Brain activity during meditation in first-time meditators.

AIM OF THE STUDY: The electrophysiological correlates of meditation states in both short and long-term meditators have been increasingly documented; however, little is known about the brain activity associated with first-time meditation experiences. The goal of this study was to investigate the electrophysiological correlates of a single guided mindfulness meditation session in subjects with no previous meditation experience. MATERIALS AND METHODS: We analyzed electroencephalogram (EEG) changes in signal power, hemispheric asymmetry, and information flow between EEG channels, in 16 healthy subjects who were new to meditation practice. RESULTS: Our results show that information flow decreases in the theta (4-8 Hz) and alpha ranges (8-13 Hz) during mindfulness meditation exercise as compared to control: a passive listening condition. These changes are accompanied by a general trend in the decrease of alpha power over the whole scalp. One possible interpretation of these results is that there is an increased level of alertness/vigilance associated with the meditation task rather than reaching the target state. CONCLUSIONS: Our study expands on the existing body of knowledge concerning neural oscillations during breathing meditation practice by showing that in participants with no previous meditation training, EEG correlates are different from the electrophysiological signatures of mindfulness meditation found in studies of more advanced practitioners.

Assessment of Neurocognitive Functions, Olfaction, Taste, Mental, and Psychosocial Health in COVID-19 in Adults: Recommendations for Harmonization of Research and Implications for Clinical Practice.

OBJECTIVE: To propose a set of internationally harmonized procedures and methods for assessing neurocognitive functions, smell, taste, mental, and psychosocial health, and other factors in adults formally diagnosed with COVID-19 (confirmed as SARS-CoV-2 + WHO definition). METHODS: We formed an international and cross-disciplinary NeuroCOVID Neuropsychology Taskforce in April 2020. Seven criteria were used to guide the selection of the recommendations' methods and procedures: (i) Relevance to all COVID-19 illness stages and longitudinal study design; (ii) Standard, cross-culturally valid or widely available instruments; (iii) Coverage of both direct and indirect causes of COVID-19-associated neurological and psychiatric symptoms; (iv) Control of factors specifically pertinent to COVID-19 that may affect neuropsychological performance; (v) Flexibility of administration (telehealth, computerized, remote/online, face to face); (vi) Harmonization for facilitating international research; (vii) Ease of translation to clinical practice. RESULTS: The three proposed levels of harmonization include a screening strategy with telehealth option, a medium-size computerized assessment with an online/remote option, and a comprehensive evaluation with flexible administration. The context in which each harmonization level might be used is described. Issues of assessment timelines, guidance for home/remote assessment to support data fidelity and telehealth considerations, cross-cultural adequacy, norms, and impairment definitions are also described. CONCLUSIONS: The proposed recommendations provide rationale and methodological guidance for neuropsychological research studies and clinical assessment in adults with COVID-19. We expect that the use of the recommendations will facilitate data harmonization and global research. Research implementing the recommendations will be crucial to determine their acceptability, usability, and validity.

Generalized anxiety and depressive symptoms in various age groups during the COVID-19 lockdown in Poland. Specific predictors and differences in symptoms severity.

BACKGROUND: Previous studies carried out in different countries have indicated that young adults experienced higher levels of emotional distress, in the form of depressive and anxiety symptoms, than older age groups during the COVID-19 pandemic. However, little is known about which pandemic-related difficulties and factors may contribute to these forms of emotional distress in various age groups. PURPOSE: The aim of the current study was to investigate: (i) differences in levels of depressive and generalized anxiety symptoms in four age groups in the Polish population during the COVID-19 lockdown; (ii) differences in perceived difficulties related to the pandemic in these groups; and (iii) which factors and difficulties related to the pandemic are the best predictors of generalized anxiety and depressive symptoms in various age groups during the COVID-19 lockdown. METHOD: A total of 1115 participants (aged 18-85) took part in the study. The sample was representative of the Polish population in terms of sex, age, and place of residence. Participants completed the following online: the Patient Health Questionnaire-9, the Generalized Anxiety Disorder-7, a Scale of Perceived Health and Life Risk of COVID-19, a Social Support Scale, and a Scale of Pandemic-Related Difficulties. RESULTS: Younger age groups (18-29 and 30-44) experienced higher levels of depressive and generalized anxiety symptoms than older adults (45-59 and 60-85 years). Household relationship difficulties were among the most significant predictors of depressive and generalized anxiety symptoms in all age groups. Fear and uncertainty related to the spread of the virus was one of the most important predictors of emotional distress in all the groups apart from the adults between 18 and 29 years, whereas difficulties related to external restrictions were one of the most significant predictors of depressive and anxiety symptoms exclusively in the youngest group. CONCLUSIONS: The youngest adults and those experiencing difficulties in relationships among household members are the most vulnerable to depressive and generalized anxiety symptoms during the COVID-19 lockdown. It is important to plan preventive and therapeutic interventions to support these at-risk individuals in dealing with the various challenges related to the COVID-19 pandemic.

