The effect of rebranding generic medicines on drug efficacy and side effects

Objectives: Subjective age is an important correlate of health, well-being, and longevity. So far, little is known about short-term variability in subjective age and the circumstances under which individuals feel younger/older in daily life. This study examined whether (a) older adults’ felt age fluctuates on a day-to-day basis, (b) daily changes in health, stressors, and affect explain fluctuations in felt age, and (c) the daily associations between felt age and health, stressors, or affect are time-ordered.

Method: Using an eight-day daily diary approach, N = 43 adults (60–96 years, M = 74.65, SD = 8.19) filled out daily questionnaires assessing subjective age, health, daily stressors, and affect. Data were analysed using multilevel modelling.

Main outcome measures: Subjective age, health, daily stressors, affect.

Results: Intra-individual variability in felt age was not explained by time but by short-term variability in other variables. Specifically, on days when participants experienced more than average health problems, stress, or negative affect they felt older than on days with average health, stress, or negative affect. No time-ordered effects were found.

Conclusion: Bad health, many stressors, and negative affective experiences constitute circumstances under which older adults feel older than they typically do. Thus, daily measures of subjective age could be markers of health and well-being.     

Passion and mindfulness: Accessing adaptive self-processes

The goal of this research was to examine passion as a determinant of mindfulness. Three studies were conducted based on the premise that harmonious passion (HP) provides access to adaptive self-processes, such as mindfulness, whereas obsessive passion (OP) limits such access. In Study 1 (n = 301), results revealed that HP and OP positively and negatively predicted mindfulness, respectively. Study 2 (n = 459) aimed at replicating results from Study 1 and explored the mediating role of mindfulness in the passion–affect relationship. Results uncovered that HP and OP, respectively, predicted positively and negatively mindfulness that, in turn, positively predicted positive affect and negatively predicted negative affect. These results were replicated in Study 3 (n = 176) while incorporating a time lag in the design. Vitality was also included in the model and was positively predicted by mindfulness. Findings underscore the facilitative role of HP in accessing adaptive self-processes, such as mindfulness.     

The effect of contemplation and meditation on ‘great compassion’ on the psychological well-being of adolescents

This study aimed to evaluate the effect of contemplation and meditation (CM) training, with a focus on developing great compassion, on the psychological well-being (PWB) of adolescents. Participants (N = 51, mean age = 15.8) were randomly allocated to either CM training (n = 26) or a comparison group (n = 25). Both groups completed measures of PWB before and after the intervention. Adolescents who received CM training showed statistically significant increases in environmental mastery and personal growth, as well as decreased negative affect compared to the comparison group. Girls in the experimental group also showed a significant decrease in negative affect compared with boys in the experimental group. Both the experimental and comparison groups demonstrated increased life satisfaction, environmental mastery, self-acceptance, autonomy, and purpose in life. There were no changes in positive affect and positive relations with others for both groups.     

Variability in affective change among aging men: Longitudinal findings from the VA Normative Aging Study

We examined change in both positive and negative affect over ages 45 to 97 among 1534 men (mean age = 69 years). Positive affect demonstrated a linear decline with age, while negative affect declined until approximately 70 years, and thereafter showed a gradual increase. Results indicated significant individual differences in rates of change for both positive and negative affect. We then examined whether personality, health, and work status might account for individual differences in levels and rates of change in affect. Higher extraversion was associated with higher levels of positive affect, but not with rate of change. Higher neuroticism predicted higher levels of negative affect, as well as an attenuated decline in middle-adulthood, and a steeper increase in later adulthood. Better health was associated with higher levels of positive affect and lower levels of negative, but was also found to predict less decline in negative affect. Work predicted lower levels of positive affect and higher levels of negative affect, as well as greater declines in positive affect. These findings indicate that individuals differ in the manner in which they change in affect over time.     

The effects of daily co-occurrence of affect on older adults’ reactivity to health stressors

Objectives: The present study examined age differences among older adults in the daily co-occurrence of affect and its potential role in buffering the negative effects of health stressors.

Design: Participants were from the Veterans Affairs Normative Aging Study and included 249 young-old adults (age = 60–79 years, M = 71.6) and 64 old-old adults (age = 80–89, M = 82.9) who completed questionnaires assessing stressors, physical health symptoms, and positive and negative affect for eight consecutive days.

