ABSTRACT
OBJECTIVES: Recurrent strokes are associated with greater disability and mortality than first-time strokes. However, adherence to secondary stroke prevention medications has been reported to be suboptimal. We assessed medication adherence to antihypertensives, antiplatelets, and statins after acute ischemic stroke and identified factors associated with non-adherence behavior to each drug class. METHODS: This single center study is an extension of a larger prospective cohort study of ischemic stroke patients assessed at an outpatient post stroke clinic. Medication adherence behavior and medication knowledge was determined by direct questioning, and perceptions towards medications via the Beliefs about Medicines Questionnaire. Factors associated with non-adherence in each drug class were determined using logistic regression. RESULTS: Rates of adherence differed between antihypertensives (77.9%), antiplatelets (80.3%), and statins (64.7%) (p < 0.001) amongst the 193 patients surveyed. Non-adherence to antihypertensives was associated with living alone, taking < 5 medications, and stronger beliefs that medications are harmful. For antiplatelets, non-diabetic patients and patients with stronger beliefs that medications are harmful were more likely to be non-adherent. Patients non-adherent to statins were more likely to have a longer time since ischemic event and have a transient ischemic attack as the index event. CONCLUSIONS: Overall, medication adherence behavior to secondary stroke prevention medications was poor, with statins the least adhered to. Factors associated with non-adherence to each drug class could guide the development of tailored interventions to improve adherence to secondary stroke prevention medications.

AIMS: This study aimed to (i) evaluate the effectiveness of mindfulness-based interventions in improving self-efficacy, reducing stress and anxiety among peritoneal dialysis patients, and (ii) compare the most effective method of mindfulness based interventions. METHODS: This randomized three-arm controlled trial recruited first-time peritoneal dialysis patients from the peritoneal dialysis outpatient clinic in Singapore. Patients were randomly allocated to either video-assisted mindfulness training, therapist-assisted mindfulness training or treatment-as-usual. All groups received 4.5 days of structured peritoneal dialysis training at the peritoneal dialysis centre, while video-assisted mindfulness training and therapist-assisted mindfulness training groups were taught additional mindfulness-based techniques. The perceived stress scale, self-efficacy, and anxiety (State and Trait Anxiety Inventory) were measured at baseline, 4- and 12 weeks post-randomization, using reliable and valid instruments. RESULTS: Thirty-nine patients were recruited (13 in each group). All the therapies showed a significant time trend in anxiety. Only therapist- and video-assisted mindfulness training showed a significant trend in perceived stress scale scores but not treatment-as-usual. All Intervention X Time interactions were not significant. Patients in therapist- and video-assisted mindfulness training groups had reduced perceived stress scale scores compared to treatment-as-usual at week 12. CONCLUSION: This study demonstrated the potential of mindfulness-based interventions in reducing stress among first-time PD patients.

Mindfulness-based interventions are showing increasing promise as a treatment for psychological disorders, with improvements in cognition and emotion regulation after intervention. Understanding the changes in functional brain activity and neural plasticity that underlie these benefits from mindfulness interventions is thus of interest in current neuroimaging research. Previous studies have found functional brain changes during resting and task states to be associated with mindfulness both cross-sectionally and longitudinally, particularly in the executive control, default mode and salience networks. However, limited research has combined information from rest and task to study mindfulness-related functional changes in the brain, particularly in the context of intervention studies with active controls. Recent work has found that the reconfiguration efficiency of brain activity patterns between rest and task states is behaviorally relevant in healthy young adults. Thus, we applied this measure to investigate how mindfulness intervention changed functional reconfiguration between rest and a breath-counting task in elderly participants with self-reported sleep difficulties. Improving on previous longitudinal designs, we compared the intervention effects of a mindfulness-based therapy to an active control (sleep hygiene) intervention. We found that mindfulness intervention improved self-reported mindfulness measures and brain functional reconfiguration efficiency in the executive control, default mode and salience networks, though the brain and behavioral changes were not associated with each other. Our findings suggest that neuroplasticity may be induced through regular mindfulness practice, thus bringing the intrinsic functional configuration in participants' brains closer to a state required for mindful awareness.

