Identifying High-Risk Subgroups of College Students with Non-Suicidal Self-Injury: A Latent Profile Analysis and Two-Years Follow-up Study.

Non-Suicidal Self-Injury (NSSI) is associated with a heightened overall risk of future psychopathological problems. However, elucidating specific characteristics that determine an increased risk for certain individuals remains an area requiring further exploration. This study aimed to identify latent subgroups in a sample of college students with NSSI. Additionally, it sought to explore the differential associations of these subgroups with their psychopathological status (e.g., borderline symptoms and suicidal tendencies) both at baseline and after two years. The sample comprised 259 participants (89% females, Mage = 20.39, SD = 1.90) who reported engaging in NSSI in the last year. Three latent groups were found. The group exhibiting severe NSSI-features, high emotion dysregulation, and low perceived social support was the profile with high-risk of psychopathology both at baseline and follow-up. The findings enhance our understanding of the complex association between NSSI and future mental health issues, aiding in the early identification of at-risk individuals.

Psychotropic medication use among adolescents participating in three randomized trials of DBT.

BACKGROUND: Frequently presenting with symptoms of mood or anxiety disorders, substance abuse or borderline personality disorder, suicidal and self-harming adolescents often are prescribed psychotropic medication. Though such treatment may be warranted, recurrent suicidal and self-harming behaviour is often linked to emotion dysregulation where pharmacological treatment has weak empirical support. There is a need for more clinical research into the frequency, type and rationale for pharmacological treatment in this group. In this secondary analysis of three randomized clinical trials of dialectical behaviour therapy for adolescents, we report on psychotropic medication use in the respective samples at the time of recruitment, compare use of psychotropic medication across trials and describe sample characteristics that may be associated with possible differences in psychotropic medication. FINDINGS: Trials were conducted in Norway, the US and Spain (labelled the Oslo, US and Barcelona samples). At baseline, 86% of the Barcelona sample, 67% of the US sample and 12% of the Oslo sample were taking at least one psychotropic medication with antidepressants as the most frequent, followed by antipsychotics (72%, 22% and 1.3% respectively) and mood stabilizers (14.2%, 16.2% and 0%). In the Oslo sample there was a significant association between receiving a diagnosis of major depression and the likelihood of receiving antidepressants, but no such association was found in the Barcelona and US samples. The overall 7-8 times higher proportion of participants in the US and Barcelona samples treated with psychotropic medication could only partially be explained by differences between the samples in diagnostic profiles, symptom severity or level of dysfunction. CONCLUSIONS: Highly prevalent in use among suicidal and self-harming adolescents with borderline features, psychotropic medication was still very unevenly prescribed across trials, differences not explained by differences in sample characteristics suggesting that current treatment practices are not fully empirically supported. We call for continued medical education and increased availability of evidence-based psychosocial interventions.

Complex post-traumatic stress disorder (CPTSD) of ICD-11 in youths with childhood maltreatment: Associations with age of exposure and clinical outcomes.

BACKGROUND: Exposure to childhood maltreatment (CM) increases the risk of psychiatric morbidity in youths. The new Complex Post-Traumatic Stress Disorder (CPTSD) diagnosis captures the heterogeneity and complexity of clinical outcomes observed in youths exposed to CM. This study explores CPTSD symptomatology and its association with clinical outcomes, considering the impact of CM subtypes and age of exposure. METHODS: Exposure to CM and clinical outcomes were evaluated in 187 youths aged 7-17 (116 with psychiatric disorder; 71 healthy controls) following the Tools for Assessing the Severity of Situations in which Children are Vulnerable (TASSCV) structured interview criteria. CPTSD symptomatology was explored by confirmatory factor analysis, considering four subdomains: post-traumatic stress symptoms, emotion dysregulation, negative self-concept and interpersonal problems. RESULTS: Youths exposed to CM (with or without psychiatric disorders) showed greater internalizing, externalizing and other symptomatology, worse premorbid adjustment and poorer overall functioning. Youth with psychiatric disorder and exposed to CM reported more CPTSD symptomatology, psychiatric comorbidity and polypharmacy and earlier onset of cannabis use. Different subtypes of CM and the developmental stage of exposure differentially impact CPTSD subdomains. LIMITATIONS: Small percentage of resilient youths was studied. It was not possible to explore specific interactions between diagnostic categories and CM. Direct inference cannot be assumed. CONCLUSIONS: Gathering information on type and age of exposure to CM is clinically useful to understand the complexity of psychiatric symptoms observed in youths. Inclusion of the CPTSD diagnosis should increase the implementation of early specific interventions, improving youths' functioning and reducing the severity of clinical outcomes.

