An Elicitation Study to Understand Young Adults' Beliefs About Seeking Health Information From Social Media Influencers.

Social media influencers increasingly make health recommendations on social media. Research on influencer health messaging is mixed in that some studies show it can result in misleading or harmful health information, and others demonstrate it can lead to beneficial behavioral outcomes. However, there is little research on young adults' beliefs about following health guidance from influencers. Guided by the reasoned action approach, this study examined young adults' attitudes, normative beliefs, and control in seeking health information from social media influencers using focus groups (n = 31). Results suggest that young adults obtain health information from influencers and perceive them as a source of health education. Several barriers to getting health information from influencers were mentioned, including sponsorship, lack of credibility, and perceived normative pressure to critically analyze influencer content from peers and family. Practical and theoretical implications for future research are discussed.

An application of the reasoned action approach to clinical students' intention toward a career in geriatrics.

Guided by the reasoned action approach, this study examined select individual, information, and social factors that influence intention toward pursuing a career in geriatrics among 314 clinical medical and nursing students in Ghana. A Poisson regression showed attitude toward older persons was a significant influencing factor of intention to choose a career in geriatrics for medical students (B = 0.015, SE = 0.0048, p = 0.002) but not nursing students (B = 0.009, SE = 0.0145, p = 0.512). Personal interest was, however, a significant influencing factor for both medical and nursing students (B = 0.462, SE = 0.0592, p = 0.000) and (B = 0.015, SE = 0.0048, p = 0.002), respectively. Nursing students with moderate to strong interest were 1.6 times more likely to express an intention to specialize in geriatrics, and medical students were 1.5 times more likely to express an intention to specialize in geriatrics. The results show that the most important factor influencing geriatric career intention is students' personal interest in the field. Evidence-based interventions such as early educational and practice exposure to the field and interactions with older adults are recommended.

A reasoned action approach to meditation behavior among cadets at the United States Military Academy.

Military members face emotion-regulation challenges due to the high-pressure nature of the profession as evidenced by rates of mental health issues within military populations. Identifying behaviors that are efficient and effective at promoting emotion-regulation and helping military members adopt them is essential. Recently, meditation has been shown to reduce stress, enhance attention control and emotion regulation, along with reducing military-related Post Traumatic Stress Disorder symptoms. One way to promote this behavior in a military context is to enable future officers to adopt the behavior. We aimed to examine determinants of meditation intention and behavior among cadets at the United States Military Academy using the Reasoned Action Approach, a behavior framework used to explain and change behavior. By identifying these determinants, military practitioners can tailor meditation interventions to increase the likelihood that cadets will adopt the practice and eventually help soldiers under their command use meditation as well. We conducted a pilot study and a replication study that confirmed Reasoned Action Approach constructs were predictive of behavior and behavioral intention. Of significance was the perceived norm impact on meditation intention, specifically injunctive norms. Implications include the importance of authority figures within cadets' social context providing support for meditation's utility.

How Does Self-Control Promote Health Behaviors? A Multi-Behavior Test of Five Potential Pathways.

BACKGROUND: Self-control is generally defined as the capacity to override impulses and is a robust predictor of health behaviors. This paper integrates trait, reasoned action, and habit approaches to develop and test a mechanistic account of how self-control influences health actions. PURPOSE: We tested five potential pathways from self-control to behavior, termed the valuation, prioritization, habituation, translation, and inhibition routes. METHODS: At baseline, participants (N = 663 adults) completed survey measures of reasoned action approach variables and habits in relation to eight health behaviors and the Brief Self-Control Scale. Three months later, participants reported their behavior. Multi-level modeling was used to test pathways across behaviors. RESULTS: Supporting the valuation route, affective attitude, cognitive attitude, descriptive norms, and perceived behavioral control mediated the self-control-intention relation, and intentions and perceived behavioral control mediated the relationship between self-control and health behaviors. Self-control also predicted the priority accorded to different considerations during intention formation. Higher self-control was associated with stronger prediction by cognitive attitudes and perceived behavioral control and weaker prediction by habits and injunctive norms. Self-control predicted habit formation, and habits mediated the self-control-behavior relation. Finally, self-control was associated with the improved translation of intentions into health behaviors and with greater inhibition of affective and habitual influences. Findings for the different pathways were not moderated by whether approach (health-protective behaviors) or avoidance responses (health-risk behaviors) were at issue. CONCLUSIONS: The present research offers new insights into why self-control promotes health behavior performance, and how deficits in self-control might be offset in future behavior-change interventions.

