Charitable donations and the theory of planned behaviour: A systematic review and meta-analysis.

Given the predominance of the theory of planned behaviour (TPB) to represent the psychological determinants underlying people's charitable decisions, the present study synthesised the model's key relationships, using meta-analysis, and tested the predictive utility of the model for charitable giving encompassing donations of blood, organs, time, and money. Given its relevance to altruistic decisions, the impact of moral norm was assessed also. A systematic literature review identified 117 samples (from 104 studies) examining donation intentions and/or prospective behaviour using TPB measures. The sample-weighted average effects for all associations were moderate-to-strong with perceived behavioural control (PBC) most strongly associated with intention (r+ = 0.562), followed by moral norm (r+ = 0.537), attitude (r+ = 0.507), and subjective norm (r+ = 0.472). Intention (r+ = 0.424) showed stronger associations with prospective behaviour than PBC (r+ = 0.301). The standard TPB predictors explained 44% of variance in intention (52% including moral norm). Intention and PBC explained 19% of variance in behaviour. A number of TPB associations showed differences when analysed for moderator variables such as length of follow-up for prospective behaviour and type of target behaviour. Stronger associations were found for the (subjective and moral) norm-intention associations among some of the different types of giving behaviours, especially for donating organs and time. Overall, the large proportion of variance explained by the TPB predictors especially for intention highlights those cognitions associated with people's plans to give, informative for charities reliant on people's propensity to give.

EXERCISE BEHAVIOR IS DETERMINED BY PANDEMIC DISTRESS AND TASK BURDEN AMONG CAREGIVERS OF OLDER ADULTS

Abstract Background Caregivers who have dependents with dementia are at a much higher risk of heart disease and mental illnesses compared with non-dementia caregivers. Consequently, these outcomes have been exacerbated by societal barriers that resulted from the pandemic. Engaging in regular physical activity at a moderate-to-vigorous level (MVPA) is beneficial for caregivers has it has been shown to prevent several adverse health outcomes. However, pandemic-related (COVID-19) distress likely worsened caregiver burden which in turn compromised their MVPA levels. The purpose of this study was to understand how caregiving burden impacts MVPA when accounting for physical activity determinants from an augmented Theory of Planned Behavior (TPB) model. Methods Participants (n=127) were caregivers for older adults (65+) who have dementia. Participants completed measures of MVPA (behavior), TPB, pandemic-related distress (COVID Caregiver Risk Index) and burden scale for family caregivers. The study was investigated using a structural equation model. Results Participants were 45.5 (SD=3.4) years old, 76.4% female. Attitudes (β=.22, p=.012) and perceived behavioral control (β=.19, p<.001) predicted intention. Attitudes and perceived behavioral control mediated the relationship between past behavior and intention (β=.17, p=.02). Covid distress predicted caregiver burden (β=.35, p<.001), and caregiver burden mediated the effects between distress and behavior (β=-.12, p=.01). Conclusions Caregiver burden findings suggest that societal changes and demographic-specific burdens related to caregivers need to be considered for caregivers with dependents who have dementia. Taken together, exercise programs that focus on traditional behavioral determinants also need to include specific approaches to buffer caregiving burden experienced in this demographic.

College students' influenza vaccine hesitation: a reasoned action investigation with quantitative and qualitative data.

This two-wave longitudinal study (performed pre-COVID), using both quantitative and qualitative data, investigated college students’ influenza vaccine hesitancy and confidence using the theory of planned behavior (TPB). At Time 1, college students (n = 277) completed TPB measures and reported past influenza vaccine behavior. At Time 2 (30 days later), participants indicated whether they received the influenza vaccine since Time 1. At Time 2, participants who indicated that they had not received the influenza vaccine since Time 1 also described their most important reasons for not doing so. The TPB model fit the quantitative data well; direct paths from attitude and norms to intention, and from intention to future behavior, were strong and significant. The TPB model explained 71% of the variance in intention and 28% of the variance in future behavior. Neither perceived behavioral control nor past behavior improved the model’s ability to predict intentions or future behavior. From the qualitative data, participants’ reasons for not getting vaccinated focused on perceived behavioral control (e.g., time cost) and attitudes (e.g., unimportance and low susceptibility). Theoretical implications for message development are discussed.

