Ovulatory cycle shifts in human motivational prioritisation of sex and food.

Previous research on the endogenous effects of ovarian hormones on motivational states in women has focused on sexual motivation. The Motivational Priority Shifts Hypothesis has a broader scope. It predicts a shift from somatic to reproductive motivation when fertile. In a highly powered preregistered online diary study across 40 days, we tested whether 390 women report such an ovulatory shift in sexual and eating motivation and behaviour. We compared 209 naturally cycling women to 181 women taking hormonal contraceptives (HC) to rule out non-ovulatory changes across the cycle as confounders. We found robust ovulatory decreases in food intake and increases in general sexual desire, in-pair sexual desire and initiation of dyadic sexual behaviour. Extra-pair sexual desire increased mid-cycle, but the effect did not differ significantly in HC women, questioning an ovulatory effect. Descriptively, solitary sexual desire and behaviour, dyadic sexual behaviour, appetite, and satiety showed expected mid-cycle changes that were diminished in HC women, but these failed to reach our strict preregistered significance level. Our results provide insight into current theoretical debates about ovulatory cycle shifts while calling for future research to determine motivational mechanisms behind ovulatory changes in food intake and considering romantic partners' motivational states to explain the occurrence of dyadic sexual behaviour.

Character strength traits, states, and emotional well-being: A daily diary study.

OBJECTIVE: Does whole trait theory work for character strengths? This study examines the daily within- and between-person variability of the manifestations of positively valued lower-order personality characteristics, namely character strengths, their convergence with trait character strengths, and their relationships to daily measures of affect. BACKGROUND: Manifestations of personality traits vary both between- and within people. So far, research has focused on between-person differences in character strengths, while within-person differences have been neglected. METHODS: German-speaking participants (N = 199, 84.3% women; mean age = 26.0 years) participated in a two-week daily diary study. They completed a baseline measure of character strength traits and daily measures of character strength states and positive and negative affect. RESULTS: Results suggested that character strength traits converged well with aggregated states. Further, we observed high within-person variability in most character strengths. The trait-state convergence and the amount of within-person variability were predicted by whether the character strengths were rather phasic (i.e., more dependent on situational characteristics) or rather tonic (i.e., less dependent on situational characteristics). Higher within-person variability in character strengths was related to trait levels of perspective, honesty, social intelligence, and fairness. Regarding relationships between character strengths and affect, within-person associations were widely parallel to previously reported between-person associations and largely independent of trait levels of character strengths. CONCLUSION: These findings inform research on whole trait theory and character-strengths-based interventions.

Older adults' subjective aging perceptions, mentalization, and social relationships: a micro-longitudinal study.

OBJECTIVES: Social relationships are associated with various positive physical, psychological, and emotional outcomes in older adults. In line with the growing understanding of the role of subjective views of aging (VoA) for older adults' quality of life, the current work examines how daily fluctuations in VoA affect social relationships. Moreover, as the ability to mentalize others' states of mind (i.e. Theory of Mind) considerably enhances such relationships, this study assesses whether mentalization abilities mediate the VoA-social relationships link. METHOD: Eighty-two Israeli older adults (mean age = 73.44, SD = 8.64, range = 60-95) completed a baseline online questionnaire containing background information, and subsequently filled out daily online questionnaires assessing ageist attitudes, subjective age, mentalization abilities, and positive social relationships for 14 consecutive days. RESULTS: Positive VoA (reduced ageist attitudes and/or a young subjective age) were associated with enhanced mentalization and positive relationships on a given day and in time-lagged analyses. Moreover, mentalization mediated the effect of previous-day VoA on next-day positive social relationships. VoA also mediated the effect of previous-day mentalization on next-day positive social relationships. CONCLUSION: The study highlights the importance of mentalization capabilities for maintaining positive VoA/social relationships and expands the understanding of underlying factors associated with meaningful and close relationships in older adults.