OBJECTIVES: Current cognitive screening and diagnostic instruments rely on visually dependent tasks and are, therefore, not suitable to assess cognitive impairment (CI) in visually impaired older adults. We describe the content development of the VISually Independent test battery Of NeuroCOGnition (VISION-Cog)-a new diagnostic tool to evaluate CI in visually impaired older Singaporean adults. DESIGN: The content development phase consisted of two iterative stages: a neuropsychological consultation and literature review (stage 1) and an expert-panel discussion (stage 2). In stage 1, we investigated currently available neuropsychological test batteries for CI to inform constructions of our preliminary test battery. We then deliberated this battery during a consensus meeting using the Modified Nominal Group technique (stage 2) to decide, via agreement of five experts, the content of a pilot neuropsychological battery for the visually impaired. SETTING: Singapore Eye Research Institute. PARTICIPANTS: Stakeholders included researchers, psychologists, neurologists, neuro-ophthalmologists, geriatricians and psychiatrists. OUTCOME MEASURE: pilot VISION-Cog. RESULTS: The two-stage process resulted in a pilot VISION-Cog consisting of nine vision-independent neuropsychological tests, including the modified spatial memory test, list learning, list recall and list recognition, adapted token test, semantic fluency, modified spatial analysis, verbal subtests of the frontal battery assessment, digit symbol, digit span forwards, and digit span backwards. These tests encompassed five cognitive domains-memory and learning, language, executive function, complex attention, and perceptual-motor abilities. The expert panel suggested improvements to the clarity of test instructions and culturally relevant test content. These suggestions were incorporated and iteratively pilot-tested by the study team until no further issues emerged. CONCLUSIONS: We have developed a five-domain and nine-test VISION-Cog pilot instrument capable of replacing vision-dependent diagnostic batteries in aiding the clinician-based diagnosis of CI in visually impaired older adults. Subsequent phases will examine the VISION-Cog's feasibility, comprehensibility and acceptability; and evaluate its diagnostic performance.

OBJECTIVES: We pilot-tested the VISually Independent test battery Of NeuroCOGnition (VISION-Cog) to determine its feasibility, comprehensibility and acceptability in evaluating cognitive impairment (CI) in visually impaired older Asian adults. DESIGN: The VISION-Cog was iteratively fine-tuned through pilot studies and expert-panel discussion. In the first pilot study (Stage 1), we recruited 15 visually impaired and cognitively normal participants aged ≥60 years to examine the pilot VISION-Cog's feasibility (length of time to administer), comprehensibility (clarity of instructions) and acceptability (participant burden). We then presented the pilot results to the expert panel (Stage 2) who decided via agreement on a revised version of the VISION-Cog. Subsequently, we conducted a second pilot study (Stage 3) on another four participants to ascertain improvement in feasibility, comprehensibility and acceptability of the revised version. SETTING: Singapore Eye Research Institute. PARTICIPANTS: Nineteen Asian adults aged ≥60 years with visual impairment (defined as near visual acuity worse than N8) were recruited. OUTCOME MEASURE: Revised VISION-Cog. RESULT: The VISION-Cog was deemed feasible, taking approximately 60 min to complete on average. All participants agreed that the test instructions were clear, and the battery did not cause undue discomfort or frustration. The data collector rated all tests as very user-friendly (score of 5/5). Minor modifications to the pilot VISION-Cog were suggested by the panel to improve its safety, clarity of instructions and content validity, which were incorporated and iteratively tested in the second pilot study until no further issues emerged. CONCLUSIONS: Using an iterative mixed-methods process, we have developed a feasible, comprehensible and acceptable 5-domain and 9-item visually independent VISION-Cog test battery suitable to assist CI diagnosis in older adults with visual impairment. We will assess its diagnostic potential against clinician-based assessment of CI in subsequent phases.

