The existential model of perfectionism and depressive symptoms: Tests of incremental validity,gender differences,and moderated mediation

Socially prescribed perfectionism (i.e., perceiving others are demanding perfection of oneself) is a putative vulnerability factor for depressive symptoms. However, there is still much to learn about when and why socially prescribed perfectionists get depressed. Drawing on the existential model of perfectionism and depressive symptoms (EMPDS), we proposed difficulty in accepting the past (i.e., viewing life experiences as coherent, acceptable, satisfying, and meaningful) clarifies when and why socially prescribed perfectionism is linked to depressive symptoms. In the present study of 269 undergraduates (141 men and 128 women), we tested if accepting the past predicts depressive symptoms beyond competing explanations (e.g., self-esteem). And we extended existing research by testing a novel moderated mediation model wherein the strength of the mediated effect of socially prescribed perfectionism on depressive symptoms through accepting the past is stronger at higher levels of socially prescribed perfectionism than at lower levels of socially prescribed perfectionism. We also tested if our results generalized across women and men. Hypotheses were largely supported. Consistent with the EMPDS, our results suggested people high in socially prescribed perfectionism get depressed because they struggle to consolidate their life experiences into a personally meaningful story.     

Midline theta dissociates agentic extraversion and anhedonic depression

The agency facet of extraversion is related to individual differences in reward anticipation and has been linked to the neurotransmitter dopamine. Dopamine has also been associated with components of anhedonia, which is one of the cardinal symptoms of depression and refers to lack of responsiveness to pleasurable stimuli. This raises the question whether low agency is associated with anhedonia symptoms in depression and if agency and anhedonia are characterized by similar neurobiological mechanisms. To address this hypothesis, we tested whether questionnaire measures of agency and anhedonia are correlated within depressed (n = 20) and non-depressed (n = 22) participants. Further, we investigated whether dopamine-related signatures in the EEG recorded during a gambling task (feedback-evoked theta activity, and frontal versus posterior theta activity) similarly relate to agency and anhedonia. Results indicated that anhedonia was significantly elevated in the depression group, and negatively correlated with agency. However, while theta activity evoked by negative vs. positive feedback was sensitive to anhedonia and depression status but unrelated to agency, frontal versus parietal theta activity predicted agency, but was unrelated to anhedonia and depression. Together, this double dissociation suggests that in spite of considerable phenotypical overlap, anhedonia and agency may be linked to partially distinct neurobiological markers.     

Specificity of parental bonding and rumination in depressive and anxious emotional distress

We examined how different dimensions of rumination may mediate the impact of parental bonding (lack of care and overprotectiveness) on negative emotional symptomatology (anxiety and depression). Survey data from participants were analyzed using structural equation modeling. Results indicated that brooding rumination fully mediated the relationship between maternal care and depressive and anxious symptomatology. These findings suggest that to the extent that maternal caregivers are low in warmth and support, offspring are more likely to develop a brooding style of ruminative thinking associated with heightened emotional distress. This research supports the growing body of evidence suggesting that cognitive variables form a pathway between troublesome parent/child interactions and psychopathology.     

Depression mediates the relationship between social performance impairment and hostility

The goal of this study was to test depressive symptoms as a mediator between social difficulties and hostility in young adults. Hostility is often a reaction to both intrinsic and extrinsic factors; therefore a greater understanding of contributing factors is needed, especially among emerging adults. College students (n = 608; 408 females, 200 males) self-reported on social difficulties, depression, and hostility. Via exploratory factor analyses, two latent constructs related to social difficulty were identified: social performance and social motivation. Using structural equation modeling, the direct effects found that poor social performance was significantly positively associated with BPAQ Total (β = .44, p < .01). Social motivation was not associated with BPAQ Total (β = −.07, p = .21). Further, depression scores were found to partially mediate the relationship between social performance deficits (β = .34, p < .01; 95% CI = .05–.16), but not social motivation (β = −.06, p > .05; 95% CI = −.04 to .04), and overall aggression. Results are discussed in terms of the influence of negative affect and impaired emotion regulatory processes on hostility as a consequence of social performance deficits.     

Two pathways to causal control: Use and availability of information in the environment in people with and without signs of depression

Perceiving one's causal control is important for adaptive behavior. Studying depression and other individual differences has provided insight into typical as well as pathological causal processing. We set out to study factors that have been shown to distinguish those with and without signs of depression and affect perceptions of causal control: levels of behavior, the availability of outcomes and learning about the environment or context. Two experiments were carried out in which participants, scoring low and high on the Beck Depression Inventory using established cutoffs, completed a causal control task, in which outcomes occurred with a low (.25) or high probability (.75). Behavior levels were either constrained (N₁ = 73) or unconstrained (N₂ = 74). Overall, findings showed that levels of behavior influenced people's experiences of the context in which events occurred. For all participants, very high behavior levels eliminated sensitivity to levels of outcomes occurring in the environment and lead to judgments that were consistent with conditional probabilities as opposed to the experimenter programmed contingency. Thus increased behavior increased perceived control via influence on context experience. This effect was also evident for those scoring high on the BDI. Overall conclusions are that behavior and context provide two important interlinked psychological pathways to perceived control. However, situations that constrain people's ability to respond freely can prevent people with signs of depression from taking control of a situation that would otherwise be uncontrollable.     

