Are neurocognitive factors associated with repetition of self-harm? A systematic review

Self-disgust mediates the effect of problematic mobile social media use on non-suicidal self-injury in adolescents: A latent growth curve analysis

OBJECTIVE

Previous research linked problematic mobile social media use to non-suicidal self-injury (NSSI). However, little research explored the underlying mechanism. Drawing on the social displacement hypothesis, which suggests that excessive social media use may disrupt offline social interactions, leading to negative emotional experiences, the study employs a longitudinal design to explore the relationship between problematic mobile social media use and NSSI, with a specific emphasis on the mediating role of self-disgust.

METHODS

A total of 1,684 Chinese adolescents (52.3% females; Mage = 14.59 years, SDage = 1.27) completed self-report questionnaires regarding problematic mobile social media use, self-disgust, and NSSI. The assessment was conducted in three waves, 6 months apart.

RESULTS

Using latent growth curve and structural equation modeling, our study observed a consistent linear decline in NSSI levels over time. Higher initial NSSI levels correlated with a slower reduction. Problematic mobile social media use positively influenced the initial level of NSSI. Additionally, self-disgust played a mediating role in the relationship between problematic mobile social media use and NSSI.

CONCLUSIONS

The study underscores the importance of understanding the emotional experiences behind social media use, beyond mere usage duration. By revealing the mediating role of self-disgust, it provides new insights into the complex interplay between problematic mobile social media use and adolescent NSSI.

Neuropsychological functioning and suicidal behaviours in patients with first-episode psychosis: A systematic review

INTRODUCTION

Suicidal behaviour is particularly frequent in patients with psychosis. Therefore, prevention is a key objective of mental health policies. The aim of the current work is to systematically review the association between neurocognitive functioning and suicidal behaviour in patients with first-episode psychosis (FEP).

MATERIAL AND METHODS

Of the 3051 studies reviewed, only 7 met the inclusion criteria. Documents in English from their earliest date of coverage until January 2022 were searched for in the following databases: PubMed, Science Direct, Web of Science, Cochrane Library, PsycINFO (ProQuest), and Springerlink. We used the PICO strategy to collect and categorize the data from each selected manuscript.

RESULTS

Overall, the results showed that the risk of suicidal behaviour is higher for FEP patients in the presence of a number of factors: poorer general neuropsychological functioning (except for working memory), poorer social cognition, more depressive symptoms, longer duration of untreated psychosis, higher awareness of the illness, poorer premorbid adjustment, and more frequent cannabis use.

DISCUSSION

Comprehensive general neuropsychology and assessment of social cognition, together with routine clinical record keeping, may help to identify FEP patients at a greater risk of attempting suicide.

Longitudinal associations of the duration of mobile phone use with suicidal behavior in adolescents: The mediating role of depressive symptoms

BACKGROUND

Prolonged mobile phone use has been demonstrated to be associated with mental health problems and suicidal behavior in adolescents. This study examined the mediating role of depressive symptoms in the association between duration of mobile phone use (DMPU) and suicidal behavior in adolescents.

METHODS

A total of 6,923 participants from the Shandong Adolescent Behavior & Health Cohort (SABHC) were included in the analysis. Participants completed a self-administered questionnaire to assess DMPU on weekdays and weekends, mental disorders, insomnia symptoms, depressive symptoms, suicidal behavior (thought, plan, or attempt), and family demographics in November-December 2015. One year later, a follow-up survey was conducted to ask participants to report their depressive symptoms and suicidal behavior. Path analyses with logistic regressions were performed to examine the mediating role of depressive symptoms in the DMPU-suicidal behavior link.

RESULTS

Of the sample, mean age was 14.58 (SD = 1.45) and 3,455 (49.9 %) were female at baseline. 12.12 % of participants reported having ever suicidal behavior during the past 12 months at baseline, and 10.63 % reported having ever suicidal behavior during 1-year follow-up. Path analyses showed that the depressive symptoms played a partial mediating role in the association of DMPU on weekdays and weekends with subsequent suicidal behavior. After controlling for covariates, depressive symptoms accounted for 33.6 % and 58.6 % of the total effect of DMPU on weekdays and weekends on suicidal behavior, respectively.

LIMITATION

All variables were measured based on self-report.

CONCLUSIONS

The link between DMPU and suicidal behavior was partially mediated by depressive symptoms. Prolonged mobile phone use and depressive symptoms should be assessed and intervened to prevent suicidal behavior in adolescents.

