Sleep recordings in individuals with borderline personality disorder before and after trauma therapy

Interventions to improve the sleep quality of adults with personality disorder: A systematic review

Poor quality sleep is common for people who have a diagnosis of personality disorder (PD). Core cognitive and behavioral features of PD may cause and perpetuate poor sleep, but to date, no review has collated the evidence on the efficacy of interventions to improve sleep quality for people with PD. Structured searches for interventional studies among adults with PD and reporting validated measures of sleep quality were conducted up to November 2022 in multiple databases. Single-case reports were excluded. Study quality was assessed with standardized risk of bias tools. Unreported data was sought systematically from authors. This review was pre-registered with an international prospective register of systematic reviews (PROSPERO) (CRD42021282105). Of the 3503 identified studies, nine met inclusion criteria, representing a range of psychological, pharmaceutical, and other interventions and outcome measures. Meta-analytic methods were not feasible because of the serious risk of bias in all studies, and results were therefore synthesized narratively. There is limited and low-quality evidence of the effects of a variety of interventions to improve the sleep quality of people living with PD. Further research might consider specifically including people diagnosed with PD in trials of sleep interventions and using sleep outcome measures in trials of established PD treatments.

Effects of sleep disturbance on trauma-focused psychotherapy outcomes in posttraumatic stress disorder: A systematic review

This study aimed to synthesize existing research on the effects of sleep disturbances on trauma-focused psychotherapy outcomes in adults with posttraumatic stress disorder (PTSD). A systematic review using PubMed, PsycINFO, Embase, Web of Science, and PTSDpubs was performed up to April 2021. Two independent reviewers screened articles for inclusion, performed data extraction, and assessed risk of bias and certainty of the evidence. Narrative synthesis was conducted based on the type of sleep disorder symptom assessed. Sixteen primary studies were included in this review, the majority of which had a high overall risk of bias. Results suggested that sleep disorder symptoms were associated with higher overall PTSD severity across treatment; however, they did not interfere with treatment effectiveness, with the exception of sleep-disordered breathing. Improvements in insomnia, sleep duration, and sleep quality during treatment were associated with greater treatment gains. Certainty of the evidence ranged from low to very low. These results suggest that it may not be necessary to address sleep disorder symptoms prior to initiating trauma-focused psychotherapy. Instead, concurrent treatment of sleep- and trauma-related symptoms may be most beneficial. Continued research is needed to clarify the mechanistic relationship between sleep and treatment outcomes and to guide clinical decision-making.

The effects of narrative exposure therapy on COVID-19 patients with post-traumatic stress symptoms: A randomized controlled trial

BACKGROUND

With the global attack of Coronavirus Disease 2019 (COVID-19), cases with Post-traumatic Stress Disorder (PTSD) have been increasing steadily, which seriously affects the quality of life of patients and as such, seeking effective treatments is an urgent matter. Narrative Exposure Therapy (NET) is a typical cognitive behavioral therapy targeting trauma-related psychological disorders and may be an effective intervention.

METHODS

A total of 111 COVID-19 patients near the discharge stage with positive screening results for posttraumatic stress symptoms (PTSS) were randomly assigned (1:1) to either the study group or the control group. The study group received NET and personalized psychological intervention, while the control group only received personalized psychological intervention. PTSS, depression, anxiety and sleep quality were measured pre- and post-intervention to evaluate the effect of NET. This trial was registered with the International Standard Randomized Clinical Trial Registry (No. ChiCTR2000039369).

RESULTS

NET participants showed a significantly greater PTSS reduction in comparison with the control group after the intervention. Improvement in sleep quality, anxiety and depression after the intervention were pronounced but not significantly different between the two treatment groups.

LIMITATIONS

The assessors weren't blinded for the convenience of measurement and protection of participants' psychological security.

CONCLUSIONS

NET likely had a positive impact on PTSS of COVID-19 patients. Clinical staff should consider applying NET to improve the psychological well-being of patients who have experienced an epidemic such as COVID-19.

Insomnia in Patients with Borderline Personality Disorder

OBJECTIVE

Both sleep disorders and BPD are prevalent in the population, and one is often a comorbidity of the other. This narrative review aims to assess contemporary literature and scientific databases to provide the current state of knowledge about sleep disorders in patients with borderline personality disorder (BPD) and clinical suggestions for managing sleep disorders in BPD patients and future research direction.

METHODS

Articles were acquired via PubMed and Web of Science, and papers published between January 1980 and October 2020 were extracted. Authors made a series of literature searches using the keywords: Sleep problems, Insomnia, Nightmares, Obstructive sleep apnea, Borderline personality disorder. The inclusion criteria were: published in peer-reviewed journals; studies in humans; or reviews on the related topic; English language. The exclusion criteria were: abstracts from conferences; commentaries; subjects younger than 18 years. After an inspection of the full texts, 42 papers from 101 were selected. Secondary documents from the reference lists of the primary designated papers were searched, assessed for suitability, and included. In total, 71 papers were included in the review process.

