Validation of the Montreal Pain and Affective Face Clips (MPAFC): The role of sex and participants’ pain status / Validación del set Montreal Pain and Affective Face Clips (MPAFC): rol del sexo y estado de dolor de los participantes

Background: The use of pain-related stimuli in experimental psychology studies has increased in the last few years. Consequently, various sets of stimuli have been created for this purpose. Aims: To analyze the validity of the pain faces of Montreal Pain and Affective Face Clips (MPAFC), in Spanish participants with and without pain. Method: A total of 291 participants completed psychological self-report and pain measures and were asked to rate the prototypicality and emotional intensity of the eight pain-related faces from the MPAFC by rating. The sample was divided into three groups depending on the participants’ pain status (chronic, acute, or pain-free). Results: Three of the eight pain faces did not reach a higher rating than 5 (on a 0-10 points scale) in both dimensions. Regarding the pain status, there were no significant differences in the ratings between groups of participants. Female faces were rated as significantly more prototypical and emotionally intense than male faces. Limitations:As we used the last image of every clip, this study is based just on static images of the pain facial expression, which may be less representative of the emotion. Conclusion: Overall, the presence of pain in participants did not significantly affect their assessment of the faces. Female faces were significantly rated as more prototypical and more emotionally intense than male faces. From our results, we conclude that experimental studies about pain should explore and report the validity of the selected stimuli to optimize the adequacy of the stimuli. (AU)

Antecedentes: El uso de estímulos relacionados con el dolor en los estudios de psicología experimental ha aumentado en los últimos años. En consecuencia, se ha creado una variedad de conjuntos de estímulos para este fin. Objetivos: Analizar la validez de las caras de dolor del Montreal Pain and Affective Face Clips (MPAFC), en participantes españoles con y sin dolor. Método: Un total de 291 participantes completaron medidas psicológicas de autoinforme y de dolor y valoraron la prototipicidad y la intensidad emocional de las ocho caras de dolor del MPAFC. La muestra se dividió en tres grupos en función del dolor de los participantes (crónico, agudo o sin dolor). Resultados: Tres de las ocho caras de dolor no alcanzaron una valoración superior a 5 (en una escala de 0-10 puntos) en ambas dimensiones. En cuanto al estado de dolor, no hubo diferencias significativas en las puntuaciones entre los grupos. Los rostros femeninos se calificaron como significativamente más prototípicos y emocionalmente más intensos que los masculinos. Limitaciones:Este estudio se basa sólo en imágenes estáticas de la expresión facial del dolor, que pueden ser menos representativas de la emoción. Conclusiones: En general, la presencia de dolor en los participantes no afectó significativamente a su valoración de los rostros. Los rostros femeninos fueron valorados significativamente como más prototípicos y más intensos emocionalmente que los masculinos. Como conclusión, los estudios experimentales sobre dolor deberían explorar e informar sobre la validez de los estímulos seleccionados para optimizar la adecuación de los estímulos. (AU)

Unlocking the past: efficacy of guided self-compassion and benefit-focused online interventions for managing negative personal memories.

Positive reappraisal strategies have been found to reduce negative affect following the recall of negative personal events. This study examined the restorative effect of two mood-repair instructions (self-compassion vs benefit-focused reappraisal) and a control condition with no instructions following a negative Mood Induction Procedure by using the guided recall of a negative autobiographical event. A total of 112 university students participated in the online study (81% women, Mage: 21.0 years). Immediately following the negative memory recall, participants were randomised to each condition [(self-compassion: n = 36, benefit-focused: n = 39) or a control condition (n = 37)]. Repeated measures ANOVAs 3 (Repair condition) × 3 (Time of mood assessment: pre-recall, post-recall, post-regulation) showed that, as expected, negative mood (sadness, shame, and guilt) worsened significantly after the guided recall in all groups (p < .001). After the mood-repair intervention, participants in the self-compassion and benefit-focused conditions showed a significant reduction in negative mood (p < .019), while such improvement was not observed in the control group. Self-compassion and benefit-focused reappraisal functioned similarly as mood repair strategies after experiencing negative affect induced by the recall of negative personal memories. Implications in the context of autobiographical memory biases are discussed.

An integrative analysis of potential mechanisms of reduced positive affect in daily life in depression: an ESM study.

