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.

Personality and Interpersonal Influence: Low Adjustment and Low Competitiveness is Associated With Low Assertiveness.

This study examined the relationship between personality and interpersonal assertiveness styles, an important and neglected topic. In all, 396 working adults completed a six-factor personality test measuring work-related traits (HPTI) and a two-dimensional assessment of interpersonal styles (III) assessing four styles: Assertiveness, Passiveness, Hostile aggression, and Manipulative aggression. We were particularly interested in the correlates of aggressive and passive behaviour, as opposed to assertive behaviour.

Understanding how the presence of music in advertisements influences consumer behaviour.

This study investigated how consumer behaviour is influenced by music's emotional valence (sad vs. happy) in advertisements. Female participants (N = 134) watched the same four advertisements with either happy or sad background music.

Social, Demographic, and Psychological Factors Associated with Middle-Aged Mother's Vocabulary: Findings from the Millennium Cohort Study.

Based on a sample of 8271 mothers, this study explored a set of psychological and sociodemographic factors associated with their vocabulary, drawing on data from a large, nationally representative sample of children born in 2000. The dependent variable was maternal vocabulary assessed when cohort members were at fourteen years of age, and the mothers were in their mid-forties. Data were also collected when cohort members were at birth, 9 months old, and at ages 3, 7, 11 and 14 years.

Correlates of climate change skepticism.

While much research has examined the correlates of climate change beliefs from an alarmist perspective, less work has systematically measured climate change skepticism. This study aims to create a comprehensive tool capturing climate skeptics' beliefs and test its association with individual difference variables. 502 European adults completed a 22-item questionnaire on climate change (CC) skepticism as well as measures of ambiguity tolerance, belief in a just world (BJW), dark-side personality traits, and self-esteem.

Correlates of the Dark Tetrad.

This study explored demographic, ideological, self-rating and personality traits correlates of the Dark Tetrad (DT4) which measures Narcissism (Special), Machiavellianism (Crafty), Psychopathy (Wild), and Sadism (Mean) traits. In total, 447 adults completed three tests: a bright-side, work-related, personality test (HPTI: High Performance Type Indicator), a dark-side test (Short Dark Tetrad) and a number of self-ratings. Correlations and regressions showed that all four dark traits were associated with low Adjustment (Neuroticism), but also with high Risk-Taking and Competitiveness (low Agreeableness).

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.

"Never mind the fine print": The interaction of semantics with attitude strength beliefs on corporate cover-ups.

This study examined the interaction between attitude strength and the cognitive constraints imposed by the semantic properties of measurement items. It made use of digital algorithms and built on the semantic theory of survey response (STSR), examining how people who hold strong beliefs about contemporary issues violate cognitive constraints in expressing strong attitudes. We examined the beliefs people hold concerning attempts to hide, or cover up, information about organisational scandals.

Correlates of Conscientiousness: Findings from the Millennium Cohort Study.

This study explored correlates of the trait Conscientiousness drawing on longitudinal data from the Millennium Cohort Study (MCS), with a sample of 7,436 mothers. Data were collected when participants' children were born and again at ages nine months, 3, 11, and 14 years. Structural equation modeling showed that the family poverty indicator, self-esteem, parent-child relationship, children's behavioral problems, and education all had significant and direct effects on maternal trait Conscientiousness.

Sex and national differences in internet addiction in Egypt and Saudi Arabia.

Background: Understanding individual differences in psychology, and how they relate to specific addictions, may allow society to better identify those at most risk and even enact policies to ameliorate them. Internet addiction is a growing health concern, a research focus of which is to understand individual differences and the psychology of those most susceptible to developing it. Western countries are strongly overrepresented in this regard.

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.

Maladaptive (dark-side) and adaptive (bright-side) personality traits and defense styles.

This study explores the relationship between bright- and dark-side personality traits and four major styles of defense mechanisms (DMs) as this relationship remains unexplored and important in understanding the DMs. In all, 435 adult working participants (241 men; 194 women; Mean age 46.06 yrs) mainly in middle management jobs, completed a 78-item, six-trait measure of bright-side personality (HPTI: High Potential Type Indicator), a 25-item five-trait measure of the dark-side personality (PID-5;BF: DSM-5-Brief Form) and 88-item, four-styles measure of defense mechanisms (Defense Style Questionnaire).

The Big-Five personality factors, cognitive ability, health, and social-demographic indicators as independent predictors of self-efficacy: A longitudinal study.

This study set out to examine to what extent a set of psychological, health and socio-demographic factors are associated with self-efficacy (SE) in a large sample of over 12,000 participants over a two-year period. We were interested in the correlates of self-efficacy (criterion variable) with gender, age, education and occupation, the Big-Five personality factors and cognitive ability, as well as mental and physical health (predictor variables). Regression analyses showed that four of the Big-Five personality factors (extraversion, neuroticism, conscientiousness, and openness), cognitive ability, mental and physical health, gender, education and occupation were all significant and independent predictors of self-efficacy, accounting for 23% of the variance of the outcome variable.

