Companion animals are often assumed to benefit human emotional wellbeing, yet empirical evidence for this effect and the proposed stress-buffering mechanism underlying this effect is heterogeneous. This study examined whether momentary interaction with a companion animal is associated with pet owners’ positive and negative affect in daily life, and whether these interactions buffer the affective impact of stress. We further tested whether these associations differ between interacting with dogs versus cats. Using ecological momentary assessment (EMA), 188 dog and cat owners reported their affect, stress, and interactions with their companion animals at random moments up to 10 times per day over five consecutive days. Multilevel regression analyses accounting for repeated measurements nested within individuals, including random intercepts and slopes, and controlling for age, gender, and social context, showed that pet interaction was associated with higher positive and lower negative affect, independent of species. No evidence for a stress-buffering effect was found, instead a species-specific pattern emerged for negative affect in response to event-related stress: interactions with cats amplified, rather than attenuated, the association between stress and negative affect. Overall, findings support robust momentary emotional benefits of interacting with companion animals, but do not support stress-buffering as the mechanism underlying this association. These results emphasize the importance of considering both species and situational context when examining the psychological impact of human–animal interaction.

Human-animal interactions (HAI) may relate to animal caregivers’ affect, also referred to as the “pet effect”. However, studies have not explored these associations in work contexts or evaluated longitudinal patterns of HAI with other activities across work and non-work contexts, and their associations with caregiver emotions. We therefore assess momentary associations between HAI during (tele)work and non-work time and positive and negative caregiver affect (PA/NA), identify person-level patterns of longitudinal HAI state trajectories, and analyze cross-level moderating effects of these patterns on momentary associations between HAI and PA/NA. First, we evaluated associations between momentary HAI and caregiver PA/NA including the moderating role of momentary work state (teleworking vs. not working). Second, using a data-driven approach, we applied sequence analysis to determine heterogeneity in state trajectories amongst caregivers using working activity and animal presence in five possible states (working at work/teleworking with animal/teleworking without animal/not working with animal/not working without animal), which we labelled as animal-work constellations. Similar trajectories of animal-work constellations across caregivers were grouped into clusters with recognizable patterns. Third, we assessed whether such patterns moderated momentary associations between HAI and caregiver PA/NA. Caregivers (N_persons = 324) completed ecological momentary survey data during five days with 10 prompts per day (N_observations = 16,127) between 2017 and 2024. Results showed that momentary associations between HAI and affect were moderated by momentary work state and person-level animal-work constellation pattern, contextualizing the “pet effect”. Our results highlight the importance of microlevel investigations of animal-work constellations and validates the novel use of sequence analysis to explore the role of context and time.

Previous studies in adult samples have shown that emotions, especially positive emotions, are one of the key mechanisms of change in positive psychology interventions. The current research aimed to investigate whether these emotions also mediate the effect of a positive psychology intervention, based on mindfulness and strengths use for adolescents, on mental health outcomes (i.e., well-being, peer-related and attentional problems). A quasi-experimental study was performed, including assessments one week before and one week after the intervention. The results of the multilevel mediation analyses showed that adolescents who completed the intervention (N=70) experienced a significant decrease in negative emotions but no significant increase in positive emotions compared to adolescents who did not participate in the intervention (N=236). Changes in negative emotions mediated changes in mental health outcomes (i.e., well-being and peer-related problems) associated with the intervention. Further, adolescents who started, but not necessarily completed the intervention (N=116) experienced no significant decrease in negative emotions. Findings suggest that positive psychology interventions may have an effect on health outcomes by decreasing negative emotions in addition to fostering positive emotions.

The contribution of companion animals to human mental wellbeing has received an increasing amount of scientific interest. Research findings concerning the nature of this relationship are however mixed. Variability in behavior and characteristics of the animal might explain this heterogeneity. The main aim of the present study is to investigate the association between companion animals and mental wellbeing in daily life and the role that animal characteristics play in this association, using an ecological momentary assessment approach. The sample will comprise of adult owners of a dog and/or a cat. Participants will start with a baseline assessment including demographic characteristics of the owner and the animal, as well as the C‐BARQ or Fe‐BARQ to assess general behavior of the animal. After the baseline assessment, a signal‐contingent scheme with semi‐random intervals will be used to examine human–animal interaction (HAI) in the natural setting of pet‐owners' daily lives. Participants will complete up to ten short assessments per day over the course of 5 days, reporting on the presence of‐, interaction with‐, and behavior of the companion animal. They also report on stressful activities and events, and on their current positive and negative affect. Multilevel regression analysis will be used to investigate the relationship between HAI, animal characteristics and mental wellbeing. With this study we hope to provide insight into the type of animal, behavior of the animal and specific elements of interaction with an animal, and their potential associations with human wellbeing. The knowledge gathered in this study will add to unraveling mechanisms underlying HAI and help to identify in which contexts and under what conditions HAI can have the greatest impact.