Assessing predictors of self-management intentions in people with type 2 diabetes

BackgroundType 2 diabetes mellitus (T2D) is slowly turning into an international health emergency, evidenced by accelerated growth in prevalence rates worldwide. Experts have now called for greater integration of self-management interventions in clinical practice in light of these worrisome trends, supplanting the prevailing notion of a “glucocentric” approach. In this pilot study designed to complement a novel assessment program currently in development, we describe a concise screening tool designed to stratify the intention to follow through on self-management practices in people with T2D.MethodsA cross-sectional survey was conducted at 3 regional primary care clinics. Individuals with T2D having the following characteristics were recruited into the study: (i) individuals with T2D between 18 and 65 years, (ii) fluent in English and, and iii) having been diagnosed with T2D for at least 2 years. We assessed the relevance of components in the Theory of Planned Behaviour (TPB) within the context of self-management behaviour in T2D. Participants were requested to complete a questionnaire containing questions related to intention, attitudes subjective norm and perceived behavioural control. Based on their responses, the psychometric properties of the scale were then evaluated using both reliability and validity analysis.ResultsThe Cronbach α value for all direct measures of TPB was excellent: intention to adhere to self-management practices (0.98), attitude towards self-management behaviour (0.87), subjective norm (0.83), and perceived behaviour control (0.66). The correlation between intentions and all 3 constructs of TPB was excellent (p < 0.01). Structural equation modeling helped determine attitudes and subjective norms as important predictors of intentions to follow through self-management practices.ConclusionsBy first understanding the dimensions that influence intentions associated with self-management behaviour, clinicians have the opportunity to “triage” individuals with T2D who require greater involvement to bring about better self-care practices. Thus, our research attempts to bridge this gap by devising a psychometric tool suited to a regional setting which allows for an improved person-centered communication between clinicians and patients.

Driving under the influence of drugs or alcohol: Predicting the intentions of young drivers

Objectives: Driving under the influence (DUI) of drugs or alcohol impairs driving performance and, as a result, increases the risk of crashes. The risk of DUI is five-fold higher for young drivers (aged 18-25 years), but little is known about what determines their DUI intentions. This study applied an extended model of the Theory of Planned Behavior (TPB) to address the research question of what factors might influence young drivers' future intentions to DUI. Methods: This study used a survey obtaining data from 329 young drivers (Mage = 20.92 years, SD = 2.16) in Australia. Beyond the standard TPB measures of attitudes, subjective norms and perceived behavioral control (PBC), the current study included demographic variables and additional predictors (i.e., moral norm, peers' norm, perceived risk, impulsivity and past DUI behavior). Results: A vast majority of the participants (85.1%) selected the maximum (9, never), meaning that they had no intention to DUI in the future. Overall, a stepwise multilevel logistic regression analysis (Step 1: demographics, Step 2: TPB measures, and Step 3: additional predictors) explained between 30.1% and 52.9% of the variance in DUI intentions. It showed past DUI behavior as the strongest predictor of DUI intention, followed by instrumental attitude and descriptive norms. Conclusions: This study explored an extended TPB model to understand young drivers' DUI intentions better. With this new knowledge of understanding the factors that influence DUI, researchers and practitioners can create interventions and strategies that are better tailored to the population of young drivers at higher risk.

