The relation between risk perceptions and physical activity among older adults: a prospective study

Past studies have found that risk perceptions of suffering from diseases play an important role in the development of intentions to perform physical activity (PA). According to the behaviour motivation hypothesis, perceived risk could be positively and directly related to PA, but this possibility has been ignored and/or underestimated. Accounting for recent methodological developments on the importance of study design and risk perception assessment, the purpose of the present study was to examine the risk-perceptions-PA relationship among older adults. Participants (N=143) aged from 61 to 70 years initially underwent measurement of risk perceptions, baseline PA, socio-demographic and health factors. Six months later, they were asked about their PA participation. Multiple regression analyses revealed that perceived risk of suffering from diseases and conditions without regular PA participation was an independent positive predictor of later PA, over and beyond baseline behaviour, socio-demographic and health variables. This study fills a gap in the existing literature on the PAs of older adults and reveals that risk perceptions are directly linked to their participation. In addition, it extends existing knowledge in health psychology on the behaviour motivation hypothesis, and emphasises the necessity of methodological adjustments when assessing the risk-perception-behaviour relationship.     

Comparative risk and perceived control: implications for psychological and physical well-being among older adults

As older adults become more susceptible to certain health crises, their preoccupation with their risk of suffering such events increases. Understanding the implications of risk perceptions is critical because they may have consequences for psychological and physical well-being in later life. In the present study of older adults living in the community, the authors examined participants' comparative risk estimates (CREs)--their perceptions of their own risk relative to a similar other's risk--of suffering a hip fracture. Using multiple regression analyses, the authors examined the role of CREs on psychological well-being (negative emotions, life satisfaction) and self-rated physical well-being (general physical health, recent physical health). The authors expected perceived control (PC) to moderate the relationship between CREs and well-being. The predicted interaction did occur: Among individuals with high PC, comparative optimism (perceiving a comparatively low risk) was associated with better psychological well-being (fewer negative emotions and greater life satisfaction) and better physical well-being (general and recent physical health) relative to comparative pessimism (perceiving a comparatively high risk). Among individuals with low PC, there were no differences in well-being between comparative optimists and comparative pessimists. These findings suggest that the protective effect of comparative optimism on well-being is limited to older adults who have a strong sense of control.     

Change in physical and psychological health over time in patients with cardiovascular disease: on the benefits of being self-determined,physically active,and eating well

This study tested a longitudinal model examining the roles of motivation and perceived competence in the prediction of physical activity (PA) and healthy eating (HE) in individuals with cardiovascular diseases, and the effects of adopting these behaviors on individuals’ health. Participants completed measures of global motivation (baseline), contextual motivation and perceived competence for PA and HE (3 months), and self-reports of PA and HE behaviors (6 months). Physiological indicators and life satisfaction were assessed at the baseline and at 12 months. Structural equation modeling supported that individuals with self-determined motivation (SDM) were more likely to feel competent in changing their lifestyle and to engage in moderate and strenuous (vs. mild) exercise and HE behaviors, which had beneficial effects on individuals’ physiological and psychological health. This research confirms the respective roles of SDM and perceived competence in the health behavior change process and emphasizes the key function of SDM in the adherence of healthy behaviors over time.     

A self-determination process model of physical activity adoption in the context of a randomized controlled trial

Objective: The PA Counseling (PAC) trial tested a primary care intervention using Self-Determination Theory (SDT) as the guiding framework. This paper presents specific results related to SDT constructs in a physical activity (PA) context. Specifically, whether patients who received both brief autonomy supportive PA counseling from their health-care provider and intensive (3 month) autonomy supportive counseling from a PA counselor would report greater levels of autonomy support, autonomous motivation, perceived competence and PA adoption, than patients receiving only brief counseling. In addition, we tested Williams’ SDT process model in the context of PA adoption.Method: Measures of autonomous motivation and perceived competence for PA were measured at baseline and 6 weeks. PA was assessed at baseline and 13 weeks. An autonomy support index was calculated by multiplying minutes of counseling by perceptions of autonomy support. Group differences in autonomy support, autonomous motivation, perceived competence and PA were examined. The SDT process model of PA adoption was tested via path analysis.Results: The results showed higher autonomy support and autonomous motivation at 6 weeks and higher PA levels at 13 weeks for the experimental group. The SDT process model for PA adoption showed that autonomous motivation and perceived competence at 6 weeks significantly predicted 13-week PA for the experimental group.Conclusions: This study provides a rigorous field test of SDT theory in a PA context. It demonstrates the versatility and applicability of the SDT model for health behavior change. SDT-trained PA counselors appear to provide valuable contribution to facilitating patient behavior change, by increasing patient autonomous motivation for PA.     

