significant direct effect on entrepreneurial intentions in both educational contexts. Perceived behavioral control (PBC) moderates the relationship between SEC and entrepreneurial intentions; the effect of SEC decreases when PBC increases. The moderating effect was found only with higher education students, not with secondary-level students. This study demonstrates a connection between sustainable entrepreneurship competence and entrepreneurial intentions and contributes to a better understanding of the role of sustainable entrepreneurship competence in shaping students’ aspirations for an entrepreneurial career in different educational contexts.

What drives people's intention toward live stream broadcasting

Purpose

The study aims to examine the relationships among personality traits (i.e. the Big Five personality traits and locus of control), self-perceived facial attractiveness, motivations (i.e. intrinsic and extrinsic motivation) and intention toward live stream broadcasting. It also investigates the moderating role of perceived behavioral control in the relationship between motivations and intention.

Design/methodology/approach

Data collected from a sample of 637 participants are used to examine the research model and test the hypotheses with the employment of partial least squares structural equation modeling.

Findings

The study shows that motivations and perceived behavioral control are significant predictors of intention. Perceived behavioral control has a significant moderating effect between motivations and intention. Intrinsic motivation is positively influenced by self-perceived facial attractiveness, agreeableness, extraversion and internal locus of control, while extrinsic motivation is positively predicted by self-perceived facial attractiveness, conscientiousness and extraversion.

Originality/value

This study enhances our understanding of the determinants of intention toward live stream broadcasting by exploring its relationships with motivations, self-perceived facial attractiveness and personality, as well as the moderating effects of perceived behavioral control.

Examining an Integrative Cognitive Model of Predicting Health App Use: Longitudinal Observational Study

BACKGROUND

Specifying the determinants of using health apps has been an important research topic for health scholars as health apps have proliferated during the past decade. Socioeconomic status (SES) has been revealed as a significant determinant of using health apps, but the cognitive mechanisms underlying the relationship between SES and health app use are unknown.

OBJECTIVE

This study aims to examine the cognitive mechanisms underlying the relationships between SES and use of health apps, applying the integrative model of behavioral prediction (IM). The model hypothesizes the indirect influences of SES on intentions to use health apps, which in turn predict actual use of health apps. The relationships between SES and intentions to use health apps were assumed to be mediated by proximal variables (attitudes, perceived behavioral control [PBC], injunctive norms, and descriptive norms).

METHODS

We conducted path analyses using data from a two-wave opt-in panel survey of Korean adults who knew about health apps. The number of respondents was 605 at baseline and 440 at follow-up. We compared our model with two alternative theoretical models based on modified IM to further clarify the roles of determinants of health app use.

RESULTS

Attitudes (β=.220, P<.001), PBC (β=.461, P<.001), and injunctive norms (β=.186, P<.001) were positively associated with intentions to use health apps, which, in turn, were positively related to actual use of health apps (β=.106, P=.03). Income was positively associated with intentions to use health apps, and this relationship was mediated by attitudes (B=0.012, 95% CI 0.001-0.023) and PBC (B=0.026, 95% CI 0.004-0.048). Education was positively associated with descriptive norms (β=.078, P=.03), but descriptive norms were not significantly related to intentions to use health apps. We also found that PBC interacted with attitudes (B=0.043, SE 0.022, P=.046) and jointly influenced intentions to use health apps, whereas the results did not support direct influences of education, income, and PBC on health app use.

CONCLUSIONS

We found that PBC over using health apps may be the most important factor in predicting health app use. This suggests the necessity of designing and promoting health apps in a user-friendly way. Our findings also imply that socioeconomic inequalities in using health apps may be reduced by increasing positive attitudes toward, and boosting PBC over, health app use among individuals with low income.

To Comply or Not to Comply: Roma Approach to Health Laws

According to the general public in Slovakia, compliance with the law is problematic when it comes to Roma and health. Roma compliance with laws has not yet been studied. The aim of this is study was to explore the determinants of Roma behavior in the field of health laws. We used the concept of a semi-autonomous field proposed by Moore (1973) and the theory of planned behavior by Ajzen (1985). We found that Roma (non-)compliance with health laws was influenced by many different factors, such as beliefs, traditions, living conditions and culture. Group beliefs overrule national laws and also individual preferences, which tend to be subordinate to the group view. The less contact Roma from settlements have with non-Roma, the stronger their own rules are in the field of health. Roma health status is influenced by many factors: group beliefs and community traditions are stronger and overrule individual and state behavioral influence. A community-based participatory approach together with improvement of living conditions in cooperation with Roma is desirable.

Parental Guidance and Children's Healthy Food Consumption: Integrating the Theory of Planned Behavior with Interpersonal Communication Antecedents

The study of parenting practices on child food consumption has often been characterized as having great utility but lacking in theory. In contrast, the theory of planned behavior (TPB) has often been suggested to be limited in its utility. To address these gaps, interpersonal constructs - the concepts of active parental guidance (e.g., nutrition education) and restrictive parental guidance (e.g., rule-setting) - were integrated as antecedents to the original TPB variables in predicting child fruits and vegetables (FV) consumption. We surveyed 210 child/adolescent participants, aged between 10 and 16 in Singapore. Results from structural equation modeling showed that the integrative TPB model displayed an acceptable fit. Parental active guidance was associated with all three proximal predictors of behavior. Our results suggest that there are promising contributions to the theory of planned behavior in predicting child food consumption behavior by considering interpersonal antecedents.
