Investigating the predictive validity of implicit and explicit measures of motivation on condom use, physical activity and healthy eating

You don't know why you (don't) exercise: The relationship between automatic processes and physical activity (or sedentary behavior): A meta-analysis

OBJECTIVES

This meta-analysis aimed to examine the relationship between automatic processes and behavior as well as their moderators.

METHODS

There were 126 effect sizes (Fisher's Z) extracted from 55 independent research studies involving 10,432 participants. Meta-analyses were conducted using Comprehensive Meta-Analysis Version 3.3. Univariate meta-regression models were used to analyze underlying moderators.

RESULTS

Meta-analysis after correction found that automatic processes could significantly and positively predict behavior, but the effect size was small (Fisher's Z = 0.057, p < 0.001, 95% CI [0.043, 0.070]).

CONCLUSIONS

Different components of automatic processes, task reliability, and study design moderated the relationship between automatic processes and behavior. Future research could explore automatic measures at a neurophysiological level or use population-matched stimuli for specific populations to improve measure validity. In addition, future research should accumulate evidence on how to reduce sedentary behavior.

The Body Image Virtual Reality Assessment (BIVRA): Measuring the body representation through virtual reality

Our physical and psychological well-being is significantly influenced by how we perceive our body, in addition to our thoughts and emotions associated with it. Dysfunctional body perceptions and attitudes play a key role in the development and maintenance of severe conditions such as eating disorders in both males and females. Given its relevance, some attempts have been made to improve body image assessment methods in terms of perceptual accuracy and body satisfaction taking advantage of technological advances such as virtual reality. However, existing applications have mainly focused on women and clinical conditions. In this study, we presented the Body Image Virtual Reality Assessment (BIVRA), a virtual reality figure rating scale to assess body image in both male and female subjects. We tested BIVRA's ability to measure perceptual accuracy and compared its results with a standardized body satisfaction questionnaire. Additionally, we investigated gender differences. BIVRA was found to be effective in assessing body image. We observed that a perceptually based task successfully captured both low and high levels of body representations, shedding light on the significant gender differences. The association between BIVRA and the body satisfaction questionnaires was moderated by gender, with a stronger association for women. While further validation of BIVRA is needed to fully exploit its potential, our results suggest that the integration of virtual reality into the assessment of body image and related disorders may significantly enhance our understanding of individuals struggling with body image issues and has the potential to advance current methods and techniques.

Emotional Intelligence, Academic Motivation, and Achievement among Health Science Students in Saudi Arabia: A Self-Deterministic Approach

PURPOSE

This study used a self-deterministic approach to explore the relationship between emotional intelligence (EI), academic motivation (AM), and achievement among health science students.

METHODS

A descriptive cross-sectional study was conducted in three cities of Saudi Arabia (Dammam, Riyadh, and Jeddah). A convenience sample of 450 students was incorporated using the multistage cluster sampling technique. The online survey contained three sections: students' basic data and academic achievement level, the modified Schutte self-report inventory, and the Academic Motivation Scale lowercase.

RESULTS

This study revealed moderate overall scores for EI (57.1%), AM (55.6%), and grade point average (GPA) (57.6%). The overall EI score, its domains, and GPA had significant positive correlations with overall AM and intrinsic and extrinsic motivation (p < .01). Amotivation had an insignificant correlation with GPA (p < .05), but it was negatively correlated with EI and its domains (p < .01). Multiple regression analysis proved that EI domains predicted 5.0% of GPA variance; emotions appraisal and expression (β = .02, p = .024), regulation (β = .11, p = .032), and utilization (β = .24, p < .01). EI domains also predicted 26.0% of AM variance; emotions appraisal and expression (β = .11, p = .04), regulation (β = .33, p < .01), and utilization (β = .23, p <.01). Moreover, AM predicted 4.0% of the variance in GPA; intrinsic (β = .25, p = .004) and extrinsic (β = .11, p = .022) motivation. AM also predicted 25.0% of the variance in EI: intrinsic (β = .34, p < .01) and extrinsic motivation (β = .26, p = .026).

CONCLUSION

EI and AM have a bidirectional influence on each other, significantly shaping the GPA of health sciences students in Saudi Arabia, where intrinsic motivation has a predominant role. Thus, promoting students' AM and EI is recommended to foster their academic achievement.