Relationship of posttraumatic growth to symptoms of posttraumatic stress disorder and depression: A pilot study of Iraqi students

Posttraumatic growth (PTG) and psychopathology are common outcomes following exposure to adversity and trauma. We examined the relationship of PTG to posttraumatic stress disorder (PTSD) and depression in a group of young Iraqi students with war trauma exposure. These young Iraqis had experienced an average of 13 different war‐related adversities. The prevalence of probable PTSD was 17.2% and probable depression 23.1%. PTSD was associated with higher and depression with lower PTG. In addition, the relationship between PTG and PTSD was stronger among males than females. Although PTSD and depression were relatively common, they were related to PTG in opposite directions.     

THE IMPACT OF DEPRESSION ON MATERNAL RESPONSES TO INFANT FACES IN PREGNANCY

Research has suggested that prenatal depression may be associated with disrupted maternal responses to infant stimuli, with depressed pregnant women not showing the bias toward distressed infants as that observed in nondepressed pregnant women. The current study examined the effects of depression on self‐ reported responses to infant stimuli, in early pregnancy. Women with clinical depression (n = 38), and nondepressed women (n = 67) were recruited from a wider cognitive behavioral therapy trial. They completed Maternal Response Scales in which they were presented with images of distressed, neutral, and happy infant faces, with no time limit. The women rated their responses to these images along three dimensions—wanting to comfort, wanting to turn away, and feelings of anxiety—using Likert scales via a computerized task. There was evidence that women with depression in pregnancy showed different responses than did women without depression. Women with depression were substantially more likely to be in the highest quartile for ratings of wanting to turn away, odds (OR) ratio = 4.15, 95% confidence intervals (CIs) = 1.63–10.5, p = .003, and also were substantially less likely to be in the highest quartile for wanting to comfort a distressed infant face, OR = 0.22, 95% CIs = 0.09–0.54, p < .001. Findings are consistent with there being both a heightened avoidant and a reduced comforting response toward distressed infants in depressed pregnant women, providing some support that depression disrupts maternal preparations at a conscious level.     

Is the link between autistic traits and ability to succeed in science independent of other psychopathological dimensions?

IntroductionBesides the well-established link between autistic traits and scientific skills, the role of personality in students involved in science has not been thoroughly examined.ObjectiveThis study aimed at reexamining the link between scientific aptitudes and personality, by considering autistic features and other psychopathological dimensions.MethodTwo hundred and ninety-four individuals from French scientific universities answered questionnaires assessing autistic, schizotypal and bipolar dimensions, as well as depressive symptomatology and other variables.ResultsA cluster analysis led to the identification of 4 different groups, among which a cluster was characterized by high scores in autistic, schizotypal and bipolar dimensions. This group, representing nearly 30% of the sample, displayed higher level of depression symptoms (M = 28.5, SD = 12.0) in comparison with other groups (M = 11.7 to 19.1, SD = 5.4 to 9.2). Moreover, the suicidal ideation score was much more important in this cluster (M = 1.6, SD = 2.3) than in the three other groups (M = 0.1 to 0.5, SD = 0.3 to 1.3). This suggested that autistic features, when associated with other personality traits, interfere negatively with the ability of individuals to succeed in science studies, which was partly confirmed by comparing the academic level and results of the different clusters.ConclusionOne may reconsider the link between elevated autistic traits and the ability to accomplish science studies, considering that autistic features are thus frequently associated with other psychopathological traits which may, altogether, lead to depression or other comorbidities negatively interfering with the accomplishment of an academic cursus.     

Prevalence of depressive symptoms and its correlates among medical students in China: a national survey in 33 universities

We conducted a national survey among medical students in China to estimate the prevalence of depressive symptoms and explore associated risk factors based on an established questionnaire composed of demographic information, life events in the past four weeks before survey, and the validated Chinese version of the 21-item Beck’s Depression Inventory (BDI). The mean age of enrolled 9010 students was 20.7 (standard deviation: 1.6) years. BDI scores indicated that 19.9% had depressive symptoms based on the cut-off score of 14. Socioeconomic factors and student characteristics such as male sex, low monthly income per capita, father’s poor education background, and higher year of study were associated with higher prevalence of depressive symptoms among medical students. Students who studied in comprehensive universities were more likely to have depressive symptoms compared with those from medical universities. Habitual smoking and alcohol drinking, sleep deprivation, and hospitalization or medication for one week or more in the last four weeks also predisposed students to higher risk of depressive symptoms. Our results indicate that depressive symptoms are becoming a highly prevalent health problem among Chinese medical students. Primary and secondary prevention should be prioritized to tackle this issue based on potential risk factors.     

Identity and Intimacy Development,Humor Styles,and Psychological Well-Being

This study explored how humor may be involved in the identity and intimacy stages of Erikson’s psychosocial model and also bear on psychological well-being. Participants completed measures of identity and intimacy development, several humor styles, and psychological well-being. Findings revealed that greater identity development was associated with more self-enhancing and affiliative humor use and less self-defeating humor use. Greater intimacy, in turn, was associated with higher affiliative humor and lower self-defeating humor use. Additional findings indicated that the prediction of psychological well-being was significantly enhanced when identity, intimacy, and humor styles were all taken into account. These findings were then considered in terms of specifying the underlying processes that may account for the observed links between identity, intimacy, humor styles, and well-being.