RESULTS

Sleep disturbance is common among patients with BPD. Nevertheless, the number of investigations is limited, and the prevalence differs between 5-45%. Studies assessing objective changes in sleep architecture in BPD show inconsistent results. Some of them identify REM sleep changes and a decrease in slow-wave sleep, while other studies found no objective sleep architecture changes. There is also a higher prevalence of nightmares in patients with BPD. Untreated insomnia can worsen BPD symptoms via interference with emotional regulation. BPD itself seems to influence the subjective quality of sleep significantly. Proper diagnosis and treatment of sleep disorders in patients with BPD could lead to better results in therapy. Psychotherapeutic approaches can improve both sleep disorders and BPD symptoms.

CONCLUSION

Recognising and managing sleep disorders in patients with BPD may help alleviate the disorder's symptoms. Treatment of people with BPD may be more effective if the treatment plan explicitly addresses sleep problems. Further research is needed to reach reliable conclusions.

Adolescent Sleep Disturbance, Emotion Regulation and Borderline Features in an Inpatient Setting

OBJECTIVE

The current study aimed to examine the relation between sleep disturbance, emotion dysregulation and borderline personality features in adolescent inpatients.

METHOD

N = 217 adolescents (67.1% female; ages 12-17) with the following racial/ethnic breakdown: 67.4% White, 3.7% Hispanic, 2.8% Asian, 1.8% African American, and 6.4% multiracial) completed self-report measures of sleep disturbance, emotion dysregulation and borderline personality symptoms at admission to, discharge from, and at 6-months-post discharge from an inpatient psychiatric hospital. Group comparison and path analyses were conducted to examine differences in sleep disturbance between those with and without borderline personality disorder and the mediating role of emotion dysregulation in the relation between sleep disturbance and borderline personality features.

RESULTS

Borderline personality features and emotion dysregulation were significantly related to indices of sleep disturbance. Path models revealed that some sleep disturbance indices at admission directly predicted levels of borderline features at discharge and at 6-months-post-discharge. However, none of the indirect pathways between sleep disturbance at admission, emotion dysregulation at discharge, and borderline features at discharge or 6-months post-discharge were significant.

CONCLUSIONS

Findings are consistent with prior literature which suggest that a unique relation exists between sleep disturbance and BPD, beyond comorbid depression symptoms. However, contrary to our hypotheses, the current study did not provide empirical support for the mediating role of emotion regulation in this relation. These findings have implications for existing personality disorder and sleep interventions and suggest further research into the mechanisms underlying the relation between sleep disturbance and borderline personality pathology is necessary.

Effects of Narrative Exposure Therapy on Posttraumatic Stress Disorder, Depression, and Insomnia in Traumatized North Korean Refugee Youth

Refugees affected by multiple traumatic stressors are at high risk for developing trauma-related mental disorders, including posttraumatic stress disorder (PTSD), depression, and insomnia, which is sometimes overlooked. The present study examined the effectiveness of narrative exposure therapy (NET) on trauma-related symptoms in a sample of North Korean refugee youth. We focused on sleep patterns in addition to changes in symptom severity for PTSD, depression, and internalizing and externalizing symptoms. North Korean refugee youth (N = 20) with PTSD were assigned to either an NET-based treatment group or a control group, which consisted of treatment as usual (TAU). There were clinically significant reductions in PTSD, depression, and internalizing and externalizing symptoms for the NET group, Hedges' g = 3.6, but not the TAU group. The change in diagnostic status for PTSD was more notable for participants in the NET group compared to the TAU group. Of note, NET also produced a significant improvement in insomnia symptoms and sleep quality, Hedges' g = 2.1. The substantial recovery regarding overall posttraumatic symptoms in the NET group was observed 2 weeks after the end of treatment and remained stable at 6-month follow-up. The results of the present study suggest that NET may be a treatment option for traumatized North Korean refugee youth and may also be effective for the treatment of sleep problems that arise from traumatic experiences.

The Contribution of Posttraumatic Stress Disorder and Depression to Insomnia in North Korean Refugee Youth

Refugees are exposed to multiple traumatic and stressful events and thereby are at higher risk for developing a variety of psychological sequelae including posttraumatic stress disorder (PTSD). However, the relation of PTSD to other mental health conditions has not been fully revealed in refugee populations. The present study investigated relationships among trauma exposure, PTSD, depression, and insomnia in North Korean refugee youth. Seventy-four refugee youth were assessed for exposure to traumatic events, PTSD, depression, and insomnia symptoms. The results showed high rates of multiple trauma exposures among the refugee youth and high incidences of co-occurring symptoms of PTSD and insomnia in those who have multiple trauma. Furthermore, the overall symptoms and four cluster symptoms of PTSD were strongly correlated with insomnia in addition to depression. In the path model to predict insomnia, PTSD affected insomnia only through depression, indicating that the greater the levels of PTSD suffered, the greater the likelihood for developing sleep problems via depression. The present study indicates how sleep problems relate to trauma-related symptoms, i.e., PTSD and depression in refugee populations, and highlights the need for further investigation of the specific relation between sleep problems and trauma-related symptoms for effective evaluation and intervention.
