Trajectories Of Positive Affect Research Articles

Divergent trajectories of positive affect following maladaptive and non-maladaptive exercise among individuals with binge-spectrum eating disorders.

Individuals with eating disorders (EDs) often engage in maladaptive exercise (e.g., feeling driven, or to "compensate" for eating) which maintains eating pathology. Maladaptive exercise has been theorized to help individuals with EDs regulate emotions by enhancing positive affect (PA) and reducing negative affect (NA) associated with binge episodes and poor body image. However, no research has considered the presence of non-maladaptive exercise or evaluated this theory in binge-spectrum EDs. This study evaluated affective trajectories pre- and post-exercise and examined exercise type (maladaptive or non-maladaptive) as a moderator. We recruited adults with binge-spectrum EDs (N=107; n=84 endorsed exercise) to complete a 7- to 14-day ecological momentary assessment protocol assessing NA (anxiety, guilt, and sadness), PA (excitement and cheerfulness), and exercise. There was a significant quadratic trajectory of PA pre-exercise, suggesting that the upward trajectory of PA leveled out as it moved closer to an exercise episode. Exercise type significantly moderated the cubic trajectory of PA post-exercise, such that the upward trajectory of PA accelerated in the hours following non-maladaptive exercise episodes while the downward trajectory of PA accelerated in the hours following maladaptive exercise episodes. No trajectories of NA demonstrated significant effects. Pre-exercise trajectories of PA may reflect positive expectancies around exercise. Post-exercise trajectories of PA suggest that non-maladaptive exercise promotes increased PA. Future research should evaluate when, and for whom, exercise serves to regulate affect and examine other momentary risk factors of exercise in EDs. Individuals with EDs often engage in maladaptive exercise (e.g., feeling driven, or to "compensate" for eating). Maladaptive exercise has been theorized to help individuals with EDs regulate emotions. This study evaluated affective trajectories pre- and post-exercise and examined whether exercise type (maladaptive or non-maladaptive) changed these trajectories. Pre-exercise trajectories of PA may reflect positive expectancies around exercise. Post-exercise trajectories of PA suggest that non-maladaptive exercise promotes increased PA.

What does it cost you to get there? The effects of emotional journeys on daily outcomes.

Scholarly understanding of emotions and emotion regulation rests on two incompatible truths-that positive emotions are positively beneficial and should be pursued, and that changing emotions may come at a cost. With both perspectives in mind, to really conclude that pursuing higher positive affect (PA) is a worthy journey, we must take into account the cost of that journey itself. We build from the affect shift literature and draw on self-regulation theories to argue that, although end-states characterized by more positive (and fewer negative) emotions will be beneficial, the emotional changes required to "get there" will have consequences for employee regulatory resources and subsequent behavior. In Study 1, we use experience sampling methodology to track employee emotional journeys-changes in emotions in terms of directionality (e.g., toward pleasure and away from pain) and distance (i.e., magnitude of change in terms of intensity changes within-emotions as well as magnitude of change in activation/valence level between emotions)-that capture the amount of emotion regulation preceding emotion end-states. Teasing apart variance attributable to the end-state versus the journey, we demonstrate that steeper daily PA trajectories (steeper increases in intensity of positive, activated emotions) and valence trajectories (steeper movement away from more negative emotions toward more positive emotions) lead to psychological depletion, ultimately triggering interpersonal counterproductive work behaviors and harming citizenship and performance. In Study 2, we test our core propositions in a lab experiment, demonstrating that different emotional journeys "leading up" to the same affective end-state can change the meaning of that end-state.

A Mental Imagery Micro-Intervention to Increase Positive Affect in Outpatient CBT Sessions (PACIfIC): Study Protocol of a Randomized Controlled Implementation Trial.