Investigating the role of morningness/eveningness in physical activity engagement

Objective

Despite being aware of the positive health-related outcomes of physical activity, many people remain inactive. The aim of this study is to apply a combination of constructs from the health action process approach and self-determination theory, as well as habit and morningness/eveningness, to predict physical activity engagement.

Methods

A prospective design was used to collect data from 136 participants (16–64 years old), at two-time points, one week apart. The sample consisted of 99 women, 36 men and 1 individual who identified as non-binary. Participants preferred time-of-day was measured using the Morningness-Eveningness Stability Scale (MESSi), while physical activity engagement was measured using the International Physical Activity Questionnaire (short-version). Two hierarchical, multiple regressions were conducted, to predict motivation to engage and to directly predict physical activity engagement. Furthermore, a mediation analysis was conducted to determine the effect of planning on physical activity engagement.

Results

Results showed that younger individuals and those with greater self-efficacy were more motivated to engage while planning directly predicted physical activity engagement. However, morningness/eveningness did not significantly predict engagement. Additionally, planning was found to mediate the motivation-engagement relationship.

Conclusion

This study demonstrates how planning influences individuals’ physical activity engagement, as well as the role self-efficacy and age play in their motivation to engage. Even though morningness/eveningness was not an important predictor, behaviour change techniques related to action planning and the use of multi-component approaches to behaviour change, could be used in interventions focused on increasing individuals’ physical activity engagement.

Social cognition theories and behavior change in COVID-19: A conceptual review

The COVID-19 pandemic has had unprecedented health, economic, and social consequences worldwide. Although contact reductions and wearing face coverings have reduced infection rates, and vaccines have reduced illness severity, emergence of new variants of the coronavirus that causes COVID-19, and the shift from pandemic to endemic patterns of infection, highlights the importance of ongoing preventive behavior adherence to manage future outbreaks. Research applying social cognition theories may assist in explaining variance in these behaviors and inform the development of efficacious behavior change interventions to promote adherence. In the present article, we summarize research applying these theories to identify modifiable determinants of COVID-19 preventive behaviors and the mechanisms involved, and their utility in informing interventions. We identify limitations of these applications (e.g., overreliance on correlational data, lack of long-term behavioral follow-up), and suggest how they can be addressed. We demonstrate the virtue of augmenting theories with additional constructs (e.g., moral norms, anticipated regret) and processes (e.g., multiple action phases, automatic processes) to provide comprehensive, parsimonious behavioral explanations. We also outline how the theories contribute to testing mechanisms of action of behavioral interventions. Finally, we recommend future studies applying these theories to inform and test interventions to promote COVID-19 preventive behavior adherence.

Predicting COVID-19 booster vaccine intentions

Achieving broad immunity through vaccination is a cornerstone strategy for long‐term management of COVID‐19 infections, particularly the prevention of serious cases and hospitalizations. Evidence that vaccine‐induced immunity wanes over time points to the need for COVID‐19 booster vaccines, and maximum compliance is required to maintain population‐level immunity. Little is known of the correlates of intentions to receive booster vaccines among previously vaccinated individuals. The present study applied an integrated model to examine effects of beliefs from multiple social cognition theories alongside sets of generalized, stable beliefs on individuals' booster vaccine intentions. US residents (N = 479) recruited from an online survey panel completed measures of social cognition constructs (attitude, subjective norms, perceived behavioral control, and risk perceptions), generalized beliefs (vaccine hesitancy, political orientation, and free will beliefs), and COVID‐19 vaccine intentions. Social cognition constructs were related to booster vaccine intentions, with attitude and subjective norms exhibiting the largest effects. Effects of vaccine hesitancy, political orientation, and free will beliefs on intentions were mediated by the social cognition constructs, and only vaccine hesitancy had a small residual effect on intentions. Findings provide preliminary evidence that contributes to an evidence base of potential targets for intervention messages aimed at promoting booster vaccine intentions.

Predicting school students' physical activity intentions in leisure-time and school recess contexts: Testing an integrated model based on self-determination theory and theory of planned behavior

Background

Identifying psychological correlates of children’s physical activity intentions may signpost potentially modifiable targets for interventions aimed at promoting physical activity participation. School recess and leisure-time outside of school are appropriate contexts in which such interventions may be delivered. However, few studies have identified correlates of physical activity intentions in these environments. Examining correlates in these contexts may provide formative evidence on which to base interventions to promote physical activity.

Purpose

The current study adopted an integrated theoretical model to test relations between motivational constructs from self-determination theory, social cognition constructs from the theory of planned behavior, and physical activity intentions in leisure-time and school recess contexts.

