Alexithymia and Suicide Risk in Psychiatric Disorders: A Mini-Review

Different structural connectivity patterns in the subregions of the thalamus, hippocampus, and cingulate cortex between schizophrenia and psychotic bipolar disorder

OBJECTIVE

Schizophrenia (SCZ) and psychotic bipolar disorder (PBD) are two major psychotic disorders with similar symptoms and tight associations on the psychopathological level, posing a clinical challenge for their differentiation. This study aimed to investigate and compare the structural connectivity patterns of the limbic system between SCZ and PBD, and to identify specific regional disruptions associated with psychiatric symptoms.

METHODS

Using sMRI data from 146 SCZ, 160 PBD, and 145 healthy control (HC) participants, we employed a data-driven approach to segment the hippocampus, thalamus, hypothalamus, amygdala, and cingulate cortex into subregions. We then investigated the structural connectivity patterns between these subregions at the global and nodal levels. Additionally, we assessed psychotic symptoms by utilizing the subscales of the Brief Psychiatric Rating Scale (BPRS) to examine correlations between symptom severity and network metrics between groups.

RESULTS

Patients with SCZ and PBD had decreased global efficiency (Eglob) (SCZ: adjusted P<0.001; PBD: adjusted P = 0.003), local efficiency (Eloc) (SCZ and PBD: adjusted P<0.001), and clustering coefficient (Cp) (SCZ and PBD: adjusted P<0.001), and increased path length (Lp) (SCZ: adjusted P<0.001; PBD: adjusted P = 0.004) compared to HC. Patients with SCZ showed more pronounced decreases in Eglob (adjusted P<0.001), Eloc (adjusted P<0.001), and Cp (adjusted P = 0.029), and increased Lp (adjusted P = 0.024) compared to patients with PBD. The most notable structural disruptions were observed in the hippocampus and thalamus, which correlated with different psychotic symptoms, respectively.

CONCLUSION

This study provides evidence of distinct structural connectivity disruptions in the limbic system of patients with SCZ and PBD. These findings might contribute to our understanding of the neuropathological basis for distinguishing SCZ and PBD.

The role of alexithymia in suicide ideation among Taiwanese army military personnel: A serial mediation model investigating the effects of perceived stress and depression

Maintaining the good mental health of Taiwanese military personnel is crucial, especially in light of incidents such as the Taiwan Strait crisis. Suicide is a leading cause of death among military personnel and alexithymia is a significant risk factor for suicidal ideation. However, the mechanisms linking alexithymia and suicidal ideation in this psychologically burdened population remain poorly understood. In total, 863 voluntary army military personnel from Taiwanese reserve brigades and combined-arms brigades were enroled between May 2020 and February 2021. Structured questionnaires about alexithymia, perceived stress, depression, suicidal ideation, and background characteristics were used. Mediation analyses were conducted to examine the serial mediation roles of perceived stress and depression in the relationship between alexithymia and suicidal ideation. Significant positive correlations were observed between alexithymia, perceived stress, depression, and suicidal ideation in bivariate analyses. Serial mediation analyses revealed that alexithymia significantly predicted higher levels of perceived stress, subsequently leading to depressive symptoms, which were associated with suicidal ideation. Depression served as a significant mediator between alexithymia and suicidal ideation. The strongest mediating effect (71.4%) was observed in the pathway from alexithymia through perceived stress and depression to suicidal ideation. Limitations included the utilization of cross-sectional data and a reliance on retrospective self-report measures. Perceived stress and depression were identified as serial mediators in the association between alexithymia and suicidal ideation. Clinically, it is crucial to prioritise interventions that target emotional regulation skills and assess the presence of alexithymia to effectively reduce suicidal ideation in military personnel.

An fMRI study on alexithymia and affective state recognition in the Reading the Mind in the Eyes Test

Recognizing others' affective states is essential for successful social interactions. Alexithymia, characterized by difficulties in identifying and describing one's own emotions, has been linked to deficits in recognizing emotions and mental states in others. To investigate how neural correlates of affective state recognition are affected by different facets of alexithymia, we conducted a functional magnetic resonance imaging study with 53 healthy participants (aged 19-36 years, 51% female) using the Reading the Mind in the Eyes Test (RMET) and three different measures of alexithymia [Toronto Structured Interview for Alexithymia (TSIA), Toronto Alexithymia Scale (TAS-20), and Bermond-Vorst Alexithymia Questionnaire]. In addition, we examined brain activity during the RMET and replicated previous findings with task-related brain activation in the inferior frontal and temporal gyri, as well as the insula. No association was found between alexithymia and behavioral performance in the RMET, possibly due to the low number of participants with high alexithymia levels. Region of interest based analyses revealed no associations between alexithymia and amygdala or insula activity during the RMET. At the whole-brain level, both a composite alexithymia score and the unique variance of the alexithymia interview (TSIA) were associated with greater activity in visual processing areas during the RMET. This may indicate that affective state recognition performance in alexithymia relies on a higher compensatory activation in visual areas.

The mediating effects of school bullying victimization in the relationship between childhood trauma and NSSI among adolescents with mood disorders

BACKGROUND

Nonsuicidal self-injury (NSSI) is a serious problem in the adolescent population worldwide. Childhood trauma and bullying have been identified as risk factors for NSSI. We explored the relationships among Childhood trauma, Bullying victimization and the severity of NSSI behaviours, and test the effect of Bullying victimization in mediating the association between Childhood trauma and the NSSI behaviours.

METHODS

A total of 123 adolescents were recruited. They were diagnosed with depression or depressive episodes of bipolar disorder and had experienced NSSI in the last year. They were assessed using the Chinese version of the Childhood Trauma Questionnaire (CTQ-C), the Revised Olweus Bullying Victimization Questionnaire (OBVQ-R), and the Adolescent Self-Harm Questionnaire (ASHQ).

RESULTS

Females presented a significantly greater prevalence of sexual abuse and relationship bullying than boys. Individuals in the younger age group (10-14 years) presented a greater incidence of emotional neglect, verbal bullying, relationship bullying, and total bullying, and their NSSI score was also higher than that of those in the older age group (15-19 years). Only children show a greater prevalence of sexual abuse than nononly children. Single-parent families scored higher on emotional abuse, emotional neglect, physical neglect and physical bullying than two-parent families. There was a significant positive correlation between each dimension of childhood trauma and all the dimensions of bullying, between childhood trauma and NSSI, and between bullying and NSSI. Childhood trauma can not only directly affect the severity of NSSI but also indirectly aggravate the severity of NSSI through bullying victimization. The mediating effects of bullying victimization on emotional abuse, physical abuse, emotional neglect and physical neglect were 14%, 21%, 20%, 13% and 20%, respectively.

CONCLUSION

There was a significant positive correlation between childhood trauma and bullying, between childhood trauma and NSSI, and between bullying and NSSI. Childhood trauma can not only directly affect the severity of NSSI but also indirectly aggravate the severity of NSSI through bullying victimization. Bullying victimization played the partial mediating effects between Childhood trauma and NSSI.

The role of Theory of Mind in the transition towards suicidal attempts in youth NSSI: an exploratory pilot study

Non-suicidal self-injury (NSSI) can both precede and co-occur with suicidal attempts (SA). Underlying mechanisms/factors leading to the transition to SA in NSSI youths have been proposed (including the role of social cognition), despite they should be yet confirmed. Therefore, the study aims at exploring the role of the Theory of Mind in the differentiation of a sample of NSSI youngsters (aged 15-24) according to the presence of SA. We divided the sample into 4 groups using the Deliberate Self Harm Inventory (DSHI) and Columbia Suicide Severity Rating Scale (C-SSRS): control group (notNSSInotSA), NSSI without SA (NSSInotSA), NSSI with SA (NSSIplusSA), and SA without NSSI (SAonly). NSSIplusSA patients displayed higher Reading the Mind in the Eyes Test (RMET) scores (indicative of ToM abilities) than both the NSSInotSA (p=0.0016) and SAonly groups (p=0.0198), while SAonly patients showed lower RMET scores compared to the control group (p=0.0214). Multiple regression models used to differentiate NSSInotSA and NSSIplusSA found a significant association between RMET and LOSCS-CSC (Level Of Self-Criticism Scale-Comparative Self-Criticism) (pC=0.0802, pD=0.0016, pG=0.0053). Our findings supported the hypothesis that a hypertrophic affective ToM may possibly be associated with the occurrence of SA in youth NSSI. Further larger and longitudinal studies should confirm these preliminary findings, by exploring all social cognition dimensions.