Building a neurocognitive profile of suicidal risk in severe mental disorders

BACKGROUND

Research on the influence of neurocognitive factors on suicide risk, regardless of the diagnosis, is inconsistent. Recently, suicide risk studies propose applying a trans-diagnostic framework in line with the launch of the Research Domain Criteria Cognitive Systems model. In the present study, we highlight the extent of cognitive impairment using a standardized battery in a psychiatric sample stratified for different degrees of suicidal risk. We also differentiate in our sample various neurocognitive profiles associated with different levels of risk.

MATERIALS AND METHODS

We divided a sample of 106 subjects into three groups stratified by suicide risk level: Suicide Attempt (SA), Suicidal Ideation (SI), Patient Controls (PC) and Healthy Controls (HC). We conducted a multivariate Analysis of Variance (MANOVA) for each cognitive domain measured through the standardized battery MATRICS Consensus Cognitive Battery (MCCB).

RESULTS

We found that the group of patients performed worse than the group of healthy controls on most domains; social cognition was impaired in the suicide risk groups compared both to HC and PC. Patients in the SA group performed worse than those in the SI group.

CONCLUSION

Social cognition impairment may play a crucial role in suicidality among individuals diagnosed with serious mental illness as it is involved in both SI and SA; noteworthy, it is more compromised in the SA group fitting as a marker of risk severity.

Exploring working memory, self-criticism, and rumination as factors related to self-harm

The prevalence of self-harm and the relative emotional influences are well understood, but certain cognitive factors such as working memory, rumination, and self-criticism are not fully explored. The aim of the current study is to examine specific aspects of cognition to explore their influence on self-harming behaviors. Participants included 101 undergraduates from a British University. Factors were measured using the Centre for Epidemiological Studies Depression Scale, the Depressive Experiences Questionnaire, Ruminative Response Scale, and the Automated Working Memory Assessment. Findings indicated a greater incidence of self-harming behaviors among those who demonstrated higher depressive symptoms, but depression scores were not significantly related to self-harm. Additionally, a binary logistic regression indicated that self-criticism was associated with the presence of self-harming behavior, and a Classification and Regression Trees found that the single strongest predictor of self-harming behavior was a belief that love needs to be continually earned from others. Incorporating treatments that reduce self-criticism, such as improving self-compassion with Compassionate Mind Training, may address underlying mechanisms that trigger self-harm behavior. Keywords: rumination, depression, self-criticism, working memory, self-harm.

Decision-making in suicidal behavior: A systematic review and meta-analysis

Impaired decision-making (DM) is well-known in suicidal behavior (SB). We aimed to review the evidence on DM and its mediating factors in SB and perform a meta-analysis on DM assessed using the Iowa Gambling Task (IGT). We conducted a search on databases of papers published on DM and SB up to 2020: 46 studies were included in the systematic review, and 18 in the meta-analysis. For meta-analysis, we compared DM performance between suicide attempters (SAs) and patients (PCs) or healthy controls (HCs). The systematic review showed that SAs have greater difficulties in all DM domains. The meta-analysis found worse IGT performance among SAs in comparison with PCs and HCs. A meta-regression did not find differences for age, gender, psychiatric disorder, and clinical status. Our findings indicate that SAs exhibited deficits in DM under conditions of risk though not ambiguity. Worse DM was independent of age, gender, psychiatric disorder, and suggested that DM impairment could be considered a cognitive trait of suicidal vulnerability, a risk factor and an attribute of SAs.

Neurocognitive Functioning in Adolescents at Risk for Suicidal Behaviors

Today, little is still known about the neurocognitive functioning of the individual at risk for suicide in a relevant developmental stage like adolescence. Thus, the main goal of the present work was to analyze the neurocognitive performance of adolescents at high risk for suicide. A total of 1509 adolescents from a stratified random cluster sampling were selected. Adolescents at risk for suicidal behaviors included 83 participants. A comparison group of 83 participants matched by age and gender was also randomly selected from the sample. The Paykel Suicide Scale (PSS) and the University of Pennsylvania Computerized Neurocognitive Battery for children (included 14 tasks assessing five neurobehavioral domains: executive functions, episodic memory, complex cognition, social cognition, and sensorimotor speed) were used. Adolescents at risk for suicide revealed statistically significant impairments across different neurocognitive domains including complex cognition, episodic memory and social cognition. No significant differences were found for Sensorimotor and Executive Function domains. Results found in the present study contribute relevant information about the nature of the neurocognitive impairments associated with suicide and add information in order to deeper comprehend the tentative etiology of suicide thoughts and attempts in adolescents with the aim to establish preventive treatments.