Methods

Finnish school children (N = 845, M age = 13.93, SD = 0.99) from three lower-secondary schools completed self-report measures of perceived autonomy support by peers, autonomous and controlled motivation, attitudes, subjective norms, perceived behavioral control, and physical activity intentions for both contexts.

Results

Well-fitting structural equation models controlling for past behavior indicated that autonomous motivation in the school recess context and attitude in both contexts were the most pervasive predictors of physical activity intentions, and mediated the relationship between perceived autonomy support and intentions. Multi-group analyses supported invariance of the models in both contexts across gender, grades, and school, with few variations.

Conclusions

The current study supports relations between motivational and social cognition correlates of children’s physical activity intentions in school recess and leisure-time contexts. Future research should extend these findings to the prediction of follow-up participation in physical activity.

General causality orientations in self-determination theory: Meta-analysis and test of a process model

Causality orientations theory, a key sub-theory of self-determination theory, identifies three distinct causality orientations: autonomy, control, and impersonal orientation. The theory proposes generalized effects of the orientations on motivation and behavior. We meta-analyzed studies ( k = 83) testing relations between causality orientations, forms of motivation from self-determination theory, and behavior. Pooled data were used to test a process model in which autonomous and controlled forms of motivation mediated relations between causality orientations and behavior. Results revealed that autonomy and control orientations were positively correlated with autonomous and controlled forms of motivation, respectively. Impersonal orientation was correlated negatively with autonomy orientation and autonomous forms of motivation, and positively with control orientation and controlled forms of motivation. Process model tests revealed total effects of autonomy orientation on behavior, comprising direct and indirect effects through autonomous motivation, and a positive direct effect of control orientation on behavior and a negative indirect effect through controlled motivation, resulting in a zero total effect. Analysis of age, gender, behavior type, study design, and study quality revealed few moderator effects on model relations. Findings support effects of autonomy orientation on motivation and behavior, and the processes involved, and identify constructs that could be targeted, or circumvented, in behavioral interventions.

Predicting limiting 'free sugar' consumption using an integrated model of health behavior

Excess intake of 'free sugars' is a key predictor of chronic disease, obesity, and dental ill health. Given the importance of determining modifiable predictors of free sugar-related dietary behaviors, we applied the integrated behavior change model to predict free sugar limiting behaviors. The model includes constructs representing 'reasoned' or deliberative processes that lead to action (e.g., social cognition constructs, intentions), and constructs representing 'non-conscious' or implicit processes (e.g., implicit attitudes, behavioral automaticity) as predictors of behavior. Undergraduate students (N = 205) completed measures of autonomous and controlled motivation, the theory of planned behavior (TPB) measures of explicit attitude, subjective norms, perceived behavioral control (PBC), and intentions, past behavior, implicit attitude, and behavioral automaticity at an initial point in time, and free sugar limiting behavior and behavioral automaticity two weeks later. A Bayesian structural equation model indicated that explicit attitude, subjective norms, and PBC predicted behavior via intention. Autonomous motivation predicted behavior indirectly through all TPB variables, while controlled motivation predicted behavior only via subjective norms. Implicit attitudes and behavioral automaticity predicted behavior directly and independently. Past behavior predicted behavior directly and indirectly through behavioral automaticity and intentions, but not implicit attitudes. Current findings suggest pervasive effects of constructs representing both reasoned and non-conscious processes and signpost potential targets for behavioral interventions aimed at minimizing free sugar consumption.

'I can do this': a qualitative exploration of acceptability and experiences of a physical activity behaviour change intervention in people with multiple sclerosis in the UK

OBJECTIVES

The purpose of this study was to explore the experiences of people with multiple sclerosis (MS) who participated in iStep-MS, a feasibility randomised controlled trial of a behaviour change intervention that aimed to increase physical activity and reduce sedentary behaviour.

DESIGN

A qualitative approach was undertaken embedded in the feasibility randomised controlled trial. One-to-one semi-structured interviews were conducted and analysed using Framework analysis.

SETTING

Participants were recruited from a single MS therapy centre in the southeast of England, UK.

PARTICIPANTS

Sixty people with MS were randomly allocated in a 1:1 ratio to the intervention or usual care. Following a purposive sampling strategy, 15 participants from the intervention arm undertook 1:1 semi-structured interviews.

