Attributions for physical activity in very old adults: predicting everyday physical activity and mortality risk

Objectives: Although physical activity is recognised as a health-promoting behaviour for older adults, notable barriers exist that may reduce physical activity in this age group. Limited research has explored causal beliefs (attributions) as a barrier to physical activity. Our study assessed associations between older adults’ attributions about physical activity and objective health outcomes. Methods: We examined the role of attributions as a predictor of everyday physical activity (EPA) and subsequent mortality risk over a 10-year period (2006–2016) in a sample of older adults (M_age?=?87, N?=?261). Results: OLS and Cox proportional hazard regression analyses revealed older adults who endorsed more internal and uncontrollable attributions for limited activity (physical incapacity) when feeling unwell had lower subsequent EPA (β?=??0.18), and higher 10-year mortality risk (HR?=?1.46). Other attributions with different dimensional properties (e.g. internal and controllable) were not associated with EPA or mortality. Discussion: Findings suggest that causal beliefs older adults have about their physical activity can influence their future behaviour and longevity. Psychological treatments designed to discourage maladaptive attributional thinking for older populations who face barriers to physical activity may be an important avenue for future research.     

The effects of a brief time perspective intervention for increasing physical activity among young adults

Past research has demonstrated that health behavior is correlated with time perspective: long-term thinkers are more likely than short-term thinkers to engage in health protective behaviors and less likely to engage in health damaging behaviors. To date, however, no research has experimentally demonstrated that time perspective is causally related to health behavior. We designed a brief (three 1/2-h weekly sessions) time perspective intervention to enhance long-term thinking about physical activity and examined its efficacy among two samples of young adults who signed up for fitness classes at a university recreational facility. Participants were assigned to one of three conditions: time perspective intervention, goal-setting control intervention, and no-treatment control. In Study 1, physical activity levels were assessed at preintervention, at postintervention (3 weeks later), and at 10-week follow-up (7 weeks after completion of the intervention). Controlling for preintervention physical activity levels, time perspective participants reported increased levels of physical activity relative to both other groups at postintervention, and relative to the no-treatment group at 10-week follow-up. This study provides the first experimental evidence that the effects of health behavior interventions may be enhanced by increasing participants’ long-term time perspective, and that time perspective is causally associated with health behavior. Study 2 replicated some of the effects of Study 1 using a larger sample, a six-month follow-up interval, and improved measurement of outcome. Together Studies 1 and 2 suggest that time perspective is an important ingredient in interventions designed to promote physical activity.     

Evaluating the effectiveness of goal setting and textual feedback for increasing moderate‐intensity physical activity in adults

The purpose of this study was to evaluate the effectiveness of goal setting and textual feedback, without additional intervention components, for increasing moderate‐intensity physical activity, specifically the weekly number of intense steps measured by a Fitbit. A multiple baseline across participants design was employed with four participants using a Fitbit Flex accelerometer to measure intense steps. Results showed a substantial increase in weekly number of intense steps for three out of four participants following the intervention.     

Elucidating satisfaction with physical activity: An examination of the day-to-day associations between experiences with physical activity and satisfaction during physical activity initiation

Satisfaction with physical activity is known to be an important factor in physical activity maintenance, but the factors that influence satisfaction are not well understood. The purpose of this study was to elucidate how ongoing experiences with recently initiated physical activity are associated with satisfaction. Participants (n?=?116) included insufficiently active volunteers who initiated a self-directed physical activity regimen and completed daily diaries about their experiences for 28?days. We used multilevel models to examine the associations between experiences with physical activity and satisfaction. Significant between-person effects demonstrated that people reporting higher average levels of positive experiences and lower levels of thinking about the negative aspects of exercise were more likely to report higher levels of satisfaction (ps?<?.05). Positive experiences and perceived progress toward goals had significant within-person effects (ps?<?.01), suggesting that day-to-day fluctuations in these experiences were associated with changes in satisfaction. These findings elucidate a process through which people may determine their satisfaction with physical activity.     

Evaluating public posting,goal setting,and rewards to increase physical activity in children

In this study, we evaluated several components of a pedometer-based intervention with children in an elementary-school-aged classroom, across 24-h sessions. The intervention included combinations of self-monitoring, goal setting, feedback, and reinforcement, and data were analyzed at both the classroom level (i.e., average daily step totals) and the individual level (i.e., daily step totals), across phases. The highest levels of physical activity were observed when components of self-monitoring, public posting, goal setting, and feedback with reward were applied concurrently.     

Evaluating public posting,goal setting,and rewards to increase physical activity during school recess

We evaluated a pedometer‐based intervention consisting of public posting between two teams of students, with additional self‐monitoring, goal setting, and reinforcement components, to increase physical activity during school recess. In the absence of self‐monitoring, performance feedback alone did not increase physical activity levels above those observed during baseline. Additionally, higher levels of physical activity were observed when goal‐setting was introduced, with the highest levels of activity observed when raffle tickets could be earned for exceeding a specified step‐total goal.     