BACKGROUND AND PURPOSE: Self-management programs enhance survival in stroke patients. However, they require patient-centered designs to be effective. The aim of this study was therefore to investigate the type of post-stroke self-management programs that appeal to stroke survivors, and to estimate their willingness to participate in such programs. METHODS: A Discrete Choice Experiment was administered to patients who had either a transient ischemic attack (TIA) or stroke within the past 3 years and were cognitively intact (i.e., stroke survivors). Stroke survivors were presented with eight choice tasks and asked to choose between 'No Program' and two hypothetical post-stroke management programs that varied by six attributes: Topics covered by the program; schedule of the program; frequency and duration of the sessions; number of participants; out-of-pocket registration fee for the whole program; and rewards for completing the program. RESULTS: The analysis involved 146 stroke survivors. Based on the mixed logit model, the predicted willingness to participate ranged from 53% to 76%. The most popular characteristics in a program were topics on health education and risk management, being scheduled during weekends as four sessions that are each 2 hours long and involve four participants, a registration fee of SGD50 (â¼USD36), and SGD500 (â¼USD359) reward for program completion. CONCLUSIONS: Interest in post-stroke self-management programs was high, with at least half of the sample showing interest in participating in these programs. Program features such as focusing on health education and risk management, charging a low registration fee, and offering incentives helped to increase the demand.

OBJECTIVE: Poor sleep is a modifiable risk factor for multiple disorders. Frontline treatments (e.g. cognitive-behavioral therapy for insomnia) have limitations, prompting a search for alternative approaches. Here, we compare manualized Mindfulness-Based Therapy for Insomnia (MBTI) with a Sleep Hygiene, Education, and Exercise Program (SHEEP) in improving subjective and objective sleep outcomes in older adults. METHODS: We conducted a single-site, parallel-arm trial, with blinded assessments collected at baseline, post-intervention and 6-months follow-up. We randomized 127 participants aged 50-80, with a Pittsburgh Sleep Quality Index (PSQI) score ⩾5, to either MBTI (n = 65) or SHEEP (n = 62), both 2 hr weekly group sessions lasting 8 weeks. Primary outcomes included PSQI and Insomnia Severity Index, and actigraphy- and polysomnography-measured sleep onset latency (SOL) and wake after sleep onset (WASO). RESULTS: Intention-to-treat analysis showed reductions in insomnia severity in both groups [MBTI: Cohen's effect size d = -1.27, 95% confidence interval (CI) -1.61 to -0.89; SHEEP: d = -0.69, 95% CI -0.96 to -0.43], with significantly greater improvement in MBTI. Sleep quality improved equivalently in both groups (MBTI: d = -1.19; SHEEP: d = -1.02). No significant interaction effects were observed in objective sleep measures. However, only MBTI had reduced WASOactigraphy (MBTI: d = -0.30; SHEEP: d = 0.02), SOLactigraphy (MBTI: d = -0.25; SHEEP: d = -0.09), and WASOPSG (MBTI: d = -0.26; SHEEP (d = -0.18). There was no change in SOLPSG. No participants withdrew because of adverse effects. CONCLUSIONS: MBTI is effective at improving subjective and objective sleep quality in older adults, and could be a valid alternative for persons who have failed or do not have access to standard frontline therapies.

