ABSTRACT

Background: Intrusive memories form a core symptom of Posttraumatic Stress Disorder (PTSD). Based on concepts of visuospatial interference and memory-updating accounts, technological innovations aim to attenuate such intrusions using visuospatial interventions.Objective: This study aims to test the effect of a visuospatial Tetris-based intervention versus a verbal condition (Wiki) and a never-targeted control (no intervention) on intrusion frequency.Method: A randomized crossover trial was conducted including N = 38 PTSD patients who had at least 3 distinct intrusive memories of trauma. After both 2 weeks (intervention 1) and 4 weeks (intervention 2), one of the three memories was randomly selected and either the visuospatial intervention (memory reminder of a traumatic memory + Tetris) or verbal condition (reading a Wikipedia article + answering questions) was performed on their first memory in randomized order. In the week 4 session, the patient conducted the other intervention condition on their second memory (crossover). The third memory was never targeted (no intervention). Daily occurrence of intrusions over 8 weeks was collected using a diary and analysed using mixed Poisson regression models.Results: Overall, there was no significant reduction in intrusion frequency from either intervention compared to each other, and to no intervention control (relative risk Tetris/Wiki: 0.947; p = .31; relative risk no intervention/Tetris: 1.060; p = .15; relative risk no intervention/Wiki: 1.004; p = .92).Conclusions: There was no effect of either intervention on intrusions when administered in a crossover design where participants received both interventions. Design shortcomings and consequences for future studies are discussed.


Visuospatial interventions, including the computer game Tetris, have been studied as a potential means to decrease intrusive memories, a core feature of Posttraumatic Stress Disorder.In this study, two interventions are tested in a crossover design with patients with intrusive memories after traumatic experiences.There was no effect of either the visuospatial intervention or the verbal condition in this design.

ABSTRACT

INTRODUCTION: Adults presenting to the ambulance service for diagnosed epilepsy are often transported to emergency departments (EDs) despite no clinical need. An alternative care pathway (CP) could allow paramedics to divert them from ED and instigate ambulatory care improvements. To identify the most promising CP configuration for subsequent testing, the COLLABORATE project surveyed people with epilepsy and family/friends who had recently used the English ambulance service to elicit preferences for 288 CP configurations for different seizures. This allowed CPs to be ranked according to alignment with service users' preferences. However, as well as being acceptable to users, a CP must be feasible. We thus engaged with paramedics, epilepsy specialists and commissioners to identify the optimal configuration. METHODS: Three Knowledge Exchange workshops completed. Participants considered COLLABORATE's evidence on service users' preferences for the different configurations. Nominal group techniques elicited views on the feasibility of users' preferences according to APEASE criteria. Workshop groups specified the configuration/s considered optimum. Qualitative data was analysed thematically. Utility to users of the specified CP configurations estimated using the COLLABORATE preference survey data. RESULTS: Twenty-seven participants found service users' preferences broadly feasible and outlined delivery recommendations. They identified enough commonality in preferences for different seizures to propose a single CP. Its configuration comprised: 1) patients staying where they were; 2) paramedics having access to medical records; 3) care episodes lasting <6 h; 4) paramedics receiving specialist advice on the day; 5) patient's GP being notified; and 6) a follow-up appointment being arranged with an epilepsy specialist. Preference data indicated higher utility for this configuration compared to current care. DISCUSSION: Stakeholders are of the view that the CP configuration favoured by service users could be NHS feasible. It should be developed and evaluated.

ABSTRACT

OBJECTIVES: Non-suicidal self-injury (NSSI) is theorized to be reinforced by its emotional consequences. Mental images of NSSI are commonly reported as occurring prior to NSSI. Based on the known functional properties of anticipatory mental imagery as an emotional and motivational amplifier, this study investigated whether NSSI mental imagery constitutes a proximal and dynamic mechanism underpinning NSSI risk. METHOD: An intensive ecological momentary assessment (EMA) study was conducted to track the occurrence and characteristics of NSSI mental imagery alongside NSSI urge and behavior in naturalistic settings. A sample of N = 43 individuals aged 17 to 24 with a history of repetitive NSSI completed EMA surveys seven times a day for 14 days. RESULTS: Mental preoccupation in the form of NSSI mental imagery-based flash-forwards to the actions, bodily sensations, and emotional benefits of NSSI was found to occur when NSSI urge was high but not when urge was low. Critically, objective cross-panel analyses showed that higher frequencies of NSSI imagery occurrence predicted greater future NSSI urge and increased likelihood of acting on urge, over and above current urge. CONCLUSIONS: Mental imagery of NSSI is not simply an epiphenomenal by-product of NSSI urge and may constitute a dynamic and proximal novel intervention target.

