Affect variability and physical health: The moderating role of mean affect

Research has only begun to explore how affect variability relates to physical health and has typically not assessed long-term associations nor considered the moderating role of mean affect. Therefore, we used data from the Midlife in the United States Study waves 2 (N = 1512) and 3 (N = 1499) to test how affect variability predicted concurrent and long-term physical health while also testing the moderating role of mean affect. Results indicated that greater negative affect variability was associated concurrently with a greater number of chronic conditions (p = .03) and longitudinally with worse self-rated physical health (p < .01). Greater positive affect variability was associated concurrently with more chronic conditions (p < .01) and medications (p < .01) and longitudinally with worse self-rated physical health (p = .04). Further, mean negative affect played a moderating role such that at lower levels of mean negative affect, as affect variability increased, so did the number of concurrent chronic conditions (p < .01) and medications (p = .03) and the likelihood of reporting worse long-term self-rated physical health (p < .01). Thus, the role of mean affect should be considered when testing short- and long-term associations between affect variability and physical health.

Is Positive Affect as a Trait Related to Higher Heart Rate Variability in a Stressful Situation?

Most of the studies on the effect of trait positive affect (PA) and cardiovascular activity have focused on heart rate (HR) and blood pressure (BP) rather than heart rate variability (HRV). However, trait PA might sustain homeostasis for the autonomic system (ANS) by reducing activity in the sympathetic system (SNS) and increasing the activity in the parasympathetic system (PNS). A common index for the PNS is the vagal tone measured indirectly through HRV. The present study assessed whether trait PA influences cardiovascular response to various stress tasks by monitoring participants' HRV measured by RMSSD (root mean square of successive differences) along with HR and interbeat interval (IBI). A total of 54 participants performed various cognitive tasks and Trier Social Stress Tasks while their vital signs were monitored, and trait PA was measured with PANAS. The cognitive tasks included both high- and low-stress tasks, including fatigue-inducing 20 min Stroop tasks. The results showed overall higher HRV as measured by RMSSD for participants who have higher levels of trait PA, indicating more PNS activity compared with low-trait-PA individuals, particularly at the end of the task performance during the fatigue induction. High-trait-PA individuals also had a lower HR during the fatigue-inducing task and a higher IBI. The results support previous work by further indicating a more adaptive response and consequently better emotional regulation for high-trait-PA individuals in a complex, prolonged task setting.

The forgotten patient: A psychological perspective on the implementation of bariatric surgery guidelines

There is strong evidence demonstrating the impact of bariatric surgery on weight-loss and comorbidity improvement. In the UK, there is specific guidance to facilitate the assessment of a person's suitability for bariatric surgery. This paper highlights the clinical reality of routinely implementing this guidance, supported by literature and the perspectives of practicing psychologists. The consequences of the implementation of clinical guidelines within the context of the typical biopsychosocial profile of those referred for bariatric surgery are discussed. The ramifications of a screening approach rather than a clinical formulation-based approach to assessment, impact of a possible unconscious bias in commissioning and an overemphasis on a biomedical model approach to treatment are also presented. These contextual factors are argued to contribute to a population of "forgotten patients" that is, patients who have been assessed as not suitable for bariatric surgery, and thus "stuck" in their journey toward better health. For these individuals the only option left are energy balance only approaches, which are the very same approaches to weight-loss and comorbidity improvement that have been attempted, often for many years. Not only have these approaches not resulted in weight-loss and health improvement, they also fail to address the underlying psychological causes of obesity. Consequently, this lack of support means that patients continue to suffer from poor quality of life, with no clear pathway to improved health and wellbeing. This paper illuminates the clear gaps in weight management service provision, the implementation of guidelines in practice, and offers practical suggestions to reduce the unintended consequences of clinical guidelines for bariatric surgery.

Ageism and the Pandemic: Risk and Protective Factors of Well-Being in Older People

The COVID-19 pandemic has particularly affected the older population both in terms of the high number of victims and the psychological impact. Moreover, the pandemic has made older people more vulnerable to isolation and loneliness, and victims of ageism. The aim of the present study was to investigate the risk and protective factors for the well-being of older people during the pandemic. The role of positive affect, confidence in the future, current physical health, social isolation, loneliness, and ageism were analysed. A self-report questionnaire was administered to 1301 participants (mean age: 77.3 years, DS: 5.46), almost equally distributed by gender (56.1% female). Descriptive and correlational analyses were performed, together with SEM. The results showed that perceived age discrimination positively predicts loneliness and negatively and indirectly predicts well-being. Furthermore, positive affect, confidence in the future, and current physical health are protective factors, while loneliness, social isolation, and ageism are risk factors. Future emergency policies must take into account the impact of such actions on the well-being of this segment of the population.

