The Perceived Economic Scarcity Scale: A valid tool with greater predictive utility than income.

This article introduces the Perceived Economic Scarcity Scale (PESS), a novel instrument measuring the subjective evaluation and experience of economic scarcity (the feeling of having insufficient financial resources to meet one's needs). We conducted three high-powered preregistered studies (total N = 1900) to rigorously evaluate the PESS's psychometric properties. In Study 1, we generated a pool of items and used both Principal Component Analysis and Exploratory Factor Analysis to select the most appropriate items. In Study 2, we examined the PESS's construct validity, demonstrating that it measures a distinct construct from related constructs such as subjective social class. In Study 3, we examined the PESS's predictive validity, demonstrating that it is a robust predictor of both affective outcomes (e.g. anxiety-depressive symptoms) and cognitive outcomes (e.g. economic risk-taking). Critically, we found that the PESS not only has incremental validity over and above income but also has greater predictive utility than income. We also found that the PESS score varies depending on the distance-to-pay and has excellent test-retest reliability. Overall, the PESS appears to be a valid and reliable instrument for assessing perceived economic scarcity, and we encourage researchers to use it to better understand the psychological consequences of 'not having enough'.

Income Is a Stronger Predictor of Subjective Social Class in More Economically Unequal Places.

In this research, we examine how the lay conceptualization of subjective social class varies based on economic contexts. We argue that income should be a more central component of subjective social class in areas with higher income inequality. To address the issue of low power in existing research, we combined local-level income inequality indicators with large-scale repeated cross-sectional data, enabling the most reliable test to date on how the relationship between income and subjective social class is moderated by inequality. We used nationally representative datasets from the United States and South Korea (encompassing 25,000+ participants from 1,246 regional-year units). In both cultural contexts, our multilevel models revealed that income is a stronger predictor of subjective social class in regions with higher levels of income inequality. This work advances the theoretical and empirical understanding of how income and income inequality interact to shape the perception of one's position in the social hierarchy.

Exposure to the 1959-1961 Chinese famine and risk of non-communicable diseases in later life: A life course perspective.

Child undernutrition and later-life non-communicable diseases (NCDs) are major global health issues. Literature suggests that undernutrition/famine exposure in childhood has immediate and long-term adverse health consequences. However, many studies have theoretical and methodological limitations. To add to the literature and overcome some of these limitations, we adopted a life course perspective and used more robust methods. We investigated the association between exposure to the 1959-1961 Chinese famine and later-life NCDs and if this association depends on: life stage at exposure, famine severity, and sex. We conducted a secondary data analysis of a large-scale, nationally representative, longitudinal study-the China Health and Retirement Longitudinal Study (2011-2018, 11,094 participants). We measured famine exposure/severity using self-reported experience, life stage using age at exposure, and health using the number of NCDs. We performed Poisson growth curve models. We obtained three findings. First, compared with unexposed participants, those exposed before age 18 had a higher risk of later-life NCDs, particularly if exposed in-utero (IRR = 1.90, 95% CI [1.70, 2.12], p < .001) and in the "first 1,000 days" of life (IRR = 1.86, 95% CI [1.73, 2.00], p < .001; for 0-6 months group, IRR = 1.95, 95% CI [1.67, 2.29], p < .001). Second, the famine effects among participants moderately and severely exposed were similar (IRR = 1.18, 95% CI [1.09, 1.28], p < .001 and IRR = 1.24, 95% CI [1.17, 1.32], p < .001). Third, the famine effects did not differ between females and males (IRR = 0.98, 95% CI [0.90, 1.07], p = .703). In an individual's life course, in-utero and the "first 1,000 days" are a particularly sensitive time period with marked long-term implications for NCDs if undernutrition/famine is experienced in this period. However, this window remains open until young adulthood. This highlights the need to invest more in preventing and treating child/adolescent undernutrition to tackle later-life NCDs.

A Competitiveness-Based Theoretical Framework on the Psychology of Income Inequality.