INTERVENTIONS

The iStep-MS intervention consisted of four therapist-led sessions over 12 weeks, supported by a handbook and pedometer.

RESULTS

Three themes were identified from the data. "I can do this": developing competence in physical activity highlights the enhanced physical activity confidence gained through goal setting and accomplishment. "I felt valued": the nurturing culture provides an overview of the supportive and non-judgemental environment created by the programme structure and therapeutic relationship. Finally, "What can I do?": empowered enactment describes the transition from the supported iStep-MS intervention to intrinsically motivated physical activity enactment.

CONCLUSIONS

Overall, this study supports the acceptability of the iStep-MS intervention and identified key areas that supported participants to be physically active.

Can Serious Games Assess Decision-Making Biases?

Abstract. The limitations of self-report questionnaires and interview methods for assessing individual differences in human cognitive biases have become increasingly apparent. These limitations have led to a renewed interest in alternative modes of assessment, including for implicit and explicit aspects of human behavior (i.e., dual-process theory). Acknowledging this, the present study was conducted to develop and validate a serious game, “Don Quixote,” for measuring specific cognitive biases: the bandwagon effect and optimism bias. We hypothesized that the implicit and explicit game data would mirror the results from an interview and questionnaire, respectively. To examine this hypothesis, participants ( n = 135) played the serious game and completed a questionnaire and interview in a random order for cross-validation. The results demonstrated that the implicit game data (e.g., response time) were highly correlated with the interview data. On the contrary, the explicit game data (e.g., game score) were comparable to the results from the questionnaire. These findings suggest that the serious game and the underlying intrinsic nature of its game mechanics (i.e., evoking instant responses under time pressure) are of importance for the further development of cognitive bias measures in both academia and practice.

Influence of Emotional Intelligence, Motivation and Resilience on Academic Performance and the Adoption of Healthy Lifestyle Habits among Adolescents

Included among the basic objectives of Physical Education (PE) classes is the consolidation of habits of a healthy lifestyle among adolescents. However, the main studies in this field have focused on cognitive aspects related to students during these classes, yet they ignore the role that emotions can play in the adoption of future habits. Objectives: To analyze how emotions (emotional intelligence and emotional state) can influence the resilience and motivation of adolescents, as well as academic performance and adoption of healthy lifestyle habits. Methodology: 615 secondary school students between the ages of 14 and 19 participated (M = 16.02; SD = 1.57) in the study. A structural equations model was developed using the main variables and by applying some of the principles of Self-Determination Theory. The results show that emotional intelligence is positively related to positive emotions and negatively related to negative emotions. Positive emotions positively predict both self-motivation towards physical education classes and resilience. Resilience positively predicts self-motivation. Finally, self-motivation acts as a predictor of both academic performance and regular participation in physical activity. Conclusions: This study successfully shows the importance of focusing on emotions in PE classes inasmuch as emotion increases the tendency to get good grades and maintain active lifestyle habits. In this sense, focusing on the emotions of students in PE could prove quite beneficial.

"They didn't give up on me": a women's transitions clinic from the perspective of re-entering women

BACKGROUND

Women recently released from incarceration have increased rates of co-occurring substance use, physical health, and mental health disorders. During re-entry, they face challenges navigating needed health services and social services stemming from these problems. Women's Initiative Supporting Health Transitions Clinic (WISH-TC) is a primary care program that facilitates treatment access for re-entering women. Strategies include support and navigation assistance from peer community health workers.

METHODS

Thirteen participants, of whom 11 had a substance use disorder, completed semi-structured interviews about their experiences in WISH-TC as part of a process evaluation. We conducted a qualitative framework analysis informed by self-determination theory.

RESULTS

WISH-TC supported autonomy as staff helped motivate women to work toward personal health goals. Women were empowered to have their health needs met, and consequently, prioritized attending clinic. Regarding competence, WISH-TC built upon women's existing knowledge to increase their health literacy and better understand their individual health needs. Relatedness support, both prior to re-entry and ongoing with clinic staff, was key in women's satisfaction with their care. The clinic made procedural changes in response to the interviews, including providing orientation for the patients and training the clinic in trauma-informed practices.

CONCLUSIONS

Our findings highlight the potential of a program for re-entering women, including those with substance use disorders to strengthen their abilities to navigate complex healthcare and societal systems. WISH-TC helped women feel supported, motivated, and competent to address their substance use, physical, and mental health conditions.

