Accumbal serotonin hypofunction and dopamine hyperfunction due to chronic stress and palatable food intake in rats

ABSTRACT Feeding is regulated by energy homeostatic and pleasure-induced rewarding signals. Palatable food intake modifies serotonergic (5-HT) and dopaminergic (DA) pathways in nucleus accumbens, inducing neuronal maladaptations that favor hyperphagia for high-energy dense food and consequent obesity. Chronic stress is an environmental condition that increases the preference for palatable food by modulating brain DA and 5-HT metabolism. Objective: To evaluate the association between changes in accumbal 5-HT and DA metabolism and the effects of chronic stress, palatable food intake and their interaction with satiety/hunger condition. Methods: Wistar rats were housed in pairs (non-stressed) or individually (stressed), fed with chow or chocolate milk plus chow (Ch) for 2 weeks (4 groups); then 6 animals/group were 48 h fasted or maintained ad libitum; the rest were fasted and re-fed for 2 h either with chow or Ch. Results: Rats with prolonged high-energy density food intake and re-fed with chow showed reduced 5-HT metabolism, although there was no association with animals’ feeding behavior. In contrast, after re-fed with palatable food, stressed chow-fed rats had increased 5-HT turnover, which decreased in Ch re-fed rats, supporting that palatable food might induce positive mood changes related to high extracellular 5-HT in limbic regions. Discussion: Rats with prolonged palatable food intake exhibited high accumbal DA turnover independently of stress exposure, supporting its relation with the development of high-energy dense food hyperphagia. As accumbal 5-HT and DA metabolism changed due to fasting or re-feeding, alterations could represent the interaction of energy homeostatic and hedonic feeding signaling in animals.

Volitionally Regulated Breathing with Prolonged Expiration Influences Food Craving and Impulsivity

Introduction: Previously, an intervention involving volitional slow breathing reduced trait food craving with protective effects on cardiac vagal activity (CVA). Breathing with a low inspiration-to-expiration (i/e) ratio also increases CVA. High CVA was separately associated with low unregulated eating and lesser impulsivity. Hence, the present study assessed breathing with a low i/e for effects on state food craving, hunger and satiety, state impulsivity, and heart rate variability (HRV) in healthy obese persons. Methods: Forty obese persons were randomized to two groups. The intervention group (mean age ± SD, 41.15 ± 12.63, M:F, 10:10) practiced metronome-regulated breathing with low i/e at 12 breaths per minute (expiration 72% of total breath duration) and attained expiration 55.8% of total breath duration, while the active control group (mean age ± SD, 44.45 ± 11.06, M:F, 13:07) sat motionless and directed their gaze and awareness to the stationary metronome without modifying their breath consciously. The HRV was recorded before, during, and after breathing intervention (or control) (standard limb lead I, acquisition at 2,000 Hz, with an LF filter = 0.5 Hz and HF filter = 50 Hz). Time-domain and frequency-domain HRV parameters were obtained with Kubios software. State food craving, and hunger and satiety were recorded before and after the intervention/control. Results: The intervention group decreased total state food craving scores and the sub-domains (i.e., desire to eat, positive reinforcement, lack of control and hunger), increased current satisfaction with food, decreased total state impulsivity (repeated measures ANOVA, p < 0.05 in all cases), increased HF-HRV and RMSSD (linear mixed model analyses with age and gender as fixed factors; p < 0.05 in all cases) during the intervention compared to the preceding baseline. The intervention group also showed an increase in positive mood and a decrease in aroused and negative mood states. Conclusion: Changes in state food craving and impulsivity could be related to an increase in HRV or to changes in subjective relaxation and positive mood or to both.