Affective and health-related outcome expectancies for physical activity in older adults

This study tests the effects of affective and health-related outcome expectancies on physical exercise, assuming stronger direct and indirect (via intention) effects from affective outcome expectancy to physical exercise than from health-related outcome expectancy to exercise. Physical exercise and social cognitive variables were assessed at baseline, and 6- and 12-month follow-up in 335 older adults (60–95 years of age). Applying structural equation modelling, there was a direct effect from affective, but not from health-related outcome expectancy on intentions and behaviour. Also, the indirect effect from self-efficacy on physical exercise via affective outcome expectancy was significant, whereas the mediation via health-related outcome expectancy was not. These findings emphasise the relative importance of affective versus health-related outcome expectancies in predicting intentions and physical exercise in older adults and highlight the importance to separate these facets at a conceptual level to enhance both theory development and health promotion.     

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.     

Zooming into daily life: within-person associations between physical activity and affect in young adults

Objective: Negative affect in daily life is linked to poorer mental and physical health. Activity could serve as an effective, low-cost intervention to improve affect. However, few prior studies have assessed physical activity and affect in everyday life, limiting the ecological validity of prior findings. This study investigates whether daily activity is associated with negative and positive evening affect in young adults.

Design: Young adults (N = 189, Mdn = 23.00) participated in an intensive longitudinal study over 10 consecutive days.

Main Outcome Measures: Participants wore accelerometers to objectively assess moderate-to-vigorous physical activity continuously throughout the day and reported their affect in time-stamped online evening diaries before going to sleep.

Results: On days when participants engaged in more activity than usual, they reported not only less depressed and angry evening affect but also more vigour and serenity in the evening.

Conclusion: Young adults showed both less negative and more positive affect on days with more activity. Physical activity is a promising health promotion strategy for physical and mental well-being.     

An exercise in nostalgia: Nostalgia promotes health optimism and physical activity

Objective: Previous research has shown that nostalgia, a sentimental longing for the past, leads to greater feelings of optimism, with other work demonstrating that optimistic thinking (general & health-orientated) is associated with better physical and psychological health. Integrating these two lines of research, the current studies examined whether nostalgia-induced health optimism promotes attitudes and behaviours associated with better physical well-being.

Methods: Participants, in three experiments, were randomly assigned to write about either a nostalgic or ordinary event. Following this, everyone completed a measure of health optimism (Studies 1–3), measures of health attitudes (Study 2) and had their physical activity monitored over the course of 2 weeks (Study 3).

Results: The results revealed that, in comparison to control conditions, nostalgic reverie led to greater health optimism (Studies 1–3). Further, heightened health optimism following nostalgic reflection led to more positive health attitudes (Study 2), and increased physical activity over a two-week period (i.e. Fitbit activity trackers; Study 3).

Conclusions: These findings highlight the importance of nostalgia on health attitudes and behaviours. Specifically, this work suggests that nostalgia can be used as a mechanism to increase the importance, perceived efficacy and behaviour associated with better physical health.     

Social interactions and physical symptoms in daily life: quality matters for older adults,quantity matters for younger adults

Objective: The present study examined how the different attributes of daily social interactions (quality and quantity) were associated with physical health, and how these associations vary with age.

Method: Using an ecological momentary assessment approach, participants from an adulthood lifespan sample (n = 172; aged 20–79 years) reported their social interactions five times daily, and physical symptoms and symptom severity at the end of each day, for one week.

Main outcome measures: Number of physical symptoms and physical symptom severity.

Results: There was a within-person main effect of the quality (positivity), but not the quantity (frequency), of social interactions on the number of reported physical symptoms and their severity. Moderation analyses further revealed that the quality of daily social interactions predicted fewer physical symptoms for older adults, but not for younger adults; in contrast, the frequency of social interactions predicted less severe physical symptoms for younger adults, but not for older adults. Finally, the reported severity of physical symptoms predicted less frequent but more positive social interactions the next day.

Conclusions: Our findings point to the bidirectional associations between social interactions and health and highlight the importance of considering individuals' developmental context in future research and interventions.     

Self-determination and functional persuasion to encourage physical activity

This research advances a novel approach to promoting physical activity, based on the principle of functional matching in persuasion, and the self-concordance (SC) of people's motivations for physical activity. We propose that SC establishes a positive or negative orientation toward the challenge inherent in physical activity, and that the maximum yield of participation will be achieved by communications that appeal to each orientation. In two studies, we compared how messages emphasizing challenge versus available social support would influence recipients’ self-reported practices of physical activity and attitudes toward a physical activity setting. As hypothesized, these messages had differential effects for recipients whose pursuit of physical activity varied in SC, such that favorable outcomes were more reliably associated with challenge-oriented messages among respondents higher in SC versus support-oriented messages among respondents lower in SC. The findings suggest the merits of using self-regulatory, compared with object- or personality-based, constructs and measures to indicate psychological functions of ongoing health-related behaviors.     