ABSTRACT

INTRODUCTION: To identify service users' preferences for an alternative care pathway for adults with epilepsy presenting to the ambulance service. METHODS: Extensive formative work (qualitative, survey and knowledge exchange) informed the design of a stated preference discrete choice experiment (DCE). This hypothetical survey was hosted online and consisted of 12 binary choices of alternative care pathways described in terms of: the paramedic's access to medical records/ 'care plan', what happens next (described in terms of conveyance), time, availability of epilepsy specialists today, general practitioner (GP) notification and future contact with epilepsy specialists. DCE scenarios were described as: (i) typical seizure at home. (ii) typical seizure in public, (iii) atypical seizure. Respondents were recruited by a regional English ambulance service and by national public adverts. Participants were randomised to complete 2 of the 3 DCEs. RESULTS: People with epilepsy (PWE; n = 427) and friends/family (n = 167) who completed the survey were representative of the target population. PWE preferred paramedics to have access to medical records, non-conveyance, to avoid lengthy episodes of care, availability of epilepsy specialists today, GP notification, and contact with epilepsy specialists within 2-3 weeks. Significant others (close family members or friends) preferred PWE experiencing an atypical seizure to be conveyed to an Urgent Treatment Centre and preferred shorter times. Optimal configuration of services from service users' perspective far out ranked current practice (rank 230/288 possible configurations). DISCUSSION: Preferences differ to current practice but have minimal variation by seizure type or stakeholder. Further work on feasibility of these pathways in England, and potentially beyond, is required.

ABSTRACT

ABSTRACTBackground: Many healthcare workers (HCWs) endured psychologically traumatic events at work during the coronavirus disease 2019 (COVID-19) pandemic. For some, these events are re-experienced as unwanted, recurrent, and distressing intrusive memories. Simple psychological support measures are needed to reduce such symptoms of post-traumatic stress in this population. A novel intervention to target intrusive memories, called an imagery-competing task intervention (ICTI), has been developed from the laboratory. The intervention includes a brief memory reminder cue, then a visuospatial task (Tetris® gameplay using mental rotation instructions for approximately 20 min) thought to interfere with the traumatic memory image and reduce its intrusiveness. The intervention has been adapted and evaluated in a randomized controlled trial (RCT) with Swedish HCWs (ClinicalTrials.gov identifier: NCT04460014).Objective: We aimed to explore how HCWs who worked during the COVID-19 pandemic experienced the use of a brief intervention to reduce their intrusive memories of work-related trauma.Method: Interpretative phenomenological analysis was used for in-depth understanding of the lived experiences of HCWs who used the intervention. Seven participants from the RCT were interviewed by an independent researcher without prior knowledge of the intervention. Interviews were conducted via telephone and transcribed verbatim.Results: Four general themes were generated: 'Triggers and troublesome images', 'Five Ws regarding support - what, when, why, by/with who, for whom', 'Receiving it, believing it, and doing it' and 'The intervention - a different kind of help'; the last two included two subthemes each. The results reflect participants' similarities and differences in their lived experiences of intrusive memories, support measures, and intervention impressions and effects.Conclusion: HCWs' experiences of the novel ICTI reflect a promising appraisal of the intervention as a potential help measure for reducing intrusive memories after trauma, and gives us a detailed understanding of HCWs' needs, with suggestions for its adaption for future implementation.Trial registration: ClinicalTrials.gov identifier: NCT04460014.


Many healthcare workers experience images or 'flashbacks' of traumatic experiences from their work during the COVID-19 pandemic.To ensure that individual needs are met, there is a need to tailor and refine current psychological support measures and their use for healthcare workers.The imagery-competing task intervention was perceived as acceptable, indicating its potential utility as a help measure to reduce intrusive memories after trauma.