Biobehavioral approach to distinguishing panic symptoms from medical illness

Panic disorder is a common psychiatric diagnosis characterized by acute, distressing somatic symptoms that mimic medically-relevant symptoms. As a result, individuals with panic disorder overutilize personal and healthcare resources in an attempt to diagnose and treat physical symptoms that are often medically benign. A biobehavioral perspective on these symptoms is needed that integrates psychological and medical knowledge to avoid costly treatments and prolonged suffering. This narrative review examines six common somatic symptoms of panic attacks (non-cardiac chest pain, palpitations, dyspnea, dizziness, abdominal distress, and paresthesia), identified in the literature as the most severe, prevalent, or critical for differential diagnosis in somatic illness, including long COVID. We review somatic illnesses that are commonly comorbid or produce panic-like symptoms, their relevant risk factors, characteristics that assist in distinguishing them from panic, and treatment approaches that are typical for these conditions. Additionally, this review discusses key factors, including cultural considerations, to assist healthcare professionals in differentiating benign from medically relevant symptoms in panic sufferers.

The mediating effect of internet addiction and the moderating effect of physical activity on the relationship between alexithymia and depression

There is a certain relationship between alexithymia and depression, but further investigation is needed to explore their underlying mechanisms. The aims of this study was to explore the mediating role of internet addiction between alexithymia and depression and the moderating role of physical activity. A total of 594 valid responses were included in the analysis, with a mean age of 18.72 years (SD = 1.09). The sample comprised 250 males (42.09%) and 344 females (57.91%). These responses were utilized for descriptive analysis, correlation analysis, regression analysis, and the development of mediation and moderation models. Alexithymia showed positive correlations with depression and internet addiction, and physical activity was negatively correlated with internet addiction and depression. Internet addiction partially mediated the relationship between alexithymia and depression, while physical activity weakened the association between internet addiction and depression, acting as a moderator. Our findings suggest that excessive Internet engagement may mediate the relationship between alexithymia and depression as an emotional regulatory coping strategy, and that physical activity attenuates the predictive effect of Internet addiction on depression.

Beyond sleepless nights: Unraveling the complexity of alexithymia and suicide risk among university students

BACKGROUND

There is a solid relationship between alexithymia and suicide risk. Nonetheless, the specific impact of alexithymia's distinct subscales on suicide risk has received the attention it deserves. This article presents a comprehensive exploration of suicide risk among university students, focusing on the interconnections among alexithymia, insomnia, and suicidal behavior. Three components of alexithymia including difficulties in describing emotions or feelings (DDF), difficulties in identifying emotions or feelings (DIF), and the externally oriented thinking were considered.

METHODS

The study involved 208 participants from a Persian university sample, examining the significance of incorporating both alexithymia and insomnia in suicide risk assessment and intervention planning. Insomnia was positioned as a pivotal mediator. A secure electronic link in the Telegram application was employed to collect the data. Both linear and nonlinear prediction models were used to explore potential associations among alexithymia, insomnia, and suicide risk.

RESULTS

The study revealed substantial positive correlations between alexithymia and suicide risk, as well as between insomnia and suicide risk. Additionally, specific components of alexithymia exhibited noteworthy links to suicide risk. The inclusion of insomnia scores in suicide risk predictions is critical, as it greatly enhances the precision of risk assessments and facilitates the design of targeted and effective therapeutic interventions. The association between alexithymia and suicide risk showed a significant relationship (r = .29, p < .01). Moreover, a significant correlation was observed between alexithymia and insomnia (r = .32, p < .01). Additionally, insomnia exhibited a significant positive correlation with suicide (r = .35, p < .01). Interestingly, DDF and DIF showed positive correlations with suicide (r = .28, p < .01; r = .33, p < .01).

CONCLUSION

The findings carry profound implications for suicide prevention efforts, providing valuable insights to safeguard the well-being and resilience of university students facing suicide risk challenges.

Alexithymia, Burnout, and Hopelessness in a Large Sample of Healthcare Workers during the Third Wave of COVID-19 in Italy

In the present study, we aimed to assess the frequency of and the relationships between alexithymia, burnout, and hopelessness in a large sample of healthcare workers (HCWs) during the third wave of COVID-19 in Italy. Alexithymia was evaluated by the Italian version of the 20-item Toronto Alexithymia Scale (TAS-20) and its subscales Difficulty in Identifying Feelings (DIF), Difficulty in Describing Feelings (DDF), and Externally Oriented Thinking (EOT), burnout was measured with the scales emotional exhaustion (EE), depersonalisation (DP), and personal accomplishment (PA) of the Maslach Burnout Test (MBI), hopelessness was measured using the Beck Hopelessness Scale (BHS), and irritability (IRR), depression (DEP), and anxiety (ANX) were evaluated with the Italian version of the Irritability' Depression' Anxiety Scale (IDA). This cross-sectional study recruited a sample of 1445 HCWs from a large urban healthcare facility in Italy from 1 May to 31 June 2021. The comparison between individuals that were positive (n = 214, 14.8%) or not for alexithymia (n = 1231, 85.2%), controlling for age, gender, and working seniority, revealed that positive subjects showed higher scores on BHS, EE, DP IRR, DEP, ANX, DIF, DDF, and EOT and lower on PA than the not positive ones (p < 0.001). In the linear regression model, higher working seniority as well as higher EE, IRR, DEP, ANX, and DDF scores and lower PA were associated with higher hopelessness. In conclusion, increased hopelessness was associated with higher burnout and alexithymia. Comprehensive strategies should be implemented to support HCWs' mental health and mitigate the negative consequences of alexithymia, burnout, and hopelessness.

Perceived stress and severity of depression mediate the association between alexithymia and suicidal ideation in patients with major depressive disorder

Introduction

Alexithymia and perceived stress have been recognized as risk factors for suicide in patients with major depressive disorder (MDD). However, few studies have been conducted to examine the relationship between these factors.

Methods

A cross-sectional study was conducted on 105 MDD patients. Alexithymia was assessed by the 20-Item Toronto Alexithymia Scale (TAS), perceived stress was assessed by the Perceived Stress Scale (PSS), severity of depression was assessed by the 17-item Hamilton Depression Rating Scale (HAMD), and suicidal ideation was assessed by the self-report Beck Scale for Suicide Ideation (SSI). A sequential mediation model was established to test the mediating effects of perceived stress and severity of depression on the association between alexithymia and suicidal ideation.

Results

81 of the 105 participants (77.14 %) had suicidal ideation. Patients with suicidal ideation had greater difficulty in identifying feelings (DIF) (p = 0.046), higher severity of depression (p = 0.005) and perceived stress (p = 0.003). DIF subscale score of TAS was associated with perceived stress (r = 0.292, p = 0.003), severity of depression (r = 0.349, p < 0.001) and suicidal ideation (r = 0.229, p = 0.012). Sequential mediation model showed that perceived stress and severity of depression mediated the effect of DIF on suicidal ideation.

Conclusions

This study suggests that perceived stress and severity of depression fully mediate the relationship between difficulty in identifying feelings and suicidal ideation in MDD patients.

Alexithymia modulates the attitudes towards odors but not the olfactory abilities or the affective reactions to odors

Although emotion and olfaction are closely linked, only a few studies have investigated olfactory processing in alexithymia, a condition characterized by altered emotional processing. These results do not allow comprehensive conclusions on whether individuals with alexithymia present lower olfactory abilities or only altered affective reactions and awareness of odors. Three pre-registered experiments were conducted to clarify this relation. We assessed olfactory functions, the affective qualities of odors, the awareness of odors, the attitudes towards them, and the ability to form olfactory images in the mind. Bayesian statistics were used to assess differences between low, medium and high alexithymia groups, and Linear Mixed Models (LMMs) were applied to investigate the modulation of the affective and cognitive components of alexithymia. We observed that individuals with a high level of alexithymia presented the same olfactory abilities, and did not show differences in their rating of odors compared to individuals with low alexithymia levels, while they reported lower levels of social and common odor awareness and a more indifferent attitude towards odors. Olfactory imagery was not affected by alexithymia level, and the affective and cognitive components of alexithymia, when considered separately, modulated olfactory perception differently. Learning more about olfactory perception in individuals with alexithymia leads to a better understanding of how alexithymia impacts the perception of hedonic stimuli coming from different sensory modalities. Our results imply that treatment goals for alexithymia should be the enhancement of the conscious perception of odors, supporting the use of mindfulness-based protocols in the alexithymia treatment.