Social scientists have begun to extensively study how living in contexts with high income inequality affects psychological outcomes. Herein we overview a conceptual framework that integrates, organizes, and extends these complex (and sometimes contradictory) findings. First, we describe studies showing that income inequality breeds an ethos of competitiveness. Second, we argue that the inequality-competitiveness relation explains why income inequality (a) promotes status-focused behaviors aimed at lifting oneself up and/or bringing others down, (b) harms social relations when they pose an obstacle to one's economic advancement, (c) exerts opposing effects on well-being via avoidance motivation (focusing on the risk of economic failure) and approach motivation (focusing on the prospect of economic success), and (d) represents a threat to those who perceive they do not have sufficient individual/contextual resources to cope with the demands of competition but a challenge to those with sufficient resources. We also discuss limitations and future directions for research.

Evolution of the income-related gap in health with old age: evidence from 20 countries in European and Chinese panel datasets.

Some studies show that the protective effect of higher income on health weakens with old age (age-as-leveller pattern), whereas others show that it strengthens with old age (cumulative advantage/disadvantage pattern). Many existing studies are limited in that they use single-country and/or single-timepoint designs. To overcome these limitations and better understand how the income-health gradient evolves in older age, we used cross-national and longitudinal data of the Survey of Health, Ageing and Retirement in Europe (2004-2019, N = 73,407) and the China Health and Retirement Longitudinal Study (2011-2018, N = 10,067). We operationalised health using multimorbidity and three alternative indicators (functional disability, mobility disability, and memory). We performed Poisson growth curve modelling to capture the between-participant effects of age and the within-participant effects of aging. We obtained three consistent and robust findings for Europe (patterns were observed in most countries) and China. First, the protective effect of higher income on multimorbidity, functional disability, and mobility disability was weaker for older than for younger adults (between-participant age-as-leveller pattern). Second, only the protective effect of higher income on mobility disability weakened over the later life course (within-participant age-as-leveller pattern). Third, the protective effect of higher income on memory was stronger for older than for younger adults and strengthened over the later life course (between-participant and within-participant cumulative advantage/disadvantage pattern). Longitudinal data, growth curve modelling distinguishing the between-participant from within-participant effect, and adjustments for potential confounders based on the hypothesised causal structure enabled us to better navigate the landscape of causal inference. Findings suggest that the income-related gap in physical health but not in cognitive health narrows in old age for both Europe and China.

Porn use and men's and women's sexual performance: evidence from a large longitudinal sample.

BACKGROUND: We examined whether young men and women differ in the relation between porn use and sexual performance (sexual self-competence, sexual functioning, and partner-reported sexual satisfaction). METHODS: We conducted a three-wave longitudinal study (spanning 2015-16-17) that involved a very large number of men and women in their early 20s (100 000 + French-speaking individuals; 4000 + heterosexual couples). RESULTS: The results revealed a twofold phenomenon. Among men, a higher frequency of porn use (wave 1) and increased porn use over time (waves 1-3) were associated with lower levels of sexual self-competence, impaired sexual functioning, and decreased partner-reported sexual satisfaction. In contrast, among women, higher and increasing frequencies of porn use were associated with higher levels of sexual self-competence, improved sexual functioning, and enhanced partner-reported sexual satisfaction (for some aspects). CONCLUSIONS: The findings reveal the irony that porn - a male-dominated industry that targets a male-dominated audience - is associated with the erosion of the quality of men's sex lives and the improvement of women's sex lives.

The effects of U.S. county and state income inequality on self-reported happiness and health are equivalent to zero.

