Development of narcissism across the life span: A meta-analytic review of longitudinal studies.

This meta-analytic review investigated the development of narcissism across the life span, by synthesizing the available longitudinal data on mean-level change and rank-order stability. Three factors of narcissism were examined: agentic, antagonistic, and neurotic narcissism. Analyses were based on data from 51 samples, including 37,247 participants.

Rank-order stability of domain-specific self-esteem: A meta-analysis.

This meta-analysis examined the rank-order stability of domain-specific self-esteem by comprehensively synthesizing the available evidence in eight domains of self-esteem (i.e., academic, appearance, athletic, morality, romantic, social, mathematics, and verbal abilities).

The structure of metacognition in middle childhood: Evidence for a unitary metacognition-for-memory factor.

It has been debated whether children's metacognitive monitoring and control processes rely on a general resource or whether metacognitive processes are task specific. Moreover, findings about the extent to which metacognitive processes are related to first-order task performance are mixed. The current study aimed to uncover the relationships among children's monitoring (discrimination between correct and incorrect responses), control (accurate withdrawal of wrong answers), and performance across three memory-based learning tasks: Kanji learning, text comprehension, and secret code learning.

How relationship satisfaction changes within and across romantic relationships: Evidence from a large longitudinal study.

Research suggests that relationship satisfaction changes in systematic ways over the course of a relationship. In this preregistered study, we tested whether relationship satisfaction changes differently as a function of the eventual outcome of the relationship, that is, whether the relationship lasted, whether it was dissolved, and whether people began a new relationship after separation. Data came from a large longitudinal study (the Longitudinal Study of Generations), including 2,268 participants aged 16-90 years, who were assessed at up to seven waves across 20 years.

Normative body image development: A longitudinal meta-analysis of mean-level change.

This meta-analysis synthesized longitudinal data on mean-level change in body image, focusing on the constructs of body satisfaction and dissatisfaction, body esteem, perceived attractiveness, valuation, self-objectification, and body shame. We searched five databases and accessed unpublished data to identify studies that assessed body image at two or more time points over six months or longer. Analyses were based on data from 142 samples representing a total of 128,254 participants.

Rank-order stability of relationship satisfaction: A meta-analysis of longitudinal studies.

Satisfaction with a romantic relationship often changes over time, and individuals differ in how satisfied they are in their relationship. However, no systematic review is available regarding the stability of individual differences in relationship satisfaction. Therefore, this meta-analysis synthesizes the available longitudinal data on rank-order stability of relationship satisfaction, as a function of age and relationship duration.

Effect size guidelines for cross-lagged effects.

Cross-lagged models are by far the most commonly used method to test the prospective effect of one construct on another, yet there are no guidelines for interpreting the size of cross-lagged effects. This research aims to establish empirical benchmarks for cross-lagged effects, focusing on the cross-lagged panel model (CLPM) and the random intercept cross-lagged panel model (RI-CLPM). We drew a quasirepresentative sample of studies published in four subfields of psychology (i.

Development of relationship satisfaction across the life span: A systematic review and meta-analysis.

Previous research has not led to any agreement as to the normative trajectory of relationship satisfaction. In this systematic review and meta-analysis, we summarize the available evidence on development of relationship satisfaction, as a function of age and relationship duration. Data came from 165 independent samples including 165,039 participants.

Vanishing Boycott Impetus: Why and How Consumer Participation in a Boycott Decreases Over Time.

Unlabelled: Media reports that a company behaves in a socially nonresponsible manner frequently result in consumer participation in a boycott. As time goes by, however, the number of consumers participating in the boycott starts dwindling. Yet, little is known on why individual participation in a boycott declines and what type of consumer is more likely to stop boycotting earlier rather than later.

Self-esteem and satisfaction with social relationships across time.

Research on the longitudinal association between self-esteem and satisfaction with social relationships has led to ambiguous conclusions regarding the temporal order and strength of this relation. Existing studies have examined this association across intervals ranging from days to years, leaving it unclear as to what extent differences in timing may explain differences across studies. In the present study, we used continuous time structural equation models (i.

Testing prospective effects in longitudinal research: Comparing seven competing cross-lagged models.

In virtually all areas of psychology, the question of whether a particular construct has a prospective effect on another is of fundamental importance. For decades, the cross-lagged panel model (CLPM) has been the model of choice for addressing this question. However, CLPMs have recently been critiqued, and numerous alternative models have been proposed.

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.

The policy relevance of personality traits.

Personality traits are powerful predictors of outcomes in the domains of education, work, relationships, health, and well-being. The recognized importance of personality traits has raised questions about their policy relevance, that is, their potential to inform policy actions designed to improve human welfare. Traditionally, the use of personality traits in applied settings has been predicated on their ability to predict valued outcomes, typically under the assumption that traits are functionally unchanging.

The link between self-esteem and social relationships: A meta-analysis of longitudinal studies.

Theorists have long assumed that people's self-esteem and social relationships influence each other. However, the empirical evidence has been inconsistent, creating substantial uncertainty about whether relationships are in fact an influential factor in self-esteem development and vice versa. This meta-analysis synthesizes the available longitudinal data on the prospective effect of social relationships on self-esteem (48 samples including 46,231 participants) and the prospective effect of self-esteem on social relationships (35 samples including 21,995 participants).

Family environment and self-esteem development: A longitudinal study from age 10 to 16.

In this study, we examined the effect of family environment on self-esteem development from late childhood (age 10) through adolescence (age 16), using 4-wave longitudinal data from 674 Mexican-origin families living in the United States. To assess family environment, a multi-informant approach was used (i.e.

Development of self-esteem from age 4 to 94 years: A meta-analysis of longitudinal studies.

To investigate the normative trajectory of self-esteem across the life span, this meta-analysis synthesizes the available longitudinal data on mean-level change in self-esteem. The analyses were based on 331 independent samples, including data from 164,868 participants. As effect size measure, we used the standardized mean change per year.

Uncovering the Power of Personality to Shape Income.

The notion of person-environment fit implies that personal and contextual factors interact in influencing important life outcomes. Using data from 8,458 employed individuals, we examined the combined effects of individuals' actual personality traits and jobs' expert-rated personality demands on earnings. Results from a response surface analysis indicated that the fit between individuals' actual personality and the personality demands of their jobs is a predictor of income.

Codevelopment of well-being and self-esteem in romantic partners: Disentangling the effects of mutual influence and shared environment.

Common sense suggests that romantic partners tend to be interdependent in their well-being and self-esteem. The authors tested the degree to which codevelopment in romantic partners (i.e.

Consumer lay theories on healthy nutrition: A Q methodology application in Germany.

Food is an important driver of individual health, and an important subject in public policy and health intervention research. Viewpoints on what constitutes healthy nutrition, however, are manifold and highly subjective in nature, suggesting there is no one-size-fits-all behavioral change intervention. This research explores fundamental lay theories regarding healthy nutrition with consumers in Germany.

Mutational analysis of the GLA gene in Mexican families with Fabry disease.

Fabry disease (FD) is a lysosomal storage disorder, which develops due to a deficiency in the hydrolytic enzyme, α-galactosidase A (α-Gal A). Alpha-Gal A hydrolyzes glycosphingolipid globotriaosylceramide (Gb3), and an α-Gal A deficiency leads to Gb3 accumulation in tissues and cells in the body. This pathology is likely to involve multiple systems, but it is generally considered to affect primarily vascular endothelium.
