An Uncontrolled Clinical Trial of Guided Respiration Mindfulness Therapy (GRMT) in the Treatment of Depression and Anxiety

Effects of Two Mindfulness Based Interventions on the Distinct Phases of the Stress Response Across Different Physiological Systems

When evaluating the effects of mindfulness-based interventions (MBIs) on the stress response, several aspects should be considered, such as 1) effects on various response systems, 2) temporal dynamics of the stress response, and 3) differences between programs. This study assesses the stress-attenuating effects of a standard mindfulness-based stress reduction (MBSR) and a second-generation MBI: MBSR with elements of other Buddhist practices (MBSR-B). Ninety-nine healthy volunteers were randomly assigned to the MBSR, MBSR-B, or waitlist control groups and their stress response was evaluated with the Trier Social Stress Test. Changes in the activity of the hypothalamic-pituitary-adrenal (HPA) axis, sympathoadrenomedullary system, the autonomic nervous system (ANS), and affect were measured during distinct phases of the task. Compared to waitlist control, the stress-attenuated effects of MBIs were detected across almost all systems and both negative and positive affect. In the parasympathetic branch of the ANS, the effect of MBIs was present in all stress phases (however, in the recovery phase, only MBSR-B has shown a statistically significant effect in comparison with the waitlist control). The stress-attenuating effects of MBIs were observed already in the anticipatory phase for cortisol, ANS, and negative affect (for negative affect, only the modified MBSR-B program has shown statistically significant effect in comparison with the waitlist control).

The association between major dietary patterns and severe mental disorders symptoms among a large sample of adults living in central Iran: Baseline data of YaHS-TAMYZ cohort study

Background

The diet’s role in developing psychological disorders has been considered by researchers in recent years.

Objective

To examine the association between major dietary patterns and severe mental disorders symptoms in a large sample of adults living in Yazd city, central Iran.

Methods

This cross-sectional study used the baseline data of a population-based cohort study (Yazd Health study: YaHS). Dietary intakes were assessed by a multiple-choice semi-quantitative food frequency questionnaire (FFQ, Yazd nutrition survey called TAMYZ). Psychological assessments were also done by using the depression, anxiety, and stress scale-21 (DASS-21) questionnaire. Major dietary patterns were identified using principal component analysis (PCA). Analysis of covariance (ANCOVA) and logistic regression analyses were used to evaluate the relationship between dietary patterns and mental disorders symptoms.

Results

A total of 7574 adults were included in the current analysis. Four major dietary patterns were identified: "Sugar and Fats”, “Processed Meats and Fish”, "Fruits" and “Vegetables and Red Meat”. After adjustment for all confounding variables, participants in the fifth quintile of “Fruits” dietary pattern which was highly correlated with dried fruits, canned fruits, fruit juice, olive, hydrogenated fats and fruits intake, had a lower odds of severe depression (OR=0.61, 95% CI: 0.45–0.81, p for trend=0.057), anxiety (OR=0.64, 95% CI: 0.50–0.80, p for trend=0.007), and stress, (OR=0.45, 95% CI: 0.30–0.68, p for trend=0.081).

Conclusions

The intake of a dietary pattern high in dried fruits, canned fruits, fruit juice, olive, hydrogenated fats, and fruits might be inversely associated with depression, anxiety, and stress symptoms. Future prospective studies are needed to warrant this finding.

The Relationship of Breathing and COVID-19 Anxiety When Using Smart Watches for Guided Respiration Practice: A Cross-Sectional Study

COVID-19 mortality rates are increasing worldwide, which has led to many highly restrictive precautionary measures and a strong sense of anxiety about the outbreak for many people around the world. There is thus an increasing concern about COVID-19 anxiety, resulting in recommending approaches for effective self-care. From a positive psychology perspective, it is also important for people to have positive affect when dealing with this pandemic. According to previous literature, respiration is considered to be an effective way to enhance people’s mental health. Among all the wearable devices, Apple Watch has the largest market share, so this study recruited Chinese users that use respiration exercise function on Apple Watch; a total of 316 valid data were retrieved. Meanwhile, to understand one approach related to using Apple Watch to practice respiration to reduce COVID-19 anxiety about being infected during the COVID-19 outbreak, this study used a web-based cross-sectional survey to examine anxiety about being infected by COVID-19 among Chinese people who had been using the Apple Watch to practice respiration during the period of the COVID-19 outbreak. The study was based on the Health Theoretical Model, and the model was developed with four dimensions and was validated with structural equation modeling. The results of this study showed that practicing few minutes had a positive relationship on positive attitude, and positive attitude had a negative relationship on pandemic anxiety and a positive relationship on continuance use intention. Anxiety about the pandemic had a negative relationship on the intention to continue using the function. This showed that respiration practice can help to suppress the increase in anxiety levels regarding this pandemic.

Evaluation of Guided Respiration Mindfulness Therapy (GRMT) for Reducing Stress in Nurses

Guided respiration mindfulness therapy (GRMT) is a clinical model of breathwork that has shown promise as a treatment for depression, anxiety, and stress. This study examined the effectiveness of GRMT as a holistically oriented intervention for reducing psychological distress in nurses. Sixty-two nurses were assigned to either five sessions of GRMT or 5 sessions of a mindfulness-based intervention (MBI) comparison condition which were conducted over 5 weeks. A no-treatment control was also included. Session-by-session change in depression, anxiety, and stress, along with change in mindfulness and self-compassion were assessed. Multilevel analysis showed GRMT resulted in statistically significant reductions in overall psychological distress, anxiety, and stress levels, as well as significant increases in mindfulness and self-compassion with large to very large effect sizes. On all measures, GRMT performed better than the comparison MBI intervention which showed no significant effect on stress levels. Results suggest that GRMT can provide nurses with an effective group intervention for reducing stress, and increasing mindfulness and self-compassion which are foundational elements of self-care for the holistic nurse.

Construct Validity of Outcome Rating Scale (ORS) Scores in Clinical Samples: Extension of Harris, Murphy, and Rakes' (2019) Narrative Review

PURPOSE

A recent review of 24 studies primarily evaluated psychometric properties of the Outcome Rating Scale (ORS) related to coefficient alpha and convergent validity.

METHOD

To provide a fuller picture, this review examined effect size (ES) estimates and the full range of correlations between ORS scores and related measures.

RESULTS

Mean ORS ESs equaled 1.00 for 44 comparison periods. ORS scores correlated highest with measures of depression and evidenced larger ESs in depression treatments.

DISCUSSION

The ORS functions as a robust measure for detecting client progress in clinical samples that were primarily young, female, and Caucasian. Some results suggest ORS scores primarily reflect a rapid response to interventions.

CONCLUSION AND LIMITATIONS

Future research should assess ORS scores' psychometric properties in response to interventions with more heterogeneous client samples as well as its capacity to monitor change beyond initial sessions.