Supervised Physical Activity Is Important To Counteract Negative Impacts Of Cancer On Physical Activity Behavior

PURPOSE: The theory of planned behavior (TPB) is used to document children’s psychological parameters linked to their physical activity practice to better understand their physical activity behavior. The TPB model evaluates the informational and motivational parameters that contribute to the practice of physical activity. This study aimed to assess the evolution of children’s physical activity levels (MVLPA) during the first months of their cancer, in addition to document the evolution of TPB measures, self-reported fitness and self-esteem in the physical domain to better understand children’s physical activity behavior. METHODS: A total of 16 children (8 boys and 8 girls) with cancer were recruited in the context of the VIE (Valorization, Implication and Education) study. Patients answered psychosocial questionnaires at their diagnosis of cancer (time 1), six to eight weeks following their diagnosis (time 2) and six weeks after the physical activity program (time 3). The physical activity program was composed of two physical activity sessions (≃45min) per week for six weeks at moderate intensity. The integration of the family in the physical activity process was taken into consideration. RESULTS: A significant decrease of 41.2min/day of daily MVLPA was observed between the time at cancer diagnosis (50.5±32.8min/day) and six to eight weeks after the first interview (9.3±9.1min/day). After the physical activity program (23.1±10.8min/day), we observed a significant increase of 13.8 min/day of daily MVLPA. We found that time after the diagnosis of cancer negatively impacted children’s TPB measures (mean in attitude, injunctive norms, identity, facilitating factors, self-confidence and intention) and MVLPA levels, while that the time after the physical activity program positively impacted children’s TPB measures (mean in attitude, injunctive norms, identity, facilitating factors, self-confidence and intention) and MVLPA levels. CONCLUSIONS: This study highlights the need to provide children with physical activity support as soon as the cancer is diagnosed and shows the importance of familial support by injunctive norms to improve children’s physical activity behavior. These findings help to better understand the effect of cancer diagnosis on children’s physical activity behavior

The impact of cancer on theory of planned behavior measures and physical activity levels during the first weeks following cancer diagnosis in children.

The theory of planned behavior (TPB) is used to document children's health behaviors linked to their physical activity. The TPB model and its components have been applied to comprehend the adoption of physical activity along informational and motivational parameters. Thus, this exploratory study aims to assess the evolution of children's physical activity levels (MVLPA) during the first weeks of their cancer, in addition to documenting the evolution of the TPB measures, self-reported fitness, and self-esteem in the physical domain to better understand children's physical activity behavior. A total of 16 children (8 boys and 8 girls) with cancer answered psychosocial questionnaires at the diagnosis of cancer (time 1) and at 6 to 8weeks (time 2) to assess the TPB measures, self-reported fitness, self-esteem in the physical domain, and their daily physical activities. A significant decrease of 41.2min/days of daily MVLPA was observed between the time at cancer diagnosis (50.5 ± 32.8min/days) and 6 to 8weeks after the first interview (9.3 ± 9.1min/days). We found that the time after the diagnosis of cancer negatively impacted children's TPB measures (mean in attitude, injunctive norms, identity, facilitating factors, self-confidence, and intention) and MVLPA levels. The TPB model explains 40% of the variance in MVLPA by the injunctive norms during the first weeks following cancer diagnosis in children. The findings of this study highlight the negative impacts of cancer on children's TPB measures, self-reported fitness, and self-esteem in the physical domain and self-reported MVLPA levels over 4 to 6weeks following the diagnosis. These findings help to better understand the effect of cancer diagnosis on children's physical activity behavior.

Supervisors\u2019 intention to observe clinical task performance: an exploratory study using the theory of planned behaviour during postgraduate medical training

BackgroundDirect observation of clinical task performance plays a pivotal role in competency-based medical education. Although formal guidelines require supervisors to engage in direct observations, research demonstrates that trainees are infrequently observed. Supervisors may not only experience practical and socio-cultural barriers to direct observations in healthcare settings, they may also question usefulness or have low perceived self-efficacy in performing direct observations. A better understanding of how these multiple factors interact to influence supervisors’ intention to perform direct observations may help us to more effectively implement the aforementioned guidelines and increase the frequency of direct observations.MethodsWe conducted an exploratory quantitative study, using the Theory of Planned Behaviour (TPB) as our theoretical framework. In applying the TPB, we transfer a psychological theory to medical education to get insight in the influence of cognitive and emotional processes on intentions to use direct observations in workplace based learning and assessment. We developed an instrument to investigate supervisors intention to perform direct observations. The relationships between the TPB measures of our questionnaire were explored by computing bivariate correlations using Pearson’s R tests. Hierarchical regression analysis was performed in order to assess the impact of the respective TPB measures as predictors on the intention to perform direct observations.ResultsIn our study 82 GP supervisors completed our TPB questionnaire. We found that supervisors had a positive attitude towards direct observations. Our TPB model explained 45% of the variance in supervisors’ intentions to perform them. Normative beliefs and past behaviour were significant determinants of this intention.ConclusionOur study suggests that supervisors use their past experiences to form intentions to perform direct observations in a careful, thoughtful manner and, in doing so, also take the preferences of the learner and other stakeholders potentially engaged in direct observations into consideration. These findings have potential implications for research into work-based assessments and the development of training interventions to foster a shared mental model on the use of direct observations.

