Persons in contexts: The role of social networks and social density for the dynamic regulation of face-to-face interactions in daily life.

Current psychological theories on daily social interactions emphasize individual differences yet are underspecified regarding contextual factors. We aim to extend this research by examining how two context factors shape social interactions in daily life: how many relationships people maintain and how densely people live together. In Study 1, 307 German participants (Mage = 39.44 years, SDage = 14.14) answered up to 20 experience sampling questionnaires regarding their social interactions over 2 days. In Study 2, 313 German participants (Mage = 48.96 years, SDage = 15.54) summarized their daily interactions in daily diaries for 14 days. Participants reported on their social network size and the social density (i.e., household and neighborhood density) of their living situations. Mobile sensing provided additional measures of social interactions and network size. The results showed that participants living in densely populated households transitioned faster from solitude to social interactions but slower from social interactions to solitude. Participants living in dwellings with more homes also transitioned slower from solitude to social interactions. Contrary to the hypothesis, social network size was inconsistently linked with transitions from solitude to social interactions and vice versa. Furthermore, current social desires predicted subsequent social interactions within days, but not across days-irrespective of individuals' social network size or social density. Together the results point out that people live their daily life in social contexts, which contribute to how they engage in social interactions. The findings thus call for a greater integration of contextual factors in personality theories of social interactions. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Social dynamics and affect: Investigating within-person associations in daily life using experience sampling and mobile sensing.

Social interactions are crucial to affective well-being. Still, people vary interindividually and intraindividually in their social needs. Social need regulation theories state that mismatches between momentary social desire and actual social contact result in lowered affect, yet empirical knowledge about this dynamic regulation is limited. In a gender- and age-heterogenous sample, German-speaking participants (N = 306, 51% women, Mage = 39.41, range 18-80 years) answered up to 20 momentary questionnaires about social interactions and affect while mobile sensing tracked their conversations, calls, and app usage over 2 days. Combining preregistered and exploratory analyses, we investigated how momentary affect relates to social dynamics, focusing on two states of mismatch between social desire and social contact: social deprivation (i.e., being alone but desiring contact) and social oversatiation (i.e., being in contact but desiring to be alone). We used specification curve analyses to scrutinize the operationalization of these constructs. Social oversatiation was associated with decreased positive affect and increased negative affect. Social deprivation, however, was unrelated to affect. Exploratory multilevel models showed that a higher desire to be alone was consistently associated with decreased affective well-being, whereas a higher desire for social contact was related to increased affective well-being. Mobile sensing data revealed differential association patterns between affect and face-to-face versus digital communication. We discuss implications for social need regulation, related studies on voluntary solitude, and advantages of combining experience sampling and mobile sensing assessments.

My virtual home: needs of patients in palliative cancer care and content effects of individualized virtual reality - a mixed methods study protocol.

BACKGROUND: The desire to be at home is one of the most important needs of patients with advanced, incurable cancers. However, palliative cancer patients may require inpatient hospital care for medical reasons. Virtual reality (VR) could provide an approximation to the individuals' home environment. METHODS: The project consists of 3 parts. All parts are supported by the patient advisory board. In the 1st part of the project, we interview patients, relatives, and the patient advisory board about their wishes and concerns regarding the project. In the 2nd part of the project, patients are offered to view 360° VR videos of their choice (their home, relatives, others if applicable). Effects and side-effects of the intervention are assessed with validated instruments (MIDOS, MDBF, SSQ, SPES). Diagnosis, treatment adherence, medication, and vegetative functionality is determined from the medical records of the patients. In the 3rd part of the project, the results of the study will be discussed with patients, relatives, health care professionals and the patient advisory board regarding implementation. DISCUSSION: This study is the first to investigate whether individualized VR videos have additional benefits over generic VR nature videos on symptom relief, well-being, treatment satisfaction, and adherence in patients with palliative cancer care. A strength of the study is that we can incorporate the results of each part of the project into the subsequent project parts. However, the generalizability might be limited as this is a single-centred study.

