Failure effects and gender differences in perfectionism

Perfectionism is a dimension which has been studied very little as a separate entity. It is not even considered as a nosological factor. No classification of the medical sciences underlines its importance other than to speak of a personality trait, of an aspect, or of a parameter. Nevertheless, perfectionism is related to multiple disorders such as depression (18, 20, 36), suicide (8, 16, 55), nutritional problems (11, 28), anxiety (3), obsessive-compulsive personality disorder (53), social phobia (2), as well as insomnia (46). Certain authors stress the possible role of perfectionism in the development or the persistence of a substantial number of these disorders (7, 22, 38). Given these facts, it is all the easier to understand the interest shown by clinicians and researchers in the subject. Better detection and evaluation of its impact on behaviour is important in putting therapies in place (6, 53). Relationships between perfectionism and fear of failure have been approached (21, 51, 54). Correlations between perfectionism and high levels of state and trait anxiety have been demonstrated (23). The evaluation of perfectionism has been dealt with very little. Some questionnaires devote a sub-category to it, such as the Eating Disorder Inventory and the Irrational Beliefs Test. However, recently, it has been recognized that perfectionism is a multidimensional construct. Two Multidimensional Perfectionism Scales have been developed and investigated in relative isolation. Frost, Marten, Lahart and Rosenblate defined perfectionism as the setting of excessively high standards for performance associated with critical self-evaluation. Six dimensions are described: concern over making mistakes, high personal standards, parental expectations, parental criticism, doubt about quality of performance and organization. Internal consistency and validity have been established (25, 26). Hewitt and Flett (30, 31, 33, 35) have developed another approach where three dimensions of perfectionism are described: SOP (Self Oriented Perfectionism) related to high standards and self criticism, SPP (Socially Prescribed Perfectionism) related to the need of approval from others and fear of negative evaluation, OOP (Other-Oriented Perfectionism) reflecting a tendency to set high expectations for others and to evaluate them in a demanding way; this component is related, especially for males, to self-esteem, hostility and authoritarianism. Validity and internal consistency have been established too (30, 31, 35). The Frost and al's Multidimensional Perfectionism Scale and the Hewitt and Flett's scales are closely associated, except concerning the OOP. Because this component could provide new information, we have chosen the second scale, referring to the French translation and validation of Labrecque (45). EMP is the French name of MPS; it is a self-report questionnaire of 45 questions, in fact three subscales of 15 items rated on a 7-point Likert-type scale. MPS was administered to 617 first year students at the university of Liège (table II). Differences are considered according to gender and experience of failure i.e. the fact of repeating an academic year. We realized a component analysis with promax rotation. Among the different possibilities offered by the scree-test the choice of a 4 factor solution stresses the original structure: SOP (14 items), SPP (12 items), OOP (9 items) and anti OOP (10 items); the last one is additional but allows for respecting semantics and saturation of the items. The first aim of confirming validity and internal consistency is satisfactory. In other respects the multidimensional structure of the concept leads to consideration of a positive, adaptive perfectionism and a more negative perfectionism, facilitating psychopathology (59, 60, 61). So it seems interesting to compare the different components of MPS in order to find an eventual sex-failure effect. The evaluation of perfectionism is obvious, considering it as a personality trait, but it can be used also in taking into account stress and its impact, for instance that of academic performance (29, 37, 39, 58). Conferring on MPS more pertinence in gender differentiation and failure evaluation is an other goal of this research. Through the particular choice of statistical results, sex and sex-failure effects can be demonstrated: a MANOVA underlines sex effect (lambda de Wilks = 0.96, p = 0.001) and sex-failure effect (lambda de Wilks = 0.98, p = 0.05). Structure of MPS is different in four groups (FE: women with failure, FnE: women without failure, ME: men with failure, MnE: men without failure). ANOVA show differences of MPS3, MPS1 and MPS2. Far more promising is the use of LISREL method allowing for the construction of a coherent model of relationships between some dimensions of MPS and Test-Anxiety, approached here with THEE (test d'habileté aux études et à leur évaluation) French abbreviated version (49) of TASTE (Test for Ability to Study and Evaluation). In fact according to the literature of fear of failure, girls score higher on anxiety and procrastination but less on self-confidence. The structural model shows different pathways, more especially between SPP (socially prescribed perfectionism), T2 (sense of incompetence) and T1 (anxiety). SOP (self oriented perfectionism) and SPP (socially prescribed perfectionism) by girls are very much correlated; it seems that they are more subjected to society and its exigencies of studying but consequently they are more at risk of anxiety and a sense of incompetence. SOP (self oriented perfectionism) by boys functions more indiscriminately of SPP (socially prescribed perfectionism) and is negatively correlated with self-incompetence; boys are more self-confident but they usually procrastinate more probably because failure expectancies would be particularly harmful for their self-esteem; consequently, failure should be related to something else than their own capacity; this may be an explanation of the high rate of male dropouts and failure in the first year at the university of Liège; also a factor explaining the female domination at the university. In the same way the first choice of studies is moving towards shorter and less difficult orientation (46). In case of failure the model is very similar according to gender: SOP (self oriented perfectionism) and T1 (anxiety) are directly connected; SOP and SPP are in this case better correlated by boys but the path between SPP, sense of incompetence and anxiety is less significant than in girls. In conclusion, providing some modifications according to semantics, the choice of a four factor solution allows for confirmation of the original structure of MPS and for internal consistency. The different components of MPS vary according to gender: SOP and more OOP discriminate men and women; SPP allows for differentiating women with failure. A structural model enhances the role of perfectionism in the cognitive and behavioural contexts; for instance it clarifies its action on fear of failure and success rates according to gender.     

