Emotion dysregulation and mindfulness in non-suicidal self-injury.

This study examined the association between mindfulness and engagement in non-suicidal self-injury (ENSSI) and whether emotion dysregulation explains this association. A secondary objective was to explore the difference between participants who engaged in a suicide attempt and those who only engaged in non-suicidal self-injury. A sample of 201 psychiatric patients (62.7% female; age range: 18-71 years old) participated in the study. The path analysis indicated that trait mindfulness was negatively associated with all emotion dysregulation dimensions and that one of these dimensions, impulse control difficulty, was associated with higher ENSSI. Moreover, impulse control difficulty was associated with increased odds of having attempted suicide. These findings suggest that mindfulness is a relevant construct to ENSSI with and without a suicide attempt. Future studies should investigate mindfulness-based interventions for ENSSI and the role played by the capacity to control impulses when experiencing negative emotions.

¿Influye el trauma infantil en el reconocimiento de las emociones faciales independientemente del diagnóstico de trastorno mental grave? / Can childhood trauma influence facial emotion recognition independently from a diagnosis of severe mental disorder?

INTRODUCCIÓN: El reconocimiento de las expresiones faciales (REF) es un componente fundamental en la interacción social. Sabemos que dicho REF se encuentra alterado tanto en los pacientes con trastorno mental grave (TMG) como en los que padecen antecedentes de trauma infantil. MATERIAL Y MÉTODOS: Pretendemos analizar la posible relación entre la existencia de trauma en la infancia más allá de la presencia de un TMG, medido mediante la escala CTQ y el reconocimiento de las expresiones faciales, en una muestra con tres tipos de sujetos (n=321): controles sanos (n=179), pacientes con TLP (n=69) y primeros episodios psicóticos (n=73). Así mismo, se recogieron variables clínicas y datos sociodemográficos. Se analizó dicha relación mediante una técnica de regresión multivariante ajustando por el sexo, la edad, el CI, el consumo actual de tóxicos y el grupo al que pertenece el sujeto. RESULTADOS: El trauma sexual y/o físico en la infancia se relacionó de forma independiente de la existencia de TMG con un peor ratio de REF total, además de con una peor tasa de reconocimiento en las expresiones de felicidad. Además, los sujetos con antecedentes de trauma en la infancia atribuyeron con mayor frecuencia expresiones de enfado y miedo a las caras neutras y felices, independientemente de otras variables. CONCLUSIONES: La existencia de trauma en la infancia parece influir de manera independiente al TMG en la capacidad de los sujetos de reconocer expresiones faciales. Dado que el trauma es un factor prevenible y con un tratamiento específico, se debería prestar atención a la existencia de este antecedente en las poblaciones clínicas

INTRODUCTION: Facial emotion recognition (FER) is a fundamental component in social interaction. We know that FER is disturbed in patients with severe mental disorder (SMD), as well as those with a history of childhood trauma. MATERIAL AND METHODS: We intend to analyze the possible relationship between the existence of trauma in childhood irrespective of a SMD, measured by the CTQ scale and facial expression recognition, in a sample of three types of subjects (n=321): healthy controls (n=179), patients with BPD (n=69) and patients with a first psychotic episode (n=73). Likewise, clinical and socio-demographic data were collected. The relationship was analyzed by a technique of multivariate regression adjusting for sex, age, IQ, current consumption of drugs and group to which the subject belonged. RESULTS: Sexual and/or physical trauma in childhood related independently to the existence of SMD with a worse total FER ratio, as well as to a worse rate of recognition in expressions of happiness. Furthermore, the subjects with a history of childhood trauma attributed expressions of anger and fear more frequently to neutral and happy faces, irrespective of other variables. CONCLUSIONS: The existence of trauma in childhood seems to influence the ability of subjects to recognize facial expressions, irrespective of SMD. Trauma is a preventable factor with specific treatment; therefore, attention should be paid to the existence of this background in clinical populations

Affectively salient signal to random noise might be used to identify psychosis vulnerability in severe mental disorders.