Sonic Gathering Place: implementation of a biophilic soundscape design and its evaluation

The Sonic Gathering Place (SGP) is a prototype urban furniture installation that uses sound design to enhance the biophilic effects of plants. It uses field recordings from four different biomes in South-Eastern Australia mixed with plants that are representative of those biomes. The SGP has a circular seating structure comprising four integrated planter boxes, each with a single speaker. Nature-based field recordings play through the four-speaker array to create an immersive audio playback experience, though without masking the existing acoustic environment of the installation site. This paper focuses, as practice-led research, on the design process of the installation that encompasses four disciplinary approaches: soundscape design, biophilic design, field recording and urban furniture. Innovatively, it then reports a quantitative survey of the user’s experience of the SGP that hones understanding of human response to the design. Measured user-responses to the SGP, collected through a smartphone-based questionnaire, were overwhelmingly affirmative of the design, including a positive change in self-reported mood resulting from the visit to the SGP. These responses were observed with introduced sound levels set only marginally louder than sound levels that existed before the installation. The results signal a wider role that biophilic sound installations might play in urban landscape design.

Dance consumption and mood changes: Examining the role of gender and generational cohorts

PurposeThis paper aims to analyze the relationship between watching dance and mood enhancement considering potential differences across gender and age brackets.Design/methodology/approachExploratory research was undertaken through a personal survey, using a structured questionnaire on a large sample of young participants between 18 and 35 years old, split into generational cohorts (Millennials or Generation Y and Centennials or Generation Z). Quota sampling (gender and age) was the method used to select respondents.FindingsResults show that after watching dance, more positive mood changes were observed in general. However, they were stronger among women and younger Millennials. These findings are important as they open a new area of study; show the effects of culture on people; and help design programming strategies to enlarge audiences.Originality/valueThe effects of specific forms of arts and cultural participation on people’s moods have been analyzed from a diversity of disciplines. In the case of dance, studies have tested this relation among practitioners (active participants) but not among viewers (attendees) as this paper does.

An Initial Feasibility Trial of Providing Yoga in School for Children with Additional Support Needs.

Yoga is used widely as a therapeutic tool for physical and mental well-being. However, greater understanding of the effect yoga may have on young people who require additional support for learning is warranted. Therefore, the aim of the present study was to assess the feasibility of delivering and evaluating an 8-week school-based yoga program targeted to children with additional support needs in a mainstream primary school. Data were collected from 11 pupils (aged 4-12) with additional support needs. The Behavior Rating Inventory of Executive Function and Strengths and Difficulties Questionnaire were completed pre- and postintervention by parents and the pupil's schoolteachers. Observation of the yoga class engagement was conducted at baseline, midway through, and at the end of the intervention. A visual adaptation of the Children's Feeling Scale was completed each week pre- and post-yoga class by each student. Qualitative measures, including a parent feedback questionnaire, interview with the yoga instructor, and focus group with the pupil support assistants, were undertaken. The program was delivered as planned. The yoga instructor, parents, and pupil support assistants found the program to be beneficial to the students and a feasible part of their school week. There were no significant differences pre- to postintervention in any scores of the Strengths and Difficulties Questionnaire or Behavior Rating Inventory of Executive Function. Some positive changes in mood were found, although effect sizes were small. This study demonstrates the feasibility of delivering a school-based yoga program for children with additional support needs, as well as a feasible evaluation approach. The overall experiences for pupils, pupil support assistants, and the yoga teacher were positive and suggest that wider implementation and evaluation of the school-based yoga program would be of value.

Project Soothe: A pilot study evaluating the mood effects of soothing images collected using a citizen science approach

Background Mentally-generated soothing imagery is a therapeutic technique to support mental wellbeing, but some individuals may require support using externally presented stimuli. Project Soothe was launched to collect soothing images using a citizen science approach. This online pilot study evaluated the first 575 soothing images collected, examining: 1) if the images were perceived to be soothing; 2) if viewing the images had a positive impact on mood; and 3) if mood effects were influenced by individual differences in age, gender and depressive symptoms. Methods We recruited 1152 participants (13 – 79 years, M = 35.62, SD = 14.60; 77% female). Participants were randomly allocated to one of 23 sets, each containing 25 images (n = 50 per set) and asked to rate their emotional response (soothed, excited, and anxious) to each image. Participants also reported their mood states pre- and post-viewing the images (using the International Positive and Negative Affect Schedule – Short Form). Results Project Soothe images were rated to be significantly more soothing than anxiety- or excitement-inducing. Further, viewing 25 images was significantly associated with an increase in positive affect and decrease in negative affect. These effects were associated with age and depressive symptoms, with older individuals and those with lower depressive symptoms being associated with more positive changes in mood. Conclusions This pilot study provides preliminary evidence that these soothing images can promote positive mood changes. Further work can now replicate these findings in larger-scale studies with comparison groups and extended outcome variables. The images and associated data have been made available in a data repository (OSF) as a free resource for researchers and practitioners. It is hoped that these images can be developed into useful therapeutic resources.