Los trastornos depresivos de la infancia y la adolescencia. Principales signos de alerta. Orientación para el tratamiento / Depressive disorders of childhood and adolescence. Main warning signs. Guidance for treatment

La depresión ha dejado de ser una enfermedad solo de adultos para presentarse cada vez más frecuentemente en niños y adolescentes, muy especialmente en la última década. Este diagnóstico puede llegar a ser un problema severo y de larga duración, que puede interferir en todos los aspectos del desarrollo del menor, su familia y su comunidad. El presente trabajo consiste en una revisión bibliográfica y actualizada sobre la depresión infanto-juvenil para facilitar su detección precoz desde los servicios de Pediatría en Atención Primaria y su derivación para el tratamiento precoz en los equipos de salud mental infanto-juvenil. Primero, presentamos los factores de vulnerabilidad y los factores de protección; luego, los síntomas y criterios diagnósticos para cada etapa del desarrollo, así como herramientas para el diagnóstico diferencial. Por último, se revisan brevemente los tratamientos basados en la evidencia disponibles y cómo intervenir en cada nivel de gravedad (AU)

Depression has ceased to be an illness only for adults, to appear more and more frequently in children and adolescents, especially in the last decade. This diagnosis can become a severe and long-lasting problem, which can interfere in all aspects of the development of the child, his family, and his community. The present work consists of a bibliographic and updated review on child and adolescent depression to facilitate the early detection at the pediatric primary services, and early derivation for treatment at the child and adolescent mental health services. First, we present the risk factors and protective factors that may signal populations-at-risk; then, the main symptoms and the diagnostic criteria for each stage of development, as well as tools for differential diagnosis. Finally, we briefly review the evidence-based treatments at each level of severity. (AU)

Psychological impact during COVID-19 lockdown in children and adolescents with previous mental health disorders.

OBJECTIVE: During the COVID-19 pandemic, authorities confined adults, adolescents and children to their homes. Recent articles warn of possible long-term consequences on mental health, especially for those who suffer from underlying psychiatric conditions and for vulnerable sections of the population. The present study explores the psychological impact of the COVID-19 quarantine on outpatients at the Centre of Child and Adolescent Mental Health (CAMHS), which is based in Barcelona. METHODS: A total of 441 caregivers answered an online ad-hoc survey on their sociodemographic and economic situation, perceived stress, and clinical changes and coping strategies observed in their children during lockdown. The Chi-square test was used to compare the response percentages for each behaviour or symptom between age, gender and diagnostic groups. Variance and post-hoc test were also analyzed, as was the Pearson correlation. RESULTS: The use of electronic devices has significantly increased. There has also been an increase in symptoms such as attentional problems, fatigue and irritability, among others. Differences were found between age and gender groups. The diagnostic groups most affected by confinement were Autism Spectrum Disorders and Conduct Disorders. The survey also discovered a relationship between the loss of family income, parental stress and increased symptoms in children. CONCLUSION: Confinement has increased externalizing symptoms and behaviours as well as COVID-19 related concerns, somatic problems and anxieties. It is important to observe the fluctuation of symptoms and how young people adapt to the pandemic in order to reach a better understanding of the situation and devise new strategies to reduce the psychological impact of the pandemic.

The Benefits of Dog-Assisted Therapy as Complementary Treatment in a Children's Mental Health Day Hospital.

Dog-assisted therapy (DAT) has shown benefits in people with mental health disorders. A child psychiatric day hospital would be a suitable setting to implement DAT and evaluate the benefits in a pediatric population. METHODS: Mixed methods research in a naturalistic setting was considered in this pre-post quantitative study including 23 children under 13 treated in a day hospital over 2 years. Quantitative analysis included the number of emotional and behavioral outbursts and attendance rate and self-control and social impairment questionnaires completed by family members and therapists. In the qualitative study, the experiences of 12 mental health professionals involved in DAT were documented through semi-structured interviews. RESULTS: On DAT days, there were fewer emotional and behavioral outbursts and higher attendance. Significant differences were obtained between pre- and post-test scores on the SCRS and the SRS-2 completed by the therapists, while no significant differences were obtained on the questionnaires completed by the parents. Observations based on the qualitative study were as follows: (1) DAT improves emotional self-regulation; (2) DAT could facilitate the work of therapists in day hospitals; (3) health professionals displayed uncertainty due to a lack of familiarity with DAT. CONCLUSIONS: DAT improved emotional self-regulation, attendance rate and self-control and social response in children with mental disorders attending a day hospital.