Decreased levels of positive affect (PA) are a hallmark of depression. Current models propose as potential main mechanisms a dysfunctional use of emotion regulation (ER) strategies (i.e. dampening, positive rumination), and a maladaptive activation of pro-hedonic goals. However, the role of these mechanisms in PA in daily life remains understudied. We used a 10-day ESM design to assess how these mechanisms influence each other and contribute to depressive symptomatology-related low momentary PA in 139 individuals. Higher depressive symptoms were associated with lower PA, pro-hedonic goals, more frequent use of positive rumination, and higher use of dampening. Further, experiencing higher levels of PA predicted lower following time point use of dampening in individuals with higher symptoms. Finally, using positive rumination was more beneficial (i.e. predicted higher PA increases one moment later) for individuals with higher symptomatology. Our findings suggest that moment-to-moment changes in PA daily life are affected by, and have an effect on, both pro-hedonic goals and the use of dampening and positive rumination, highlighting specific cognitive-affective mechanisms that should be considered when designing interventions aimed at improving low PA characterising depression symptomatology.

The network structure of psychopathological and resilient responses to the pandemic: A multicountry general population study of depression and anxiety.

Commonly identified patterns of psychological distress in response to adverse events are characterized by resilience (i.e., little to no distress), delayed (i.e., distress that increases over time), recovery (i.e., distress followed by a gradual decrease over time), and sustained (i.e., distress remaining stable over time). This study aimed to examine these response patterns during the COVID-19 pandemic. Anxiety and depressive symptom data collected across four European countries over the first year of the pandemic were analyzed (N = 3,594). Participants were first categorized into groups based on the four described patterns. Network connectivity and symptom clustering were then estimated for each group and compared. Two thirds (63.6%) of the sample displayed a resilience pattern. The sustained distress network (16.3%) showed higher connectivity than the recovery network (10.0%) group, p = .031; however, the resilient network showed higher connectivity than the delayed network (10.1%) group, p = .016. Regarding symptom clustering, more clusters emerged in the recovery network (i.e., three) than the sustained network (i.e., two). These results replicate findings that resilience was the most common mental health pattern over the first pandemic year. Moreover, they suggest that high network connectivity may be indicative of a stable mental health response over time, whereas fewer clusters may be indicative of a sustained distress pattern. Although exploratory, the network perspective provides a useful tool for examining the complexity of psychological responses to adverse events and, if replicated, could be useful in identifying indicators of protection against or vulnerability to future psychological distress.

Epigenetic, psychological, and EEG changes after a 1-week retreat based on mindfulness and compassion for stress reduction in healthy adults: Study protocol of a cross-over randomized controlled trial.

INTRODUCTION: The main objective of the study will be to evaluate the effects of two widely used standardized mindfulness-based programs [Mindfulness-Based Stress Reduction (MBSR) and Compassion Cultivation Training (CCT)], on epigenetic, neurobiological, psychological, and physiological variables. METHODS: The programs will be offered in an intensive retreat format in a general population sample of healthy volunteer adults. During a 7-day retreat, participants will receive MBSR and CCT in a crossover design where participants complete both programs in random order. After finishing their first 3-day training with one of the two programs, participants will be assigned to the second 3-day training with the second program. The effects of the MBSR and CCT programs, and their combination, will be measured by epigenetic changes (i.e., DNA methylation biomarkers), neurobiological and psychophysiological measures (i.e., EEG resting state, EKG, respiration patterns, and diurnal cortisol slopes), self-report questionnaires belonging to different psychological domains (i.e., mindfulness, compassion, well-being, distress, and general functioning), and stress tasks (i.e., an Arithmetic Stress Test and the retrieval of negative autobiographical memories). These measures will be collected from both groups on the mornings of day 1 (pre-program), day 4 (after finishing the first program and before beginning the second program), and day 7 (post-second program). We will conduct a 3-month and a 12-month follow-up using only the set of self-report measures. DISCUSSION: This study aims to shed light on the neurobiological and psychological mechanisms linked to meditation and compassion in the general population. The protocol was registered at clinicaltrials.gov (Identifier: NCT05516355; August 23, 2022).

How do mindfulness and compassion programs improve mental health and well-being? The role of attentional processing of emotional information.

