[The Barratt Impulsiveness Scale-Brief-8 in an Incarcerated Sample: Suicide Risk, Impulsivity and Mindfulness].

INTRODUCTION: Suicide attempts and their consequences have been the leading causes of death among prisoners. Meta-analyses suggest that the main risk factors are current suicidal ideation, the presence of a mental disorder, high perceived stress levels, previous suicidal attempts or self-harm, and institutional and criminogenic variables. Empirical evidence is consistent with the integrated motivational-volitional model of suicidality, which also emphasizes the role of impulsivity in suicidal behaviour. The main objectives of our research are: (a) factor analysis of the Barratt Impulsiveness Scale-Brief-8 (BIS-R-8); (b) examination of the mental health status of prisoners, and the suicidal risk factors in our sample; (c) modeling the effect of mindfulness skills on the main risk factors. METHODS: In our cross-sectional survey, we matched a sample of inmates to a convenience sample according to gender and age (N=378). Based on our hypotheses, we examined the factor structure and reliability of the BIS-R-8. An independent sample t-test was used for comparison, and a two-step linear regression and mediation modeling were used to examine the risk of suicide. RESULTS: Based on factor analysis, the BIS-R-8 can be used as a unidimensional scale. A two-factor structure with cognitive and behavioral impulsivity subscales has also been confirmed. However, the internal and external reliability of the one-factor structure proved to be better. Depression, hopelessness, perceived stress and impulsivity turned out to be of higher level in the prisoner sample; lower levels of coping skills, self-esteem, mindfulness skills and well-being were also confirmed. Depression and perceived stress level seems to be the main modifiable risk factors for suicidal thoughts in the total and prisoner's sample. Previous suicide attempts and non-suicidal self-harm are the main unmodifiable risk factors of suicidal thoughts. Low level of mindfulness skills directly and indirectly via perceived stress explains 50% of the heterogeneity in depression. DISCUSSION: In correctional institutions BIS-8-R can be a suitable screening tool for measuring impulsivity as a suicide risk factor. Mindfulness-based interventions seem promising for improving the mental health status of prisoners and reducing the risk of suicide.

[Borderline personality disorder and non-suicidal self-injury: the role of mindfulness training in risk reduction].

INTRODUCTION: Due to patients diagnosed with borderline personality disorder (BPD) can engage risky behaviors, it is necessary to develop evidence based interventions in healthcare that can help to reduce the most pressing problems. BPD-specific cognitive therapy-based mindfulness training (MBCT) can be a solution to this challange. LITERATURE REVIEW: Non-suicidal self-injury (NSSI) is a significant predictor of subsequent suicide attempts and occurs in 80% of BPD patients. It is related to impulse- and emotion-dysregulation (cognitive-emotional model), as well as the deficit of mindfulness skills, which are also key difficulties in BPD (emotional cascade model, mindfulness deficit theory). The cognitive-emotional reactivity model of NSSI based on the reactivity model in recurrent depression, the four-function model and theories above. The model differs situational, cognitive, emotional, physiological, and behavioral factors that can trigger or maintain NSSI, and it also helps to determine intervention points. STUDY PROTOCOL: Our hypothesis is that the 8-week MBCT training is more effective in developing mindfulness skills, emotion- and impulse control, and in reducing self-harm also than waiting list or supportive therapy. Participants are BPD patients with NSSI, in a quasi-experimental repeated measure design, planned sample size is N=60 per group. Before the training there is a two-stage interview procedure, patients fill out a questionnaire survey and they have to sign a suicide prevention contract. The planned waiting time between the first interview and the start of the training is 8-12 weeks. The group sessions are based on the MBCT training protocol designed to reduce the risk of suicide, supplemented with BPD-specific elements (specific psychoeducation, loving-kindness meditation). DISCUSSION: Based on the effectiveness of small-sample research, our aim is to test the effectiveness of MBCT training among BPD patients based on the above protocol.