ABSTRACT

BACKGROUND: Many intensive care unit (ICU) staff experience intrusive memories following work-related traumatic events, which can lead to long-term mental health outcomes and impact work functioning. There is a need for interventions that target intrusive memories in this population; however, factors such as mental health stigma and difficulty in fitting interventions into busy schedules can pose barriers. The Brief Gameplay Intervention For National Health Service Intensive Care Unit Staff Affected By COVID-19 Trauma (GAINS) study tested a brief, digital imagery-competing task intervention (including computer gameplay) with the aim of reducing the recurrence of intrusive memories, which holds promise for overcoming some of these barriers. OBJECTIVE: This substudy aims to explore barriers and facilitators to the uptake and practical use of the intervention by ICU staff, along with its acceptability, and iteratively explore the impact of intervention optimizations to further refine the intervention. METHODS: The GAINS study is a randomized controlled trial comparing access to a brief digital imagery-competing task intervention for 4 weeks with usual care followed by delayed access to the intervention. The participants were ICU staff who worked during the COVID-19 pandemic and experienced intrusive memories. All participants were sent a questionnaire at 4 weeks to gather data about intervention acceptability. Nested within the randomized controlled trial, a subset of 16 participants was interviewed, and data were analyzed using thematic analysis drawing from a framework approach. RESULTS: Both quantitative and qualitative data indicated high acceptability of the intervention. Intervention use data show that, on average, staff were able to target approximately 73% (3.64/4.88) of their intrusive memories and engaged with the Tetris component for the full 20 minutes per session. Overall, on the acceptability questionnaire, staff found the intervention easy to use, helpful, and highly acceptable. The interviews generated four themes: approach to the intervention, positives of the intervention, negatives of the intervention, and improvements and optimizations. Findings highlighted barriers that ICU staff experienced: stigma, feeling weak for seeking help, not wanting colleagues to know they were struggling, and skepticism. However, they provided suggestions on how barriers could be overcome and discussed the advantages of the intervention when compared with other treatments. Although participants described many positive aspects of the intervention, such as being easy to use, enjoyable, and leading to a reduction in the frequency or intensity of intrusive memories, they also raised practical issues for implementation. CONCLUSIONS: The intervention has the potential to overcome stigma and reduce the frequency of intrusive memories after traumatic events among ICU staff. Further refinement is needed to improve the adoption and reach of this intervention. A limitation is that we could not interview the National Health Service staff who were unable or unwilling to take part in the trial.

ABSTRACT

BACKGROUND: The purpose of this 6-month intervention pilot feasibility randomised trial was to test sending brief messages using mobile phones to promote self-management through taking medication as prescribed to people with type 2 diabetes. This was to inform the design and conduct of a future large-scale United Kingdom-based clinical trial and establish the feasibility of recruitment, the technology used, follow-up, and data collection. METHODS: A multicentre individually randomised, controlled parallel group trial in primary care, recruiting adults (≥ 35 years) with type 2 diabetes in England. Consenting participants were randomly allocated to receive short message system text messages up to four times a week, or usual care, for a period of 6 months; messages contained behavioural change techniques targeting medication use. The primary outcome was the rate of recruitment to randomisation of participants to the trial with a planned rate of 22 participants randomised per month. The study also aimed to establish the feasibility of follow-up at 6 months, with an aim of retaining more than 80% of participants. Data, including patient-reported measures, were collected at baseline and the end of the 6-month follow-up period, and a notes review was completed at 24 months. RESULTS: The trial took place between 26 November 2018 and 30 September 2019. In total 209 participants were randomly allocated to intervention (n = 103) or usual care (n = 106). The maximum rate of monthly recruitment to the trial was 60-80 participants per month. In total, 12,734 messages were sent to participants. Of these messages, 47 were identified as having failed to be sent by the service provider. Participants sent 2,864 messages to the automated messaging system. Baseline data from medical records were available for > 90% of participants with the exception of cholesterol (78.9%). At 6 months, a further HbA1c measurement was reported for 67% of participants. In total medical record data were available at 6 months for 207 (99.0%) of participants and completed self-report data were available for 177 (84.7%) of participants. CONCLUSION: The feasibility of a large-scale randomised evaluation of brief message intervention for people with type 2 diabetes appears to be high using this efficient design. Failure rate of sending messages is low, rapid recruitment was achieved among people with type 2 diabetes, clinical data is available on participants from routine medical records and self-report of economic measures was acceptable. TRIAL REGISTRATION: ISCTRN ISRCTN13404264. Registered on 10 October 2018.

