- Objectives: The current study aimed to examine the mechanisms of change that mediate the impact of a compassionate mind training (CMT) intervention, in particular, whether changes in compassion, fears of compassion and heart rate variability (HRV) would mediate the effects of a brief CMT intervention on psychological vulnerability factors, mental health indicators and positive affect. Methods: Using a longitudinal design, general population participants were randomly assigned to one of the two conditions: compassionate mind training (n = 56) and wait list control (n = 37). Participants in the CMT condition attended a psychoeducation session and practiced a set of core CMT exercises for 2 weeks. Self-report measures of compassion, fears of compassion, self-criticism, shame, depression, stress and positive affect were completed, and HRV was assessed at pre- and post-intervention. Results: Mediation analyses revealed that increases in compassion for self and from others and reductions in fears of compassion for self, for others and from others mediated the effects of CMT on self-criticism and shame. In depression and stress, compassion for the self and from others and fears of compassion for the self emerged as significant mediators. Compassion for the self and from others and fears of compassion for self and from others significantly mediated the effect of CMT in safe affect. Compassion for the self, fears of compassion for self and for others and HRV mediated changes in relaxed affect. Conclusions: Cultivating a compassionate mind/self-identity through the core components of CMT may stimulate vagal regulatory activity and positively impact one’s ability to experience and be open to compassion, and thus promote emotion regulation, well-being and mental health.

Tidskriftsartikel (refereegranskat)abstract
- Here we aimed to unify some previous controversial reports on changes in both cannabinoid CB1 receptor (CB1R) expression and glucose metabolism in the forebrain of rodent models of diabetes. We determined how glucose metabolism and its modulation by CB1R ligands evolve in the frontal cortex of young adult male Wistar rats, in the first 8 weeks of streptozotocin-induced type-1 diabetes (T1D). We report that frontocortical CB1R protein density was biphasically altered in the first month of T1D, which was accompanied with a reduction of resting glucose uptake ex vivo in acute frontocortical slices that was normalized after eight weeks in T1D. This early reduction of glucose uptake in slices was also restored by ex vivo treatment with both the non-selective CB1R agonists, WIN55212−2 (500 nM) and the CB1R-selective agonist, ACEA (3 μM) while it was exacerbated by the CB1R-selective antagonist, O-2050 (500 nM). These results suggest a gain-of-function for the cerebrocortical CB1Rs in the control of glucose uptake in diabetes. Although insulin and IGF-1 receptor protein densities remained unaffected, phosphorylated GSKα and GSKβ levels showed different profiles 2 and 8 weeks after T1D induction in the frontal cortex. Altogether, the biphasic response in frontocortical CB1R density within a month after T1D induction resolves previous controversial reports on forebrain CB1R levels in T1D rodent models. Furthermore, this study also hints that cannabinoids may be useful to alleviate impaired glucoregulation in the diabetic cortex.

Tidskriftsartikel (refereegranskat)abstract
- ObjectivesCancer related pain (CRP) is among the most frequent collateral effects of cancer, with chronic CRP, lasting at least three months, affecting >40% of cancer survivors.Evidence based treatments, including pain-focused Cognitive Behavioral Therapy(CBT) are available, but it appears that cancer patients/survivors are often poorlyinformed about CRP or the potential benefits of CBT for such pain. The present studyexamines current experience of Swedish cancer patients/survivors in relation to CRP.MethodsParticipants (N= 276; 83% female; mean age = 55.5 years, SD=11.9) were recruited to an online survey via cancer websites in Sweden, and provided information about their history of chronic CRP, and whether they received information about or treatment for CRP from a healthcare professional.ResultsParticipants had a history of breast (36%), gynecological (12%), lung (10%), colon(8%) and other forms of cancer (36%). A majority (74%) reported a history of chronicCRP and being prescribed analgesic medications (70%). Less than half (47%)received information from their healthcare provider about the risk of CRP and only 13% with chronic CRP received psychological treatment, and of these only 33% received CBT. Among those receiving psychological treatment for chronic CRP, satisfaction rates were moderate, reported as an average of 6 on a 0-10 scale (SD 2.6).ConclusionsGreater efforts are needed to raise awareness among cancer patients/survivors, andhealthcare providers about the risk of CRP and evidence-based interventions,including CBT, the first-line intervention for chronic pain. These efforts will need to be matched with increases in treatment capacity, particularly pain-focused CBT.

