Intervention Design and Trial Protocol: Mindfulness-based Exposure for PAP-associated Claustrophobia.

Positive airway pressure (PAP) associated claustrophobia is common among obstructive sleep apnea patients and plays a prominent role in low adherence and treatment failure. As there are no evidence-based interventions for PAP-associated claustrophobia, the objective of the present research is to pilot test Mindfulness-based Exposure for PAP-associated Claustrophobia, in sleep apnea adults that present with treatment non-adherence and claustrophobia. This approach combines Mindfulness-based Stress Reduction with exposure-based treatment components to target this treatment-associated claustrophobia. The present article outlines the mindfulness exposure intervention design and methods and reports the pilot trial study protocol. Trial findings are intended to: (a) develop a preliminary effect size of the intervention on PAP-associated claustrophobia; (b) explore differences in treatment adherence by group (intervention vs control); and (c) establish feasibility for expanded protocol implementation, delivery, and participant acceptability of the intervention to support subsequent design of a fully powered randomized controlled trial.

The many facets of mindfulness and the prediction of change following mindfulness-based stress reduction (MBSR).

OBJECTIVES: Mindfulness-based stress reduction (MBSR) promotes numerous psychological benefits, but few studies have identified for whom MBSR is most effective. The current study tested the hypothesis that lower baseline mindfulness invites more "room to grow" and, thus, predicts greater improvement during MBSR. METHOD: We examined three facets of mindfulness (awareness, acceptance, decentering) among 131 MBSR participants prior to enrollment, to test the hypothesis that lower baseline mindfulness predicts greater improvements in perceived stress, positive affect (PA), and negative affect (NA) following MBSR. RESULTS: Lower acceptance and decentering predicted greater decreases in perceived stress. Higher awareness, acceptance, and decentering predicted greater increases in PA. Higher awareness predicted greater reductions in NA. Lower decentering predicted greater reductions in NA. CONCLUSION: Findings partly supported the hypothesis that lower baseline mindfulness predicts greater improvement following MBSR and emphasize the importance of assessing multiple mindfulness facets given their unique, contrasting relations to outcomes.

Dimensions of distress tolerance and the moderating effects on mindfulness-based stress reduction.

BACKGROUND AND OBJECTIVES: This study examined the relationship between distress tolerance and psychosocial changes among individuals participating in Mindfulness-Based Stress Reduction (MBSR). The objective of the analysis was to discern whether individuals with lower distress tolerance measured before MBSR showed larger reductions in perceived stress following MBSR. DESIGN AND METHODS: Data were collected from a sample of convenience (n = 372) using a quasi-experimental design. Participants completed self-report measures immediately prior to course enrollment and following course completion. RESULTS: Perceived stress, distress tolerance, and mood states showed favorable changes from pre- to post-MBSR in the current study. Baseline distress tolerance significantly moderated reductions on perceived stress, supporting the primary hypothesis that individuals with lower baseline distress tolerance evidenced a greater decline in perceived stress following MBSR. For a one-unit increase on the self-reported baseline Distress Tolerance Scale, reported perceived stress scores decreased by 2.5 units (p < .0001). CONCLUSIONS: The finding that individuals with lower baseline distress tolerance evidenced a greater decline in perceived stress may offer hints about who is most likely to benefit from MBSR and other mindfulness-based treatments. Identifying moderators of treatment outcomes may yield important benefits in matching individuals to treatments that are most likely to work for them.

Effective and viable mind-body stress reduction in the workplace: a randomized controlled trial.

Highly stressed employees are subject to greater health risks, increased cost, and productivity losses than those with normal stress levels. To address this issue in an evidence-based manner, worksite stress management programs must be able to engage individuals as well as capture data on stress, health indices, work productivity, and health care costs. In this randomized controlled pilot, our primary objective was to evaluate the viability and proof of concept for two mind-body workplace stress reduction programs (one therapeutic yoga-based and the other mindfulness-based), in order to set the stage for larger cost-effectiveness trials. A second objective was to evaluate 2 delivery venues of the mindfulness-based intervention (online vs. in-person). Intention-to-treat principles and 2 (pre and post) × 3 (group) repeated-measures analysis of covariance procedures examined group differences over time on perceived stress and secondary measures to clarify which variables to include in future studies: sleep quality, mood, pain levels, work productivity, mindfulness, blood pressure, breathing rate, and heart rate variability (a measure of autonomic balance). Two hundred and thirty-nine employee volunteers were randomized into a therapeutic yoga worksite stress reduction program, 1 of 2 mindfulness-based programs, or a control group that participated only in assessment. Compared with the control group, the mind-body interventions showed significantly greater improvements on perceived stress, sleep quality, and the heart rhythm coherence ratio of heart rate variability. The two delivery venues for the mindfulness program produced basically equivalent results. Both the mindfulness-based and therapeutic yoga programs may provide viable and effective interventions to target high stress levels, sleep quality, and autonomic balance in employees.

