Temperament traits and remission of depression: A naturalistic six-month longitudinal study

BackgroundThe aim of this naturalistic longitudinal study was to add evidence regarding the potential of Cloninger's temperament traits (novelty seeking, harm avoidance, reward dependence and persistence) for predicting the effect of pharmacological treatment on the rates of therapeutic response and remission. MethodsThe study was based on 200 outpatients with unipolar depressive disorders of different severity and course of illness, and extended up to 6 months of follow-up. Patients were assessed in their temperament with the Tridimensional Personality Questionnaire (TPQ) and their condition was classified (in course and severity) according to the International Classification of Diseases, Tenth revision (ICD-10) diagnostic criteria for research. Patients were blindly rated (concerning other predicting variables) on the improved Clinical Global Impression–Severity scale for depression (iCGI-S) at baseline, 6 weeks, 3 months and 6 months. Outcome measures at the last observation carried forward were therapeutic response (reduction of ≥50% in the last iCGI-S) and remission (last iCGI-S = 0), which were available for 187 patients. ResultsRemission was independently and directly associated with length of follow-up, and inversely with the baseline iCGI-S score and harm avoidance (patients in the high tertile had a 2.7 likelihood of non-remission in comparison with those in the low tertile); persistence was found to have a complex, V-shape relationship with remission. Within a sub-sample of more severe cases (n = 118), having higher harm avoidance scores, a more favorable outcome was associated with higher reward dependence and the non-smoking condition. LimitationsWith a naturalistic, non-experimental design, the sample may not be representative of the general population. ConclusionsTemperament traits may help predict outcome in patients treated for depression.

Presence of negative emotions in bronchial asthma / Presencia de emociones negativas en el asma bronquial

This paper investigates the presence of anxiety, anger and depression in a sample of patients with asthma from a hospital environment and a sample of people free of this respiratory disease. For this research, the Anxiety Situations and Responses Inventory (ASRA), the Spanish adaptation of the Stait-Trait Anger Expression Inventory (STAXI) and the Tri-dimensional Personality Questionnaire for Depression (TPQD) were used. Patients with respiratory disease scored significantly higher on negative emotions than people without asthma. The results will be discussed to consider the importance of taking emotions into account in order to handle the disease in a comprehensive manner

NGF gene polymorphisms are not associated with heroin dependence in a Taiwanese male population.

Heroin dependence (HD) is a chronic relapsing brain illness with substantial heritability. Nerve growth factor (NGF) is a crucial modulator in the neurodevelopment, and may be a key mediator of reward processes in HD. The purpose of this genetic study was to investigate whether NGF gene polymorphisms associate with the occurrence of HD and the specific personality traits of patients with HD. We selected a homogeneous Han Chinese male population to overcome possible confounding effects of population and gender. For the study, 272 HD patients and 141 controls completed the Tridimensional Personality Questionnaire to evaluate their personality traits. In addition, a further sample 303 HD patients and 204 controls was added (with totally 920 participants) for the gene association and genotype-phenotype interaction studies. Patients with HD had higher novelty seeking (NS) and harm avoidance (HA) scores than healthy subjects. Nonetheless, NGF gene polymorphisms did not associate with specific personality traits in HD patients and controls. There is no significant difference in NGF gene polymorphisms between patients with HD and controls. The NGF gene may neither contribute to the risk of development of HD, nor mediate the relationship between specific personality traits and HD in Han Chinese male population. Patients with HD had higher novelty seeking (NS) and harm avoidance (HA) scores than healthy subjects. However, none of the polymorphisms in the NGF gene affected the NS and HA scores in both patients and healthy subjects. (Am J Addict 2018;27:516-523).

Network analysis of specific psychopathology and psychiatric symptoms in patients with anorexia nervosa.