BACKGROUND AND OBJECTIVES: Although the benefits of Meditation-Based Programs are well documented, the mechanisms underlying these benefits have not been fully elucidated. Therefore, we examined whether: (1) formal training in mindfulness and compassion meditation modifies the distribution of attentional resources towards emotional information; and (2) whether changes in attentional processing of emotional information after the meditation programs mediate the improvements in psychological distress, emotion regulation, and well-being. METHODS: A sample of 103 participants enrolled in the study: 36 in the mindfulness program (MBSR), 30 in the compassion program (CCT), and 37 in the no-intervention comparison group (CG). The assessment before and after the programs included the completion of an emotional Attentional Blink task (AB) together with self-report measures of psychological distress, emotion regulation, and well-being. RESULTS: MBSR and CCT reduced similarly the AB deficit, whereas no changes occurred in the CG. This AB reduction was found for the different emotional and non-emotional stimuli (i.e., negative, positive, and neutral), showing a significant disengagement from first-target emotions and significant accessibility of second-target emotions to consciousness. The effects of both meditation programs on the psychological measures were mediated by changes in the AB and emotion regulation skills. LIMITATIONS: Due to our naturalistic design in a real-world community setting, random assignment of participants was not feasible. CONCLUSIONS: Meditation may promote more flexible and balanced attention to emotional information, which may be a key transdiagnostic mechanism underlying its benefits on emotional distress and well-being.

Posttraumatic growth in people affected by an occupational accident: A longitudinal multilevel model of change.

This study analyzed a predictive model of posttraumatic growth (PTG) in a cohort of 244 workers affected by an occupational accident. A longitudinal design with three points in time (i.e., 1, 6, and 12 months after the accident) was used. PTG, posttraumatic stress symptoms (PTSS), subjective severity of the event, deliberate rumination, and seeking social support were evaluated. In addition, time since the accident, age, and gender were included as predictors in our model. Deliberate rumination and seeking social support significantly predicted PTG trajectory in a multilevel model. Practical conclusions from the results suggest that work accident victims should be encouraged to seek social support and to positively reframe their experience.

The effect of mindfulness on the inflammatory, psychological and biomechanical domains of adult patients with low back pain: A randomized controlled clinical trial.

OBJECTIVE: This study aims to study the effect of mindfulness-based program on the psychological, biomechanical and inflammatory domains of patients with chronic low back pain. METHODS: A multicentre randomized and controlled clinical trial of parallel groups in patients with chronic low back pain between March 2019 to March 2020. Participants with no experience in mindfulness based intervention, were randomized to receive (36 patients) or not (34 patients) mindfulness-based stress reduction program for chronic back pain (MBSR-CBP). The program was performed in 9 sessions. Patients with chronic low back pain due to symptomatic discopathy (degenerative disc disease or herniated disc) were included. The principal outcome was changes in the blood level of cortisol and cytokines (tumor necrosis factor- α (TNF- α), interleukin-1ß (IL-1ß), interleukin-6 (IL-6) and interleukin-17 (IL-17)). Secondary outcomes (psychological factors, pain, and quality of life) were measured by validated questionnaires. RESULTS: Of the 96 randomized patients, 70 who completed the study were included in the analysis (mean [range] age: 53 [33-73] years; 66% females). MBSR-CBP stopped the increase in cortisol, and reduced pro-inflammatory cytokine IL-1ß (p = 0.05). It reduced depression (p = 0.046) and stress (p = 0.0438), perceived pain (p < 0.0001), and limitations related to health (p < 0.0001). It also increased the physical function (p = 0.002) and sleep quality (p = 0.05). Furthermore, it significantly increased life satisfaction (0.006), well-being (p = 0.001) and vitality (p < 0.0001). It also increased self-compassion (p < 0.0001) and significantly reduced the overidentification (p<0.0001) and catastrophization (p = 0.002). CONCLUSIONS: MBSR-CBP could be part of a multidisciplinary approach in the management of patients suffering from chronic low back pain.

Efficacy of mindfulness to regulate induced emotions in the laboratory: A systematic review and meta-analysis of self-report and biobehavioral measures.

A substantial part of the research on the efficacy of mindfulness-based interventions on mood regulation is conducted in the laboratory. Nevertheless, a systematic review of the results is lacking. This meta-analysis aimed to investigate the effects of mindfulness as an emotion regulation (ER) strategy when using mood induction procedures. A systematic search of databases was conducted and a total of 43 studies were included in the meta-analysis. We found a small significant overall effect size of mindfulness [g= -0.15 (95% CI [-0.30, -0.01], p = 0.04)], which became non-significant after removing outliers (g=-0.15, p = 0.06). We also found high levels of heterogeneity which was not explained by the moderating variables analyzed. Thus, there is limited meta-analytic evidence of the efficacy of mindfulness strategies in down-regulating or preventing heightened or chronic effects of induced mood states in well-controlled laboratory settings. We propose that this could be partially due to some limitations in laboratory methodologies and suggest some guidelines to overcome them in future primary research.

