Explicating narrow and broad conceptualizations of environmental influences on personality.

BACKGROUND: A surge of studies aims to identify environmental factors that explain individual differences, personality stability, and personality development. This special issue builds on this large interest and solicited articles on broad and narrow environmental factors of personality. OBJECTIVE: We provide an overview of the motivations behind the special issue, review each of the articles, and present data on researchers' perceptions of environmental factors contributing to personality expression and development. METHOD: We review 16 special issue articles, thematically grouped into seven topics-culture and race, genes and environment, geography and habitat, major/minor life events, social relationships, socioeconomic status and economic inequality, and work. We also present data on researchers' (N = 223) responses and ratings of environmental influences on personality expression and development. RESULTS: In the open-ended responses, the most important environmental influences were family, culture, peers, relationships, and trauma. Among the least important were weather, birth order, geography, climate, and shared environment. Nearly all the environmental influences featured in this special issue were considered at least somewhat important; however, there was considerable heterogeneity in how important researchers found each topic. CONCLUSIONS: There is no perfect consensus among researchers as to which environmental factors contribute most to personality expression and development. We hope that there is a larger surge of studies on personality constructs beyond traits, that contextualize concepts within a cultural and historical framework and develop more stringent theories to hypothesize about the environmental influences on personality.

The Perks of Pet Ownership? The Effects of Pet Ownership on Well-Being During the COVID-19 Pandemic.

Pet ownership has often been lauded as a protective factor for well-being, particularly during the COVID-19 pandemic. We expanded this question to consider how pet (i.e., species, number) and owner (i.e., pet relationship quality, personality, attachment orientations) characteristics affected the association between pet ownership and well-being in a pre-registered mixed method analysis of 767 people assessed three times in May 2020. In our qualitative analyses, pet owners listed both benefits and costs of pet ownership during the COVID-19 pandemic. In our quantitative analyses, we found that pet ownership was not reliably associated with well-being. Furthermore, this association largely did not depend on the number of pets owned, the species of pet(s) owned, the quality of the human-pet relationship, or the owner's psychological characteristics. Our findings are consistent with a large body of research showing null associations of pet ownership on well-being (quantitatively) but positive reports of pet ownership (qualitatively).

Trait and facet personality similarity and relationship and life satisfaction in romantic couples.

Previous research has shown that personality similarity plays a negligible role in explaining the life and relationship satisfaction of couples. However, similarity in more proximally measured personality (i.e., facets) might explain additional variance in partners' well-being. The current study examined if in a sample of 1294 female-male romantic couples individual and partner personality traits and facets were associated with life and relationship satisfaction in expected ways. Similarity in personality traits and facets was not robustly associated with either life or relationship satisfaction of partners. The results are discussed in the context of the predictive validity of personality facets.

Age and gender differences in narcissism: A comprehensive study across eight measures and over 250,000 participants.

Age and gender differences in narcissism have been studied often. However, considering the rich history of narcissism research accompanied by its diverging conceptualizations, little is known about age and gender differences across various narcissism measures. The present study investigated age and gender differences and their interactions across eight widely used narcissism instruments (i.e., Narcissistic Personality Inventory, Hypersensitive Narcissism Scale, Dirty Dozen, Psychological Entitlement Scale, Narcissistic Personality Disorder Symptoms from the Diagnostic and Statistical Manual of Mental Disorders, Version IV, Narcissistic Admiration and Rivalry Questionnaire-Short Form, Single-Item Narcissism Scale, and brief version of the Pathological Narcissism Inventory). The findings of Study 1 (N = 5,736) revealed heterogeneity in how strongly the measures are correlated. Some instruments loaded clearly on one of the three factors proposed by previous research (i.e., Neuroticism, Extraversion, Antagonism), while others cross-loaded across factors and in distinct ways. Cross-sectional analyses using each measure and meta-analytic results across all measures (Study 2) with a total sample of 270,029 participants suggest consistent linear age effects (random effects meta-analytic effect of r = -.104), with narcissism being highest in young adulthood. Consistent gender differences also emerged (random effects meta-analytic effect was -.079), such that men scored higher in narcissism than women. Quadratic age effects and Age × Gender effects were generally very small and inconsistent. We conclude that despite the various conceptualizations of narcissism, age and gender differences are generalizable across the eight measures used in the present study. However, their size varied based on the instrument used. We discuss the sources of this heterogeneity and the potential mechanisms for age and gender differences.

A test of the investment model among asexual individuals: The moderating role of attachment orientation.

Many asexual individuals are in long-term satisfying romantic relationships. However, the contributors to relational commitment among asexual individuals have received little attention. How do investment model characteristics and attachment orientations predict relationship commitment among asexual individuals? Our study looked at a sample of 485 self-identified asexual individuals currently in a romantic relationship (Mage = 25.61, SD = 6.24; MRelationshipLength = 4.42 years, SD = 4.74). Individuals reported on Investment Model characteristics (i.e., their relationship satisfaction, investment, alternatives, and commitment) and their attachment orientations. Satisfaction, investment, and fewer alternatives were associated with greater commitment. Attachment orientations only occasionally moderated the results: for people low in anxiety, satisfaction and investment were more strongly related to commitment compared to people high in anxiety. The current study provided an extension of the Investment Model to describe romantic relationships among asexual individuals.