Results: An independent samples t-test showed young-old and old-old adults did not significantly differ in their mean levels of daily co-occurrence of affect. The between-person relationships among stressors, health and daily co-occurrence of affect revealed that neither stressors nor health were significantly related to daily co-occurrence of affect. However, results from a multilevel model revealed a three-way cross-level interaction (health stressor × age group × co-occurrence of affect) where old-old adults with higher levels of co-occurrence of affect were less emotionally reactive to health stressors than young-old adults.

Conclusion: These findings provide support for the assertion that co-occurrence of affect functions in an adaptive capacity and highlight the importance of examining domain-specific stressors.     

Eveningness Predicts Negative Affect Following Sleep Restriction

Although considerable research has shown that sleep loss results in decreased positive affect, findings regarding change in negative affect are inconsistent. Such inconsistency may be due in part to variability in individual difference factors, such as chronotype, which is associated with both sleep and affective outcomes. Chronotype represents the tendency to be a morning- or evening-type person and is underpinned by the timing of circadian processes linked to sleep and mental health. The present study examined the predictive effect of chronotype above and beyond that of depression on affective response to sleep restriction in a sample of healthy sleeping adults (n = 73). Participants completed measures of chronotype and depression at baseline and measures of positive and negative affect before and after one night of sleep restriction (4 hours between 4 a.m. and 8 a.m.). Results indicate a large, significant decrease in positive affect following sleep restriction, but no statistically significant change in negative affect. Subsequent analyses showed that chronotype predicted affective response to sleep restriction, such that eveningness predicted a medium, significant increase in negative affect following sleep restriction, controlling for depression—however, there was no association between chronotype and change in positive affect in response to sleep restriction. These findings highlight a differential effect of sleep loss on positive and negative affect and suggest that evening chronotype may confer a distinct vulnerability for increased negative affect following sleep loss.     

Everyday creative activity as a path to flourishing

Recent experience sampling and diary studies have shown that spending time on creative goals during a day is associated with higher activated positive affect (PA) on that day. Based on models of creativity as a tool for promoting well-being, the present study examined cross-day relationships between creative activity, affect, and flourishing. A large sample of young adults (n = 658) took part in a 13-day daily diary study. Each day, they reported how much time they spent on creative activities, daily positive and negative affect, and daily flourishing. Lagged multilevel models revealed that people felt higher activated PA and flourishing following days when they reported more creative activity than usual. The other direction – PA predicting next-day creative activity – was not supported, suggesting that the cross-day effect was specific to creative activity predicting well-being. Overall, these findings support the emerging emphasis on everyday creativity as a means of cultivating positive psychological functioning.     

The differential similarity of positive and negative information – an affect-induced processing outcome?

People judge positive information to be more alike than negative information. This good-bad asymmetry in similarity was argued to constitute a true property of the information ecology (Alves, H., Koch, A., & Unkelbach, C. (2017). Why good is more alike than bad: Processing implications. Trends in Cognitive Sciences, 21, 69–79). Alternatively, the asymmetry may constitute a processing outcome itself, namely an influence of phasic affect on information processing. Because no research has yet tested whether phasic affect influences perceived similarity among stimuli, we conducted 5 Experiments that also tested whether phasic affect can account for the higher judged similarity among positive compared to negative stimuli. In three experiments, we affectively charged pictures of different Pokemon by pairing them with monetary gains and losses (Exp. 1a, 1b) as well as positive and negative trait words (Exp. 2); yet, the evaluative charge did not differentially influence perceived similarity among the Pokemon. Experiment 3 replicated the basic similarity asymmetry among positive and negative words, and found that it was unaffected by externally induced phasic affect. Experiment 4 showed that phasic affect had no influence on perceived similarity of non-evaluative words either. We conclude that albeit a weak influence of phasic affect on perceived similarity of stimuli cannot be ruled out entirely, it can most likely not account for the typically medium to large sized asymmetry in similarity among positive and negative stimuli.     

Feeling bad about progress does not lead people want to change their health behaviour

Objective: When do people decide to do something about problematic health behaviours? Theoretical models and pragmatic considerations suggest that people should take action when they feel bad about their progress – in other words, when they experience negative progress-related affect. However, the impact of progress-related affect on goal striving has rarely been investigated.