The mediating role of controllability appraisals and coping strategies on adaptive functioning after job loss: a path model.

Job loss is a stressful event that increases the risk of experiencing depression and anxiety, especially during the initial months of unemployment. This study examined differences in psychological symptoms and resilient functioning accounted by employment status. The results pointed out that recently unemployed compared to currently employed individuals had lower levels of perceived controllability and resilience as well as higher levels of depression and anxiety. Path analyses showed that lower controllability appraisals at wave 1 of recently unemployed compared to employed individuals, in turn, predicted a lower use of active coping and reappraisal at wave 2, with the latter further accounting for lower levels in resilience. Higher use of distraction further mediated the relation between employment status and higher levels of depression and anxiety symptoms. Our findings demonstrate the importance of controllability appraisals and coping strategies used to promote adaptive psychological functioning following job loss.

Causal Attributions and Perceived Severity as Predictors of Posttraumatic Stress Symptoms after a First Myocardial Infarction / Atribuciones causales y gravedad percibida como predictores de síntomas de estrés post-traumático tras un primer infarto de miocardio

Recent meta-analyses have shown a significant link between symptoms of anxiety and depression, and cardiovascular diseases (CVDs). The presence of these symptoms has a direct impact on the course and the recovery from the CVDs. A less analyzed aspect is the role played by the stress induced by the onset of CVDs conditions and, especially, by acute myocardial infarction (AMI). In this study, we assessed posttraumatic stress symptoms (PTSS), emotional state, health habits, and subjective perception of the event and causal attributions regarding the infarct, in a sample of 76 patients who had suffered an AMI in the previous 48-72 hours. Structural equation analyses and path analyses showed that the severity of PTSS was predicted by the perceived severity of the AMI and by two specific beliefs (i.e., considering that the AMI is a hereditary condition and that the help of others will not be beneficial). The results suggest the possibility of early identification of patients with a higher risk of suffering a high level of stress derived from the AMI. Based on this evidence, we discuss the possibilities of making effective interventions to reduce these symptoms, often ignored in clinical practice, and improve the medical and psychological prognosis of people with AMI.(AU)

Metanálisis recientes han demostrado una asociación significativa entre los síntomas postraumáticos y las enfermedades cardiovasculares (ECV). La presencia de este tipo de síntomas psicopatológicos tiene un impacto directo en el curso y la recuperación de dichas enfermedades. Un aspecto menos estudiado es el papel que juega el estrés provocado por la vivencia de una enfermedad cardiovascular, y, en especial, por el infarto agudo de miocardio (IAM). En este estudio se evaluaron los síntomas postraumáticos, el estado emocional, los hábitos de salud, la percepción subjetiva del suceso y las atribuciones causales respecto al infarto, en una muestra de 76 pacientes que habían sufrido un IAM en las 48-72 horas previas. El análisis de ecuaciones estructurales y el análisis de sendero (path analysis) mostraron que tanto la gravedad percibida del IAM, como dos creencias concretas (considerar que el infarto es un problema hereditario y que la ayuda de otros no es beneficiosa), predecían la gravedad percibida de los síntomas postraumáticos. Los resultados sugieren la posibilidad de identificar precozmente a los pacientes con mayor riesgo de sufrir un alto nivel de estrés derivado del IAM, gracias a sus atribuciones y su percepción de la gravedad del infarto. En base a esta evidencia, se discuten las posibilidades de realizar intervenciones efectivas para reducir estos síntomas y mejorar el pronóstico de las personas que han sufrido un IAM.(AU)

Relations between emotion regulation strategies and affect in daily life: A systematic review and meta-analysis of studies using ecological momentary assessments.

Emotion regulation (ER) is a central target in the study of psychological and neurobiological processes of emotions for numerous psychological disorders. Ecological momentary assessments, overcoming retrospective self-reports, allow a better understanding of the relation between the use of ER strategies and daily life affective experiences. A systematic review and meta-analyses of studies testing these relations through experience sampling methods (ESM) and daily diaries were conducted. ESM studies showed significant large effect sizes in contemporaneous relations between negative affect (NA) and rumination, suppression, and worry, and in both contemporaneous and prospective relations between positive affect (PA) and reappraisal; medium effect sizes in prospective relations between NA and rumination, and PA and distraction; and a small effect size in the prospective relation between NA and suppression. Daily diary studies showed significant large effect sizes in contemporaneous relations between NA and rumination and suppression, and in both contemporaneous and prospective relations between PA and reappraisal; medium effect sizes in contemporaneous relations between PA and acceptance, and problem-solving; and a small effect size in the prospective relation between NA and reappraisal. These findings shed light on the temporal relations between the use of ER strategies and affective experiences and highlight conceptual and methodological limitations in the field.