Psychiatric co-morbidity and gender differences in intellectual disability

Background Although gender differences in psychopathology among the general psychiatric population appear to be well documented, such differences have been either ignored or inconsistently investigated among people with intellectual disability (ID). Methods The study examined psychiatric co‐ morbidity in 295 men and 295 women with ID and significant social impairments living in community settings. The sample was drawn from consecutive clinical referrals to a specialist mental heath service of South‐East London. Psychiatric diagnoses were based on ICD‐10 criteria. Results Personality disorder was more common among men, although dementia and adjustment reaction were more common among women. There were also gender differences in marital status, with a larger percentage of women being either married or in a stable relationship. Gender differences in the source of referral were also observed, with more women being referred through primary care and more men being referred through generic mental health services. Conclusions Female patients seem to have at some extent different mental health needs from male patients. Such differences should be taken into account in the design and delivery of clinical service for people with ID.     

Self-disclosure in psychotherapy supervisors: gender differences

OBJECTIVE: This article will explore the possible reasons for gender differences found in self-disclosure in psychotherapy supervisors. METHOD: Trainees and supervisors in the Brown University Department of Psychiatry and Human Behavior completed a questionnaire that asked about the appropriateness of the actions of a psychotherapy supervisor. RESULTS: On three items, male and female supervisors differed significantly in their perceptions of appropriate boundaries. These items were: interacting with the resident alone outside of supervision e.g. playing tennis (p = .0005), publishing identifiable content of supervision discussions with resident's consent (p = .0006), and disclosing the supervisor's prior struggles with substance abuse (p = .0008). Female supervisors answered "never" to these items in greater numbers than the male supervisors, who, for the most part answered "occasionally". CONCLUSION: Traditional gender role behaviors and differential gender socialization patterns are possible reasons for the gender difference in perception of boundaries by supervisors.     

Hemispheric and facial asymmetry: gender differences

Facial asymmetry (facedness) of female and male college students was investigated. Comparisons of facedness were made between 45 female and 45 male Dartmouth undergraduates. Facedness was defined in terms of the relative sizes (in square centimetres) of the two hemifaces. Data were derived from measurements of two-dimensional frontal photographs of the subjects. Reliable differences in facedness were found between the two groups. The females on average were found to be right faced, the males left faced. This difference was interpreted in terms of the contralateral control (below the eyes) of the two sides of the face by the two hemispheres, and the known differences in cognitive processing by the two hemispheres (left hemisphere-verbal; right hemisphere-visuospatial) in females and males. The observed difference in facial asymmetry between the two sexes is attributed to differential muscular development of the two sides of the face as related to the factors just noted. Suggestions are made for further research on facedness, particularly in relation to different age groups.

Adolescent adjustment in a nationally collected sample: identifying group differences by adoption status, adoption subtype, developmental stage and gender

The current study investigated group differences in adolescent adjustment by adoption status and adoption subtype in a national sample, in contrast to group differences based on developmental stage or gender. Secondary analyses of the National Longitudinal Study of Adolescent Health were performed to describe group differences in a broad range of adjustment measures (a) between adoptees and non-adoptees, (b) between different-race adoptees and same-race adoptees and, (c) across adolescent developmental stage and gender groups. Based upon a developmental deviance hypothesis, the current study hypothesized that early adolescent different-race adoptees would fair better across measures of academic performance, familial relationships, psychological adjustment, and physical health than their middle and late adolescent counterparts. Group comparisons revealed little evidence of increased maladjustment among adopted adolescents compared to non-adopted study participants. In addition, group comparisons revealed few differences across indices of adolescent adjustment by adoption subtype (i.e. by the degree of racial congruence adopted child and adoptive parent). However, significant group differences in adolescent adjustment were found based on participants' developmental stage and gender. The implications of the findings are discussed.     