Recent findings indicated that mental disorders are associated with both an up-regulation of negative affect and a down-regulation of positive affect (PA) as distinct processes. Established treatment approaches focus on the modification of problems and negative affect only. Experimental paradigms in healthy samples and research on strengths-based approaches showed that fostering PA may improve psychotherapy process and outcome. Specific and easily implementable interventions targeting PA in treatment sessions are scarce. Mental imagery was shown to be a promising strategy for boosting positive emotional experiences. The PACIfIC-study is planned as a longitudinal randomized-controlled trial in the context of cognitive behavioral therapy, implemented at a German outpatient training and research center. In the process analysis, trajectories of PA over the first twelve treatment sessions will be examined with weekly questionnaires. In the intervention analysis, a six-minute positive mental imagery intervention to enhance PA will be developed and tested. The intervention is implemented with loudspeakers at the beginning of each session for a standardized induction of PA. The experimental group will be compared to an active control group (neutral mental imagery) and treatment as usual. Procedures in all treatment arms are parallelized. Main outcomes after twelve sessions of psychotherapy will be psychosocial resources, resilience and self-esteem (theory-driven), as well as psychopathology and working alliance (secondary outcome). Multilevel modeling will be conducted to address the nested data structure. Study results may have implications on the consideration of positive constructs in mental disorders and the implementation of strengths-based interventions in psychotherapy.

Associations Between Age-Related Changes in Positive Affect and Physical Functioning: The Role of Education

Increasing research points to the relevance of educational attainment for positive emotional experiences and physical functioning across adulthood. However, little is known about how age-related developments in positive affect and physical functioning differ by educational attainment. This study used longitudinal data of 10,893 individuals (60–80 years) from the Health and Retirement Study to examine whether educational attainment moderates trajectories of positive affect and physical functioning and their interrelations over 12 years. Initial results from multiple-group bivariate growth models revealed that individuals with less formal education have lower positive affect and poorer physical functioning at baseline. There was, however, no evidence that longitudinal changes in positive affect, longitudinal changes in physical health, and coupled changes between both variables varied with educational attainment. These initial findings suggest that lower educational attainment is primarily related to lower levels of positive affect and physical functioning, but not to greater age-related declines or their interrelations.

Experience, vulnerability, or overload? Emotional job demands as moderator in trajectories of emotional well-being and job satisfaction across the working lifespan.

Employees exert emotional effort in order to perform their work effectively, albeit to varying degrees based on their occupation. These emotional job demands (EJDs) affect employees' well-being, yet evidence is mixed as to whether these effects are positive or negative. One limiting factor in extant studies is that they investigated short-term effects or cross-sectional relationships between EJDs (usually assessed at the employee level) and work outcomes. The present study used an accelerated longitudinal design with a 10-year timespan of data (effectively covering the whole working lifespan) to test the effects of EJDs at the occupational level on long-term trajectories of well-being. Drawing on the model of strengths and vulnerabilities integration (SAVI) from the lifespan psychology literature, we tested three competing effects: an experience effect (EJDs predict increased well-being), a vulnerability effect (EJDs predict diminished well-being), and an overload effect (a non-linear relationship in which very high levels lead to more unfavorable trajectories). Using data of N = 2,478 working adults in Germany drawn from the Socioeconomic Panel Study (SOEP), in tandem with data on EJDs from the Occupational Information Network (O*NET), we found an overload effect of EJDs on trajectories of positive affect and job satisfaction. However, EJDs did not influence trajectories of negative affect. We discuss the implications of our findings for theory and practice. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Longitudinal associations between positive affect and relationship quality among children and adolescents: Examining patterns of co-occurring change.

The broaden-and-build theory of positive emotions suggests that the experience of positive affect (PA) and positive interpersonal experiences should mutually reinforce each other over time, potentiating upward spirals of PA and social well-being. Informed by this upward spirals hypothesis, the present study used parallel process latent growth curve modeling to evaluate co-occurring trajectories of PA and parent- and peer-relationship quality in a sample of 680 youth aged 8 to 16 years (M = 11.87, SD = 2.41, 56.7% female). Youth PA and relationship quality were assessed every 18 months for 3 years (3 total assessments). Results of parallel process latent growth curve modeling analyses indicated positive correlations between trajectories of PA and trajectories of both parent- and peer-relationship quality. Consistent with tenets of the broaden-and-build theory of positive emotions, the findings suggest that youth PA and experiences of high-quality relationships demonstrate reciprocal patterns of growth, with implications for youth health and well-being.