Mindfulness-based cognitive therapy reduces clinical symptoms, but do not change frontal alpha asymmetry in people with major depression disorder.

OBJECTIVES: Mindfulness-based cognitive therapy (MBCT) has demonstrated to be successful in the reduction of relapse rates in patients with recurrent major depressive disorder (MDD). Little is known if MBCT is effective for treating individuals with current MDD episode and about underlying psychophysiological mechanisms of symptoms reduction. The aim of the present study was to assess effects of MBCT on depressed individuals in terms of reduction of depressive and anxiety symptoms and to evaluate if this therapeutic improvement would be reflected on neurophysiological level by shift in frontal alpha asymmetry (FAA). PARTICIPANTS: We studied 20 individuals with current MDD. DESIGN: Participants were randomly assigned either to waiting list or 8-week MBCT. Before and after the treatment we have assessed depression, anxiety, and FAA in resting-state electroencephalogram (EEG) - an indicator of approach vs. withdrawal-related response dispositions and a vulnerability factor of MDD. RESULTS: In line with previous findings, reduction of depressive and anxiety symptoms, but no change in mean values of FAA in MBCT group was found. CONCLUSIONS: These results provide a support for the beneficial effects of MBCT in current MDD treatment, however, they do not support the hypothesis on alpha asymmetry change as a neural correlate of MDD improvement.

Manifestations of clinical depression in daily life: a daily diary study of descriptions of naturally occurring events.

In the present study, clinically depressed (n = 135) and non-depressed adults (n = 138) described the events that happened to them each day for two weeks, and these descriptions were content analysed. Participants also rated how stressful and how positive each event was. Multilevel analyses found that depressed individuals, compared to the non-depressed, used more negative emotion words and more pronouns and used fewer positive emotion words, and they rated events as more stressful and less positive. Stressfulness of events was positively related to the use of pronouns and negative emotion words and was negatively related to the use of positive emotion words. Relationships between positivity of events and word counts were in the opposite direction. Controlling for stressfulness or positivity of events eliminated differences between the depressed and non-depressed in word use, except for use of other-pronouns words. Compared to the non-depressed, depressed people may either experience a greater number of objectively stressful or less pleasant daily events or perceive naturally occurring daily events as more stressful and less positive, and they describe daily events in ways that are consistent with such differences.

Attention to negative words predicts daily rumination among people with clinical depression: evidence from an eye tracking and daily diary study.

The present study examined relationships between attention to negative words and daily rumination and daily adjustment in a sample of clinically depressed individuals. We recorded eye movements of 43 individuals diagnosed with major depression while they were freely viewing dysphoric, threat-related, neutral, and positive words. Then, each day for one week, participants provided measures of their daily rumination and psychological adjustment. Multilevel analyses found that attention to dysphoric and threat-related words was positively related to daily rumination and attention to threat-related words was negatively related to daily adjustment. These findings suggest that the impaired ability to disengage from negative words is positively related to rumination in daily life and is negatively related to well-being, as defined in terms of Beck's Triad.

Positive online attentional training as a means of modifying attentional and interpretational biases among the clinically depressed: An experimental study using eye tracking.