Implicit process interventions in eating behaviour: a meta-analysis examining mediators and moderators

Dual-process models integrate deliberative and impulsive mental systems and predict dietary behaviours better than deliberative processes alone. Computerised tasks such as the Go/No-Go, Stop-Signal, Approach-Avoidance, and Evaluative Conditioning have been used as interventions to directly alter implicit biases. This meta-analysis examines the effects of these tasks on dietary behaviours, explores potential moderators of effectiveness, and examines implicit bias change as a proposed mechanism. Thirty randomised controlled trials testing implicit bias interventions (47 comparisons) were included in a random-effects meta-analysis, which indicated small cumulative effects on eating-related behavioural outcomes (g = -0.17, CI₉₅ = [-0.29; -0.05], p = .01) and implicit biases (g = -0.18, CI₉₅= [-0.34; -0.02], p = .02). Task type moderated these effects, with Go/No-Go tasks producing larger effects than other tasks. Effects of interventions on implicit biases were positively related to effects on eating behaviour (B = 0.42, CI₉₅= [0.02; 0.81], p = .03). Go/No-Go tasks seem to have most potential for altering dietary behaviours through implicit processes. While changes in implicit biases seem related to the effects of these interventions on dietary outcomes, more research should explore whether repeated exposure to implicit bias interventions may have any practical intervention value in real world settings.

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

BACKGROUND

This 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.

METHODS

Data 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.

RESULTS

Path 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.

CONCLUSIONS

Results 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.

Does a Primary Health Clinic for Formerly Incarcerated Women Increase Linkage to Care?

OBJECTIVE

This study examined a primary care-based program to address the health needs of women recently released from incarceration by facilitating access to primary medical, mental health, and substance use disorder (SUD) treatment.

STUDY DESIGN

Peer community health workers recruited women released from incarceration within the past 9 months into the Women's Initiative Supporting Health Transitions Clinic (WISH-TC). Located within an urban academic medical center, WISH-TC uses cultural, gender, and trauma-specific strategies grounded in the self-determination theory of motivation. Data abstracted from intake forms and medical charts were examined using bivariate and multivariable regression analyses.

RESULTS

Of the 200 women recruited, 100 attended the program at least once. Most (83.0%) did not have a primary care provider before enrollment. Conditions more prevalent than in the general population included psychiatric disorders (94.0%), substance use (90.0%), intimate partner violence (66.0%), chronic pain (66.0%), and hepatitis C infection (12.0%). Patients received screening and vaccinations (65.9%-87.0%), mental health treatment (91.5%), and SUD treatment (64.0%). Logistic regression revealed that receipt of mental health treatment was associated with number of psychiatric (adjusted odds ratio [AOR], = 4.09; p < .01), and social/behavioral problems (AOR, 2.67; p = .04), and higher median income (AOR, 1.07; p = .05); African American race predicted lower receipt of SUD treatment (AOR, 0.08; p < .01).

CONCLUSIONS

An innovative primary care transitions program successfully helped women recently released from incarceration to receive medical, mental health, and SUD treatment. Primary care settings with specialty programs, including community health workers, may provide a venue to screen, assess, and help recently incarcerated women access needed care.

The role of habit in different phases of exercise

OBJECTIVES

The primary purpose of this study was to investigate how habit strength in a preparatory and performance phase predicts exercise while accounting for intention. The secondary purpose was to determine the strength of potential habit antecedents (affective judgement, perceived behavioural control, consistency, and cues) in both exercise phases.

DESIGN

This was a prospective study with measures collected at baseline and week 6.

METHODS

Participants (n = 181) were a sample of adults (18-65) recruited across nine gyms and recreation centres who completed baseline and follow-up questionnaires after 6 weeks.

RESULTS

Intention (β = .28, p = .00) and habit preparation (β = .20, p = .03), predicted exercise, and change of exercise with coefficients of β = .25, (p = .00) and β = .18, (p = .04), respectively, across 6 weeks but not habit performance (p>.05).

CONCLUSIONS

This study highlighted the distinction between the two phases of exercise and the importance of preparatory habit in predicting behaviour. Focusing on a consistent preparatory routine could be helpful in establishing an exercise habit. Statement of contribution What is already known on this subject? A recent meta-analysis found habit to correlate r = .43 with behaviour (Gardner, de Bruijn, & Lally, ). Verplanken and Melkevik () propose that habit in exercise should be measured in separate components. Phillips and Gardner () interpreted this as habitual instigation (thought) to exercise and execution. What does this study add? Extended pervious work and identified two distinct behavioural phases (preparation and performance) for exercise. Habit model revealed that temporal consistency was the strongest predictor in both phases of exercise. Intention and habit of preparatory behaviour predicted exercise fluctuations in gym members.