Positive Affect Over Time and Emotion Regulation Strategies: Exploring Trajectories With Latent Growth Mixture Model Analysis.

The influence of Positive Affect (PA) on people’s well-being and happiness and the related positive consequences on everyday life have been extensively described by positive psychology in the past decades. This study shows an application of Latent Growth Mixture Modeling (LGMM) to explore the existence of different trajectories of variation of PA over time, corresponding to different groups of people, and to observe the effect of emotion regulation strategies on these trajectories. We involved 108 undergraduates in a 1-week daily on-line survey, assessing their PA. We also measured their emotion regulation strategies before the survey. We identified three trajectories of PA over time: a constantly high PA profile, an increasing PA profile, and a decreasing PA profile. Considering emotion regulation strategies as covariates, reappraisal showed an effect on trajectories and class membership, whereas suppression regulation strategy did not.

RACIAL-ETHNIC DIFFERENCES IN THE EFFECTS OF POSITIVE AND NEGATIVE AFFECT, AND DEPRESSION ON COGNITIVE TRAJECTORIES

Purpose of study: This study investigated (1) whether positive affect(PA), negative affect(NA), and depression are related to trajectories of cognitive functioning among older adults, (2) whether PA or NA could moderate the relationship between depression and cognitive trajectories, and (3) whether there are racial/ethnic differences in the relationships among PA, NA, depression and cognitive trajectories. Design and Methods: Growth-curve modeling was conducted using the sample of 10,289 individuals in the U.S. aged 50 or older from the 2006-2014 Health and Retirement Study. Racial/ethnic groups in this study were non-Hispanic Whites (NHW, n=8.009), African Americans (AA, n=1,428), Hispanics (n=611), and others (n=241). Results: After adjusting for covariates, PA showed positive effect, and depression had negative effect on cognitive functioning trajectories (p < .05, z = 8.76, 95% CI= 0.27, 0.43; p < .05, z = -6.38, 95% CI= -0.19, -0.10). Racial/ethnic minorities (i.e., AA, Hispanics, others) exhibited lower cognitive functioning over time compared to NHW. PA significantly moderated the effect of depression on cognitive trajectories (p < .05, z = - 8.04, 95% CI = -0.19, -0.11), and the protective effect of PA against cognitive decline was pronounced for AA (p < .05, z = 2.75, 95% CI = 0.10, 0.63). Conclusion: Findings suggest that PA may protect against cognitive decline in older adults, providing a buffer against the negative effect of depression or racial/ethnic minority status on cognitive trajectories. Potential intervention strategies are discussed to assist older adults in maintaining and improving PA to promote cognitive health.

Patterns of Positivity: Positive Affect Trajectories Among Infants of Mothers with a History of Depression.

This study examined positive affect (PA) trajectories over the first year of life among infants of mothers with a history of depression (N = 191) as well as predictors (i.e., maternal prenatal and postpartum depression symptoms, maternal parenting behaviors) of those trajectories. Infant PA was observed in play and feeding tasks during lab visits at 3, 6, and 12 months of age; parenting behaviors were observed at 3 months. Mothers completed questionnaires regarding their symptoms of depression throughout the prenatal period and during the first 3 months postpartum. Growth curve analyses indicated that infant PA increased across time, and this finding replicated across both the play and feeding tasks, though increases slowed over time. Neither maternal prenatal nor postpartum depression symptoms predicted infants' PA trajectories, but mothers' PA, positive parenting, and disengaged parenting were associated with infant PA during the play task. Our finding that infant PA increased over the first year postpartum suggests PA trajectories among infants of mothers with a history of depression may be indices of resilience, despite risks associated with their mothers' history of depression. Furthermore, this study highlights parenting behaviors that may be important targets of prevention and early intervention efforts to bolster infant PA.