Impact of alexithymia on suicidal ideation among patients with ovarian cancer: a moderated mediation model of self-perceived burden and general self-efficacy

PURPOSE

Suicidal ideation (SI) and alexithymia are common psychological problems among patients with cancer. Studying how alexithymia predicts SI is helpful for its intervention and prevention strategies. The present study aimed to investigate whether self-perceived burden (SPB) mediates the impact of alexithymia on SI and if general self-efficacy moderates the associations of alexithymia with SPB and SI.

METHODS

To measure SI, alexithymia, SPB, and general self-efficacy, 200 patients with ovarian cancer at all stages regardless of the type of treatment completed the Chinese version of the Self-Rating Idea of Suicide Scale, Toronto Alexithymia Scale, Self-Perceived Burden Scale, and General Self-Efficacy Scale in a cross-sectional study. The PROCESS macro for SPSS v4.0 procedure was applied to perform moderated mediation analysis.

RESULTS

SPB significantly mediated the positive impact of alexithymia on SI (a×b = 0.082, 95% confidence interval [CI]: 0.026, 0.157). General self-efficacy significantly moderated the positive association between alexithymia and SPB (β = -0.227, P < 0.001). The mediating role of SPB was gradually reduced as general self-efficacy grew (low: 0.087, 95% CI: 0.010, 0.190; medium: 0.049, 95% CI: 0.006, 0.108; high: 0.010, 95% CI: -0.014, 0.046). Thus, a moderated mediation model involving SPB and general self-efficacy for explaining how alexithymia causes SI was supported.

CONCLUSION

Alexithymia could cause SI by inducing SPB among patients with ovarian cancer. General self-efficacy could attenuate the association between alexithymia and SPB. Interventions aimed at reducing SPB and enhancing general self-efficacy could reduce SI by partially preventing and attenuating the impact of alexithymia.

Core clinical symptoms and suicidal ideation in patients with obsessive-compulsive disorder: A network analysis

INTRODUCTION

Suicidality in obsessive-compulsive disorder (OCD) is underestimated and it is important for clinicians to understand the factors that contribute to suicidal ideation. The present study aimed to estimate a network of the core clinical symptoms of OCD including obsessions, compulsions, and obsessive-compulsive (OC) symptom dimensions, depressive symptoms, and psychological traits, and to examine which symptoms contribute to suicidal ideation in patients with a primary diagnosis of obsessive-compulsive disorder.

METHODS

A total of 444 patients with OCD were assessed with the Yale-Brown Obsessive-Compulsive Scale, the Montgomery-Asberg Depression Rating Scale, and various other measures. Network analysis was conducted to estimate the network of obsessive-compulsive and depressive symptoms, psychological traits including alexithymia and impulsivity, and demographic covariates. Symptoms directly related to suicidal ideation in the network were examined for their relative contribution to suicidal ideation.

RESULTS

Suicidal ideation was directly related to degree of control over compulsive behaviors, distress associated with compulsive behaviors, time spent performing compulsive behaviors, and unacceptable thoughts, along with depressive symptoms and alexithymia. In the network of OC and depressive symptoms the most central symptoms among the former were interference due to compulsive behaviors and interference due to obsessive thoughts, and among the latter were pessimistic thoughts and reported sadness.

CONCLUSION

The findings suggest that along with depressive symptoms and alexithymia, compulsions and unacceptable thoughts dimension may contribute to suicidality, and thus, should be carefully monitored in patients with OCD.

Segregation, integration and balance in resting-state brain functional networks associated with bipolar disorder symptoms

Bipolar disorder (BD) is a serious mental disorder involving widespread abnormal interactions between brain regions, and it is believed to be associated with imbalanced functions in the brain. However, how this brain imbalance underlies distinct BD symptoms remains poorly understood. Here, we used a nested-spectral partition (NSP) method to study the segregation, integration, and balance in resting-state brain functional networks in BD patients and healthy controls (HCs). We first confirmed that there was a high deviation in the brain functional network toward more segregation in BD patients than in HCs and that the limbic system had the largest alteration. Second, we demonstrated a network balance of segregation and integration that corresponded to lower anxiety in BD patients but was not related to other symptoms. Subsequently, based on a machine-learning approach, we identified different system-level mechanisms underlying distinct BD symptoms and found that the features related to the brain network balance could predict BD symptoms better than graph theory analyses. Finally, we studied attention-deficit/hyperactivity disorder (ADHD) symptoms in BD patients and identified specific patterns that distinctly predicted ADHD and BD scores, as well as their shared common domains. Our findings supported an association of brain imbalance with anxiety symptom in BD patients and provided a potential network signature for diagnosing BD. These results contribute to further understanding the neuropathology of BD and to screening ADHD in BD patients.

Externalising Behaviours, Impulsivity, Alexithymia, and Emotional Dysregulation in Adolescents' Suicidality

Objective

suicide represents the second leading cause of death among adolescents (WHO, 2021). A deeper understanding of the characteristics that lead to it is crucial to increase the ability of clinicians in evaluating, treating, and preventing it. The objective of this study is to analyze the differences in impulsivity, externalizing behaviors, emotion dysregulation, and alexithymia between two groups of adolescents, the first presenting suicidal ideation (SI), the second presenting at least one suicide attempt (SA), in an ideation-to-action framework.

Method

we conducted a retrospective study with 190 adolescents (M= 14.5, SD _age = 1.63; SI: n = 97, SA: n = 93). All were hospitalized in the Complex Operative Child Neuropsychiatry Hospital Unit (UOC-NPI) of the Hospital-University of Padua. Data were collected using the Youth Self-Report (YSR 11-18), Barratt's Impulsiveness Scale (BIS-11) and the Toronto Alexithymia Scale (TAS-20) questionnaires.

Results

the SA group obtained higher clinical scores in the YSR "rule-breaking behavior" and "conduct problems" scales, and in total TAS-20.

Conclusions

the role of externalizing problems and alexithymia could open new frontiers in the understanding of suicide. These new data could be useful for the implementation of early screening protocols and for directing clinical interventions, promoting greater emotion regulation and anger management skills among patients.

The Relationship Between Bullying Victimization and Perpetration and Non-suicidal Self-injury: A Systematic Review

Experience of bullying may be a significant risk factor for non-suicidal self-injury (NSSI). This study had three aims: to systematically investigate the association between bullying and NSSI, analyze the possible mechanisms underlying the two phenomena, and evaluate any differences between bullying victimization and bullying perpetration with respect to NSSI. A systematic search about the association between bullying victimization and perpetration and NSSI was conducted using specific databases (PubMed, Scopus, Science Direct). The following keywords were used in all database searches: "bullying" AND "NSSI" OR "peer victimization" and NSSI. The searches in PubMed, Scopus and Science Direct revealed a total of 88 articles about bullying or peer victimization and NSSI. However, only 29 met our inclusion criteria and were used for the present review. Overall, all studies examined victimization; four studies also evaluated the effects of perpetration and one included bully-victims. According to the main findings, both being a victim of bullying and perpetrating bullying may increase the risk of adverse psychological outcomes in terms of NSSI and suicidality in the short and the long run. To the best of our knowledge, this is the first review to systematically evaluate the relation between bullying victimization/perpetration and NSSI. The main results support a positive association. Future research should evaluate the possible role of specific mediators/moderators of the association between experience of bullying and NSSI.

Suicidal Ideation and Obsessive-Compulsive Disorder: Links and Knowledge

Suicidal ideation (SI) is understudied in obsessive-compulsive disorder (OCD). Nonetheless, evidence suggests increased risk for SI in individuals with OCD compared to the general population. Understanding the relationship between SI and OCD involves investigating risk factors associated with SI. Furthering knowledge of links is essential for enhancing outcomes and decreasing experiences of SI through improving treatment interventions. Additionally, increasing awareness of factors that lead SI to suicide attempts (SA) is vital. To best illustrate the current state of knowledge, this scoping review examines risk factors for SI, including symptom profiles or phenotypes, comorbid diagnoses, sociodemographic and lifestyle factors, childhood trauma, and genetic and familial contributions. Important treatment considerations for targeting SI within the context of OCD are detailed with respect to the current evidence for psychotherapy, pharmacology, brain stimulation, and neurosurgery. Gaps in the literature and future directions are identified, broadly with respect to studies examining the treatment of SI within the context of OCD, particular OCD phenotypes, and factors influencing SI in pediatric OCD. Due to the relative novelty of this area of exploration, many unknowns persist regarding onset of SI in OCD, factors contributing to the maintenance of SI in OCD, and relevant treatment protocols. Findings suggest that individuals with previous SI or SA, history of childhood trauma, significant life stress, and psychiatric comorbidities, particularly depression, should be closely monitored and screened for SI.

