Temperament as a unifying basis for personality and psychopathology

The role of temperament and character in the anxiety-depression spectrum among Korean adults

BACKGROUND

Temperament and character are useful in risk assessment and therapy of individuals in the anxiety-depression spectrum but understudied in South Korea.

OBJECTIVE

The study aimed to identify the temperament and character features associated with anxiety and/or depression in individuals with clinical disorders and in the general population.

METHODS

A representative sample of 1384 Korean adults over 18 years old (58 % female) were assessed with the Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), and Temperament and Character Inventory (TCI). Multivariate analyses, including structural equation modeling and complex systems analysis, evaluated how personality influenced risk and resilience for anxiety and/or depression.

RESULTS

The three groups with anxiety and/or depression were strongly distinguished by temperament and character: (i) In AD (n = 58), Harm Avoidance and Reward Dependence were higher than in DD, and Self-directedness was higher than in AD+DD; (ii) In DD (n = 90), Persistence, Self-Directedness and Cooperativeness were higher than in AD+DD; and (iii) In AD+DD (n = 101), Harm Avoidance was highest and Persistence and Self-directedness were lowest (i.e., they were lowest in Resilience). Structural equation models confirmed these risk relations with strong character development reducing the adverse effects of emotional hyperreactivity from extreme temperaments.

LIMITATIONS

Self-reports were measured only at one point in time, requiring collateral experimental data to support causal interpretation.

CONCLUSIONS

Interactions of temperament and character are strongly predictive of risk and resilience to anxiety and/or depression by regulating both positive and negative affect. Character mediates the adverse effects of extreme temperaments on affect.

Development of a Culture-Common Formal Characteristics of Behavior - Temperament Markers Inventory (FCB-TMI-CC)

The goal was to create a brief temperament inventory grounded in the Regulative Theory of Temperament (FCB-TMI-CC), with a user-friendly, online applicability for studies in different cultures. As the regulative role of temperament is strongly revealed under meaningful stress, the study was planned within the time of the COVID-19 pandemic. To ensure high diversity in terms of culture, economic and environmental conditions, data from nine countries (Poland, United States of America, Italy, Japan, Argentina, South Korea, Ireland, United Kingdom and Kazakhstan) were utilized (min. N = 200 per country). Validation data were gathered on the level of COVID-19 stressors, posttraumatic stress disorder (PTSD), depression, anxiety and stress symptoms, and Big Five personality traits. Multigroup confirmatory factor analysis served as the basis for the inventory's construction. The final culture-common version includes 37 items (5-6 in each of the 7 scales) and covers the core aspects of temperament dimensions. Temperament structure was confirmed to be equivalent across measured cultures. The measurement is invariant at the level of factor loadings and the reliability (internal consistency) and theoretical validity of the scales were at least acceptable. Therefore, the FCB-TMI-CC may serve as a valuable tool for studying temperament across diverse cultures and facilitate cross-cultural comparisons.

Course of avoidant/restrictive food intake disorder: Emergence of overvaluation of shape/weight

BACKGROUND

Avoidant/restrictive food intake disorder (ARFID) is a feeding/eating disorder characterized by avoidance/restriction of food intake by volume and/or variety. The emergence of shape/weight-related eating disorder symptoms in the longitudinal course of ARFID is an important clinical phenomenon that is neither robustly documented nor well understood. We aimed to characterize the emergence of eating disorder symptoms among adults with an initial diagnosis of ARFID who ultimately developed other eating disorders.

METHOD

Thirty-five participants (94% female; Mage = 23.17 ± 5.84 years) with a history of ARFID and a later, separate eating disorder completed clinical interviews (i.e., Structured Clinical Interview for DSM-5 - Research Version and Longitudinal Interval Follow-Up Evaluation) assessing the period between ARFID and the later eating disorder. Participants used calendars to aid in recall of symptoms over time. Descriptive statistics characterized the presence, order of, and time to each symptom. Paired samples t-tests compared weeks to emergence between symptoms.

RESULTS

Most participants (71%) developed restricting eating disorders; the remainder (29%) developed binge-spectrum eating disorders. Cognitive symptoms (e.g., shape/weight concerns) tended to onset initially and were followed by behavioral symptoms. Shape/weight-related food avoidance presented first, objective binge eating, fasting, and excessive exercise occurred next, followed by subjective binge eating and purging.

CONCLUSIONS

Diagnostic crossover from ARFID to another (typically restricting) eating disorder following the development of shape/weight concerns may represent the natural progression of a singular clinical phenomenon. Findings identify potential pathways from ARFID to the development of another eating disorder, highlighting possible clinical targets for preventing this outcome.

Meta-Analytic Review of Temperamental Correlates of the Five-Factor Model and Hierarchical Taxonomy of Psychopathology Domains

Background

There is little and heterogeneous knowledge on the links between the temperamental predispositions of psychopathology and the contemporary dimensional models of psychopathology, such as the Hierarchical Taxonomy of Psychopathology (HiTOP) classification system, which can be aligned with the five-factor model (FFM) of personality. This meta-analysis seeks to expand the temperamental theoretical basis of the HiTOP model by incorporating associations of temperament traits of two temperamental theories measured, respectively, by the Temperament and Character Inventory (TCI) and the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPS-A) with (a) the FFM's personality domains and (b) HiTOP's five psychopathological spectra.

Methods

A systematic search was done on Web of Science, Scopus, PubMed, ProQuest, Cochrane Database, and Google Scholar for all articles published in English from January 1990 to August 2020. Because of heterogeneity in the results of almost 70% of studies, pooled estimates of correlation coefficients were calculated using the random-effects method. Risk of bias (low-quality studies) and publication bias are reported.

Results

The pooled correlations obtained from the analysis of 35 studies showed that the temperamental profile associated with each FFM domain and HiTOP spectra is distinct. Specifically, TCI-harm avoidance (HA) and all TEMPS temperaments were more strongly related to neuroticism/internalizing, extraversion/low detachment, and conscientiousness/disinhibition. In contrast, TCI-novelty seeking was more strongly related to both disinhibited/antagonistic externalizing and thought disorder.

Conclusions

A large body of research supports maladaptive variants of all FFM domains and some psychopathological spectra of HiTOP related to the abnormal-range temperaments.

The Relationship Between Emotion Dysregulation and Error Monitoring in Adolescents with ADHD

Attention-deficit/hyperactivity disorder (ADHD) is emblematic of the limitations of existing diagnostic categories. One potential solution, consistent with the Research Domain Criteria (RDoC) initiative, is to interrogate psychological mechanisms at the behavioral and physiological level together to try and identify meaningful subgroups within existing categories. Such approaches provide a way to revise diagnostic boundaries and clarify individual variation in mechanisms. Here, we illustrate this approach to help resolve heterogeneity in ADHD using a combination of behaviorally-rated temperament measures from the Early Adolescent Temperament Questionnaire; cognitive performance on three difference conditions of an emotional go/no-go task; and electroencephalogram (EEG)-measured variation in multiple stages of error processing, including the error-related negativity (ERN) and positivity (Pe). In a large (N = 342), well-characterized sample of adolescents with ADHD, latent profile analysis identified two ADHD temperament subgroups: 1) emotionally regulated and 2) emotionally dysregulated (with high negative affect). Cognitive and EEG assessment in a subset of 272 adolescents (nADHD = 151) found that the emotionally dysregulated group showed distinct patterns of change in early neural response to errors (ERN) across emotional task conditions as compared to emotionally-regulated ADHD adolescents and typically-developing controls. Both ADHD groups showed blunted later response to errors (Pe) that was stable across emotional task conditions. Overall, neural response patterns identified important differences in how trait and state emotion interact to affect cognitive processing. Results highlight important temperament variation within ADHD that helps clarify its relationship to the ERN, one of the most prominent putative neural biomarkers for psychopathology.