Within-Couple Associations Between Communication and Relationship Satisfaction Over Time.

Relationship science contends that the quality of couples' communication predicts relationship satisfaction over time. Most studies testing these links have examined between-person associations, yet couple dynamics are also theorized at the within-person level: For a given couple, worsened communication is presumed to predict deteriorations in future relationship satisfaction. We examined within-couple associations between satisfaction and communication in three longitudinal studies. Across studies, there were some lagged within-person links between deviations in negative communication to future changes in satisfaction (and vice versa). But the most robust finding was for concurrent within-person associations between negative communication and satisfaction: At times when couples experienced less negative communication than usual, they were also more satisfied with their relationship than was typical. Positive communication was rarely associated with relationship satisfaction at the within-person level. These findings indicate that within-person changes in negative communication primarily covary with, rather than predict, relationship satisfaction.

The mirror's curse: Weight perceptions mediate the link between physical activity and life satisfaction among 727,865 teens in 44 countries.

PURPOSE: The present study aimed to examine the link between physical activity (PA) and life satisfaction in a large international study of adolescents. We also aimed to test whether overweight and underweight perceptions act as mediators and whether age and sex acted as moderators. METHODS: For this purpose, we analyzed data from the Health Behavior in School-aged Children study, which comprises 727,865 observations from 44 nations at 4 measurement occasions. RESULTS: Multilevel analyses revealed a positive link between PA and life satisfaction. In addition, underweight and overweight perceptions mediated the effect of PA on life satisfaction. We further found that age and sex acted as moderators. In older adolescents, stronger effects were found in the links between PA and life satisfaction, PA and overweight perception, and both weight perceptions and life satisfaction. In addition, in female adolescents, the link between overweight perception and life satisfaction was stronger. Conversely, the links between PA and both weight perceptions were stronger for boys. CONCLUSION: The results suggest that weight perception explains part of the relationship between PA and life satisfaction in adolescents and that these effects vary as a function of age and sex.

Interdependence of Approach and Avoidance Goals in Romantic Couples Over Days and Months.

OBJECTIVES: Despite the centrality of people's approach goals (i.e., approach toward positive outcomes) and avoidance goals (i.e., avoidance of negative outcomes) in romantic relationships, little is known about the interdependence of approach and avoidance relationship goals between partners. Assuming that short-term, state-level goals accumulate into general goal tendencies, the present research tested whether partners' daily (i.e., state level) and aggregated daily (i.e., trait level) approach and avoidance goals are mutually predictive in the short term (after one day) and the long term (after 10-12 months). In addition, we explored whether goal interdependence unfolds differently across adulthood and in relationships of different duration. METHOD: Approach and avoidance goals were assessed daily on two 14-day measurement-burst occasions that were conducted 10-12 months apart. The sample consisted of N = 456 female-male couples (age: M = 33.6, SD = 13.8 years; relationship duration: M = 9.6, SD = 10.7 years). RESULTS: We observed significant short- and long-term partner effects in the prediction of couple members' approach and avoidance goals. These partner effects were restricted to trait level and they did not emerge at the state level. Almost all effects were independent of age and relationship duration. DISCUSSION: The present research underscores the importance of disentangling state- and trait-level goal tendencies when investigating the interdependence of approach and avoidance goals within romantic relationships.

Until death do us part: The codevelopment of life satisfaction in couples preceding the death of one partner.

This work aims to integrate previous research perspectives on terminal well-being decline and partner bereavement by investigating the codevelopment of life satisfaction in the years preceding the death of one partner. We analyzed longitudinal data from the German Socio-Economic Panel Study (N = 1,450 couples) and applied dyadic multilevel models to estimate both partners' trajectories of life satisfaction and to reveal the pathways of well-being transmission in couple members approaching [partner] death. Findings were compared with a propensity-score-matched control sample of couples in which neither partner died during the study. We found that to-be-deceased and to-be-bereaved partners experienced increasing disparities in their trajectories of life satisfaction in the years before [partner] death: Although both partners exhibited significant and accelerated declines in life satisfaction, these declines were more pronounced in to-be-deceased individuals. In the control sample, we also identified significant and accelerated declines in life satisfaction but these declines were less intense and they did not differ between partners. Regarding between-partner correlations, we observed that couples approaching [partner] death experienced weaker interdependencies in their declines of life satisfaction. Finally, and concerning the pathways of well-being transmission, we found that life satisfaction was significantly transmitted between partners and the strength of this effect did not differ between the samples. These findings suggest that the years before [partner] death are characterized by distinctive patterns of change and interdependence in life satisfaction. Future studies may explore the sources of increasing between-partner disparities in life satisfaction in an end-of-life relationship context.