Self-control is the capacity to override impulses and is known to predict engagement in health behaviors. This article tests five hypotheses about how self-control drives health actions. We find that high self-control not only helps to override impulses (feelings and habits), it also influences (a) how favorable are people's thoughts, feelings, and intentions about health behaviors, (b) what considerations determine the intention to act (e.g., high self-control means people give higher priority to the perceived healthiness of the behavior and how much control they have over its performance), (c) whether people form habits that make it less effortful to perform health behaviors, and (d) how effectively people translate their "good" intentions into health behaviors. Thus, we find support for five different routes from self-control to engagement in health behaviors.

How does a school-based intervention impact students' social cognitions on reducing sedentary behavior over 14 months?

Despite sedentary behavior being ubiquitous in students and detrimental to health, interventions specifically targeting it are mostly restricted to leisure time screen time reduction. With six weekly sessions alongside a poster campaign and an additional teacher intervention, the Let's Move It trial delivered environmental and psychological strategies to increase physical activity (PA) and reduce sedentary behavior (SB) in vocational schools, an understudied environment for behavioral interventions. Participants in the intervention arm considerably reduced sedentary time post-intervention. To investigate how social cognitions about restricting SB, as defined by the Reasoned Action Approach, change in intervention and control arms, self-reported data on social cognitions was collected as part of a cluster-randomized controlled trial from 1166 students (59% female, mage = 18.7 years, range: 16-49) in six vocational schools before, post-intervention, and 14 months post-baseline. Data were analyzed using mixed between-within repeated measures ANOVA. We found greater improvements in intention (F(1, 833) = 9.69; η2p = 0.01; p = .018) and descriptive norms (F(1, 831) = 13.25; η2p = 0.016; p < .001) in the intervention than control arm, but these effects depended on the included control variables. Generally, intervention effects leveled off from post-intervention to follow-up. The Let's Move It intervention for SB reduction showed modest, short-lived effects on social cognitions, indicating that changes in behavior are likely due to other factors like changes to the classroom environment. Optimally, SB reduction interventions should not only change behavior but produce robust changes in conscious intentions to restrict one's sitting, so that positive effects generalize to other contexts.

Urban Youth Perceptions of Sports and Energy Drinks: Insights for Health Promotion Messaging.

Objective: This study aimed to examine urban adolescents' beliefs about sports and energy drinks to identify factors for health messaging to discourage youth consumption. Design: Focus group study involving thirty-four adolescents in urban areas (12 female, 12 male, and 10 unreported sex; 19 Hispanic, 11 Non-Hispanic Black, 2 Asian, and 1 unknown race or ethnicity). Setting: Four focus groups were conducted with adolescents in urban areas. Method: Each on-time moderated group discussion was structured to generate an inventory of attitudinal, normative and efficacy beliefs associated with sports and energy drink consumption and reduction. Thematic analysis was used to analyse the data. Results: Attitudinal and normative beliefs were more positive towards sports drink consumption and energy drink reduction. Misperceptions about the need for sports drinks to avoid dehydration during physical activity were evident. Product accessibility and advertising pervasiveness were facilitators influencing consumption and barriers to reduction for both products. Conclusion: Results highlight important differences in perceptions about sports and energy drinks that indicate the need for different approaches and messages for interventions designed to curb consumption of these products. Recommendations for message design are provided.

Understanding intention and use of digital elements in higher education teaching.

Digital elements are being increasingly used in higher education teaching, but the intention and their actual use vary depending on the lecturers. We used the reasoned action approach to understand the beliefs and intentions behind the use of digital elements in this context. We conducted a quantitative survey in which university lecturers shared their intention concerning the use of digital learning elements and indicated their actual use. The results confirm the influence of attitude, perceived norms, and perceived behavioral control on the intention to use digital learning elements. However, we also identified an intention-behavior gap: Only one-time effort to become familiar with digital elements has a significant impact on actual usage. We conclude that, above all, teachers must first be given the opportunity to become familiar with digital learning elements to be able to use them effectively. Understanding why such an intention-behavior gap exists should be the aim of future studies.

Does Temporal Stability Moderate Reasoned Action Approach Relations With Covid-19 Preventive Behaviors?