Deep CANALs: a deep learning approach to refining the canalization theory of psychopathology

Psychedelic therapy has seen a resurgence of interest in the last decade, with promising clinical outcomes for the treatment of a variety of psychopathologies. In response to this success, several theoretical models have been proposed to account for the positive therapeutic effects of psychedelics. One of the more prominent models is "RElaxed Beliefs Under pSychedelics," which proposes that psychedelics act therapeutically by relaxing the strength of maladaptive high-level beliefs encoded in the brain. The more recent "CANAL" model of psychopathology builds on the explanatory framework of RElaxed Beliefs Under pSychedelics by proposing that canalization (the development of overly rigid belief landscapes) may be a primary factor in psychopathology. Here, we make use of learning theory in deep neural networks to develop a series of refinements to the original CANAL model. Our primary theoretical contribution is to disambiguate two separate optimization landscapes underlying belief representation in the brain and describe the unique pathologies which can arise from the canalization of each. Along each dimension, we identify pathologies of either too much or too little canalization, implying that the construct of canalization does not have a simple linear correlation with the presentation of psychopathology. In this expanded paradigm, we demonstrate the ability to make novel predictions regarding what aspects of psychopathology may be amenable to psychedelic therapy, as well as what forms of psychedelic therapy may ultimately be most beneficial for a given individual.

Using Dispositions to Understand Otherwise Intractable Causal Pathways to Psychological Problems During Childhood and Adolescence

Studies of the genetic and environmental factors that make children more or less likely to develop distressing and impairing psychological problems, and studies of the psychobiological pathways through which these causal factors operate, have the goal of improving our understanding of the basic nature of psychological problems to develop better methods of prevention and treatment. For this reason, we have long had our eye on the prize of discovering the causes and psychobiological mechanisms underlying each dimension of psychological problems. There are compelling reasons, however, to seek a different and more achievable prize to understand psychological problems. Dimensions of psychological problems are both far too heterogeneous and too highly correlated to line up with distinct causal pathways. In contrast, a small number of orthogonal cognitive and socioemotional dispositional dimensions are correlated with psychological problems in revealing cross-cutting patterns. Each of these dispositions shares its independent causal pathways with psychological problems and help us understand the complex shared and heterogeneous nature of their causal processes. I outline a strategy for understanding the causes and mechanisms of psychological problems using studies of independently measured dispositions.

The association between personality, relationship satisfaction, and psychopathology in a three-wave, longitudinal study

OBJECTIVE

The aim of this work was to better understand the role of personality as it relates to psychopathology, with satisfaction as a mediating variable.

BACKGROUND

Personality is an important determinant of many life outcomes including relationship satisfaction and psychopathology. Previous work has demonstrated that broad domains of normal personality have low-to-moderate associations with various forms of psychopathology. Research has primarily focused on mechanisms that might explain how common personality traits put one at risk for common forms of psychopathology; this work builds upon existing work in examining relationship satisfaction as one possible mechanism. No study to date has examined whether relationship satisfaction mediates the connection between personality and psychopathology.

METHOD

We utilized multilevel modeling in a longitudinal sample of 100 newlywed couples to test the hypothesis that major domains of personality (positive temperament, negative temperament, disinhibition) have a significant effect on relationship satisfaction which, in turn, is significantly associated with internalizing and externalizing forms of psychopathology.

RESULTS

We found no evidence for the mediating role of relationship satisfaction; however, in exploratory analyses, we did find evidence for both between-person and within-person effects of personality on psychopathology.

CONCLUSIONS

This study confirms the role of personality as an important factor in consideration of dyadic processes, though not entirely deterministic for downstream functioning. Thus, separate factors in addition to personality may be worth examining in consideration of how low relationship satisfaction may be associated with psychopathology.

Disinhibition domain and facets uniquely predict changes in depressive symptoms and psychosocial functioning

This study aimed to understand the role of disinhibition (low conscientiousness)-in conjunction with the other major personality traits of negative affectivity, detachment, antagonism, and psychoticism-in predicting changes in depressive symptoms and psychosocial functioning. Both the disinhibition trait domain and its primary facets (i.e., irresponsibility, impulsivity, and distractibility) were examined. In a large sample (Time 1 N = 605, Time 2 N = 497) of psychiatric outpatients and high-risk community residents, personality traits, depressive symptoms (both self-reported and interviewer-rated), and psychosocial functioning levels (i.e., daily functioning, interpersonal functioning, health-related quality of life, and global quality of life) were collected across two time points. Results showed that the disinhibition domain was the strongest predictor of changes in depressive symptoms and general quality of life levels. Disinhibition facets also predicted changes in depressive symptoms but showed a less consistent pattern compared to the broader trait domain. Finally, the irresponsibility and distractibility facets significantly and uniquely explained changes in interpersonal functioning. The study highlights the importance of assessing the disinhibition trait rather than only negative and positive affectivity (which are well-known correlates of depression), for understanding changes in depressive symptoms and psychosocial functioning. The findings identify potential targets in psychotherapy for individuals with disinhibition traits and depressive disorders.

Psychiatric comorbidity: a concept in need of a theory

Despite being a relatively new concept, psychiatric comorbidity, i.e. the co-occurrence of two or more mental disorders, has become widespread in clinical practice and psychiatric research. In this article, we trace the origin of the concept of psychiatric comorbidity, discuss the conceptual literature and point to basic problems concerning inadequate definition of the concept, differential diagnostic issues, and reification of mental disorders. We illustrate how these problems may have consequences for diagnostic assessment in current clinical practice and psychiatric research. To address some of the problems related to psychiatric comorbidity, we discuss potential principles for assessing psychiatric comorbidity. Inspired by Feinstein's original concept of comorbidity in general medicine and his differential diagnostic principles, we emphasize the importance of independence of mental disorders when assessing psychiatric comorbidity. We suggest that knowledge of trait v. state conditions and of the multitudinous clinical manifestations beyond what is captured in the diagnostic manuals may be helpful for assessing the independence of mental disorders and thus psychiatric comorbidity. We further argue that a more hierarchical diagnostic system and explicit exclusionary rules could improve clinical practice and research by reducing informational complexity and combating unwarranted psychiatric comorbidity.

Offspring irritability: associations with parental psychopathology and personality

Although there are well-established correlates and outcomes of irritability, there are fewer studies reporting on predictors of the longitudinal course of irritability in youth. The current report examined parent internalizing and externalizing psychopathology and dimensions of personality as predictors of the developmental course of irritability in youth. Offspring irritability was assessed between ages 2 and 10 years using the Irritability Factor from the parent-reported Child Behavior Checklist (N = 570, 53.51% female). Parental psychopathology was assessed with a clinical interview; parents also completed the General Temperament Survey as a measure of personality. Results demonstrated that offspring irritability decreased with age. Offspring irritability was associated with parental depressive and anxiety disorders, higher levels of negative emotionality/neuroticism (NE) and disinhibition, and lower levels of positive emotionality; parental NE and disinhibition remained unique predictors of offspring irritability in a multivariate model. Finally, parental externalizing disorders were associated with more stable trajectories of offspring irritability, whereas offspring of parents without a history of externalizing disorders showed decreasing irritability across time. Findings demonstrate that different aspects of parental personality and psychopathology have differential impacts on levels and course of offspring irritability.