Visual memory improvement in adolescents at high risk for suicide who are receiving psychotherapy at a community clinic

The current study aims to: 1) investigate cognitive differences among adolescents at risk for suicide versus healthy controls (HC) and 2) identify cognitive changes associated with response to psychotherapy among adolescents at high risk for suicide. Thirty-five adolescents at high risk for suicide (HR), and 14 HC adolescents were recruited. Clinical and cognitive assessments were conducted in both groups at baseline and 16 weeks later (after the patients completed psychotherapy). HR and HC adolescents were compared at baseline and at completion of the study. We also conducted further analysis by separating into two groups the HR adolescents who responded to psychotherapy (n=17) and those who did not (n=11). At baseline, the HR group had significantly lower performance on verbal memory and processing speed than the HC group. At week 16, HR adolescents performed as well as HC adolescents in all cognitive domains. Among patients, better performance on visual memory was observed in those who responded to psychotherapy compared to those who did not. We concluded that lower performance on verbal memory and processing speed may be associated with a high risk for suicide among adolescents. Improvement in visual memory might be related to a lower risk for suicide in adolescents.

Digital media use and subsequent self-harm during a 1-year follow-up of Chinese adolescents

BACKGROUND

Excessive digital media use is prevalent and has a negative impact on sleep, daytime functioning, and mental health in adolescents. We examined the prospective associations between digital media use and subsequent suicidal and non-suicidal self-harm.

METHODS

Shandong Adolescent Behavior & Health Cohort (SABHC) is a longitudinal study of adolescent behavior and health in Shandong, China. Participants included for the analysis were 7,072 SABHC adolescents who were initially assessed in 2015 and were reassessed in 2016. A self-administered structured questionnaire was used to measure digital media use (i.e., television watching, internet use, and mobile phone use) on weekdays and at the weekend, mental health, and self-harm.

RESULTS

Multivariable logistic regression analyses showed that daily internet use ≥2 h on weekdays (odd ratio (OR) = 1.86, 95% confidence interval(CI) = 1.25-2.76) and ≥3 h at the weekend (OR = 1.46, 95%CI = 1.06-2.00) and daily mobile phone use 2-3 h (OR = 1.46, 95%CI = 1.02-2.10) and ≥4 h (OR = 1.74, 95%CI = 1.20-2.51) at the weekend were significantly associated with increased risk of recurrent self-harm. Daily internet use ≥ 2 h on weekdays (OR = 1.81, 95%CI = 1.20-2.74) and ≥3 h at the weekend (OR = 1.55, 95%CI = 1.12-2.15), daily mobile phone use 1-2 h on weekdays (OR = 1.47, 95%CI = 1.02-2.12) and 2-3 h (OR = 1.49, 95%CI = 1.01-2.19) and ≥4 h (OR = 1.93, 95%CI = 1.31-2.85) at the weekend were significantly associated with increased risk of recurrent non-suicidal self-injury. Daily internet use 1-2 h on weekdays and 2-3 h at the weekend were significantly associated with increased risk of new suicide attempt (OR =  1.80, 95%CI =  1.07- 3.03) and recurrent suicide attempt (OR =  6.26, 95%CI = 1.31-29.88), respectively.

LIMITATIONS

All data were self-reported.

CONCLUSIONS

Excessive use of internet or mobile phone appears to be a significant risk factor of self-harm, suggesting that limiting adolescent use of internet and mobile phone may be beneficial to reduce risk of self-harm.

New Evidences about Subjective Well-Being in Adolescence and Its Links with Neurocognitive Performance

The main purpose of the present work was to study the neurocognitive endophenotypes of adolescents at risk for low personal wellbeing. The sample included a total of 1588 adolescents from stratified random cluster sampling; derived from this sample, a group of high-risk (n = 84) and a control group (n = 84) were selected. The personal well-being index–school children (PWI–SC), the University of Pennsylvania computerized neuropsychological test battery for children (included 14 tasks assessing five neurobehavioral domains: executive functions, episodic memory, complex cognition, social cognition and sensorimotor speed), and the strengths and difficulties questionnaire (SDQ) were used. Adolescents with low personal wellbeing showed statistically significant impairments across the different neurocognitive domains. In particular, adolescents at risk showed lower accuracy scores on executive function and complex cognition and lower speed scores on episodic memory, complex cognition and social cognition scores. The results of the present study contribute relevant information about the nature of neurocognitive impairments associated with subjective wellbeing and allow implementing preventive treatments.

Attempting to disentangle the relationship between impulsivity and longitudinal self-harm: Epidemiological analysis of UK household survey data

BACKGROUND

Impulsivity may be an important risk factor in terms of future self-harm. However, the extent of this, whether it may relate to self-harm that is new in onset and/or repetition of self-harm, and the detail of any interaction with mood instability (MI) and childhood sexual abuse (CSA) requires detailed examination.