BACKGROUND: Preventive behaviors continue to play an important role in reducing the spread of the SARS-CoV-2 virus. PURPOSE: This study aimed to apply the reasoned action approach (RAA) to predict Covid-19 preventive intentions and behavior and to test whether temporal stability moderates relations between RAA constructs and behavior. METHODS: A representative sample of UK adults (N = 603) completed measures of RAA variables (i.e., experiential attitudes, instrumental attitudes, injunctive norms, descriptive norms, capacity, autonomy and intention) in relation to six Covid-19 preventive behaviors (i.e., wearing face coverings, social distancing, hand sanitizing, avoiding the three Cs [closed spaces, crowded places, and close contacts], cleaning surfaces, and coughing/sneezing etiquette) at baseline (December 2020) and after 1 month. Self-reported behavior was assessed at baseline and after 1 and 2 months. RESULTS: The RAA was predictive of Covid-19 preventive intentions at time 1 and time 2; instrumental attitudes, descriptive norms, and capability were the strongest predictors at each time point. The RAA also predicted subsequent behavior across time points with intention, descriptive norms, and capability the strongest/most consistent predictors. Temporal stability moderated a number of RAA-behavior relationships including those for intention, descriptive norms, and capability. In each case, the relationships became stronger as temporal stability increased. CONCLUSIONS: Health cognitions as outlined in the RAA provide appropriate targets for interventions to promote Covid-19 preventive intentions and behavior. Moreover, given that continued performance of Covid-19 preventive behaviors is crucial for reducing transmission of the SARS-CoV-2 virus, the results highlight the need for consistent messaging from governments and public health organizations to promote positive intentions and maintain preventive behavior.

Awareness, acceptability, and intention to initiate HIV pre-exposure prophylaxis among pregnant women.

HIV prevention is critically important during pregnancy, however, pre-exposure prophylaxis (PrEP) is underutilized. We conducted a survey of pregnant and non-pregnant women in a high HIV prevalence community in Washington D.C. to evaluate determinants of PrEP initiation during pregnancy. 201 pregnant women and a reference population of 1103 non-pregnant women completed the survey. Among pregnant women, mean age was 26.9 years; the majority were Black with household-incomes below the federal poverty level. Despite low perceived risk of HIV acquisition and low prior awareness of PrEP, 10.5% of respondents planned to initiate PrEP during pregnancy. Pregnant women identified safety, efficacy, and social network and medical provider support as key factors in PrEP uptake intention. The belief that PrEP will "protect (their) baby from HIV" was associated with PrEP uptake intention during pregnancy. Concerns regarding maternal/fetal side effects, and safety in pregnancy or while breastfeeding were not identified as deterrents to uptake intention. When compared to a nonpregnant sample, there were no significant differences in uptake intention between the two samples. These findings support the need for prenatal educational interventions to promote HIV prevention during pregnancy, as well as interventions that center on the role of providers in the provision of PrEP.

Factors Associated with Intention to Initiate Pre-exposure Prophylaxis in Cisgender Women at High Behavioral Risk for HIV in Washington, D.C.

Pre-exposure prophylaxis (PrEP) for HIV prevention is underutilized by cisgender women at risk for HIV in the USA. Published research on PrEP initiation among cisgender women at risk for HIV focuses on identifying barriers and facilitators associated with intention to initiate, but few apply a behavioral theoretical lens to understand the relative importance of these diverse factors. This study provides a theoretically grounded view of the relative importance of factors associated with intention to initiate PrEP. We conducted an anonymous, cross-sectional survey of 1437 cisgender women seeking care at family planning and sexual health clinics to evaluate hypothesized barriers and facilitators of PrEP initiation. We categorized cisgender women with ≥ 3 behavioral risk-factors as "high-risk" for HIV acquisition; 26.9% (N = 387) met high-risk criterion. Among cisgender women in the high-risk sample, the majority were Black and single. Perceived risk of HIV acquisition was low and 13.7% reported intention to initiate PrEP. Positive attitudes toward PrEP, self-efficacy, perceived support from medical providers and social networks, and prior discussion about PrEP with medical providers were associated with intention to initiate PrEP; stigma was negatively associated. Background characteristics (other than age), risk factors for HIV acquisition, prior awareness of PrEP, and perceived risk of HIV were not associated with uptake intention. These findings support interventions that center on the role of providers in the provision of PrEP and on social networks in destigmatization of PrEP use.

Predicting exercise after university: an application of the reasoned action approach across a significant life transition.