Suicidality in adolescents with onset of anorexia nervosa

OBJECTIVES

The mortality rate in patients with anorexia nervosa (AN) is 5 to 10 times higher than in general population and, suicide is one of the main causes of death. We evaluated the prevalence of suicidality (ideation, self-injurious behaviour, suicidal attempts) in 100 adolescents with onset of AN and we explored the correlation between suicidality, severity of AN symptoms and psychiatric comorbidity.

METHODS

We subdivided AN patients into restrictive (R-AN; n = 66) and restrictive atypical (A-AN; n = 34), according to the European Guidelines criteria. Assessment was performed using the eating disorder inventory 3rd version, the schedule for affective disorders and schizophrenia for school-age children-present and lifetime version interview, and the Columbia-suicide severity rating scale. Fisher's exact test and Mann-Whitney test (with correction for multiple testing) were used to compare the distribution of categorical and continuous variables between R-AN and A-AN patients, and between patients with vs. without suicidal behaviours.

RESULTS

Twenty-seven patients (27%) presented suicidality as clinical feature, expressed as at least one of the following: suicidal ideation (24%), self-cutting (19%), and suicidal attempt (6%). Patients with suicidality showed greater severity of psychiatric symptoms related to AN psychopathology and presented psychiatric comorbidity, especially depression, more often than patients who did not reported suicidality (70,4% vs 29,6%). No significant differences in terms of suicidal behaviours and AN-specific psychopathology were found between R-AN and A-AN.

CONCLUSIONS

Suicidality in adolescent patients with R-AN and A-AN seems to be related to ED symptoms. These data highlight the importance of screening for suicidality among adolescents at onset of AN, and confirms that A-AN should not be considered a milder disease.

LEVEL OF EVIDENCE

Level IV: Evidence obtained from multiple time series analysis such as case studies. (NB: Dramatic results in uncontrolled trials might also be regarded as this type of evidence).

Association between Alexithymia and Depression among King Khalid University Medical Students: An Analytical Cross-Sectional Study

Alexithymia is a condition in which a person is unable to explain his/her emotions, bodily sensations, or discuss sentiments. This study aims to determine the prevalence of alexithymia and its relationships with socio-demographics and depression among medical students. A cross-sectional survey was conducted among medical students at King Khalid University (KKU), Saudi Arabia. A stratified random sampling technique was utilized for data collection using the Toronto Alexithymia Scale (TAS-20) and the Patient Health Questionnaire-9 (PHQ-9). A multiple logistic regression model was used to identify the factors associated with alexithymia. A total of 333 students participated in this study, almost two-thirds (64.6%) were from clinical years, and 51.4% were females. The prevalence of alexithymia and depression was 47.4% and 88.9%, respectively. Regression analysis showed females had a doubled risk (OR = 2.09), and students with high-income status showed less probability of having alexithymia (OR = 0.39), whereas people with chronic health problems showed a doubled risk for alexithymia (OR = 2.04). Moreover, depression was significantly associated with alexithymia (OR = 1.91). Our study revealed that the prevalence of alexithymia was high along with depression among studied samples. This raises attention towards finding measures to reduce it for the better performance of students and to avoid psychological problems in the future.

Prosocial behavior is associated with transdiagnostic markers of affective sensitivity in multiple domains

Prosocial behaviors-actions that benefit others-fundamentally shape our interpersonal interactions. Psychiatric disorders have been suggested to be related to prosocial disturbances, which may underlie many of their social impairments. However, broader affective traits, present to different degrees in both psychiatric and healthy populations, also have been linked to variability in prosociality. Therefore, it is unclear to what extent prosocial variability is explained by specific psychiatric disorders relative to broad affective traits. Using a computational, transdiagnostic approach in two online studies, we found that participants who reported being more affectively reactive across a broad cluster of traits manifested greater frequencies of prosocial actions in two different contexts: They reported being more averse to harming others for profit, and they were more willing to exert effort to benefit others. These findings help illuminate the profile of prosociality across psychiatric conditions as well as the architecture of prosocial behavior in healthy individuals.

Exposure of Child Maltreatment Leads to a Risk of Mental Illness and Poor Prognosis in Taiwan: A Nationwide Cohort Study from 2000 to 2015

Objective: To investigate whether children with maltreatment exposure were associated with the risk of psychiatric disorders, suicide, and death. Methods: A retrospective cohort study was conducted, with 1592 child maltreatment cases and 6368 comparison cohort (1:4) matched for gender, age, and index year, from the Longitudinal Generation Tracking Database (LGTD2000) sampled from Taiwan National Health Insurance Research Database (NHIRD) in 2000, backtracking between 2000−2015 in Taiwan. The stratified Cox regression model was used to compare the risk of developing a mental illness and poor prognosis during the 15 years of follow-up. Results: There were 473 in the cohort with child maltreatment (675.10 cases per 100,000 person years) and 1289 in the comparison cohort (453.82 cases per 100,000 person years) that developed mental illness and poor prognosis. The stratified Cox regression model revealed that the adjusted hazard ratio (HR) was 1.91 to 11.76 (p < 0.05) after adjusting for monthly income level, occupation, and CCI after violence. Conclusion: Exposure to child maltreatment is associated with the risk of psychiatric disorders, but not suicide or death. This finding could be a reminder for clinicians about the mental health problems in patients with child maltreatment.

Emotional intelligence, alexithymia and suicidal ideation among depressive patients

BACKGROUND

Depression is more than just sentiment sad or passing a rough patch. It is a serious psychological wellbeing disorder that needs curative care and maintenance. Emotional Intelligence (EI) is a comprehensive personality construct denoting the capability to perceive and control affects within the self. Alexithymia is another personality construct that refers to the difficulty of recognizing and expressing feelings, with an outside oriented thinking style. Suicidal ideation is defined as thinking of appealing in conduct intentional to end one's life.

AIM

The current study aimed to examine the relationship between emotional intelligence, alexithymia and suicidal ideation among depressive patients.

DESIGN

A descriptive correlation design was utilized.

SETTING

This study was conducted at the Psychiatric Outpatient Clinic in El Ahrar Hospital, Alsharkia Governorate, Egypt.

SUBJECTS

A purposeful sample of 65 depressed patients was recruited for this study.

TOOLS

Data were collected by using four tools: Socio-demographic Data Sheet, Emotional Intelligence Scales, Toronto Alexithymia Scale (TAS-20) and Suicidal Ideation Scale.

RESULTS

The majority of depressed patients were having alexithymia and having low emotional intelligence. Emotional intelligence was statistically significantly negatively correlated with alexithymia and suicidal ideation. Nevertheless, alexithymia was statistically significantly positively correlated with suicidal ideation. It was statistically significantly positively predictor of suicidal ideation and alexithymia, while it was statistically significantly negatively predictor of suicidal ideation and emotional intelligence.

CONCLUSION

Lower emotional intelligence led to higher suicidal ideation in depressive patients. Increasing alexithymia in patients with depressive disorders caused an increase in their suicidal ideation. Therefore, it is recommended implementing a training program such as mindfulness and emotional intelligence skills for patients to enhance their emotional intelligence.

Impact of the COVID-19 pandemic on people living with migraine: Results of the MiCOAS qualitative study

BACKGROUND

The coronavirus disease 2019 (COVID-19) pandemic is an ongoing global health crisis that has had a range of impacts on people living with migraine.

METHODS

Qualitative interviews performed as part of the Migraine Clinical Outcome Assessment System project, a multi-stage Food and Drug Administration-grant funded program to develop a patient-centered core set of outcome measures for use in migraine clinical trials, offered an opportunity to explore the experience of living with migraine during the pandemic as well as to examine whether migraine treatment priorities, symptoms, and associated disability changed due to the pandemic. Semi-structured interviews were conducted in the United States between the summer and fall of 2020 with 40 individuals with self-reported, medically diagnosed migraine who self-reported that they had not tested positive for or been diagnosed with COVID-19.