Interdependencies Between Family and Friends in Daily Life: Personality Differences and Associations with Affective Well-Being Across the Lifespan.

Family and friends are central to human life and well-being. Yet, interdependencies between family and friends have scarcely been examined. How is the relative frequency of daily contact with family and friends (i.e., the friends/family-ratio) related to personality and to well-being? In an experience sampling study with 396 participants (M age= 40 years, range 14-88 years, 52% females), we studied how the friends/family-ratio in contact differed along Big Five personality trait scores and was connected to affective well-being across six daily measurements on nine days (average of 55 assessments). Most participants reported more daily contact with family than friends (i.e. they held a family orientation), but individual differences were substantial. More agreeable individuals reported a greater family orientation. More extraverted individuals reported more positive affect in the company of friends than with family. Age moderated the effect of the friends/family-ratio on positive affect. Younger adults reported less positive affect in the company of family, yet older adults reported more positive affect in the company of family, the more they were friendship oriented. We discuss how examining the friends/family-ratio extends previous knowledge on personality differences in social relationships, and how the friends/family-ratio yields promising, yet challenging, future directions in personality-relationship associations.

Ecological Momentary Assessment: A Meta-Analysis on Designs, Samples, and Compliance Across Research Fields.

Ecological Momentary Assessments (i.e., EMA, repeated assessments in daily life) are widespread in many fields of psychology and related disciplines. Yet, little knowledge exists on how differences in study designs and samples predict study compliance and dropout-two central parameters of data quality in (micro-)longitudinal research. The current meta-analysis included k = 477 articles (496 samples, total N = 677,536). For each article, we coded the design, sample characteristics, compliance, and dropout rate. The results showed that on average EMA studies scheduled six assessments per day, lasted for 7 days, and obtained a compliance of 79%. Studies with more assessments per day scheduled fewer assessment days, yet, the number of assessments did not predict compliance or dropout rates. Compliance was significantly higher in studies providing financial incentives. Otherwise, design or sample characteristics had little effects. We discuss the implications of the findings for planning, reporting, and reviewing EMA studies.

Age and context effects in personality development: A multimethod perspective.

Observing most pronounced personality trait changes during young adulthood raises the question whether the traits are more stable per se after young adulthood or whether greater stability of daily life contexts also contributes to smaller trait changes in older adults. In this longitudinal multimethod study, we tested the competing explanations of trait stability and context stability by examining (a) whether age differences in Big Five trait changes are less pronounced when younger and older people experience similar context conditions, in this case, college life and (b) whether people of similar age change differently in different contexts. Furthermore, based on dual-process models of personality and because previous research has relied on self-ratings, we examined whether assumed personality changes also occur in implicit measures and other-ratings of traits. The sample of 241 adults consisted of older students (Mage = 67.5 years), older age- and education-matched nonstudents (Mage = 67.7 years), and young students (Mage = 21.1 years). We obtained self-ratings, other-ratings, and implicit measures of Big Five traits at four time points over 2 years. The results replicated increases in self-ratings of emotional stability, open-mindedness, extraversion, and conscientiousness in young first-year students and demonstrated distinct patterns of change among older students and older nonstudents. Changes in other-ratings and implicit measures only partly mirrored changes in self-ratings of Big Five traits. The study highlights the importance of different measures of traits to better understand personality development beyond self-ratings, and that in some groups, substantial trait changes are possible beyond young adulthood.

Bidirectional Links of Daily Sleep Quality and Duration With Pain and Self-rated Health in Older Adults' Daily Lives.