PURPOSE: A popular idea in the social sciences is that contexts with high income inequality undermine people's well-being and health. However, existing studies documenting this phenomenon typically compare a small number of higher-level units (countries/regions). Here, we use local income inequality indicators and temporal designs to provide the most highly powered test to date of the associations between income inequality and self-reported happiness and health in the USA METHOD: We combined county-level income inequality data (county-level Gini coefficients) with the responses from the General Social Survey (GSS) Cross-sectional dataset (13,000 + participants from ≈1000 county-waves) and Panels (3 × 3000 + participants from 3 × ≈500 county-waves); we used the GSS happiness ("not too happy," "pretty happy," or "very happy") and health ("poor," "fair," "good," or "excellent") variables. RESULTS: Multilevel-ordered logistic models and equivalence tests revealed that the within-county effects of income inequality on self-reported happiness and health were systematically equivalent to zero. Additional analyses revealed that the within-state effects were identical, that using alternative measures of state income inequality led to the same conclusions, and that lagged effects (between + 1 and + 12 years) were never significant and always equivalent to zero. CONCLUSION: The present work suggests that-at least in the USA-income inequality is likely neither associated with self-reported happiness nor with self-reported health.

The paradox of local inequality: Meritocratic beliefs in unequal localities.

A puzzle has emerged amidst rising inequality: why do people profess high levels of belief in meritocracy even as income gains are increasingly concentrated at the top? In light of contradictory theories and evidence, we undertake the first assessment of the relationship between local income inequality and meritocratic beliefs outside the United States, using data from the UK Household Longitudinal Study. We find that the positive relationship between country-level income inequality and meritocratic beliefs identified in the recent literature does not translate straightforwardly below country level: there is no robust relationship between local income inequality and meritocratic beliefs in England. However, there is a robust-and somewhat paradoxical-positive association between high local income inequality and meritocratic beliefs among those with the lowest incomes. On average, respondents with annual household incomes of £10,000 are five points more likely (on a 100-point scale) to believe their hard work will pay off if they live in the most rather than the least unequal places in England. We also show that this applies beyond the specific case of meritocratic beliefs: low-income respondents in unequal places are also notably more satisfied with their own (low) income than similar respondents in more equal localities. In line with system justification theory, we argue that belief in meritocracy serves as an important tool of psychological resilience for low-income individuals who regularly come into contact with others more economically fortunate than themselves: though it legitimates their current position at the bottom of the status hierarchy, this belief also offers the promise of future advancement. While this reduces concern about the psychological effects of growing local income inequality on the most economically vulnerable, it also suggests that there is little prospect of demand for systemic economic change emerging from what might have been considered the most likely places.

The relationship of maternal rank, 5-HTTLPR genotype, and MAOA-LPR genotype to temperament in infant rhesus monkeys (Macaca mulatta).

Temperament is a construct whose manifestations are quantifiable from an early age, and whose origins have been proposed as "biological." Our goal was to determine whether maternal rank and infant genotype are associated with five measures of temperament in 3- to 4-month old rhesus monkeys (Macaca mulatta), all of whom were born and reared by their mothers in large, outdoor, half-acre cages. Maternal rank was defined as the proportion of animals outranked by each female, and the two genes of interest to us were monoamine oxidase and serotonin transporter, both of which are polymorphic in their promoter regions (MAOA-LPR and 5-HTTLPR, respectively), with one allele of each gene considered a "plasticity" allele, conferring increased sensitivity to environmental events. Our large sample size (n = 2014-3140) enabled us to examine the effects of individual genotypes rather than combining genotypes as is often done. Rank was positively associated with Confident temperament, but only for animals with the 5-repeat allele for MAOA-LPR. Rank had no other effect on temperament. In contrast, genotype had many different effects, with 5-HTTLPR associated with behavioral inhibition, and MAOA-LPR associated with ratings-based measures of temperament. We also examined the joint effect of the two genotypes and found some evidence for a dose-response: animals with the plasticity alleles for both genes were more likely to be behaviorally inhibited. Our results suggest phenotypic differences between animals possessing alleles for MAOA-LPR that show functional equivalence based on in vitro tests, and our data for 5-HTTLPR revealed differences between short/short homozygotes and long/short heterozygotes, strongly suggesting that combining genotypes for statistical analysis should be avoided if possible. Our analysis also provides evidence of sex differences in temperament, and, to our knowledge, the only evidence of differences in temperament based on specific pathogen-free status. We suggest several directions for future research.