Network analysis is increasingly applied to psychiatric populations to understand relationships among symptoms. Network analysis was applied on 955 patients with anorexia nervosa (AN; 631 restricting-type [ANR] and 324 binge eating-/purging-type [ANBP]), assessed with Symptom Check-List 90 (SCL-90), Eating Disorder Inventory (EDI), and Tridimensional Personality Questionnaire. Depression, anxiety, interpersonal sensitivity (SCL-90), and ineffectiveness (EDI) had the highest centrality (strength from 1.19 to 1.35 in ANBP, and from 1.15 to 1.51 in ANR). Body mass index (BMI) had low centrality (0.14 ANBP and 0.41 ANR). Drive for thinness showed the strongest correlation with central nodes in ANBP (correlation around 0.44) and ANR (correlation range 0.38-0.47), and drive for thinness had higher centrality in ANR (1.15) than in ANBP (0.81), whereas body dissatisfaction in ANBP (0.73) than in ANR (0.61). In addition to ED-core symptoms, psychiatric comorbid symptoms should be the focus of specific treatments in patients with AN, independently from BMI.

A computer-based avatar task designed to assess behavioral inhibition extends to behavioral avoidance but not cognitive avoidance.

Avoidance is a common feature of post-traumatic stress disorder (PTSD) as well as anxiety and depressive disorders. Avoidance can be expressed behaviorally as well as cognitively. Most personality assessments for avoidance involve self-report inventories which are susceptible to biased responding. The avatar task (Myers et al., 2016a) was developed as an objective measure of behavioral inhibition (BI) which is defined as a tendency for avoidance of unfamiliar people and situations. The avatar task has been demonstrated to screen avoidant behaviors related to BI, PTSD, as well as harm avoidance (HA) as measured by the Tridimensional Personality Questionnaire (TPQ). In the current work, the avatar task was tested with cognitive as well as behavioral avoidance as measured by the cognitive-behavioral avoidance scale (CBAS; Ottenbreit & Dobson, 2004). The CBAS includes four subscales which measure behavioral social (BS) avoidance, behavioral non-social (BN) avoidance, cognitive social (CS) avoidance, and cognitive non-social (CN) avoidance. It was hypothesized that avatar scores would be significantly positively related to behavioral, but not cognitive, avoidance. In addition, it was also hypothesized that performance on the avatar task would be more related to social than non-social behavioral avoidance. Participants completed the avatar task, the HA scale of the TPQ and the CBAS. Pearson’s product moment correlations revealed that avatar scores were significantly related to CBAS total scores as well as BS and BN scores, but not CS and CN scores. In addition, BS has a stronger relationship with avatar scores than BN avoidance which fits with the social aspects of the scenarios in the avatar task. A median split of the avatar scores produced a significant difference in scores on the behavioral but not the cognitive subscales. Overall, the current results supported the idea that the avatar task is measuring behavioral avoidance, specifically in social situations, rather than cognitive avoidance. Future work could adapt the avatar task to include scenarios similar to the cognitive items on the CBAS to create an objective measure of cognitive avoidance which may be relevant in measuring avoidance in depression and behavioral avoidance associated with PTSD as well as anxiety disorders.

Food and nutrient intakes by temperament traits: findings in the Helsinki Birth Cohort Study.

Previous studies have shown that the temperament traits are related to risk factors for chronic diseases, which could be partly explained by lifestyle habits. However, little is known whether temperament traits associate with diet. The aim of this study was to examine the cross-sectional associations between temperament traits and the whole diet. We studied 1668 men and women, aged 56-70, from the Helsinki Birth Cohort Study. Temperament was measured using the Tridimensional Personality Questionnaire. Information on diet was collected by a validated 128-item food frequency questionnaire. The associations of temperament traits; novelty seeking (NS), harm avoidance (HA), reward dependence (RD), and persistence (P), with diet were tested by linear regression analysis. After adjustment for potential confounders, greater HA was related to poorer diet quality, including lower consumption of vegetables, fruits, fish and several vitamins. RD was associated with healthier diet quality, including higher consumption of vegetables and intake of vitamin E and lower intake of alcohol. NS was significantly related to higher intake of fish, fat and alcohol and lower consumption of cereals, milk products and carbohydrates. No significant associations between P and intake of foods and nutrients were observed. Our results suggest that there is an association between temperament traits and diet. Especially greater HA seems to associate with poorer diet quality and greater RD with healthier diet quality.

