Beyond emotions: Social cognitive predictors of Covid-19 vaccination intentions before and after vaccine roll-out
Understanding the drivers of COVID-19 vaccination intentions remains relevant as public health systems prepare for future pandemics. This study examined how emotional and social-cognitive factors influence COVID-19 vaccination intentions during two key phases of the COVID-19 pandemic: before (April-June 2020) and after (January-February 2021) vaccination rollout. A total of 586 adults completed an online survey assessing beliefs about COVID-19, s…
Beyond the average: Idionomic evidence of individual-specific variability in the psychological flexibility-mood relationship
Past research has relied on normative analyses for establishing the positive relationship between psychological flexibility (PF) process and well-being. These analyses, however, assume that aggregate-level effects (i.e., this positive relationship) also apply to most individuals, limiting our ability to explore the dynamic and complex nature of PF processes that interact with individual factors. Idionomic analyses, which use idiographic effects a…
Through thick and thin: How friendship and psychological flexibility shape our response to being ostracized
Introduction: Social connections are vital to human wellbeing, yet interactions often entail misunderstandings and disappointments. When ostracized, people react with strong emotional pain. In this experiment, we investigated whether principles derived from psychotherapy and/or the presence of a friend could mitigate negative reflexive and reflective reactions to ostracism induced using the Cyberball experiment. We tested how participants respond…
Studying Daily Social Interaction Quantity and Quality in Relation to Depression Change: A Multi-Phase Experience Sampling Study
Day-to-day social life and mental health are intertwined. Yet, no study to date has assessed how the quantity and quality of social interactions in daily life are associated with changes in depressive symptoms. This study examines these links using multiple-timescale data (iSHAIB data set; N = 133), where the level of depressive symptoms was measured before and after three 21-day periods of event-contingent experience sampling of individuals’ int…
Psychological flexibility, parental competence, and prosociality in caregivers of children with special health care needs: A network analysis of family functioning and child outcomes
Distinct pathways to well-being: Exploring valued action and mood among stoics and non-stoics
To examine the relationship between valued action and mood, this study analyzed Ecological Momentary Assessment data from a transdiagnostic in- and out-patient sample (EMA; N = 134; 62 female, 72 male; 62 inpatient, 72 outpatient; M age = 36.6 years, SD = 11.6). Individual time series models were constructed to capture each participant's unique relationship between valued action and mood. The models were then meta-analyzed, revealing substantial …
Contextual similarities in psychological flexibility: The Brazil-Portugal transcultural adaptation of Psy-Flex
Psychological Flexibility is an essential concept in Contextual Behavioural Sciences. The development of instruments is vital for its study, and it is an opportunity to reflect on this concept. Among the measures of this construct, Psy-Flex shows promise due to comprehensiveness in assessing the six facets of psychological flexibility and its pragmatic value. In the present study, we sought to translate Psy-Flex to Portuguese and adapt it transcu…
The compassion connection: Experience sampling insights into romantic attraction
Our study examines the relationship between self-compassion, other-compassion, and romantic attraction in couples, and questions the psychological homogeneity assumption—the idea that psychological responses are uniform across individuals and couples. We analyzed data from 161 participants in 84 couples, with an average age 32 (SD = 12.02), using smartphones for event sampling six times daily over a week to measure self-compassion, other-compassi…
Coping with emotional pain: An experimental comparison of acceptance vs. avoidance coping
Increasing psychological flexibility is associated with positive therapy outcomes following a transdiagnostic ACT treatment
This study adds further evidence for psychological flexibility as a transdiagnostic process variable of successful psychotherapy. Limitations are discussed
Predictors of changing patterns of adherence to containment measures during the early stage of Covid-19 pandemic: An international longitudinal study
BACKGROUND: Identifying common factors that affect public adherence to COVID-19 containment measures can directly inform the development of official public health communication strategies. The present international longitudinal study aimed to examine whether prosociality, together with other theoretically derived motivating factors (self-efficacy, perceived susceptibility and severity of COVID-19, perceived social support) predict the change in a…
Predictors of Embarrassment in Daily Social Interactions in Social Phobia, Major Depression and Healthy Controls
Introduction: Embarrassment is a social affect. Once experienced in social interactions (SIs), it can be a precursor of clinical symptoms like depersonalization and ruminative thinking. This experience sampling study investigated predictors of embarrassment in social phobia (SP), major depressive disorder (MDD), and controls. Methods: For seven days, a total of n = 165 patients (n = 47 SP, n = 118 MDD) and n = 119 controls completed five surveys …

Is giving receiving? The influence of autonomy on the association between prosocial behavior and well-being
Prosocial behavior represents an evolutionary advantage for individuals. In line with this claim, several studies showed a positive relation between prosocial behavior and well-being. However, negative relations were also reported in the literature. This study aimed to assess the relation between prosocial behavior and well-being using an event sampling methodology. Further, we were interested in two contextual factors (closeness of the receiver …
Can psychological flexibility and prosociality mitigate illness perceptions toward Covid-19 on mental health? A cross-sectional study among Hong Kong adults
BACKGROUND: The negative impact of COVID-19 pandemic on public mental health can be persistent and substantial over a long period of time, but little is known regarding what psychological factors or processes can buffer such impact. The present study aimed to examine the mediating roles of coping, psychological flexibility and prosociality in the impacts of perceived illness threats toward COVID-19 on mental health. METHOD: Five-hundred and fourt…
Psy-Flex: A contextually sensitive measure of psychological flexibility
Psychological flexibility is increasingly studied in various contexts including clinical studies. The construct has been hypothesized to be a major determinant of mental health. Existing measures lack context-sensitivity (e.g, implicitly measuring it as a trait) and/or reference to a limited time frame. We developed a short self-report measure that covers all facets of the construct and is context-sensitive. Data was collected from four separate …
I won't comply because it is a hoax: Conspiracy beliefs, lockdown compliance, and the importance of psychological flexibility
Report of the ACBS Task Force on the strategies and tactics of contextual behavioral science research
Throughout its history the strategy and tactics of contextual behavioral science (CBS) research have had distinctive features as compared to traditional behavioral science approaches. Continued progress in CBS research can be facilitated by greater clarity about how its strategy and tactics can be brought to bear on current challenges. The present white paper is the result of a 2 1/2-year long process designed to foster consensus among representa…
Patterns of Psychological Responses among the Public during the Early Phase of Covid-19: A Cross-Regional Analysis
This study aimed to compare the mediation of psychological flexibility, prosociality and coping in the impacts of illness perceptions toward COVID-19 on mental health among seven regions. Convenience sampled online survey was conducted between April and June 2020 from 9130 citizens in 21 countries. Illness perceptions toward COVID-19, psychological flexibility, prosociality, coping and mental health, socio-demographics, lockdown-related variables…
Your phone ruins our lunch: Attitudes, norms, and valuing the interaction predict phone use and phubbing in dyadic social interactions
Phubbing—ignoring another person in order to use a smartphone instead—is an increasingly common behavior that disrupts interactions and harms relationships. Using the frameworks of the theory of planned behavior and an interaction value approach, we examined the driving factors of phubbing frequency. Four preregistered predictors were tested: attitudes toward phubbing, subjective norms of phubbing, interaction value, that is, the extent of valuin…
Impact of Covid-19 pandemic on mental health: An international study
Background The COVID-19 pandemic triggered vast governmental lockdowns. The impact of these lockdowns on mental health is inadequately understood. On the one hand such drastic changes in daily routines could be detrimental to mental health. On the other hand, it might not be experienced negatively, especially because the entire population was affected. Methods The aim of this study was to determine mental health outcomes during pandemic induced l…