Overall team justice and psychological strain: A daily diary study.

Drawing on the relational and uncertainty models of justice, this research investigates the consequences of daily overall team justice perceptions on employees' daily psychological strain. Specifically, we examine daily psychological safety as a mediator of the relationship between daily overall team justice evaluations and daily psychological strain. We also argue that daily overall supervisor justice moderates this mediated relationship. Using a daily diary study over 10 consecutive working days, our results confirm that daily team justice reduces employees' daily psychological strain. In addition, our findings provide evidence that daily psychological safety mediates the effects of daily justice perceptions on daily psychological strain. Results also show that the relationship between daily overall team justice and daily psychological safety is moderated by overall supervisor justice, thereby complementing the target similarity model.

How Families Make Their Way Into Your Heart: Exploring the Associations Between Daily Experiences Involving Family Members and Cardiovascular Health.

BACKGROUND: Cardiovascular disease is a critical public health issue and a growing body of literature on relationships and health point to individuals' interactions and involvement with family members as significant correlates of cardiovascular outcomes. However, less is known about the implications of daily encounters with family members on cardiovascular health outcomes and how the associations vary across adulthood. PURPOSE: The aims of this study were to examine the associations of positive and negative daily experiences with family members with comprehensive measures of cardiovascular health and to further explore how age moderates these associations. METHODS: This study used data from the Midlife in the United States (MIDUS) II and MIDUS Refresher. The sample was composed of respondents who participated in two subprojects of MIDUS, namely the National Study of Daily Experiences (NSDE) and Biomarker Project (N = 1,312). Indices of cardiovascular health included inflammatory markers, autonomic functioning, and Life's Simple 7 scores. RESULTS: Results showed that the associations between daily family experiences and cardiovascular outcomes differed by age. Having more daily negative experiences with family members was associated with better cardiovascular health outcomes among young adults and worse cardiovascular outcomes among older adults. Having more daily positive experiences was also associated with lower heart rate variability for older adults. CONCLUSIONS: Results revealed that contrary to the general assumption that negative experiences have health-damaging effects, frequent involvement with family members in daily life, even negative ones, may be indicative of active engagement in life that could be health promoting for younger adults.

Adolescent psychological adjustment and social supports during pandemic-onset remote learning: A national multi-wave daily-diary study.

In spring 2020, U.S. schools universally transitioned to online learning due to the COVID-19 pandemic's onset, thus creating a natural experiment for examining adolescents' risk and resilience during an ongoing school crisis response. This longitudinal study used a daily-diary approach to investigate the role of social support in the link between remote learning and psychological well-being across 64 days among a national sample of adolescents (n = 744; 42% Black, 36% White, 22% Other ethnicity/race; 41% boys; 72% eligible for free/reduced-priced lunch; Mage=14.60, SDage=1.71, age-range = 12-17 years). On days when youth attended remote learning, they reported lower daily positive affect, more daily stress, and higher parent social support. There were no significant differences in the effect of remote learning on affect or stress by race or economic status. On days when youth experienced more parent support, they reported lower daily stress and negative affect and higher daily positive affect. On days when youth experienced more peer support, they reported higher daily positive affect. Overall, the study highlights the impact of pandemic-onset remote learning on adolescents' psychological well-being and emphasizes the need for future research on school crisis contingency planning to address these challenges.

A daily diary study on stressors, hurt feelings, aggression, and somatic symptoms: The role of rejection sensitivity and negative emotion differentiation.