Financial scarcity undermines health across the globe and the life course.

The gradient between income and health is well established: the lower the income, the poorer the health. However, low income (having few economic resources) may not be enough to characterize economic vulnerability, and financial scarcity (perceiving having insufficient economic resources) may further reduce health. First, analysis of cross-national data (275,000+ participants from 200+ country-years) revealed that financial scarcity was associated with twice the odds of suffering from reduced self-rated health and feelings of unhappiness; this association was observed in ≈90% of the country-years and explained variance over and above income. Second, analysis of national longitudinal data (20,000+ participants over 20 years of assessment) revealed that facing financial scarcity in the course of one's life decreased self-rated and objective health and increased feelings of depression; again, these effects explained variance over and above income. Two subsidiary findings were obtained: (i) three adverse life events (illness, separation, family conflicts) predicted financial scarcity over the life course, and (ii) self-mastery (a component of sense of control) accounted for the detrimental longitudinal effects of financial scarcity on health. This research suggests that to understand socioeconomic inequality in health, one should consider not only an individual's quantity of monetary resources but also the perceived sufficiency of these resources.

Income inequality, perceived competitiveness, and approach-avoidance motivation.

OBJECTIVE: Scholars disagree on whether income inequality has incentive or disincentive effects. In the present research, we move beyond such debate and focus on the motivational processes that income inequality predicts. First, income inequality makes economic stratification salient; therefore, it should promote perceived competitiveness. Second, competitiveness can be appraised as both a challenge and a threat; therefore, it should promote both approach and avoidance motivation. METHOD: In three studies (N = 2,543), U.S. residents from various ZIP codes reported the extent to which they perceived competitiveness in their town/city (Studies 1-3), as well as their economic achievement goals, achievement motives, and self-regulatory foci (Studies 2-3). RESULTS: Level of local income inequality was found to be a positive predictor-via increased perceived competitiveness-of other-approach economic goals, need for achievement, and promotion focus, as well as other-avoidance economic goals, fear of failure (specifically, the shame/embarrassment component), and prevention focus. Furthermore, actual and perceived income inequality were positively correlated. CONCLUSIONS: The conceptual and empirical work herein is the first to show how the economic environment predicts individuals' perceptions of competitiveness, influencing personal goals, motives, and orientations. It provides a more nuanced perspective on the implications of income inequality than perspectives currently available.

Income Inequality Affects the Psychological Health of Only the People Facing Scarcity.

Following the status-anxiety hypothesis, the psychological consequences of income inequality should be particularly severe for economically vulnerable individuals. Oddly, however, income inequality is often found to affect vulnerable low-income and advantaged high-income groups equally. We argue that economic vulnerability is better captured by a financial-scarcity measure and hypothesize that income inequality primarily impairs the psychological health of people facing scarcity. First, repeated cross-sectional international data (from the World Values Survey: 146,034 participants; 105 country waves) revealed that the within-country effect of national income inequality on feelings of unhappiness was limited to individuals facing scarcity (≈25% of the World Values Survey population). Second, longitudinal national data (Swiss Household Panel: 14,790 participants; 15,595 municipality years) revealed that the within-life-course effect of local income inequality on psychological health problems was also limited to these individuals (< 10% of the Swiss population). Income inequality by itself may not be a problem for psychological health but, rather, may be a catalyst for the consequences of financial scarcity.

Feeling Interpersonally Controlled While Pursuing Materialistic Goals: A Problematic Combination for Moral Behavior.