Design and Methods: Study 1 (N = 744) adopted a cross-sectional design and examined the extent to which measures of progress-related affect were correlated with intentions to take action. Study 2 (N = 409) investigated the impact of manipulating progress-related affect on intentions and behaviour in an experimental design.

Results: Study 1 found that, while engaging in health behaviours had the expected affective consequences (e.g. people felt bad when they were not eating healthily, exercising regularly or limiting their alcohol consumption), it was feeling good rather than bad about progress that was associated with stronger intentions. Study 2 replicated these findings. Participants induced to feel good about their eating behaviour had marginally stronger intentions to eat healthily than participants led to feel bad about their eating behaviour.

Conclusion: The findings have implications for interventions designed to promote changes in health behaviour, as well as theoretical frameworks for understanding self-regulation.     

Daily Affect and Intimacy in Emerging Adult Couples

We investigated individual- and couple-level associations between daily intimacy and affective states (N = 2211 observations) in 20 heterosexual emerging adult couples (age 18–25 years, M = 23) who had been in a sexual relationship with one another for at least 3 weeks (M = 12 months). Individual analyses revealed that emerging adults’ feelings of intimacy varied from day to day and that there were no gender differences in daily intimacy. Affect and intimacy were positively associated within day for women, but not for men. Time-lagged individual-level analyses revealed that prior-day positive or negative affect did not predict present-day intimacy for men or women. However, prior-day intimacy positively predicted present-day positive affect in men and negatively predicted present-day negative affect in women. Time-lagged couple-level analyses revealed that men’s prior-day positive affect positively predicted their female partner’s present-day intimacy. Women’s prior-day intimacy negatively predicted their male partner’s present-day negative affect. Implications of the day-to-day associations of intimacy with positive and negative affect within emerging adult couples are discussed.     

The effect of meaningfulness and integrative processing in expressive writing on positive and negative affect and life satisfaction

Meaningfulness and integrative processing of expressive writing may influence the effect of expressive writing. Participants completed measures of positive affect, negative affect and life satisfaction before and after an expressive writing intervention. Participants were randomly assigned to one of four expressive writing instruction conditions, which combined higher and lower levels of meaning and integrative processing instructions. Meaningfulness and integrative processing instructions had significant effects in increasing positive affect and there was a significant interaction between meaningfulness instructions and integrative processing instructions; participants in the high meaningfulness and high integrative processing instruction condition showed the greatest increase in positive affect. Meaningfulness had a significant effect in decreasing negative affect. The intervention did not influence life satisfaction. Both meaningfulness and integrative processing instructions led to more self-reported personal meaningfulness of the writing and more cognitive, emotional, behavioural and situational changes. More self-reported meaningfulness of the writing and more cognitive, emotional, behavioural and situational changes made as a result of the writing were in turn associated with greater increases in positive affect. The results of the study affirm the importance of meaningfulness and processing in expressive writing and potentially provide information regarding how to increase the effectiveness of expressive writing.     

Looking forward to tomorrow: The buffering effect of a daily optimism intervention

This research demonstrates the effectiveness of a brief daily self-applied optimism intervention in an adult normal population. Participants completed Life Orientation Test-Revised, Positive and Negative Affect Scale, Satisfaction with Life Scale, and Burnout Measure scales before, immediately after, and one month after the intervention. At baseline, optimism intervention group (N = 36) and control group (N = 41) were statistically similar on the variables of interest. At post-test, and also one month later, the intervention group demonstrated reduced pessimism, negative affect, and emotional exhaustion, although optimism, positive affect, and life satisfaction did not increase. Higher initial optimism increased the intervention effect for the optimism group, but not for the control group, by diminishing negative affect and emotional exhaustion, and increasing optimism. Sixty-one percent of the activities mentioned by the control group participants focused on duties and work, compared to 28% in the optimism condition. No correlations were found between initial optimism or pessimism, and the type of activities mentioned.     