Background: The Family Health Climate (FHC) is a family environment attribute postulated to influence the health behaviors of family members. It can be measured by domain scales for physical activity (FHC-PA) and nutrition (FHC-NU), which have been validated and used to identify health climate patterns in families in Western populations. To extend the use of the scales to Asian settings, this study aimed to adapt and validate the instruments for use in the multi-ethnic population of Singapore, accounting for language and cultural differences. Methods: In Part A (n = 40) to adapt the scales for the Singapore population, we performed cognitive interviews, face validity testing and pre-testing of the instruments (n = 40). Besides English, the scales were translated into Chinese and Malay. In Part B (n = 400), we performed exploratory and confirmatory factor analyses respectively on two random samples. We also tested for item discriminant validity, internal consistency reliability, construct validity, and measurement invariance. Results: The findings from the cognitive interviews in Part A led to scale adaptations to accommodate cultural and linguistic factors. In Part B, EFA on Sample I resulted in a three-factor model for the PA scale (accounting for 71.2% variance) and a four-factor model for the NU scale (accounting for 72.8% variance). CFA on Sample II indicated acceptable model fits: FHC-PA: χ2 = 192.29, df = 101, p < 0.001, χ2/df = 1.90; SRMR = 0.049; RMSEA = 0.067; CFI = 0.969; TLI = 0.963; FHC-NU: χ2 = 170.46, df = 98, p < 0.001, χ2/df = 1.74; SRMR = 0.036; RMSEA = 0.061; CFI = 0.967; TLI = 0.960. The scores of family members demonstrated significant agreement on the FHC-PA (Sg) [ICC(2, 2) = 0.77] and FHC-NU (Sg) [ICC(2, 2) = 0.75] scales. Findings suggest good evidence for item discriminant validity, internal consistency reliability, construct validity, and measurement invariance. Short versions of the scales were also developed. Conclusion: We adapted, translated and validated the scales for assessing the health climate of families in Singapore, including the development of short versions. The results showed good psychometric properties and the constructs had significant relationships with health behaviors and routines. Improving our understanding of family influences on individual health behavior will be important in developing multi-level strategies for health promotion and chronic disease prevention.

Older adults with poor sleep tend to show a discrepancy between objective and self-reported sleep parameters, which can trigger a vicious cycle that worsens their sleep complaints. Cognitive-behavioural therapy can reduce this discrepancy, but alternative behavioural therapies remain untested. The present exploratory study aimed to investigate the effects of mindfulness-based therapy for insomnia (MBTI) on reducing sleep discrepancies in comparison with a sleep hygiene, education, and exercise programme (SHEEP). Older adults were randomly allocated into the mindfulness-based therapy for insomnia group (n = 55) or the sleep hygiene, education, and exercise programme group (n = 58). Subjective and objective sleep parameters were measured using sleep diaries, polysomnography (PSG), and actigraphy. Sleep discrepancies were calculated using the Bland-Altman method for sleep onset latency (SOL) and wake after sleep onset (WASO). Additionally, correlations between the change in sleep discrepancies and the change in subjective sleep quality and trait mindfulness were measured within each group. Sleep onset latency discrepancy measured by polysomnography and actigraphy decreased significantly after the MBTI and SHEEP interventions. In contrast, there was no significant change in wake after sleep onset discrepancy in either group. The change in sleep onset latency discrepancy was correlated with the change in insomnia symptoms and objectively measured trait mindfulness. Mindfulness-based therapy for insomnia was effective in reducing sleep onset latency discrepancies and improving sleep perception in older adults with sleep disturbances, which in turn drove an improvement in sleep quality and insomnia symptoms. Increases in trait mindfulness may have been an important mechanism in improving sleep perception in the mindfulness-based therapy for insomnia group.

OBJECTIVES: We conducted a secondary analysis of the Mindfulness Sleep Therapy study, a randomized controlled trial testing Mindfulness-Based Therapy for Insomnia (MBTI) against a sleep hygiene education and exercise program (SHEEP). We investigated whether the interventions led to changes in sleep macroarchitecture (N2, N3 and REM), and microarchitecture (sleep fragmentation, slow wave activity, spectral band power) measured by ambulatory polysomnography (PSG). METHODS: 48 MBTI and 46 SHEEP participants provided usable PSG and subjective sleep quality data both pre- and post intervention. The interventions consisted of 8 weekly 2-hour group sessions, and daily practice. PSG data were staged according to the American Academy of Sleep Medicine criteria by 2 technicians blind to time point and condition. Repeated-measures ANOVA and permutation analysis were used to test for differences over time and between the interventions. RESULTS: Self-reported sleep quality improved in both study groups. We observed significant increases in N2 in MBTI but not SHEEP (p = .045), and significant increases in N3 in SHEEP but not MBTI (p = .012). No significant differences over time or between group were observed in N1, REM, or sleep fragmentation. Higher frequency non-REM EEG power decreased in SHEEP but not MBTI. Slow wave activity and slow wave activity dissipation did not differ over time or between groups. Among all variables, significant time by group interactions were observed in only N3 and non-REM alpha power. CONCLUSIONS: MBTI and sleep hygiene education had different effects on sleep macro and microarchitecture, suggesting that the underlying mechanisms of mindfulness training in improving sleep quality may differ from traditional interventions.