BACKGROUND: Sleep and health perceptions, such as self-ratings of pain and health are closely linked. However, the temporal ordering of such associations is not well understood, and it remains unclear whether sleep quality and sleep duration show similar or differential associations with health perceptions. METHODS: We used ecological momentary assessment data from 123 young-old (66-69 years, 47% women) and 47 old-old adults (84-90 years, 60% women). Across 7 consecutive days, participants reported their sleep quality and sleep duration each morning and rated their momentary pain and health 6 times per day. We applied dynamic structural equation models to examine bidirectional links of morning reports of sleep quality and duration with daily levels of self-rated pain and health. RESULTS: In line with the hypotheses, results showed that when participants reported better sleep quality than what is typical for them, they reported less pain and better self-rated health on the day that followed. Longer sleep duration was not linked with subsequent pain or self-rated health. On days when people rated their health as better than usual, they reported better sleep quality but not longer sleep duration the following night. These associations were not moderated by age, gender, or chronic pain. CONCLUSION: Findings suggest that in old age, sleep quality is more relevant for health perceptions than sleep duration. Associations between sleep quality and self-rated health seem to be bidirectional; daily pain was linked to prior but not subsequent sleep quality.

Valuing Negative Affect Weakens Affect-Health Linkages: Similarities and Differences Across Affect Valuation Measures.

Negative affect (NA) has been robustly linked to poorer psychological health, including greater depressive symptoms, personal burnout, and perceived stress. These associations, known as affect-health links, have been postulated by our research team to vary with different levels of negative affect valuation (NAV), such that people who evaluate NA states as more pleasant, helpful, appropriate, and/or meaningful may show weaker affect-health links. Another affect valuation construct is ideal NA, which is the degree to which people ideally want to experience NA states (i.e., desirability of affective states). The current study extends previous research by examining these two different measures of affect valuation (NAV and ideal NA) and comparing the extent to which they moderate affect-health links for psychological health and functioning. Participants from the Health and Daily Experiences (HEADE) study (N = 162 comprising of 56 younger adults and 106 older adults) completed questionnaires in a laboratory setting and ecological momentary assessments of NA 6 times a day for 7 consecutive days (i.e., trait NA). The results demonstrated that the two affect valuation constructs were distinct and showed different patterns of buffering effects. NAV attenuated the association between trait NA and depressive symptoms, personal burnout, and intolerance of uncertainty. Ideal NA attenuated affect-health links for depressive symptoms and perceived stress. These findings point to the importance of sharpening the distinctions between various affect valuation constructs to elucidate their unique contributions to attenuating affect-health links.

Preparing medical first responders for crises: a systematic literature review of disaster training programs and their effectiveness.

BACKGROUND: Adequate training and preparation of medical first responders (MFRs) are essential for an optimal performance in highly demanding situations like disasters (e.g., mass accidents, natural catastrophes). The training needs to be as effective as possible, because precise and effective behavior of MFRs under stress is central for ensuring patients' survival and recovery. This systematic review offers an overview of scientifically evaluated training methods used to prepare MFRs for disasters. It identifies different effectiveness indicators and provides an additional analysis of how and to what extent the innovative training technologies virtual (VR) and mixed reality (MR) are included in disaster training research. METHODS: The systematic review was conducted according to the PRISMA guidelines and focused specifically on (quasi-)experimental studies published between January 2010 and September 2021. The literature search was conducted via Web of Science and PubMed and led to the inclusion of 55 articles. RESULTS: The search identified several types of training, including traditional (e.g., lectures, real-life scenario training) and technology-based training (e.g., computer-based learning, educational videos). Most trainings consisted of more than one method. The effectiveness of the trainings was mainly assessed through pre-post comparisons of knowledge tests or self-reported measures although some studies also used behavioral performance measures (e.g., triage accuracy). While all methods demonstrated effectiveness, the literature indicates that technology-based methods often lead to similar or greater training outcomes than traditional trainings. Currently, few studies systematically evaluated immersive VR and MR training. CONCLUSION: To determine the success of a training, proper and scientifically sound evaluation is necessary. Of the effectiveness indicators found, performance assessments in simulated scenarios are closest to the target behavior during real disasters. For valid yet inexpensive evaluations, objectively assessible performance measures, such as accuracy, time, and order of actions could be used. However, performance assessments have not been applied often. Furthermore, we found that technology-based training methods represent a promising approach to train many MFRs repeatedly and efficiently. These technologies offer great potential to supplement or partially replace traditional training. Further research is needed on those methods that have been underrepresented, especially serious gaming, immersive VR, and MR.