Predicting change in middle school students’ leisure-time physical activity participation: A prospective test of the trans-contextual model

We applied the trans-contextual model (TCM) to examine the effects of middle school students’ perceived autonomy support from their physical education (PE) teachers on autonomous motivation toward PE in school and, critically, autonomous motivation toward, and actual participation in, leisure-time physical activity (PA). The research adopted a three-wave prospective design enabling the modeling of change in the TCM constructs over time. Middle school students (N = 248) aged from 12 to 16 years reported their perceived autonomy support, autonomous motivation in PE, autonomous motivation toward leisure-time PA, attitudes, subjective norms, perceived behavioral control (PBC), intentions for PA in leisure-time, and leisure-time PA participation. The psychological constructs and leisure-time PA were measured at baseline (T0) and at a first follow-up occasion (T1) 5 weeks later. Another measure of PA was taken at a second follow-up occasion (T2) a further 5 weeks later. A single-indicator structural equation model using residualized change scores revealed that perceived autonomy support predicted autonomous motivation in PE (β = .345), and autonomous motivation in PE predicted autonomous motivation for leisure-time PA (β = .484). Autonomous motivation toward leisure-time PA predicted attitudes (β = .425), subjective norms (β = .264), and PBC (β = .517). Autonomous motivation toward leisure-time PA (β = .376), attitude (β = .231), and subjective norms (β = .185) predicted intentions toward leisure-time PA, and intentions predicted PA (β = .198). Findings extend research on the TCM by demonstrating its efficacy in predicting change in middle school students’ autonomous motivation across PE and leisure-time contexts, and accounting for change in intentions toward, and actual participation in, leisure-time PA.     

Older adults’ perceptions of ageing and their health and functioning: a systematic review of observational studies

Many older people perceive ageing negatively, describing it in terms of poor or declining health and functioning. These perceptions may be related to older adults’ health. The aim of this review was to synthesise existing research on the relationship between older adults’ perceptions of ageing and their health and functioning. A systematic search was conducted of five electronic databases (ASSIA, CINAHL, IBSS, MEDLINE and PsycINFO). Citations within identified reports were also searched. Observational studies were included if they included perceptions of ageing and health-related measures involving participants aged 60 years and older. Study selection, data extraction and quality appraisal were conducted using predefined criteria. Twenty-eight reports met the criteria for inclusion. Older adults’ perceptions of ageing were assessed with a variety of measures. Perceptions were related to health and functioning across seven health domains: memory and cognitive performance, physical and physiological performance, medical conditions and outcomes, disability, care-seeking, self-rated health, quality of life and death. How ageing is perceived by older adults is related to their health and functioning in multiple domains. However, higher quality and longitudinal studies are needed to further investigate this relationship.     

Self‐Favoring Bias for Physical Activity in Middle‐Aged and Older Adults1

A self‐favoring bias for physical activity (PA) was examined in a community‐based sample of middle‐aged and older adults (N= 3,211). Participants' actual level of PA relative to peers was compared with their perceived PA relative to peers. It was estimated that 38% were realistic, 46% self‐favoring, and 16% other‐favoring in their perceptions. Among participants whose actual PA level was similar to peers, increasing age was associated with a self‐favoring bias. Among less and more physically active participants, however, age was not associated with this bias. Better self‐rated health and being male were also associated with a self‐favoring bias. These results suggest that a self‐favoring bias for PA exists in a significant proportion of middle‐aged and older adults, and it is more pronounced with increasing age, among those with better self‐rated health, and among men.     