RESULTS

Seventy percent (n = 28) of the sample reported ≥1 pandemic-related impact on their life with migraine. Fourteen participants reported both positive and negative impacts, twelve reported negative impacts only, and two reported positive impacts only. Among those reporting ≥1 pandemic-related impact, nine participants (32%) reported more frequent and five (17%) reported less frequent migraine attacks. Other negative impacts included interrupted medical care (n = 9; 32%), and greater stress (n = 13; 46%). The most frequent positive impact reported was greater access to health care (n = 8; 29%). Ictal and interictal symptoms were not noted to change due to the pandemic, but some respondents reported less disability due to increased flexibility of schedules and reduced expectations. Treatment priorities did not change due to the pandemic.

CONCLUSION

The global COVID-19 pandemic has resulted in both negative and positive impacts for people living with migraine. Lessons to be considered when moving into a post-pandemic world include benefits of and satisfaction with telehealth and the benefits and importance of healthy lifestyle habits and flexibility such as improved sleep, reduced stress, and fewer social expectations.

Relationship between stress and alexithymia, emotional processing and negative/positive affect in medical staff working amid the COVID-19 pandemic

The psychological burden of the COVID-19 pandemic may have a lasting effect on emotional well-being of healthcare workers. Medical personnel working at the time of the pandemic may experience elevated occupational stress due to the uncontrollability of the virus, high perceived risk of infection, poor understanding of the novel virus transmission routes and unavailability of effective antiviral agents. This study used path analysis to analyze the relationship between stress and alexithymia, emotional processing and negative/positive affect in healthcare workers. The sample included 167 nurses, 65 physicians and 53 paramedics. Sixty-two (21.75 %) respondents worked in COVID-19-designated hospitals. Respondents were administered the Toronto Alexithymia Scale-20, Cohen's Perceived Stress Scale, Emotional Processing Scale, and the Positive and Negative Affect Schedule. The model showed excellent fit indices (χ2 (2)=2.642, p=0.267; CFI=0.999, RMSEA=0.034, SRMR=0.015). Multiple group path analysis demonstrated physicians differed from nurses and paramedics at the model level (X2diff (7)=14.155, p<0.05 and X2diff (7)=18.642, p<0.01, respectively). The relationship between alexithymia and emotional processing was stronger in nurses than in physicians (difference in beta=0.27; p<0.05). Individual path χ2 tests also revealed significantly different paths across these groups. The results of the study may be used to develop evidence-based intervention programs promoting healthcare workers' mental health and well-being.

The role of alexithymia as a risk factor for self-harm among adolescents in depression - A systematic review

INTRODUCTION

Considering the suggested role of alexithymia in increasing the risk of self-harm, especially when depression is also present, and that rates of self-harm tend to peak in adolescence, the aim of this systematic review was to synthetize the most relevant research studies on this topic and provide an understanding on whether alexithymia can be considered as an important risk factor for non-suicidal self-harm among adolescents with depression.

METHODS

Searches were conducted in PubMed, Web of Science, and PsycINFO, resulting in 290 records. After removal of duplicates, 273 records were left and after reading the titles and abstracts, 231 articles were excluded, leaving 42 articles that were read in full. Of these 42, nine articles were included in this review.

RESULTS

The sample of this review consists of eight case-control studies and one cross-sectional and longitudinal survey. All nine studies concluded that the most important variables associated with self-harming behavior were depression and alexithymia, among all other variables assessed. The self-harming groups showed significantly higher scores on alexithymia (overall and particularly Factor 1- difficulties identifying feelings and differentiating them from bodily sensations), when compared to the control (no self-harming) groups, and the mean depression scores for self-harming groups were significantly higher than those for non-harming groups. All nine studies included in this review shared the limitation of self-reported information.

CONCLUSION

These results indicate that alexithymia is a risk factor for non-suicidal self-harm among adolescents with depression, even when other variables were also inspected, and may be a prevention and therapeutic target in the future.

Cultural Adaptation and Validation of the Urdu Version of the Cognitive Emotion Regulation Questionnaire (CERQ) in Male Patients With Substance Use Disorders (SUDs) in Pakistan

BACKGROUND

Adults with substance use disorders (SUDs) often have co-occurring mental health problems. Emotion regulation may play a vital role in mental health problems. The Cognitive Emotion Regulation Questionnaire (CERQ) is a widely used measure for assessing cognitive emotion regulation. However, it has not been used in Pakistan on patients with co-occurring SUDs and mental health issues. The present study aims to translate and adapt the CERQ into the Urdu language and to determine its reliability and convergent validity in a sample of male patients with SUDs in Pakistan.

METHOD

Participants completed a demographic information form, the CERQ, the Depression, Anxiety, and Stress Scale Short Form [DASS-21)], and the Rosenberg Self-Esteem Scale [RSES)] in Urdu.

RESULTS

Male participants (N = 237) 18-50 years of age (M = 29.8, SD = 8.1) were recruited from four substance use disorder treatment centers and hospitals in Karachi. The reliability of the Urdu version of the CERQ was based on an examination of its internal consistency reliability (Cronbach's α) and test-retest reliability for both the total scale and its subscales. Internal consistency for the CERQ total (α = 0.80) was adequate, as it was for subscales of self-blame, (0.76) acceptance (0.78), rumination (0.72), positive refocusing (0.79), focus on planning (0.89), positive reappraisal (0.81), putting into perspective (0.83), catastrophizing (0.73), and other blame (0.70). The 10-14 day test-retest reliability of the CERQ total score was 0.86. Higher CERQ scores were significantly (ps < 0.001) negatively associated with DASS-21depression (r = -0.24), anxiety (r = -0.23), and stress (r = -0.27) subscales, as well as the DASS-21 total score (r = -0.26) and positively associated with the RSES self-esteem score (r = 0.30).

CONCLUSION

The Urdu version of the CERQ is a reliable measure for investigating cognitive emotion regulation strategies related to mental health and SUDs in Pakistan.

Gambling Disorder in an Italian Population: Risk of Suicide Attempts and Associated Demographic-Clinical Factors using Electronic Health Records

To identify the demographic and clinical characteristics associated with access to Emergency Departments for Suicide Attempt in a cohort of patients with Gambling disorders. We used electronic health records of inpatient and outpatient services to identify individuals who received a diagnosis of gambling disorder (ICD-9 or ICD-10 codes) in the Metropolitan area of Bologna from 2009 to 2019. In this cohort we identified accesses to Emergency Departments for suicide attempt through cross-matching with electronic records. We calculated Crude Suicide Attempt Rates; we also included the demographic-clinical variables in a multivariate Poisson regression. We identified 692 patients with a diagnosis of gambling disorder and a total of 2733 Person Years. The Crude Suicide Attempt Rate per 1000 Person Years was 9.17 (95% CI 6.20-13.58), higher for females and much higher than the general population (incidence rate ratio = 93.72). The multivariate analysis showed a higher risk of suicide attempt in the year following the first contact with a clinical service, in patients younger than 45 years, with alcohol use disorders and personality disorders. This study evidenced a high risk of access to Emergency Departments for suicide attempt in individuals with a diagnosis of gambling disorder and highlighted important demographic and clinical factors that should be considered when evaluating suicide risk in this population.

Suicide probability in psychiatric patients' primary caregivers: The role of care burden, alexithymia and some risk factors

BACKGROUND

Although suicidal ideation seems to be related with both burden of care and alexithymia, there is no study investigating the correlation between these factors and suicide probability in informal caregivers of psychiatric patients in the literature.

AIM

In this study, it was aimed to determine the suicide probability in psychiatric patients' primary caregivers, and to evaluate the effects of care burden, alexithymia and some risk factors on suicide probability.

METHODS

This study was conducted with 262 caregivers between February 2019 and December 2019. Data were collected with the Personal Information Form, Suicide Probability Scale, Zarit Burden Interview, Toronto Alexithymia Scale.

RESULTS

The mean score the caregivers obtained from the Suicide Probability Scale was 79.75 ± 59.29, and 17.9% of them were at risk for suicide. Also, caregivers' suicide probability was related to variables such as caregivers' sex, economic status, presence of any disease, duration of care, and patients' education level, psychiatric diagnosis, duration of illness, presence of physical illness, compliance with treatment. In addition, caregivers' burden and alexithymia levels were significantly associated with the participating caregivers' suicide probability.