Borderline personality traits mediate the relationship between low perceived social support and non-suicidal self-injury in a clinical sample of adolescents.

BACKGROUND: Non-suicidal self-injury (NSSI) is a serious public health concern among adolescents, especially in clinical settings. Social support plays a critical role in the onset and maintenance of NSSI in adolescence. NSSI is closely associated with borderline personality disorder (BPD), yet no previous work has analyzed the mediating role of borderline traits in the relationship between perceived social support (PSS) and NSSI. This study aimed to address this gap. METHODS: Participants were 228 adolescent patients (12 to 18 years old), who completed a clinical interview and self-report measures of BPD-traits, current psychological distress, emotion dysregulation and PSS. They were grouped based on the presence (vs. absence) of NSSI. Univariate and multivariate logistic regression analyses were used to identify risk factors of NSSI, and a mediation analysis was conducted to examine the intermediary role of borderline traits in the relationship between PSS and NSSI. RESULTS: NSSI was highly prevalent in our sample (58%) and was associated with higher clinical severity. Low PSS predicted NSSI in univariate, but not multivariate regression. Mediation analyses showed that borderline traits fully accounted for the relationship between low PSS and NSSI, even when controlling for current psychological distress and gender. LIMITATIONS: Cross-sectional design through self-report assessment. CONCLUSIONS: Findings suggest that adolescents with low PSS are especially vulnerable for developing NSSI due to elevated BPD traits. In clinical settings, interventions aimed to reduce borderline symptoms may be a promising treatment option for adolescents with NSSI and low PSS.

Risk of Suicidal Behavior in Children and Adolescents Exposed to Maltreatment: The Mediating Role of Borderline Personality Traits and Recent Stressful Life Events.

Childhood maltreatment (CM) is associated with increased non-suicidal self-injury (NSSI) and suicidal behavior (SB), independently of demographic and mental health conditions. Self-Trauma Theory and Linehan's Biopsychosocial Model might explain the emergence of Borderline Personality Disorder (BPD) symptoms as mediators of the association between CM and the risk of SB. However, little is known regarding such relationships when the exposure is recent for young persons. Here, we study 187 youths aged 7-17, with or without mental disorders. We explore CM experiences (considering the severity and frequency of different forms of neglect and abuse), recent stressful life events (SLEs), some BPD traits (emotion dysregulation, intense anger and impulsivity), and the risk of SB (including NSSI, suicide threat, suicide ideation, suicide plan and suicide attempt). We study the direct and mediating relationships between these variables via a structural equation analysis using the statistical software package EQS. Our findings suggest that youths exposed to more severe/frequent CM have more prominent BPD traits, and are more likely to have experienced recent SLEs. In turn, BPD traits increase the risk of SLEs. However, only emotion dysregulation and recent SLEs were found to be correlated with SB. Therefore, targeted interventions on emotion dysregulation are necessary to prevent NSSI or SB in children and adolescents exposed to CM, as is the minimization of further SLEs.

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.

Adapted Dialectical Behavior Therapy for Adolescents with a High Risk of Suicide in a Community Clinic: A Pragmatic Randomized Controlled Trial.

OBJECTIVE: This study is a pragmatic randomized controlled trial, which compares the effectiveness of an adapted form of Dialectical Behavior Therapy for Adolescents (DBT-A) and treatment as usual plus group sessions (TAU + GS) to reduce suicidal risk for adolescents in a community health mental clinic. METHOD: Thirty-five adolescents from a community outpatient clinic, with repetitive NSSI alone or with SA over the last 12 months and with current high suicide risk as assessed by the Columbia-Suicide Severity Rating Scale (C-SSRS), were enrolled. Participants were randomly assigned to undergo either DBT-A (n = 18) or TAU + GT (n = 17) treatments over a 16-week period. Primary outcomes were the difference between NSSI and SA recorded during the first 4 weeks and the final 4 weeks of treatment. Secondary outcomes included changes in Children's Global Assessment Scale (C-GAS), Suicidal Ideation Questionnaire (SIQ-JR), and Beck Depression Inventory-II (BDI-II). RESULTS: Dialectical Behavior Therapy for Adolescents was more effective than TAU + GS at reducing NSSI, use of antipsychotics, and improving C-GAS. No SAs were reported in the two groups at the end of the treatment. Both treatments were equally effective in decreasing SIQ-JR and BDI-II scores. CONCLUSIONS: These findings support the feasibility and effectiveness of DBT-A for adolescents at high risk of suicide in community settings.