The current study adopted a daily diary design to examine associations of daily stressors and hurt feelings to three unfavorable daily outcomes, including verbal aggression, physical aggression, and somatic symptoms and the moderation of rejection sensitivity and negative emotion regulation on the relations between these daily variables. A total of 248 college students participated in the daily diary study in which they responded to the assessment on a daily basis for 7 consecutive days. The results indicated that daily stressors predicted daily verbal aggression; daily stressors, daily hurt feelings, and rejection sensitivity predicted somatic symptoms. Negative emotion regulation moderated the association between stressors and verbal aggression such that more stressors and high negative emotion regulation predicted more frequent daily verbal aggression. Rejection sensitivity moderated the association of hurt feelings to verbal and physical aggression. Perception of hurt feelings and high rejection sensitivity predicted more verbal aggression but less physical aggression. Rejection sensitivity also moderated the association of stressors to somatic symptoms such that more stressors and high rejection sensitivity predicted more somatic symptoms. The findings collectively highlight the importance of supporting individuals with high rejection sensitivity to encode social cues in a healthy way. It is imperative to provide emotion regulation skills to cope with negative emotions derived from social interactions.

Adolescents' Love Lives: Heterogeneity in Relationship Status Trajectories and Links with Affect.

Romantic experiences are more fluid and heterogeneous during middle adolescence than at any other life stage, but current understanding of this heterogeneity and flux is limited because of imprecise measurement. A sample of 531 adolescents (55% female; 28% non-Hispanic White; 32% Black; 27% Hispanic; 14% Other) recruited from an ongoing birth cohort study (Mean age = 16.7 years, SD = 0.358), was administered bi-weekly diaries over 52 weeks to prospectively record transitions in and out of romantic and sexual relationships and to assess links with positive affect (frequency of happiness) and negative affect (frequency of sadness). Relationship statuses considered included not only dating, but also liminal and asymmetrical statuses such as talking/flirting and crushes. Latent profile analyses revealed six relationship status trajectories, or love life profiles, based on the number of intra-year partners and on the extent of involvement in each of the relationship statuses. Approximately half of teens either were in stable dating relationships or uninvolved romantically during the year; however, half experienced variable levels of flux in their love lives. Relationship instability, not romantic involvement per se, was associated with higher levels of sadness and lower levels of happiness. Snapshots of teen romantic involvement based on one or two points in time obscure the extent of relationship heterogeneity and flux and how relationship status trajectories are associated with positive and negative affect.

Who helped yesterday will help tomorrow: Trait and state components in prosocial goal realisation.

The present study aims to disentangle the state and trait components of prosocial goal realisation, defined as a set of personally meaningful prosocial actions undertaken in natural settings. Based on a diary study with seven daily measurements from 180 participants (a total of 1005 data points), we performed temporal variance decomposition using the STARTS model. The observed individual scores are explained by: ST-a common trait factor, capturing variance stable across days; ART-a unique autoregressive trait factor, capturing variance changing from 1 day to the next; and S-state factors, a series of uncorrelated factors reflecting occasion-specific variance. The results demonstrate the relative stability of prosocial goal realisation, extending the knowledge on the state/trait distinction in actual prosocial behaviour.

A Weekly Diary Study on Playful Study Design, Study Engagement, and Goal Attainment: The Role of Proactive Personality.

Students' learning processes are heavily impeded by the COVID-19 pandemic. Students are experiencing more online learning environment and less face-to-face idea exchange, which may make them feel exhausted and demotivated. Using self-determination and proactivity theories, we propose and examine whether playful study design (PSD)-a proactive study strategy including designing fun and designing competition in learning tasks-is effective in fostering study engagement, which, in turn, improves study goal attainment during the COVID-19 period. Moreover, we examine whether students who are high in proactive personality will benefit more (e.g., reach a higher level of study engagement) when using the PSD strategy. We collected data using a weekly diary approach during four consecutive weeks, including 97 people and 308 within-person observations. Results of multilevel analyses showed that weekly PSD was positively related to weekly study engagement, and in turn, facilitated weekly goal attainment. Moreover, we found that proactive personality moderated and strengthened the positive associations between PSD and goal attainment, study engagement and goal attainment, but not for the relationship between PSD and study engagement. Overall, we provide one of the first attempts to demonstrate how PSD strategy can be used in student study life to improve study engagement and reach their goals. We shed light on how proactive personality can safeguard the success of PSD strategy. Theoretical and practical contributions are discussed.