Enhancing Hotel Guests’ Psychological Experience through Artistic Expression and Positive Mood Changes

We aimed to probe the effectiveness of art therapy on hotel guests’ self-awareness of mood. We introduced an art expression program at a hotel and examined its effect on self-awareness of mood changes among hotel guests. We let 47 hotel guests perform collage work and compared their self-awareness of mood before and after the art performance. The results showed a positive change in self-awareness of tension, confusion, fatigue, and vigor. A further elaboration of the art expression programs at hotels may add merits of staying in hotels. This study also demonstrated the possibility of cognitive psychology to apply to the hospitality business.

Greater usage and positive mood change for users of a dynamic VR app before and after the COVID-19 pandemic onset.

Americans reported an increase in stress during the novel coronavirus disease 2019 (COVID-19). Virtual reality (VR) apps have been shown to distract users from stressors in the environment, but little is known about the efficacy of specific content features to reduce stress or improve mood for consumer users during a pandemic. The present study investigated secondary archival data to explore how mood and usage behavior changed before and after the onset of COVID-19 for consumer users of a VR app with dynamic, interactive content. Study findings indicate that the COVID-19 pandemic had significant effects on user behavior and mood. Users created more accounts and used app content more often during the pandemic, while reporting increased negative mood states. This suggests that users were motivated to use the content to cope with pandemic stressors. Users also experienced a greater positive mood change after using the content during the pandemic than before, which implies that elements related to the VR app content met users' psychological needs. Passive content with less interactivity resulted in a greater positive mood state after the COVID-19 onset, likely related to its capacity to reduce stress, facilitate restoration, and improve persistent affective states in stressful environments. This study offers a vital window into how consumer users respond to psychosocial pandemic stressors outside of a controlled environment as well as the prospective for VR app content to serve as a valuable mental health intervention during similar stressful events.

Evaluating the Implementation of the Individualized Positive Psychosocial Interaction (IPPI) as a Quality Improvement Project in Nursing Homes

ABSTRACT Objectives The Individualized Positive Psychosocial Interaction (IPPI) is a non-pharmacological, person-centered, intervention for nursing home (NH) residents living with moderate to severe dementia. The purpose of this study was to assess the pragmatic implementation of the IPPI by leveraging Ohio’s Nursing Home Quality Improvement Program (QIP). Methods Implementation teams collected resident mood ratings pre- and post-IPPI and completed virtual interviews to assess their Organizational Readiness for Implementing Change as well as the acceptability, feasibility, and appropriateness of the IPPI. Implementation strategies included: providing ongoing consultation; identifying and preparing champions; assessing for readiness and identifying barriers; and developing and distributing effective educational materials. Results Fifteen NHs completed the QIP (65% completion rate) and reported high organizational commitment to change and high change efficacy. NHs engaged n = 65 residents in n = 638 IPPIs. Residents experienced a positive mood change after 47% of IPPIs. NHs found the IPPI program to be highly acceptable, feasible, and appropriate. Conclusions Overall, 65% of NHs successfully implemented the IPPI QIP with people living with moderate to severe dementia. Clinical Implications Given the positive mood changes and high staff satisfaction, results suggest that these brief, individualized activities can be effective strategies to address the communication of distress among PLWD.

Acute and Extended Anxiolytic Effects of Cannabidiol in Cannabis Flower: A Quasi-Experimental ad libitum Use Study.