Transactional development of parent personality and child temperament

Stability and change in parental extraversion and neuroticism were studied in transaction with their views of their child's temperament from the age of six months to the age of five‐and‐a‐half years in 109 mother–father–child triads (parent–daughter: n = 61, parent–son: n = 48). While parental traits showed high stability, infants' higher positive affectivity predicted an increase in parental extraversion over 5 years, and infant's higher activity predicted a decrease in parental neuroticism. Parent‐rated temperament showed expected heterotypic continuity. Initially higher parental extraversion predicted an increase in the child's effortful control, and higher parental neuroticism predicted an increase in the child's negative affectivity. The results indicate that parental personality and child temperament develop in transaction promoting change in each other. Copyright © 2008 John Wiley & Sons, Ltd.     

Positive affect mediates the relationships between resilience,social support and posttraumatic growth of women with infertility

This study aims to explore the relationship between resilience, social support, positive affect and posttraumatic growth among Chinese women with infertility, and to examine the mediating role of positive affect. A convenience sample of 1733 women diagnosed with infertility was recruited from the infertility outpatient clinics at three reproductive hospitals in Shandong Province of China between May 2015 and April 2016. They completed a background questionnaire, the Posttraumatic Growth Inventory, the Perceived Social Support Questionnaire, the Connor-Davidson Resilience Scale, the Positive and Negative Affect Schedule. Individuals reported high levels of PTG (M = 64.81; SD = 16.20). Perceived social support (β = .11, p < .001), resilience (β = .18, p < .001) and positive affect (β = .46, p < .001) were related to PTG. Positive affect may play a mediating role in the relationships between resilience (.125, .201, p < .001), social support (.055, .121, p < .001) and PTG. This study examines the effects of resilience, social support, and positive affect on PTG among Chinese infertile women. Wherein, positive affect may play a mediating role in the relationships between resilience, social support and PTG.     

The relationship of coping and its perceived effectiveness to positive and negative affect in sport

This article examined the ability of six different coping strategies and their perceived effectiveness in predicting positive and negative affect in sport. Furthermore, it was investigated whether perceived coping effectiveness moderated the influence of coping strategies on affect. British University athletes (N = 356) were requested to recall a recent important competition in their sport when they had a stressful or challenging experience. They were then asked to rate the extent to which they relied on a number of different coping strategies to deal with the situation and the degree to which they found these effective. In agreement with the theoretical predictions of Folkman (1984), problem-focused coping predicted positive affect whereas emotion-focused coping predicted negative affect. Furthermore, for almost all the coping variables, their perceived effectiveness predicted, in a positive way, positive affect and negatively, negative affect. Moreover, the perceived effectiveness of the coping strategies of seeking social support, venting of emotions, and behavioural disengagement, moderated the influence of those strategies on affect. Lastly, a comparison between high and low effective coping groups showed that the former was associated with more pleasant affective experiences.     

It’s good to do good and receive good: The impact of a ‘pay it forward’ style kindness intervention on giver and receiver well-being

Despite the popularity of the ‘pay it forward’ (PIF) concept in textbooks and popular culture, to date, no study has tested the effectiveness of a brief, one-time PIF activity on the well-being of those who do good and those who receive good. To test this, 83 undergraduates (‘givers’) performed random kind acts for 1.5 h. PIF resulted in a wide range of well-being benefits for givers (e.g. greater positive and lower negative affect), with females showing greater positive affect benefits. Receivers of kindness (N = 1014) also benefited as evidenced by greater smiling behavior and more sincere smiles vs. controls (N = 251). Of the 48 receivers who completed a follow-up online questionnaire, the majority indicated that they would also PIF, with almost 40% indicating that they already had. Results indicate that a one-time brief PIF intervention can have broad benefits for those involved.     

Reciprocal within-day associations between incidental affect and exercise: An EMA study

Previous research suggests that how people feel throughout the course of a day (i.e. incidental affect) is predictive of exercise behaviour. A mostly separate literature suggests that exercise can lead to more positive incidental affect.

Objective: This study examines the potential reciprocal effects of incidental affect and exercise behaviour within the same day.

Design: Fifty-nine low-active (exercise <60 min/week), overweight (BMI: 25.0–39.9) adults (ages 18–65) participated in a six-month print-based exercise promotion programme.

Main outcome measures: Ecological momentary assessment was used to record self-reported exercise sessions in real time and incidental affective valence (feeling good/bad) as assessed by the 11-point Feeling Scale at random times throughout the day.