Network analysis of specific psychopathology and psychiatric symptoms in patients with eating disorders.

Network analysis of psychiatric symptoms describes reciprocal relationships of individual symptoms, beyond categorical diagnoses. Those with eating disorders (EDs) frequently have complex patterns of comorbid symptoms and the transdiagnostic theory includes shared common core features across diagnoses. We aim to test whether general psychiatric symptoms comprise components of these transdiagnostic features. Network analysis was applied on 2068 patients with EDs (955 anorexia nervosa [AN], 813 bulimia nervosa [BN], and 300 binge-eating disorder [BED]). All patients underwent clinical interviews and some self-reported questionnaires, such as the Symptom Check-List 90 (SCL-90) to measure psychiatric symptoms, the Eating Disorder Inventory (EDI) to measure ED-specific symptoms, and the Tridimensional Personality Questionnaire (TPQ) for personality traits. Across EDs and within each ED, SCL-90 scores of depression, anxiety and interpersonal sensitivity, EDI ineffectiveness, interoceptive awareness, interpersonal distrust, and drive for thinness had high centrality. Notably, body mass index (BMI) and EDI bulimia played a central role when considering the whole group, whereas they did not in individual EDs. The shared centrality of identified nodes in both individual and merged groups supported the transdiagnostic theory of EDs (diagnoses share core ED features), with a central role of BMI. Moreover, the most central nodes were general psychiatric symptoms, interpersonal domain, and self-efficacy. These findings suggest that-in addition to ED-core symptoms and BMI-depressive and anxiety symptoms, interpersonal sensitivity and ineffectiveness may be important targets to provide effective treatments across AN, BN, and BED.

Salivary Alpha-Amylase and Behavior Reaction in Acute Stress and the Impact of Tridimensional Personality.

Understanding individual differences of these indexes in response to stress is important for developing effective interventions. The Tridimensional Personality Questionnaire (TPQ), which has three dimensions, may reflect such individual differences. Meanwhile, there is increasing interest in the relationship between mental stress and non-invasive markers. We examined whether these three dimensions were associated with cognitive behavior tests and the related sAA responses. All subjects were divided into different groups based on the scores of the TPQ measuring temperament dimensions. Patterns of Stroop combined with mental arithmetic stress tests were presented, and the sAA responses were recorded as the index of stress responses, and compared between groups. The sAA levels in the post stress test and the recovery period of the high reward-dependence (RD) group were significantly greater than in the low-RD group. The number of trials of Stroop in the high novelty-seeking (NS) group was significantly greater than in the low-NS group. Individual differences in TPQ personality traits may be associated with different patterns of stress responses.

Lack of association between NeuroD1/D6 gene polymorphism and heroin dependence in Han-chinese male population

Objectives: Heroin dependence (HD) is a chronic brain disease with genetic contribution. NeuroD1/D6 are neurogenic differentiation factors that play a role in development and differentiation of the brain. In this study, we intended to investigate the association of NeuroD1/D6 gene polymorphism and the occurrence of HD, and the role of this genetic variability in specific personality traits of HD patients. Materials and Methods: A total of 694 individuals were recruited in this study (313 HD patients and 381 normal controls). Patients with HD were further classified into four clinical subgroups to reduce heterogeneity. Genetic variants of selected single-nucleotide polymorphisms in NeuroD1 (rs1801262, rs16867467, and rs2583016) and NeuroD6 (rs2233404) were genotyped. We used the Chinese version of tridimensional personality questionnaire to assess specific personality traits in subjects. Results: For allele and genotype frequency analysis, we found a weak association between NeuroD1 rs16867467 and patients with HD (P < 0.05). Nonetheless, the association findings could not remain significant after Bonferroni's correction. For specific personality traits, NS score was negatively correlated with age in both study groups (P < 0.05); however, the NeuroD SNPs were not associated with the novelty-seeking/harm avoidance scores in patients with HD. Conclusions: Our study suggests that NeuroD1/D6 gene polymorphism may neither be associated with the occurrence of HD nor did these polymorphisms influence the personality traits in patients with HD.