Good night-good day? Bidirectional links of daily sleep quality with negative affect and stress reactivity in old age.

Bidirectional links between sleep quality and emotional experiences are complex and not yet well understood-especially in old age when substantial changes occur in sleep and emotional experiences. Because previous research rarely considered the role of stressors, we examine if older adults' sleep quality is directly associated with subsequent negative affect (NA) or more indirectly via affective reactivity to stressors. Specifically, we investigate whether and how older adults' sleep quality predicts negative affect and affective reactivity to stress on the following day, and vice versa. For seven consecutive days, 325 older adults (61-90 years, 49% women) reported their sleep quality each morning as well as momentary negative affect and stressful events multiple times a day. Results from multilevel structural equation models showed that after nights of lower sleep quality, older adults reported more negative affect, but not higher affective reactivity to stressors. In turn, after days with increased affective reactivity but not more negative affect, participants reported worse sleep quality. We discuss whether older adults are able to regulate the effects of low sleep quality, but have difficulties downregulating stress and its effects on sleep.

A developmental perspective on personality-relationship transactions: Evidence from three nationally representative samples.

OBJECTIVE: Throughout their lives, people experience different relationship events, such as beginning or dissolving a romantic relationship. Personality traits predict the occurrence of such relationship events (i.e., selection effects), and relationship events predict changes in personality traits (i.e., socialization effects), summarized as personality-relationship transactions. So far, evidence was partly inconsistent as to how personality traits and relationship events are linked with each other. In this article, we argue that unnoticed age differences might have led to these inconsistencies. To systematically test for age differences in transactions, we conceptualize relationship events in terms of gains and losses and apply a developmental perspective on transactions. METHODS: Using longitudinal data from three nationally representative samples (SOEP, HILDA, Understanding Society), we computed event-focused latent growth models and summarized the results meta-analytically. RESULTS: The findings indicated some transactions. Of these, selection effects were stronger than socialization effects, and effects of gain-based events were stronger than effects of loss-based events. We observed few interactions with age. CONCLUSION: Selection effects and, particularly, socialization effects, tend to be rare and fairly independent of age. We discuss a series of broader and narrower factors that may have an impact on the strength of transactions across adulthood.

The incremental validity of average states: A replication and extension of Finnigan and Vazire (2018).

States refer to our momentary thoughts, feelings, and behaviors. Average states (aggregates across multiple time points) are discussed as a more accurate and objective measure of personality compared to global self-reports since they do not only rely on people's general beliefs about themselves. Specifically, Finnigan and Vazire (2018) argued that, if average states better capture what a person is actually like, this should be reflected in their unique association with informant-reports of personality, and tested this idea based on two experience-sampling studies. Their results showed, however, that average self-reported states did not predict global informant-reported personality above and beyond global self-reports. In this research, we aimed at replicating and extending these results. We used data of five studies (total N = 806) that involved global self- and informant-reports and employed a variety of different experience-sampling methods (time-based with different sampling schedules, event-based). Across all studies, the original results (i.e., no incremental effects of average self-reported states) were replicated. Furthermore, as an extension to the original study, we found that average other-reported states (provided by peers, results based on one study) did indeed predict global informant-reports above and beyond global self-reports. These findings highlight the importance of differentiating between method effects (global reports vs. average states) from source of information effects (self vs. other). We discuss these results, focusing on the suitability of using informant-reports as a criterion variable and conceptual differences between assessment methods.

Stressors faced by healthcare professionals and coping strategies during the early stage of the COVID-19 pandemic in Germany.

