Understanding the Magnitude of Psychological Differences Between Women and Men Requires Seeing the Forest and the Trees

Unpacking interplays between competitiveness, cooperativeness, and social comparison orientation: A network psychometric approach and replication

Emerging evidence highlights the role of social comparison in competition and cooperation, yet the dynamics among competitiveness, cooperativeness, and social comparison orientation (SCO) remain underexplored. In the present study, we sought to unravel these complex interplays employing graphical Gaussian models (GGMs) and characterize the network structures utilizing cross-sectional data derived from 1073 Chinese participants. A pre-registered independent sample (n = 1348) served to examine the replicability and robustness of our initial findings. Moreover, we explored the Bayesian networks (i.e., directed acyclic graphs) to delve into their probabilistic directed dependencies. Our analysis identified an interpersonal co-opetition network where SCO bridges competitiveness and cooperativeness, emphasizing the key influence of the desire to surpass others. We also found a significant gender effect on the levels of these orientations but not on the network patterns. Additionally, the replication sample offered validation for the resultant network structure and its key nodes. In sum, these findings provide a new insight into the symbiotic relationship between competitiveness and cooperativeness within the framework of social comparison, offering significant theoretical and practical implications.

Psychometric Characteristics of the Italian Version of the Revised Sociosexual Orientation Inventory

Sociosexuality refers to the tendency to engage in uncommitted sexual behavior and has been dissected into three domains: sociosexual behavior, attitudes, and desire (Penke & Asendorpf, 2008), which led to the revised Sociosexual Orientation Inventory (SOI-R), which was validated on a German sample. The current research aimed at translating and validating an Italian version (I-SOI-R), administered to three distinct Italian participant groups. In the first sample (N = 710, females = 521, age = 18-59 years), we found evidence for a bifactor model, articulated in a general sociosexuality factor and three specific factors (behavior, attitudes, desire). High internal consistency was established for total and subscale scores, alongside favorable test-retest reliability. A connection was found between relationship status and sociosexual desire, though not gender dependent. We found evidence for test-retest reliability in a second sample (N = 55, females = 37, age 20-58 years). In a third study (N = 305, females = 147, age = 19-60 years), the earlier findings were replicated, further confirming the I-SOI-R's construct, criterion, and nomological validity on an online sample. Combining data from the three studies revealed full configural, metric, and scalar invariance regarding gender. This allowed us to meaningfully compare the observed scores of women and men and replicated the finding that men display higher levels of unrestricted sociosexuality. In conclusion, the I-SOI-R may serve as a valuable tool to assess and enhance sexual health, albeit warranting future research on construct and criterion validity.

Psychometric Evidence That Paraphilia Is a Natural Kind

Is the category paraphilia a natural kind? That is, do different paraphilias share anything scientifically interesting or are they classified together because they are unusual and sometimes problematic? We investigated this question systematically in 11 samples of paraphilic males (N = 4,617) and 11 samples of control males (N = 1,494). Primary data consisted of responses to the 11-item Paraphilic Interests Scale. Contrary to our initial hypothesis, the scale mean was similar for paraphilic and control samples. Using logistic regression and the same items, we derived three highly correlated measures that robustly discriminated paraphilic and control samples (ds ranging from 0.86 to 0.92). These successful measures capitalized on the unanticipated fact that some items (especially those assessing transvestism and masochistic humiliation) were positively associated with membership in paraphilic samples, while others (especially those assessing voyeurism) were negatively associated with such membership. Subsequent analyses focused on one of the measures, the Paraphilic Interests Scale Contrast (PISC). Consistent with prior findings distinguishing paraphilias and homosexual orientation, PISC was not elevated among homosexual males compared with heterosexual males among the control groups. Within four paraphilic samples, PISC was positively associated with additional paraphilic phenomena. Results provide tentative support for both the proposition that paraphilia is a natural kind and the usefulness of PISC as a measure of paraphilia.