Memories of school recess predict physical activity enjoyment and social-emotional well-being in adults

School recess can provide social, emotional, and physical benefits for children. Yet, not all children experience recess the same, as inequity in access to recess and variability in the quality of recess exist. Researchers have yet to understand the long-term implications of recess experiences on adult well-being and physical activity behaviors. The purpose of this study was to explore the inter-relationships between memories of recess, physical activity, and social-emotional well-being. A total of 514 adults between the ages of 19 and 79 (M = 45.56; SD = 15.62) were surveyed via Prolific, a web-based research platform. Participants were asked about their memories of recess enjoyment and recess exclusion, and current physical activity levels, physical activity enjoyment, social isolation, social role satisfaction, and sense of meaning and purpose. Structural equation modeling analysis showed that memories of recess enjoyment were associated with meaning and purpose (β = 0.138, p < .05) and PA enjoyment (β = 0.183, p < .05). Furthermore, retrospective recess exclusion predicted current social isolation (β = 0.266, p < .05) and was negatively associated with retrospective recess enjoyment (β = −0.379, p < .05). Findings highlight the importance of childhood recess experiences and its impact on current physical activity behaviors, social isolation, and meaning and purpose later in life. Consistent with other research, early positive physical activity experiences, in the form of recess, appear to provide more assurances that one will engage in healthier lifestyle behaviors and more favorable psycho-socio-emotional profiles in adulthood.     

A brief intervention to increase physical activity behavior among adolescents using mental simulations and action planning

This study evaluated the effectiveness of a brief integrated theory-based intervention to increase physical activity (PA) among adolescents over a three-month follow-up period. A 2 (mental simulation: present vs. absent) × 2 (action planning: present vs. absent) × 4 (time: baseline vs. one-month vs. two-month vs. three-month follow-up) mixed-model randomized controlled design was adopted. Adolescents aged 14–15 years (N = 267) completed baseline psychological measures and self-reported PA followed by the relevant intervention manipulation, if appropriate, with follow-up measures collected one, two, and three months later. Results revealed no significant effects for the mental simulation and action planning strategies nor the interaction of the two strategies. However, among participants with low levels of baseline PA, participants in both mental simulation alone and action planning alone groups reported significantly higher levels of PA at one-month follow up than other groups, suggesting that individual intervention components may be effective in low-active adolescents.     

Changes in physical activity and sedentary behavior associated with an exercise intervention in depressed adults

BackgroundExercise is beneficial for depression, but less is known about its impact on post-intervention physical activity and sedentary behavior. The aim of this paper was to determine the extent to which participation in light-, moderate- and vigorous-intensity exercise intervention influenced habitual physical activity and sedentary behavior patterns in depressed adults.MethodsAccelerometer data was collected pre- and post-intervention from depressed participants randomized to one of three 12-week intervention groups: light (n = 21), moderate (n = 25) and vigorous (n = 22) exercise. Mixed models examined changes in time spent sedentary and in light and moderate-to-vigorous physical activity (MVPA); time accumulated in sedentary and MVPA bouts; and, number of MVPA bouts and interruptions in sedentary time.ResultsOverall sedentary time decreased while light activity time increased across all intervention groups but not significantly so. The light exercise intervention group reduced MVPA minutes (−8.22, 95% CI: −16.44, −0.01), time in MVPA bouts (−8.44, 95% CI: −14.27, −2.62), and number of activity bouts (−0.43, 95% CI: −0.77, −0.09). The moderate exercise intervention group reduced time in MVPA bouts (−6.27, 95% CI: −11.71, −0.82) and number of sedentary interruptions (−6.07, 95% CI: −9.30, −2.84). No changes were observed for the vigorous exercise intervention group.ConclusionsThe exercise intervention led to an increase in overall light physical activity and decrease in sedentary time, though neither change was statistically significant. Participation in the light and moderate exercise intervention groups was associated with reductions of time in MVPA bouts, but this was not evident for the vigorous exercise intervention group.     

Physical fitness and prior physical activity are both associated with less cortisol secretion during psychosocial stress

Background: Evidence linking fitness and decreased psychosocial stress comes from studies of athletes and typically relies upon self-report measures. Furthermore, there is little evidence regarding the impact of physical activity (PA) prior to a stressor. The aims of this study were to determine whether fitness and prior PA influence cortisol concentrations during psychosocial stress.

Methods: Seventy-five non-athletic participants took part in a submaximal walk prior to the Trier Social Stress Test for Groups (TSST-G). During the walk, fitness was assessed using heart rate (HR). A further 89 participants took part in the TSST-G without the walk. Stress responsiveness was assessed using salivary cortisol collected at 10-min intervals on seven occasions.

Results: Hierarchical multiple regression revealed that average walking HR accounted for 9% of the variance in cortisol secretion (P?=?.016), where a higher HR was associated with higher cortisol secretion. Between-subjects ANCOVA revealed that the walking group had a significantly lower cortisol secretion than the non-walking group (P?=?.009).

Conclusions: These findings indicate that fitter individuals have reduced cortisol secretion during psychosocial stress. They also indicate that prior PA can reduce cortisol concentrations during psychosocial stress and are suggestive of a role of PA in reducing the impact of stress on health.