Applying the Integrated Behavior Change Model to Understanding Physical Activity Among Older Adults: A Qualitative Study

We explored older adults' experiences of physical activity (PA) and related decision-making processes underlying PA. Twenty Australians (M_age = 73.8 years) participated in semistructured interviews. Data were analyzed using thematic analysis, and identified themes were matched deductively within motivational, volitional, and implicit processes of the integrated behavior change model for PA. Motivational influences such as participants' time orientation toward health and perceptions of what PA should be like were frequently featured in participants' narratives. Volitional processes were also identified, with participants reporting different ways of coping with competing priorities. Physical surroundings and habitual PA were the identified themes within implicit processes. Together, these findings contribute to a better understanding of subjective experiences of older adults regarding PA. They also add to a more contextual understanding of multiple decision-making processes underpinning older adults' PA engagement. Identified concepts may be used in future research and PA interventions targeting older adults.

The Effect of Men's Body Attitudes and Motivation for Gym Attendance

Caudwell, KM and Keatley, DA. The effect of men's body attitudes and motivation for gym attendance. J Strength Cond Res 30(9): 2550-2556, 2016-The current study integrates men's body attitudes with implicitly and explicitly measured motivation to investigate the role of these factors in predicting gym attendance. Male participants (N = 99) who regularly attended a gym were recruited to participate in an online questionnaire. Participants completed implicit and explicit measures of motivation, explicitly measured men's body attitudes, and reported the average number of gym visits per week. Attitudes related to body fat and explicitly measured autonomous motivation significantly predicted typical gym attendance. Implicitly measured motivation significantly and negatively predicted gym attendance. Results indicate some support for a dual-systems account of gym attendance. Men's body attitudes and autonomous motivation influences gym attendance; however, implicitly measured motivation showed antagonistic effects. Although individuals may explicitly state their autonomous motivation for gym attendance, attendance may also be influenced at the explicit level. Health and fitness professionals may improve gym attendance by focusing on people's reasons for attending a gym, facilitating autonomous motivation in clients, and minimizing the influence of controlled reasons for exercise.

A longitudinal investigation of older adults' physical activity: Testing an integrated dual-process model

OBJECTIVE

To assess the effects of conscious and non-conscious processes for prediction of older adults' physical activity (PA), we tested a dual-process model that integrated motivational (behavioural intention) and volitional (action planning and coping planning) processes with non-conscious, automatic processes (habit).

METHOD

Participants (N = 215) comprised community-dwelling older adults (M = 73.8 years). A longitudinal design was adopted to investigate direct and indirect effects of intentions, habit strength (Time 1), and action planning and coping planning (Time 2) on PA behaviour (Time 3). Structural equation modelling was used to evaluate the model.

RESULTS

The model provided a good fit to the data, accounting for 44% of the variance in PA behaviour at Time 3. PA was predicted by intentions, action planning, and habit strength, with action planning mediating the intention-behaviour relationship. An effect of sex was also found where males used fewer planning strategies and engaged in more PA than females.

CONCLUSIONS

By investigating an integration of conscious and non-conscious processes, this study provides a novel understanding of older adults' PA. Interventions aiming to promote PA behaviour of older adults should target the combination of psychological processes.

Effects of pretesting implicit self-determined motivation on behavioral engagement: evidence for the mere measurement effect at the implicit level

Research into individuals’ intended behavior and performance has traditionally adopted explicitly measured, self-report constructs, and outcomes. More recently, research has shown that completing explicit self-report measures of constructs may effect subsequent behavior, termed the “mere measurement” effect. The aim of the present experiment was to investigate whether implicit measures of motivation showed a similar mere measurement effect on subsequent behavior. It may be the case that measuring the implicit systems affects subsequent implicit interventions (e.g., priming), observable on subsequent behavior. Priming manipulations were also given to participants in order to investigate the interaction between measurement and priming of motivation. Initially, a 2 [implicit association test (IAT: present vs. absent) ×2 (Prime: autonomous vs. absent) and a 2 (IAT: present vs. absent) × 2 (Prime: controlled vs. absent)] between participants designs were conducted, these were them combined into a 2 (IAT: present vs. absent) ×3 (Prime: autonomous vs. controlled vs. absent) between participants design, with attempts at a novel task taken as the outcome measure. Implicit measure completion significantly decreased behavioral engagement. Priming autonomous motivation significantly facilitated, and controlled motivation significantly inhibited performance. Finally, there was a significant implicit measurement × priming interaction, such that priming autonomous motivation only improved performance in the absence of the implicit measure. Overall, this research provides an insight into the effects of implicit measurement and priming of motivation and the combined effect of completing both tasks on behavior.