BACKGROUND: Subclinical psychotic symptoms are present in the general population. Furthermore, they are quite common in diagnostic categories beyond psychosis, such as BPD patients. METHODS: We want to assess the differences between 3 groups: BPD (n = 68), FEP (n = 83) and controls (n = 203) in an experimental paradigm measuring the presence of speech illusions in white noise. The Positive and Negative Syndrome Scale was administered in the patient group, the Structured Interview for Schizotypy-Revised, and the Community Assessment of Psychic Experiences in the control and BPD group. The white noise task was also analysed within a signal detection theory (SDT) framework. Logistic regression analyses and the general linear models were used to analyse the adjusted differences between groups. RESULTS: Differences were more prevalent in signals that were perceived as affectively salient in patients groups (9.6% in FEP vs 5.9% in BPD and 1% in controls; OR: 10.7; 95%CI: 2.2-51.6, p = 0.003 in FEP; OR: 6.3; 95%CI: 1.1-35.0, p = 0.036 in BPD). Besides, we found a worse general performance and more false alarms in the task for FEP group using SDT framework. CONCLUSIONS: Experimental paradigms indexing the tendency to detect affectively salient signals in noise may be used to identify liability to psychosis in people with vulnerability. Its predictable value in other diagnostic categories and general population requires further research.

Relation between psychotic symptoms, parental care and childhood trauma in severe mental disorders.

A relation between different types of parental care, trauma in childhood and psychotic symptoms in adulthood has been proposed. The nature of this association is not clear and if it is more related to psychotic disorders per se or to a cluster of symptoms such as positive psychotic symptoms remains undefined. We have analysed the presence of childhood trauma using the CTQ scale and types of parental care using the PBI scale in three groups of subjects: borderline personality disorder patients (n=36), first psychotic episode patients (n=61) and healthy controls (n=173). Positive psychotic symptomatology was assessed with the CAPE scale. General linear models were used to study the relation between positive psychotic symptomatology and variables of interest. BPD patients had the highest rate of any kind of trauma, followed by FEP patients. We found a positive relationship between psychotic symptomatology and the existence of trauma in childhood in all groups. Moreover, an affectionless control rearing style was directly associated with the existence of trauma. Furthermore, subjects with trauma presented less probability of having an optimal parenting style in childhood. The relation between psychotic symptoms and trauma remained statistically significant after adjusting for other variables including parental rearing style. There seems to be a link between trauma in childhood and psychotic symptomatology across different populations independently of psychiatric diagnosis. Taking into account that there is an association between trauma and psychosis and that trauma is a modifiable factor, clinicians should pay special attention to these facts.

Data Gathering Bias: Trait Vulnerability to Psychotic Symptoms?

BACKGROUND: Jumping to conclusions (JTC) is associated with psychotic disorder and psychotic symptoms. If JTC represents a trait, the rate should be (i) increased in people with elevated levels of psychosis proneness such as individuals diagnosed with borderline personality disorder (BPD), and (ii) show a degree of stability over time. METHODS: The JTC rate was examined in 3 groups: patients with first episode psychosis (FEP), BPD patients and controls, using the Beads Task. PANSS, SIS-R and CAPE scales were used to assess positive psychotic symptoms. Four WAIS III subtests were used to assess IQ. RESULTS: A total of 61 FEP, 26 BPD and 150 controls were evaluated. 29 FEP were revaluated after one year. 44% of FEP (OR = 8.4, 95% CI: 3.9-17.9) displayed a JTC reasoning bias versus 19% of BPD (OR = 2.5, 95% CI: 0.8-7.8) and 9% of controls. JTC was not associated with level of psychotic symptoms or specifically delusionality across the different groups. Differences between FEP and controls were independent of sex, educational level, cannabis use and IQ. After one year, 47.8% of FEP with JTC at baseline again displayed JTC. CONCLUSIONS: JTC in part reflects trait vulnerability to develop disorders with expression of psychotic symptoms.