Beyond Behavioral Inhibition: A Computer Avatar Task Designed to Assess Behavioral Inhibition Extends to Harm Avoidance.

Personality factors such as behavioral inhibition (BI), a temperamental tendency for avoidance in the face of unfamiliar situations, have been identified as risk factors for anxiety disorders. Personality factors are generally identified through self-report inventories. However, this tendency to avoid may affect the accuracy of these self-report inventories. Previously, a computer based task was developed in which the participant guides an on-screen “avatar” through a series of onscreen events; performance on the task could accurately predict participants’ BI, measured by a standard paper and pencil questionnaire (Adult Measure of Behavioral Inhibition, or AMBI). Here, we sought to replicate this finding as well as compare performance on the avatar task to another measure related to BI, the harm avoidance (HA) scale of the Tridimensional Personality Questionnaire (TPQ). The TPQ includes HA scales as well as scales assessing reward dependence (RD), novelty seeking (NS) and persistence. One hundred and one undergraduates voluntarily completed the avatar task and the paper and pencil inventories in a counter-balanced order. Scores on the avatar task were strongly correlated with BI assessed via the AMBI questionnaire, which replicates prior findings. Females exhibited higher HA scores than males, but did not differ on scores on the avatar task. There was a strong positive relationship between scores on the avatar task and HA scores. One aspect of HA, fear of uncertainty was found to moderately mediate the relationship between AMBI scores and avatar scores. NS had a strong negative relationship with scores on the avatar task, but there was no significant relationship between RD and scores on the avatar task. These findings indicate the effectiveness of the avatar task as a behavioral alternative to self-report measures to assess avoidance. In addition, the use of computer based behavioral tasks are a viable alternative to paper and pencil self-report inventories, particularly when assessing anxiety and avoidance.

High novelty seeking as a predictor of antisocial behaviour in early adulthood.

This study aimed to examine the association between novelty seeking (NS) and antisocial behaviours (age 18-35). A New Zealand general population birth cohort was studied from 1977 to 2012. Sample sizes ranged from n=962 (age 35) to n=1025 (age 18). NS was measured at age 16 using the Tridimensional Personality Questionnaire. Perpetration of antisocial behaviours was ascertained by self-report at ages 18, 21, 25, 30 and 35. Generalized estimating equation models investigated the association between NS and antisocial behaviours net of individual factors and correlates of NS before age 16 and alcohol and substance use disorders at age 18-35. Higher NS scores were associated with a higher unadjusted incidence of all forms of antisocial behaviour. Assault, theft, property damage and dishonesty offending remained associated with NS after adjustment for individual factors and correlates of NS before age 16. After further adjustment for alcohol and substance use disorders, NS was not associated with any antisocial behaviour outcomes, suggesting those disorders mediate the association between NS and antisocial behaviours. Alcohol and substance use disorders mediate the association between NS and antisocial behaviours in early adulthood. NS may be a useful endophenotype for investigating the causation of externalizing behaviours. Copyright © 2017 John Wiley & Sons, Ltd.

The association between harm avoidance personality traits and self-reported concussion history in South African rugby union players.