Fronto-Limbic Connectivity as a Predictor of Improvement in Nonsuicidal Self-Injury in Adolescents Following Psychotherapy.

Objectives: Key neurobiological factors contribute to vulnerability to nonsuicidal self-injury (NSSI) among adolescents and how they respond to treatment targeted to reduce such behaviors. This study aims to examine differences in intrinsic functional connectivity between adolescents with NSSI and healthy controls (HCs) and to identify baseline connectivity markers that predict improvements in NSSI after psychotherapy. Methods: Adolescents aged 12-17 (n = 24) with repetitive NSSI along with demographically similar HCs (n = 16) underwent resting-state functional MRI scanning after which patients received up to 4 months of psychological treatment. A seed-based approach was used to examine baseline between-group differences in intrinsic functional connectivity of the amygdala and the medial prefrontal cortex (mPFC). Further analyses examined the associations between intrinsic functional connectivity at baseline and improvement in NSSI after psychological treatment. Results: Compared with HCs, adolescents with NSSI showed significantly reduced connectivity between the amygdala and the anterior cingulate cortex, subcallosal cortex, and paracingulate gyrus, as well as between the amygdala and a cluster encompassing the right planum temporale and right insula. Adolescents with NSSI, compared with HCs, also showed reduced connectivity between the mPFC and two clusters: one located in the precentral and postcentral gyri and another in the left insula. After treatment, 50% of patients reported fewer NSSI episodes compared to baseline, which was considered as improvement. Stronger negative amygdala-prefrontal connectivity was associated with greater posttreatment improvement in NSSI. Conclusions: Adolescents with NSSI may have aberrant amygdala and mPFC connectivity compared with HCs. Furthermore, stronger baseline negative amygdala-prefrontal connectivity may predict greater improvement in NSSI after psychological intervention. Given that no prior study has used resting-state functional connectivity to predict response to psychological treatment in adolescents with NSSI, replication of these findings is needed.

An exploratory study comparing psychological profiles and its congruence with clinical performance among patients with functional or motility digestive disorders.

Functional gastrointestinal disorders have been related with different psychological conditions. On the contrary, the role of psychological factors within gastrointestinal motor disorders remains unclear. The objective of this study was to explore the differences and congruence with clinical performance of the psychological profile and subjective functionality among patients diagnosed with functional gastrointestinal disorders and gastrointestinal motor disorders. Using a double-blind design, 56 inpatients from a Gastroenterology Department were included in the study. No major differences were detected between the two groups. However, clinical performance was coherent with subjective physical functioning only among patients diagnosed with gastrointestinal motor disorders. These results may provide useful information for gastroenterologists dealing with patients' complaints not consistent with their clinical profile.

Neuropsychological impairment in female patients with chronic fatigue syndrome: a preliminary study.

This study examines neuropsychological impairments associated with chronic fatigue syndrome (CFS) and explores their association with related clinical factors. Sixty-eight women with CFS were assessed with a neuropsychological battery. Raw scores were adjusted for age and gender and were converted to T scores according to normative data extracted from a local sample of 250 healthy subjects. Neuropsychological dysfunction was calculated using summary impairment indexes (proportion of test scores outside normal limits-T score <40-for each cognitive domain). Finally, a linear regression was calculated to identify predictors of cognitive deficit, including intrinsic factors of the disease (level of fatigue and length of illness) and extrinsic factors (emotional factors, age, and education). Approximately 50% of scores showed impairment in attention and motor functioning, and nearly 40% showed impairment in speed information processing and executive functioning. Fatigue predicted attention and executive functioning impairment, and emotional factors predicted verbal memory dysfunction. According to our findings, cognitive dysfunction in CFS could be explained by pathophysiological processes of the disease. One implication of this would be the need to identify homogeneous subgroups of patients with CFS by taking into account common factors, which, in turn, would help to identify more specific cognitive profiles, which could then serve to implement appropriate therapeutic measures accordingly.

Length of illness does not predict cognitive dysfunction in chronic fatigue syndrome.

Neuropsychological studies have shown cognitive impairment in chronic fatigue syndrome (CFS), particularly in information-processing speed. The aim of this study was to examine the evolution of cognitive impairment in CFS. The evolution is one of the most disabling aspects of the CFS, and it has received little attention in the literature. Fifty-six women with CFS were assessed with neuropsychological tests. Patients were divided into three groups based on the duration of the disease. There were no differences between groups in terms of cognitive function. The cognitive impairment in CFS was not found to be more severe with longer disease duration. These data suggest that there is no progressive cognitive impairment in patients with CFS. Therefore, the cognitive deficits in CFS should be treated with cognitive rehabilitation programs focused on improving emotional distress associated to the illness and on promoting functional abilities.