Fostering Engagement, Reflexivity, and 21st-Century Skills in Middle School: A Pilot Collaborative Action Research on Identity Formation with Adolescent Co-Researchers

Identity construction during adolescence constitutes a primary psychosocial developmental task. A growing body of research has addressed the importance of school education in fostering adolescents' identity formation and the skills they need to thrive. Although several studies aimed at defining the factors contributing to a coherent, stable, and integrated identity formation, none sought to investigate this question from the adolescents' perspective. This contribution aimed to explore new ways of fostering 21st-century skills among adolescents through action research. Five adolescents aged 13 to 15 participated in the research process, creating a survey to answer a research problem mainly focused on identity construction in adolescence. A reflexive analysis of the co-research process highlighted the interest in involving adolescents as co-researchers to foster their social and emotional skills. The deployment of the resulting survey in a sample of 1210 adolescents from the general population highlighted the importance of gender diversity for constructing various dimensions of identity.

Do Positive Psychological Factors Equally Predict Resistance to Upper Respiratory Infections in African and European Americans?

Research has consistently shown that positive psychological constructs are linked to better physical health, but few studies have examined the role that race plays in this connection. We explored whether positive self-evaluations were equally protective against upper respiratory infection for 271 African American adults and 700 European American adults in a series of virus-exposure studies. Participants were assessed at baseline for psychological functioning and physical health, quarantined and exposed experimentally to a respiratory virus, and then monitored for infection and symptoms. Regression analyses revealed significant interactions between race and multiple positive psychological factors; several factors that were helpful to European Americans were unhelpful or even harmful to African Americans. Building on past work showing cross-cultural variation in the health correlates of affect, this study provides evidence that the health benefits of positive psychological constructs may not be universal and points to the need to explore factors that underpin these observed differential patterns.

The subcomponents of affect scale (SAS): validating a widely used affect scale

OBJECTIVE

There is a need for a brief affect scale that also encompasses different components of affect relevant for researchers interested in physiological and health outcomes. The Subcomponents of Affect Scale (SAS) meets this need. This 18-item scale has nine positive and nine negative affect items encompassing six subscales (calm, well-being, vigour, depression, anxiety, anger). Previous research using the SAS has demonstrated its predictive validity, but no work has tested its subscale structure or longitudinal validity.

DESIGN

Data from the Common Cold Project in which individuals (N = 610) completed the SAS over the course of seven days were used.

RESULTS

Confirmatory factor analysis demonstrated the reliability of the subscale structure of the SAS across seven days (positive affect subscale structure: CFIs ≥ 0.98; negative affect subscale structure: CFIs ≥ 0.94 with day 6 CFI = 0.91) and tests of factorial invariance showed the scale is valid to use over time.

CONCLUSIONS

These results confirm the psychometric validity of the subscale structure of the SAS and imply that the subscales can be used longitudinally, allowing for its use in health research as well as non-health research that can benefit from its subscale structure and longitudinal capabilities.

Moving Past the One-Size-Fits-All Education-Training Model of Police Academies to the Self-Prescribed Individualized Exercise Prescription Model

Law enforcement agencies generally employ the "one-size-fits-all" education-training model. Its effectiveness compared to alternative training models has been under scrutiny. Physical fitness scores of Serbian male (n = 98) and female (n = 79) police cadets during their yearly evaluation were compared. Cadets trained for the first 3 years with the "one-size-fits-all" model. In the fourth year, they self-prescribed an individualized exercise program based on the obtained curriculum knowledge. A two-way MANOVA revealed a significant effect of academic years on combined variables (p < 0.001) and significant differences between academic years for deadlift, half squat, standing long jump, sit-ups and 12-min Cooper test time (p < 0.001). Sex also had a significant main effect on combined variables (p < 0.001) with males outscoring females on all of the fitness assessments. For pull-ups, there was a significant year * sex interaction (p = 0.01) with the third year to be pivotal for female and male performance, respectively. In conclusion, the use of a "one-size-fits-all" model, presented differences in physical fitness scores between the years one to three, pointing to its questionable effectiveness. On the contrary, the self-prescribed individualized exercise program of the fourth year elicited greater fitness scores, indicating the need to evaluate the applicability of such a training model more.

The Associations Between Daily Activities and Affect: a Compositional Isotemporal Substitution Analysis

BACKGROUND

Daily activities are associated with affective experiences. A 24-h day can be separated into five mutually exclusive activity types: sleep, awake in bed, moderate-to-vigorous physical activity (MVPA), light-intensity physical activity (LIPA), and sedentary behavior (SB). Most research has examined these activities independently and not collectively, yet increased time in one activity must be offset by decreasing other activities. Using compositional isotemporal substitution analyses, this study examined the associations between time spent in daily activities and affect, including both high and low arousal positive and negative affect.