CONCLUSIONS

This study demonstrates that approximately one out of every five caregivers was at risk for suicide. Therefore, hospital and community-based intervention strategies to support caregivers should be developed.

Alexithymia Is Associated With Internalizing Disorders in a Clinical Adolescent Outpatient Sample

ABSTRACT

The aim of this study was to investigate alexithymic traits in an adolescent clinical sample with internalizing and externalizing disorders. The study group consisted of 125 adolescents aged between 12 and 17 years who applied at our outpatient unit and diagnosed with an internalizing or externalizing disorder. The healthy control group consisted of 53 adolescents with no psychiatric disorder. All subjects fulfilled the Alexithymia Questionnaire for Children (AQC). Total AQC scores were higher in the study group than in the control group. When we divided the study group into two groups as internalizing and externalizing disorders, total AQC scores, AQC-difficulty identifying feelings, and AQC-difficulty describing feelings were significantly higher in the internalizing disorder group than in the externalizing disorder group. AQC-externally oriented thinking scores were significantly higher in the externalizing disorder group than in the internalizing disorder group. In future research, it would be useful to further increase understanding of alexithymia and its association with psychiatric disorders in adolescence.

Improving the measurement of alexithymia in autistic adults: a psychometric investigation of the 20-item Toronto Alexithymia Scale and generation of a general alexithymia factor score using item response theory

BACKGROUND

Alexithymia, a personality trait characterized by difficulties interpreting emotional states, is commonly elevated in autistic adults, and a growing body of literature suggests that this trait underlies several cognitive and emotional differences previously attributed to autism. Although questionnaires such as the 20-item Toronto Alexithymia Scale (TAS-20) are frequently used to measure alexithymia in the autistic population, few studies have investigated the psychometric properties of these questionnaires in autistic adults, including whether differential item functioning (I-DIF) exists between autistic and general population adults.

METHODS

This study is a revised version of a previous article that was retracted due to copyright concerns (Williams and Gotham in Mol Autism 12:1-40). We conducted an in-depth psychometric analysis of the TAS-20 in a large sample of 743 cognitively able autistic adults recruited from the Simons Foundation SPARK participant pool and 721 general population controls enrolled in a large international psychological study. The factor structure of the TAS-20 was examined using confirmatory factor analysis, and item response theory was used to generate a subset of the items that were strong indicators of a "general alexithymia" factor. Correlations between alexithymia and other clinical outcomes were used to assess the nomological validity of the new alexithymia score in the SPARK sample.

RESULTS

The TAS-20 did not exhibit adequate model fit in either the autistic or general population samples. Empirically driven item reduction was undertaken, resulting in an 8-item general alexithymia factor score (GAFS-8, with "TAS" no longer referenced due to copyright) with sound psychometric properties and practically ignorable I-DIF between diagnostic groups. Correlational analyses indicated that GAFS-8 scores, as derived from the TAS-20, meaningfully predict autistic trait levels, repetitive behaviors, and depression symptoms, even after controlling for trait neuroticism. The GAFS-8 also presented no meaningful decrement in nomological validity over the full TAS-20 in autistic participants.

LIMITATIONS

Limitations of the current study include a sample of autistic adults that was majority female, later diagnosed, and well educated; clinical and control groups drawn from different studies with variable measures; only 16 of the TAS-20 items being administered to the non-autistic sample; and an inability to test several other important psychometric characteristics of the GAFS-8, including sensitivity to change and I-DIF across multiple administrations.

CONCLUSIONS

These results indicate the potential of the GAFS-8 to robustly measure alexithymia in both autistic and non-autistic adults. A free online score calculator has been created to facilitate the use of norm-referenced GAFS-8 latent trait scores in research applications (available at https://asdmeasures.shinyapps.io/alexithymia ).

Borderline personality disorder and adolescent suicide attempt: the mediating role of emotional dysregulation

BACKGROUND

Emotional dysregulation seems to be a core feature of Borderline Personality Disorders (BPD). In addition, recent research in the adolescent population has shown that suicidal behaviours have been associated with maladaptive strategies of emotion regulation.

METHODS

This study examined the relative contributions of emotional dysregulation to suicide attempt history in a clinical sample of borderline adolescents. Data were analyzed from 85 participants of the Collaborative European Research Network on Borderline Personality Disorder. Participants completed measures of BPD traits and symptoms, suicide behaviours, emotional dysregulation, attachment styles and lifetime depressive disorders.

RESULTS

In an SEM model, lifetime depressive disorders and insecure attachment styles have a significant direct effect on lifetime suicide attempt, but only lifetime depressive disorders have an indirect effect through emotion dysregulation. The results suggest that emotional dysregulation has a mediating role in suicide attempts among BPD adolescents.

CONCLUSIONS

These findings call for the development of interventions targeting the role of emotion dysregulation in effectively predicting and preventing suicidality in borderline adolescents.

Prevalence and correlates of current suicide risk in an international sample of OCD adults: A report from the International College of Obsessive-Compulsive Spectrum Disorders (ICOCS) network and Obsessive Compulsive and Related Disorders Network (OCRN) of the European College of Neuropsychopharmacology

INTRODUCTION

Obsessive-compulsive disorder (OCD), characterized by repetitive anxiety-inducing intrusive thoughts and compulsive behaviors, is associated with higher suicide ideation and suicide attempts than the general population. This study investigates the prevalence and the correlates of current suicide risk in adult outpatients in an international multisite cross-sectional sample of OCD outpatients.

METHODS

Data were derived from the International College of Obsessive-Compulsive Spectrum Disorders (ICOCS) network's cross-sectional data set (N = 409). Current suicide risk (assessed by Item C of the MINI) and diagnoses of psychiatric disorders were based on DSM-IV. Chi-squared test for categorical variables and t-test for continuous variables were used to make statistical inferences about main features associated with current suicide risk. P < .05 was considered as statistically significant.

RESULTS

The prevalence of current suicidal risk was 15.9%, with equal likelihood in sociodemographic variables, including age and gender. Increased rates of major depression and generalized anxiety disorder were associated to higher current suicide risk. Current suicide risk was also associated with higher severity of OCD, depressive comorbidity, and higher levels of disability. There were no significant differences in treatment correlates-including type of treatment and psychiatric hospitalizations-between the groups of individuals with and without current suicide risk.

CONCLUSION

Our findings suggest that current suicide risk is common in patients with OCD and associated with various forms of pathology. Our work also provides further empirical data to support what is already known clinically: a worse clinical picture characterized by a high severity of OCD, high distress related to obsessions and compulsions, and the presence of comorbidities such as major depression and generalized anxiety disorder should be considered as relevant risk factors for suicide risk.

Understanding the psychological impact of the COVID-19 pandemic and containment measures: An empirical model of stress

Epidemics such as COVID-19 and corresponding containment measures are assumed to cause psychological stress. In a survey during the lockdown in Switzerland (n = 1565), we found substantially increased levels of stress in the population. In particular, individuals who did not agree with the containment measures, as well as those who saw nothing positive in the crisis, experienced high levels of stress. In contrast, individuals who are part of a risk group or who are working in healthcare or in essential shops experienced similar stress levels as the general public. The psychological mechanisms that determine stress, caused by the COVID-19 pandemic and containment measures, are not yet clear. Thus, we conducted a path analysis to gain a deeper understanding of the psychological mechanisms that lead to stress. Experiencing fear of the disease is a key driver for being worried. Our model further shows that worries about the individual, social, and economic consequences of the crisis, strongly boost stress. The infection rate in the canton (i.e., state) of residence also contributes to stress. Positive thinking and perceived social, organizational, and governmental support mitigate worries and stress. Our findings indicate that containment measures increase worries and stress, especially for those who feel that these measures either are not sufficient or go too far. Thus, highlighting positive aspects of the crisis and convincing people of the effectiveness and necessity of mitigation measures can, not only promote compliance, but also reduce stress. Our model suggests that people who feel protected by the authorities have fewer worries, which can, in turn, limit the negative impact of the crisis on mental health.