BACKGROUND: The COVID-19 pandemic has exerted great pressure on national health systems, which have aimed to ensure comprehensive healthcare at all times. Healthcare professionals working with COVID-19 patients are on the frontline and thereby confronted with enormous demands. Although early reports exist on the psychological impact of the pandemic on frontline medical staff working in Asia, little is known about its impact on healthcare professionals in other countries and across various work sectors. The present cross-sectional, online survey sought to investigate common work stressors among healthcare professionals, their psychological stress as well as coping resources during the pandemic. METHODS: A sample of 575 healthcare professionals (57% male) in three different sectors (hospital, prehospital emergency care, and outpatient service) reported their experiences concerning work and private stressors, psychological stress, and coping strategies between April 17, 2020 and June 5, 2020. To capture pandemic-specific answers, most of the items were adapted or newly developed. Exploratory factor analyses (EFA) were conducted to detect underlying latent factors relating to COVID-specific work stressors. In a next step, the effects of these latent stressors across various work sectors on psychological stress (perceived stress, fatigue, and mood) were examined by means of structural equation models (SEM). To add lived experience to the findings, responses to open-ended questions about healthcare professionals' stressors, effective crisis measures and prevention, and individual coping strategies were coded inductively, and emergent themes were identified. RESULTS: The EFA revealed that the examined work stressors can be grouped into four latent factors: "fear of transmission", "interference of workload with private life", "uncertainty/lack of knowledge", and "concerns about the team". The SEM results showed that "interference of workload with private life" represented the pivotal predictor of psychological stress. "Concerns about the team" had stress-reducing effects. The latent stressors had an equal effect on psychological stress across work sectors. On average, psychological stress levels were moderate, yet differed significantly between sectors (all p < .001); the outpatient group experienced reduced calmness and more stress than the other two sectors, while the prehospital group reported lower fatigue than the other two sectors. The prehospital group reported significantly higher concerns about the team than the hospital group (p < .001). In their reports, healthcare professionals highlighted regulations such as social distancing and the use of compulsory masks, training, experience and knowledge exchange, and social support as effective coping strategies during the pandemic. The hospital group mainly mentioned organizational measures such as visiting bans as effective crisis measures, whereas the prehospital sector most frequently named governmental measures such as contact restrictions. CONCLUSION: The study demonstrated the need for sector-specific crisis measures to effectively address the specific work stressors faced by the outpatient sector in particular. The results on pandemic-specific work stressors reveal that healthcare professionals might benefit from coping strategies that facilitate the utilization of social support. At the workplace, team commitment and knowledge exchange might buffer against adverse psychological stress responses. Schedules during pandemics should give healthcare workers the opportunity to interact with families and friends in ways that facilitate social support outside work. Future studies should investigate cross-sector stressors using a longitudinal design to identify both sector- and time-specific measures. Ultimately, an international comparison of stressors and measures in different sectors of healthcare systems is desirable.

A domain-differentiated approach to everyday emotion regulation from adolescence to older age.

Flexibly using different emotion-regulation (ER) strategies in different situational contexts, such as domains, has been argued to promote effective emotion regulation. Additionally, emotion regulation processes may change with age as narrowing time horizons shift emotion-regulation preferences. The purpose of the present study was to examine the occurrence and effectiveness of flexible emotion regulation in response to daily hassles from different domains within the age range from adolescence to old age. Participants, ranging from 14 to 88 years old (N = 325), completed an experience-sampling study of approximately 9 days over a 3-week period. At each momentary assessment, participants reported on their hassles, emotion-regulation strategies, and affect. As expected, strategy use varied across individuals and domains. For example, emotion expression and suppression were typical responses to interpersonal hassles, whereas social sharing was often used in response to work/school hassles. In situations wherein hassles included multiple life domains, participants reported the use of more emotion-regulation strategies than for single-domain hassles. Although flexible emotion regulation was evident in participants' responses to hassles, the expectation that it would be associated with lower hassle reactivity was not confirmed. These patterns were, for the most part, consistent across ages. This study contributes new insights into situational characteristics that are associated with emotion-regulation flexibility, showing that hassles domains are important for strategy selection, and that this holds from adolescence to old age. It also suggests that such defined emotion-regulation flexibility is not as strongly linked to emotion-regulation effectiveness as has been previously suggested.

