Impact of continued mindfulness practice on resilience and well-being in mindfulness-based intervention graduates during the COVID-19 pandemic: A cross-sectional study.

Aim: The coronavirus disease 2019 (COVID-19) pandemic has caused unprecedented stress. Mindfulness-based interventions (MBIs) are known to be effective in reducing stress. However, it is unclear how long-term outcomes differ between those who continue mindfulness practice after MBIs and those who do not. In this study, we hypothesized that those who continued mindfulness practice would have higher stress tolerance, and we examined this hypothesis through a survey of MBI graduates. In this study, we examined the association between the continuation of mindfulness practice among MBI completers and individual stress during the COVID-19 epidemic. Methods: A cross-sectional survey of MBI graduates was conducted. The physical and mental health states were compared between those who established a habit of mindfulness practice (practice group) and those who did not (no practice group). Results: The data were collected from 95 participants (response rate: 53.7%). Of the total respondents, 66 (69.5%) practiced mindfulness. Although the degree of perceived stress due to the COVID-19 pandemic was not statistically different between the practice and no practice groups, the practice group showed significantly lower levels of depression (p = 0.007), higher levels of resilience (p = 0.006), higher levels of overall health (p = 0.006), and higher levels of mental health (p = 0.039). The effect of mindfulness practice on reducing depression was fully mediated by resilience. Conclusion: Among MBI graduates, those who regularly practiced mindfulness had lower levels of depression and higher levels of physical and mental health. Thus, the continuation of mindfulness practice increases resilience, buffers against new stressors such as the COVID-19 pandemic, and has the potential to prevent depression.

Predictors and moderators of outcomes in mindfulness-based cognitive therapy intervention for early breast cancer patients.

OBJECTIVES: To deliver mindfulness-based cognitive therapy (MBCT) efficiently, the present study aimed (1) to identify predictors and moderators of patients who benefit from MBCT for psychological distress and (2) to explore the initial treatment reaction to identify the optimal number of sessions that produce a significant clinical effect. METHODS: This is the secondary analysis of a randomized controlled trial of MBCT for breast cancer patients (N = 74). We classified the participants into remitters vs. non-remitters, and responder vs. non-responders, according to the total score of the Hospital Anxiety and Depression Scale at the end of the intervention. We conducted multivariate analyses to explore for predictors of response and remission. We adopted generalized estimating equations to explore the optimal number of sessions. RESULTS: Sociodemographic and clinical backgrounds did not have significant influence on the treatment outcomes of the MBCT. Better program adherence, which was represented as the participants' better attendance to the MBCT program, was a significant predictor of both remission and response [odds ratio (OR) = 1.90, 95% confidence interval (CI) 1.25-2.89, p = 0.003, and OR = 1.72, 95% CI 1.12-2.65, p = 0.013, respectively]. It was not until seventh session that the remission rate exceeded 50% and the response rate showed significance. SIGNIFICANCE OF RESULTS: Sociodemographic and clinical characteristics did not significantly influence the treatment outcomes, while homework minutes and class attendance had significant effects on treatment outcomes. This implies that MBCT is recommended to any cancer patient, if he/she is motivated to the program, regardless of their sociodemographic and clinical characteristics. Patients are encouraged to attend a standard MBCT program (eight sessions) and do the assigned homework as intensely as possible. Further studies with larger sample and objective measurements are desired.

Effectiveness of Mindfulness-Based Cognitive Therapy With Follow-Up Sessions for Pharmacotherapy-Refractory Anxiety Disorders: Protocol for a Feasibility Randomized Controlled Trial.

BACKGROUND: Augmented mindfulness-based cognitive therapy (MBCT) with treatment as usual (mainly pharmacotherapy) is reported to be effective after treatment for anxiety disorders. However, whether its effectiveness persists in the long term is unclear. OBJECTIVE: This study aims to examine the feasibility, acceptability, and effectiveness of a follow-up program by conducting a feasibility randomized controlled trial (RCT) that compares augmented MBCT with follow-up sessions and that without follow-up sessions in preparation for a definitive RCT. METHODS: The study involves an 8-week MBCT with a 10-month follow-up. Patients aged 20 to 65 years who meet the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) criteria for panic disorder, agoraphobia, or social anxiety disorder, which is not remitted with usual treatment for at least 4 weeks, will be included in the study and randomly allocated to receive augmented MBCT with follow-up sessions or augmented MBCT without follow-up sessions. For this feasibility RCT, the primary outcomes are (1) study inclusion rate, (2) dropout rate, (3) attendance rate, and (4) mean and standard deviation of several clinical measures at 8 weeks and 5, 8, and 12 months. RESULTS: We started recruiting participants in January 2020, and 43 participants have been enrolled up to January 2021. The study is ongoing, and data collection will be completed by May 2022. CONCLUSIONS: This study is novel in terms of its design, which compares augmented MBCT with and without follow-up sessions. The limitations of the trial are as follows: (1) mixed participants in terms of the delivery mode of the intervention, and (2) lack of a pharmacotherapy-alone arm. Owing to its novelty and significance, this study will provide fruitful knowledge for future definitive RCTs.