Previous studies conducted during the COVID-19 pandemic found an increased risk of lonelinessdue to measurements taken by governments to limit social interaction. The current study addressesthe relationship between loneliness and both positive and negative mental health in timesof the COVID-19 pandemic and the role of psychological flexibility.Data was collected in the Dutch general population (18+) with two online questionnaires (T1-T2), with an interval of four weeks. A sample of 340 participants varying in age from 18 to 83years (Mage (SD): 52.83 (13) and 61.8 % female), filled in both questionnaires. Loneliness and (thesix core processes of) psychological flexibility were measured at T1 and negative mental health(depression, anxiety and stress) and positive mental health (emotional, psychological and socialwell-being) at T2.Regression analyses indicated a positive (prospective) relation between loneliness anddepression, anxiety and stress and a negative (prospective) relation between loneliness andemotional, psychological and social well-being. Psychological flexibility had a moderating effecton the relation between loneliness and depression but not on the relation between loneliness andrespectively anxiety, stress or well-being. Looking at the six core processes of psychologicalflexibility, being present and committed action were significant moderators of the relation betweenloneliness and depression.We conclude that while it has yet to be determined whether the moderating relationships foundin this study hold beyond COVID-19 conditions, the findings do provide support for the benefits ofpsychological flexibility to intervene in situations where external circumstances or psychologicalchallenges are beyond one’s control.

Previous research emphasizes the importance of well-being in old age and its association with positive mental and physical health at earlier stages of aging during midlife. Acceptance and Commitment Therapy has the potential to support positive aging processes. This study examines the feasibility and acceptability of a new unguided eHealth ACT module in a population from 40 years onwards. Data were collected at two measurement points in time (before and after completion of the ACT module). In total, 313 participants (range = 40–75 years; mean(SD) = 54 years (8.3); 76% female) had 8 weeks access to the ACT module and responded to the feasibility questionnaire, upon completion of the module. Logged data (time spent online per session and in total, number of attended sessions) was also analyzed. Of the respondents, 76% reported a completion rate of 75%–100%. On average, 3.5 h (SD = 6.4) per week were spent on the module and practicing the ACT skills. The mean evaluation of the module was 7.4 (SD = 1.2, range = 1–10). Approximately 80% of the participants rated each session as (very) good. Absence of guidance was marked as a limitation. The results indicate good feasibility and acceptance of this unguided eHealth module. This is a promising result as this is, to our knowledge, the first study applying an eHealth ACT module to the general population in the context of positive aging. The effectiveness results will be addressed in a future paper.

This study investigated the efficacy of a school-based intervention (8 sessions of 45 min) based on mindfulness and character strengths use (i.e., “Think Happy-Be Happy”). A quasi-experimental study, including assessments at baseline, post-intervention (i.e., one week after the intervention), and follow-up (i.e., six months after the intervention) was performed. Results at post-intervention revealed that adolescents who participated in all intervention sessions experienced significantly increased well-being (i.e., emotional, psychological, and social well-being) and decreased hyperactivity/inattention symptoms and peer-related problems compared to adolescents who did not participate in the intervention. The “intention to treat” analyses showed that adolescents who started the intervention, regardless of the number of sessions they attended, experienced significantly decreased hyperactivity/inattention symptoms compared to adolescents who did not participate in the intervention. However, significant outcomes were not maintained at follow-up. Nevertheless, this study demonstrates that integrating mindfulness with strengths use in school-based interventions might have the potential to promote the mental health of adolescents in terms of both increased well-being and reduced psychological problems.

Background: The coach-coachee working alliance and coachee motivation seem important factors for achieving positive coaching results. Self-determination theory, specifically basic psychological need theory, has been proposed as a relevant framework for understanding these relationships. The current longitudinal survey study therefore investigates prospective associations between coachees’ appraisal of the working alliance, basic psychological need satisfaction, and the coaching outcome indicators goal attainment, wellbeing, absence of psychopathology, and personal growth initiative.Methods: The sample (N = 181) consisted of Dutch coachees that were recruited across a range of coaching settings and contexts. Online self-report questionnaires were administered twice (T₀and T₁), with an intervening time of 3 weeks, assessing working alliance, basic psychological need satisfaction, goal attainment, wellbeing, absence of psychopathology, and personal growth initiative. Parallel analysis with Monte Carlo simulations and confirmatory factor analyses were performed to assess the dimensionality of working alliance and basic psychological need satisfaction scores. Multiple regression analyses (stepwise) were used to examine prospective (T₀to T₁) associations between working alliance and basic psychological need satisfaction, and their association with outcome indicators.Results: The coachees’ perception of the working alliance was positively and reciprocally, although modestly, associated with basic psychological need satisfaction. In addition, both working alliance and basic psychological need satisfaction were prospectively associated with goal attainment, but not with other outcome indicators.Conclusions: Results provide tentative support for a role of basic psychological need satisfaction in facilitating the establishment of a good working alliance. Additionally, the perception of a good quality, need supportive relationship with the coach appears to be associated with better goal achievement, but not with other outcome indicators. Associations were generally modest, and more research is needed to better measure and comprehend the unique contributions of specific relational and motivational factors to outcomes in coaching and assess the robustness of the current study findings.