The present study applied an extended version of the reasoned action approach (RAA) to explain students' post-university exercise intentions and behaviour. Students (N = 136) completed measures of RAA variables, past behaviour, habit strength and self-identity before leaving university, and exercise behaviour six months later (n = 84). The RAA explained 67% of the variance in exercise intentions (experiential attitude, instrumental attitude and autonomy were significant predictors), and 20% of the variance in behaviour (experiential attitude and intention were significant predictors). Past behaviour explained additional variance in exercise intentions and behaviour, but its effects were mediated by self-identity. The RAA provides a useful framework for understanding students' exercise intentions and behaviour as they transition out of university. Self-identity may be particularly important for maintaining exercise levels across significant life transitions.

Cognitions and behaviours of general practitioners in France regarding HPV vaccination: A theory-based systematic review.

Human papillomavirus (HPV) vaccination is safe and efficacious to prevent persistent HPV infection, precancerous anogenital lesions and cervical cancer. However, in countries where vaccination programmes are implemented outside of schools, such as France, reaching high HPV vaccination coverage of the target population is challenging. Many studies have been performed in France to assess cognitions of general practitioners (GPs) regarding HPV vaccination. However, the evidence is not consistent about which cognitions are key. To provide a comprehensive overview, we performed a systematic review of studies conducted in France on GPs' cognitions regarding HPV vaccination and used the reasoned action approach to extract and synthesize data. The systematic search was performed up to July 2020 in Medline via PubMed, PsycINFO, PsycARTICLES, Embase, CINAHL Plus, Web of Science, Pascal and Francis databases. Grey literature was searched for in the French Public Health Database, Cairn. Info, yahoo.fr, and Google Scholar. Twenty-five scientific publications were selected based on eligibility criteria and assessed for quality. Our qualitative synthesis highlights that although 73% of GPs report recommending HPV vaccination, up to 50% would not recommend it because of concerns, including changes in patients' health behaviours and doubts about safety and/or efficacy. GPs' injunctive norms, i.e. trust in institutional information, were shown to be associated positively with GPs' willingness to recommend HPV vaccination. Parents' fears, girls' age, and potential connection with sexuality do not seem to affect GPs' recommendations. These results will inform the development of a professional educational intervention targeting GPs in France.

Factors Influencing the Intention of Actors in Hospitals to Use Indoor Positioning Systems: Reasoned Action Approach.

BACKGROUND: Indoor positioning systems (IPS) have become increasingly important for several branches of the economy (eg, in shopping malls) but are relatively new to hospitals and underinvestigated in that context. This research analyzes the intention of actors within a hospital to use an IPS to address this gap. OBJECTIVE: To investigate the intentions of hospital visitors and employees (as the main actors in a hospital) to use an IPS in a hospital. METHODS: The reasoned action approach was used, according to which the behavior of an individual is caused by behavioral intentions that are affected by (1) a persuasion that represents the individual's attitude toward the behavior, (2) perceived norms that describe the influence of other individuals, and (3) perceived norms that reflect the possibility of the individual influencing the behavior. RESULTS: The survey responses of 323 hospital visitors and 304 hospital employees were examined separately using SmartPLS 3.3.3. Bootstrapping procedures with 5000 subsamples were used to test the models (one-tailed test with a significance level of .05). The results show that attitude (ß=.536; P<.001; f²=.381) and perceived norms (ß=.236; P<.001; f²=.087) are predictors of hospital visitors' intention to use an IPS. In addition, attitude (ß=.283; P<.001; f²=.114), perceived norms (ß=.301; P<.001; f²=.126), and perceived behavioral control (ß=.178; P=.005; f²=.062) are predictors of hospital employees' intention to use an IPS. CONCLUSIONS: This study has two major implications: (1) our extended reasoned action approach model, which takes into account spatial abilities and personal innovativeness, is appropriate for determining hospital visitors' and employees' intention to use an IPS; and (2) hospitals should invest in implementing IPS with a focus on (a) navigational services for hospital visitors and (b) asset tracking for hospital employees.

Beliefs of women of childbearing age on healthy sleep habits: a reasoned action approach elicitation study.

