Longitudinal trajectories of maternal parenting stress in Korean families: Children's executive function and school adjustment

A majority of mothers experience parenting stress in daily life; however high levels of maternal stress have been recognized as a risk factor for children's developmental outcomes. We examined trajectories of maternal parenting stress across childhood, and their longitudinal relations to children's executive function and school adjustment. Data were drawn from the Panel Study on Korean Children (PSKC), which included 1754 mothers across five waves measured at children ages 3, 4, 5, 6, and 7 (boys = 51%). Results of Latent Growth Curve Modeling (LGCM) revealed that, on average, maternal parenting stress decreased over time, but there were significant variabilities in the initial levels at age 3 and changes across early through middle childhood. High initial levels of stress and an increase in maternal parenting stress over time were associated with lower executive function at age 7 in planning-organizing and attention concentration. An increment in maternal parenting stress over time was related to poorer school adjustment at age 7, measured by classroom behavior, positive approach to learning, and child-peer and child-teacher relationships. These findings support cultural commonality and may contribute to the instantiation of culturally universal, early preventions and interventions to support mothers’ mental health. Efforts aimed at reducing maternal parenting stress early in development may promote better long-term developmental outcomes, including executive functioning and school adjustment of children in their first year of elementary school.     

Intimate partner violence and preschool self-regulation: Examining the role of maternal emotion socialization in Black families

The ways that parents respond to children's negative emotions shape the development of self-regulation across early childhood. The objective of this study was to examine child self-regulation in the context of intimate partner violence (IPV) exposure in a sample of Black, economically marginalized mothers and their young children (aged 3–5 years, N = 99). The study investigates the conditional effects of emotion socialization practices that (1) encourage expression of and problem-solving around negative affect (“supportive”), and (2) encourage suppression of affective displays (“suppressive”) on children's self-regulation. We found a significant association between higher child self-regulation and supportive parental reactions in the context of psychological IPV. We also found a significant association between higher child self-regulation and suppressive parental reactions in the context of psychological IPV. Our findings are consistent with prior research suggesting Black parents who teach varied strategies for emotional expression may promote children's adaptation in high-stress family environments. Macrosystem factors such as systemic racism and discrimination as well as the threat of family violence may shape how parents approach emotion socialization and the teaching of affective self-expression and self-regulation.     

Object relations couple therapy for a married Korean man with sexual dysfunction

This study uses James Donovan's object relations couple therapy to examine the triangle of focus (conflict style, couple characteristics, and family of origin) and triangle of conflict (anxiety, defence mechanisms, and hidden emotions) of a married Korean man with sexual dysfunction (reduced sexual desire, premature ejaculation, and erectile dysfunction). This qualitative study uses thematic analysis to identify, describe, and analyse a family therapy case study. The aim of this study is to examine the couple's interaction patterns and experiences of conflicts related to the husband's erectile dysfunction. The researchers induced patterns or topics by repeatedly reading and comparing the data. Then, they textualised and analysed the relevant data. To ensure the reliability and validity of the data analysis, the researchers conducted shared coding sessions to review and discuss the initial codes and the generated main themes and subthemes, triangulating the qualitative data. Findings show that a newlywed husband's sexual dysfunction is associated with his emotional resistance towards his wife's unilateral pursuit over their sexual relationship and the negative emotions triggered by their dysfunctional interactions. Further, couple characteristics, conflict style (dysfunctional interactions), and family-of-origin factors (transference and patrilocality) influenced their sexual relationship. Therefore, therapists who counsel Korean couples with sexual issues may pay attention to the sociocultural factors, interactional patterns, and psychological factors associated with unresolved issues with their families of origin.     

Nonstationary Binary Choice

This paper develops an asymptotic theory for time series binary choice models with nonstationary explanatory variables generated as integrated processes. Both logit and probit models are covered. The maximum likelihood (ML) estimator is consistent but a new phenomenon arises in its limit distribution theory. The estimator consists of a mixture of two components, one of which is parallel to and the other orthogonal to the direction of the true parameter vector, with the latter being the principal component. The ML estimator is shown to converge at a rate of n^3/4 along its principal component but has the slower rate of n^1/4 convergence in all other directions. This is the first instance known to the authors of multiple convergence rates in models where the regressors have the same (full rank) stochastic order and where the parameters appear in linear forms of these regressors. It is a consequence of the fact that the estimating equations involve nonlinear integrable transformations of linear forms of integrated processes as well as polynomials in these processes, and the asymptotic behavior of these elements is quite different. The limit distribution of the ML estimator is derived and is shown to be a mixture of two mixed normal distributions with mixing variates that are dependent upon Brownian local time as well as Brownian motion. It is further shown that the sample proportion of binary choices follows an arc sine law and therefore spends most of its time in the neighborhood of zero or unity. The result has implications for policy decision making that involves binary choices and where the decisions depend on economic fundamentals that involve stochastic trends. Our limit theory shows that, in such conditions, policy is likely to manifest streams of little intervention or intensive intervention.