A Long-Term Pilot Study of Mindfulness-Based Cognitive Therapy for Subjective Well-Being Among Healthy Individuals in Comparison with Clinical Samples.

PURPOSE: Mindfulness-based cognitive therapy (MBCT) could be an intervention for improving subjective well-being among healthy individuals (HIs). However, MBCT studies for HIs to improve their subjective well-being are rare. The aim of this study was to report the feasibility, safety and effectiveness of MBCT for HIs in comparison with clinical samples. PATIENTS AND METHODS: We conducted a single-arm, pre-post comparison pilot study offering MBCT to both HIs and people with common mental disorders. Twenty-four participants in total were included in the study. Eight weekly two-hour sessions with six monthly boosters were offered to all participants. Assessment was carried out at baseline, week 4, 8, and during follow-up. The 5-item World Health Organization Well-Being Index (WHO-5) was the primary clinical outcome measure. RESULTS: The results showed the MBCT is sufficiently safe and would be more feasible in HIs compared to in clinical samples (attendance rate: 81.5% vs 61.3%, p=0.06). Although Satisfaction with Life Scale, the other scale of subjective well-being used, improved significantly at week 20 (p=0.01), no significant improvement was seen in WHO-5. The results of the sub-group analysis revealed WHO-5 improved significantly at week 8 and 32 among the subjects whose baseline scores began in the lower half. CONCLUSION: MBCT is sufficiently safe and would be more feasible with HIs compared to the clinical samples. In designing randomized controlled trials, selecting HIs with lower subjective well-being would be reasonable to minimize the "ceiling effect" on outcomes.

Effectiveness of Mindfulness-Based Cognitive Therapy for Improving Subjective and Eudaimonic Well-Being in Healthy Individuals: A Randomized Controlled Trial.

Objectives: Better subjective and eudaimonic well-being fosters better health conditions. Several studies have confirmed that mindfulness-based interventions are effective for improving well-being; however, the samples examined in these studies have been limited to specific populations, and the studies only measured certain aspects of well-being rather than the entire construct. Additionally, few studies have examined the effect of mindfulness-based cognitive therapy on well-being. The present study examines the feasibility of mindfulness-based cognitive therapy and its effectiveness for improving subjective and eudaimonic well-being among community residents. Methods: The study design featured an 8-week randomized, waiting-list controlled, parallel-group study. 8 weekly mindfulness classes, followed by 2 monthly classes, were provided for healthy individuals aged 20-65 years who had a Satisfaction with Life Scale score of ≤ 24 indicating average to low cognitive aspect of subjective well-being. This trial was registered with the University Hospital Medical Information Network Clinical Trials Registry (ID: UMIN000031885, URL: https://upload.umin.ac.jp/cgi-open-bin/ctr_e/ctr_view.cgi?recptno=R000036376). Results: The results showed that cognitive aspect of subjective well-being and mindfulness skills were significantly improved at 8 weeks, and this effect was enhanced up to the end of the follow-up period. Positive affective aspect of subjective and eudaimonic well-being were significantly improved at 16 weeks. Conclusions: Eight weeks of mindfulness-based cognitive therapy with a 2-month follow-up period improves cognitive and affective aspects of subjective and eudaimonic well-being in healthy individuals. The order of improvement was cognitive, positive affective, and eudaimonic well-being. To verify these findings, multi-center randomized controlled trials with active control groups and longer follow-up periods are warranted.

Mindfulness-Based Cognitive Therapy for Psychological Distress, Fear of Cancer Recurrence, Fatigue, Spiritual Well-Being, and Quality of Life in Patients With Breast Cancer-A Randomized Controlled Trial.