Between-person and within-person associations of sleep and working-memory in the everyday lives of old and very old adults: initial level, learning, and variability.

STUDY OBJECTIVES: Sleep duration affects various aspects of cognitive performance, such as working-memory and learning, among children and adults. However, it remains open, whether similar or even stronger associations exist in old and very old age when changes in sleep and cognitive decrements are common. METHODS: Using repeated daily-life assessments from a sample of 121 young-old (66-69 years old) and 39 old-old adults (84-90 years old), we assessed links between sleep duration and different aspects of working-memory (initial level, practice-related learning, and residualized variability) between and within persons. Participants reported their sleep durations every morning and performed a numerical working-memory updating task six times a day for seven consecutive days. RESULTS: Both people who slept longer and those who slept shorter than the sample average showed lower initial performance levels, but a stronger increase of WM over time (i.e. larger learning effects), relative to people with average sleep. Sleep duration did not predict performance variability. Within-person associations were found for people sleeping relatively little on average: For them, working-memory performance was lower on days with shorter than average sleep, yet higher on days with longer than average sleep. Except for lower initial levels of working-memory in old-old adults, no differences between young-old and old-old adults were observed. CONCLUSION: We conclude that sufficient sleep remains important for working-memory performance in older adults and that it is relevant to include different aspects of working-memory performance, because effects differed for initial performance and learning.

The role of extraversion and neuroticism for experiencing stress during the third wave of the COVID-19 pandemic.

Although long postulated, it has been scarcely researched how personality traits play out differently in distinct situations. We examined if Neuroticism and Extraversion, personality traits known to moderate stress processes, function differently in highly stressful situations requiring reduced social contact, that is, the COVID-19 pandemic. Based on past findings, we expected neuroticism to be associated with exacerbated perceptions of stress. In contrast to past findings, we expected extraversion, which usually ameliorates stress, to be associated with intensified perceptions of stress, especially in regard to the sociability facet. During the third wave of the COVID-19 pandemic in Germany, one-hundred-thirty adults (age M = 21.7 years) reported on their personality traits including their facets with the BFI-2, COVID-19-related stressors, and their perceived stress during the last month (using the PSS). Findings indicated that neuroticism was associated with higher perceived stress regardless of the COVID-19-related stressors experienced. Facet level analysis revealed differences for anxiety, depression, and volatility. Importantly, trait extraversion was unassociated with stress experiences, whereas specifically the facet of sociability was associated with higher perceived stress. Also, the facets of assertiveness and energy both moderated the relationship between COVID-19-related stressors and perceived stress. In line with the transactional theory of stress, our findings indicate that perceptions of stress were best understood by looking at the interaction of environmental stressors and personality differences. Furthermore, the study substantiates that facets of personality traits offer unique information beyond broad traits in specific contexts.

Longitudinal coupling of momentary stress reactivity and trait neuroticism: Specificity of states, traits, and age period.