Borderline personality disorder traits and affect reactivity to positive affect induction followed by a stressor

Background and objectivesAffective hyperreactivity is a core feature of Borderline Personality Disorder (BPD), yet little is known about reactivity of positive affect (PA). Objectives were to explore the relationship between BPD traits and affect reactivity in response to a personalized PA-induction and a subsequent stressor. Patient status (seeking outpatient treatment for personality-related problems; yes/no), depressive symptoms, and age were examined as alternative predictors of affect reactivity. MethodsOne hundred and eight females (35 patients) reported on their BPD and depressive symptoms. They completed the Best Possible Self-exercise and a modified Trier Social Stress Task. Trajectories of high and low arousal PA (HAP and LAP) and negative affect (NA) were analyzed with mixed regression modelling. ResultsPatient status (for HAP) and depressive symptoms (for LAP and NA) predicted affect reactivity better than BPD traits. Patients showed a weaker HAP increase after PA-induction, and a similar HAP decrease after the stressor, compared to non-patients. Higher depressive symptoms predicted stronger improvement of LAP and NA after PA-induction, and less pronounced deterioration of LAP and NA after the stressor, relative to baseline. LimitationsThe sample was a convenience sample amplified with outpatients. Future research should (1) use clinical groups, (2) randomize to neutral vs. PA-induction, and (3) continue to differentiate between HAP and LAP. ConclusionsOur results do not support models postulating BPD-specific affective hyperreactivity. HAP and LAP have different trajectories, depending on the degree of psychopathology. The resilience-enhancing potential of a PA-focus in psychotherapy needs further research.

Stressful work conditions, positive affect, and physical health of middle-aged couples: A dyadic analysis.

This study investigated actor and partner effects involving middle-aged husbands' and wives' stressful work conditions (SWCs), positive affect (PA), and health outcomes in a dyadic trajectory context in three steps. First, examination of husbands' and wives' individual trajectories showed significant interindividual variations in SWCs and PA over time. Second, a dyadic growth curve model incorporating both husbands' and wives' growth curves of SWCs and PA showed that husbands' and wives' trajectories of SWCs over their early middle years (1991-1994) were negatively associated with their own parallel trajectories of PA independent of depressive symptoms trajectories. Finally, most of the growth factors of PA trajectories of husbands and wives (1991-1994) predicted their own residual changes in physical illness and overall physical health in 2001. In dyadic models, although contemporaneous correlations between most of the study constructs between husbands and wives were significant, all partner effects involving growth parameters of SWCs, PA, and health outcomes were not significant. Most of the indirect effects from SWCs growth factors to health outcomes through PA were significant. The findings suggested that PA was an important health resource for middle-aged husbands and wives that mediates the influence of one's SWCs on own physical health outcomes.

Economic hardship, positive affect, and marital processes over middle years

Family economic hardship (FEH) can negatively impact the quality of marital relationships, and research has shown that increased distress of husbands and wives at least partially mediates this association. Research has shown that FEH not only increases feelings of distress but also depletes individuals’ positive feelings. The mediating role of positive affect (PA), however, has received less attention. The current study used data from the Iowa Midlife Transitions Project with a sample of 370 married couples providing data from 1991 to 2001. Latent growth curves were estimated for families’ economic hardship and spouses’ PA. Increasing FEH over time generally resulted in the depletion of individuals’ PA after controlling for each spouse’s negative personality characteristics. These growth curves were included in a structural equation model ultimately assessing spouses’ marital quality (MQ). PA trajectories were related to hostile couple context, which was associated with reduced MQ. Findings emphasize the long-term consequences of FEH across middle adulthood on subsequent marital processes through both intra-individual (i.e., PA) and inter-individual (i.e., marital hostility) processes, suggesting that effective prevention and intervention efforts must account for influences at multiple levels and over extended periods of time on MQ. Furthermore, these findings support efforts aiming to strengthen positive psychological resources, rather than reducing psychological distress, as a means to improve MQ.

