Item Adapting to Adversity: Effects of COVID-19 on Parenting in Chile(2022) Perez Ewert, J. Carola; Aldoney, Daniela; Vivanco-Carlevari, Anastassia; Coo, Soledad; Guzmán, Eugenio J.; Silva, Jaime R.The pandemic outbreak in March 2020 and its associated sanitary regulations and restrictions triggered an abrupt and significant change for society in general and for families’ organization in particular. In Chile, the Santiago Metropolitan District was under a strict lockdown that involved the closure of the entire educational system. From a systemic-family stress perspective, the impact of these changes might have consequences not only for each individual family member, but for the parental dynamic and, consequently, for children’s well-being. This paper presents the results of a followup study showing changes in self-reported parental depression and the perceived home organization of mothers and fathers assessed at three different moments: before the pandemic, at the initial outbreak, and after 1 month of strict lockdown. Relevant moderators were explored using linear mixed models to understand the within-subject changes in mothers’ and fathers’ self-reports across the different assessment times. Financial strain, personality traits of self-criticism and dependency, previous parent– child quality interaction, recent major stressful events, and number of children are highlighted as relevant factors that moderate changes in home chaos and parental mental health perception. Significant risks and protective factors are described for fathers and mothers. The use of pre-pandemic measures as baseline levels enabled the identification of personal and family characteristics that were related to better outcomes. The results help increase our understanding of the sanitary regulations’ impacts on the family system and identify vulnerability indicators that should be considered.Item Biological stress reactivity as an index of the two polarities of the experience model(2017) Silva, Jaime R.; Vivanco-Carlevari, Anastassia; Barrientos, Mauricio; Martínez, Claudio; Salazar, Luis A.; Krause, MarianeThe two-polarities model of personality argues that experience is organized around two axes: interpersonal relatedness and self-definition. Differential emphasis on one of these poles defines adaptive and pathological experiences, generating anaclitic or introjective tendencies. The anaclitic pattern, on one hand, has been conceptually related with an exaggerated emphasis on interpersonal relatedness. On the other hand, the introjective pattern has been connected to high levels of self-criticism. The aim of this study was to investigate the psychophysiological basis for this relationship. Specifically, we hypothesized that the anaclitic individual should have a higher biological reactivity to stress (BRS), measured by the cortisol concentration in saliva, in an interpersonal stress induction protocol (Trier Social Stress Test). Contrary to what was expected, the results indicated that introjective participants presented a higher BSR than the anaclitic group. Interestingly, in contrast to their higher BSR, the introjective group reported a diminished subjective stress in relation to the average. In the anaclitic group, a tendency that goes in the opposite direction was found. Theoretical implications of these findings were discussed.Item Hydrocortisone decreases metacognitive efciency independent of perceived stress(2020) Reyes, Gabriel; Vivanco-Carlevari, Anastassia; Medina, Franco; Manosalva, Carolina; Gardelle, Vincent de; Silva, Jaime R.; Sackur, JérômeIt is well established that acute stress produces negative effects on high level cognitive functions. However, these effects could be due to the physiological components of the stress response (among which cortisol secretion is prominent), to its psychological concomitants (the thoughts generated by the stressor) or to any combination of those. Our study shows for the first time that the typical cortisol response to stress is sufficient to impair metacognition, that is the ability to monitor one’s own performance in a task. In a pharmacological protocol, we administered either 20 mg hydrocortisone or placebo to 46 male participants, and measured their subjective perception of stress, their performance in a perceptual task, and their metacognitive ability. We found that hydrocortisone selectively impaired metacognitive ability, without affecting task performance or creating a subjective state of stress. In other words, the single physiological response of stress produces a net effect on metacognition. These results inform our basic understanding of the physiological bases of metacognition. They are also relevant for applied or clinical research about situations involving stress, anxiety, depression, or simply cortisol use.Item Introjective Individuals Tend Toward Anhedonia: Self-Report and Experimental Evidence(2018) Silva, Jaime R.; Vivanco-Carlevari, Anastassia; Martínez, Claudio; Krause, MarianeA broad line of research has conceptualized personality based on the interaction of two aspects: interpersonal relatedness and self-definition. This theoretical corpus understands these functions as two poles according to the patterns of interaction and relevance in personality. Additionally, the exacerbation of one of these poles generates a psychopathological model that identifies three types of depressive experience: anaclitic, introjective, or mixed pattern. Understanding the lack of interest as a key symptom of depression, this experiment evaluates a relation for anhedonia and the polarities model configuration using an empirical and experimental protocol. We tested 177 individuals using the Beck Depression Inventory (BDI) subscale for anhedonia and a visual discrimination task with a specific reward system, which was implemented to study reinforcement sensitivity. Participants were classified into four groups by the polarities of experience model. The subscale’s results showed that individuals with an introjective character exhibited an enhanced anhedonic symptomatology but no co-occurrence of this evidence on the experimental protocol. These results empirically support the two polarities of the depressive personality model and raise new questions regarding how to experimentally test this relation.Item Social Support and Depressive Symptoms in the Context of COVID-19 Lockdown: The Moderating Role of Attachment Styles(2022) Costa-Cordella, Stefanella; Vivanco-Carlevari, Anastassia; Rossi, Alejandra; Arévalo-Romero, Camilo; Silva, Jaime R.Objectives: COVID-19 sanitary measures (social distancing, school closures) have deeply impacted social life, support networks, and their protective role in mental health. The present study aims to understand how attachment styles influence the way individuals experience social support. Particularly, investigating its moderating role in the relationship between social support and depression. Methods: An online survey was designed to clarify the role of adult attachment styles (ECR-S) in the perceived social support (MOSS) and self-reported depressive symptoms (BDI-SF) in the COVID-19 context. Results: Positive social interactions was the most important dimension of social support for lower depression symptoms. Individuals attachment strategies have a moderating role in the relation between of social support and depression. Crucially, insecure attachment style wanes the positive impact of social support in depression. Conclusion: Aligned with the existing literature, attachment security is an essential factor in our current understanding of relationships and mental health. Exploring specific and indivual attachment strategies might be a powerful tool to protect population’s mental health.