Neuropsychological impairment and gender differences in HIV-1 infection

Aims: Research into neuropsychological consequences of HIV has focused mainly on male subjects, and therefore very little is known about the disease in female subjects and, of course, about gender differences. The aim of the present research was therefore to investigate neuropsychological impairment rates and pattern in HIV male and female patients, with regard to the study of gender differences in tasks assessing attention, memory for texts, digits and words, psychomotor speed, verbal intelligence and abstract reasoning. Methods: A clinical sample was recruited consisting of 122 subjects, divided into four groups: (i) 57 HIV+ men; (ii) 31 HIV+ women; (iii) 18 HIV? men and (iv) 16 HIV? women. All the subjects had more than 18 years, being the average of age of 34.08 for men and 33.35 for women. The evaluation of each subject consisted of a semistructured interview investigating sociodemographic, clinical and toxicological aspects and a neuropsychological assessment, with a battery of tests specifically selected for this study and chosen for their validity and because they have been shown to be sensitive to neuropsychological impairment in HIV‐infected patients in other studies. Results: None of HIV? male and female groups fulfilled impairment criteria. Regarding the HIV+ group, a rate of neuropsychological impairment of 51.9% was obtained for the men and 54.8% for the women, but there were no significant differences between groups. Nevertheless, were detected significant differences in neuropsychological impairment rates between HIV+ and HIV? women, and also between HIV+ and HIV? men. Although HIV+ women presented multiple factors that could increase their neuropsychological vulnerability to the effects of HIV, HIV+ men had the same probability of having neuropsychological impairment as HIV+ women. Conclusions: A different neuropsychological impairment pattern was detected between genders: while HIV+ men had greater impairment in visual memory, attention, psychomotor speed and abstract reasoning, HIV+ women had greater impairment on attention, psychomotor speed and verbal memory for texts.     

Sex differences in face gender recognition in humans

Human faces are ecologically-salient stimuli. Face sex is particularly relevant for human interactions and face gender recognition is an extremely efficient cognitive process that is acquired early during childhood. To measure the minimum information required for correct gender classification, we have used a pixelation filter and reduced frontal pictures (28,672 pixels) of male and female faces to 7168, 1792, 448 and 112 pixels. We then addressed the following questions: Is gender recognition of male and female faces equally efficient? Are male and female subjects equally efficient at recognising face gender? We found a striking difference in categorisation of male and female faces. Categorisation of female faces reduced to 1792 pixels is at chance level whereas categorisation of male faces is above chance even for 112 pixel images. In addition, the same difference in the efficiency of categorisation of male and female faces was detected using a Gaussian noise filter. A clear sex difference in the efficiency of face gender categorisation was detected as well. Female subject were more efficient in recognising female faces. These results indicate that recognition of male and female faces are different cognitive processes and that in general females are more efficient in this cognitive task.     

Adolescent leisure dimensions, psychosocial adjustment, and gender effects

Leisure provides the context for much of adolescent behaviour and development. While both theory and research point to the benefits of participation in leisure activities that are highly structured, the association between structured leisure and psychosocial adjustment is not uniformly high. This paper presents a model of adolescent leisure comprising three dimensions: structure, effort, and social contact. Adolescent adjustment is hypothesized to increase with participation in activities characterized by each of these attributes. Adjustment is also predicted to vary with gender, and with the interaction of gender and leisure participation. These propositions were tested in a questionnaire-based study of 433 Australian adolescents. Results revealed majority support for hypotheses pertaining to the positive effects of the leisure dimensions, and for gender differences in leisure participation and adjustment. Evidence was also obtained of gender-differentiated effects of leisure on adjustment, with social leisure predicting adjustment more strongly in females than males.     