Vocal-Stress Diary: A Longitudinal Investigation of the Association of Everyday Work Stressors and Human Voice Features.

The human voice conveys plenty of information about the speaker. A prevalent assumption is that stress-related changes in the human body affect speech production, thus affecting voice features. This suggests that voice data may be an easy-to-capture measure of everyday stress levels and can thus serve as a warning signal of stress-related health consequences. However, previous research is limited (i.e., has induced stress only through artificial tasks or has investigated only short-term or extreme stressors), leaving it open whether everyday work stressors are associated with voice features. Thus, our participants (111 adult working individuals) took part in a 1-week diary study (Sunday until Sunday), in which they provided voice messages and self-report data on daily work stressors. Results showed that work stressors were associated with voice features such as increased speech rate and voice intensity. We discuss theoretical, practical, and ethical implications regarding the voice as an indicator of psychological states.

Anticipating the direction of symptom progression using critical slowing down: a proof-of-concept study.

BACKGROUND: As complex dynamic systems approach a transition, their dynamics change. This process, called critical slowing down (CSD), may precede transitions in psychopathology as well. This study investigated whether CSD may also indicate the direction of future symptom transitions, i.e., whether they involve an increase or decrease in symptoms. METHODS: In study 1, a patient with a history of major depression monitored their mental states ten times a day for almost eight months. Study 2 used data from the TRAILS TRANS-ID study, where 122 young adults at increased risk of psychopathology (mean age 23.64±0.67 years, 56.6% males) monitored their mental states daily for six consecutive months. Symptom transitions were inferred from semi-structured diagnostic interviews. In both studies, CSD direction was estimated using moving-window principal component analyses. RESULTS: In study 1, CSD was directed towards an increase in negative mental states. In study 2, the CSD direction matched the direction of symptom shifts in 34 individuals. The accuracy of the indicator was higher in subsets of individuals with larger absolute symptom transitions. The indicator's accuracy exceeded chance levels in sensitivity analyses (accuracy 22.92% vs. 11.76%, z=-2.04, P=.02) but not in main analyses (accuracy 27.87% vs. 20.63%, z=-1.32, P=.09). CONCLUSIONS: The CSD direction may predict whether upcoming symptom transitions involve remission or worsening. However, this may only hold for specific individuals, namely those with large symptom transitions. Future research is needed to replicate these findings and to delineate for whom CSD reliably forecasts the direction of impending symptom transitions.

How is the life without unicorns? A within-individual study on the relationship between uncertainty and mental health indicators: The moderating role of neuroticism.

The pandemic crisis of COVID-19 led to higher levels of uncertainty for individuals. Mental health has been outlined as a major key research priority to support and inform interventions. This study aimed to examine whether uncertainty influenced negative affect which in turn, resulted in worst levels of mental health, during the COVID-19 pandemic crisis, and test if neuroticism moderated the negative effect of uncertainty on mental health, via negative affect. To capture changes in daily uncertainty, negative affect and mental health, a daily design was adopted to test our model. We collected data through five consecutive days (N = 320), in the early "lockdown" stage of the pandemic. The multilevel results showed a significant mediation effect from daily uncertainty to daily mental health via daily negative affect. In addition, neuroticism moderated the mediated relationship, in such a way that the relationship between daily uncertainty on daily mental health, via daily negative affect was strengthened when neuroticism was higher. In sum, living without unicorns, or see the world though a black lens, is a factor that enhances the blackness of uncertainty.

Adolescents' Partner Search in the Digital Age: Correlates and Characteristics of Relationships Initiated Online.