Validity of a Revised Obsessive-Compulsive Personality Disorder (OCPD) Trait Profile and Its Relationship with Social Interaction Anxiety and Coping

There is evidence suggesting that the conceptualization and operationalization of Obsessive-Compulsive Personality Disorder (OCPD) is not satisfactory (Watters et al., 2019). In this study, we used an online sample (N = 1008) to investigate the construct validity of the PID-5 OCPD trait measure. Regression analyses supported our hypothesis that rigid perfectionism captured the core phenomenology of OCPD whereas restricted affectivity and intimacy avoidance were not conceptually related to the OCPD construct. Based on the biosocial theory for overcontrol (Lynch, 2018), we introduced anxiousness and workaholism to the PID-5 OCPD trait profile. In establishing the validity of the revised OCPD trait profile, we investigated, for the first time, the role of social interaction anxiety and maladaptive coping in OCPD. Our revised OCPD profile showed good validity and was characterized by marked social interaction anxiety and dysfunctional coping mechanisms. The findings may lead to a new conceptualization of OCPD which prioritizes deficits in social interaction and coping. We identify areas that need to be prioritized in the evaluation of OCPD by mental health professionals and offer avenues for new clinical research in the field.

The Role of Shame in Schizophrenia Delusion: The Interplay Between Cognitive-Perceptual and Emotional Traits

ABSTRACT

Through a strictly dimensional approach, the present study aimed at evaluating the interplay between cognitive-perceptual disturbances and emotional dispositions, particularly shame proneness, in schizophrenia delusion. One hundred one outpatients with schizophrenia were administered the Peters et al. Delusions Inventory, the Referential Thinking Scale (REF), the Magical Ideation Scale (MIS), the Perceptual Aberration Scale (PAS), the Positive and Negative Affect Schedule and the Experiences of Shame Scale (ESS). The severity of delusional ideation was positively related to all the cognitive-perceptual scales (REF, MIS, and PAS) and to shame proneness (ESS). Referential thinking (REF) emerged as the strongest predictor of delusion severity. The experience of shame played a mediation role in the relationship between cognitive-perceptual traits and delusional severity. These data suggest that severity delusion in schizophrenia depends, at least in part, on a complex interplay between cognitive-perceptual disturbances and experiences of shame.

Relative Effects of Sexual Assault and Temperament Traits on Cognitive Characteristics of Histrionic Personality Disorder

Histrionic personality disorder (HPD) is a common and problematic form of personality pathology involving excessive attention-seeking, often through overly sexualized means. Much of the research on HPD has involved the association between HPD characteristics and basic temperament traits. Given the sometimes hypersexualized presentation of HPD, another potential influence on HPD characteristics may be exposure to sexual assault. However, there is little research on the association between sexual assault and HPD in general or with respect to temperament traits in particular. In this study, we examine the relative associations of sexual assault and temperament traits with the cognitive characteristics of HPD in a large sample of college students (N = 965) using a Bayesian approach to the analysis of covariance. Results suggest that sexual assault is associated with HPD cognitive characteristics over and above the robust influence of temperament traits. The study findings have implications for future research on and clinical intervention with people with HPD.

Tracing the evolution of personality cognition in early human civilisations: A computational analysis of the Gilgamesh epic

Assessing evolution of cognitive structures across historical periods has remained challenging in the absence of direct access to humans from the past. Overcoming some of these challenges, we examined shifts in the implicit cognitive structures in the Epic of Gilgamesh, which is one of the earliest surviving pieces of literature, circulating in various versions over a period of approx. 2000 years in ancient Mesopotamia. Using a canonical English translation, we applied natural language processing (NLP) and human coding to extract low-dimensional representations of the implicit personality structure in three different historical epochs. We found systematic shifts over time with increasing complexity and increasing resemblance of contemporary personality models in later periods. We discuss how lexical analyses of ancient texts using trait co-occurrence analyses can provide novel insights on the evolution of human behaviour of relevance for contemporary social and behavioural science and the study of ancient societies.

Emotion-related impulsivity and risky decision-making: A systematic review and meta-regression

Emotion-related impulsivity, the trait-like tendency toward regrettable behavior during states of high emotion, is a robust predictor of internalizing and externalizing psychopathology. Despite substantial evidence that emotion-related impulsivity is important transdiagnostically, relatively little is known about its cognitive correlates. This systematic review and meta-regression investigates one such candidate, risky decision-making. We analyzed 195 effect sizes from 51 studies of 14,957 total participants, including 105 newly calculated effect sizes that were not reported in the original publications. The meta-regression demonstrated evidence for a small, positive relationship of emotion-related impulsivity with behavioral indices of risky decision-making (ß = 0.086). Effects generalized across sample age, gender, Positive versus Negative Urgency, and clinical versus nonclinical samples. The average effect size varied by task type, with stronger effects for the Iowa Gambling Task and Delay Discounting Task. Experimental arousal manipulation was nearly a significant moderator, with stress and pharmacological manipulations yielding significant effect sizes. Analyses indicated that publication bias did not skew the current findings. Notwithstanding limitations, the data suggest that risky decision-making is a cognitive domain that relates to emotion-related impulsivity. We conclude with recommendations regarding the specific types of tasks and arousal inductions that will best capture emotion-related impulsivity in future experimental research.

Temperament traits mediate the relationship between CACNA1C polymorphisms and bipolar disorder in cisgender women

The influence of temperament traits on bipolar disorder (BD) has been investigated. Both temperament traits and BD are partially genetically determined and seem to be influenced by variations in the CACNA1C gene. These variations presented a significant interactive effect with biological sex, although studies that evaluate this relationship are scarce. Here, we assessed the mediation effect of temperament traits on the relationship between two polymorphisms in the CACNA1C gene (rs1006737 and rs4765913) and BD according to sex. This is a cross-sectional study consisting of 878 Caucasian individuals (508 women and 370 men), aged 18-35, enrolled in a population-based study in the city of Pelotas, Southern Brazil. BD diagnosis was evaluated using the clinical interview MINI 5.0, and temperament traits were assessed via the application of the Affective and Emotional Composite Temperament Scale (AFECTS). Mediation models were tested using the modeling tool PROCESS (version 3.3) for SPSS. Bootstrapping-enhanced mediation analyses in women indicated that traits anger (39%) and caution (27%) mediated the association between the rs4765913 SNP and BD, while traits volition (29%), anger (35%), and caution (29%) mediated the association between the AA haplotype (rs1006737-rs4765913) and the BD. No effect was encountered for cisgender men. Our model revealed that paths from CACNA1C SNPs to BD are mediated by specific temperament traits in women, reinforcing the definition of temperament traits as endophenotypes.

Validation of the Arabic version of the 35-item TEMPS-M in a community sample of adults

BACKGROUND

To our knowledge, no brief version of the Temperament Evaluation in Memphis Pisa and San Diego (TEMPS-M) is available so far in the Arabic language, which might have resulted in limited research in this field from Arab countries. We aimed through this study to validate the 35-item TEMPS-M into the Arabic language in a sample of non-clinical Lebanese adults.

METHODS

We used an online cross-sectional survey targeting non-clinical Lebanese adults from the general population. A confirmatory factor analysis was conducted to test the factorial structure of the TEMPS-M.

