Nonlinear Predictive Models for Multiple Mediation Analysis: With an Application to Explore Ethnic Disparities in Anxiety and Depression Among Cancer Survivors

Mediation analysis allows the examination of effects of a third variable (mediator/confounder) in the causal pathway between an exposure and an outcome. The general multiple mediation analysis method (MMA), proposed by Yu et al., improves traditional methods (e.g., estimation of natural and controlled direct effects) to enable consideration of multiple mediators/confounders simultaneously and the use of linear and nonlinear predictive models for estimating mediation/confounding effects. Previous studies find that compared with non-Hispanic cancer survivors, Hispanic survivors are more likely to endure anxiety and depression after cancer diagnoses. In this paper, we applied MMA on MY-Health study to identify mediators/confounders and quantify the indirect effect of each identified mediator/confounder in explaining ethnic disparities in anxiety and depression among cancer survivors who enrolled in the study. We considered a number of socio-demographic variables, tumor characteristics, and treatment factors as potential mediators/confounders and found that most of the ethnic differences in anxiety or depression between Hispanic and non-Hispanic white cancer survivors were explained by younger diagnosis age, lower education level, lower proportions of employment, less likely of being born in the USA, less insurance, and less social support among Hispanic patients.     

A Typology of Interactional Patterns Between Youth and Their Stepfathers: Associations with Family Relationship Quality and Youth Well‐Being

Stepfamilies are an increasingly common family form, many of which are headed by a resident mother and stepfather. Stepfather–child relationships exert notable influence on stepfamily stability and individual well‐being. Although various stepfather roles have been observed, more research is warranted by which stepfather–child interactions are explored holistically and across a variety of life domains (e.g., recreational, personal, academic, and disciplinary). Thus, the primary purpose of the current study is to explore varying interactional patterns between youth and their stepfathers. A latent class analysis is conducted using a representative sample of 1,183 youth (53% female; mean age = 15.64 years, SD = 1.70 years; 62% non‐Hispanic White) residing in mother–stepfather families from Wave I of the National Longitudinal Study of Adolescent to Adult Health. Latent‐class enumeration processes support a four‐class solution, with latent classes representing inactive, academically oriented, casually connected, and versatile and involved patterns of youth–stepparent interaction. Notable differences and similarities are evident across patterns with respect to family relationship quality, youth well‐being, and socio‐demographic characteristics. Differences are most stark between the inactive and versatile and involved patterns. Ultimately, the results showcase notable variation in youth–stepparent interactional patterns, and one size does not necessarily fit all stepfamilies. Family practitioners should be mindful of variation in youth–stepparent interactional patterns and assist stepfamilies in seeking out stepparent–child dynamics that are most compatible with the needs and dynamics of the larger family system.     

The role of severity and intentionality in the intensity of Schadenfreude attribution: A developmental study of Danish children

Understanding envy and schadenfreude requires complex interpersonal social cognitive abilities, such as social comparison and evaluating the Self, but also understanding agency and intentionality. Previous studies of children's development of envy/schadenfreude addressed whether children understand and experience schadenfreude as opposed to compassion/sympathy or whether children's attribution of schadenfreude is a consequence of envy provoked by a disadvantageous social comparison. In this study, we take a step further and investigate the roles that agency and severity of the damage play in mediating children's attribution of schadenfreude. The participants were 144 Danish children aged 3–9 years divided into two age groups. Children were presented with eight stories supported by pictures showing intentional versus accidental and irreparable versus reparable damage to envied objects. The results show that the intensity of envy/schadenfreude, as well as the happy victimizer phenomenon, varies depending on the severity of damage, agency and intentionality. When damage is accidental, schadenfreude is expressed with less intensity compared to when damage is intentional (led by an agent). When damage is irreparable, children attribute less intense feelings of schadenfreude compared to when it is reparable. In addition, only the older children expressed reparable damage carrying more intense schadenfreude and only in the accidental condition. In general, children consider intentional and reparable damage more intense than accidental and irreparable damage, and this is mediated by age. The results are important for understanding the developmental trajectory of children's complex emotions and for educational programmes directed towards supporting this development.     

Profiting from poverty

We consider whether and under what conditions it is morally illicit to profit from poverty. We argue that when profit counterfactually depends on poverty, the agent making the profit is morally obliged to relinquish it. Finally, we argue that the people to whom the profit should be redirected are those on whom it counterfactually depends.     

Family Resource Allocation after Firstborns Leave Home: Implications for Secondborns' Academic Functioning

This study assessed secondborn adolescents' perceptions of changes in the allocation of family resources following their firstborn siblings' departure from home after high school, and whether perceived changes were related to changes over 1 year in secondborns' academic functioning. Participants were secondborn siblings (mean age = 16.58, SD = 0.91) from 115 families in which the older sibling had left the family home in the previous year. Allocation of resources was measured via coded qualitative interviews. Most (77%) secondborns reported increases in at least one type of family resource (i.e., parental companionship, attention, material goods), and many reported an increase in multiple types of resources in the year following their older sibling's departure. Consistent with resource dilution theory, perceptions of increases in fathers' companionship, fathers' attention, and mothers' companionship were related to improvements over time in secondborns' academic functioning.     

Divorce Stress,Stepfamily Stress,and Depression among Emerging Adult Stepchildren

Several decades of research have shown that parental divorce can be a stressful experience for children and may lead to depression and other negative outcomes. Similarly, research has highlighted the stressors often induced by stepfamily formation and their effects on children. Although singular family transitions can exert influence, few studies explore how the combined stress from two family transitions may interact to influence long-term outcomes. Our study addresses this gap by using national data from 1142 respondents who experienced parental divorce and a subsequent transition to stepfamily life. Congruent with prior research, we find that retrospective reports of divorce and stepfamily stress is associated with higher depressive symptoms in emerging adults (18–30 years of age). We also find that stress induced by parental divorce and subsequent stepfamily formation significantly interact to increase depressive symptoms in this population. The research and clinical implications of our findings are discussed.     

To defer or to stand up? How offender formidability affects third party moral outrage

According to models of animal behavior, the relative formidability of conspecifics determines the utility of deferring versus aggressing in situations of conflict. Here we apply and extend these models by investigating how the formidability of exploiters shapes third party moral outrage in humans. Deciding whether to defer to or stand up against a formidable exploiter is a complicated decision as there is both much to lose (formidable individuals are able and prone to retaliate) and much to gain (formidable individuals pose a great future threat). An optimally designed outrage system should, therefore, be sensitive to these cost- benefit trade-offs. To test this argument, participants read scenarios containing exploitative acts (trivial vs. serious) and were presented with head-shot photos of the apparent exploiters (formidable vs. non-formidable). As predicted, results showed that, compared to the non- formidable exploiter, the formidable exploiter activated significantly more outrage in male participants when the exploitative act was serious. Conversely, when it was trivial, the formidable exploiter activated significantly less outrage in male participants. However, these findings were conditioned by the exploiters' perceived trustworthiness. Among female participants, the results showed that moral outrage was not modulated by exploiter formidability.