El rol de la depresión en el déficit cognitivo del paciente con síndrome de fatiga crónica / The role of depression in cognitive inpairment in patients with chronic fatigue syndrome

Fundamento y objetivo: Analizar el rol de la depresión en el déficit cognitivo del paciente con síndrome de fatiga crónica (SFC). Pacientes y método: Un total de 57 mujeres con diagnóstico de SFC fueron evaluadas mediante tests neuropsicológicos que incluían medidas de atención (CalCap, Control Mental del WMS-III, PASAT, dígitos directos e inversos del WAIS-III y symbol digit modalities test [SDMT]) funciones ejecutivas (test Stroop, Trail Making Test [TMT A y B], FAS y Torre de Londres), memoria (Test de Aprendizaje Auditivo-Verbal [TAAVL] y Test de la Figura Compleja de Rey [FCR]) y velocidad psicomotora (Grooved Pegboard). Las puntuaciones directas fueron ajustadas de acuerdo a datos normativos y transformadas a puntuaciones típicas. La muestra fue dividida en dos grupos en función de la presencia o no de depresión, evaluada mediante entrevista clínica y la administración de la Escala Hospitalaria de Ansiedad y Depresión (HAD). Las puntuaciones de los test neuropsicológicos fueron comparadas entre ambos grupos de pacientes.Resultados: Los pacientes con SFC presentaron déficit cognitivo en funciones atencionales y ejecutivas, independientemente de la presencia de depresión. No se observaron diferencias significativas en funciones cognitivas entre los dos grupos de pacientes.Conclusiones: Estos datos sugieren que el déficit cognitivo que presentan los pacientes con SFC no es secundario a la depresión. Se debería tener en cuenta este resultado en la implementación de un programa terapéutico en estos enfermos (AU)

Influencia de la reserva cognitiva en el rendimiento neuropsicológico de los pacientes con epilepsia / Influence of cognitive reserve on neuropsychological performance in epileptic patients

Fundamento y objetivo: Determinar el efecto de la reserva cognitiva (RC) en el funcionamiento cognitivo de los pacientes con epilepsia del lóbulo temporal (ELT). Pacientes y método: Se evaluó con una batería neuropsicológica que incluía medidas de memoria, atención, habilidades visuoconstructivas y lenguaje a 28 pacientes con ELT admitidos en un programa de cirugía de la epilepsia. Las puntuaciones directas, ajustadas según los baremos correspondientes, se transformaron en puntuaciones normalizadas (puntuaciones z). La RC se determinó a partir del cociente intelectual premórbido, el nivel educativo y el nivel ocupacional. Resultados: No se observaron diferencias significativas entre los grupos de alta y baja RC en las variables sociodemográficas y clínicas relevantes. Los pacientes con baja RC obtuvieron un rendimiento significativamente menor que los pacientes con alta RC en los test de memoria verbal (p<0,039), atención (p<0,001), visuoconstrucción (p<0,019) y fluidez fonética (p<0,003) y semántica (p<0,005). Conclusiones: Los pacientes epilépticos con baja RC muestran mayor morbilidad cognitiva que los pacientes con alta RC. Estos hallazgos indican que una mayor RC puede reducir la vulnerabilidad o retrasar la manifestación clínica del deterioro cognitivo asociado a la ELT (AU)

Background and objective: Our goal was to determine the influence of the cognitive reserve (CR) on the neuropsychological performance of patients with temporal lobe epilepsy (TLE). Patients and method: Twenty-eight patients with TLE from a program of epilepsy surgery were assessed with a neuropsychological battery that included standard clinical measures of memory, attention, visual-construction skills and language. Raw scores adjusted according normative data were transformed to z scores. CR scores were based on a combination of educational level, occupational attainment and estimated premorbid intelligence. Results: There were no significance differences in socio-demographic and clinical features between the 2 groups. Epileptic patients with low CR showed significantly lower scores than patients with high CR, with regard to measures of verbal memory (p<0.039), attention (p<0.001), visual-construction skills (p<0.019), and phonetic (p<0.003) and semantic (p<0.005) fluency. Conclusions: Epileptic patients with low CR showed greater neuropsychological morbidity than patients with high CR. These findings suggest that higher CR may decrease vulnerability or delay the clinical manifestation related to cognitive deficits following TLE (AU)