Assessing the ability of the Drug-Associated Risk Tool (DART) questionnaire to stratify hospitalised older patients according to their risk of drug-related problems: a cross-sectional validation study.

OBJECTIVES: The Drug-Associated Risk Tool (DART) has been developed as a self-administered questionnaire for patients with the aim of stratifying patients according to their risk of drug-related problems (DRPs). We aimed to validate the ability of the questionnaire to distinguish between hospitalised patients showing lower and higher numbers of DRPs. DESIGN: Cross-sectional study assessing the questionnaire's concurrent criterion validity. SETTING: Five geriatric and the associated physical and neurological rehabilitation wards of a Swiss regional secondary care hospital with 617 beds. PARTICIPANTS: We recruited 110 patients from a total of 437 admissions. Exclusion criteria were insufficient knowledge in spoken or written German, medical conditions preventing meaningful conversations and already receiving pharmacy services. INTERVENTIONS: Comprehensive pharmacist-led clinical medication reviews were performed, including patient interviews, to identify potential and manifest DRPs. A cluster analysis was conducted to assess the discriminatory potential of the DART to group patients according to number (low and high) of identified DRPs. A subsequent discriminatory function analysis was performed to reduce the number of items. We determined which DART items may be used to trigger what type of medication review. RESULTS: Recruited patients had a median age of 79 years and were prescribed a median of 11 drugs. Patients with a median DART score of 10 and a median of 3 DRPs represented one cluster, whereas patients with a median DART score of 15 and a median of 8 DRPs represented another cluster. Discriminatory function analysis reduced the questionnaire to five items with a moderate to strong correlation with the number of DRPs per patient (Spearman's rank correlation ρ=0.44). Additional items were associated with patients benefiting from interviews. CONCLUSIONS: As a self-administered questionnaire for patients, the DART may be used to stratify hospitalised non-acute older patients in groups of having low and high likelihood of DRPs. The analyses showed that a short form of the DART can be used instead of the full tool to identify older inpatients at risk for DRPs. Additional eight items from the DART may be used to initiate additional clinical pharmacy services. The linkage between certain DART questions and type of medication review enables pharmacist resource allocation.

The association of mothers' and fathers' insomnia symptoms with school-aged children's sleep assessed by parent report and in-home sleep-electroencephalography.

OBJECTIVE: Sleep plays an essential role for children's well-being. Because children's sleep is associated with parental sleep patterns, it must be considered in the family context. As a first aim of the present study, we test whether parental insomnia symptoms are related to children's in-home sleep-electroencephalography (EEG). Second, we examine the association between parental insomnia symptoms and maternal and paternal perception of children's sleep using actor-partner interdependence models. METHODS: A total of 191 healthy children enrolled in public school and aged 7-12 years took part in the study. Ninety-six were formerly very preterm born children. Children underwent in-home sleep-EEG, and parents reported children's sleep-related behavior by using the German version of the Children's Sleep Habits Questionnaire. Further, parents completed the Insomnia Severity Index to report their own insomnia symptoms. RESULTS: Maternal but not paternal insomnia symptoms were related to less children's EEG-derived total sleep time, more stage 2 sleep, less slow wave sleep, later sleep onset time, and later awakening time. Mothers' and fathers' own insomnia symptoms were related to their reports of children's bedtime resistance, sleep duration, sleep anxiety, night wakings, and/or daytime sleepiness. Moreover, maternal insomnia symptoms were associated with paternal reports of children's bedtime resistance, sleep anxiety, and sleep-disordered breathing. The associations between parental insomnia symptoms and parents' perception of children's sleep could not be explained by children's objectively measured sleep. CONCLUSIONS: Mothers' insomnia symptoms and children's objective sleep patterns are associated. Moreover, the parents' own insomnia symptoms might bias their perception of children's sleep-related behavior problems.

Testing Relations of Crystallized and Fluid Intelligence and the Incremental Predictive Validity of Conscientiousness and Its Facets on Career Success in a Small Sample of German and Swiss Workers.

This study examined the relation of fluid and crystallized intelligence with extrinsic (occupational skill level, income) and intrinsic (job satisfaction) career success as well as the incremental predictive validity of conscientiousness and its facets. Participants (N = 121) completed the Reynolds Intellectual Assessment Scales (RIAS), the Revised NEO Personality Inventory (NEO-PI-R), and reported their occupational skill level, income, and job satisfaction. Results revealed that crystallized intelligence was positively related to occupational skill level, but not to income. The association of crystallized intelligence and job satisfaction was negative and stronger for the lowest occupational skill level, whereas it was non-significant for higher levels. Fluid intelligence showed no association with career success. Beyond intelligence, conscientiousness and its facet self-discipline were associated with income, whereas conscientiousness and its facets competence and achievement striving were associated with job satisfaction. The results are discussed in terms of their implications for the assessment process as well as for future research to adequately predict career success.