We created a life-goal assessment drawing from self-determination theory and achievement goal literature, examining its predictive power regarding immoral behavior and subjective well-being. Our source items assessed direction and energization of motivation, via the distinction between intrinsic and extrinsic aims and between intrinsic and extrinsic reasons for acting, respectively. Fused source items assessed four goal complexes representing a combination of direction and energization. Across three studies ( Ns = 109, 121, and 398), the extrinsic aim/extrinsic reason complex was consistently associated with immoral and/or unethical behavior beyond four source and three other goal complex variables. This was consistent with the triangle model of responsibility's claim that immoral behaviors may result when individuals disengage the self from moral prescriptions. The extrinsic/extrinsic complex also predicted lower subjective well-being, albeit less consistently. Our goal complex approach sheds light on how self-determination theory's goal contents and organismic integration mini-theories interact, particularly with respect to unethical behavior.

The student-institution fit at university: interactive effects of academic competition and social class on achievement goals.

As compared to continuing-generation students, first-generation students are struggling more at university. In the present article, we question the unconditional nature of such a phenomenon and argue that it depends on structural competition. Indeed, most academic departments use harsh selection procedure all throughout the curriculum, fostering between-student competition. In these departments, first-generation students tend to suffer from a lack of student-institution fit, that is, inconsistencies with the competitive institution's culture, practices, and identity. However, one might contend that in less competitive academic departments continuing-generation students might be the ones experiencing a lack of fit. Using a cross-sectional design, we investigated the consequences of such a context- and category-dependent lack of fit on the endorsement of scholastically adaptive goals. We surveyed N = 378 first- and continuing-generation students from either a more competitive or a less competitive department in their first or final year of bachelor's study. In the more competitive department, first-to-third year decrease of mastery goals (i.e., the desire to learn) was found to be steeper for first- than for continuing-generation students. In the less competitive department, the reversed pattern was found. Moreover, first-to-third year decrease of performance goals (i.e., the desire to outperform others) was found to be steeper within the less competitive department but did not depend on social class. This single-site preliminary research highlights the need to take the academic context into account when studying the social class graduation gap.

Performance goals in conflictual social interactions: towards the distinction between two modes of relational conflict regulation.

Socio-cognitive conflict has been defined as a situation of confrontation with a disagreeing other. Previous research suggests that individuals can regulate conflict in a relational way, namely by focusing on social comparison between relative levels of competences. Relational conflict regulation has been described as yielding particularly negative effects on social interactions and learning, but has been understudied. The present research addresses the question of the origin of relational conflict regulation by introducing a fundamental distinction between two types of regulation, one based on the affirmation of one's own point of view and the invalidation of the other's (i.e., 'competitive' regulation), the other corresponding to the protection of self-competence via compliance (i.e., 'protective' regulation). Three studies show that these modes of relational conflict regulation result from the endorsement of distinct performance goals, respectively, performance-approach goals (trying to outperform others) and performance-avoidance goals (avoiding performing more poorly than others). Theoretical implications for the literature on both conflict regulation and achievement goals are discussed.

Did my M.D. really go to University to learn? Detrimental effects of numerus clausus on self-efficacy, mastery goals and learning.

Exams with numerus clausus are very common in Medicine, Business Administration and Law. They are intended to select a predefined number of academic candidates on the basis of their rank rather than their absolute performance. Various scholars and politicians believe that numerus clausus policies are a vector of academic excellence. We argue, however, that they could have ironic epistemic effects. In comparison with selective policies based on criterion-based evaluations, selection via numerus clausus creates negative interdependence of competence (i.e., the success of some students comes at the expense of the others). Thus, we expect it to impair students' sense of self-efficacy and--by extension--the level of mastery goals they adopt, as well as their actual learning. Two field studies respectively reported that presence (versus absence) and awareness (versus ignorance) of numerus clausus policies at University was associated with a decreased endorsement of mastery goals; this effect was mediated by a reduction in self-efficacy beliefs. Moreover, an experimental study revealed that numerus clausus negatively predicted learning; this effect was, again, mediated by a reduction in self-efficacy beliefs. Practical implications for the selection procedures in higher education are discussed.