Personality traits like neuroticism show both continuity and change across adolescence and adulthood, with most pronounced changes occurring in young adulthood. It has been assumed, but insufficiently examined, that trait changes occur gradually over the years through the accumulation of daily experiences. The current longitudinal measurement burst study examined (a) how changes in average momentary stress reactivity are coupled with changes in trait neuroticism, (b) the extent to which this coupling is specific to stress reactivity and neuroticism, and (c) the extent to which there are age differences in the association between changes in stress reactivity and changes in neuroticism. Participants (N = 581; 50% male) between 14 and 86 years of age completed up to 3 waves (T1-T3) of Big Five trait questionnaires and experience-sampling assessments during 6 years. During each three-week experience-sampling period, participants reported their momentary affect and occurrences of hassles on average 55 times. Latent change models showed that increases over time in affective reactivity to daily hassles were associated with increases in neuroticism. This effect was consistent from T1 to T2 as well as from T2 to T3, and most pronounced in young adulthood. Importantly, the results were specific to associations between stress reactivity and neuroticism because changes in frequency of hassles in daily life did not predict changes in neuroticism, and stress reactivity did not consistently predict changes in the other Big Five traits. The findings help to inform theoretical models that outline how short-term states might contribute to gradual longer-term changes in traits like neuroticism.

Stability and Change in Diffusion Model Parameters over Two Years.

In recent years, mathematical models of decision making, such as the diffusion model, have been endorsed in individual differences research. These models can disentangle different components of the decision process, like processing speed, speed-accuracy trade-offs, and duration of non-decisional processes. The diffusion model estimates individual parameters of cognitive process components, thus allowing the study of individual differences. These parameters are often assumed to show trait-like properties, that is, within-person stability across tasks and time. However, the assumption of temporal stability has so far been insufficiently investigated. With this work, we explore stability and change in diffusion model parameters by following over 270 participants across a time period of two years. We analysed four different aspects of stability and change: rank-order stability, mean-level change, individual differences in change, and profile stability. Diffusion model parameters showed strong rank-order stability and mean-level changes in processing speed and speed-accuracy trade-offs that could be attributed to practice effects. At the same time, people differed little in these patterns across time. In addition, profiles of individual diffusion model parameters proved to be stable over time. We discuss implications of these findings for the use of the diffusion model in individual differences research.

Daily life processes predict long-term development in explicit and implicit representations of Big Five traits: Testing predictions from the TESSERA (Triggering situations, Expectancies, States and State Expressions, and ReActions) framework.

This study examined daily life processes and their contribution to long-term continuity and change in explicit and implicit representations of Big 5 traits. The TESSERA framework (Wrzus & Roberts, 2017) served as theoretical background to derive predictions on 3 linked research questions (RQ) regarding (a) trait-state associations (RQ1); (b) antecedents and consequences of personality states (RQ2); as well as (c) processes of personality development (RQ3). We assessed Big 5 traits using self-ratings (i.e., BFI-44) and implicit association tests 4 times across 2 years in a sample of 382 younger (Mage = 21.57 years) and older (Mage = 67.76 years) adults. We also assessed momentary processes in multiple waves of daily diaries (total M = 43.9 days) focusing on people's most memorable daily experience. As predicted in RQ1, all self-rated traits, and implicit associations of self with conscientiousness, agreeableness, or emotional stability predicted subsequent trait-relevant situations and states. Regarding RQ2 across all trait domains, momentary processes could be generalized as sequences of Triggering situations, Expectancies, States and State Expressions, and ReActions (i.e., TESSERA sequences). With respect to RQ3, states were associated with long-term changes in self-rated conscientiousness and agreeableness, and self-rated and implicitly measured extraversion. Our findings further support the assumption that momentary experiences in daily life can contribute to long-term Big 5 changes, and extend previous research by examining implicit self-concepts and changes therein. The findings highlight the role of triggering situations, expectancies, reactions, and reflection in personality development in addition to trait-relevant states.

Why stop at two opinions? Reply to McCrae (2020).

McCrae (2020) argues that it is premature to explore interventions focused on personality change. In his commentary, he suggests that interventions should be promoted only if their effects in self-report data are confirmed by the additional opinion of informants. We agree with the essence of his position and would go further by envisioning a new framework for rigorous collaborative research on personality change (Bleidorn et al., 2020). We nevertheless maintain that policymakers would benefit from considering the additional opinion of personality scientists. (PsycInfo Database Record (c) 2020 APA, all rights reserved).