Functional connectivity predicts gender: Evidence for gender differences in resting brain connectivity

Prevalence of certain forms of psychopathology, such as autism and depression, differs between genders and understanding gender differences of the neurotypical brain may provide insights into risk and protective factors. In recent research, resting state functional magnetic resonance imaging (rfMRI) is widely used to map the inherent functional networks of the brain. Although previous studies have reported gender differences in rfMRI, the robustness of gender differences is not well characterized. In this study, we use a large data set to test whether rfMRI functional connectivity (FC) can be used to predict gender and identify FC features that are most predictive of gender. We utilized rfMRI data from 820 healthy controls from the Human Connectome Project. By applying a predefined functional template and partial least squares regression modeling, we achieved a gender prediction accuracy of 87% when multi‐run rfMRI was used. Permutation tests confirmed that gender prediction was reliable ( ). Effects of motion, age, handedness, blood pressure, weight, and brain volume on gender prediction are discussed. Further, we found that FC features within the default mode (DMN), fronto‐parietal and sensorimotor networks contributed most to gender prediction. In the DMN, right fusiform gyrus and right ventromedial prefrontal cortex were important contributors. The above regions have been previously implicated in aspects of social functioning and this suggests potential gender differences in social cognition mediated by the DMN. Our findings demonstrate that gender can be reliably predicted using rfMRI data and highlight the importance of controlling for gender in brain imaging studies.     

Adolescent aggression: effects of gender and family and school environments

The present study examined the influence of family and classroom environments on the development of particular individual characteristics, including level of empathy, attitude to institutional authority and perceived social reputation, and the role these characteristics may in turn play in school aggression. Participants were 1319 adolescents aged 11-16 (47% male) drawn from state secondary schools in Valencia (Spain). Since previous studies suggest that these variables may contribute differentially to aggressive behaviour depending on adolescent gender, two different mediational structural models were calculated, respectively, for boys and girls. Results obtained confirmed the associations expected among the variables considered in the structural equations tested and pointed out different paths for boys and girls. Overall, our findings suggested that a positive family environment seems to be a stronger protective factor for girls in the development of problems of behaviour at school, whereas for boys this is the case for a positive classroom environment. This model accounted for 40% of the variance in aggression at school for boys and 35% for girls.     

Transnational stability of gender differences in schizophrenia?

Summary Gender-specific analyses of the multinational WHO-Determinants of Outcome-Study (including 1,292 cases from 10 countries) demonstrate the transnational stability of major findings on gender differences in schizophrenia: Male patients have an earlier mean age at onset in all countries. In female patients, the distribution of the age at onset shows a second peak after age 40 years. No gender differences on nuclear symptoms of schizophrenia can be detected, but on uncharacteristic symptoms, particularly some aspects of the illness behaviour, differences appear. This investigation supports the transcultural validity of gender differences found in the German ABC-Schizophrenia-Study and in the Danish-German Psychiatric Case Register studies.     

The role of estrogens in schizophrenia gender differences

The male/female differences that have been described in schizophrenia are important because they may ultimately shed light on factors that mediate the expression of schizophrenic illness. The hypothesis of this article is that estrogens, either directly or indirectly, modify symptom expression and account for many of the observed gender differences. The role of sex hormones is divided into organizational and activational effects. Organizational effects take place during a critical period in fetal life and put a permanent stamp on the developing brain. Activational effects are the direct influences of circulating hormones that appear when hormonal levels rise, and wane when hormonal levels drop. Because levels of sex hormones in adult women fluctuate during the menstrual cycle, cyclic effects of high and low female hormones may induce specific responses by the adult female brain. All these effects have implications for genetic, environmental, pharmacological, neurocognitive, clinical, and epidemiological research in schizophrenia.     

Dialectal and gender differences in nasalance for a Mandarin population

The purpose of this study was to determine whether there are dialectal and gender related differences in nasalance of main Mandarin vowels and three sentences in 400 Chinese normal adults. The mean nasalance score difference for dialect and gender was significant (p < .001) in all speech materials. For different dialects, the average nasalance scores show that Chongqing > Beijing > Shanghai > Guangzhou for the nasal sentence, oro-nasal sentence, /a/, /i/ and /u/. In addition, the average nasalance scores of females were higher than those of males for all speech materials in all dialects. The clinical significance of this study can be helpful in making nasalance clinical decisions for Chinese people with cleft palate, hearing disorders and dysarthria with resonance disorders. It also shows the theoretical and socio-cultural features for linguists considering dialects and gender.     