Digital technology and social media platforms have transformed the ways adolescents communicate and cultivate romantic relationships, but few studies consider whether relationships initiated online are less salutary than those formed in person. A sample of 531 adolescents (Mean age = 16.7 years, SD = 0.358; 55% female) was recruited from an ongoing birth cohort study and administered bi-weekly diaries over a year to evaluate the circumstances associated with adolescents' romantic relationship formation and relationship quality. Two-thirds of respondents initiated one or more romantic relationships during the study, of which 15% were initiated online. Girls who did not fit in well at school and who had difficulty making friends were more likely to initiate romantic relationships online than their more sociable peers who fit in well at school; for boys, however, access to mobile devices increased the odds that romantic relationships were initiated online. The diaries captured considerable flux in the evolution of romantic relationships, but there was limited evidence that relationships initiated online involved greater risks, with the notable exception of greater age asymmetry.

Leading in times of crisis: How perceived COVID-19-related work intensification links to daily e-mail demands and leader outcomes.

The COVID-19 crisis brought numerous challenges to work life. One of the most notable may be the acceleration of digital transformation, accompanied by an intensification of e-mail usage and related demands such as high e-mail workload. While research quickly started to examine the implications of these changes for employees, another important group of stakeholders has been overlooked: leaders. We focus on leaders during the COVID-19 crisis and examine how COVID-19-related work intensification links to leaders' e-mail overload appraisal and finally exhaustion and transformational leadership, a leader behaviour especially needed in times of crisis. In a 5-day diary study in September 2020, 84 leaders responded to daily surveys on 343 days. Results of multilevel analysis showed that perceived COVID-19-related work intensification was positively linked to worktime spent dealing with e-mail and appraised e-mail overload. E-mail overload appraisal was positively related to leaders' exhaustion, but unrelated to their transformational behaviour. Day-specific time spent dealing with e-mail, however, was negatively related to transformational leadership. E-mail overload appraisal mediated the relationship between COVID-19-related work intensification and exhaustion. Turning the focus on leaders during the COVID-19 crisis, our study has important implications for the design of work of leaders in times of crisis and beyond.

Employees' fear at work, job crafting, and work engagement on a daily basis: The case for fear of COVID-19.

In the present study, we seek to understand how public sector employees that go to work to perform essential duties for the society and the economy cope with the fear of COVID-19 and maintain their motivation, energy, and enthusiasm for their work. We hypothesized that because employees are motivated to protect their health, an increase in daily fear of COVID-19 would be related to a daily increase in coping behaviors in the form of job crafting, which would consequently be related to employees' daily motivation. Data were based on 64 tenured employees working in public service organizations during the third wave of the COVID-19 pandemic (March 2021), who completed a quantitative diary for five consecutive workdays (N = 320 occasions). Results from multilevel analysis indicated that fear of COVID-19 had an indirect effect on work engagement through only one dimension of job crafting, seeking job resources. The study contributes to the ongoing theoretical extension of the beneficial role of job crafting by suggesting seeking social resources as an effective coping strategy for fear of COVID-19.

Hospital nurses experiencing day-to-day workplace incivility: A diary study on the benefits of daily social support.

AIM: The present study investigated the adverse effects of daily experienced incivility and the positive role of daily social support during the workday in predicting daily emotional exhaustion after work and vitality and positive affect at bedtime. BACKGROUND: Despite the broad knowledge of the impact of experienced incivility in different occupations, little is known about day-to-day nurse incivility, much less in the hospital context. METHOD: After completing a general questionnaire, hospital nurses (n = 96) completed a diary questionnaire twice a day for five consecutive workdays (n = 480 diary observations). The diary design had two levels: 5-day repeated measures (Level 1, day level) nested in persons (Level 2, person level) using an experience-sampling methodology. RESULTS: Multilevel hierarchical analyses showed that incivility during the workday increased emotional exhaustion after work (t = 3.00, p = <0.05) and reduced vitality (t = -2.48, p = 0.05) and positive affect (t = -2.23, p = 0.05) at bedtime. However, daily social support during the workday was a crucial job resource that directly benefited hospital nurses' daily wellbeing (t = 5.19, p = 0.01 vitality; t = 4.89, p = 0.01 positive affect) and buffered the adverse effects of daily workplace incivility (t = -2.33, p = 0.05). CONCLUSION: The within-person approach of our findings suggests that supportive practices can reduce day-to-day incivility spirals. IMPLICATIONS FOR NURSING MANAGEMENT: Nurse managers can promote a civility culture within their units using in service training programmes at work.