The network structure of paranoia dimensions and its mental health correlates in the general population: The core role of loneliness.

Paranoid ideas are the most common abnormal beliefs in the schizophrenia spectrum, are also prevalent in non-clinical populations, and are highly correlated with other mental health problems such as anxiety, depression and low levels of well-being. Two previous studies with the same British population sample used confirmatory factor analysis and network analysis to show that the spectrum of paranoid beliefs is made up of four factors or dimensions (i.e., interpersonal sensitivity, mistrust, ideas of reference and ideas of persecution). The aims of this study are: 1) to explore the distribution and the structure of paranoid beliefs in a Spanish general population by applying the network approach and 2) to use network analysis to explore for the first time whether specific domains of paranoid ideation (i.e., dimensions) are specifically associated with mental health correlates such as depression, anxiety, loneliness, and well-being. We found a continuous distribution of paranoid beliefs among the 1328 individuals constituting the sample (e.g., 29,2 % did not endorse any items, 4.6 % endorsed half of the items, while 0.8 % endorsed all paranoid items). Paranoid ideas form three dimensions; interpersonal sensitivity, mistrust, and ideas of persecution (ideas of reference did not form a separate factor). The network model showed that loneliness has a pivotal role in connecting paranoid ideation with general psychopathology measures (i.e., depression, anxiety, loneliness and well-being). Research and clinical implications derived from our findings are also discussed.

Measurement invariance of the Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder scale (GAD-7) across four European countries during the COVID-19 pandemic.

BACKGROUND: The Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder scale (GAD-7) are self-report measures of major depressive disorder and generalised anxiety disorder. The primary aim of this study was to test for differential item functioning (DIF) on the PHQ-9 and GAD-7 items based on age, sex (males and females), and country. METHOD: Data from nationally representative surveys in UK, Ireland, Spain, and Italy (combined N = 6,054) were used to fit confirmatory factor analytic and multiple-indictor multiple-causes models. RESULTS: Spain and Italy had higher latent variable means than the UK and Ireland for both anxiety and depression, but there was no evidence for differential items functioning. CONCLUSIONS: The PHQ-9 and GAD-7 scores were found to be unidimensional, reliable, and largely free of DIF in data from four large nationally representative samples of the general population in the UK, Ireland, Italy and Spain.

Design, content, and fieldwork procedures of the COVID-19 Psychological Research Consortium (C19PRC) Study - Wave 4.

OBJECTIVES: This paper outlines fieldwork procedures for Wave 4 of the COVID-19 Psychological Research Consortium (C19PRC) Study in the UK during November-December 2020. METHODS: Respondents provided data on socio-political attitudes, beliefs, and behaviours, and mental health disorders (anxiety, depression, and posttraumatic stress). In Phase 1, adults (N = 2878) were reinvited to participate. At Phase 2, new recruitment: (i) replenished the longitudinal strand to account for attrition; and (ii) oversampled from the devolved UK nations to facilitate robust between-country analyses for core study outcomes. Weights were calculated using a survey raking algorithm to ensure the longitudinal panel was representative of the baseline sample characteristics. RESULTS: In Phase 1, 1796 adults were successfully recontacted and provided full interviews at Wave 4 (62.4% retention rate). In Phase 2, 292 new respondents were recruited to replenish the panel, as well as 1779 adults from Wales, Scotland, and Northern Ireland, who were representative of the socio-political composition of the adult populations in these nations. The raking procedure successfully re-balanced the longitudinal panel to within 1% of population estimates for selected socio-demographic characteristics. CONCLUSION: The C19PRC Study offers a unique opportunity to facilitate and stimulate interdisciplinary research addressing important public health questions relating to the COVID-19 pandemic.

Disentangling the mediating role of modifying interpretation bias on emotional distress using a novel cognitive bias modification program.