Testosterone, gender identity and gender-stereotyped personality attributes

Sex/gender differences in personality associated with gender stereotyped behavior are widely studied in psychology yet remain a subject of ongoing debate. Exposure to testosterone during developmental periods is considered to be a primary mediator of many sex/gender differences in behavior. Extensions of this research has led to both lay beliefs and initial research about individual differences in basal testosterone in adulthood relating to "masculine" personality. In this study, we explored the relationships between testosterone, gender identity, and gender stereotyped personality attributes in a sample of over 400 university students (65 % female assigned at birth). Participants provided ratings of their self-perceived masculinity and femininity, resulting in a continuous measure of gender identity, and a set of agentic and communal personality attributes. A saliva sample was also provided for assay of basal testosterone. Results showed no compelling evidence that basal testosterone correlates with gender-stereotyped personality attributes or explains the relationship between sex/gender identity and these attributes, across, within, or covarying out sex assigned at birth. Contributing to a more gender diverse approach to assessing sex/gender relationships with personality and testosterone, our continuous measure of self-perceived masculinity and femininity predicted additional variance in personality beyond binary sex and showed some preliminary but weak relationships with testosterone. Results from this study cast doubt on the activational testosterone-masculinity hypothesis for explaining sex differences in gender stereotyped traits and within-sex/gender variation in attributes associated with agency and communality.

Experiences of sexist discrimination as a potential explanatory factor for alcohol and drug misuse among Latina young adult women

RATIONALE

Marianismo beliefs, or traditional female gender role beliefs among Latinas, have been found to serve as risk or protective factors linked with health risk behaviors in prior studies, including alcohol and drug misuse. However, limited research has examined potential factors that may contribute to or explain these associations. Sexist discrimination, which can serve as a significant stressor that may contribute to substance misuse, is one potential factor that may link marianismo beliefs and substance misuse among Latina young adult women.

OBJECTIVE

This study examined sexism as a potential mediator of hypothesized negative associations between five marianismo beliefs (Family Pillar, Virtuous and Chaste, Subordinate to Others, Silencing Self to Maintain Harmony, and Spiritual Pillar) and alcohol and drug misuse using structural equation modeling.

METHOD

Participants included 611 cisgender Latina full-time college student young adult women in the U.S. ages 18-26 who participated in an online cross-sectional survey about their health and behaviors.

RESULTS

Results delineated experiences of sexism as a significant risk factor for alcohol and drug misuse and as a potential explanatory factor that may partly explain associations between certain marianismo beliefs (i.e., Virtuous and Chaste beliefs) and substance misuse. Specifically, experiences of sexism partially accounted for the negative association between endorsement of the Virtuous and Chaste belief and increased alcohol and drug misuse among Latina young adults.

CONCLUSIONS

Prevention and intervention efforts should take a culturally responsive, gender-informed approach to address substance misuse among Latina young adults and address the negative influence of sexism on health.

"When" Versus "Whether" Gender/Sex Differences: Insights From Psychological Research on Negotiation, Risk-Taking, and Leadership

We present a conceptual framework of situational moderators of gender/sex effects in negotiation, risk-taking, and leadership-three masculine-stereotypic domains associated with gender/sex gaps in pay and authority. We propose that greater situational ambiguity and higher relevance and salience of gender/sex increase the likelihood of gender/sex-linked behaviors in these domains. We argue that greater ambiguity increases the extent to which actors and audiences must search inwardly (e.g., mental schema, past experience) or outwardly (e.g., social norms) for cues on how to behave or evaluate a situation and thereby widens the door for gender/sex-linked influences. Correspondingly, we propose that gender/sex effects on behavior and evaluations in these domains will be more likely when gender/sex is more relevant and salient to the setting or task. We propose further that these two situational moderators may work jointly or interactively to influence the likelihood of gender/sex effects in negotiation, risk-taking, and leadership. We conclude by discussing applications of our conceptual framework to psychological science and its translation to practice, including directions for future research.