Personality traits have been proposed to affect the risk of sports concussion, but evidence is limited. Cloninger's Tridimensional Personality Questionnaire (TPQ) measures novelty seeking, harm avoidance (HA), and reward dependence traits. The aim of this study was to investigate the relationship between TPQ scores and concussion history in rugby union players. Cross-sectional study. Rugby players from high schools, senior amateur clubs, and professional teams provided a self-reported concussion history and completed the TPQ. Participants reporting no previous concussions formed the control group, while participants reporting concussion formed the case group. A one-way analysis of covariance, with age as a covariate, was used to examine the differences in TPQ scores between groups. Of the 309 participants, 54% reported a minimum of one concussion (junior: 47%; amateur: 52%; professional: 72%). HA scores were significantly higher in junior players without a history of concussion compared to cases (p=0.006). Specifically, the junior control group had higher "anticipatory worry" (p=0.009) and "fear of uncertainty" (p=0.008). In contrast, the professional control group had lower HA scores than cases (p=0.009), while the amateur cohort displayed no differences between control and case groups. This study identified a novel association between HA and concussion in rugby players, adding evidence to the role of personality in a multifactorial risk-model of concussion. The findings suggest that lower HA may lead to increased dangerous play in youth rugby, influencing concussion susceptibility. Contrasting associations in the professional cohort suggest further research is required to understand the role of personality in concussion.

The association between COMT rs4680 and 5-HTTLPR genotypes and concussion history in South African rugby union players

ABSTRACTThe objective was to investigate the relationship between Catechol-O-methyltransferase (COMT) rs4680 and serotonin-transporter-linked polymorphic region (5-HTTLPR) genotypes with concussion history and personality traits. Rugby players (“all levels”: n = 303), from high schools (“junior”, n = 137), senior amateur, and professional teams (“senior”, n = 166), completed a self-reported concussion history questionnaire, Cloninger’s Tridimensional Personality Questionnaire, and donated a DNA sample. Participants were allocated into control (non-concussed, n = 140), case (all) (previous suspected or diagnosed concussions, n = 163), or case (diagnosed only) (previous diagnosed concussion, n = 140) groups. COMT rs4680 Val/Val genotypes were over-represented in controls in all levels (P = 0.013, OR:2.00, 95% CI:1.15–3.57) and in juniors (P = 0.003, OR:3.57, 95% CI:1.45–9.09). Junior Val/Val participants displayed increased “anticipatory worry” (P = 0.023). The 5-HTTLPR low expressing group was under-represented in controls when all levels were considered (P = 0.032; OR:2.02, 95% CI:1.05–3.90) and in juniors (P = 0.021; OR:3.36, 95% CI:1.16–9.72). Junior 5-HTTLPR low and intermediate expressing groups displayed decreased “harm avoidance” (P = 0.009), “anticipatory worry” (P = 0.041), and “fear of uncertainty” (P < 0.001). This study provides preliminary indications that personality associated genetic variants can influence concussion in rugby.

Relationship between personality traits and clinical nurse competence in third-A level hospitals

Objective To verify the relationship between personality traits and clinical nurse competence in five third-A level hospitals in Shenyang. Methods A total of 1 559 clinical nurses from five tertiary-level hospitals in Shenyang were recruited into this study. Two self-report questionnaires, the Nurse Competence Scale (NCS) and the Tridimensional Personality Questionnaire (TPQ), were used to collect data. Results The average score of NCS was 71.97±13.25.Nursing competence increased with the increase of working years (β= 0.272, P< 0.01) and RD (β= 0.134, P< 0.01). Practicing nurses with the lower HA appear to have a higher level of competence (β=-0.117, P< 0.01). Conclusions The overall level of nurses′ competencies good in third-A level hospitals in Shenyang. The predicting factors of nursing competence are work experience, HA and RD. More psychological courses should be provided in fundamental nursing education and continuing nursing education for helping nurses shape their good personality traits.

The role of novelty seeking as a predictor of substance use disorder outcomes in early adulthood.