RESULTS

All five temperament subscales achieved good/very good internal consistencies in the present study (depressive: α = 0.78, cyclothymic: α = 0.86, hyperthymic: α = 0.83, irritable: α = 0.87, and anxious: α = 0.87). The five-factor solution of the TEMPS-M displayed a good CFI of 0.94, TLI of .94 and a GFI of .95, but a poor RMSEA of .10 [90% CI .10, .11]. The five affective temperaments showed positive correlations with personality dysfunction domains, thus attesting for convergent validity. In addition, positive correlations between all affective temperament dimensions and anxiety/depression scores were found. We also tested for gender invariance, and found that configural, metric, and scalar invariance were supported across gender.

CONCLUSION

Our data suggest that the psychometric properties of the Arabic TEMPS-M are good. Making this scale available in Arabic will hopefully encourage Arab researchers to investigate this under-explored topic in their countries, and advance knowledge on how culture impacts the prevalence, development and course of temperament.

Sex-specific psychological risk profiles of CVD in the HUNT study: the role of neuroticism and extraversion

OBJECTIVE

The aim was to investigate psychological risk profiles of cardiovascular disease (CVD). Depression and anxiety have been linked to CVD, but research has not incorporated personality and sex-specific analyses are warranted. In this study, we examine the role of sex, neuroticism, extraversion, anxiety and depression on the risk of CVD.

METHOD

Using data from the HUNT-study and the mortality register, 32,383 (57.10% men) participants were followed for an average of 10.48 years. During this time, 142 died of myocardial infarction (MI) and 111 of stroke.

RESULTS

Cox regression showed that depression (HR = 1.07, 95% CI = [1.00, 1.14]) and neuroticism (1.23 [1.08, 1.40]) were significantly related to an increased risk of MI. One standard unit increase in depression and neuroticism was associated with 1.22 [CI 1.01, 1.47] increase and 1.43 [CI 1.14, 0.78] increase in the risk of MI respectively. For stroke, there was no significant effect of anxiety, depression or personality. However, we found a significant interaction effect between sex and extraversion where higher extraversion was associated with greater risk of stroke for women only.

CONCLUSIONS

Both neuroticism and depression were related to MI. We observed an interaction between extraversion and sex with stroke, but the effect size was small. The role of extroversion as a risk factor for CVD remains inconclusive.

Neighborhood Disadvantage and Mental Health: Test of a Parallel Mediation Model through Social Support and Negative Emotionality

According to the life stress model, stressful circumstances occur in the context of social, psychological, and environmental features that can function as either resources or aggravating factors, each of which are associated with well-being. This research was designed to test indirect effects of living in disadvantaged neighborhoods on mental health, through reduced social support and increased negative emotionality. This model was tested with data from a national sample of 1050 adults residing in the United States. Participants completed measures of social support, negative emotionality, depression, loneliness, stress, and alcohol consumption. These scores were merged with data from the 2015 American Community Survey to assess indicators of neighborhood disadvantage at the zip code level. The test of a parallel mediation model with structural equation modeling indicated that neighborhood disadvantage did not have direct effects on either psychological distress or alcohol consumption. However, neighborhood disadvantage was associated with greater negative emotionality, and through negative emotionality, exhibited indirect effects on psychological distress and alcohol consumption. These results are consistent with elements of the life stress model that specify various psychosocial traits as maladaptive in the context of stressful environments.

Associação entre Temperamento e o Uso de Práticas da Medicina Alternativa e Complementar

Resumo Trata-se de um estudo brasileiro, transversal, mediado pela Internet com o objetivo de descrever como diferenças temperamentais associam-se ao uso de oito práticas de medicina alternativa e complementar (MAC): ioga, meditação, reiki, acupuntura, massagem, tai chi chuan, homeopatia e floral. A amostra foi composta por 22.415 indivíduos, sendo 69,5% mulheres, com idade média de 28,8 anos (DP = 9,1). As práticas mais utilizadas foram massagem e ioga e as variáveis sexo, idade, renda e diagnóstico psicopatológico ao longo da vida associaram-se a todas as práticas, exceto com tai chi chuan. Análise inferencial se baseou em modelo de regressão logística e os resultados foram calculados com base na razão de chances com intervalo de confiança de 95%. Observou-se que manifestações adaptativas de traços e de tipos psicológicos, associaram-se a maiores chances de praticar MAC. Resultados sugerem que perfis com maior regulação emocional tendem a utilizar mais frequentemente MAC e, possivelmente, obter benefícios.

A multimethod, multiinformant study of early childhood temperament and depression and anxiety symptoms in adolescence

There is an extensive literature documenting associations between dimensions of temperament and depressive and anxiety disorders. However, much of the research in this area relies on cross-sectional and monomethod designs, uses samples of older youth and adults, and examines only the main effects of temperament. We examined longitudinal associations between temperamental positive emotionality (PE) and negative emotionality (NE) in early childhood and depressive and anxiety symptoms in adolescence. We assessed temperament using laboratory observations and parent reports, and symptoms using youth and parent report. We also examined potential moderators of these associations, including maternal and paternal history of depressive and anxiety disorders, youth experience of stressful life events, and parenting styles. Early childhood NE was associated with both adolescent depression and anxiety. Additionally, life events and psychological controlling and firm parenting moderated the associations between NE and depression symptoms, and maternal depression, paternal anxiety, and psychological controlling and firm parenting moderated the associations between NE and anxiety symptoms. Interaction effects were largely consistent with diathesis-stress interpretations. These findings show that temperamental NE, but not PE, is prospectively associated with risk for depressive and anxiety symptoms in adolescence, and that multiple additional factors potentiate these associations.

The Mediating Role of Extra-family Social Relationship Between Personality and Depressive Symptoms Among Chinese Adults

Objectives: This study aims to explore the associations of personality traits and extra-family social relationship with depressive symptoms among Chinese adults.

Methods: A nationally representative sample of 29,810 adults aged 16 and above were selected from 2018 CFPS. Personality and depressive symptoms were measured using CBF-PI-15 and the CES-D8 scale. Extra-family social relationship was assessed through the self-rated evaluation. The multiple regression analysis and the PROCESS macro were used for the mediation analysis.

Results: Extraversion (OR = 0.807, 95% CI = 0.773, 0.842), agreeableness (OR = 0.795, 95% CI = 0.756, 0.835) and extra-family social relationship (OR = 0.927, 95% CI = 0.913, 0.941) had negative associations with depressive symptoms. Extra-family social relationship could mediate between extraversion and depressive symptoms (Indirect effect = −0.049,95% CI = −0.060, −0.039) as well as agreeableness (Indirect effect = −0.056, 95% CI = −0.068, −0.046) and depressive symptoms. Comparing to females, the indirect effect accounts for a higher proportion of total effect in males.

Conclusion: Extra-family social relationship might mediate the association between extraversion and depressive symptoms as well as agreeableness and depressive symptoms.

Effects of Smoking on Aggression, Big Five Personality Factors, and Polymorphisms in HTR2A, DRD4, and MAOA among Egypt University Students

Introduction

To find genetic variants in the DRD4 and HTR2A genes' promoter regions and exons that are associated with tobacco smoking and nicotine addiction in Egyptian university students as well as to study the association between personality traits and smoking status.