Autonomous and controlled motivational regulations for multiple health-related behaviors: between- and within-participants analyses

Self-determination theory has been applied to the prediction of a number of health-related behaviors with self-determined or autonomous forms of motivation generally more effective in predicting health behavior than non-self-determined or controlled forms. Research has been confined to examining the motivational predictors in single health behaviors rather than comparing effects across multiple behaviors. The present study addressed this gap in the literature by testing the relative contribution of autonomous and controlling motivation to the prediction of a large number of health-related behaviors, and examining individual differences in self-determined motivation as a moderator of the effects of autonomous and controlling motivation on health behavior. Participants were undergraduate students (N = 140) who completed measures of autonomous and controlled motivational regulations and behavioral intention for 20 health-related behaviors at an initial occasion with follow-up behavioral measures taken four weeks later. Path analysis was used to test a process model for each behavior in which motivational regulations predicted behavior mediated by intentions. Some minor idiosyncratic findings aside, between-participants analyses revealed significant effects for autonomous motivational regulations on intentions and behavior across the 20 behaviors. Effects for controlled motivation on intentions and behavior were relatively modest by comparison. Intentions mediated the effect of autonomous motivation on behavior. Within-participants analyses were used to segregate the sample into individuals who based their intentions on autonomous motivation (autonomy-oriented) and controlled motivation (control-oriented). Replicating the between-participants path analyses for the process model in the autonomy- and control-oriented samples did not alter the relative effects of the motivational orientations on intention and behavior. Results provide evidence for consistent effects of autonomous motivation on intentions and behavior across multiple health-related behaviors with little evidence of moderation by individual differences. Findings have implications for the generalizability of proposed effects in self-determination theory and intentions as a mediator of distal motivational factors on health-related behavior.

Implementation intention and action planning interventions in health contexts: state of the research and proposals for the way forward

The purpose of this paper is to provide an overview of the literature on two planning intervention techniques in health behaviour research, implementation intentions and action planning, and to develop evidence-based recommendations for effective future interventions and highlight priority areas for future research. We focused our review on four key areas: (1) definition and conceptualisation; (2) format and measurement; (3) mechanisms and processes; and (4) design issues. Overall, evidence supports the effectiveness of planning interventions in health behaviour with advantages including low cost and response burden. There is, however, considerable heterogeneity in the effects across studies and relatively few registered randomised trials that include objective behavioural measures. Optimally effective planning interventions should adopt "if-then" plans, account for salient and relevant cues, include examples of cues, be guided rather than user-defined, and include boosters. Future studies should adopt randomised controlled designs, report study protocols, include fidelity checks and relevant comparison groups, and adopt long-term behavioural follow-up measures. Priority areas for future research include the identification of the moderators and mediators of planning intervention effects. Future research also needs to adopt "best practice" components of planning interventions more consistently to elucidate the mechanisms and processes involved.

Myopia prevention, near work, and visual acuity of college students: integrating the theory of planned behavior and self-determination theory

There has been little research examining the psychological antecedents of safety-oriented behavior aimed at reducing myopia risk. This study utilizes self-determination theory (SDT) and the theory of planned behavior (TPB) to understand the role of motivational and social-cognitive factors on individuals' near-work behavior. Adopting a prospective design, undergraduate students (n = 107) completed an initial questionnaire based on SDT in week 1, a second questionnaire containing measures of TPB variables in week 2, and objective measures of reading distance and visual acuity in week 6. The data were analyzed by variance-based structural equation modeling. The results showed that perceived autonomy support and autonomous motivation from SDT significantly predicted attitude, subjective norm, and perceived behavioral control from the TPB. These social-cognitive factors were significantly associated with intention and intention significantly predicted reading distance. The relationships in the model held when controlling for visual acuity. In conclusion, the integrated model of SDT and the TPB may help explain myopia-preventive behaviors.