Habit as moderator of the intention–physical activity relationship in older adults: a longitudinal study

This longitudinal study examined whether habit strength moderates the intention–physical activity (PA) relationship in older adults, within the framework of the attitude–social influences–efficacy (ASE) model and the theory of planned behaviour (TPB). A total of 1836 older adults (M _age?=?62.95?years, SD _age?=?8.17) completed a questionnaire on social cognitive constructs and PA habit strength at baseline, and six?months later a measure of PA. Three PA habit groups (i.e. low, medium and high) were composed, based on tertiles of the mean index score. Multi-group structural equation modelling analyses showed that intention significantly determined PA behaviour only in participants with a low or medium habit strength towards PA. This result suggests that PA is not intentional at high levels of habit strength and demonstrates the usefulness of incorporating habit in the ASE and TPB models. Results also showed that about half of the participants with a strong PA habit did not meet the recommended PA level. As strong habits may prevent intentional behavioural change and may hinder the receptiveness and openness for informational PA change strategies, additional intervention strategies, such as awareness raising and the use of implementation intentions, are needed for strongly habitual, but insufficiently active older adults.     

Do government brochures affect physical activity cognition? A pilot study of Canada's physical activity guide to healthy active living

Health Canada has published national physical activity (PA) guidelines, which are included in their 26-page Physical Activity Guide to Healthy Active Living (CPAG). To date, the use of CPAG as a motivational instrument for PA promotion has not been evaluated. The purpose of this study was to determine whether reading CPAG 1) increased motivational antecedents to engage in regular PA, and 2) increased regular PA intention and behaviour over 1 month. Participants included 130 randomly sampled Canadian adults (18 years or older) who were randomly mailed pack ages consisting of either 1) a questionnaire and a copy of CPAG, or 2) a questionnaire. Questionnaire items pertained to participants' sociodemographics, previous PA behaviours (Godin Leisure-Time Questionnaire) and PA motivation (theory of planned behaviour). Participants were then sent a follow-up questionnaire pertaining to their PA behaviours throughout the previous month. Results revealed significant interactions between the guide condition and previous activity status on instrumental behavioural beliefs about strength activities and subjective norms about endurance activities (p < 0.05), but all other factors were not significantly different. It was concluded that among previously inactive people, receiving this guide may change some informational/motivational constructs, but key motivational antecedents (affective attitude, perceived behavioural control) and outcomes (intention, behaviour) seem unaffected.     

Differential Risk Perceptions for Unintended Pregnancy,STDs, and HIV/AIDS Among Urban Adolescents: Some Preliminary Findings

Two pilot studies tested the hypothesis that adolescents perceive differential risks for unintended pregnancy (UP), sexually transmitted diseases (STDs), and human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS). The 1st study used a college sample consisting of 14 adolescents (21 years or younger) and 64 adults (over 21) who rated the likelihood that they and others would experience 15 health problems. The 2nd study used a community sample of 48 adolescents between 16 and 21 years of age who rated 11 health problems in a similar manner. Optimistic bias and uniqueness of risk in adolescents' perceived susceptibility to adverse sexual outcomes were examined. Optimistic bias is the difference between ratings of risk to self and risk to others, reflecting lower risk to self. Uniqueness of risk is the difference between ratings of risk and a baseline risk estimate (i.e., the mean rating for all non-sex-related health problems). Consistent with the hypothesis, adolescents perceived differential risks for UP, STDs, and HIV/AIDS. Implications for adolescent prevention programs are discussed.

Autonomous motivation,cardiorespiratory fitness,and exercise in rheumatoid arthritis: Randomised controlled trial

ObjectiveRheumatoid arthritis (RA) is an autoimmune disease, characterised by high-grade systemic inflammation, pain, and swollen joints. RA patients have an increased risk for cardiovascular disease (CVD). This study examined if a 3-month individualised RA-tailored exercise programme with one-on-one Self-Determination Theory (SDT)-based support for physical activity (PA) facilitated autonomous motivation, increased PA behaviour, and induced greater improvements in cardiovascular and RA-related disease characteristics, and wellbeing in RA, compared to a standard provision tailored exercise programme.Methods115 RA patients were randomised into either the SDT-based psychological intervention + exercise programme (experimental group) or an exercise programme only (control group). Cardiorespiratory fitness (primary outcome), self-reported PA, disease characteristics, CVD risk, wellbeing, and SDT constructs were assessed at baseline (pre-intervention), 3 months (post-intervention), 6 months, and 12 months follow-up. Mixed linear modeling was used to examine within- and between participant changes in these outcome measures.ResultsIn 88 patients with complete baseline data, cardiorespiratory fitness did not change from baseline to 3-, 6- or 12 months in either group. CVD risk, disease characteristics, wellbeing, and need satisfaction did not change, with the exception of diastolic blood pressure. Significant group by time interaction effects were found for functional ability (6- & 12-months), CVD risk (6-months) and PA (3-months). Autonomous motivation increased and controlled motivation decreased more in the experimental group compared to the control group at 3 months.ConclusionsDespite improving quality of motivation for exercise, no changes in cardiorespiratory fitness or other psychological and physiological health outcomes were found. This suggests more intensive support is needed when initiating an exercise programme to achieve health benefits in RA.     