Editor's Choice: Consistency tendency and the theory of planned behavior: a randomized controlled crossover trial in a physical activity context

Objective: This study examined the effects of consistency tendency on the predictive power of the theory of planned behavior (TPB) in relation to physical activity behavior.Methods: In this randomized controlled cross-over trial, we recruited 770 undergraduate students from Indonesia who were randomly assigned into two groups. Participants completed physical activity versions of TPB measures at T1 (baseline) and T2 (post 1 week), and the International Physical Activity Questionnaire at T3 (post 1 month). At T1 and T2, the TPB questions were either presented in ensemble-order (i.e., consistency tendency supressed) or alternate-order (i.e., consistency tendency facilitated).Results: The parameter estimates of the model (CFI > .92, TLI > .90, SRMR < .08, RMSEA < .08) aligned with the tenets of TPB. As compared to ensemble-order, a TPB measured in alternate-order yielded stronger cross-sectional relationships, but this pattern did not appear in the prospective relationships in TPB (i.e., intention/perceived behavioral control and behavior).Conclusions: Consistency tendency inflated the factor correlations of cross-sectionally measured TPB variables, but the inflation was not observed in the prospective prediction of behavior. Health psychology questionnaires with items presented in ensemble order may represent a viable means of reducing the confounding effect of consistency tendency.

Randomized Controlled Trial on Effects of a Brief Clinical-Based Intervention Involving Planning Strategy on Self-Care Behaviors in Periodontal Patients in Dental Practice.

Background: Strengthening adherence to self-care behaviors in patients with periodontal disease (PD) and reducing the plaque index is crucial for improving PD treatment. We evaluated the effectiveness of a theory of planned behavior (TPB)-based health education intervention involving a planning strategy on self-care behaviors in patients with PD. Methods: A randomized controlled trial was conducted; 158 and 139 patients comprised the experimental group (EG) and control group (CG), respectively. Both groups received a leaflet, and the EG also received a planning intervention, which was a brief one-on-one counseling session with a planning sheet. Data were collected using a self-administered questionnaire. Results: Between-group comparisons of TPB measures revealed significant differences in all domains when controlling for baseline covariates. The EG exhibited significantly higher levels of action and coping planning than the CG at two-week follow-up (effect size (ES) = 5.54 and 5.57, respectively) and six-week follow-up (ES = 5.66 and 5.66, respectively). Between-group differences in changes of brushing behaviors increased significantly. More frequent use of dental floss was observed in the EG than in the CG at two-week and six-week follow-ups (24.7% and 22.8%, respectively). Conclusions: The intervention involving planning strategy effectively promoted adherence to self-care behaviors in patients with PD.

A Theory of Planned Behavior-Based Program to Increase Physical Activity in Overweight/Obese Military Personnel: A Randomised Controlled Trial.