ABSTRACT

BACKGROUND: Discharges against medical advice (DAMA) increase the risk of death. METHODS: We retrieved DAMA from five hospitals within a large health system and reviewed 10% of DAMA from the academic site between 2016 and 2021. RESULTS: DAMA increased at the onset of the pandemic. Patients who discharged AMA multiple times accounted for a third of all DAMA. Detailed review was completed for 278 patients who discharged AMA from the academic site. In this sample, women comprised 52% of those who discharged AMA multiple times. Relative to the proportion of all discharges from the academic site during the study period, Black patients were overrepresented among DAMA (21% vs. 34%, p < .05). Patients with multiple AMA discharges were younger, more likely to be unmarried, or have substance use disorders (SUD) than those who discharged AMA once. The most common reason for requesting premature discharge noted in n = 77, 28% of instances was related to patient obligations outside the hospital. Hospital policies and procedures contributed in n = 29, 10% of instances. Reasons for requesting premature discharge and documentation of key safety processes were similar by gender and race however the sample may be underpowered to detect differences. Capacity was evaluated in 109 (39%). Among those who consumed alcohol (n = 81 (29%)) or had SUDs (n = 112 (40%)), information on the amount or timing of last use was missing in n = 39 (48%) and n = 74 (66%), respectively. Critical tools to manage illness were provided in 45 (16%) of DAMA reviewed. CONCLUSIONS: Drivers of AMA discharge may differ by AMA discharge frequency. Recognition of the common reasons for requesting premature discharge may help destigmatize AMA discharges and also identifies early assessments by social work colleagues as an important prevention strategy. Opportunities also exist in anticipating and preventing withdrawal symptoms and in revising hospital practices that contribute to DAMA.

ABSTRACT

PURPOSE: The rising number of apps requires careful consideration in how these apps are being selected for students with extensive support needs in school-based settings. Current practices suggest that educational apps are being purchased without utilizing an evaluation tool to determine the quality or effectiveness of the apps. A systematic literature review was conducted to identify educational app evaluation tools for students with extensive support needs. MATERIALS AND METHODS: A three-phase search process (electronic database search, journal hand-search, and ancestral search) was conducted using 14 keywords to maximize the number of articles. A two-step coding procedure was conducted to ensure articles met the four inclusion criteria. A 15 criteria checklist was used to evaluate the methodological rigor of accepted articles. RESULTS: Findings focused on the type of app evaluation tools and their specific evaluation dimensions. A total of 107 articles were identified with 13 articles meeting the inclusion criteria. Stage 1 evaluated the methodological rigor of the app evaluation tools (M = 6.15, range 0.5 - 14). Stage 2 categorized the articles based on the type of evaluation tools (rubric = 5, rating scale = 6, checklist = 2). Stage 3 identified five evaluation dimensions (background, design features, usability, individualization, and overall impression). CONCLUSIONS: There is a lack of empirically tested evaluation tools for communication and educational apps, making it difficult to recommend a valid app evaluation tool. Thus, barriers are likely to persist in the effective identification of apps for students with extensive support needs.


There is a need for validated and reliable app evaluation tools as an essential mean to ensure there is a closer match between the student's needs and the app's features.Practitioners should carefully consider the evaluation approach as a holistic process that uses a valid and reliable tool, and that includes five evaluation dimensions.