METHOD

Across three separate studies, daily activities and affect were measured throughout 7-15 days (M_days = 10) in 361 healthy community adults (72.5% females, M_age = 22.79 years). Activities were objectively assessed using accelerometry and self-reported affect was assessed using repeated ecological momentary assessments. Minutes spent in each activity and affect values across the three studies were averaged for each participant.

RESULTS

Longer sleep duration at the expense of time awake in bed was associated with lower high arousal negative affect (e.g., nervousness, b =  - 0.24, p = .007). More MVPA at the expense of LIPA or SB was associated with higher high arousal positive affect (e.g., happiness, b = 0.35, p = .027). Activity composition was not associated with low arousal positive or negative affect (all p ≥ .06).

CONCLUSION

Associations between 24-h activity composition and affect differed based on types of activities, types of affect, and the interrelationships between activities within the composition. Findings can aid interventions to develop integrated guidance on the optimal activity patterns for mental health.

Associations between positively valenced affect and health behaviors vary by arousal

Evidence is mixed with regard to whether positively valanced affect (PA) is associated with engagement in health behaviors. Both affective arousal (activated/deactivated) and level of analysis (between and within-person) may influence such associations. Adults (N = 121; 25-65 years) completed ambulatory assessments of affect and daily reports of sleep, diet, and physical/sedentary activity. Patterns of association were generally consistent at between and within-person levels, although associations varied by arousal. Activated PA was positively associated with action tendencies (i.e., higher physical activity, lower sedentary activities) and riskier behaviors (such as poor diet) whereas deactivated PA was positively associated with engaging in satiety and rest (i.e., better diet, better sleep quality, and more sedentary activity). Results were maintained when covarying for indicators of relative socioeconomic advantage and neuroticism. Overall, arousal appears to be related to the nature of the associations between PA and health behaviors, highlighting the importance of assessing and evaluating a range of arousal states.

Development of a Nostalgic Remembering Intervention: Feeling Safe in Dyads Receiving Palliative Care for Advanced Heart Failure

BACKGROUND

Dyads receiving palliative care for advanced heart failure are at risk for the loss of feeling safe, experienced as a fractured sense of coherence, discontinuity in sense of self and relationships, and strained social connections and altered roles. However, few theory-based interventions have addressed feeling safe in this vulnerable population.

PURPOSE

The purpose of this article is to describe the development of the Nostalgic Remembering Intervention to strengthen feeling safe and promote adaptive physiological and psychological regulation in dyads receiving palliative care for heart failure.

CONCLUSIONS

Systematic intervention development is essential to understand what, for whom, why, and how an intervention works in producing outcomes. Program theory provided a systematic approach to the development of the Nostalgic Remembering Intervention, including conceptualization of the problem targeted by the intervention, specification of critical inputs and conditions that operationalize the intervention, and understanding the mediating processes leading to expected outcomes.

CLINICAL IMPLICATIONS

Creating a foundation for cardiovascular nursing research and practice requires continued, systematic development of theory-based interventions to best meet the needs of dyads receiving palliative care for heart failure. The development of the Nostalgic Remembering Intervention to strengthen feeling safe in dyads provides a novel and relevant approach.

How strongly connected are positive affect and physical exercise? Results from a large general population study of young adults

Background

Previous research has shown a link between low positive affect (PA) and numerous physical and psychological well-being outcomes but, recent research has raised the possibility that this relationship may be driven by physical activity. Thus, we were interested in exploring the PA-exercise connection by examining this relationship across differing levels of body mass and athleticism. We also looked at whether the item “active” that is used in many PA assessments was responsible for this effect.

Method

Participants were part of the Norwegian SHoT2018 national survey of 50,054 young adults (mean age = 23.2, 68.9% women), who completed electronic surveys about their exercise levels (duration, frequency and intensity) and affect.

Results

There was a clear and strong dose-response association between current state PA and the duration, frequency and intensity of exercise. For example, duration, magnitude, and slope effects were strongly driven by regular exercisers who had more than a 20-fold greater likelihood of being in the highest PA deciles compared to the least frequent exercisers. These dose-response connections replicated across both healthy and overweight BMIs, as well as in elite athletes. Removing the word “active” from the PA measure substantially reduced the size of this association, although the dose-response relationship remained.

Conclusion

The observed strong connections have critical implications for health researchers and clinicians, and point to a need to carefully consider what types of activities are most strongly tied to well-being.

Is stressor-evoked cardiovascular reactivity a pathway linking positive and negative emotionality to preclinical cardiovascular disease risk?