Developmental changes and gender differences in adolescents' perceptions of friendships

This five-wave study aims to investigate the development of adolescents' perceptions of support, negative interaction, and power in best friendships from ages 12 to 20 years. Furthermore, gender differences and linkages between the three dimensions are explored. A total of 593 early adolescents (53.6% boys) and 337 middle adolescents (43.3% boys) participated. A multigroup multivariate accelerated growth curve showed an increase of support for both boys and girls. Negative interaction was found to temporarily increase and then decrease for boys, while remaining stable for girls. Power temporarily increased for boys and decreased for girls. Results indicated that (1) friendships become more supportive during adolescence, (2) power issues are more prominent in friendships of boys and more powerful peers are perceived as more supportive by boys but not by girls, and (3) friendships of boys show a lagged development towards more equality.     

A study on gender and age differences in sleep spindles

In the present work, gender differences in sleep spindle topography were examined in 40 subjects. Their median age was 32 years (range 22-49 years). Spindles were detected from 3,306,060 s of visually scored stage 2 sleep EEG by a previously validated automatic fuzzy detector at 1-second intervals. A total of 271,168 spindles were found from the six EEG channels analyzed. Females showed a significantly higher percentage of spindles in the left frontal channel than males (Fp1-A2; p = 0.026). To confirm that this difference was gender and not age related, the subjects were divided into two age groups. No significant differences in spindle activity of the frontal channels were found between the groups. However, the interindividual spindle variability seemed to be at least as large as that stemming from gender.     

Sleep patterns in college students: gender and grade differences

OBJECTIVE: Since gender effect is inconsistent and grade effect has not been addressed in previous studies, we investigated both effects on the daily sleep patterns in a group of young college students. METHODS: The sample consisted of 237 students aged 18-24 years. Each subject completed a 7-day sleep log. RESULTS: Gender differences were found in several sleep variables and those were mostly not dependent on weekday/weekend difference. The female students went to bed and rose earlier and had longer sleep latency, more awakenings, and poorer sleep quality than the male. Gender differences were also shown in the relationship between sleep quality and other sleep variables. The correlation between sleep quality and rise time, time in bed, and sleep efficiency was stronger in men than in women. In contrast, grade differences were mostly dependent on weekday/weekend difference. The freshmen rose earlier and had shorter sleep time than did the other students on weekdays only. Sleep latency was the longest in seniors on weekdays only. CONCLUSION: This study showed that gender differences in sleep patterns and sleep difficulties were remarkable in the group of young college students. Alarmed by the high prevalence of sleep difficulties among general college students, it is recommended that the students should be informed of their sleep problems and the consequences.     

Antecedents and sex/gender differences in youth suicidal behavior

Suicide is the second leading cause of death in youth globally; however, there is uncertainty about how best to intervene. Suicide rates are typically higher in males than females, while the converse is true for suicide attempts. We review this “gender paradox” in youth, and in particular, the age-dependency of these sex/gender differences and the developmental mechanisms that may explain them. Epidemiologic, genetic, neurodevelopmental and psychopathological research have identified suicidal behaviour risks arising from genetic vulnerabilities and sex/gender differences in early adverse environments, neurodevelopment, mental disorder and their complex interconnections. Further, evolving sex-/gender-defined social expectations and norms have been thought to influence suicide risk. In particular, how youth perceive and cope with threats and losses (including conforming to others’ or one’s own expectations of sex/gender identity) and adapt to pain (through substance use and help-seeking behaviours). Taken together, considering brain plasticity over the lifespan, these proposed antecedents to youth suicide highlight the importance of interventions that alter early environment(s) (e.g., childhood maltreatment) and/or one’s ability to adapt to them. Further, such interventions may have more enduring protective effects, for the individual and for future generations, if implemented in youth.     

Familiality of major depressive disorder and gender differences in comorbidity

Objective: Gender differences exist in the prevalence and psychiatric comorbidity of major depressive disorder (MDD). This study investigates whether familiality of MDD contributes to observed gender differences in comorbidity. Method: Familial (f‐MDD) and non‐familial (nf‐MDD) MDD cases from a population sample were assessed for comorbid dysthymia, anxiety disorders and alcohol‐related disorders using the Composite International Diagnostic Interview (CIDI). Logistic regression analyses were performed to examine the effect of f‐MDD on gender differences in comorbidity, adjusted for confounders. Results: Women with f‐MDD reported significantly more comorbid dysthymia and generalized anxiety disorder (GAD) than their male counterparts; women with nf‐MDD reported significantly more comorbid simple phobias and agoraphobia than their male counterparts. Gender differences in comorbid panic disorder and alcohol‐related disorders occurred independently of the familial load. Adjustment for age of onset, severity and recurrence of MDD did not change these results. Conclusion: Models to explain comorbidity patterns of MDD differ by gender. Familiality of MDD should be taken into account.