Objective: Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD) have varying pharmacological actions with differential effects on acute and extended affective states, incuding anxiety. We aimed to study these effects on anxiety in legal market forms of cannabis. Method: This study makes use of a nonequivalent control group quasiexperimental design. Forty-two participants with anxiety symptions who were not using cannabis were compared to 258 participants with anxiety symptoms who used cannabis flower (∼3-4 times per week). Participants who used cannabis were randomly assigned to one of three legal market cannabis conditions; THC-dominant (24% THC, <1% CBD), THC+CBD (12% THC, 12% CBD), or CBD-dominant (<1% THC, 24% CBD). Changes in anxiety symptoms over 4-weeks were measured by the Patient Global Impression of Change (PGIC) scale and the Depression, Anxiety, and Stress Scale (DASS). Acute changes in subjective mood immediately after cannabis use were measured by the Profile of Mood States (POMS) Elation, Tension, and Paranoia subscales and the Addiction Research Center Inventory intoxication scale. Results: While all participants reported anxiety reductions over the 4-week study on the PGIC (F=30.65, p<0.001) and DASS anxiety measures (F=115.88, p<0.001), ad libitum CBD-dominant cannabis use was associated with lower scores on the DASS anxiety subscale compared to THC-dominant use when accounting for frequency of use (difference=-1.03, SE=0.45, p=0.02). Similarly, acute CBD-dominant cannabis use was associated with lower scores on the POMS tension and paranoia subscales (POMS tension: CBD-dominant vs. THC-dominant: difference=-0.41 SE=0.1, p<0.001; CBD-dominant vs. THC+CBD: difference=-0.28, SE=0.07, p=0.04; POMS paranoia: CBD-dominant vs. THC-dominant: difference=-0.49, SE=0.1, p<0.001; CBD-dominant vs. THC+CBD: difference=-0.33, SE=0.09, p=0.01). Participants in all cannabis conditions experienced acute changes in positive mood and subjective drug effects. Conclusions: This study provides novel information on the impacts of legal market cannabis with varying ratios of THC to CBD in indviduals with anxiety symptoms. Findings suggest that THC did not increase anxiety and that CBD-dominant forms of cannabis were associated with acute tension reduction that may translate to longer-term reductions in anxiety symptoms. Clinical Trial Registration: NCT03491384.

The shape of the change: Cumulative and incremental changes in daily mood during mobile-app-supported mindfulness training.

Understanding of the exact trajectories of mood improvements during mindfulness practice helps to optimize mindfulness-based interventions. The Mindfulness-to-Meaning model expects mood improvements to be linear, incremental, and cumulative. Our findings align with this expectation. We used multilevel growth curve models to analyze daily changes in positive mood reported by 190 Polish participants during 42 days of a mobile-app-supported, mindfulness-based intervention. The daily positive mood increased among 83.68% of participants. Participants who started the training reported worse mood improved more and faster than participants with better mood at the baseline. Dispositional mindfulness and narcissism - individual difference variables associated with high vs. low emotion regulation ability, respectively - were not associated with mood improvement trajectories. A small group of participants (16.32%) showed a steady decline in positive mood during the intervention. The results underscore the importance of a more comprehensive understanding of individual variability in benefiting from mindfulness-based interventions.

Acceptability of ACT group intervention for adolescents with type 1 diabetes

BackgroundType 1 diabetes (T1D) is a demanding condition for both adolescents and their parents. The first aim of this study was to investigate the acceptability of an acceptance and commitment therapy (ACT) group intervention for 12–16-year-old adolescents with T1D. The second aim was to investigate how adolescents whose glycemic control improved during the intervention differed from those who did not improve. MethodsA total of 28 adolescents and their parents who completed the intervention were interviewed at the end of the intervention. The adolescents filled in questionnaires regarding diabetes-related psychological flexibility (DAAS) and acceptance and mindfulness (CAMM) before and after the intervention. Glycosylated hemoglobin (HbA1c) levels were obtained from the medical records before and after the intervention. The experiences of the intervention were investigated using semi-structured questionnaires and a thematic analysis. Statistical analyses were performed to study the group differences between adolescents who improved in glycemic control and those who showed no improvement. ResultsOf those who completed the intervention, 86% of the adolescents and 89% of the parents reported being very satisfied or satisfied with the intervention. The thematic analysis showed that among the themes arising from the experiences of adolescents were increased motivation for the treatment of diabetes and a better attitude toward diabetes. Among the parents, themes such as positive changes in mood, a better attitude toward diabetes, and increased motivation for treatment emerged. In terms of group differences, those who improved with regard to glycemic control were older, their HbA1c was higher at the start, and they reported greater changes in diabetes-related psychological flexibility. ConclusionsThe ACT-based group intervention was well accepted and complemented the usual treatment. Thus, this intervention is recommended, especially for adolescents who have not met the glycemic targets.