Association of Positive Affect with Cognitive Health and Decline for Elder Mexican Americans.

The goal of this study was to investigate the linkages of positive affect (PA) with cognitive health and its decline among elder Mexican Americans. We conducted secondary analysis of longitudinal data from the Sacramento Area Latino Study on Aging (SALSA). We used the structural equation modeling framework to achieve three specific aims: (1) identify a valid measure of PA, (2) describe within-person trajectories of PA and cognitive health, and (3) test the inter-relations of these two processes over time. Results showed that, on average, PA and cognitive ability (including verbal memory) decreased over time. Yet, there was significant variability in these patterns of change. Bivariate latent growth curve models showed significant correlations of baseline levels and rates of change of PA and cognitive ability even after controlling for age, education, sex, bilingualism, and depression. Results support the hypothesis that increases and decreases in PA tend to be related to increases and decreases in cognitive health at old age among Mexican Americans.

Affective experience across the adult lifespan: An accelerated longitudinal design.

Recent research investigating the course of affective development across the adult life span has incorporated both cross-sectional and longitudinal data in analyses to understand the aging-affect relationship. Most of these studies, however, have not provided an empirical test to determine whether the cross-sectional and longitudinal data can be combined to infer developmental processes. Utilizing an age heterogeneous sample followed over a 10-year span (N = 1,019, Mage = 54.14 ± 13.06), the present study used an accelerated longitudinal design to investigate whether cross-sectional age differences could be found in longitudinal aging trajectories of positive affect (PA), negative affect (NA), and their confluence (i.e., affect optimization, the experience of PA relative to NA). Additionally, age-related differences in poignancy, co-occurrences of PA and NA, were examined. Absence of cross-sectional age-differences in the estimated longitudinal aging trajectories of PA and affect optimization suggested that a developmental process could be inferred; whereas, the longitudinal aging trajectories for NA showed cross-sectional age differences. PA and affect optimization showed a cubic relationship with age; NA showed decreases across adulthood; and poignancy showed age-related increases across adulthood. Self-rated health was investigated as a covariate in all models. Though somewhat more nuanced, the estimated trajectories for PA, NA, affect optimization, and poignancy provided support for theories of affective aging. The implications of these findings, directions for future research, and issues surrounding using cross-sectional data to infer developmental change are discussed. (PsycINFO Database Record

The impact of neural responses to food cues following stress on trajectories of negative and positive affect and binge eating in daily life

Stress and affect have been implicated in the maintenance of binge eating for women with symptoms of bulimia nervosa (BN). Neuroimaging and ecological momentary assessment (EMA) have separately examined how these variables may contribute to eating disorder behavior. Though both methodologies have their own strengths, it's unclear how either methodology might inform the other. This study examined the impact of individual differences in neural reactivity to food cues following acute stress on the trajectories of positive affect (PA) and negative affect (NA) surrounding binge eating. Women (n = 16) with BN symptoms viewed palatable food cues before and after a stress induction in the scanner. For two weeks, participants responded to prompts assessing affect and binge episodes several times a day. EMA data revealed NA increased and PA decreased before binge episodes in the natural environment. Additionally, NA decreased while PA increased following binge episodes. Changes in activation in the ACC, amygdala, and the vmPFC significantly moderated the relationship of affect to binge eating. However, lateral differences of each brain region uniquely moderator the trajectory of PA, NA, or both to binge eating. Specifically, those with less change in BOLD response reported significantly increasing NA and decreasing PA prior to binges, while women with greater decreases reported no change in affect. Following binge eating, individuals with decreased change in BOLD response reported decreasing NA and increasing PA. This may suggest individual differences in neural response to food cues under stress appear to underlie affect driven theory on the antecedents to binge eating.