Mindfulness Based Stress Reduction: effect on emotional distress in diabetes.

Psychological distress is common in patients with diabetes. Little is known about the impact of Mindfulness Based Stress Reduction (MBSR), a non-traditional, cognitive behavioural intervention designed to improve stress management skills, in patients with diabetes. The purpose of this retrospective analysis was to evaluate the impact of MBSR training on mood states in 25 individuals with diabetes. All participants completed the Profile of Mood States Short Form (POMS-SF) at baseline and following eight weeks of MBSR. Overall psychological distress measured by the total mood score (TMS) and six subscales - including tension/anxiety, depression/dejection, anger/hostility, fatigue/inertia, confusion/bewilderment and vigour/activity - were assessed. Overall mood, measured by the TMS, as well as all subscale mood measurements improved significantly from baseline following MBSR training. Compared to population means, those with diabetes had higher distress at baseline and similar levels of distress following MBSR training. The primary reason participants reported for enrolling in the MBSR course was to improve stress management skills. It was concluded that MBSR training is a promising, group-based intervention that can be used to decrease psychological distress in individuals with diabetes who perceive a need for training in stress management.

Mindfulness training modifies subsystems of attention.

Mindfulness is defined as paying attention in the present moment. We investigate the hypothesis that mindfulness training may alter or enhance specific aspects of attention. We examined three functionally and neuroanatomically distinct but overlapping attentional subsystems: alerting, orienting, and conflict monitoring. Functioning of each subsystem was indexed by performance on the Attention Network Test. Two types of mindfulness training (MT) programs were examined, and behavioral testing was conducted on participants before (Time 1) and after (Time 2) training. One training group consisted of individuals naive to mindfulness techniques who participated in an 8-week mindfulness-based stress reduction (MBSR) course that emphasized the development of concentrative meditation skills. The other training group consisted of individuals experienced in concentrative meditation techniques who participated in a 1-month intensive mindfulness retreat. Performance of these groups was compared with that of control participants who were meditation naive and received no MT. At Time 1, the participants in the retreat group demonstrated improved conflict monitoring performance relative to those in the MBSR and control groups. At Time 2, the participants in the MBSR course demonstrated significantly improved orienting in comparison with the control and retreat participants. In contrast, the participants in the retreat group demonstrated altered performance on the alerting component, with improvements in exogenous stimulus detection in comparison with the control and MBSR participants. The groups did not differ in conflict monitoring performance at Time 2. These results suggest that mindfulness training may improve attention-related behavioral responses by enhancing functioning of specific subcomponents of attention. Whereas participation in the MBSR course improved the ability to endogenously orient attention, retreat participation appeared to allow for the development and emergence of receptive attentional skills, which improved exogenous alerting-related process.

Variation of mood and empathy during internship.

CONTEXT: Internship is a time of great transition, during which mood disturbances are common. However, variations in mood and empathy levels throughout the internship year have not been investigated. OBJECTIVE: To examine mood patterns and changes in empathy among internal medicine residents over the course of the internship year. DESIGN: Cohort study of interns involving completion of survey instruments at 4 points: time 1 (June 2000; Profile of Mood States [POMS] and Interpersonal Reactivity Index [IRI]), times 2 and 3 (November 2000 and February 2001; POMS), and time 4 (June 2001; POMS and IRI). SETTING: Internal medicine residency program at a university-based medical center. PARTICIPANTS: Sixty-one interns. MAIN OUTCOME MEASURES: Baseline scores of mood states and empathy; trends in mood states and empathy over the internship year. RESULTS: Response rates for time 1 were 98%; for time 2, 72%; for time 3, 79%; and for time 4, 79%. Results of the POMS revealed that physicians starting their internship exhibit less tension, depression, anger, fatigue, and confusion and have more vigor than general adult and college student populations (P<.001 for all). Results of the IRI showed better baseline scores for perspective taking (P<.001) and empathic concern (P =.007) and lower scores for personal distress (P<.001) among interns compared with norms. Five months into internship, however, POMS scores revealed significant increases in the depression-dejection (P<.001), anger-hostility (P<.001), and fatigue-inertia (P<.001) scales, as well as an increase in IRI personal distress level (P<.001). These increases corresponded with decreases in the POMS vigor-activity scores (P<.001) and IRI empathic concern measures (P =.005). Changes persisted throughout the internship period. CONCLUSIONS: We found that, in this sample, enthusiasm at the beginning of internship soon gave way to depression, anger, and fatigue. Future research should be aimed at determining whether these changes persist beyond internship.