How and when goal-oriented self-regulation improves college students' well-being: A weekly diary study.

This study investigates how (i.e., through what mechanism) and when (i.e., under what conditions) goal-oriented self-regulation behaviors improve college students' psychological well-being. On the basis of data from 74 s-year Chinese college students in a weekly diary study (296 observations), we conducted a moderated mediation model and found that goal-oriented self-regulations behaviors (i.e., planning, monitoring, controlling, and reflecting) were positively related to college students' psychological well-being through increased academic performance. Further, such an indirect effect was stronger when college students' optimism and social support were high. This study contributes to student development and self-regulation literature by underscoring that academic performance plays a vital intermediate role in the relationship between self-regulation behaviors and college students' psychological well-being. Besides, we highlight that optimism and social support act as important personal and social resources for college students that can better unleash the positive effects of goal-oriented self-regulation behaviors.

Video connecting families and social robots: from ideas to practices putting technology to work.

Technology use is a socially embedded process, especially when it comes to older adults and care. However, the restrictions associated with the COVID-19 pandemic have limited social contact to protect vulnerable groups in care homes, and even if technology use has increased in other areas, there is little known about the potential uptake of communication technology and changes in social interaction in the care context during a lasting crisis. This paper explores changes in communication technology use triggered by the pandemic at two care homes, using a qualitative diary study, online interviews and observations, and in-situ interviews within the care home with residents and workers. Our findings point to increasing use of tablets and video conference software triggered by COVID-related experiences, with implications for living and working in care homes. We also characterise the isolation experience of the residents, the workers' concerns about the residents and changes in social interaction. We observed new areas of technology usage, associated changing work practices, technical affinity issues and context-specific attitudes towards future technologies. While the pandemic has triggered the use of communication technology in care homes on a small scale, this has also caused increasing workload and in particular articulation work, which requires support structures and the re-definition of work roles.

Discrepancy in Dyadic Sexual Desire Predicts Sexual Distress over Time in a Community Sample of Committed Couples: A Daily Diary and Longitudinal Study.

In long-term relationships, sexual desire discrepancy (SDD) occurs frequently between partners. For many, this discrepancy is persistent and significant, and a source of distress. However, the dynamics of SDD in couples and, specifically, its implications for sexual distress have received scant empirical attention. This study examined the associations between SDD and sexual distress from one day to the next and over a 12-month span, in a community sample of 229 same-sex/gender and mixed-sex/gender couples. Two datasets were collected: A 35-day daily diary and a 12-month longitudinal survey. In both, dyadic sexual desire and sexual distress were measured, and SDD was calculated as the absolute value of the difference in sexual desire between partners. Directional associations between SDD at one time point and sexual distress at the next time point were assessed using multilevel, 2-pane autoregressive cross-lagged models, controlling for within-variable changes, dependencies between partners, and partner age. Results were consistent with the study's hypotheses: Couples' SDD on one day predicted sexual distress on the next day. Similarly, SDD at baseline predicted sexual distress 12 months later. Participant gender, partner gender, and couple type did not significantly moderate these associations, nor did differentiating partners based on higher and lower average sexual desire. The reverse associations (i.e., sexual distress predicting SDD) were non-significant. The associations' directionality and the fact that they remained significant over days and months were consistent with the proposal that SDD is a precursor of sexual distress. The present study provides support for dyadic conceptualizations of sexual desire. Clinically, findings suggest that therapeutic approaches should address issues with sexual desire and sexual distress by focusing not on the individual, but on the couple.