CONTEXT: Mindfulness-based interventions have been receiving growing attention in cancer care. OBJECTIVES: The purpose of this randomized controlled trial is to examine the effectiveness of mindfulness-based cognitive therapy (MBCT) for psychological distress (anxiety and depression), fear of cancer recurrence (FCR), fatigue, spiritual well-being, and quality of life (QOL) in Japanese ambulatory patients with Stage I-III breast cancer. METHODS: A total of 74 patients were randomly assigned to either an eight-week MBCT intervention group (n = 38) or a wait-list control group (n = 36). The primary outcome was psychological distress, measured on Hospital Anxiety and Depression Scale. The secondary outcomes were FCR (Concerns About Recurrence Scale-overall anxiety subscale), fatigue (Brief Fatigue Inventory), spiritual well-being (Functional Assessment of Chronic Illness Therapy-Spiritual), QOL (Functional Assessment of Cancer Therapy-General), and mindfulness skills (Five Facet Mindfulness Questionnaire). The participants were assessed at baseline (T0), Week 8 (T1), and Week 12 (T2). The results were analyzed using a intention-to-treat linear mixed model. RESULTS: The participants in the MBCT group experienced significantly better outcomes in their psychological distress (Cohen's d = 1.17; P < 0.001), FCR (d = 0.43; P < 0.05), fatigue (d = 0.66; P < 0.01), spiritual well-being (d = 0.98; P < 0.001), and QOL (d = 0.79; P < 0.001) compared with the control group. The difference remained significant at T2 (four weeks after completion of the intervention). CONCLUSION: MBCT was demonstrated to improve well-being that encompasses psychological, physical, and spiritual domains in Japanese patients with nonmetastatic breast cancer. The favorable effect was maintained up to four weeks after the completion of the intervention.

Mindfulness-Based Cognitive Therapy for Improving Subjective Well-Being Among Healthy Individuals: Protocol for a Randomized Controlled Trial.

BACKGROUND: Previous studies have indicated that higher subjective well-being works as a protective factor for health. Some studies have already shown the effects of mindfulness-based interventions on improving subjective well-being. However, these studies targeted specific populations rather than the general public. Furthermore, they assessed either life evaluation or affective aspects of subjective well-being rather than the concept as a whole, including the eudemonic aspect of well-being. OBJECTIVE: This study aims to investigate the effectiveness and cost-effectiveness of mindfulness-based cognitive therapy (MBCT) for improving the wholistic aspects of subjective well-being in healthy individuals. METHODS: This study was an 8-week, randomized, parallel-group, superiority trial with a 2-month follow-up. Healthy individuals aged 20-65 years with scores lower than 25 on the Satisfaction With Life Scale (SWLS) were eligible to participate and randomly allocated to the MBCT group or the wait-list control group. The intervention program was developed by modifying an MBCT program to improve the well-being of a nonclinical population. The primary outcome was the difference between the two groups in mean change scores from the baseline on the SWLS. The secondary outcomes included scores on the Flourishing Scale and the Scale of Positive and Negative Experience as well as the incremental cost-effectiveness ratio. RESULTS: This study began recruiting participants in July 2018 and recruitment was completed at the end of September 2019. Data collection and dataset construction was completed by the end of March 2020. CONCLUSIONS: This study is unique in that it investigates MBCT's effects on the three different aspects of subjective well-being: life evaluation, affect, and eudemonia. It is limited, as the specific effect attributable to MBCT cannot be detected because of the lack of an active control group.

Effectiveness of mindfulness-based cognitive therapy in patients with anxiety disorders in secondary-care settings: A randomized controlled trial.

AIM: The primary objective of this study was to examine the effectiveness of mindfulness-based cognitive therapy (MBCT) in secondary-care settings where the vast majority of the patients have already undergone pharmacotherapy but have not remitted. METHODS: Eligible participants were aged between 20 and 75 years and met the criteria for panic disorder/agoraphobia or social anxiety disorder specified in the DSM-IV. They were randomly assigned to either the MBCT group (n = 20) or the wait-list control group (n = 20). The primary outcome was the difference in mean change scores between pre- and post-intervention assessments on the State-Trait Anxiety Inventory (STAI). The outcome was analyzed using an intent-to-treat approach and a mixed-effect model repeated measurement. RESULTS: We observed significant differences in mean change scores for the STAI State Anxiety subscale (difference, -10.1; 95% confidence interval, -16.9 to -3.2; P < 0.005) and STAI Trait Anxiety subscale (difference, -11.7; 95% confidence interval, -17.0 to -6.4; P < 0.001) between the MBCT and control groups. CONCLUSION: MBCT is effective in patients with anxiety disorders in secondary-care settings where the vast majority of patients are treatment-resistant to pharmacotherapy.