OBJECTIVE: To investigate the relationship between medication adherence, trust in physician and beliefs about medication among stroke survivors. To determine whether beliefs about medication would mediate the relationship between trust in physician and medication adherence. METHODS: A sample of 200 patients with a diagnosis of ischemic stroke or transient ischemic attack (TIA) completed a one-time survey, including the shortened Medication Adherence Report Scale (MARS-5), Beliefs about Medicines Questionnaire (BMQ), and Trust in Physician Scale (TIPS). RESULTS: Our study found that medication adherence was associated with trust in physician (p = 0.019) and four factors of beliefs about medication (BMQ1-Necessity: p < 0.001; BMQ2-Concerns: p = 0.024; BMQ3-Overuse: p = 0.016; BMQ4-Harm: p < 0.001). Furthermore, we found monthly income of survivors moderated the relationship between trust in physician and medication adherence (p = 0.007, CI(95%): [-0.822, -0.132]). CONCLUSIONS: The beliefs about medication mediating the relationship between trust in physician and medication adherence were different based on the stroke survivors' income bracket. PRACTICE IMPLICATIONS: Interventions being developed to improve medication adherence may benefit from improving stroke survivors' trust in physician and addressing their beliefs about medication. In addition, healthcare providers are advised to take monthly income into consideration to effectively address stroke survivors' concerns regarding prescribed medications to mitigate stroke recurrence.

OBJECTIVE: To investigate the relationships between beliefs about medication, trust in physician, self-efficacy, and medication adherence in severe asthma patients. METHODS: A sample of 117 patients with a diagnosis of Severe Asthma on Step 4 or 5 of GINA assessment of control treatment ladder completed a one-time survey, including the shortened Medication Adherence Report Scale (MARS-5), Beliefs about Medicines Questionnaire (BMQ), Trust in Physician Scale (TIPS), and Self-Efficacy in Taking Medication (SEAMS). RESULTS: Our study found that medication adherence was associated with trust in physician (p = 0.033); factor one of beliefs about medication - Necessity of taking medication (BMQ1-Necessity: p = 0.025); and two factors of self-efficacy in taking medication (SEAMS1-Difficulty: p = 0.001; SEAMS2-Uncertain: p = 0.005). Furthermore, two factors of self-efficacy and trust in physician together significantly mediated the relationship between beliefs about medication and medication adherence in a serial multiple mediator model. CONCLUSIONS: Beliefs about medication are fundamental in affecting asthma patients' trust in physician and self-efficacy, which in turn impact medication adherence. CLINICAL IMPLICATIONS: Interventions being developed to improve medication adherence may benefit from emphasizing on asthma patients' concerns about overuse and harm of medication. In addition, education program targeting to improve provider-patient relationship could help with patients' confidence in taking medication.

