Satiety regulation in children with loss of control eating and attention-deficit/hyperactivity disorder: a test meal study

Children with loss of control (LOC) eating and attention-deficit/hyperactivity disorder (ADHD) are at risk for excessive weight gain. However, it is unclear whether or not these children show disturbances in hunger and satiety regulation. The goal was to examine the food intake and sense of LOC over eating as well as LOC eating-related characteristics during test meal in children with LOC eating and ADHD. Children aged 8-13 y with LOC eating (n = 33), ADHD (n = 32), and matched healthy controls (n = 33), consumed a test meal consisting of their chosen lunch food, with the instruction to eat until feeling full. Sense of LOC over eating, desire to eat, feelings of hunger, and liking of food were repeatedly assessed during test meal. Children with LOC eating and ADHD did not show a higher food intake at maximum satiety compared to control children. Sense of LOC over eating was significantly higher in children with LOC eating compared to children with ADHD and matched controls. Secondary analyses revealed that children with LOC eating ate marginally faster than control children. Both children with LOC eating and ADHD reported greater desire to eat, feelings of hunger, and liking of food during test meal than control children. Even though the results did not reveal statistical evidence to support the assumption of a disturbed food intake in children with LOC eating and ADHD, LOC eating related characteristics were significantly higher in these children compared to the control children. Sense of LOC over eating was confirmed as a specific characteristic of LOC eating. The examination of behavioral indicators of hunger and satiety dysregulation should be complemented with physiological indicators in future research

Daily Work Stress and Relationship Satisfaction: Detachment Affects Romantic Couples' Interactions Quality

Psychologically detaching from work in the private setting is crucial to recover from work stress and promotes well-being. Moreover, broad evidence documents negative effects of stress on relationship quality. However, the interpersonal consequences of detachment have barely been studied. We seek to investigate, in daily life, whether and how detachment affects the interaction quality with the romantic partner. We propose that stress impedes detaching from work, and that detachment in turn, promotes individuals’ ability to engage in positive interactions at home, which increases individual and relational well-being. In a first experience sampling study, involving 106 dual-earner couples with young children, detachment mediated the association between work stress and not only the stressed individual’s, but also their partner’s relationship quality. However, positive (affectionate) behaviors did not play a significant role in this process. In a second experience sampling study, involving 53 dual-earner couples with preschool children, detachment was associated with more affectionate interactions, which in turn, predicted lower actor, but not partner evening strain. These results suggest that detachment from work not only affects the working individual’s, but also their close partner’s the perception of their interactions, showing that detachment plays an important mediating role in the stress spillover and crossover process. This emphasizes the relevance of addressing interpersonal processes in the association between detachment and well-being

Predictors of psychological distress among divorced women in Iran

Previous research has consistently found that divorce is associated with psychological distress. This study expands existing research by considering age, education, employment, income, length of divorce, number of children, and economic hardship as predictors of postdivorce psychological distress among divorced women in Iran. This study examines 800 divorced women in Iran 30 to 48 years old who had been divorced for no more than 2 years. Results demonstrated that education, number of children, and economic hardship together predict 63.6% of the variance in psychological distress among divorced women. Economic hardship was found to be the strongest contributor. Recommendations for researchers and implications for clinicians are discussed

Increased Reward-Related Activation in the Ventral Striatum During Stress Exposure Associated With Positive Affect in the Daily Life of Young Adults With a Family History of Depression. Preliminary Findings

Background: Being the offspring of a parent with major depression disorder (MDD) is a strong predictor for developing MDD. Blunted striatal responses to reward were identified in individuals with MDD and in asymptomatic individuals with family history of depression (FHD). Stress is a major etiological factor for MDD and was also reported to reduce the striatal responses to reward. The stress-reward interactions in FHD individuals has not been explored yet. Extending neuroimaging results into daily-life experience, self-reported ambulatory measures of positive affect (PA) were shown to be associated with striatal activation during reward processing. A reduction of self-reported PA in daily life is consistently reported in individuals with current MDD. Here, we aimed to test (1) whether increased family risk of depression is associated with blunted neural and self-reported reward responses. (2) the stress-reward interactions at the neural level. We expected a stronger reduction of reward-related striatal activation under stress in FHD individuals compared to HC. (3) the associations between fMRI and daily life self-reported data on reward and stress experiences, with a specific interest in the striatum as a crucial region for reward processing. Method: Participants were 16 asymptomatic young adults with FHD and 16 controls (HC). They performed the Fribourg Reward Task with and without stress induction, using event-related fMRI. We conducted whole-brain analyses comparing the two groups for the main effect of reward (rewarded > not-rewarded) during reward feedback in control (no-stress) and stress conditions. Beta weights extracted from significant activation in this contrast were correlated with self-reported PA and negative affect (NA) assessed over 1 week. Results: Under stress induction, the reward-related activation in the ventral striatum (VS) was higher in the FHD group than in the HC group. Unexpectedly, we did not find significant group differences in the self-reported daily life PA measures. During stress induction, VS reward-related activation correlated positively with PA in both groups and negatively with NA in the HC group. Conclusion: As expected, our results indicate that increased family risk of depression was associated with specific striatum reactivity to reward in a stress condition, and support previous findings that ventral striatal reward-related response is associated with PA. A new unexpected finding is the negative association between NA and reward-related ventral striatal activation in the HC group

Relationship Processes in Understudied Samples: Implications for Relationship Functioning and Sexuality in Romantic Relationships