Age and motivation predict gaze behavior for facial expressions

This study investigated age-related differences between younger (M = 25.52 years) and older (M = 70.51 years) adults in avoidance motivation and the influence of avoidance motivation on gaze preferences for happy, neutral, and angry faces. In line with the hypothesis of reduced negativity effect later in life, older adults avoided angry faces and (to a lesser degree) preferred happy faces more than younger adults did. This effect cannot be explained by age-related changes in dispositional motivation. Irrespective of age, avoidance motivation predicted gaze behavior towards emotional faces. The study demonstrates the importance of interindividual differences beyond young adulthood.     

Social support,social integration,and health-related quality of life over time: Results from the Fitness and Arthritis in Seniors Trial (FAST)

The present study tested whether baseline perceived social support and social integration predicted baseline and follow-up measures of health-related quality of life for 364 older adults with osteoarthritis. The findings are secondary analyses of a randomized controlled trial of an exercise intervention. Multiple regression analyses indicate that perceived social support was related to baseline measures of functioning in psychological (depressive symptoms, social functioning, and life satisfaction) and physical domains (self-rated disability, observed physical function, and perceived health), after accounting for demographic and clinical status factors. At 18-month follow-up (additionally controlling for exercise intervention and baseline outcomes), social support significantly predicted changes in psychosocial functioning, but was unrelated to changes in self-reported and observed physical health. The findings indicate that social support is an important predictor of long-term psychosocial outcomes, but is less important than baseline clinical status for physical health endpoints in this cohort of older adults. In contrast, social integration was not a consistent predictor of outcomes.     

Attachment Insecurity and Perceived Partner Suffering as Predictors of Personal Distress

This study examined the extent to which perceptions of partner suffering mediate the association between attachment insecurity (anxiety and avoidance) and personal distress among spouses of older adults with osteoarthritis. Fifty-three spouses watched two videos of targets (their partner and an opposite sex stranger) perform a pain-eliciting household task, and spouses were asked to rate their own distress and perceptions of the targets' pain. Spouses also completed self-report measures of trait attachment. Results revealed that attachment anxiety was associated with greater personal distress in reaction to the partner's suffering, and heightened perceptions of partner pain mediated this association. Avoidant attachment was associated with less distress in reaction to the partner's suffering, but not with less perceived pain. The results of this study identify an important mechanism linking attachment insecurity and heightened distress responses when observing the suffering of a significant other.     

Personality factors in older women's perceived susceptibility to diseases of aging

Personality correlates of older women's perceived susceptibility to breast cancer, heart disease, and osteoporosis were examined in a community sample of 312 women aged 40-86. A latent factor of general perceived susceptibility to disease was shown to underlie disease-specific perceptions of susceptibility. Affect-related personality traits (neuroticism, extraversion, optimism, worry, and self-deceptive enhancement) and internal and chance health locus of control predicted general perceived susceptibility. Perceived disease characteristics (e.g., perceived controllability, severity) and the use of cognitive heuristics (i.e., perceived similarity to those who contract each disease) also displayed marked consistency across the three distinct diseases. Finally, our results suggested that general beliefs about the characteristics of health threats and the use of cognitive heuristics may mediate the link between personality traits and perceived risk.     