A Systematic Review and New Analyses of the Gender-Equality Paradox

Some studies show that living conditions, such as economy, gender equality, and education, are associated with the magnitude of psychological sex differences. We systematically and quantitatively reviewed 54 articles and conducted new analyses on 27 meta-analyses and large-scale studies to investigate the association between living conditions and psychological sex differences. We found that sex differences in personality, verbal abilities, episodic memory, and negative emotions are more pronounced in countries with higher living conditions. In contrast, sex differences in sexual behavior, partner preferences, and math are smaller in countries with higher living conditions. We also observed that economic indicators of living conditions, such as gross domestic product, are most sensitive in predicting the magnitude of sex differences. Taken together, results indicate that more sex differences are larger, rather than smaller, in countries with higher living conditions. It should therefore be expected that the magnitude of most psychological sex differences will remain unchanged or become more pronounced with improvements in living conditions, such as economy, gender equality, and education.

Univariate and multivariate sex differences and similarities in gray matter volume within essential language-processing areas

BACKGROUND

Sex differences in language-related abilities have been reported. It is generally assumed that these differences stem from a different organization of language in the brains of females and males. However, research in this area has been relatively scarce, methodologically heterogeneous and has yielded conflicting results.

METHODS

Univariate and multivariate sex differences and similarities in gray matter volume (GMVOL) within 18 essential language-processing brain areas were assessed in a sex-balanced sample (N = 588) of right-handed young adults. Univariate analyses involved location, spread, and shape comparisons of the females' and males' distributions and were conducted with several robust statistical methods able to quantify the size of sex differences and similarities in a complementary way. Multivariate sex differences and similarities were estimated by the same methods in the continuous scores provided by two distinct multivariate procedures (logistic regression and a multivariate analog of the Wilcoxon-Mann-Whitney test). Additional analyses were addressed to compare the outcomes of these two multivariate analytical strategies and described their structure (that is, the relative contribution of each brain area to the multivariate effects).

RESULTS

When not adjusted for total intracranial volume (TIV) variation, "large" univariate sex differences (males > females) were found in all 18 brain areas considered. In contrast, "small" differences (females > males) in just two of these brain areas were found when controlling for TIV. The two multivariate methods tested provided very similar results. Multivariate sex differences surpassed univariate differences, yielding "large" differences indicative of larger volumes in males when calculated from raw GMVOL estimates. Conversely, when calculated from TIV-adjusted GMVOL, multivariate differences were "medium" and indicative of larger volumes in females. Despite their distinct size and direction, multivariate sex differences in raw and TIV-adjusted GMVOL shared a similar structure and allowed us to identify the components of the SENT_CORE network which more likely contribute to the observed effects.

CONCLUSIONS

Our results confirm and extend previous findings about univariate sex differences in language-processing areas, offering unprecedented evidence at the multivariate level. We also observed that the size and direction of these differences vary quite substantially depending on whether they are estimated from raw or TIV-adjusted GMVOL measurements.

Psychosocial interventions for suicidal and self-injurious-related behaviors among adolescents: a systematic review and meta-analysis of Chinese practices

Background

Suicidal and self-injurious-related behaviors (SSIRBs) are a serious public health challenge in China. However, a comprehensive systematic review of psychosocial interventions for SSIRBs among Chinese adolescents has not been performed. To fill this gap, this systematic review and meta-analysis aimed to examine psychosocial interventions for SSIRBs among Chinese adolescents.

Methods

Eight international (PubMed, EMBASE, Cochrane Library, ScienceDirect, Clinical Trial, CINAHL, PsycINFO, and Web of Science) and four Chinese (Wanfang, SinoMed, CEPS, and CNKI) databases were searched from inception to 31 January 2023. Data extraction and quality assessment were independently conducted by two groups of researchers. Qualitative synthesis and meta-analysis were both used.