Efficacy of an ACT and Compassion-Based eHealth Program for Self-Management of Chronic Pain (iACTwithPain) : Study Protocol for a Randomized Controlled Trial
- 2021
-
Ingår i: Frontiers in Psychology. - : Frontiers Media S.A.. - 1664-1078. ; 12
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Chronic pain (CP) has serious medical and social consequences and leads to economic burden that threatens the sustainability of healthcare services. Thus, optimized management of pain tools to support CP patients in adjusting to their condition and improving their quality of life is timely. Although acceptance and commitment therapy (ACT) is considered an evidence-based psychological approach for CP, evidence for the efficacy of online-delivered ACT for CP is still scarce. At the same time, studies suggest that self-compassion mediates the change in disability and psychopathological symptoms in ACT interventions for CP, although self-compassion is not a specific target in ACT. Thus, an explicit focus on self-compassion might increase the efficacy of ACT interventions for CP, although this hypothesis has not been tested. This study aims to develop an eHealth ACT and compassion-based self-management intervention for CP, the iACTwithPain, and to compare its efficacy in improving health outcomes to a similar ACT-only intervention and a medical TAU group.Methods: The eHealth platform that will host the interventions will be developed using a flat design identity and will be interactive. The iACTwithPain intervention will comprise eight weekly self-management sessions and will be developed taking into consideration the psychological flexibility model applied to CP, with the addition of explicit compassion-based components. To analyze whether the iACTwithPain intervention will present superiority in improving CP's impact and related health markers over the two other conditions, this study will follow an RCT design with three arms. CP patients will be recruited through direct contact with patient associations and healthcare services and a national press release in Portugal. Outcome measurement will be conducted at baseline, post-intervention and at 3- and 6-month follow-ups. The interventions' acceptability will also be assessed.Discussion: The iACTwithPain intervention is expected to improve CP patients' psychosocial functioning, quality of life, and empowerment, by promoting adaptive disease management and regulation of pain-related internal experiences. Results will contribute to a better understanding on the pertinence of adding compassion elements to ACT for CP and to reach an optimized intervention for CP.

Not All Emotional Demands Are the Same : Emotional Demands from Clients' or Co-Workers' Relations Have Different Associations with Well-Being in Service Workers.

- There has been an increased interest in the study of emotional demands (ED) at work and its impact on workers' well-being. However, ED have been conceptualized as a unitary concept, focused on interactions with clients, and excluding other potential sources of ED at work. Therefore, the aim of the current study is to explore the relation between ED from different relational sources (clients/patients/customers and colleagues, supervisors, and employees) and service workers' exhaustion and engagement. Cross-sectional data from a sample of 2742 service workers were analysed using structural equation modelling. Results showed that ED from both sources (clients and colleagues) were associated with more emotional exhaustion, particularly if dealing with clients was not an integrated part of the role. Further, ED from clients' relations were negatively associated with engagement for managers with staff responsibility, but positively for managers without staff responsibility. We also found moderating effects of psychosocial safety climate (PSC), whereby ED had the strongest effect on emotional exhaustion when PSC was low. This study suggests that different relational sources of ED at work have a different impact on employees' well-being. Strategies that promote a reduction of extra-role ED, and the development of a PSC in the organization, could therefore offer possible solutions to promote employees' psychological well-being and motivation.

Tidskriftsartikel (refereegranskat)abstract
- Background: Studies of individuals with non-cancer-related chronic pain, find that higher levels of psychological flexibility (PF) are associated with less distress, better functioning, and a better response to treatment. People diagnosed with cancer are at significantly increased risk of developing chronic cancer-related pain, the presence of which is associated with poorer health outcomes. Little is known about whether PF is applicable to cancer pain. The current study investigates the relationship between chronic cancer-related pain, distress and functioning, and three theoretical processes proposed by the PF model: pain acceptance, present-moment focus, and committed action. Methods: Adults (n = 246) with a cancer diagnosis (current or previous), and living in Sweden, completed an online survey involving standardized measures of cancer relatedpain (intensity and impairment), depression, fatigue, PF and social stigma. Results: Moderate to strong correlations were found between PF and all variables. In regression analyses, PF, and particularly pain acceptance, accounted for a large and significant proportion of the observed variance in depression, pain-related and overall functioning, after controlling for cancer status, pain intensity and social stigma.Conclusion: Consistent with studies of non-cancer-related pain, higher levels of PF were strongly associated with lower levels of distress and better functioning in individuals with cancer-related pain. Further studies are needed to further explore these relationships and to determine whether psychosocial treatments targeting PF may be of benefit to people with chronic cancer-related pain.

Usability Study of the iACTwithPain Platform : An Online Acceptance and Commitment Therapy and Compassion-Based Intervention for Chronic Pain
- 2022
-
Ingår i: Frontiers in Psychology. - : Frontiers Media S.A.. - 1664-1078. ; 13
-
Tidskriftsartikel (refereegranskat)abstract
- Background: This pilot study aims to test the usability of the iACTwithPain platform, an online ACT-based intervention for people with chronic pain, to obtain information on which intervention and usability aspects need improvement and on expected retention rates.Methods: Seventy-three Portuguese women with chronic pain were invited to complete the first three sessions of the iACTwithPain intervention assess their quality, usefulness and the platform's usability. Twenty-one accepted the invitation. Additionally, eight healthcare professionals working with chronic medical conditions assessed the platform and the intervention from a practitioner's point of view.Results: This study presented a considerable attrition rate (71.43%) among chronic pain participants, with six completers. There were no significant differences in demographic or clinical variables between dropouts and completers except for completed education (participants who dropped out presented less education than completers). Reasons for dropout were related to difficult personal events occurring during the time of the intervention, lack of time, or having forgotten. There seemed to be an overall satisfaction with both the intervention, its contents and form of presentation of information, and the platform, concerning its design, appearance, and usability. Real image videos were preferred over animations or audio by chronic pain participants. Healthcare professionals emphasized the appealing and dynamic aspects of the animation format.Conclusion: This study informs the ongoing improvement of the iACTwithPain platform and provides valuable information on aspects researchers should consider while developing online psychological interventions for chronic pain. Further implications are discussed.