Methodological Overview of A Self-Determination Theory-Based Computerized Intervention to Promote Leisure-Time Physical Activity

OBJECTIVES: To provide a methodological overview of a computerized intervention to promote leisure time physical activity (PA) and to apply self-determination theory (SDT) to PA initiation to better understand the psychological mechanisms underlying PA frequency, intensity, and duration in previously-sedentary individuals. DESIGN: Based on SDT, two computerized personal trainers were developed for use with sedentary young adults. One personal trainer was designed to be need-supportive, empathic, and structured while the other was designed to be more controlling, evaluative, and judgmental. METHOD: Participants are randomly assigned to work with either the need-supportive or controlling computerized personal trainer. They complete a series of 7 weekly training sessions. In between training sessions, participants complete daily records of PA behaviors and experiences including autonomous self-regulation and perceived competence for PA and PA frequency, intensity, and duration. POTENTIAL CONTRIBUTIONS: The design of this intervention and its theoretical basis have important implications for advancing the field of exercise science specifically and health behavior change more broadly. Computerized interventions have the benefit of standardizing intervention content as well as reducing clinical contact burden for practitioners. Daily recording procedures reduce the likelihood of retrospection bias and allow for the modeling of (1) daily fluctuations in PA behavior and (2) the psychological mechanisms believed to be involved in PA behavior (e.g., autonomous self-regulation). Finally, as a broad theory of human motivation, SDT is uniquely positioned to offer explanations for the conditions that are likely to promote both the initiation and maintenance of health behavior change.     

The Dynamics of Internalised and Extrinsic Motivation in the Ethical Decision-Making of Small Business Owners

We investigate the ethical behaviour of small business owners by focusing on individuals' motivations to comply with tax obligations. In a study of 330 small business owners, we assess the role of internalised motivation to pay taxes versus extrinsic motivation in driving tax compliance. First, we find that internalised and extrinsic motivation have distinct predictors. Internalised motivation is related to strong personal moral norms to comply and a sense that the fiscal system is fair. Extrinsic motivation is related to perceptions that penalties are severe, that checks are likely, and is associated with a perceived lack of tax knowledge. Second, we find that, when considered together, internalised motivation but not extrinsic motivation predicts self-reported tax compliance. Third, we test the undermining hypothesis by which the presence of extrinsic motivation may crowd out the positive effect of internalised motivation. We find evidence of a motivation crowding effect only at very high levels of extrinsic motivation. We discuss avenues for further integration of motivation theory in research on tax compliance behaviour, and more generally the study of regulatory compliance and ethical behaviour in business settings.     

Generativity and Political Participation in Old Age: A Mixed Method Study of Spanish Elders Involved in Political Organisations

This study has dual aims. First, it aims to explore the relationship between generativity and political participation, a neglected aspect of civic participation. Second, using different dimensions of generativity in a mixed methods study, it also aims to contribute to the theoretical and methodological literature on generativity as a multidimensional concept relevant to later life. This Spanish study involved a large survey utilising three different measures of generativity—generative concern, generative goals, and perceived cultural demands—to look for differences between older people actively engaged in political organisations and a comparison group. Results showed that older people from the two groups differed on all dimensions of generativity. Participants in political organisations showed significantly higher scores on generative concern, reported more generative goals in the present and future, and noted more perceived generative demands than comparison individuals. Overall, our findings suggest that generativity plays a key role in political engagement in later life, and, further, that our understanding of generativity in later life gains from a multidimensional assessment of the concept.     

The Effects of Social Identity and Perceived Autonomy Support on Health Behaviour Within the Theory of Planned Behaviour

The present study employed constructs from self-determination theory, social-identity theory, and the theory of planned behaviour to examine the combined effects that social identity and perceived autonomy support exerted on attitudes, intentions and health behaviour. A prospective design was employed measuring constructs from the theory of planned behaviour, group norms, group identification, and perceived autonomy support at baseline and physical activity behaviour 5 weeks later. Self-report questionnaires were administered to 231 pupils (male = 113, female = 118, M = 14.21 years, SD = .90). Hierarchical regression analysis demonstrated that group norms predicted participation in physical activities and attitudes, but only for participants who identified strongly with their group. Perceived autonomy support predicted attitudes, intentions and behaviour. The effects of perceived autonomy support and social-identity constructs were independent. It was concluded that both social identity and perceived autonomy support should be included in the theory of planned behaviour.