Capturing mood dynamics through adolescent smartphone social communication.

Most adolescents with depression remain undiagnosed and untreated-missed opportunities that are costly from both personal and public health perspectives. A promising approach to detecting adolescent depression in real-time and at a large scale is through their social communication on the smartphone (e.g., text messages, social media posts). Past research has shown that language from online social communication reliably indicates interindividual differences in depression. To move toward detecting the emergence of depression symptoms intraindividually, the present study tested whether sentiment (i.e., words connoting positive and negative affect) from smartphone social communication prospectively predicted daily mood fluctuations in 83 adolescents (Mage = 16.49, 73.5% female) with a wide range of depression severity. Participants completed daily mood ratings across a 90-day period, during which 354,278 messages were passively collected from social communication apps. Greater positive sentiment (i.e., more positive weighted composite valence score and a greater proportion of words expressing positive sentiment) predicted more positive next-day mood, controlling for previous-day mood. Moreover, greater proportions of positive and negative sentiment were, respectively, associated with lower anhedonia and greater dysphoria symptoms measured at baseline. Exploratory analyses of nonaffective linguistic features showed that greater use of social engagement words (e.g., friends and affiliation) and emojis (primarily consisting of hearts) predicted more positive changes in mood. Collectively, findings suggest that language from smartphone social communication can detect mood fluctuations in adolescents, laying the foundation for language-based tools to identify periods of heightened depression risk.

Image Recommendation System Based on Environmental and Human Face Information.

With the advancement of computer hardware and communication technologies, deep learning technology has made significant progress, enabling the development of systems that can accurately estimate human emotions. Factors such as facial expressions, gender, age, and the environment influence human emotions, making it crucial to understand and capture these intricate factors. Our system aims to recommend personalized images by accurately estimating human emotions, age, and gender in real time. The primary objective of our system is to enhance user experiences by recommending images that align with their current emotional state and characteristics. To achieve this, our system collects environmental information, including weather conditions and user-specific environment data through APIs and smartphone sensors. Additionally, we employ deep learning algorithms for real-time classification of eight types of facial expressions, age, and gender. By combining this facial information with the environmental data, we categorize the user's current situation into positive, neutral, and negative stages. Based on this categorization, our system recommends natural landscape images that are colorized using Generative Adversarial Networks (GANs). These recommendations are personalized to match the user's current emotional state and preferences, providing a more engaging and tailored experience. Through rigorous testing and user evaluations, we assessed the effectiveness and user-friendliness of our system. Users expressed satisfaction with the system's ability to generate appropriate images based on the surrounding environment, emotional state, and demographic factors such as age and gender. The visual output of our system significantly impacted users' emotional responses, resulting in a positive mood change for most users. Moreover, the system's scalability was positively received, with users acknowledging its potential benefits when installed outdoors and expressing a willingness to continue using it. Compared to other recommender systems, our integration of age, gender, and weather information provides personalized recommendations, contextual relevance, increased engagement, and a deeper understanding of user preferences, thereby enhancing the overall user experience. The system's ability to comprehend and capture intricate factors that influence human emotions holds promise in various domains, including human-computer interaction, psychology, and social sciences.

The images and associated data have been made available in a data repository (OSF) as a free resource for researchers and practitioners. It is hoped that these images can be developed into useful therapeutic resources.