ABSTRACT

Preventive evidence-based interventions for childbirth-related posttraumatic stress disorder (CB-PTSD) are lacking. Yet, 18.5% of women develop CB-PTSD symptoms following an unplanned caesarean section (UCS). This two-arm, multicentre, double-blind superiority trial tested the efficacy of an early single-session intervention including a visuospatial task on the prevention of maternal CB-PTSD symptoms. The intervention was delivered by trained maternity clinicians. Shortly after UCS, women were included if they gave birth to a live baby, provided consent, and perceived their childbirth as traumatic. Participants were randomly assigned to the intervention or attention-placebo group (allocation ratio 1:1). Assessments were done at birth, six weeks, and six months postpartum. Group differences in maternal CB-PTSD symptoms at six weeks (primary outcomes) and six months postpartum (secondary outcomes) were assessed with the self-report PTSD Checklist for DSM-5 (PCL-5) and by blinded research assessors with the Clinician-administered PTSD scale for DSM-5 (CAPS-5). Analysis was by intention-to-treat. The trial was prospectively registered (ClinicalTrials.gov, NCT03576586). Of the 2068 women assessed for eligibility, 166 were eligible and 146 were randomly assigned to the intervention (n = 74) or attention-placebo control group (n = 72). For the PCL-5, at six weeks, a marginally significant intervention effect was found on the total PCL-5 PTSD symptom count (ß = -0.43, S.E. = 0.23, z = -1.88, p < 0.06), and on the intrusions (ß = -0.73, S.E. = 0.38, z = -1.94, p < 0.0525) and arousal (ß = -0.55, S.E. = 0.29, z = -1.92, p < 0.0552) clusters. At six months, a significant intervention effect on the total PCL-5 PTSD symptom count (ß = -0.65, S.E. = 0.32, z = -2.04, p = 0.041, 95%CI[-1.27, -0.03]), on alterations in cognition and mood (ß = -0.85, S.E. = 0.27, z = -3.15, p = 0.0016) and arousal (ß = -0.56, S.E. = 0.26, z = -2.19, p < 0.0289, 95%CI[-1.07, -0.06]) clusters appeared. No group differences on the CAPS-5 emerged. Results provide evidence that this brief, single-session intervention carried out by trained clinicians can prevent the development of CB-PTSD symptoms up to six months postpartum.

ABSTRACT

Exposure to aversive footage online can affect our well-being, but to what extent does reading others' appraisals of this content modulate our affective responses? In a pre-registered online study (N = 170), we used a digital trauma film paradigm as an analogue for the naturalistic exposure to aversive visual content online. We investigated whether online social reappraisal about the film influenced acute affective responses and subsequent intrusive memories. First, we examined whether the digital trauma film paradigm induced similar affective responses as in-lab experiments (within-subjects; change in negative mood and intrusive memories of the film during seven days). Participants reported a negative mood change and experienced intrusive memories of the film, extending findings from in-lab experiments. Next, we tested a social reappraisal manipulation that provides written comments from (fictitious) previous participants (between-subjects; reading positive, negative, or no comments) modulated participants' affective responses. As predicted, relative to controls and negative comments, reading positive comments decreased negative mood. However, reading negative comments did not increase negative mood. Contrary to predictions, the social reappraisal manipulation did not modulate the number of intrusive memories. Findings suggest the benefit of positive social reappraisal for mitigating negative mood, but not intrusive memories following aversive film content online.

ABSTRACT

Intrusive memories (IMs) after traumatic events can be distressing and disrupt mental health and functioning. We evaluated the impact of a brief remotely-delivered digital imagery-competing task intervention on the number of IMs for intensive care unit (ICU) staff who faced repeated trauma exposure during the COVID-19 pandemic using a two-arm, parallel-group, single-blind randomised controlled trial, with the comparator arm receiving delayed access to active treatment (crossover). Eligible participants worked clinically in a UK NHS ICU during the pandemic and had at least 3 IMs of work-related traumatic events in the week before recruitment. Participants were randomly assigned (1:1) to immediate (weeks 1-4) or delayed (weeks 5-8) intervention access. Sequential Bayesian analyses to optimise the intervention and increase trial efficiency are reported elsewhere [1]. The primary endpoint for the pre-specified frequentist analysis of the final study population compared the number of IMs experienced in week 4 between the immediate and delayed access arms. Secondary outcomes included clinical symptoms, work functioning and wellbeing. Safety was assessed throughout the trial by scheduled questions and free report. All analyses were undertaken on an intention-to-treat basis (86 randomised participants). There were significantly fewer intrusive memories during week 4 in the immediate (median = 1, IQR = 0-3, n = 43), compared to the comparator delayed arm (median = 10, IQR = 6-17, n = 43), IRR 0.31, 95% CI: 0.20-0.48, p < 0.001. After crossover, the delayed arm also showed a significant reduction in IMs at week 8 compared to week 4. There were convergent findings for symptoms of PTSD, insomnia and anxiety, work engagement and burnout, general functioning and quality of life. The intervention was found safe and acceptable to participants. All adverse events were unrelated to the study. Our study provides the first evidence of a benefit on reducing IMs, improving other clinical symptoms, work functioning and wellbeing, as well as safety of a brief remotely-delivered digital imagery-competing task intervention. An efficacy trial with an active control and longer follow-up is warranted. The trial is registered at ClinicalTrials.gov (NCT04992390).