Burnout is an important occupational hazard and early detection is paramount in preventing negative sequelae in physicians, patients, and healthcare systems. Several screening tools have been developed to replace lengthy diagnostic tools for large-scale screening, however, comprehensive head-to-head evaluation for performance and accuracy are lacking. The primary objective of this study was to compare the diagnostic performance of five burnout screening tools, including a novel rapid burnout screening tool (RBST). This was a cross-sectional study involving 493 hospital staff (anaesthesiology and intensive care doctors, nurses, and ancillary staff) at the COVID-19 frontline across four hospitals in Singapore between December 2020 and April 2021. The Maslach Burnout Inventory-Human Services Survey (MBI-HSS) was used as the reference standard. Five burnout screening tools, the single-item MBI measure of burnout (SI-MBI), dual-item MBI (DI-MBI), abbreviated MBI (aMBI), Single Item Burnout Question (SIBOQ), and the RBST, were administered via a 36-item online survey. Tools were administered simultaneously and responses were anonymised. Burnout prevalence was 19.9%. The RBST and the SI-MBI had the two highest accuracies (87.8% and 81.9% respectively) and AUROC scores (0.86, 95% CI: 0.83-0.89 and 0.86, 95% CI: 0.82-0.89 respectively). However, the accuracy of the RBST was significantly higher than the SI-MBI (p < 0.0001), and it had the highest positive likelihood ratio (+LR = 7.59, 95% CI 5.65-10.21). Brief screening tools detect burnout albeit with a wide range of accuracy. This can strain support services and resources. The RBST is a free screening tool that can detect burnout with a high degree of accuracy.
ABSTRACT
There is great interest in crosstalk between the gastrointestinal and immune systems. Small intestinal bacterial overgrowth (SIBO) is a bowel disorder prevalent among patients with Parkinson's disease; SIBO treatment has been shown to modulate neurological inflammation, motor and cognitive outcomes there. However, to date, no link between Alzheimer's dementia and SIBO has been established. This pilot study sought to estimate the prevalence of SIBO in Alzheimer's dementia in the outpatient setting in Singapore General Hospital. It entailed performing a hydrogen breath test and objectively scoring gastrointestinal symptoms and their severity in 48 patients, comparing symptom scores and mean breath test values in those with mild to moderate Alzheimer's against age- and sex-matched controls that did not fulfill DSM-V criteria for probable Alzheimer's. Here, the prevalence of positive breath tests and symptoms of SIBO were no greater among Alzheimer's patients than in controls. This suggests that the gut microbiome changes and increased bowel inflammation seen in previous studies on Alzheimer's patients are likely effected through pathways other than SIBO, and are likely more complex than a mere increase in small bowel bacterial volume. Rather, future research could be directed along the lines of qualitative changes in small bowel microbiota, or pathologies in other parts of the gastrointestinal tract such as the colon or stomach, aspects which are not adequately captured by the hydrogen breath test. Keywords: Alzheimer's disease; dementia; gut-brain axis; small intestinal bacterial overgrowth; microbiome.

This study investigated the effectiveness of a psycho-behavioural intervention (PBI) for freezing of gait (FOG) management in people with Parkinson's disease, through a double-blind randomized controlled pilot trial conducted with nineteen participants. Though no significant between-group differences were found, PBI was feasible, well-tolerated by participants, and exhibited a trend towards improvement for FOG and depression, thereby warranting further longitudinal investigations.