OBJECTIVE: The present study examined the effectiveness of online positive attention bias modification training (ABMT) in inducing positive attention and positive interpretational biases in depressed individuals. METHOD: Clinically depressed individuals (n = 60) were randomly assigned to one of two conditions of 14-day online ABMT. In the positive ABMT condition, a probe replaced positive stimuli in 100% of trials. In the control condition, the probe replaced positive stimuli in 50% of trials. Before and after training, we recorded eye movements during the completion of a Scrambled Sentence Task in which participants created positive or negative sentences. Participants also completed measures of symptoms of depression and anxiety. RESULTS: After training, participants in the positive ABMT condition fixated longer on positive keywords than participants in the control group and experienced a significant reduction in anxiety. CONCLUSION: These findings suggest that positive AMBT can promote positive attention bias among clinically depressed individuals.

[Psychosocial working conditions and major depression or depressive disorders: Review of studies]. / Psychospoleczne warunki pracy a depresja i zaburzenia depresyjne: przeglad badan.

In the paper the review of studies on the relationship between clinically and subjectively diagnosed depression and psychosocial working conditions has been conducted. Most of these studies include mobbing and stress at work. A large part of them also points to organizational injustice and restructuring, and single studies - long working hours, and work-life imbalance as potential causes of both depression and depressive disorders among working people. The results of these studies confirm that in particular mobbing and stress at work are associated with an increased risk of mental health problems. The greater the exposure to these factors is, the higher the risk of depression is. It has also been shown in many studies that these associations are stronger amongst women. The results of these studies clearly show the need to make every possible effort to change such working environments, and preferably - to prevent their deterioration in the short term.

Metacognitive model of mindfulness.

Mindfulness training has proven to be an efficacious therapeutic tool for a variety of clinical and nonclinical health problems and a booster of well-being. In this paper we propose a multi-level metacognitive model of mindfulness. We postulate and discuss following hypothesis: (1) mindfulness is related to the highest level of metacognition; (2) mindfulness depends on dynamic cooperation of three main components of the metacognition (metacognitive knowledge, metacognitive experiences and metacognitive skills); (3) a mindful meta-level is always conscious while the other meta-cognitive processes can occur implicitly; (4) intentionally practiced mindfulness decreases dissociations between awareness and meta-awareness; (5) components of mindful meta-level develop and change during continuous practice. The current model is discussed in the light of empirical data and other theoretical approaches to mindfulness concept. We believe that presented model provides some helpful avenues for future research and theoretical investigations into mindfulness and the mechanisms of its actions.

Does the control of negative emotions influence blood pressure control and its variability?

The aim was to assess the control of negative emotions in treated patients with hypertension in comparison with normotensive individuals and to evaluate the association between suppression of negative emotions, control of blood pressure (BP) on ambulatory blood pressure monitoring (ABPM) and blood pressure variability (BPV). We studied 195 patients (women/men: 89/106); mean age 45.4 ± 15.9 years. All patients had ABPM and completed the Courtauld Emotional Control Scale (CECS). The total CECS score and scores for subscales for anger, depression and anxiety were analyzed together with mean BP values from ABPM, and their SD and coefficient of variation as BPV measures. The mean CECS score was 54 ± 12 in all subjects; highest in uncontrolled hypertension 56 ± 11, intermediate 53 ± 12 in controlled hypertension and lowest 48 ± 12 in normotensive subjects. The reference value for the Polish population is 50 ± 11. Significant differences of mean CECS scores among groups were observed (p = 0.0165) also in multivariate analysis. The difference between uncontrolled hypertension and normotension was significant (p = 0.0262). Few significant, weak correlations were observed between CECS score or its subscales and ABPM derivates in all subjects. Conclusion. Suppression of negative emotions may adversely affect BP control in treated hypertensive patients and it should be considered a cause of uncontrolled hypertension.

Validation of the Brief Experiential Avoidance Questionnaire (BEAQ) in a representative Polish sample. / Walidacja Krótkiego kwestionariusza unikania doswiadczania (BEAQ) w reprezentatywnej grupie Polaków i Polek.