ABSTRACT

Distressing intrusive memories of a traumatic event are one of the hallmark symptoms of posttraumatic stress disorder. Thus, it is crucial to identify early interventions that prevent the occurrence of intrusive memories. Both, sleep and sleep deprivation have been discussed as such interventions, yet previous studies yielded contradicting effects. Our systematic review aims at evaluating existing evidence by means of traditional and individual participant data (IPD) meta-analyses to overcome power issues of sleep research. Until May 16th, 2022, six databases were searched for experimental analog studies examining the effect of post-trauma sleep versus wakefulness on intrusive memories. Nine studies were included in our traditional meta-analysis (8 in the IPD meta-analysis). Our analysis provided evidence for a small effect favoring sleep over wakefulness, log-ROM = 0.25, p < .001, suggesting that sleep is associated with a lower number of intrusions but unrelated to the occurrence of any versus no intrusions. We found no evidence for an effect of sleep on intrusion distress. Heterogeneity was low and certainty of evidence for our primary analysis was moderate. Our findings suggest that post-trauma sleep has the potential to be protective by reducing intrusion frequency. More research is needed to determine the impact following real-world trauma and the potential clinical significance.

ABSTRACT

Cognitive theories of post-traumatic stress disorder (PTSD) feature appraisal of trauma as a critical factor in the development and maintenance of the disorder. Here we explored appraisals of social trauma (severe rejection or humiliation). Participants were outpatients with social anxiety disorder (SAD) and clinically significant PTSD symptoms (PTSS) after social trauma (n = 15); two clinical control groups of either SAD (n = 32) or obsessive-compulsive disorder (OCD; n = 13); and a control group with no diagnoses (n = 38). Measures included a clinical interview to assess social trauma and related open-ended appraisals and the Posttraumatic Cognitions Inventory (PTCI). Raters blind to group assignment performed content analyses of appraisals. Results showed that the PTSS group scored significantly higher than either clinical group on the PTCI SELF subscale. Only the SELF subscale predicted a diagnosis of both PTSS and SAD. All but one PTSS participant reported primarily negative beliefs about their social trauma, and the most common categories were flawed self and others are critical or cruel. Post-traumatic appraisals implicated in the course of PTSD are significant in how individuals respond to social trauma, with negative self-cognitions linked to both PTSS and SAD.

ABSTRACT

Introduction: Suicidal intrusions are uncontrollable, intrusive mental images (e. g., visualizing a future suicidal act). They may also be called suicidal "flash-forwards." Despite the importance of integrating the assessment of suicidal intrusions into a clinical routine assessment, quick self-report screening instruments are lacking. This study describes the development of a new instrument-Suicidal Intrusions Attributes Scale (SINAS)-to assess the severity and characteristics of suicidal intrusions and examines its psychometric properties. Method: The sample included currently suicidal outpatients with elevated levels of depression recruited across mental health institutions in the Netherlands (N = 168). Instruments administered were 10-item SINAS, the Suicidal Ideation Attributes Scale (SIDAS), the Prospective Imagery Task (PIT), four-item Suicidal Cognitions Interview (SCI), and the Beck Depression Inventory (BDI-II). Results: An exploratory factor analysis identified a one-factor structure. The resulting SINAS demonstrated good internal consistency (Cronbach's α = 0.91) and convergent validity, as expected. Discussion: Overall, this study demonstrated acceptable levels of reliability and validity of the measure in a depressed clinical population with suicidal ideation. The SINAS may be a useful screening tool for suicidal intrusions in both research and clinical settings.