BACKGROUND: In the COVID-19 pandemic, confidence in the government and access to accurate information have been critical to the control of outbreaks. Although outbreaks have emerged amongst communities of international migrant workers worldwide, little is known about how they perceive the government's response or their exposure to rumors. METHODS: Between 22 June to 11 October 2020, we surveyed 1011 low-waged migrant workers involved in dormitory outbreaks within Singapore. Participants reported their confidence in the government; whether they had heard, shared, or believed widely-disseminated COVID-19 rumors; and their socio-demographics. Logistic regression models were fitted to identify factors associated with confidence and rumor exposure. RESULTS: 1 in 2 participants (54.2%, 95% CI: 51.1-57.3%) reported that they believed at least one COVID-19 rumor. This incidence was higher than that observed in the general population for the host country (Singapore). Nonetheless, most participants (90.0%, 95% CI: 87.6-91.5%) reported being confident that the government could control the spread of COVID-19. Age was significantly associated with belief in rumors, while educational level was associated with confidence in government. CONCLUSIONS: Our findings suggest that language and cultural differences may limit the access that migrant workers have to official COVID-19 updates. Correspondingly, public health agencies should use targeted messaging strategies to promote health knowledge within migrant worker communities.
ABSTRACT
INTRODUCTION: Worldwide, COVID-19 clusters have emerged within communities of international migrant workers operating in high-density work and living environments. Despite their increased vulnerability, no study has documented the mental health burden of COVID-19 amongst these groups. To address this gap, we conducted a survey of migrant workers involved in large-scale dormitory outbreaks within Singapore. METHODS: Between 22 June to 11 October 2020, questionnaires were distributed to 1011 migrant workers undergoing extended movement restrictions. Mental health symptoms were measured using the 21-item Depression, Anxiety and Stress Scale (DASS-21). As covariates, we assessed participants' socio-demographics, quarantine status, COVID-19 health concerns, financial stability, and exposure to news and misinformation. Linear regression models were fitted to identify factors associated with DASS-21 scores. RESULTS: Complete movement restrictions were associated with increased depression and stress symptoms, while being diagnosed with COVID-19 was associated with increased anxiety. Participants who harboured fears about their health or job, perceived their health to be poorer, or had greater exposure to COVID-19 rumours reported higher depression, anxiety, and stress levels. Across the cohort, rates of severe or extremely severe depression (3.1%, 95% CI: 2.1-4.3%), anxiety (4.1%, 95% CI: 2.9-5.5%), and stress (1.3%, 95% CI: 0.7-2.2%) were similar to those observed in the general population for the host country (Singapore). CONCLUSIONS: As the first mental health survey of low-waged migrant workers during the pandemic, our findings provide a basis to identify and support at-risk individuals. This is critical as migrant workers often have limited access to healthcare services. At the same time, we documented resilience within the cohort as a whole.
ABSTRACT
BACKGROUND: Current pharmacological and behavioral treatment options for mild cognitive impairment (MCI) are limited, motivating a search for alternative therapies that might slow the progression of cognitive decline. OBJECTIVE: We investigated the effectiveness of a cognition-focused mindfulness-based intervention. METHODS: An open-label, three arm randomized controlled trial was conducted at a public tertiary medical center. Older persons (ages 45-75; Nâ=â76) diagnosed with MCI were recruited and randomized into either mindfulness-based training (MBT), cognitive rehabilitation therapy (CRT), or treatment as usual (TAU). Participants in the intervention arms received 8 weekly 2-h sessions delivered in a group setting and engaged in home practice. Primary outcomes measures included changes in index scores for attention, immediate memory, and delayed memory as measured using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). Depression was a secondary outcome. RESULTS: Using intent-to-treat analysis, we found that participants receiving MBT showed significant improvements in global cognition (dâ=â0.26; [95%CI 0.03-0.56]) and delayed memory (dâ=â0.36; [95%CI 0.17-0.57]), with significantly greater improvements in delayed memory than CRT (ηp2â=â0.10). However, there was no benefit of MBT over TAU. No change in depression was observed in the MBT group. Reductions in depression were associated with improvements in cognitive functioning in the MBT group only. CONCLUSION: Our results suggest that a cognition-focused MBT did not improve cognitive functioning in MCI patients substantially more than spontaneous reversion rates, possibly as mood symptoms were not significantly alleviated in this group.

ABSTRACT
Background: Mindfulness-based interventions may benefit healthcare professionals with burnout symptoms. Virtual reality (VR) may reduce initial difficulty of engaging in mindfulness exercises and increase participants' engagement through immersion and presence. Aim: The aim was to investigate how VR affects participants' experience of engagement with mindfulness practice, and its impact on quality of practice and negative mood states. Methods: Fifty-one healthcare professionals were randomized to receive either a visualization or non-visualization mindfulness practice, to compare the quality of practice through the use of audio only vs. with a virtual reality interface. Selected self-reported measures were collected during the session (immersion, quality and difficulty of practice, mood states and likelihood for future practice). Results: Results showed that order instead of type of modality administered made a difference in quality of mindfulness practice. A greater sense of presence was reported with VR if administered after audio (F = 4.810, p = 0.033, Partial η2 = 0.093). Further, participants described difficulty practicing with audio if administered after VR (F = 4.136, p = 0.048, Partial η2 = 0.081). Additionally, lower mood disturbance was reported with VR if administered after audio (F = 8.116, p = 0.006, Partial η2 = 0.147). Qualitative responses echoed a preference for VR to engage better, in addition to improved mood states after practice. Conclusion: Findings suggest that VR has the potential to provide healthcare professionals with an alternative or a supplement to conventional mindfulness practice.