Designing a health promotion program to increase physical activity may contribute to weight management. The purpose of this study was to investigate a theory of planned behavior (TPB) program to address this problem in military people. Eighty-four obese/overweight military personnel were randomised into the intervention or control group. A questionnaire assessed demographics, aspects of the TPB program, and physical activity levels. Also assessed were blood glucose and lipid levels. The intervention consisted of seven educational sessions based on TPB. Data were collected at baseline and 3months after the intervention. All constructs of the TPB improved between baseline and follow-up in the intervention group (p<.001), while there were no significant changes in the control group (within-group comparisons). Between-group comparisons on TPB measures revealed differences in all domains when results were controlled for baseline covariates. Greater light and moderate physical activity was observed in the intervention group. Body mass index decreased significantly within the intervention group (p<.001). Changes in triglyceride and high-density lipoprotein also favored the intervention over the control group. An intervention based on the TPB may be effective in promoting physical activity and decreasing weight in military personnel who are obese or overweight.

Exploring intentions to teach mathematical problem solving: An application of the Theory of Planned Behaviour

This study examined the beliefs underlying teachers’ decision-making regarding teaching Mathematical Problem Solving (MPS), from the perspective of the Theory of Planned Behaviour (TPB). 375 primary teachers drawn from 50 schools in a large, mainly urban local authority in Ghana, completed a questionnaire assessing the direct TPB measures of attitudinal beliefs (positive/negative consequences), normative beliefs (approving/disapproving significant others), control beliefs (easy/difficult circumstances) and intentions in relation to teaching MPS. In the follow up qualitative phase, six semi-structured teacher interviews were conducted to further explore the quantitative findings. The merged results revealed that teachers’ intentions to teach MPS were influenced by their attitudinal beliefs towards teaching MPS (e.g. stimulate critical thinking, apply mathematics to everyday contexts), their perceptions and actions of important others (e.g. education authorities, pupils and parents), and some perceived control difficulties (e.g. lack of instructional resources and time availability). The results identified both attitudinal and control beliefs as the main determinants of teacher intentions to teach MPS. These findings highlight the key beliefs to target in developing the capacity of schools to support mathematics teachers’ willingness to implement curriculum reform imperatives.

Exploring the application of the Prototype Willingness Model to weight loss dieting behaviour among UK adults

ABSTRACTFrequent weight loss dieting leads to increased BMI and is associated with eating pathologies. Theoretical models can aid the development of interventions to reduce risk behaviours such as frequent dieting if they are able to adequately account for the target behaviour. The Prototype Willingness Model (PWM) may be able to account for weight loss dieting as this behaviour is often associated with social images. This study explored whether the PWM could predict weight loss dieting status over and above the Theory of Planned Behaviour (TPB). One hundred and ninety-two participants (69% female; mode age 35–44) completed PWM and TPB measures and recorded their height and weight. Males were more likely to be non-dieters than females. Frequent dieters had a higher BMI than non-dieters and rated themselves as more similar to the overweight prototype. Prototype perceptions predicted willingness to eat unhealthy foods alone. Similarity to the overweight prototype predicted weight loss dieting status over and above TPB measures and sex. Further research should explore prototype perceptions in an obese/overweight frequent dieting population as this may be a fruitful direction for developing interventions to reduce weight loss dieting.

An investigation of the effect of customer beliefs on the intention to participate in family Takaful schemes

PurposeThe purpose of this study is to apply the theory of planned behavior (TPB) in predicting the intention to participate in family takaful schemes (FTSs) in the United Arab Emirates (UAE). One area of concern for takaful operators is their untapped market and lower market share compared to those of their conventional insurance counterparts. It is possible that the investigation of direct and indirect (belief based) measures of TPB could shed some light on these concerns and possibly offer some assistance to takaful operators.Design/methodology/approachInterrelationships among attitudes, subjective norms, perceived behavioral controls (PBCs) and intention to participate in FTSs were examined. The relationships between behavioral beliefs on attitudes, normative beliefs on subjective norm and control beliefs on PBC were also assessed to fully identify the structures underlying factors measuring intentions. The respondents consisted of 175 Muslims in the UAE. Data were collected using an online survey and analyzed using SPSS.FindingsThis study found that attitudes, subjective norms and PBCs contribute to the prediction of the intention to participate in FTSs. This study used standard multiple regressions to identify an extensive set of specific belief composites this can be used in the prediction of direct measures of TPB and the intention to participate in FTS.Practical implicationsThe findings of this study provide useful information to takaful marketers on how to develop marketing strategies to increase FTS participation. This study suggests that informative and persuasive promotions can be used to improve the penetration rate of FTSs in the UAE.Originality/valueThis study provides insights into previously unaddressed FTS participation in the UAE. Prior work on determining FTS participation has not been applied to both direct and indirect measures of TPB to understand the phenomenon.