There has been a great deal of evidence showing that high novelty seeking (NS) is a risk factor for the development of substance use disorders (SUDs). However, the possible causal role of NS in SUDs is unconfirmed. The aim of this study was to examine the associations between NS at age 16 and SUDs from ages 18 to 35years, net of a series of covariate factors. Longitudinal study of a birth cohort. Christchurch, New Zealand. General community sample with sample sizes ranging from n=1011 (age 21) to n=962 (age 35). The Composite International Diagnostic Interview was used to derive DSM-IV diagnoses of alcohol, nicotine, cannabis and other illicit SUDs at four time intervals from ages 18 to 35. NS was measured at age 16 using the Tridimensional Personality Questionnaire. An increase in NS was associated with increases in the prevalence of all four SUDs at age 18-35. Following adjustment for a broad range of covariate factors, estimated effect sizes (odds ratios) were reducing in magnitude, but remained moderate to large. Adjusted odds ratios of SUDs for the highest NS quartile compared to with the lowest were 2.0 [95% confidence interval (CI)=1.5, 2.7] for alcohol; 1.8 (95% CI=1.3, 2.7) for nicotine; 3.6 (95% CI=2.4, 5.6) for cannabis and 5.1 (95% CI=2.9, 9.2) for other illicit substances. The association between high novelty seeking and substance use disorders is not explained by common underlying individual factors and environmental exposures. This is consistent with the view that novelty seeking may play a causal role in the development of substance use disorders.

Temperament traits in suicidal and non-suicidal mood disorder patients in Taiwan

Suicide is a major social and clinical problem in Asia. Although studies have suggested that personality traits are possible risk factors for suicide, no study has been conducted among Chinese to compare the temperament traits of suicidal and non-suicidal mood disorder patients with those of healthy controls. This study compared temperament traits of two patient groups, those with a mood disorder who have attempted suicide (n=204), and those with a mood disorder who have not attempted suicide (n=160), and compared the traits of these patients to those of healthy controls (n=178), assessed by Cloninger's Tridimensional Personality Questionnaire and the Brown-Goodwin Aggression Inventory. Patients with suicidal attempts had significantly higher novelty seeking and aggression scores than healthy controls and patients without suicidal attempts. Two groups of patients with mood disorder had significantly higher harm avoidance scores than the healthy controls. However, patients with suicidal attempts did not have higher harm avoidance scores than patients without suicidal attempts. This study confirms findings that harm avoidance and mood disorder are related, and extends them by suggesting that those with a mood disorder and suicide attempts have higher novelty seeking and lifetime aggression scores than those without suicidal attempt, either patients or healthy controls.

Overweight/obese patient referrals to plastic surgery: Temperamental and personality traits

IntroductionCorrelations between psychiatric disorders and overweight/obesity are reported in the literature. The study aimed at detecting correlations between psychiatric disorders, temperamental traits and body image perception in overweight and obese patients who seek surgical lipostructuring treatments.Methods28 overweight/obese patients (age 18–60 yrs, BMI 25 to 34.9 at recruitment) were enrolled in the period March 2008–June 2011 between those referring to the outpatient service for Obesity-related lipodystrophisms of the Institute of Plastic Surgery. Presence of psychiatric disorders, temperamental traits and body image perception were evaluated, and compared to a control group (n = 25) from general population sharing clinical/demographic features. Psychiatric evaluation was based on acquisition of clinical history, Mini-International Neuropsychiatric Interview, Beck Depression Inventory, Yale Brown Scale (YBOCS), Paykel Life Events Scale, NEO Five Factory Inventory, Tridimensional Personality Questionnaire (TPQ), Body Shape Questionnaire (BSQ).ResultsThe patients group presented higher scoring in lifetime depression and BSQ with moderate/mild concern with body shapes. With regard to personality traits, TPQ revealed higher score in subscale RD4 (dependence/independence) in the patients, while controls scored higher in “openness to experience” NEO-FFI sub-scale. At YBOCS obese patients presented higher prevalence of obsessive characters.ConclusionThe affective sphere is a relevant feature in obese patients, but also obsessive traits, as negative body shape perception and temperamental and personality characteristics appear to be involved in leading patients to seek surgical consultation. These aspects are implicated in medical/surgical outcome and compliance to treatments.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Self-transcendence and excessive TV commercial viewing in senior pupils