Feasibility study of mindfulness-based cognitive therapy for anxiety disorders in a Japanese setting.

OBJECTIVE: Mindfulness-based cognitive therapy (MBCT) could be a treatment option for anxiety disorders. Although its effectiveness under conditions of low pharmacotherapy rates has been demonstrated, its effectiveness under condition of high pharmacotherapy rate is still unknown. The aim of the study was to evaluate effectiveness of MBCT under the context of high pharmacotherapy rates. RESULTS: A single arm with pre-post comparison design was adopted. Those who had any diagnosis of anxiety disorders, between the ages of 20 and 74, were included. Participants attended 8 weekly 2-hour-long sessions followed by 2 monthly boosters. Evaluation was conducted at baseline, in the middle, at end of the intervention, and at follow-up. The State-Trait Anxiety Inventory (STAI)-state was set as the primary outcome. Pre-post analyses with mixed-effect models repeated measures were conducted. Fourteen patients were involved. The mean age was 45.0, and 71.4% were female. The mean change in the STAI-state at every point showed statistically significant improvement. The STAI-trait also showed improvement at a high significance level from the very early stages. The participants showed significant improvement at least one point in some other secondary outcomes. Trial registration Retrospectively registered at the University Hospital Medical Information Network on 1st August 2013 (ID: UMIN000011347).

Mindfulness-based cognitive therapy for Japanese breast cancer patients-a feasibility study.

OBJECTIVES: Mindfulness-based intervention has been receiving growing attention in cancer care. This study aimed to examine feasibility and to preliminary explore effectiveness of mindfulness-based cognitive therapy (MBCT) in Japanese breast cancer patients, and to explore possible modification of the program so that it fits better with this population. METHODS: Twelve participants with diagnosis of Stage I-III breast cancer received an eight session, weekly MBCT intervention in a group therapy format. The participants were followed up until 3 months after the completion of the program. RESULTS: All the participants completed the program with high attendance rate (mean number of attended sessions = 7.7). Significant improvement in anxiety (Hospital Anxiety and Depression Scale (HADS) - anxiety subscale; effect size Cohen's d = 0.88, P < 0.05), trauma-related psychological symptoms (Impact of Event Scale-revised; d = 0.64, P < 0.01) and quality of life (Functional Assessment of Cancer Therapy-Breast Cancer: FACT-B; d = 0.72, P < 0.01), and trend-level improvement in depression (HADS - depression subscale; d = 0.53, P = 0.054) were observed. Qualitative analyses suggested the program may be beneficial for alleviating fear of cancer recurrence and for increasing spiritual well-being. Some recommended modification of the program was indicated from the post-intervention interviews. CONCLUSIONS: Mindfulness-based cognitive therapy was well accepted by Japanese breast cancer patients and yielded favorable effect on their psychological status and quality of life. Further effectiveness study in a randomized-control design is warranted.

Unmet supportive needs of cancer patients in an acute care hospital in Japan--a census study.

PURPOSE: Little research has been done on supportive needs of cancer patients in acute hospitals in Japan. This study aims to comprehensively assess the unmet supportive needs of hospitalized cancer patients, as well as literacy and utilization of appropriate professional care. METHODS: All cancer patients (aged 20 to 80 years) who were hospitalized in a university hospital in Tokyo during the designated 3-day period between September 1 and October 31, 2007 were recruited for participation in the study. The M.D. Anderson Symptom Inventory, Brief Cancer-Related Worry Inventory, and Hospital Anxiety and Depression Scale were administered. Patients' knowledge and use of relevant services were evaluated. The results were compared with those of non-cancer patients in the same treatment settings. RESULTS: A total of 125 cancer patients and 59 non-cancer patients were enrolled. Cancer patients and non-cancer patients equally suffered from physical symptoms (15-26% had severe appetite loss, 18-19% had severe dry mouth, and 16-22% had severe pain); however, psychological distress of cancer patients exceeded that of non-cancer patients (28.0% vs 8.5%; p ≤ 0.05). Severe psychological distress was associated with severe worry about future prospects or interpersonal and social issues and presence of two or more severe symptoms. Two thirds of the patients with severe psychological distress knew about the psychiatric division, but only one third actually sought treatment. CONCLUSIONS: Needs related to psychological issues were more prevalent among cancer patients than among non-cancer patients, despite a similar level of physical distress. Special attention should be paid to cancer patients who worry over future prospects or interpersonal and social issues, and those who have two or more severe symptoms.