There is little information on the determinants of healthy sleep habits (HSH) among women of childbearing age (WOCBA). The objective was to identify WOCBA's beliefs on HSH based on the Reasoned Action Approach. Thirty WOCBA (18-41 years) were randomly assigned to answer questions regarding one of three HSH: avoiding screen use in bed; avoiding caffeine, alcohol and cigarettes before bedtime; and having a regular bedtime and wake up time even on weekends. A content analysis was performed independently by two experts to identify the most important beliefs using a 75% cumulative frequency of mention. Participants reported that adopting the HSH would improve sleep, avoid side effects, help them relax before bedtime and make them feel like they were missing out on things. Adopting the HSH was associated with feeling relaxed and satisfied, but also qualified as unpleasant and abnormal. WOCBA mentioned their parents, partner, siblings and children would approve/disapprove if they adopted the HSH and were the most/least likely to adopt them. Barriers were having activities in the evening and social situations. Facilitating factors were putting their electronic devices away from bed, having alternatives and a regular schedule. These results can guide the development of interventions promoting HSH among WOCBA.

Application of health behaviour theory to sleep health improvement.

Although sleep hygiene is often used for broad sleep health promotion efforts, sleep hygiene education programmes are largely ineffective. These programmes are limited by their lack of a theoretical foundation. Health behaviour theory (HBT) has been used for decades to successfully predict and modify many health behaviours, but its use in the study of sleep health is rare. The purpose of this review is threefold. First, four dominant HBTs will be introduced. Second, the brief literature on HBT and sleep health will be reviewed. Lastly, a translational research agenda will be proposed. The present review concludes that HBT shows potential in both the prediction and modification of sleep health, and that there are several short- and long- term research goals to advance these efforts.

Beliefs Associated with Intention to Use PrEP Among Cisgender U.S. Women at Elevated HIV Risk.

Women comprise 19% of those newly diagnosed with HIV in the U.S. There is a wide gap between recommended use of pre-exposure prophylaxis (PrEP) and actual uptake among women who are eligible for PrEP. In order to identify women's beliefs and intentions about starting PrEP, a survey, informed by the reasoned action approach, was administered to 160 cisgender PrEP-eligible women, age 18-55, in Philadelphia and New York City. The mean age was 40.2 years (SD = 11.78), 44% had completed high school, 75% were unemployed, and 85% experienced financial instability in the past 3 months. Multivariate linear regression analyses identified sets of behavioral and normative beliefs associated with intention to start PrEP in the next 3 months. Behavioral beliefs reflected views about PrEP benefits such as preventing HIV, and normative beliefs reflected perceptions of support or lack thereof from others including partners, friends, mother, and children. These findings can be used to inform interventions to foster greater PrEP uptake among women.

Correlates of sugar-sweetened beverages consumption among adolescents.

OBJECTIVE: To identify correlates and underlying beliefs regarding the adolescents' intention to abstain from consuming sugar-sweetened beverages (SSB) and the consumption of ≤1 daily portion of SSB. DESIGN: Correlational study. SETTING: Region of Chaudière-Appalaches in the province of Quebec, Canada. PARTICIPANTS: 311 adolescents aged 13-18 years completed a self-administrated online questionnaire based on the Reasoned Action Approach. Frequency and quantity of different types of SSB within the past month were measured. RESULTS: Total mean SSB intake was 882·6 ml/d (654·0 kJ/d ). Only 11·3 % abstained from SSB within the last month. Intention to abstain from SSB was explained by identification as SSB abstainers (ß = 0·47), perceived norm (ß = 0·32), attitude (ß = 0·30), age 13-14 years (ß = -0·27) and perception of the school environment (ß = 0·14), which explained 66 % of the variance. Consumption of ≤1 daily portion of SSB was explained by the intention to abstain (OR = 1·55; 95 % CI 1·14, 2·11), perceived behavioural control to abstain (OR = 1·80; 95 % CI 1·29, 2·52), sex (girls v. boys: OR = 2·34; 95 % CI 1·37, 3·98) and socio-economic status (advantaged v. disadvantaged school: OR = 2·08; 95 % CI 1·21, 3·56). Underlying beliefs (i.e. more energy, decreased risk of addiction and friends' approval) associated with intention as well as perceived barriers (e.g. access to SSB, after an activity that makes you thirsty), and facilitating factors (e.g. access to water) linked to SSB consumption were identified. CONCLUSIONS: The results can inform public health interventions to decrease SSB consumption and their associated health problems among adolescents.

The Role of Attitudes, Social Norms, and Perceived Behavioral Control as Factors Influencing Urban and Suburban Residential Adoption of Stormwater Best Management Practices.

