The treatment of PTSD in refugees and asylum seekers using imagery rescripting within an NHS setting.

BACKGROUND: Refugees and asylum seekers present with high levels of post-traumatic stress disorder (PTSD), whilst little research has been conducted to assess the effectiveness or acceptability of psychological interventions for this group. Imagery rescripting is effective in reducing distressing intrusive memories within a range of conditions. The current study evaluates this approach for the treatment of PTSD in refugees and asylum seekers within a UK NHS service. AIMS: To evaluate the clinical outcomes of using imagery rescripting for the treatment of PTSD in UK-based refugees and asylum seekers. METHOD: Ten adult service-users from an NHS specialist service with a primary diagnosis of PTSD were recruited as part of routine service delivery. A multiple baseline design was used with participants randomly allocated to a baseline varying from 5 to 9 weeks. A baseline wait-period was followed by up to five sessions of psychoeducation and treatment preparation, in turn followed by up to 10 sessions of imagery rescripting. The Post-traumatic Symptom Scale (PSS) and Physical Health Questionnaire-9 (PHQ-9) were collected every week during baseline, at end of treatment and weekly for 5 weeks after treatment, and again at 12-week follow-up. Data were analysed with mixed regression. RESULTS: Results indicate a significant improvement both in PTSD symptoms and mood, and that this was attributable to the imagery rescripting phase of the intervention, and not the passage of time or non-specific therapy factors. CONCLUSIONS: Evidence indicates imagery rescripting to be a safe and effective treatment choice for PTSD in refugees and asylum seekers.

Melatonin Supplementation in Undetermined Pediatric Deaths.

Since 2015, the North Carolina Office of the Chief Medical Examiner has investigated seven deaths of infants and toddlers, aged 2 months to 3 years, with exogenous melatonin detected upon toxicological analysis. Melatonin concentrations ranged from 3 to 1,400 ng/mL in postmortem whole blood. While the cause and the manner of all seven deaths were classified as undetermined, the analytical findings are noteworthy. Melatonin is generally considered a safe, natural product appearing in many over-the-counter supplements geared toward young children to facilitate calmness and improve sleep. Melatonin is a neurohormone, which regulates not only circadian rhythms and natural sleep but also other physiological functions. Endogenous melatonin production, derived from essential amino acid metabolism, does not begin until pineal gland maturation at ∼3 months of age with concentrations in plasma peaking during periods of darkness at ∼0.2 ng/mL. Administering commercially available melatonin supplements to infants results in levels substantially greater than endogenous sources, which should not be assumed to be safe just because of their endogenous nature. The finding of exogenous concentrations in some postmortem pediatric cases warrants attention. Several topics of interest surrounding these postmortem melatonin findings will be considered, such as minimal regulatory control over commercial products as well as the potential impact on hazardous sleeping conditions. This manuscript will outline the physiological effects of melatonin and detail the case studies from the North Carolina medical examiner system. Forensic toxicology laboratories should consider including melatonin at exogenous concentrations in their testing schemes for appropriate postmortem infant and toddler cases.

Targeting intrusive imagery using a competing task technique: a case study.

BACKGROUND: Even in cases with complexity, simple techniques can be useful to target a specific symptom. Intrusive mental images are highly disruptive, drive emotion, and contribute to maintaining psychopathology. Cognitive science suggests that we might target intrusive images using competing tasks. AIMS: We describe an imagery competing task technique within cognitive behavioural therapy (CBT) with a patient with bipolar disorder and post-traumatic stress disorder (PTSD) symptoms. The intervention - including Tetris computer game-play - was used (1) to target a specific image within one therapy session, and (2) to manage multiple images in daily life. METHOD: A single case (AB) design was used. (1) To target a specific image, the patient brought the image to mind and, after mental rotation instructions and game-play practice, played Tetris for 10 minutes. Outcomes, pre- and post-technique, were: vividness/distress ratings when the image was brought to mind; reported intrusion frequency over a week. (2) To manage multiple images, the patient used the intervention after an intrusive image occurred. Outcomes were weekly measures of: (a) imagery characteristics; (b) symptoms of PTSD, anxiety, depression and mania. RESULTS: (1) For the target image, there were reductions in vividness (80% to 40%), distress (70% to 0%), and intrusion frequency (daily to twice/week). (2) For multiple images, there were reductions from baseline to follow-up in (a) imagery vividness (38%), realness (66%) and compellingness (23%), and (b) PTSD symptoms (Impact of Events Scale-Revised score 26.33 to 4.83). CONCLUSION: This low-intensity intervention aiming to directly target intrusive mental imagery may offer an additional, complementary tool in CBT.

Imagery-Focused Cognitive Therapy (ImCT) for Mood Instability and Anxiety in a Small Sample of Patients with Bipolar Disorder: a Pilot Clinical Audit.

BACKGROUND: Despite the global impact of bipolar disorder (BD), treatment success is limited. Challenges include syndromal and subsyndromal mood instability, comorbid anxiety, and uncertainty around mechanisms to target. The Oxford Mood Action Psychology Programme (OxMAPP) offered a novel approach within a cognitive behavioural framework, via mental imagery-focused cognitive therapy (ImCT). AIMS: This clinical audit evaluated referral rates, clinical outcomes and patient satisfaction with the OxMAPP service. METHOD: Eleven outpatients with BD received ImCT in addition to standard psychiatric care. Mood data were collected weekly from 6 months pre-treatment to 6 months post-treatment via routine mood monitoring. Anxiety was measured weekly from start of treatment until 1 month post-treatment. Patient feedback was provided via questionnaire. RESULTS: Referral and treatment uptake rates indicated acceptability to referrers and patients. From pre- to post-treatment, there was (i) a significant reduction in the duration of depressive episode relapses, and (ii) a non-significant trend towards a reduction in the number of episodes, with small to medium effect size. There was a large effect size for the reduction in weekly anxiety symptoms from assessment to 1 month follow-up. Patient feedback indicated high levels of satisfaction with ImCT, and underscored the importance of the mental imagery focus. CONCLUSIONS: This clinical audit provides preliminary evidence that ImCT can help improve depressive and anxiety symptoms in BD as part of integrated clinical care, with high patient satisfaction and acceptability. Formal assessment designs are needed to further test the feasibility and efficacy of the new ImCT treatment on anxiety and mood instability.

Intrusive images and "hotspots" of trauma memories in Posttraumatic Stress Disorder: an exploratory investigation of emotions and cognitive themes.

This study aimed to investigate the emotions and cognitions contained in "hotspots" of memory for trauma, as well as their associated images. Thirty-two participants at a specialist outpatient trauma clinic had experienced a range of traumatic events and met diagnostic criteria for Posttraumatic Stress Disorder (PTSD). Data were collected within an agreed protocol, involving reliving therapy. Patients described the different intrusive images of the trauma that they were re-experiencing. Their reports of cognitions and emotions during "hotspots" in their memory of the traumatic experience were recorded as part of reliving therapy. Hotspots refer to moments of peak emotional distress during the event. There was a high degree of match reported between intrusive images and hotspots. The cognitive and emotional contents of hotspots were qualitatively analysed into themes. The relative of frequency of these peritraumatic themes is presented. The exploratory findings are discussed with respect to our understanding and treatment of intrusive imagery in PTSD.