OBJECTIVES: The study aimed to validate the Brief Experiential Avoidance Questionnaire (BEAQ) in Polish and establish its psychometric properties. METHODS: A representative sample of the Polish population (N = 1,216) in terms of gender, age, education, and place of residence participated in the online study. The adaptation was conducted with back translation to preserve fidelity to the original version. Apart from BEAQ, participants filled in questionnaires measuring the levels of depression, cognitive fusion, mindfulness and psychological flexibility. RESULTS: Confirmatory factor analysis showed that the unidimensional model insufficiently fit the data, similarly to other reports on BEAQ validations. Exploratory factor analysis using oblimin rotation extracted two factors labeled "cognitive-emotional avoidance" and "behavioral avoidance" with internal consistency (α) of 0.78 and 0.74, respectively, and stability over time of r = 0.79 and 0.75 in a 21-day test-retest measurement. The subscales demonstrated satisfactory convergent and discriminant validity. CONCLUSIONS: The Polish BEAQ validation demonstrates it is a tool that can be successfully used in research and clinical practice as it provides a reliable measure of experiential avoidance and is convenient thanks to its limited duration.

Factors associated with prolonged COVID-related PTSD-like symptoms among adults diagnosed with mild COVID-19 in Poland.

COVID-19 has been considered a possible cause of post-traumatic stress disorder (PTSD) or similar conditions. However, what specific disease symptoms may contribute most to prolonged PTSD-like symptoms in COVID-19 survivors is unclear. The study aimed to present the factor structure of COVID-19 symptoms and identify which symptoms of COVID-19 best explain the subsequent presence of PTSD-like symptoms in mild COVID-19 survivors. COVID-positive adults (n = 341) completed online self-report scales at the baseline assessment (T1) and after approximately 4 months (T2), including The Patient Health Questionnaire Anxiety-Depression Scale; The Scale of Psychosocial Experience Related to COVID-19, The Primary Care PTSD Screen for DSM-5; and self-designed questionnaires evaluating the severity of COVID-related medical and neurocognitive symptoms and pre-pandemic variables. Exploratory factor analysis revealed five factors of COVID-19 symptoms: flu-like, respiratory, cold, neurological, and neurocognitive. Hierarchical logistic regression showed that besides selected control variables (anxiety and depression, presence of PTSD-like symptoms, COVID-related stigma in T1), neurocognitive symptoms of COVID-19 in T1 but not other symptoms of the disease were a significant predictor of the presence of PTSD-like symptom in T2. Findings suggest a need for a comprehensive neurocognitive assessment of people diagnosed with COVID-19 and prompt interventions targeting the prevention of potential risks for long-term PTSD-like states at the community level.

A cognitive perspective on mindfulness.

Mindfulness, the core teaching of the Buddhist tradition, has been receiving serious attention from the West in recent decades as evidence of the efficacy of mindfulness-based interventions for emotional distress have become available. Although traditional Buddhist texts have described the mechanisms of mindfulness and the way to cultivate it in great detail, much is still not known from the perspective of Western science. In particular, there is no general agreement on the conceptualization and operationalization of mindfulness. Several conceptual models of mindfulness (referred to as "state" or "trait") have been put forward to elucidate different aspects of this phenomenon, but none has gained sufficient empirical validation. This article proposes a new cognitive model of mindfulness. It has been our goal to describe and interrelate a relatively comprehensive group of determinants of a state of mindfulness, the consequences of its regular practicing, the mechanisms responsible for its beneficial effects, and the feedback mechanisms operating between the various constituents of the model. Within this model, the primary emphasis has been placed on understanding the cognitive processes shaping a state of mindfulness (i.e., the links between consciousness, meta-awareness and the unconscious), and on their determinants (i.e., the executive functions of attention and the components of working memory). A metacognitive system promoting mindfulness, as well as the general capability of the central executive system, is suggested as a factor explaining individual differences in mindfulness, whereas decentering, self-compassion, and reduction of self-focused attention are proposed as mechanisms mediating beneficial changes. We hope that the model presented will encourage further discussion and orient future studies in the area of mindfulness.