Methods

A self-administered questionnaire about cigarette smoking and personality attributes (Big Five Inventory, ESPAD Questionnaire on Substance Abuse, and Buss-Perry Aggression Questionnaire). The participants in the study were 90 nonsmokers (NS) and 88 current smokers (CS), who were divided into two groups depending on their cigarette consumption per day (cpd): 55 heavy smokers (HS, >20 cpd) and 33 light smokers (LS, 1–10 cpd). Four and eight single nucleotide polymorphisms (SNPs) in the DRD4, HTR2A, and MOA genes, respectively, were genotyped.

Results

Smokers scored lower on neuroticism, agreeableness, conscientiousness, openness, and extraversion than nonsmokers, but higher on aggression. Furthermore, the C allele of rs1800955 in DRD4 was associated with cigarette smoking in the HS vs. NS and LS vs. NS studies. The T allele of the HTR2A rs6313 gene was discovered to be strongly associated with cigarette smoking. There was no link discovered between MOA rs1137070 and MOA rs1137070.

Conclusions

Using a comprehensive personality model (FFM), this study repeats and extends earlier research. Personality and genetic studies may aid in the development of a more complete and conclusive understanding of cigarette smoking, as well as more precise policies and guidelines for smoking cessation and quitting.

Temperaments and orthorexia nervosa: a cross-cultural study between Germany and Lebanon

The aim of this study was to explore the association between affective temperaments and orthorexic eating and whether temperament may explain cross-cultural differences in this behavior while considering the two dimensions of orthorexic eating, healthy (HeOr) and nervosa (OrNe). To accomplish this, 337 and 389 individuals were recruited in Lebanon and Germany, respectively. The brief version of the Temperament Evaluation of Memphis, Pisa, Paris and San Diego explored depressive, hyperthymic, cyclothymic, anxious and irritable temperaments, and the Teruel Orthorexia scale explored orthorexic eating. HeOr appeared comparable between countries but OrNe was higher in Lebanon. In terms of affective temperaments, the higher the depressive, cyclothymic, irritable, and anxious temperaments, the higher were the levels of OrNe. Only the hyperthymic temperament scale was positively associated with HeOr. Three-step regression analysis indicated only gender as a unique predictor for HeOr. By contrast, gender, depressive, hyperthymic, and anxious temperament as well as the two-way interactions country*depressive temperament and country*hyperthymic temperament were significant predictors of OrNe. The positive association between OrNe and depressive temperament was only found for the German sample while the negative association between hyperthymic temperament and OrNe was somewhat stronger in the Lebanese sample. Overall, a higher healthy interest in diet was linked to the hyperthymic temperament. Findings emphasized the role of temperaments in pathological orthorexic eating in general as well as in explaining cross-cultural differences in these behaviors. The assessment of temperaments could help to fit treatments for eating pathologies to individuals from different cultures, focusing interventions more on these aspects.

The Clinical Relevance of a Socioecological Conceptualization of Self-Worth

Low self-worth pervades discussions of psychopathology, is a central feature of many psychiatric disorders, and appears in conceptions of psychological distress in a range of cultural contexts . Explication of this aspect of self-evaluation offers clinical utility especially when adequate attention is paid to social and cultural aspects of the self. In this paper, we propose that refining the conceptualization of self-worth as felt perceptions of one’s mattering and deservingness of equity and psychological, social, and material resources offers a unique clinical utility. We present an argument for this definition of self-worth, building on existing literature, as a relativistic construct informed and reinforced by dynamic feedback from intrapersonal, interpersonal, sociocultural, and structural socioecological levels. To highlight that self-worth has been an implied but under-examined concept, we follow with a selective review of psychological and sociological perspectives of self-esteem and related constructs. We conclude with a discussion of our conceptualization’s implications for measurement and treatment, including the potential transdiagnostic utility of self-worth.

Cortical thickness in parietal regions link perseverative thinking with suicidal ideation

INTRODUCTION

Suicide represents a major public health concern, as the tenth leading cause of death in the United States. Links between perseverative thinking (PT) and suicidal ideation have previously been examined, while their biological underpinnings remain understudied. The present study had two aims: 1) investigate whether cortical thickness varied as a function of PT, and 2) examine whether variation in thickness partially explained associations between PT and lifetime history of ideation. We hypothesized that cortical thickness would vary as a function of PT and PT would be positively associated with lifetime history of ideation.

METHODS

A community sample of 73 adults (ages 18-55; 42.5% female) completed self-report measures examining PT and ideation, as well as a neuroimaging protocol. Mean scores on the Perseverative Thinking Questionnaire were entered as the explanatory variable in the analysis of cortical thickness clusters related to PT. The indirect effect of PT on ideation through thickness was tested cross-sectionally.

RESULTS

PT was positively associated with i) thickness in three clusters bilaterally in the parietal cortex and ii) suicidal ideation. Follow-up analyses revealed a significant indirect effect of PT on suicidal ideation through left superior parietal thickness.

LIMITATIONS

Limitations of the study include the use of cross-sectional data and a modest sample size.

CONCLUSIONS

PT is associated with variations in cortical thickness, and increased thickness in the left parietal region may partially explain the link between PT and suicidal ideation, identifying a novel neurobiological mechanism of ideation.

Association between resilience, social support, and institutional trust and post-traumatic stress disorder after natural disasters

Disasters can cause significant personal and social distress and adversely affect mental health. Compared with research on the risk factors of post-disaster post-traumatic stress disorder (PTSD), limited studies have reported protective factors against PTSD. We investigated whether resilience, social support, and trust in government were associated with PTSD in disaster survivors, after adjustment for the perceived damage and demographic variables including sex, age, and economic status. We investigated 2311 disaster survivors, using data from the "Long-term survey on the change of life of Disaster victim" performed by NDMI(National Disaster Management Research Institute). Hierarchical regression analysis was used in this study. A high level of trust in institutions was associated with few PTSD symptoms after adjustment for resilience and social support. Among the subfactors of institutional trust, psychological counseling and environmental and facility restoration were associated with PTSD. Psychological counseling and environmental and facility restoration support for disaster survivors were associated with reduced PTSD symptoms. Post-disaster policy support, including psychological counseling and environmental and facility restoration services, is important. Our findings highlight the protective factors against PTSD symptoms and may serve as guidelines for specific interventions for the management of post-disaster PTSD.

Latent stability and change in subgroups of social anxiety and depressive symptoms in adolescence: A latent profile and transitional analysis

BACKGROUND

Social anxiety and depressive symptoms increase markedly during adolescence. Most research examining the emergence of these symptoms has used a variable-centered approach providing little information about how these symptoms group together in individuals over time.

METHOD

A person-centered approach utilizing latent profile and latent transitional analyses was applied to a large adolescent sample (N = 2742, M_age=13.65; SD=0.63; 47.9% girls). Subgroups differing in their expressions of social anxiety and depressive symptoms at each of four annual time points were identified and then change in membership of these groups was evaluated.

RESULTS

Four subgroups were identified: 1. Low Distress, 2. Socially Anxious, 3. Dysphoric, and 4. Comorbid. The low distress group was the largest and most stable, followed by the socially anxious group, who most commonly transitioned into the comorbid group. In contrast, the dysphoric group were most likely to remit and move to the low distress group. The comorbid group was the smallest and least stable, although once in this group, three quarters of adolescents remained in this group over time.

CONCLUSION

Early intervention is particularly imperative for socially anxious adolescents with or without comorbid depressive symptoms as they are the least likely to improve across the adolescent years.