Results: Use of a within-subjects cross-lagged, autoregressive model showed that participants were more likely to exercise on days when they experienced more positive incidental affect earlier in the day (b = .58, SE = .10, p < .01), and participants were more likely to experience more positive incidental affect on days when they had exercised (b = .26, SE = .03, p < .01), with the former association significantly stronger than the latter (t = 23.54, p < .01).

Conclusion: The findings suggest a positive feedback loop whereby feeling good and exercising are reciprocally influential within the course of a day.     

Creative at Each Age: Age‐Related Differences in Drivers of Workplace Creativity from an Experience Sampling Study

Creativity and innovation are essential agents for change processes and accelerating technical development. Having to face challenges, such as demographic change, organizations require individuals who are creative and innovative at each age. Previous research identified affect as a crucial determinant of creativity, even though empirical findings showed inconsistencies. Drawing on literature on age‐related changes in affective experiences, we investigated the moderating effect of employees’ age on the association between daily positive and negative affect and creativity using a daily diary study. A total of 116 employees responded to daily questionnaires twice a day over five consecutive working days. As expected, hierarchical linear modeling analyses revealed differential effects regarding the affect‐creativity association, dependent on employees’ age. Although older employees were most creative on days when they experienced a high level of positive affect (compared to their mean level of positive affect), younger employees were particularly creative when experiencing negative affect (compared to their mean level of negative affect). We discuss practical implications on how organizations could provide creativity‐enhancing work environments for employees at each age.     

Emotion regulation strategies in daily life: mindfulness,cognitive reappraisal and emotion suppression

Most empirical studies of emotion regulation have relied on retrospective trait measures, and have not examined the link between daily regulatory strategies and every day emotional well-being. We used a daily diary methodology with multilevel modelling data analyses (n = 187) to examine the influence of three emotion regulation strategies (mindfulness, cognitive reappraisal and emotion suppression) on the experience of daily negative and positive affect. Our results suggested that daily mindfulness was associated with lower negative and higher positive affect whereas the converse pattern was found for daily emotion suppression; cognitive reappraisal was related to daily positive, but not negative affect. When daily mindfulness, suppression and reappraisal were included in the same models, these strategies predicted unique variance in emotional well-being. Random slope analyses revealed substantial variability in the utility of these strategies. Indeed the presumably “adaptive” cognitive reappraisal strategy seemed to confer no benefit to the regulation of negative affect in approximately half the sample. Additional analyses revealed that age moderates the effect of cognitive reappraisal on daily negative affect: Higher use of reappraisal was associated with more negative affect for adolescents (aged 17 to 19) but became associated with less negative affect with increasing age. We interpret these results in line with a contextual view of emotion regulation where no strategy is inherently “good” or “bad”.     

Relation of positive memory recall count and accessibility with post-trauma mental health

ABSTRACT

Positive memory encoding and retrieval deficits have an empirical relation with several post-trauma outcomes. Drawing from the Contractor et al. model, we examined relations between positive memory characteristics and post-trauma mental health indicators. A trauma-exposed community sample of 203 participants (M_age?=?35.40 years; 61.10% female) was recruited via Amazon's Mechanical Turk. Participants completed measures of posttraumatic stress disorder (PTSD; PTSD Checklist for DSM-5), depression (Patient Health Questionnaire-9), posttraumatic cognitions (Posttraumatic Cognitions Inventory), affect (Positive and Negative Affect Schedule), count/number of recalled specific positive memories (Autobiographical Memory Test) and accessibility of a specific positive memory (i.e., subjective ease of recalling details of a memory; Memory Experiences Questionnaire-Short Form). Linear regression results indicated that PTSD intrusion severity, PTSD negative alterations in cognitions and mood (NACM) severity, PTSD alterations in arousal and reactivity (AAR) severity, self-blame, and positive affect significantly and negatively predicted the count of specific positive memories. Further, PTSD NACM severity, PTSD AAR severity, negative cognitions about the self, and negative affect significantly and negatively predicted accessibility of a specific positive memory. Thus, count/accessibility of specific positive memories was associated with several post-trauma mental health indicators; this highlights the relevance and potential impact of integrating positive memories into trauma treatment.