Results

The initial search yielded 16,872 titles. Of the 649 full texts reviewed, 19 intervention articles focusing on SSIRBs met the inclusion criteria. Thirteen out of the 19 included studies involved cognitive-behavioral therapy (CBT). Seven non-suicidal self-injury (NSSI) studies assessing self-injurious behaviors were included (six short-term studies and three long-term studies). Compared with long-term interventions [-1.30 (95% CI: -1.84, -0.76)], short-term psychosocial interventions had a higher standardized mean difference (SMD) value [1.86 (95% CI: -2.72, -0.99)]. Meta-regression showed an inverse relationship between the treatment response and sample size (slope = 0.068, Z = 2.914, p = 0.004) and proportion of females (slope = 1.096, Z = 5.848, p < 0.001). Subgroup analyses showed that compared with the "less than 1 month" group [-0.494 (-0.783, -0.205)], in the "immediate postintervention" group, the pooled estimate was significantly lower [-2.800 (-4.050, -1.550), p < 0.001].

Conclusion

Our review systematically summarized the key characteristics and effectiveness of existing psychosocial interventions for SSIRBs among Chinese adolescents. Short-term psychosocial interventions for NSSI were significantly effective in reducing self-injurious behavior scores, especially in the immediate postintervention period. More favorable treatment responses could be observed in both male and small samples.

Do Measures of Systemizing and Empathizing Reflect Perceptions of Gender Differences in Learning Affordances?

Gender differences in systemizing and empathizing are sometimes attributed to inherent biological factors. We tested whether such effects are more often interpreted as reflecting men's and women's different learning affordances. Study 1 (N = 624) estimated gender differences in item-level activities from systemizing and empathizing scales (SQ, EQ) in large representative samples. Lay coders (Study 2, N = 199) and psychology experts (Study 3, N = 116) rated SQ and EQ activities as being more learned (vs. innate) and believed that men receive more systemizing and women receive more empathizing (Study 3 only) affordances. Items showing the largest gender differences in Study 1 were those rated as having the largest gender affordances (more than gendered genetic advantages) in Studies 2 and 3. Claims about inherent sex differences in systemizing, and to a lesser degree empathizing, appear to be out of step with a consensus view from the public and psychological scientists.

Sex Moderates the Relationship Between Social Support and Cardiovascular Prevention Behaviors in Middle-aged and Older Adults

BACKGROUND

Most risk factors for cardiovascular disease (CVD) are modifiable, suggesting that the burden of CVD could be substantially reduced through cardiovascular screening and healthier lifestyle. People who have social support are more likely to adhere to cardiovascular prevention recommendations, but it is not clear whether the benefit of social support is equal for men and women.

PURPOSE

We investigated whether sex moderates the relationship between social support and adherence to cardiovascular prevention recommendations in a nationally representative sample.

METHODS

Participants were 17,287 adults (n = 10,264 middle-aged adults 40-64 years old and n = 7,023 older adults ≥ 65 years old) who participated in the National Health Survey of Spain in 2017. Social support was measured with the Functional Social Support Questionnaire of Duke-UNC. Adherence to cardiovascular screening recommendations was assessed based on self-reported testing of cholesterol, blood pressure, and blood sugar by a health professional in the past 12 months. Adherence to recommended health-related behaviors was assessed based on the guidelines of the European Society of Cardiology regarding diet, alcohol consumption, smoking, and physical activity.

RESULTS

Multiple regression models adjusted for socio-demographic and cardiovascular history and risk variables showed that social support was more strongly associated with adherence to cardiovascular prevention recommendations in men than in women. In particular, low social support levels were especially detrimental for both middle-aged men (screening: B = 0.13, 95% CI [0.06-0.20], p < .001; behaviors: B = 0.33 [0.26-0.41], p < .001) and older men (screening: B = 0.10 [0.04-0.17], p = .001; behaviors: B = 0.16 [0.08-0.25], p < .001), whereas older women had comparatively high adherence, which was unrelated to social support (screening: B = 0.02 [-0.03 to 0.08], p = .433; behaviors: B = 0.03 [-0.03 to 0.10], p = .342).