Stressor-evoked cardiovascular reactivity, trait positive emotionality, and negative emotionality are all associated with cardiovascular disease. It is unknown, however, whether cardiovascular reactivity may constitute a pathway by which trait positive or negative emotionality relates to disease risk. Accordingly, this study modeled the cross-sectional relationships between trait positive and negative emotionality, stressor-evoked cardiovascular reactivity, and severity of a subclinical vascular marker of cardiovascular risk, carotid artery intima-media thickness (CA-IMT). The sample consisted of healthy, midlife adults free from clinical cardiovascular disease (N = 286; ages 30-54; 50% female). Trait positive and negative emotionality were measured by three questionnaires. Heart rate and blood pressure reactivity were assessed across three stressor tasks. CA-IMT was assessed by ultrasonography. Latent factors of positive and negative emotionality, blood pressure reactivity, heart rate reactivity, and CA-IMT were created using structural equation modeling. Greater negative emotionality was marginally associated with more CA-IMT (β = .21; p = .049), but lower blood pressure reactivity (β = -.19; p = .03). However, heightened blood pressure (β = .21; p = .03), but not heart rate reactivity (β = -.05; p = .75), associated with greater CA-IMT. Positive emotionality was uncorrelated with cardiovascular reactivity (blood pressure: β = -.04; p = .61; heart rate: β = .16; p = .11) and CA-IMT (β = .16; p = .07). Although trait negative emotionality associates with a known marker of cardiovascular disease risk, independent of positive emotionality, it is unlikely to occur via a stressor-evoked cardiovascular reactivity pathway.

Positive Affect Is Associated With Less Memory Decline: Evidence From a 9-Year Longitudinal Study

Memory decline is a concern for aging populations across the globe. Positive affect plays an important role in healthy aging, but its link with memory decline has remained unclear. In the present study, we examined associations between positive affect (i.e., feeling enthusiastic, attentive, proud, active) and memory (i.e., immediate and delayed recall), drawing from a 9-year longitudinal study of a national sample of 991 middle-age and older U.S. adults. Results revealed that positive affect was associated with less memory decline across 9 years when analyses controlled for age, gender, education, depression, negative affect, and extraversion. Findings generalized across another measure that assessed additional facets of positive affect, across different (but not all) facets of positive affect and memory, and across age, gender, and education; findings did not emerge for negative affect. Reverse longitudinal associations between memory and positive affect were not significant. Possible pathways linking positive affect and memory functioning are discussed.

Replication and the Establishment of Scientific Truth

The idea of replication is based on the premise that there are empirical regularities or universal laws to be replicated and verified, and the scientific method is adequate for doing it. Scientific truth, however, is not absolute but relative to time, context, and the method used. Time and context are inextricably intertwined in that time (e.g., Christmas Day vs. New Year's Day) creates different contexts for behaviors and contexts create different experiences of time, rendering psychological phenomena inherently variable. This means that internal and external conditions fluctuate and are different in a replication study vs. the original. Thus, a replication experiment is just another empirical investigation in an ongoing effort to establish scientific truth. Neither the original nor a replication is the final arbiter of whether or not something exists. Discovered patterns need not be permanent laws of human behavior proven by the pinpoint statistical verification through replication. To move forward, phenomenon replications are needed to investigate phenomena in different ways, forms, contexts, and times. Such investigations look at phenomena not just in terms the magnitude of their effects but also by their frequency, duration, and intensity in labs and real life. They will also shed light on the extent to which lab manipulations may make many phenomena subjectively conscious events and effects (e.g., causal attributions) when they are nonconsciously experienced in real life, or vice versa. As scientific knowledge in physics is temporary and incomplete, should it be any surprise that science can only provide "temporary winners" for psychological knowledge of human behavior?

Does laughing have a stress-buffering effect in daily life? An intensive longitudinal study

Positive affect is associated with alleviating mental and physiological stress responses. As laughter is a common physiological operationalization of positive affect, we investigated whether the effects of experiencing a stressful event on stress symptoms is lessened by frequency and intensity of daily laughter. Using an intensive longitudinal design, we ambulatory assessed the self-reported experience of stressful events, stress symptoms and the frequency as well as the intensity of laughter in university students' daily lives. Our hierarchical ecological momentary assessment data were analyzed with multilevel models. The results support the stress-buffering model of positive affect: We found that the frequency of laughter attenuated the association between stressful events and subsequent stress symptoms. The level of intensity of laughter, however, was found to have no significant effect. Future studies should use additional psychophysiological indicators of stress and straighten out the differential contributions of frequency and intensity of daily laughter.

Positive Affect and Health: What Do We Know and Where Next Should We Go?

Positive affect (PA) is associated with better health across a wide range of physical health outcomes. This review reflects on why the study of PA is an essential component of our understanding of physical health and expands on pathways that connect these two variables. To encourage forward movement in this burgeoning research area, measurement and design issues in the study of PA and health are discussed, as are the connections between PA and a range of different health outcomes. Plausible biological, social, and behavioral pathways that allow for positive feelings to get under the skin and influence physical wellness are detailed and framed in the context of several theoretical models. Finally, new directions for the field and important methodological and interpretative considerations that are essential to moving this important research area forward are explored.