[Polish adaptation and validation of the Agoraphobic Cognitions Questionnaire and the Body Sensations Questionnaire]. / Polska adaptacja i walidacja Kwestionariusza Mysli Towarzyszacych Agorafobii (KMTA) oraz Kwestionariusza Doznan Cielesnych (KDC).

AIM: The present study aimed at the adaptation and validation of two questionnaires assessing fear of bodily sensations (BSQ; suggested Polish name: Kwestionariusz Doznan Cielesnych [KDC]) and concerns specific to agoraphobics (ACQ; suggested Polish name: Kwestionariusz Mysli Towarzyszacych Agorafobii [KMTA]). METHOD: The study included a total of 82 patients diagnosed with agoraphobia or panic disorder with agoraphobia according to the diagnostic criteria of the DSM-IV as well as 100 control subjects who did not show the presence of mental disorders. RESULTS: The results showed that both adapted questionnaires meet basic psychometric criteria. The Polish-language versions of the ACQ and BSQ are characterized by a high content validity, internal consistency and showed to be stable over a period of 28 days. Moreover, the factor structure of the Polish version of the ACQ showed to be highly similar to the original version. CONCLUSIONS: Polish-language versions of the ACQ and BSQ have been found to be reliable and valid research and diagnostic instruments for the assessment of fear for bodily sensations and agoraphobic cognitions. Due to their high efficiency and adequate psychometric characteristics these measures might be very useful in research as well as in the diagnosis and evaluation of therapeutic effects.

Mindfulness meditation and psychedelics: potential synergies and commonalities.

There has been increasing scientific and clinical interest in studying psychedelic and meditation-based interventions in recent years, both in the context of improving mental health and as tools for understanding the mind. Several authors suggest neurophysiological and phenomenological parallels and overlaps between psychedelic and meditative states and suggest synergistic effects of both methods. Both psychedelic-assisted therapy and meditation training in the form of mindfulness-based interventions have been experimentally validated with moderate to large effects as alternative treatments for a variety of mental health problems, including depression, addictions, and anxiety disorders. Both demonstrated significant post-acute and long-term decreases in clinical symptoms and enhancements in well-being in healthy participants, in addition. Postulated shared salutogenic mechanisms, include, among others the ability to alter self-consciousness, present-moment awareness and antidepressant action via corresponding neuromodulatory effects. These shared mechanisms between mindfulness training and psychedelic intervention have led to scientists theorizing, and recently demonstrating, positive synergistic effects when both are used in combination. Research findings suggest that these two approaches can complement each other, enhancing the positive effects of both interventions. However, more theoretical accounts and methodologically sound research are needed before they can be extended into clinical practice. The current review aims to discuss the theoretical rationale of combining psychedelics with mindfulness training, including the predictive coding framework as well as research findings regarding synergies and commonalities between mindfulness training and psychedelic intervention. In addition, suggestions how to combine the two modalities are provided.

Coping styles with stress and its relations to psychiatric and clinical symptoms in patients with sarcoidosis: A latent profile analysis.

OBJECTIVE: Although stress and styles of coping with it can have a major impact on one's health and can determine the course and management of chronic diseases, no previous studies have evaluated coping strategies and their relation to emotional distress and clinical symptoms in sarcoidosis. METHODS: In two consecutive studies, we investigated differences in coping styles of sarcoidosis patients in comparison to healthy control subjects and the association of identified profiles to an objective measurement of disease (Forced Vital Capacity) and symptoms such as dyspnoea, pain, anxiety and depressive symptoms in 36 patients with sarcoidosis (study 1) and 93 patients with sarcoidosis (study 2). RESULTS: Across two studies we found that patients with sarcoidosis used emotion-focused and avoidant coping significantly less often than healthy individuals, and that in both groups the profile with dominant problem (task)-focus style was the most beneficial in terms of mental health. Further, the profile of sarcoidosis patients characterized by the lowest intensity of all coping strategies was found to be superior in terms of physical health status (dyspnoe, pain and FVC level). CONCLUSION: These findings suggest that successful management of sarcoidosis should include coping styles assessment and call for a multidisciplinary approach in diagnosis and treatment of sarcoidosis patients.