BACKGROUND: Negative interpretation bias is a potential risk factor for emotional disorders. In this study, we tested a clinically inspired 4-session online Cognitive Bias Modification-Interpretation (CBM-IClin) program to modify negative interpretation biases. METHODS: We randomized one hundred and twenty-one volunteer young adults (Mean age = 21.6 years, SD = 3.5; 85 % women) with varying levels of emotional distress to either an experimental or waitlist control group. Mediation analyses were used to disentangle the associations between the intervention, changes in interpretation biases (assessed by both a self-report and an experimental task), and changes in measures of cognitive vulnerability and symptoms of depression and anxiety. RESULTS: The results showed that the CBM-IClin could change negative interpretation biases. Also, it had a direct effect on the change in negative memory bias, an indirect effect on the change in depression symptoms via the change in interpretation bias, and both direct and indirect effects on the change in self-reported dysfunctional attitudes. LIMITATIONS: The study included a non-clinical sample of participants and it did not control for some potential confounding factors (e.g., attentional disorders). Furthermore, participants' engagement during the sessions at home was not supervised. CONCLUSIONS: The CBM-IClin is a potential tool to prevent and intervene in emotional disorders in young adults and could complement other traditional CBM procedures or clinical interventions.

'Relearning how to think': A brief online intervention to modify biased interpretations in emotional disorders-study protocol for a randomised controlled trial.

BACKGROUND: Cognitive biases play an important role in the development and maintenance of emotional disorders, such as depression and anxiety. Novel procedures, known as Cognitive Bias Modification (CBM), aim to reduce these dysfunctional information processing modes. This study develops a brief clinically based online intervention programme to modify biased interpretations in depression and anxiety (CBM-IClin), overcoming some methodological issues that have been addressed in previous literature. METHODS: Volunteer participants will be recruited via social media and posters at the university. They will be randomly assigned to an experimental group or a waiting list control group. Both groups will complete two assessment sessions (before and after the intervention) consisting of questionnaires measuring cognitive and emotional variables as well as experimental tasks measuring cognitive biases (i.e. attention, memory, and interpretation). After the first assessment session, only participants in the experimental group will receive a link to follow the four CBM-IClin sessions at home. All participants will receive, via email, follow-up questionnaires 2 weeks and 3 months after the second assessment. DISCUSSION: This study will test the 'Relearning how to think', an online programme potentially beneficial to modify cognitive biases in emotional disorders. Several limitations of previous CBM procedures are addressed, and the impact of the programme both on objective cognitive bias tasks and clinical symptoms will be explored. TRIAL REGISTRATION: ClinicalTrials.gov NCT03987477 . Prospectively registered on June 17, 2019.

Context, design and conduct of the longitudinal COVID-19 psychological research consortium study-wave 3.

OBJECTIVES: The COVID-19 Psychological Research Consortium (C19PRC) Study aims to assess the impact of the COVID-19 pandemic in the adult population in multiple countries. This paper describes the third wave of the UK survey (the 'parent' strand of the Consortium) during July-August 2020. METHODS: Adults (N = 2025) who participated in the baseline and/or first follow-up surveys were reinvited to participate in this survey, which assessed: (1) COVID-19 related knowledge, attitudes, and behaviours; (2) the occurrence of common mental disorders; as well as the role of (3) psychological factors and (4) social and political attitudes, in influencing the public's response to the pandemic. Weights were calculated using a survey raking algorithm to ensure that the cross-sectional sample is nationally representative in terms of gender, age, and household income, and representative of the baseline sample characteristics for household composition, ethnicity, urbanicity and born/raised in UK. RESULTS: 1166 adults (57.6% of baseline participants) provided full interviews at Wave 3. The raking procedure successfully re-balanced the cross-sectional sample to within 1% of population estimates across selected socio-demographic characteristics. CONCLUSION: This paper demonstrates the strength of the C19PRC Study data to facilitate and stimulate interdisciplinary research addressing important public health questions relating to the COVID-19 pandemic.

Cognitive Control, Cognitive Biases and Emotion Regulation in Depression: A New Proposal for an Integrative Interplay Model.

Research traditions on cognition and depression focus on relatively unconnected aspects of cognitive functioning. On one hand, the neuropsychological perspective has concentrated on cognitive control difficulties as a prominent feature of this condition. On the other hand, the clinical psychology perspective has focused on cognitive biases and repetitive negative patterns of thinking (i.e., rumination) for emotional information. A review of the literature from both fields reveals that difficulties are more evident for mood-congruent materials, suggesting that cognitive control difficulties interact with cognitive biases to hinder cognitive switching, working memory updating, and inhibition of irrelevant information. Connecting research from these two traditions, we propose a novel integrative cognitive model of depression in which the interplay between mood-congruent cognitive control difficulties, cognitive biases, and rumination may ultimately lead to ineffective emotion-regulation strategies to downregulate negative mood and upregulate positive mood.