Community Case Study: Stack Up's Overwatch Program, an Online Suicide Prevention and Peer Support Program for Video Gamers

Traditional mental health services are often not enough to meet the needs of people at risk for suicide, especially in populations where help-seeking is stigmatized. Stack Up, a non-profit veteran organization whose goal is to use video games to bring veterans together, recognized a need in its gaming-focused online community and created the Overwatch Program. This suicide prevention and crisis intervention program is delivered entirely through the Internet by trained community members through Discord text and voice chat. By combining aspects of virtual gaming communities, veteran mental health, and community-based peer support, this program provides an innovative format for implementing crisis intervention and mental health support programs. We describe here the context and features of the program, an ongoing evaluation project, and lessons learned.

Understanding the effects of personality traits on solver engagement in crowdsourcing communities: a moderated mediation investigation

Purpose

Crowdsourcing communities enable companies to post challenges that are completed by solvers (workers); their success depends on engagement, requiring both creativity and effort. This study explores solver engagement in online crowdsourcing communities, advancing the theory of trait engagement by investigating the mediating roles of: (a) task-related self-efficacy in linking conscientiousness, neuroticism and extraversion, with solver engagement, and (b) task complexity in influencing the mediation.

Design/methodology/approach

215 valid responses were obtained from solvers engaged in the popular Chinese crowdsourcing community, Epwk.com, using an online questionnaire. PLS was then used to analyze the data.

Findings

Results show that self-efficacy mediates the relationships for conscientiousness, neuroticism and extraversion, with solver engagement. Moderated mediation analysis revealed that self-efficacy mediates the relationships for: (a) conscientiousness and extraversion, for only solvers with high task complexity; and (b) neuroticism, for only solvers with low task complexity.

Originality/value

The authors’ findings underscore the importance of accounting for solvers' situational contexts when examining the relationships between personality, self-efficacy and solver engagement in online crowdsourcing communities.

Emotion dysregulation and suicidality in eating disorders

OBJECTIVE

Suicidality in eating disorders (EDs) is high, and identification of therapeutically targetable traits associated with past, current, and future suicidality is of considerable clinical importance. We examined overall and ED subtype-specific associations among suicidal ideation, suicide attempts, and general and specific aspects of emotion dysregulation in a large sample of individuals with ED, at presentation for treatment and 1-year follow-up.

METHOD

Using registry data from 2,406 patients, scores on the Difficulties in Emotion Dysregulation Scale (DERS) at initial registration were examined as predictors of recent suicidal ideation and self-report lifetime suicide attempts. Associations were examined in the full sample and in each ED subtype. In 406 patients, initial DERS scores were examined as predictors of suicidality at 1-year follow-up.

RESULTS

Overall DERS was associated with suicidal ideation and suicide attempts, even when adjusting for ED psychopathology and current depression. Perceived lack of emotion regulation strategies showed unique associations with suicidal ideation and suicide attempts, both in the full sample and in most ED subtypes. Initial DERS was also associated with follow-up suicidal ideation and suicide attempts, although this association did not remain when adjusting for past suicidality.

DISCUSSION

Results suggest that emotion dysregulation may be a potential mechanism contributing to suicidality in EDs, beyond the effects of ED psychopathology and current depression. Although the prevalence of suicidality differs across ED subtypes, emotion dysregulation may represent a risk trait for future suicidality that applies transdiagnostically. Results support addressing emotion dysregulation in treatment in order to reduce suicidality.

The effects of childhood emotional maltreatment and alexithymia on depressive and manic symptoms and suicidal ideation in females with bipolar disorder: emotion dysregulation as a mediator

OBJECTIVES

The relations of childhood emotional maltreatment and alexithymia to the clinical course of bipolar disorder (BD) have been widely recognised. Difficulties in regulating emotions may explain these relationships. The current study evaluated the effects of childhood emotional maltreatment and alexithymia on depressive and manic symptoms as well as suicidal ideation in female patients with BD. Emotion dysregulation was evaluated as a mediating factor.

METHODS

Three hundred hospitalised female patients with a diagnosis of BD provided information regarding their history of childhood emotional maltreatment, alexithymia, difficulties in emotion regulation, depressive and manic symptoms, and suicidal ideation. A series of structural equation models (SEMs) were calculated to assess the associations between these variables.

RESULTS

Childhood emotional abuse and difficulty in identifying feelings were indirectly associated with depressive and manic symptoms as well as suicidal ideation. This association was mediated by emotion dysregulation. This association remained significant after depressive and manic symptoms were controlled in the model.

CONCLUSIONS

This study indicates that patients with BD who experienced emotional abuse during childhood and have difficulties identifying emotions report greater emotion dysregulation. These individuals, in turn, are more likely to experience more severe depressive and manic symptoms as well as suicidal ideation.Key pointsChildhood emotional maltreatment and emotional and clinical factors in bipolar disorder were assessed.Childhood emotional abuse indirectly affected clinical factors via emotion dysregulation.Difficulty in identifying feelings was linked to clinical factors via emotional dysregulation.Emotional dysregulation affected the links of childhood emotional maltreatment and difficulty in identifying feelings on suicidal ideation after controlling for clinical symptoms.Emotional dysregulation dimensions of impulse, strategies, and goals emerge in relation to suicidal ideation.

Inflammation is correlated with abnormal functional connectivity in unmedicated bipolar depression: an independent component analysis study of resting-state fMRI

BACKGROUND

Inflammation might play a role in bipolar disorder (BD), but it remains unclear the relationship between inflammation and brain structural and functional abnormalities in patients with BD. In this study, we focused on the alterations of functional connectivity (FC), peripheral pro-inflammatory cytokines and their correlations to investigate the role of inflammation in FC in BD depression.

METHODS

In this study, 42 unmedicated patients with BD II depression and 62 healthy controls (HCs) were enrolled. Resting-state-functional magnetic resonance imaging was performed in all participants and independent component analysis was used. Serum levels of Interleukin-6 (IL-6) and Interleukin-8 (IL-8) were measured in all participants. Correlation between FC values and IL-6 and IL-8 levels in BD was calculated.

RESULTS

Compared with the HCs, BD II patients showed decreased FC in the left orbitofrontal cortex (OFC) implicating the limbic network and the right precentral gyrus implicating the somatomotor network. BD II showed increased IL-6 (p = 0.039), IL-8 (p = 0.002) levels. Moreover, abnormal FC in the right precentral gyrus were inversely correlated with the IL-8 (r = -0.458, p = 0.004) levels in BD II. No significant correlation was found between FC in the left OFC and cytokines levels.

CONCLUSIONS

Our findings that serum IL-8 levels are associated with impaired FC in the right precentral gyrus in BD II patients suggest that inflammation might play a crucial role in brain functional abnormalities in BD.

Negative emotion dysregulation is linked to the intensity of suicidal ideation in a mixed inpatient sample

BACKGROUND

Suicide has been associated with dysfunctional strategies for emotion regulation but, so far, research findings have been inconclusive.

METHODS

To investigate how difficulties in emotion regulation impact suicidal ideation (SI) and behavior, 111 psychiatric inpatients were enrolled. Affective instability (AI), emotional impulsivity (EI), and negative and positive emotionality (NE and PE) were measured by the RIPoSt-40 questionnaire; the first three subscales have been summed to form a total negative emotion dysregulation (NED) score.

RESULTS

In the sample, 55 subjects reported at least one-lifetime suicide attempt; 50 patients were diagnosed with mood-disorder (MD), 30 with the schizophrenia-spectrum disorder (SSD), and 15 with personality-disorder (PD). Diagnostic groups differed for NED scores (p=.008) but not for PE (p>0.05), with patients suffering from PD having higher scores (p=0.03). Compared to non-attempters, lifetime-suicide attempters were 6.5 times more likely to have a personality disorder (95% CI=1.34/31.83). Partial correlation analyses, controlling for the presence of suicide attempts, showed that lifetime SI-intensity score was significantly and positively associated with NED (r=.39, p<.001), AI (r=.40, p<.001), and NE (r=.42, p<.001). NED scores (p=.001) and the presence of lifetime suicide attempts (p<.001) were independently associated with lifetime SI-intensity scores.

LIMITATIONS

The lack of a non-clinical control group and the cross sectional nature of the study limits the generalizability of the results.

CONCLUSION

Our findings support the hypothesis that negative emotion dysregulation is independently associated with SI and behavior. Negative emotion dysregulation should be targeted in suicide prevention.