Reinforcement sensitivity predicts affective psychopathology via emotion regulation: Cross-sectional, longitudinal and quasi-experimental evidence

The current article presents a model wherein reinforcement sensitivity predicts depression and anxiety via trait preferences for concomitant emotion regulation strategies. In Study 1 (N = 593), BAS sensitivity positively predicted reappraisal and BIS sensitivity negatively predicted it. Reappraisal then negatively predicted depression. BIS sensitivity also predicted rumination, which predicted both depression and anxiety. Study 2a confirmed the model developed in Study 1 with an independent sample (N = 513) and examined the relationships longitudinally. While the cross-sectional relationships were generally maintained, reinforcement sensitivity did not predict reappraisal. In Study 2b, participants (N = 218) were assessed a third time one year later, at the onset of the COVID-19 pandemic. During this stressful time, BAS sensitivity did longitudinally predict reappraisal. These studies highlight the role of emotion regulation in mediating the relationship between reinforcement sensitivity and affective pathology, particularly during times of high stress.

Emotion-related impulsivity: Testing a model of arousal effects on cognitive control

The trait-based tendency to respond rashly to emotions is robustly tied to many forms of psychopathology and poor behavioural outcomes, including aggression and suicidality. Researchers have found associations between response inhibition and emotion-related impulsivity; however, effect sizes are often small. Because emotion-related impulsivity emerges in the context of heightened positive and negative emotions, arousal is a candidate trigger of impulsivity. The goals of the present study were to (1) replicate the association between emotion-related impulsivity and response inhibition, and (2) test whether emotion-related impulsivity is associated with arousal-induced decays in response inhibition performance. Participants (N = 55) completed a self-report measure of emotion-related impulsivity, and then completed a computer-based response inhibition task (the antisaccade task, in which participants must make a rapid saccadic eye movement away from a cue rather than toward it) before and after a well-validated stress induction (the Trier Social Stress Test). Psychophysiological indices of arousal were measured throughout the session. Findings provide partial support for the association between emotion-related impulsivity and pre-stress response inhibition. Contrary to hypotheses, emotion-related impulsivity did not interact with arousal to predict post-stress response inhibition performance after controlling for pre-stress response inhibition performance. Future research is needed to consider clinical samples and to assess whether emotion-related impulsivity is related to deficits in other facets of cognitive control and decision-making.

Psychopathy: Current Knowledge and Future Directions

Research on psychopathy has progressed considerably in recent years against the backdrop of important advances in the broader field of clinical psychological science. My major aim in this review is to encourage integration of investigative work on dispositional, biobehavioral, and developmental aspects of psychopathy with counterpart work on general psychopathology. Using the triarchic model of psychopathy as a frame of reference, I offer perspective on long-standing debates pertaining to the conceptualization and assessment of psychopathy, discuss how dispositional facets of psychopathy relate to subdimensions of internalizing and externalizing psychopathology, and summarize findings from contemporary biobehavioral and developmental research on psychopathy. I conclude by describing a systematic strategy for coordinating biobehavioral-developmental research on psychopathy that can enable it to be informed by, and help inform, ongoing research on mental health problems more broadly. Expected final online publication date for the Annual Review of Clinical Psychology, Volume 18 is May 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Validity and utility of Hierarchical Taxonomy of Psychopathology (HiTOP): III. Emotional dysfunction superspectrum

The Hierarchical Taxonomy of Psychopathology (HiTOP) is a quantitative nosological system that addresses shortcomings of traditional mental disorder diagnoses, including arbitrary boundaries between psychopathology and normality, frequent disorder co-occurrence, substantial heterogeneity within disorders, and diagnostic unreliability over time and across clinicians. This paper reviews evidence on the validity and utility of the internalizing and somatoform spectra of HiTOP, which together provide support for an emotional dysfunction superspectrum. These spectra are composed of homogeneous symptom and maladaptive trait dimensions currently subsumed within multiple diagnostic classes, including depressive, anxiety, trauma-related, eating, bipolar, and somatic symptom disorders, as well as sexual dysfunction and aspects of personality disorders. Dimensions falling within the emotional dysfunction superspectrum are broadly linked to individual differences in negative affect/neuroticism. Extensive evidence establishes that dimensions falling within the superspectrum share genetic diatheses, environmental risk factors, cognitive and affective difficulties, neural substrates and biomarkers, childhood temperamental antecedents, and treatment response. The structure of these validators mirrors the quantitative structure of the superspectrum, with some correlates more specific to internalizing or somatoform conditions, and others common to both, thereby underlining the hierarchical structure of the domain. Compared to traditional diagnoses, the internalizing and somatoform spectra demonstrated substantially improved utility: greater reliability, larger explanatory and predictive power, and greater clinical applicability. Validated measures are currently available to implement the HiTOP system in practice, which can make diagnostic classification more useful, both in research and in the clinic.

The influence of stimuli valence, extraversion, and emotion regulation on visual search within real-world scenes

Affective traits, including extraversion and emotion regulation, are important considerations in clinical psychology due to their associations with the occurrence of affective disorders. Previously, emotional real-world scenes have been shown to influence visual search. However, it is currently unknown whether extraversion and emotion regulation can influence visual search towards neutral targets embedded within real-world scenes, or whether these traits can impact the effect of emotional stimuli on visual search. An opportunity sample of healthy individuals had trait levels of extraversion and emotion regulation recorded before completing a visual search task. Participants more accurately identified search targets in neutral images compared to positive images, whilst response times were slower in negative images. Importantly, individuals with higher trait levels of expressive suppression displayed faster identification of search targets regardless of the emotional valence of the stimuli. Extraversion and cognitive reappraisal did not influence visual search. These findings add to our understanding regarding the influence of extraversion, cognitive reappraisal, and expressive suppression on our ability to allocate attention during visual search when viewing real-world scenes.

Decreases in State and Trait Anxiety Post-psilocybin: A Naturalistic, Observational Study Among Retreat Attendees

Anxiety disorders are the most common type of psychiatric disorders among Western countries. Evidence-based treatment modalities including pharmacological and cognitive-behavioral therapy result in deficient treatment responses. Historical and recent research suggests psychedelic drugs may be efficacious in alleviating anxiety-related symptoms among healthy and clinical populations. The main aim of the present study was investigation of the effects of psilocybin-containing truffles, when taken in a supportive group setting, on ratings of state and trait anxiety across self-reported healthy volunteers. Attendees of psilocybin ceremonies were asked to complete a test battery at three separate occasions: before the ceremony (baseline), the morning after, and 1 week after the ceremony. The test battery included questionnaires assessing state and trait anxiety (State-Trait Anxiety Inventory), mindfulness capacities (Five Facet Mindfulness Questionnaire), and personality (Big Five Inventory). Additionally, the psychedelic experience was quantified with the Persisting Effects Questionnaire and the Ego Dissolution Inventory. The total amount of psilocybin-containing truffles consumed by each participant was recorded, and a sample of the truffles was analyzed to determine psilocin concentrations. Fifty-two attendees (males = 25; females = 25; others = 2) completed parts of the baseline assessment, 46 (males = 21; females = 24; others = 1) completed assessments the morning after the ceremony, and 23 (males = 10; females = 13) completed assessments at the 1-week follow-up. Average psilocin consumption across individuals was 27.1 mg. The morning after the ceremony, we observed medium reductions in anxiety measures (both state and trait) compared to baseline ( d ¯ = 6.4; p < 0.001 and d ¯ = 6; p = 0.014, respectively), which persisted over a 1-week period post-ceremony ( d ¯ = 6.7; p = 0.001 and d ¯ = 8.6; p = 0.004, respectively). At 1 week post-ceremony, the non-judging facet of the mindfulness scale was increased ( d ¯ = 1.5; p = 0.03), while the personality trait neuroticism decreased ( d ¯ = 5.2; p = 0.005), when compared to baseline. Additionally, we found ratings of ego dissolution (mean: 59.7, SD: 28.3) and changes in neuroticism to be the strongest predictors of reductions in state and trait anxiety, respectively. In sum, results suggest rapid and persisting (up to 1 week) anxiolytic effects in individuals with sub-clinical anxiety symptoms, which are related to the acute experience of ego dissolution, as well as lasting changes in trait neuroticism. Results also add support to the feasibility and potential efficacy of group sessions with psychedelics. To understand whether these effects extend to wider populations suffering from heightened anxiety, and the mechanisms involved, further experimental research is needed.

