Life satisfaction around the world: Measurement invariance of the Satisfaction With Life Scale (SWLS) across 65 nations, 40 languages, gender identities, and age groups.

The Satisfaction With Life Scale (SWLS) is a widely used self-report measure of subjective well-being, but studies of its measurement invariance across a large number of nations remain limited. Here, we utilised the Body Image in Nature (BINS) dataset-with data collected between 2020 and 2022 -to assess measurement invariance of the SWLS across 65 nations, 40 languages, gender identities, and age groups (N = 56,968). All participants completed the SWLS under largely uniform conditions.

Detecting jingle and jangle fallacies by identifying consistencies and variabilities in study specifications - a call for research.

Over the past few years, more attention has been paid to jingle and jangle fallacies in psychological science. Jingle fallacies arise when two or more distinct psychological phenomena are erroneously labeled with the same term, while jangle fallacies occur when different terms are used to describe the same phenomenon. Jingle and jangle fallacies emerge due to the vague linkage between psychological theories and their practical implementation in empirical studies, compounded by variations in study designs, methodologies, and applying different statistical procedures' algorithms.

Baseline trait mindfulness moderates the efficacy of mindfulness interventions and active controls: A meta-analysis of 177 randomised controlled trials.

Previous evidence suggests that benefits of mindfulness-based interventions (MBIs) may depend on individuals' baseline trait mindfulness (BTM) levels. This meta-analysis investigated moderating effects of BTM on changes in mental health outcomes and trait mindfulness in randomised controlled trials (RCTs) of MBIs. A total of 177 primary studies (total N = 13,486), comparing the treatment effects of MBIs against active, treatment-as-usual (TAU) and waitlist control groups, were synthesised via three-level meta-analysis.

Day-to-day associations between mindfulness and perceived stress: insights from random intercept cross-lagged panel modeling.

Objective: Mindfulness is frequently seen as a protective factor of stress, but self-report measures of mindfulness may overlap with other related constructs, such as mental health, and could thus not only be a predictor, but also an outcome of stress. This study thus aimed to examine the longitudinal bidirectional associations between the use and perceived helpfulness of the four mindfulness facets Observe, Describe, Nonjudge, and Nonreact with daily perceived stress.

Methods: Participants from a large ( = 1,276) mixed student and community group sample filled out a brief daily diary over the time span of 7 days.

Positive self-beliefs mediate the association between body appreciation and positive mental health.

Previous work has supported direct, positive associations between body appreciation and positive mental health, but has largely neglected to examine possible indirect mechanistic pathways. Here, we propose one relevant mediational pathway, wherein body appreciation is associated with positive mental health via positive self-beliefs (i.e.

Measurement-Invariant Fluid Anti-Flynn Effects in Population-Representative German Student Samples (2012-2022).

Generational IQ test scores in the general population were observed to increase over time (i.e., the Flynn effect) across most of the 1900s.

The Influence of Age, Gender and Education on Neuropsychological Test Scores: Updated Clinical Norms for Five Widely Used Cognitive Assessments.

Background: Sociodemographic effects (i.e., age, gender, education) have been shown to influence neuropsychological test scores.

The fraternal birth-order effect as a statistical artefact: convergent evidence from probability calculus, simulated data, and multiverse meta-analysis.

The fraternal-birth order effect (FBOE) is a research claim which states that each older brother increases the odds of homosexual orientation in men an immunoreactivity process known as the maternal immune hypothesis. Importantly, older sisters supposedly either do not affect these odds, or affect them to a lesser extent. Consequently, the fraternal birth-order effect predicts that the association between the number of older brothers and homosexual orientation in men is greater in magnitude than any association between the number of older sisters and homosexual orientation.

Body appreciation around the world: Measurement invariance of the Body Appreciation Scale-2 (BAS-2) across 65 nations, 40 languages, gender identities, and age.

The Body Appreciation Scale-2 (BAS-2) is a widely used measure of a core facet of the positive body image construct. However, extant research concerning measurement invariance of the BAS-2 across a large number of nations remains limited. Here, we utilised the Body Image in Nature (BINS) dataset - with data collected between 2020 and 2022 - to assess measurement invariance of the BAS-2 across 65 nations, 40 languages, gender identities, and age groups.

Are Speeded Tests Unfair? Modeling the Impact of Time Limits on the Gender Gap in Mathematics.

When cognitive and educational tests are administered under time limits, tests may become speeded and this may affect the reliability and validity of the resulting test scores. Prior research has shown that time limits may create or enlarge gender gaps in cognitive and academic testing. On average, women complete fewer items than men when a test is administered with a strict time limit, whereas gender gaps are frequently reduced when time limits are relaxed.

Support for weight-related anti-discrimination laws and policies: Modelling the role of attitudes toward poverty alongside weight stigma, causal attributions about weight, and prejudice.

In the present study, we sought to position support for weight-related anti-discrimination laws and policies within a broader political and socioeconomic context. Specifically, we hypothesised that individualistic (rather than structural) anti-poverty attitudes would provide the basis for negative weight-related dispositions. To test this hypothesis, we asked 392 respondents from the United Kingdom to complete measures of support for weight-related anti-discrimination laws and policies, attributions about the causes of being larger-bodied, and weight-related stigma and prejudice.