Predicting parental support and parental perceptions of child and youth movement behaviors

ObjectivesIn light of a shift to considering the integration of movement behaviors, the purpose of this study was to examine an extended multi-component theory of planned behavior (TPB) framework to predict parent support and parent perceived behavior of the Canadian 24-h movement behaviors in children and youth including light physical activity (LPA), moderate to vigorous physical activity (MVPA), sleep, and screen-time. DesignCross-sectional survey. MethodA representative sample of Canadian parents (N = 1208) with children aged 5–17 years of age, completed measures of TPB, support behaviors, and the four child health behaviors via a panel survey. ResultsControlling for child age, structural equation models showed that child health behavior was predicted by parental support of that behavior (10–27% of variance explained) and intention and perceived capability to support explained support behaviors (42–53% variance explained). The TPB antecedents of intention, however, differed by each health behavior. ConclusionsParental support behaviors are related to perceived child/youth behavior. Parental support is partly dependent on intention and perceptions of parental capability but the interventions to promote the underlying social cognitions behind parental support may be different for MVPA, LPA, sleep, and screen time restriction.

Towards an integration of the health promotion models of self-determination theory and theory of planned behavior among people with chronic pain.

People with chronic pain and related disability often report motivational difficulties with engaging in health-promoting behaviors. Although health promotion models of self-determination theory (SDT) and theory of planned behavior (TPB) have been shown to explain the motivational processes behind health behaviors in the general population, there is limited theoretical research among persons with chronic pain. This study examined the integration of such theories relevant to physical activity and exercise behavior among pain populations. Secondary data analyses were conducted using cross-sectional surveys from 198 participants with chronic musculoskeletal pain recruited from U.S. clinics and community networks. The primary outcome was self-reported physical activity and exercise participation. Predictor variables included pain intensity, functional disability, and SDT and TPB measures. Hierarchical regression analysis was conducted to examine the associations between these variables. Findings demonstrated that in the first step, functional disability was associated with physical activity and exercise; and in the second step, all SDT factors were associated with physical activity and exercise. In the final step of the model, only certain SDT and TPB factors were associated with physical activity and exercise. Despite preexisting pain and functional disability, the findings suggest that health behavior factors from both SDT and TPB are associated with physical activity and exercise participation. This line of research should encourage rehabilitation professionals to recommend regular physical activity and exercise, while simultaneously addressing and monitoring the SDT and TPB factors that are well-timed and appropriate for persons with chronic pain through motivation-oriented rehabilitation approaches.

Applying Ajzen’s Theory of Planned Behaviour: Changing Physical Activity Health Behaviour with Activity-Tracking Technology

Pairing modern day technology with Azjen’s popular Theory of Planned Behaviour, the objectives were to i) determine whether a mobile connected activity-tracking device could change physical activity (PA) health behaviour, ii) test whether the theory of planned behaviour (TPB) could predict participation in physical activity, measured by mobile technology, iii) determine if PA engagement is correlated with mobile communication usage and vehicle journey time. Participants consisted of 41 males and 28 females (N=69), each completing standard TPB measures at baseline. Intervention included a health warning/advice sheet and the physical attachment of an activity-tracking device paired with a mobile application for the duration of two weeks. The data retrieved included the participant’s daily steps count, the participant’s daily time spent travelling by motor vehicle or not, and the participant’s daily amount of mobile communication usage time. A statistically significant increase in activity was observed in the device-wearing group, with a medium effect size. Findings did not support the TPB as a predictor of PA engagement in a technology intervention context. There was no statistical relationship between PA participation and mobile communication usage or vehicle journey time. Findings suggest a basis for developing interventions to include mobile connected devices for improved behavioural health.