Temperament and psychopathology in early childhood predict body dissatisfaction and eating disorder symptoms in adolescence

Eating disorders (ED) are highly impairing and dangerous conditions that typically onset in adolescence. However, very few prospective studies have examined early childhood risk factors for ED pathology. Given well-established links between temperament and psychopathology, examination of these factors could inform prevention efforts. The current multi-method, multi-informant prospective longitudinal study tested whether laboratory-observed and parent-reported temperament and psychiatric disorders at ages 3 and 6 (N = 609) predict body dissatisfaction at ages 12 and 15 and dimensional symptoms of EDs (anorexia nervosa [AN] and bulimia nervosa [BN]) at age 15 (n = 458) in a community sample. Results indicated that early childhood temperament (positive and negative emotionality, perceptual sensitivity, impulsivity, less shyness) and childhood psychopathology (anxiety, oppositional defiant, attention deficit/hyperactivity, and depressive disorders), predicted body dissatisfaction in adolescence. In addition, childhood perceptual sensitivity and oppositional defiant and depressive disorders predicted AN symptoms. Demographic characteristics (female sex, lower levels of fathers' education, and parental marital status) in childhood predicted body dissatisfaction and AN symptoms. No temperament or psychopathology variables predicted BN symptoms. This study is an important first step toward continuing to identify areas of focus for future research on early childhood risk factors for ED symptoms and body dissatisfaction.

Longitudinal network model of the co-development of temperament, executive functioning, and psychopathology symptoms in youth with and without ADHD

Attention-deficit hyperactivity disorder (ADHD) is a common, chronic, and impairing disorder, yet presentations of ADHD and clinical course are highly heterogeneous. Despite substantial research efforts, both (a) the secondary co-occurrence of ADHD and complicating additional clinical problems and (b) the developmental pathways leading toward or away from recovery through adolescence remain poorly understood. Resolving these requires accounting for transactional influences of a large number of features across development. Here, we applied a longitudinal cross-lagged panel network model to a multimodal, multilevel dataset in a well-characterized sample of 488 children (nADHD = 296) to test Research Domain Criteria initiative-inspired hypotheses about transdiagnostic risk. Network features included Diagnostic and Statistical Manual of Mental Disorders symptoms, trait-based ratings of emotional functioning (temperament), and performance-based measures of cognition. Results confirmed that ADHD symptom domains, temperamental irritability, and working memory are independent transdiagnostic risk factors for psychopathology based on their direct associations with other features across time. ADHD symptoms and working memory each had direct, independent associations with depression. Results also demonstrated tightly linked co-development of ADHD symptoms and temperamental irritability, consistent with the possibility that this type of anger dysregulation is a core feature that is co-expressed as part of the ADHD phenotype for some children.

Interactive influences of emotion and extraversion on visual attention

INTRODUCTION

Emotion has been shown to influence selective visual attention. However, studies in this field have revealed contradictory findings regarding the nature of this influence. One possible explanation for the variation in findings is that affective inter-individual differences impact both attention and emotion and may therefore moderate any influence of emotion on attention. The current work is a novel investigation of the effects of induced emotional states and the traits of extraversion and neuroticism on visual attention. This allowed a direct investigation of any impact of extraversion and neuroticism on the way in which emotion influences attention.

METHODS

Participants were induced into positive, neutral, and negative emotional states before completing a change detection flicker task in which they were required to locate a change to a real-world scene as quickly and accurately as possible.

RESULTS

Participants scoring higher in extraversion were more accurate but slower at detecting changes. Importantly, this was particularly evident when induced into a negative emotional state compared to a neutral emotional state. Neuroticism had no impact on attention.

CONCLUSIONS

The current study provides evidence that extraversion can moderate the influence of negative emotion upon visual attention and may help to explain some of the contradictory findings in this research area. When considered independently, increased trait levels of extraversion were associated with improved change detection. Individuals higher in extraversion appear better equipped to regulate negative emotion compared to individuals lower in extraversion, supporting research linking extraversion to affective reactivity and models of psychopathology.

Overlap between general factors of psychopathology and personality: They share associations with daily life functioning and communication style

Previous studies have shown that specific personality dimensions, -e.g., the Big Five-, consistently intercorrelate, such that they form a general factor of personality (GFP). It has been hypothesized that the GFP reflects social effectiveness. Similarly, in the clinical domain, overlap between various psychopathological symptoms has also been reported, leading to a general factor of Psychopathology, or p factor. The aim of this study was to test the overlap between the higher-order factors in personality and psychopathology, and how they relate to daily life functioning and communication style. We tested a sample of 165 outpatients of a psychological therapy institute, using a multi-source approach that included self-reports and other ratings. The outpatients’ self-reports of personality, general psychological problems, and interpersonal problems were available. Psychotherapists rated the outpatients’ functioning in daily life with the well-known Global Assessment of Functioning (GAF) scale. A spouse or friend also rated the impact of the patient’s communication/social behavior. Patients with lower GFP scores and higher scores on general psychopathology, displayed more distress and daily functioning deficits (i.e., lower GAF scores) and, in terms of communication styles, were also rated as being less dominant, less in control socially, and more submissive and aggressive. We proposed that part of the overlap between the general factors (GFP, psychopathology factors) may relate to a lower general life functioning and less social effectiveness.

Does maternal psychopathology bias reports of offspring symptoms? A study using moderated non-linear factor analysis

BACKGROUND

Mood-state biases in maternal reports of emotional and behavioral problems in their children have been a major concern for the field. However, few studies have addressed this issue from a measurement invariance perspective.

METHODS

Using data from baseline assessment of the Adolescent Brain Cognitive Development (ABCD) study (n = 8,507 mother-child dyads; youth aged 9-11 years), we examined how dimensions of maternal psychopathology, including internalizing problems, were associated with indices of bias in reports of their children's dimensions of internalizing, externalizing, neurodevelopmental, detachment, somatoform psychopathology using moderated non-linear factor analysis. Moderated non-linear factor analyses examined multiple potential biases in maternal reports of youth psychopathology.

RESULTS

Across analyses, we found very small magnitudes of associations between dimensions of maternal psychopathology and biases in reports of child emotional and behavioral problems.

CONCLUSIONS

Based on these results, we find little psychometric evidence for maternal psychopathology biasing reports of child behavior problems.