Nonpoint source pollution conveyed by stormwater in urban areas poses a significant threat to quality of waterbodies in the US. In the absence of systematic regulations on household stormwater management, municipalities rely largely on educational programs to encourage voluntary adoption of lawncare best management practices (BMPs) by residents who slow down and temporarily capture excess stormwater and filter out pollutants entering waterways. The current literature on factors influencing urban dwellers' adoption of lawncare BMPs mostly focuses on demographics, barriers to adoption, and effectiveness of education and outreach programs. This study applies the reasoned action approach (RAA) behavioral theory to investigate how the combination of individuals' attitudes, social norms, and perceived behavioral control may affect their decision to adopt three lawncare BMPs, including mulching and fertilizer/pesticide avoidance, and support a municipal ban on lawncare chemicals. We use survey data (n = 235) from residents in two neighboring cities in central Maine, USA. We found that perceived behavioral control predicted fertilizer/pesticide avoidance and mulching, and that beliefs and attitudes toward the outcomes of adopting lawncare BMPS were positively associated with mulching and support for a municipal ban on lawncare chemicals. We observed statistically significant but inconsistent associations between several independent variables-including descriptive and injunctive social norms, gender, level of education, age, and home ownership status-and our dependent variables of interest. The findings provide insights into an underexplored set of factors and confirmatory evidence for previously tested factors influencing urban residents' BMP adoption, and suggest new strategies and communication frames for environmental managers and researchers.

Explaining the intention of dental health personnel to report suspected child maltreatment using a reasoned action approach.

BACKGROUND: This study provides an empirical test of the reasoned action approach (RAA) socio-cognitive theory with the aim of 1) predicting the intention of public dental health personnel (PDHP) to report suspected child-maltreatment to child welfare services (CWS); 2) estimating the effects of the theoretical constructs of RAA, including experiential and instrumental attitudes, injunctive and descriptive norms, and perceived capacity and autonomy regarding PDHP's behavioural intentions; and 3) exploring whether the RAA operates equivalently (i.e., is invariant) in male and female providers. METHODS: This national cross-sectional study was conducted in Norway. An electronic survey was distributed to 1542 dentists and dental hygienists working in the public dental health service. The survey included RAA items constructed in accordance with the recommendations for the RAA model. Structural equation modelling (SEM) was used to identify factors derived from the theory of RAA to predict PDHP reporting intentions. RESULTS: A total of 77.8% (1200) of those surveyed responded to the survey. The present study provided support for the utility of the RAA across both male and female providers in predicting their intention to report suspected child-maltreatment to the CWS. The final modified SEM model revealed that instrumental attitudes and perceived behavioural control (based on merged capacity and autonomy parameters) were the strongest predictors of intention to report, followed by the reporting of descriptive norms, injunctive norms and experiential attitudes. These factors explained 63.6% of the observed variance in the reporting intention. CONCLUSIONS: The large amount of explained variance suggests that RAA is a well-functioning theory that predicts PDHP's reporting intentions to CWS across gender, and gives an understanding of the socio-cognitive factors involved. To strengthen reporting intention among dental personnel, this study suggests educators should focus on the value and positive consequences of reporting, the resources available and how to overcome obstacles; attention to normative expectations and individuals' feelings about reporting may also be helpful.

Differences in determinants of aerobic and muscle strengthening physical activity among college students: a reasoned action approach.

While there is a concerted effort to promote physical activity (PA) across United States government and non-governmental organizations, interventions typically focus on aerobic forms of PA, leaving out muscle strengthening PA. The purpose of this study was to operationalize the Reasoned Action Approach (RAA) to explain theory-based correlates of aerobic and muscle strengthening PA, which can provide targets for future public health interventions. Theory-based correlates of both PA behaviors were evaluated using logistic regression analyses, and intentions predicted a significant amount of aerobic PA (14.9%) and muscle strengthening PA (30.7%). Theory-based correlates of intentions to both PA behaviors were evaluated using linear regression analyses, and attitudes, perceived norms, and perceived behavioral control predicted a significant amount for aerobic PA (46.2% to 55.8%) and for muscle strengthening PA (53.9% to 59.8%). Finally, theory-based correlates of attitudes, injunctive norms, descriptive norms and perceived behavioral control were evaluated using salient beliefs, derived from an elicitation study. Results suggest that the RAA is a robust framework for predicting both types of PA behaviors. Belief-based measures also provides guidance for future public health promotion interventions and health communication strategies.