The Effect Of Dysmenorrhea On Mood Changes In 2020 Yarsi University Faculty Of Medicine Students And According To Islamic Perspective

Background: Dysmenorrhea is defined as painful uterine cramps occurring during menstruation and is one of the most common causes of abdominal pain and menstrual disorders. Not all women who experience menstruation feel comfortable; this is caused by general disturbances such as mood swings, joint pain, and abdominal pain, which is called dysmenorrhea. Women with dysmenorrhea need knowledge about the effects of dysmenorrhea on mood changes. The effect of dysmenorrhea on mood in 2020 YARSI University Faculty of Medicine student is unknown.Methods: This type of research is descriptive-analytic with a cross-sectional study approach. The sample in the study consisted of students from the Faculty of Medicine at YARSI University, class of 2020, with 120 respondents. Data was collected by filling out a questionnaire to measure pain and mood changes, namely Numeric Rating Scale (NRS) and Four Dimensions Mood Scale (FDMS). The analysis was carried out univariately on each variable and bivariate to see the relationship between variables. Results: The results showed that YARSI University Faculty of Medicine students who experienced mild, moderate, and severe dysmenorrhea with negative mood changes, respectively, were 5 people (10.4%), 5 people (10.6%), and 14 people (56%). Mild, moderate, and severe dysmenorrhea with relaxation mood swings affected 10 people (20.8%), 31 people (66%), and 6 people (24%). Mild, moderate, and severe dysmenorrhea with positive mood changes, respectively, affected 33 people (68.8%), 1 person (23.4%), and 5 people (20%). The results of the Chi-Square analysis showed a relationship between the incidence of dysmenorrhea and mood swings.Conclusion: There is a relationship between the incidence of dysmenorrhea and mood swings in 2020 YARSI University Faculty of Medicine students.

Sea swimming as a novel intervention for depression and anxiety - A feasibility study exploring engagement and acceptability

BackgroundOutdoor swimming is increasingly popular, with enthusiasts claiming benefits to mental health. However, there is limited research into its effectiveness as an intervention for people with depression and/or anxiety. We aimed to establish recruitment rates and explore potential benefits, for a sea swimming course offered to people with depression and/or anxiety. MethodsThis was a singlearm, unblinded feasibility study. 61 participants, were recruited to an eight-session sea-swimming course. Attendance rates were recorded. Self-administered questionnaires were completed at baseline, post-course and at three-month follow-up. Free-text descriptions of thoughts about the course were collected using surveys, and 14 participants kept a diary. Results53 participants (47 female, 5 male, 1 non-binary) were included in the final analysis. Overall attendance was 90.1%. There were reductions showing large effect (between d = 1.4 to 1.7) in the severity scores of both depression and anxiety between the beginning and end of the course. While severity scores marginally increased at three-month follow-up, a reduction from baseline scores for depression, anxiety (d = 1.2 and 1.4, respectively) and functioning scores (d = 0.8) remained. The qualitative analysis identified that ‘confronting challenges', ‘becoming a community’ and ‘appreciating the moment’ were key to the impact, or the 'mechanisms', that resulted in participants experiencing the 'outcomes' of ‘immediate positive changes in mood’, ‘improved mental and physical health’ and ‘increased motivation to swim’. ConclusionsThis study provides preliminary support for the engagement and acceptability of sea swimming as a novel intervention for depression and/or anxiety. Participants reported positive changes in mental health, indicating the intervention's potential as a public health resource. There was a clear gender difference, which requires further exploration. Larger scale trials are warranted.