Distinct trajectories of positive and negative affect after colorectal cancer diagnosis.

Insight into trajectories of positive affect (PA) and negative affect (NA) across the cancer continuum may improve understanding of the nature of adjustment problems. The primary aim of this study was to identify subgroups of patients with distinct trajectories of PA and NA following diagnosis of colorectal cancer (CRC). Secondary to this aim, the co-occurrence between trajectories and their association with goal-related processes was explored. CRC patients (n = 186) completed questionnaires within 1 month, 7 months, and 18 months after diagnosis. Multilevel models were used to study the trajectory of PA and NA, as measured with the Positive and Negative Affect Schedule (PANAS). Four classes with distinct PA trajectories were identified: low (18.8%), increasing (6.7%), moderate (68.2%), and high (6.3%); 2 trajectories of NA emerged: low (36.3%) and moderate (63.7%). There was no significant association between PA and NA trajectory class probabilities. The average trajectory of PA covaried with levels of goal disturbance and goal reengagement over time, while the average NA trajectory covaried with goal disturbance and goal disengagement. Compared with the general population, our sample of cancer patients suffered from a lack of positive emotions, but not a high presence of negative emotions. About one fifth of patients reported low PA up to 18 months after diagnosis and may benefit from supportive care. Furthermore, the trajectory of PA was independent of that of NA and related with a distinct goal adjustment process (i.e., goal disengagement vs. goal reengagement). This finding indicates the need to tailor psychological care to the nature of the adjustment problem. (PsycINFO Database Record

Acute exercise attenuates negative affect following repeated sad mood inductions in persons who have recovered from depression.

Identifying factors that may protect individuals from developing Major Depressive Disorder (MDD) in the face of stress is critical. In the current study we experimentally tested whether such a potentially protective factor, engaging in acute exercise, reduces the adverse effects of repeated sad mood inductions in individuals who have recovered from depression. We hypothesized that recovered depressed participants who engage in acute exercise report a smaller increase in negative affect (NA) and a smaller decrease in positive affect (PA) when exposed to a repeated sad mood induction (i.e., habituation), whereas participants who do not exercise show sensitization (i.e., increased NA and decreased PA in response to a repeated adverse stimulus). Forty-one women recovered from MDD and 40 healthy control women were randomly assigned to either exercise for 15 minutes or quiet rest. Afterward, participants were exposed to two sad mood inductions and reported their levels of affect throughout the study. Recovered depressed participants who had not exercised exhibited higher NA after the second sad mood induction, a finding consistent with sensitization. In contrast, both recovered depressed participants who had engaged in acute exercise and healthy control participants showed no increase in NA in response to the repeated sad mood induction. Participants who exercised reported higher PA after the exercise bout; however, our hypothesis concerning reported PA trajectories following the sad mood inductions was not supported. Results suggest that exercise can serve as a protective factor in the face of exposure to repeated emotional stressors, particularly concerning NA in individuals who have recovered from depression.

Trajectories of affective states in adolescent hockey players: Turning point and motivational antecedents.

This study examined longitudinal trajectories of positive and negative affective states with a sample of 265 adolescent elite hockey players followed across 3 measurement points during the 1st 11 weeks of a season. Latent class growth modeling, incorporating a time-varying covariate and a series of predictors assessed at the onset of the season, was used to chart out distinct longitudinal trajectories of affective states. Results provided evidence for 3 trajectories of positive affect and 3 trajectories of negative affect. Two of these trajectories were deflected by team selection, a seasonal turning point occurring after the 1st measurement point. Furthermore, the trajectories of positive and negative affective states were predicted by theoretically driven predictors assessed at the start of the season (i.e., self-determination, need satisfaction, athletic identity, and school identity). These results contribute to a better understanding of the motivational, social, and identity-related processes associated with the distinct affective trajectories of athletes participating in elite sport during adolescence.