Bosnian Paternal War Orphans: Mental Health in Postwar Time.

More research on the medium- and long-term effects of childhood exposure to war, including orphanhood, is needed. We compared 50 orphans 1 who lost their father during the war in Bosnia and Herzegovina (1992-1995) and 50 age- and sex-matched adolescents from two-parent families during 2011-2012 in terms of sociodemographic characteristics, behavioral/emotional problems, depression, resilience, maternal mental health, and perceived social support. The two groups differed on sociodemographic factors, that is, number of children, family composition, income, school grades, and refugeehood.

Only Small Effects of Mindfulness-Based Interventions on Biomarker Levels of Inflammation and Stress: A Preregistered Systematic Review and Two Three-Level Meta-Analyses.

Mindfulness-based interventions (MBIs) have a positive effect on biomarkers of inflammation and stress in patients with psychiatric disorders and physical illnesses. Regarding subclinical populations, results are less clear. The present meta-analysis addressed the effects of MBIs on biomarkers in psychiatric populations and among healthy, stressed, and at-risk populations.

Differential associations of the two higher-order factors of mindfulness with trait empathy and the mediating role of emotional awareness.

Empathy enables us to understand the emotions of others and is an important determinant of prosocial behavior. Investigating the relationship between mindfulness and empathy could therefore provide important insights into factors that promote interpersonal understanding and pathways that contribute to prosocial behavior. As prior studies have yielded only inconsistent results, this study extended previous findings and investigated for the first time the associations of two important factors of mindfulness (Self-regulated Attention [SRA] and Orientation to Experience [OTE]) with two commonly proposed components of empathy (cognitive empathy and affective empathy).

The Psychological Science Accelerator's COVID-19 rapid-response dataset.

In response to the COVID-19 pandemic, the Psychological Science Accelerator coordinated three large-scale psychological studies to examine the effects of loss-gain framing, cognitive reappraisals, and autonomy framing manipulations on behavioral intentions and affective measures. The data collected (April to October 2020) included specific measures for each experimental study, a general questionnaire examining health prevention behaviors and COVID-19 experience, geographical and cultural context characterization, and demographic information for each participant. Each participant started the study with the same general questions and then was randomized to complete either one longer experiment or two shorter experiments.

Lexical access speed and the development of phonological recoding during immediate serial recall.

A recent Registered Replication Report (RRR) of the development of verbal rehearsal during serial recall (Elliott et al., 2021) revealed that children verbalized at younger ages than previously thought (Flavell et al., 1966), but did not identify sources of individual differences.

Effects of caste, birth season, and family income on digit ratios.

Objectives: The contributions of latitude and ethnicity in the determination of cross-society differences in digit ratios are unclear. In India, different castes (endogamous groups) have been living in the same areas (villages or towns) for the last 1500 years and, therefore, these groups may have different gene pools without a latitude-related difference component. Thus, in the present study, we studied the effect of caste on digit ratios.

Contextual factors predicting compliance behavior during the COVID-19 pandemic: A machine learning analysis on survey data from 16 countries.

Voluntary isolation is one of the most effective methods for individuals to help prevent the transmission of diseases such as COVID-19. Understanding why people leave their homes when advised not to do so and identifying what contextual factors predict this non-compliant behavior is essential for policymakers and public health officials. To provide insight on these factors, we collected data from 42,169 individuals across 16 countries.

In COVID-19 Health Messaging, Loss Framing Increases Anxiety with Little-to-No Concomitant Benefits: Experimental Evidence from 84 Countries.

The COVID-19 pandemic (and its aftermath) highlights a critical need to communicate health information effectively to the global public. Given that subtle differences in information framing can have meaningful effects on behavior, behavioral science research highlights a pressing question: Is it more effective to frame COVID-19 health messages in terms of potential losses (e.g.

No Effects of a Brief Mindfulness Intervention on Controlled Motivation and Amotivation, but Effect Moderation Through Trait Mindfulness: a Randomized Controlled Trial.

Objectives: Mindfulness is associated with the different forms of motivation according to self-determination theory (intrinsic, identified, and external motivation, and amotivation). However, causal evidence for reported negative associations of mindfulness with external motivation and amotivation is currently lacking. Therefore, this study investigated causal effects of a brief mindfulness intervention on motivation towards a personal goal.

The relationships of family income and caste-status with religiousness: Mediation role of intolerance of uncertainty.

The relationship between lower socioeconomic status (SES) and religiousness is well known; however, its (psychological mediation) mechanism is not clear. In the present study, we studied the mediation role of intolerance of uncertainty (IU; a personality measure of self-uncertainty) in the effect of SES on religiousness and its dimensions (i.e.

Dimensionality analysis of the German version of the Screen for Cognitive Impairment in Psychiatry (SCIP-G).

Background: Psychiatric disorders, especially schizophrenia, are characterised by cognitive impairment. The rapid detection of cognitive dysfunction - also in the course of the disease - is of great importance. The Screen for Cognitive Impairment in Psychiatry (SCIP) was developed to provide screening of psychiatric patients in clinical practice and is available in several languages.