AIMS

We used the 2000 Adult Psychiatry Morbidity Survey and an 18-month follow-up data to test hypotheses relating to the role of impulsivity, CSA and MI in the inception and persistence of self-harm.

METHODS

We assessed associations of impulsivity with (1) suicidal self-harm (SSH) and (2) non-SSH (NSSH) at baseline and follow-up, controlling for confounders including MI. Finally, we tested whether impulsivity mediated the relationship between CSA and self-harm.

RESULTS

A total of 8,580 respondents were assessed at baseline and 2,406 at follow-up as planned. Impulsivity significantly predicted emergence of new NSSH at 18-month follow-up even after adjustment for MI and other confounders. Impulsivity did not significantly predict repetition of NSSH, or repetition or new inception of SSH, even before inclusion of MI in the model. However, the absolute numbers involved were small. Cross-sectionally, impulsivity was a stronger mediator of the link between CSA and SSH (13.1%) than that between CSA and NSSH (4.8%).

CONCLUSION

Impulsivity may increase the risk of future development of NSSH independently of MI, which is clinically important for risk assessment. The involvement of impulsivity in the repetition of self-harm generally appears less certain. However, impulsivity may have a role in SSH in the context of previous CSA.

Neurocognitive impairment and suicide risk among prison inmates

BACKGROUND

Worldwide, prisoners are at high risk of suicide. Reducing the number of suicides in jails and prisons is an international priority. Several risk factors for suicide attempts, such as historical, prison-related, psychosocial and clinical factors, have been found in prisoners. We assessed whether demographic, conviction-related and neuro-behavioral variables might be associated with current suicide risk and lifetime suicide attempts in two large central Italy prisons.

METHODS

On a preliminary sample of 254 detainees within an ongoing project, we assessed whether demographic, conviction-related, psychiatric, cognitive variables and illness comorbidity might be associated with current suicide risk and lifetime suicide attempts in two large central Italy prisons. Psychiatric disorders and suicide risk was evaluated using the Mini International Neuropsychiatric Interview. We also have identified the detainees with clear-cut previous suicide attempts. The cognitive function was assessed with a brief neuropsychological battery including trail making A, trail making B, Digit Span, and Symbol Digit test. Impulsivity was assessed with the Barratt Impulsiveness Scale. Cumulative illness was evaluated with Charlson Comorbidity Index.

RESULTS

Impairment in global cognitive function was the strongest predictor of both high suicide risk and lifetime suicide attempts (both p < 0.001), independently of psychiatric disorders, psychopharmacological treatment, detention status, conviction time, substance use disorder, impulsivity, and illness comorbidity. Limitation LIMITATION: Cross-sectional study design and relatively small sample size.

CONCLUSION

Cognitive deficits may improve our understanding of the suicidal vulnerability and should be systematically included in the assessment of suicide risk, as potential predictors of suicidal acts and targets of preventive interventions.

Early maladaptive schemas of emotional deprivation, social isolation, shame and abandonment are related to a history of suicide attempts among patients with major depressive disorders

BACKGROUND

Patients with psychiatric disorders have an exceptionally high risk of completed or attempted suicide. This holds particularly true for patients with major depressive disorders. The aim of the present study was to explore whether patients with major depressive disorders (MDD) and a history of suicide attempts differed in their early maladaptive schemas from patients with MDD but without such a history or from healthy controls.

METHOD

Ninety participants took part in the study. Of these, 30 were patients with MDD who had made a recent suicide attempt; 30 were patients with MDD but no suicide attempts, and 30 were gender- and age-matched healthy controls. Participants completed questionnaires covering socio-demographic characteristics and the Young Schema Questionnaire (YSQ- RE2R) to assess early maladaptive schemas. Experts rated patients' MDD with the Montgomery-Asberg Depression Rating Scale.

RESULTS

Patients did not differ in experts' ratings of symptoms of depression. Compared to healthy controls, patients with MDD recorded higher scores on maladaptive schemas such as recognition seeking, negativity/pessimism, and insufficient self-control. Compared to patients without suicide attempts and healthy controls, those who had made a suicide attempt had higher scores on dimensions such as failure, mistrust, emotional inhibition, social isolation, and abandonment/instability.

CONCLUSION

Compared to healthy controls, patients with MDD had more pronounced maladaptive schemas, but this was more marked in patients with a history of suicide attempts. The results suggest that suicide attempts and poorer psychological functioning are related.