Intelligence, Personality and Tolerance of Ambiguity.

In this study, 3836 adults completed a personality test (the HPTI) and a multidimensional intelligence test (GIA). Two prominent theories that link personality traits to intelligence (compensation and investment) were tested. There were more sex differences in the personality traits than in the IQ scores.

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.

Social Distancing and Shopping Behaviour: The Role of Anxiety, Attention, and Awareness on Safety Preferences while Queuing during the COVID-19 Pandemic.

The COVID-19 pandemic increased global anxiety, and many people shopped less frequently. This study quantifies customer preferences in where to shop while following social distancing regulations, specifically focusing on customers' anxiety. Collecting data online from 450 UK participants, we measured trait anxiety, COVID-19 anxiety, queue awareness, and queue safety preferences.

Sex in the dark: Sex differences on three measures of dark side personality.

This study examined sex differences in the scores on three different measures of the personality disorders (PDs) all derived from on-line surveys. Two groups (total N = 871) completed the Coolidge Axis-II Inventory which assessed 14 PDs; two groups (total N = 732) completed the Short Dark Tetrad which assessed 4 PDs; four groups (total N = 1558) completed the Personality Inventory for DSM-5-Brief Form which assessed 5 PD dimensions. Cohen's d after ANOVAs, and binary regression analysis revealed consistent findings.

Beliefs about personal change.

In all, 510 Europeans completed an online questionnaire rating their beliefs about personal change, including the established Dweck Mindset measure. Their ratings of 27 characteristics from BMI to sexual preference factored into 5 interpretable factors labelled Personality, Beliefs and Habits, Health, Social Status and Physical. Correlation indicated beliefs about change were most related to religious beliefs but also sex and age.

Are some interoceptive sensibility components more central than others? Using item pool visualisation to understand the psychometric representation of interoception.

Interoception refers to the processing of stimuli originating within the body and is widely considered a multidimensional construct. However, there remains a lack of consensus regarding the definition and measurement of the subjective, self-reported component, referred to here as interoceptive sensibility. As a contribution to knowledge on the topic, we sought to examine the construct commonality and distinguishability of seven self-report measures of interoceptive sensibility using Item Pool Visualisation (IPV), an illustrative method that locates item pools from within the same dataset and illustrates these in the form of nested radar charts.

Sex Difference in Estimated Intelligence and Estimated Emotional Intelligence and IQ Scores.

In five different online studies of community samples, participants ( > 2,200) estimated their IQ and EQ on a single scale and completed three different, short, untimed intelligence tests. In all studies, women estimated their IQ significantly lower than men (effect sizes from 0.22-0.

Money attitudes, financial capabilities, and impulsiveness as predictors of wealth accumulation.

In this study we examined three correlates of personal wealth-financial capability, buying impulsiveness, and attitudes to money in a large UK adult sample (N = 90,184). We were interested in how these psychological variables related to personal wealth controlling for well-established demographic correlates: age, education, gender, and household income. We drew on three personal wealth variables based on savings and investments, property wealth and personal items.

Sex Does Not Sell: The Effect of Sexual Content on Advertisement Effectiveness and Interference with Memory for Program Information.

Does increasing the sexual content of advertisements lead, though memory processes, to greater sales? By employing a between-participants design, we aimed to explore how sexual advertising affects explicit and implicit memory, and whether it impairs memory for information preceding the commercials (retroactive interference) or following the commercials (proactive interference). We randomly assigned 182 young participants in the UK to one of two groups who watched the same TV program containing an advertisement break during which either sexual or nonsexual advertisements were shown, while brands were held constant across conditions. Participants were then tested on their explicit and implicit memory for both the advertising content and program information.

Dispositional and ideological factor correlate of conspiracy thinking and beliefs.

This study explored how the Big Five personality traits, as well as measures of personality disorders, are related to two different measures of conspiracy theories (CTs)The two measures correlated r = .58 and were applied to examine generalisability of findings. We also measured participants (N = 397) general knowledge levels and ideology in the form of religious and political beliefs.

Correlates of belief in climate change: Demographics, ideology and belief systems.

This paper reports on two studies that examine correlates of attitudes to climate change (ACC). In the first study, five hundred participants completed five questionnaires and an intelligence test as well as two related measures of ACC. Using correlations and regressions we examined the relationship between ACC and demography (gender, age, education), ideology (political and religious beliefs), intelligence, self-beliefs, Belief in a Just World and the endorsement of Conspiracy Theories.