Adult separation anxiety: Personality characteristics of a neglected clinical syndrome

Over the past two decades, interest in the relationship between personality and psychopathology has resurged. However, the clinical problem of adult separation anxiety (ASA) has been largely excluded from this endeavor due to the age-of-onset criterion in older editions of the DSM that prohibited first-onset diagnoses in adulthood. This study tests relationships between ASA symptoms and higher- and lower-order personality traits in a community sample of 565 women. It accounts for systematic error by utilizing informant report, two personality inventories, and data from two time points over three years, and by adjusting for mood state. It also tests longitudinal ASA-personality models. Results indicate that ASA is robustly associated with negative emotionality and its facet of stress reaction, as well as with aggression, alienation, and absorption to somewhat lesser degrees. These relationships are not due to overlap with other traits (except in the case of alienation), or mood-state biases, and they are verified by informants. Moreover, negative temperament predicts greater levels of ASA three years later, adjusting for baseline ASA. Neither positive emotionality or temperament, nor positive emotionality's lower-order scales, were uniquely related to ASA in multitrait models, whereas relationships between ASA and disinhibition and constraint were inconsistent. These findings lay the groundwork for future research testing the mechanisms and causal links between these personality traits and ASA and may help clinicians anticipate traits that are associated with ASA in order to tailor treatments to patients' personalities.

COVID-19 and mental health of individuals with different personalities

Several studies have been devoted to establishing the effects of the COVID-19 pandemic on mental health across gender, age, and ethnicity. However, much less attention has been paid to the differential effect of COVID-19 according to different personalities. We do this using the UK Household Longitudinal Study (UKHLS), a large-scale panel survey representative of the UK population. The UKHLS allows us to assess the mental health of the same respondent before and during the COVID-19 period based on their "Big Five" personality traits and cognitive skills. We find that during the COVID-19 period, individuals who have more extravert and open personality traits report a higher mental health deterioration, while those scoring higher in agreeableness are less affected. The effect of openness is particularly strong: One more SD predicts up to 0.23 more symptoms of mental health deterioration in the 12-item General Health Questionnaire (GHQ-12) test during the COVID-19 period. In particular, for females, cognitive skills and openness are strong predictors of mental health deterioration, while for non-British White respondents, these predictors are extraversion and openness. Neuroticism strongly predicts worse mental health cross-sectionally, but it does not lead to significantly stronger deterioration during the pandemic. The study's results are robust to the inclusion of potential confounding variables such as changes in physical health, household income, and job status (like unemployed or furloughed).

Prenatal origins of temperament: Fetal cardiac development & infant surgency, negative affectivity, and regulation/orienting

Temperament, i.e. individual differences in reactivity and self-regulation, emerges early in infancy; might temperament originate during fetal development? Mixed findings and methodological issues in the literature examining this consideration limit our understanding of the continuity between these fetal indices and infant temperament. The primary aims of the current study were to improve on published studies by (a) using standardized and well-accepted fetal cardiac (actocardiograph) and infant temperament measures (the Infant Behavior Questionnaire-Revised; IBQ-R) (b) expanding fetal assessments to include coupling (the cross correlation of heart rate with movement), and (c) examining a diverse sample to determine if findings of associations between fetal neurobehavior and infant temperament generalize beyond cohorts that are demographically well-resourced and predominantly white. Building on theory and empirical findings, we hypothesized that (1) FHR would be positively associated with Surgency and Negative Affectivity, (2) FHRV would be positively associated with Surgency, and Regulation/Orienting and inversely associated with Negative Affectivity, and (3) fetal coupling would be positively associated with Regulation/Orienting and Surgency and inversely associated with Negative Affectivity. We collected 20 min of fetal data (m gestational age = 34.42 weeks) and mothers completed the IBQ-R (n = 90 women; 60 % non-Caucasian race; 63 % Latina ethnicity). We found that FHR was positively associated with Negative Affectivity but not associated with Surgency (or Regulation/Orienting). FHRV was inversely associated with Surgency but not associated with Negative Affectivity or Regulation/Orienting. Coupling was positively associated with Regulation/Orienting and Surgency but not associated with Negative Affectivity. Our findings, from a more diverse sample and with established measures, provide further evidence that individual differences in reactivity and regulation can be identified in the in-utero period and show theory-based continuity to specific infant temperament constructs.

Neurobiology and the Hierarchical Taxonomy of Psychopathology: progress toward ontogenetically informed and clinically useful nosology

The Hierarchical Taxonomy of Psychopathology (HiTOP) is an empirical structural model of psychological symptoms formulated to improve the reliability and validity of clinical assessment. Neurobiology can inform assessments of early risk and intervention strategies, and the HiTOP model has greater potential to interface with neurobiological measures than traditional categorical diagnoses given its enhanced reliability. However, one complication is that observed biological correlates of clinical symptoms can reflect various factors, ranging from dispositional risk to consequences of psychopathology. In this paper, we argue that the HiTOP model provides an optimized framework for conducting research on the biological correlates of psychopathology from an ontogenetic perspective that distinguishes among indicators of liability, current symptoms, and consequences of illness. Through this approach, neurobiological research can contribute more effectively to identifying individuals at high dispositional risk, indexing treatment-related gains, and monitoring the consequences of mental illness, consistent with the aims of the HiTOP framework.


Marital Satisfaction as a Moderator of Molecular Genetic Influences on Mental Health

The quality of one's romantic relationship is associated with mental health. Low levels of relationship quality may be a stressor that triggers a predisposition or diathesis to mental illness. Analyses were conducted to examine whether relationship quality moderated the association between polygenic risk scores (PRSs) for several mental health syndromes on phenotypic measures of those syndromes. Data were drawn from the Midlife in the United States (MIDUS) study of health and well-being. A subsample was genotyped, and PRSs were calculated. The PRS for anxiety was more strongly related to the anxiety phenotype when satisfaction was low than when satisfaction was high, providing evidence of a genetic susceptibility process between marital distress and anxiety. The expression of genetic influences on a phenotype in the presence of certain environmental stressors is complex and may depend on the specific phenotype and the methodology by which genetic influences are estimated.

On the efficacy of the unified protocol for transdiagnostic treatment of emotional disorders: A systematic review and meta-analysis

In recent years a large array of treatment protocols conceptualized as transdiagnostic have been developed with clinical and practical advantages compared to traditional single-disorder protocols. Within this panorama, the Transdiagnostic Unified Protocol (UP) of Emotional Disorders was developed aimed at treating the negative affective processes underlying several diagnostic categories, and accounting for the covariance of different emotional disorders. The UP has been found to efficiently target the roots of these disorders leading to a reduction in symptoms of co-occurring disorders. However, several questions have marginally addressed in the previous studies, and some UP features still remain unexplored. The present meta-analysis aims at evaluating whether the UP results to significant changes in anxiety and depression symptoms severity in children, adolescents, and adults. 19 RCTs and 13 uncontrolled pre-post trials comprising 2183 patients/clients met inclusion criteria for meta-analysis. Large to moderate combined overall effect size for both depression plus anxiety were detected in the uncontrolled pre-post studies (g = 0.756) and in RTCs studies (g = 0.452), respectively. Large effect size at pre-treatment to 3-6-month follow-up was observed for combined depression plus anxiety (g = 1.113). Subgroup analysis suggested that UP treatment does not differ across the anxiety and depression self-report measures. Moreover, UP intervention outperformed both passive and active control conditions to treat negative affective syndromes. Meta-regression confirmed the moderate effects of therapist level of experience, the sample characteristics, and the UP-protocol adaptations. The findings indicate that the manualized UP treatment has potential to contribute to improving mental health outcomes, particularly of anxiety and depression.