Predicting Intentions to Breastfeed for Three Months, Six Months, and One Year Using the Theory of Planned Behavior and Body Satisfaction

ABSTRACTBreastfeeding is one of the top maternal priorities for many organizations, including the World Health Organization (WHO), The American Academy of Pediatrics (AAP), and the Center for Disease Control (CDC). Focusing on the goals of Healthy People 2020, as well as the recommendations of other organizations, this paper investigates the impacts on women’s intentions to breastfeed newborns for 3 months, 6 months, and 1 year. This research used the theory of planned behavior (TPB) as a model to predict intentions for each duration of time. Body satisfaction was included as a moderating variable given research demonstrating a possible connection of body satisfaction to breastfeeding.A survey of 156 pregnant women was conducted. Results demonstrated the importance of the three TPB measures in predicting intentions. Further, significant interactions between body satisfaction and attitudes, as well as body satisfaction and subjective norms were present in predicting intentions to exclusively breastfeed one’s baby from infant to 6 months of age. Theoretical implications are discussed, as well as practical implications for breastfeeding interventions and campaigns.

The process by which perceived autonomy support predicts motivation, intention, and behavior for seasonal influenza prevention in Hong Kong older adults

BackgroundThis study examined the effectiveness of a theoretical framework that integrates self-determination theory (SDT) and the theory of planned behavior (TPB) in explaining the use of facemasks to prevent seasonal influenza among Hong Kong older adults.MethodsData were collected at two time points in the winter in Hong Kong, during which influenza is most prevalent. At Time 1, older adults (N = 141) completed self-report measures of SDT (perceived autonomy support from senior center staff, autonomous motivation for influenza prevention) and TPB (attitude, subjective norm, perceived behavioral control, and intention for influenza prevention) constructs with respect to facemask used to prevent infection. Two weeks later, at Time 2, participants’ acceptance of a facemask to prevent influenza in the presence of an experimenter with flu-like symptoms was recorded.ResultsPath analysis found that perceived autonomy support of senior center staff was positively and significantly linked to autonomous motivation for facemask use, which, in turn, was positively related to intentions to wear facemasks through the mediation of attitude, subjective norm, and perceived behavioral control. However, the effect of intention on facemask use was not significant.ConclusionsResults generally support the proposed framework and the findings of previous studies with respect to intention, but the non-significant intention-behavior relationship may warrant future research to examine the reasons for older adults not to wear facemasks to prevent seasonal influenza despite having positive intentions to do so.

Perceived enjoyment, concentration, intention, and speed violation behavior: Using flow theory and theory of planned behavior

ABSTRACTObjective: Road accidents are an important public health concern, and speeding is a major contributor. Although flow theory (FLT) is a valid model for understanding behavior, currently the nature of the roles and interplay of FLT constructs within the theory of planned behavior (TPB) framework when attempting to explain the determinants of motivations for intention to speed and speeding behavior of car drivers is not yet known. The study aims to synthesize TPB and FLT in explaining drivers of advanced vehicles intentions to speed and speed violation behaviors and evaluate factors that are critical for explaining intention and behavior.Method: The hypothesized model was validated using a sample collected from 354 fully licensed drivers of advanced vehicles, involving 278 males and 76 females on 2 occasions separated by a 3-month interval. During the first of the 2 occasions, participants completed questionnaire measures of TPB and FLT variables. Three months later, participants' speed violation behaviors were assessed.Results: The study observed a significant positive relationship between the constructs. The proposed model accounted for 51 and 45% of the variance in intention to speed and speed violation behavior, respectively. The independent predictors of intention were enjoyment, attitude, and subjective norm. The independent predictors of speed violation behavior were enjoyment, concentration, intention, and perceived behavioral control.Conclusions: The findings suggest that safety interventions for preventing speed violation behaviors should be aimed at underlying beliefs influencing the speeding behaviors of drivers of advanced vehicles. Furthermore, perceived enjoyment is of equal importance to driver's intention, influencing speed violation behavior.