ABSTRACT

BACKGROUND: Intrusive mental imagery is associated with anxiety and mood instability within bipolar disorder and therefore represents a novel treatment target. Imagery Based Emotion Regulation (IBER) is a brief structured psychological intervention developed to enable people to use the skills required to regulate the emotional impact of these images. METHODS: Participants aged 18 and over with a diagnosis of bipolar disorder and at least a mild level of anxiety were randomly assigned (1:1) to receive IBER plus treatment as usual (IBER + TAU) or treatment as usual alone (TAU). IBER was delivered in up to 12 sessions overs 16 weeks. Clinical and health economic data were collected at baseline, end of treatment and 16-weeks follow-up. Objectives were to inform the recruitment process, timeline and sample size estimate for a definitive trial and to refine trial procedures. We also explored the impact on participant outcomes of anxiety, depression, mania, and mood stability at 16-weeks and 32-weeks follow-up. RESULTS: Fifty-seven (28: IBER + TAU, 27: TAU) participants from two sites were randomised, with 50 being recruited within the first 12 months. Forty-seven (82%) participants provided outcome data at 16 and 32-weeks follow-up. Thirty-five participants engaged in daily mood monitoring at the 32-week follow-up stage. Retention in IBER treatment was high with 27 (96%) attending ≥ 7 sessions. No study participants experienced a serious adverse event. DISCUSSION: The feasibility criteria of recruitment, outcome completion, and intervention retention were broadly achieved, indicating that imagery-focused interventions for bipolar disorder are worthy of further investigation.

ABSTRACT

OBJECTIVES: To pilot an exploration of older adults' future preferences using discrete choice experiments to understand who should provide dental examinations and treatment, where these services should be provided, and participants' willingness to pay and willingness to travel. BACKGROUND: The proportion of older adults in the general population is increasing and is recognised as a pressing public health challenge. MATERIALS AND METHODS: Older people aged 65 years and over were recruited into this study from the UK, Switzerland and Greece. Drawing on earlier stakeholder engagement, a set of choice experiments are developed to explore the future preferences of older people for dental examinations and dental treatment, as they anticipated losing their independence. These were presented to the participants using a range of platforms, because of the COVID pandemic. Data were analysed in STATA using a random-effects logit model. RESULTS: Two hundred and forty-six participants (median age 70 years) completed the pilot study. There was a strong preference across all countries for a dentist to undertake a dental examination (Greece: ß = 0.944, Switzerland: ß = 0.260, UK ß = 0.791), rather than a medical doctor (Greece: ß = -0.556, Switzerland: ß = -0.4690, UK: ß = -0.468). Participants in Switzerland and the UK preferred these examinations to be undertaken in a dental practice (Switzerland: ß = 0.220, UK: ß = 0.580) while participants in Greece preferred the dental examination to be undertaken in their homes (ß = 1.172). Greek participants preferred dental treatment to be undertaken by a specialist (ß = 0.365) in their home (ß = 0.862), while participants from the UK and Switzerland preferred to avoid any dental treatment at home (Switzerland: ß = -0.387; UK: ß = -0.444). Willingness to pay analyses highlighted that participants in Switzerland and the UK were willing to pay more to ensure the continuity of future service provision at a family dental practice (Switzerland: ß = 0.454, UK: ß = 0.695). CONCLUSION: Discrete choice experiments are valuable for exploring older people's preferences for dental service provision in different countries. Future larger studies should be conducted to further explore the potential of this approach, given the pressing need to design services that are fit for purpose for older people. Continuity of dental service provision is considered as important by most older people, as they anticipate losing their dependence.

ABSTRACT

Traumatic events lead to distressing memories, but such memories are made all the worse when they intrude to mind unbidden and recurrently. Intrusive memories and flashbacks after trauma are prominent in several mental disorders, including post-traumatic stress disorder and can persist for years. Critically, the reduction of intrusive memories provides a treatment target. While cognitive and descriptive models for psychological trauma exist, these lack formal quantitative structure and robust empirical validation. Here, using techniques from stochastic process theory, we develop a mechanistically driven, quantitative framework to extend understanding of the temporal dynamic processes of trauma memory. Our approach is to develop a probabilistic description of memory mechanisms to link to the broader goals of trauma treatment. We show how the marginal gains of treatments for intrusive memories can be enhanced as key properties (intervention strength and reminder strength) of the intervention and memory consolidation (probability memories are labile) vary. Parametrizing the framework with empirical data highlights that while emerging interventions to reduce occurrence of intrusive memories can be effective, counterintuitively, weakening multiple reactivation cues may help reduce intrusive memories more than would stronger cues. More broadly, the approach provides a quantitative framework for associating neural mechanisms of memory with broader cognitive processes.