Tidskriftsartikel (refereegranskat)abstract
- Plant traits-the morphological, anatomical, physiological, biochemical and phenological characteristics of plants-determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodiversity conservation, ecosystem and landscape management, restoration, biogeography and earth system modelling. Since its foundation in 2007, the TRY database of plant traits has grown continuously. It now provides unprecedented data coverage under an open access data policy and is the main plant trait database used by the research community worldwide. Increasingly, the TRY database also supports new frontiers of trait-based plant research, including the identification of data gaps and the subsequent mobilization or measurement of new data. To support this development, in this article we evaluate the extent of the trait data compiled in TRY and analyse emerging patterns of data coverage and representativeness. Best species coverage is achieved for categorical traits-almost complete coverage for 'plant growth form'. However, most traits relevant for ecology and vegetation modelling are characterized by continuous intraspecific variation and trait-environmental relationships. These traits have to be measured on individual plants in their respective environment. Despite unprecedented data coverage, we observe a humbling lack of completeness and representativeness of these continuous traits in many aspects. We, therefore, conclude that reducing data gaps and biases in the TRY database remains a key challenge and requires a coordinated approach to data mobilization and trait measurements. This can only be achieved in collaboration with other initiatives.

Konferensbidrag (refereegranskat)abstract
- Health applications have increasingly been used to improve physical, mental and social well-being. Chronic pain (CP) is defined as pain that lasts for a period of three months and causes sporadic or constant discomfort. In Portugal, the treatments for this type of pain are almost exclusively pharmacological and with known limited effects. Endowing patients with self-management skills, will help them cope with pain in a more effective way. Psychological treatments (e.g. mindfulness-based interventions) may play a relevant role here, because they intervene on a cognitive, emotional and behavioural level, which in turn helps the chronic pain patient to deal with pain-related disorders and suffering. The current availability of connected and powerful smartphones and tablets creates an opportunity to propose alternative pain management solutions that may be used immediately when pain appears, which has been the argument that favoured the pharmacological solutions. For this we propose a mobile application that guides patients on the mindfulness practice and to self-manage the sensed pain. Learning to gradually adequate pain management may have several advantages such as: reduced the number of consultation visits and consequent waiting lists; increased cost-effectiveness; self-management of chronic pain at the patient’s pace and according to their needs; extend access to the treatment to patients that reside in low density regions. Being an alternative to traditional treatment, the proposed treatment will be under the guidance of qualified health professionals that will supervise treatment sessions and perform the required assessments. By promoting patients’ self-management, the control and monitoring of the chronic pain condition is expected to improve greatly, which in turn may prevent the aggravation of the clinical condition. This research and the mobile application are being developed in a collaboration between the Centre for Research in Neuropsychology and Cognitive Behavioral Intervention of the University of Coimbra and the Institute of Systems and Robotics.

Forskningsöversikt (refereegranskat)abstract
- Acceptance and Commitment Therapy (ACT) has been widely tested for chronic pain, with demonstrated efficacy. Nevertheless, although there is meta-analytical evidence on the efficacy of face-to-face ACT, no reviews have been performed on online ACT in this population. The aim of this meta-analysis is to determine the efficacy of online ACT for adults with chronic pain, when compared with controls. PubMed, PsycINFO, CENTRAL, and Web of Knowledge were searched for randomized controlled trials (RCTs) of online-delivered ACT for chronic pain. Effects were analyzed at post-treatment and follow-up, by calculating standardized mean differences. Online-delivered ACT was generally favored over controls (5 RCTs, N = 746). At post-treatment, medium effects for pain interference and pain acceptance, and small effects for depression, mindfulness, and psychological flexibility were found. A medium effect for pain interference and acceptance, and small effects for pain intensity, depression, anxiety, mindfulness, and psychological flexibility were found at followup. ACT-related effects for pain interference, pain intensity, mindfulness, and anxiety increased from post-treatment to follow-up. Nevertheless, the current findings also highlight the need for more methodologically robust RCTs. Future trials should compare online ACT with active treatments, and use measurement methods with low bias.Perspective: This is the first meta-analytical review on the efficacy of online ACT for people with chronic pain. It comprises 5 RCTs that compared online ACT with active and/or inactive controls. Online ACT was more efficacious than controls regarding pain interference, pain intensity, depression, anxiety, mindfulness, and psychological flexibility.