Relationship functioning can be investigated from different angles; next to investigating dyadic outcomes between couples we can also zoom into processes within subjects. Adopting a cultural lens adds another layer, as the cultural context influences norms around intimate relationships, and can be inspected using the framework of Bronfenbrenner´s (1977) ecological systems theory. In more collectivistic societies, for instance, the extended family is much more involved in decisions regarding the couple relationship, accompanied by more obligations and duties towards family members, and maintaining harmony within the community is much more important than the relationship satisfaction between spouses. It is therefore highly relevant to replicate existing evidence and extend these results beyond Western, Educated, Industrialized, Rich and Democratic (WEIRD) samples. This thesis aims at investigating predictors, correlates and processes in a non- Western sample and in intercultural couples, drawing on several relevant theories, in two empirical studies and a quantitative review. The empirical studies are based on a sample of 180 Iranian couples of which both partners provided weekly reports on their relational experiences during the past seven days, over the course of six consecutive weeks. In study 1, we tested a concurrent mediation model and demonstrated that drops in sexual satisfaction can explain variance of within-subject associations of conflict frequency with relationship satisfaction. In study 2, we found that both the absence or occurrence of sex, as well as cumulative sex frequency, predicted intimacy and relationship satisfaction in later weeks. The lagged model showed that sexual intercourse predicted prospective residualized change in womens´ perception of emotional intimacy one week later, which in turn predicted prospective residualized change in the partners´ relationship satisfaction two weeks later. These two studies provide further evidence for the tight interconnection of distressed interactions and sexual life in non-Western intimate relationships. The data also suggest these associations found in Western couples extend to non- Western couples in predominantly Muslim societies. Moving away from a single culture, in study 3 we considered couples with different socio-cultural backgrounds. Previous research found that couples with different socio- cultural backgrounds are less stable and less satisfied in their relationships than culturally homogeneous couples, due to additional stressors these couples face. We computed effect sizes comparing couples with different socio-cultural backgrounds and culturally homogeneous couples based on the studies included in this review. Our results suggest that controlling for socio-demographic variables that are specific to socio-culturally different couples decreases the gap in relationship functioning between the two groups. Besides the confirmation of several exchange theory components, we complement the underlying theory with our results in non-Western samples. Additionally, within-subject analysis showed considerable within- person variation implying complex relationship processes. All three studies underline that associations between indicators of relationship functioning in non-Western couples are similar to Western relationships. This supports the assumption that many intimacy-related aspects represent basic human needs. This dissertation further provides a comprehensive view on several indicators of relationship functioning by shedding light on predictors, processes and relationship outcomes within- and between-subjects

Associations between measures of emotion and familial dynamics in normative families with adolescents

The Family Life Scale (FLS), which includes the dimensions of Cohesion, Adaptability, Communication and Satisfaction, and two measures of emotion were applied to a German-speaking sample of adolescents and their parents in Switzerland. The main goal of the study was to assess the associations between the measures in order to increase our understanding of the dynamics involving emotional and familial factors, particularly in adolescents. Analyses revealed different patterns of association to emerge according to gender in both samples. Indeed, in girls, optimal family functioning was associated with Empathy, while similar trends were found in mothers. In boys, optimal family functioning was associated with Self-esteem, while similar trends were found in fathers. Overall, our data suggest that Empathy and Self-esteem play a significant role in the perception of family dynamics which may, reciprocally, affect emotional experiences in family members

Momentary Affective States Are Associated with Momentary Volume, Prospective Trends, and Fluctuation of Daily Physical Activity

Several interventions aiming to enhance physical activity in everyday life showed mixed effects. Affective constructs are thought to potentially support health behavior change. However, little is known about within-subject associations between momentary affect and subsequent physical activity in everyday life. This study analyzed the extent to which three dimensions of affective states (valence, calmness, and energetic arousal) were associated with different components of daily activity trajectories. Sixty-five undergraduates' students (Age: M = 24.6; SD = 3.2; females: 57%) participated in this study. Physical activity was assessed objectively through accelerometers during 24 h. Affective states assessments were conducted randomly every 45 min using an e-diary with a six-item mood scale that was especially designed for ambulatory assessment. We conducted three-level multi-level analyses to investigate the extent to which momentary affect accounted for momentary volume, prospective trends, and stability vs. fluctuation of physical activity in everyday life. All three affect dimensions were significantly associated with momentary activity volumes and prospective trends over 45 min periods. Physical activity didn't fluctuate freely, but featured significant autocorrelation across repeated measurements, suggesting some stability of physical activity across 5-min assessments. After adjusting for the autoregressive structure in physical activity assessments, only energetic arousal remained a significant predictor. Feeling energized and awake was associated with an increased momentary volume of activity and initially smaller but gradually growing decreases in subsequent activity within the subsequent 45 min. Although not related to trends in physical activity, higher valence predicted lower stability in physical activity across subsequent 45 min, suggesting more short-term fluctuations in daily activity the more participants reported positive affective valence. The current analyses afford interesting insight into within-subject associations between momentary affect and activity-trajectories in everyday life. Energetic arousal emerged as the only meaningful predictor of physical activity in daily life after adjusting for autoregression. A significant effect of valence on short-term activity fluctuations might indicate that activity interventions would benefit from taking into account enhancement of positive affective valence in everyday life. Moments of enhanced valence may scaffold attempts helping inactive people to get started with daily activities and overcome periods of inactivity in everyday life.publishe