CONCLUSIONS

Social support is more strongly associated with cardiovascular prevention in men than in women, such that men who lack social support have the lowest adherence to cardiovascular screening and lifestyle recommendations.

Gender equity in hiring: examining the effectiveness of a personality-based algorithm

Introduction

Gender biases in hiring decisions remain an issue in the workplace. Also, current gender balancing techniques are scientifically poorly supported and lead to undesirable results, sometimes even contributing to activating stereotypes. While hiring algorithms could bring a solution, they are still often regarded as tools amplifying human prejudices. In this sense, talent specialists tend to prefer recommendations from experts, while candidates question the fairness of such tools, in particular, due to a lack of information and control over the standardized assessment. However, there is evidence that building algorithms based on data that is gender-blind, like personality - which has been shown to be mostly similar between genders, and is also predictive of performance, could help in reducing gender biases in hiring. The goal of this study was, therefore, to test the adverse impact of a personality-based algorithm across a large array of occupations.

Method

The study analyzed 208 predictive models designed for 18 employers. These models were tested on a global sample of 273,293 potential candidates for each respective role.

Results

Mean weighted impact ratios of 0.91 (Female-Male) and 0.90 (Male-Female) were observed. We found similar results when analyzing impact ratios for 21 different job categories.

Discussion

Our results suggest that personality-based algorithms could help organizations screen candidates in the early stages of the selection process while mitigating the risks of gender discrimination.

Relative density clouds: Visualizing and exploring multivariate patterns of group differences

This paper introduces relative density clouds, a simple but powerful method to visualize the relative density of two groups in multivariate space. Relative density clouds employ k-nearest neighbor density estimates to provide information about group differences throughout the entire distribution of the variables. The method can also be used to decompose overall group differences into the specific contributions of differences in location, scale, and covariation. Existing relative distribution methods offer a flexible toolkit for the analysis of univariate differences; relative density clouds bring some of the same advantages to fruition in the context of multivariate research. They can assist in the exploration of complex patterns of group differences, and help break them down into simpler, more interpretable effects. An easy-to-use R function is provided to make this visualization method widely accessible to researchers.

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. In this study we calculated 63 d statistics of which 5 were d > 0.50 and 28 were d > 0.20. In two samples, each using two different instruments, men scored higher than women on Anti-Social, Narcissistic and Sadistic PD which is a consistent finding in the literature. Speculations are made about the origin of these differences. Limitations are acknowledged.

Beyond Simple Mean Differences: Analysis of Sex Similarities and Differences in Academic Achievement With the Kaufman Tests of Educational Achievement, Third Edition

Simple mean differences summarized in meta-analyses do not always adequately describe sex similarities and differences. We investigated sex similarities and differences in academic achievement test scores during childhood and adolescence multiple ways based on composite and subtest scores from the Kaufman Test of Educational Achievement (Third edition) norming sample. Sex differences in means were investigated across achievement domains and ability levels. Test score variance and percentages of scores at different parts of score distributions were also compared across sex. The largest and most consistent sex differences were female advantages in writing tests: Larger advantages were found in more complex writing tasks. Females also showed consistent advantages in silent reading fluency. Males demonstrated advantages in math problem solving that emerged at the average ability level. Females were more likely to be high achievers in reading fluency and written expression, whereas males were more likely to be low achievers in reading fluency and aspects of writing, and very low achievers in word recognition, word recognition fluency, and reading vocabulary. Males were more likely to be high achievers in math problem solving. Analysis that goes beyond simple mean differences reveals important sex differences regarding academic achievement, and theories should account for overall patterns of academic achievement similarities and differences.