Self-transcendence is an important component of mental health and emotional well-being, and associates with everyday stress. The aim of this study was to reveal the relationships between excessive TV commercial viewing and self-transcendence. Forty-two healthy senior pupils aged 14–17 years participated in the study. We used the temperament and character inventory by cloninger, cloninger tridimensional personality questionnaire, the school anxiety test by Philips, Maddi Hardiness survey, and the emotional intelligence self-evaluation by Hall. We found that excessive TV commercial viewing has been linked to self-transcendence, which directly correlates with empathy and school anxiety. There was an inverse correlation between self-transcendence and self-directedness. We also found interrelations between self-transcendence and reward dependence, mediated by the noradrenergic brain system. We argue that the propensity for watching TV commercials and self-transcendence may determine the activity of monoaminergic brain systems along with the constitutional traits and personality characteristics.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Subsyndromal psychosomatic concepts and personality traits in community adults

ObjectiveTo investigate the prevalence of features of the Diagnostic Criteria for Psychosomatic Research (DCPR) in the Taiwanese community and to explore their relationships with psychological states and personality traits. MethodThe participants were 153 individuals without a DSM-5 psychiatric diagnosis who were grouped according to whether they had a DCPR diagnosis (at least one DCPR diagnosis, DCPR(+): n=66; no DCPR diagnosis, DCPR(−): n=87). The groups were compared with respect to psychological states (measured with Patient Health Questionnaire-15 [PHQ-15], Health Anxiety Questionnaire [HAQ], Beck Depression Inventory-II [BDI-II], Beck Anxiety Inventory [BAI)]) and personality (measured with Tridimensional Personality Questionnaire). Multiple logistic and linear regressions were used to examine associations among demographic, personality, DCPR, and psychological states. ResultsThe DCPR(+) group had higher BDI-II, BAI, PHQ-15 and HAQ scores than the DCPR(−) group and also had a higher anticipatory worry. The most common DCPR diagnoses were health anxiety (42.42%) and alexithymia (37.88%). Anticipatory worry was the variable most closely associated with all the DCPR diagnoses. Health anxiety was related to anticipatory worry and age, whereas alexithymia was associated with dependence and fatiguability. PHQ-15, HAQ, and BDI-II scores were related to health anxiety but not alexithymia. ConclusionDCPR has clinical utility in the community samples without DSM-5 diagnoses. DCPR may be a valid mediator between psychological trait and state.

Reward Dependence and Harm Avoidance among Patients with Binge-Purge Type Eating Disorders.

The Cloninger's Psychobiological Model of Temperament and Character includes temperamental dimensions such as reward dependence (RD) and harm avoidance (HA). Studies of RD differentiate between sensitivity to reward (SR) versus to punishment (SP). We investigated the interrelationship between HA and RD in acutely ill patients with binge/purge (B/P) type eating disorders (EDs) and following symptomatic stabilization. Fifty patients with B/P EDs were assessed at admission to inpatient treatment, 36 of whom were reassessed at discharge. Thirty-six controls were similarly assessed. Participants completed Tridimensional Personality Questionnaire (TPQ), Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ), and took the Gambling Task. Patients with B/P EDs had higher TPQ-RD and lower TPQ-HA accompanied by lower SPSRQ-SR and SPSRQ-SP. SPSRQ-SP correlated positively and negatively with TPQ-HA and TPQ-RD, respectively. Combination of lower TPQ-HA, lower SPSRQ-SP, and greater risk-taking inclination may maintain disordered eating in patients with B/P EDs.