Collective action mitigates the negative effects of COVID-19 threat and anti-abortion restrictions on mental health.

BACKGROUND: The COVID-19 pandemic changed our lives in many different domains, forcing people to adapt to countrywide lockdowns, school shutdowns, and business closures. The burden of the COVID-19 pandemic resulted also in deterioration of mental health. At the same time, political conflicts and social inequalities was reinforced and many people engaged in demonstrations to fight for their rights. This study examines whether collective acting for an important cause during the pandemic might mitigate the impact of both political tension related to anti-abortion restrictions and COVID-19 threats on mental health. METHODS: We conducted a two-wave study with a representative sample of the Polish population, investigating the effect of participating in Polish pro-choice demonstrations on depressive and anxiety symptoms. RESULTS: Participating in protests attenuated the negative effects of COVID-19 threat and anti-abortion restrictions on mental health. Moreover, we found that the feeling of solidarity with other demonstrators and sense of agency derived from such demonstrations led to lower levels of depressive and anxiety symptoms. CONCLUSION: The results of the study indicate that participating in meaningful and value-oriented collective action may serve as a buffer against the detrimental effects of social and health threats.

Exposure to self-reported traumatic events and probable PTSD in a national sample of Poles: Why does Poland's PTSD prevalence differ from other national estimates?

BACKGROUND: There is a lack of studies on trauma exposure and PTSD prevalence in Poland on representative samples. Available data from studies on convenient samples show very high rates of probable PTSD compared with relevant estimates in other countries. OBJECTIVE: This study aimed to measure the exposure to self-report traumatic events (PTEs) and to estimate the current rate of prevalence of probable posttraumatic stress disorder (PTSD) in accordance with DSM-5 criteria in a population-based sample of Poles. Additionally, the link between PTSD intensity and level of life satisfaction was investigated. METHOD: A representative sample of 1,598 adult Poles was recruited. Probable PTSD was assessed with the Posttraumatic Diagnostic Scale for DSM-5 (PDS-5) and the Satisfaction with Life Scale (SWLS) was also used. RESULTS: The findings showed that 60.3% of Poles had experienced at least one PTE and 31.1% of those who had been exposed to trauma reported symptoms of PTSD. At the level of the entire sample, the obtained rate for probable PTSD was 18.8%. The traumatic events with the highest probabilities of PTSD symptoms were child abuse and sexual assault. Levels of life satisfaction were significantly lower in the group of participants with probable PTSD. CONCLUSIONS: We found that the current prevalence of probable PTSD in Poland is intriguingly high relative to rates reported in comparable representative samples from other countries across the world. Possible mechanisms are discussed, including a lack of social acknowledgement of WWII and other traumas as well as poor access to trauma-focused care. We hope that this research may inspire more studies investigating cross-national differences in PTSD and trauma exposure.

Long-lasting effects of World War II trauma on PTSD symptoms and embodiment levels in a national sample of Poles.

The main aim of this study was to investigate the long-lasting influences of World War II (WWII) trauma in a national sample of Poles, based on Danieli's (1998) survivors' post-trauma adaptational styles (fighter, numb, victim) and their link with current post-traumatic stress disorder (PTSD) symptoms and embodiment level among participants. We also sought to investigate whether the level of knowledge about WWII trauma among ancestors could moderate that association. The study was conducted among a representative sample of 1598 adult Poles obtained from an external company. Participants filled out the Danieli Inventory of Multigenerational Legacies of Trauma, the knowledge about traumatic World War II experiences in the family questionnaire, the Posttraumatic Diagnostic Scale-5, and the Experience of Embodiment Scale. We observed a positive relationship between all survivors' post-trauma adaptational styles and current levels of PTSD symptoms among participants. In addition, PTSD level mediated the relationships between those adaptational styles and embodiment intensity; that mediation was additionally moderated by a lack of knowledge about WWII trauma among ancestors in our participants. Our study adds to the literature on intergenerational trauma by highlighting the importance of evaluating embodiment in understanding the mechanisms of trauma transmission. Furthermore, it highlights the moderating effect of knowledge of family history in this mechanism and the need to share family histories with subsequent generations.