The Need for Collective Awareness of Attempted Suicide Rates in a Warming Climate

Background: Climate factors may offer a stronger explanation of the variations in suicide rates compared with economic variables, even in the case of patients admitted involuntarily. Aims: We assessed the role of temperature as a determinant of the increased prevalence of suicide attempts (SA). Method: The sample comprised all cases of hospitalization for SA at the Psychiatric Clinic of the IRCCS Ospedale Policlinico San Martino between August 2013 and July 2018. For ambient temperature, data were provided by the Meteorological Observatory of the University of Genoa. Results: We noted a peak in suicides that was typically found in late spring and early summer due to global warming. Limitations: Other environmental/psychological factors contributing to the onset of an acute clinical event were not considered. The cross-sectional design of the study is another limitation. Conclusion: Further studies are needed to clarify the impact of climatic factors on suicide behavior and implement early intervention and preventive strategies for mental health.

Reminiscence therapy-based care program for reducing anxiety and depression in glioma survivors: A randomized controlled trial

This study aimed to evaluate the effect of reminiscence therapy-based care (RTBC) program on anxiety, depression, patients satisfaction, and survival benefit in glioma patients after tumor resection.A total of 150 eligible glioma patients were randomized into the RTBC group (N = 75, receiving RTBC) and the control care (CC) group (N = 75, receiving CC). Interventions were performed twice a month for 12 months. Anxiety was evaluated by Hospital Anxiety and Depression Scale (HADS) for anxiety score and Zung self-rating anxiety scale (SAS) score; meanwhile, depression was evaluated by HADS for depression score and Zung self-rating depression scale (SDS) score; additionally, patients satisfaction was scored. A 36-month follow-up was performed, and accumulating overall survival (OS) were calculated.Both anxiety level and depression level were reduced in the RTBC group compared with the CC group at month 9 and month 12 (all P < .05); meanwhile, the proportion of anxious patients and depressed patients were decreased in the RTBC group compared with the CC group at month 12 (all P < .05). Moreover, patients satisfaction scores were increased in the RTBC group compared to the CC group at month 6, month 9, and month 12 (all P < .05). Additionally, accumulating OS showed an increasing tendency in the RTBC group compared to the CC group, but no statistical significance was observed (P = .186).RTBC program ameliorates anxiety, depression, and promotes patients satisfaction in glioma patients after tumor resection.

The use of antidepressant medications for Bipolar I and II disorders

Given that the patterns and clinical correlates related to antidepressant drugs (ADs) prescription for Bipolar Disorder (BD) remain generally unclear, this study aimed to compare socio-demographic and clinical features of BD patients treated vs. not treated with ADs. The sample consists of 287 currently euthymic bipolar patients. Among participants (mean age=51.9±15.02), 157 54.7% were receiving ADs. Based on the main findings, subjects given ADs were older and more frequently retired than those without receiving ADs. Moreover, patients given ADs were more likely to have had a first major depressive episode. Lifetime substance abuse/dependence history was less frequently reported among patients given ADs. Furthermore, ADs given patients had a higher number of affective episodes, and longer duration of their illness. Additionally, subjects treated with ADs reported higher hopelessness levels, and lower positive reinterpretations than those who were not treated with ADs. Factors associated with ADs-use by multivariate modeling were reduced personal autonomy (OR=.070), and hopelessness levels (OR=1.391). These results may help clinicians to better understand the clinical correlates of BD subtypes and improve their differential management. Additional studies are needed to replicate these findings, and facilitate the differential trajectories of BD patients based on socio-demographic/clinical profiles.

The Association Between Personality Traits and Dietary Choices: A Systematic Review

Increasing evidence shows how diet may play a role in improving health including mental health. Of note, personality may influence the type of diet and consequently the prognosis of medical and psychiatric conditions. The purpose of the present systematic review is to summarize the available data regarding the influence of personality on dietary habits affecting health outcomes. A search in the main databases was conducted matching the terms "personality," "personality traits" with "food choices," "food preferences," "diet," and "dietary habits." A total of 1856 articles were screened, and 24 articles were finally included. Exclusion criteria consisted of studies on animals or children, studies about eating disorders, types of diet not clearly associated with health outcomes, and studies for marketing reasons. Several studies showed that personality traits can influence both dietary choices and the type of diet, including the preference for healthy or unhealthy food. Unfavorable personality traits such as neuroticism and alexithymia (the inability to identify and describe emotions) were associated with unhealthy diet habits such as low consumption of fruit and vegetables, and the increased consumption of sugar and saturated fats. Personality seems to play a role in food selection and in the propensity to change diet. The interpretation of these results should be weighted by the different cultural contexts in which the studies were conducted and the extreme heterogeneity of tools used to assess personality and food preferences. Future research should clarify how personality can affect diet in specific populations such as patients with severe psychiatric disorders.

Association Between Alexithymia, Social Support, and Duration of Methamphetamine Use Among Male Methamphetamine-Dependent Patients

Introduction: China has 1.18 million methamphetamine abusers. Among the illegal drugs in China, methamphetamine has the highest abuse rate. Although previous studies have indicated a positive relationship between alexithymia and declining social support, the incidence of alexithymia, the total duration of methamphetamine dependence, social support, and the relationships between them among methamphetamine-dependent patients in the Chinese population have been rarely reported. Methods: A total of 113 methamphetamine-dependent patients (all male, mean age 30.45 ± 3.81 years) were enrolled in this cross-sectional study. General demographic data were collected. Alexithymia and social support were measured by Toronto Alexithymia Scale and Social Support Rating Scale. Results: Duration of methamphetamine use among Chinese male methamphetamine-dependent patients in compulsory detoxification was 8.01 ± 3.80 years on average, 23% (26/113) methamphetamine-dependent patients were considered to have alexithymia personality traits. Compared with short-duration methamphetamine-dependent patients (≤8 years), long-duration methamphetamine-dependent patients (> 8 years) were characterized by older age, higher incidence of alexithymia, less subjective social support and support availability, and greater difficulty in identifying feelings. The results of correlation analysis and multiple linear regression analysis indicated that the total duration of methamphetamine use was positively correlated with difficulty in identifying feelings, but negatively correlated with subjective social support. Conclusions: This study provides support for an association between the duration of methamphetamine use and difficulty in identifying feelings or subjective social support. Although the causality is still unclear, this finding should be considered in the psychotherapy of methamphetamine rehabilitation.

Serum Lipid Levels and Suicide Attempts Within 2 Weeks in Patients With Major Depressive Disorder: Is There a Relationship?

The potential correlation between serum lipid profiles and suicidal tendencies has been previously reported, however, it is unclear whether serum lipid profiles have definite relevance to recently attempted suicides in individuals suffering from major depressive disorder (MDD). In this study, the relationship between blood lipids and suicide attempts in first-episode MDD patients in research were used to examine whether there is a connection. The cross-sectional study recruited 580 patients at the time of their first episode, measuring up to the diagnostic standard of MDD. Baseline demographic, clinical data, and blood lipid level data were collected. Depression severity was measured with the Hamilton Depression Rating Scale (HAMD). Our results revealed that the level of TC may be identified as a promising and effective biomarker for first-episode MDD suicide risk, suggesting that screening of serum lipid profiles in depressive patients is essential for suicide prevention.

Prevalence of post-traumatic stress disorder after earthquakes among the elderly in China: A meta-analysis

BACKGROUND

The study aims to investigate the occurrence of post-traumatic stress disorder (PTSD) after earthquakes among the elderly.

METHODS

Data from cross-sectional studies focusing on the prevalence of PTSD after earthquakes among the elderly were collected from PubMed, EMBASE, Cochrane Library, and China National Knowledge Infrastructure in December 2019. The search terms included post-traumatic stress disorder, earthquake, and elderly. This study used Review Manager 5.0 to evaluate the impact of the results. In addition, forest plots, sensitivity analysis, and bias analysis were carried out on the included articles. The combined estimate of the risk ratio and the standard deviation of the 95% confidence interval (95% CI) were measurements of the size of the effect.

RESULTS

There were 4,834 patients included from 10 eligible studies. The sample sizes of PTSD group and non-PTSD group were 1,277 and 3,557, respectively. The meta-analysis showed that the overall occurrence of PTSD after earthquakes among the elderly was 0.25; the occurrence in females was higher than that in males, and the occurrence in the same province indicated little difference (Wenchuan city 0.25 and Ya'an city 0.24).

CONCLUSIONS

After earthquakes, the occurrence of PTSD is higher among the elderly than among other age groups, and higher among the females than among the males, while there is little difference among different areas within the same province. This indicated that prioritized specific psychological interventions should be provided to the aged and the females.