Feasibility of Pilates for Late-Stage Frail Older Adults to Minimize Falls and Enhance Cognitive Functions

Globally, we are facing the tendency of aging, and demands for health enhancement among the older population have been steadily increasing. Among various exercise interventions, Pilates has been popularly utilized in rehabilitation; therefore, it is considered suitable for vulnerable populations. In this study, frail late-stage older adults (&gt;75 years) participated in a modified Pilates program (30 min per session, once a week for eight weeks). Age- and condition-matched Controls were also involved as the benchmark to reveal the effect of Pilates. While only the Pilates group participated in the exercise intervention, both groups undertook the health assessments twice (before and after the intervention period). Assessments included: (i) falling risk based on 3D motion capture systems and (ii) overall cognitive functions utilizing Mini-Mental State Examination and executive function with the use of Trail Making Test-A (TMT-A). Two-dimensional mood state was also used to measure changes in mood due to Pilates intervention. An 8-week Pilates intervention was effective in achieving higher and symmetrical swing foot control. Dynamic balance at heel contact was also improved by extending the spatial margin in case of slipping. Despite the trend of positive Pilates effects on executive functions (29% improvement) confirmed by TMT-A, no significant effects were observed for cognitive functions. Positive mood changes were achieved by Pilates intervention, which may be the key for late-stage seniors to continue their participation in exercise programs. While further studies with a larger sample size are essential, Pilates appears to provide adequate exercise for the frail late-stage older population to minimize frailty.

Prospective examination of the therapeutic role of psychological flexibility and cognitive reappraisal in the ceremonial use of ayahuasca.

Evidence suggests that psychedelic-assisted therapy carries transdiagnostic efficacy in the treatment of mental health conditions characterized by low mood and the use of avoidance coping strategies. While preliminary evidence suggests that psychological flexibility and emotion regulation processes play an important role within psychedelic therapy, this prospective study addressed methodological gaps in the literature and examined the ability of ayahuasca to stimulate acute states of cognitive reappraisal and long-term changes in psychological flexibility and mood. The study also explored whether moderating factors predisposed participants to experience therapeutic changes. Participants (N = 261) were recruited from three Shipibo ayahuasca retreat centers in Central and South America and completed assessments on mood, psychological flexibility, and acute ceremonial factors. Expectancy, demand characteristics, and invalid responding were controlled for with several validity scales. Participants reported significant reductions in negative mood after three months, as well as increases in positive mood and psychological flexibility. Acute experiences of reappraisal during the ayahuasca ceremony exerted the strongest moderating effects on increases in positive mood and psychological flexibility. Increases in psychological flexibility statistically mediated the effects of acute psychological factors, including reappraisal, on changes in positive mood. These results highlight the role of acute psychological processes, such as reappraisal, and post-acute increases in psychological flexibility as putative mechanisms underlying positive outcomes associated with psychedelics. These results also provide support for the integration of third-wave and mindfulness-based therapy approaches with psychedelic-assisted interventions.

The Role of Individual Characteristics in Predicting Short- and Long-Term Cognitive and Psychological Benefits of Cognitive Stimulation Therapy for Mild-to-Moderate Dementia

Introduction: This study examined the role of individual characteristics in predicting short- and long-term benefits of the Italian version of Cognitive Stimulation Therapy (CST-IT), an evidence-based intervention for people with mild-to-moderate dementia.Materials and Methods: Data were drawn from a sample (N = 123) of people with dementia (PwD) who took part in a multicenter controlled clinical trial of CST-IT. Assessments at pre-test, immediately after completing the treatment, and 3 months later investigated the following outcomes: general cognitive functioning and language, mood and behavior, everyday functioning, and quality of life. Age, education and baseline (pre-test) cognitive functioning, mood (depression) and behavioral and neuropsychiatric symptoms were considered as predictors of any short- and long-term benefits.Results: Linear mixed-effects models showed that different individual characteristics -particularly education and age- influenced the benefits of CST-IT, depending on the outcome measures considered. Higher education predicted larger gains in general cognitive functioning and, along with less severe depressive symptoms, in language (magnification effects). Older age was associated with positive changes in mood (compensation effects). Albeit very modestly, older age was also associated with larger gains in everyday functioning (compensation effects). Gains in quality of life were predicted by older age and lower education (compensation effects). Baseline cognitive functioning, mood and/or behavioral symptoms broadly influenced performance too, but their role again depended on the outcomes considered.Discussion: These findings underscore the importance of considering and further exploring how psychosocial interventions like CST are affected by individual characteristics in order to maximize their efficacy for PwD.
