Longitudinal changes in marital satisfaction during middle age in Taiwan

The current 8‐year panel study explored changes in marital satisfaction among 614 married middle‐aged persons with seventh‐grade children. It also examined how individual health (physical health and depressive moods) and role changes (parenting transitions and life stress) were related to trajectories of marital satisfaction and investigated the buffering effect of family cohesion on these associations. Growth curve analyses show an inverted‐U shape in marital satisfaction during middle age. This indicates that regardless of the gender or age of the respondents, marital satisfaction among middle‐aged adults increased when their children were in the 9^th and 12^th grade, and then declined when their children were in their sophomore year of college. Declining physical health and an increase in depressive moods were related to a drop in marital satisfaction. Stressful events in midlife had negative effects on marital satisfaction, and family cohesion served as a buffer to mitigate the adverse impact of life stress on marital satisfaction. Overall, these results highlight the role of adolescent children in understanding why marital satisfaction changes among middle‐aged parents and emphasize the importance of health and life stress in relation to midlife marital satisfaction. These findings are discussed with life course perspectives and Taiwanese cultural values in relation to familism and academic achievement among children.     

Episodic memory function is affected by lifestyle factors: a 14-year follow-up study in an elderly population

Understanding the relationship between memory function and lifestyle offers great opportunities for promoting beneficial lifestyle choices to foster healthy cognitive aging and for the development of intervention programs for older adults. We studied a cohort of older adults (age 65 and older) enrolled in the Longitudinal Aging Study Amsterdam, an ongoing prospective population-based research project. A total of 1,966 men and women participated in an episodic memory test every 3 years over a period of 14 years. Lifestyle habits were repeatedly assessed using self-report measures. Physical activity, light-to-moderate alcohol consumption, difficulties staying asleep, and social engagement were associated with better memory function over the course of 14 years. In contrast, smoking and long sleep duration were associated with worse memory function. These findings suggest that certain lifestyle factors can have long-term protective or harmful effects on memory function in aging individuals.     

A Hierarchical Rater Model for Longitudinal Data

Research studies in psychology and education often seek to detect changes or growth in an outcome over a duration of time. This research provides a solution to those interested in estimating latent traits from psychological measures that rely on human raters. Rater effects potentially degrade the quality of scores in constructed response and performance assessments. We develop an extension of the hierarchical rater model (HRM), which yields estimates of latent traits that have been corrected for individual rater bias and variability, for ratings that come from longitudinal designs. The parameterization, called the longitudinal HRM (L-HRM), includes an autoregressive time series process to permit serial dependence between latent traits at adjacent timepoints, as well as a parameter for overall growth. We evaluate and demonstrate the feasibility and performance of the L-HRM using simulation studies. Parameter recovery results reveal predictable amounts and patterns of bias and error for most parameters across conditions. An application to ratings from a study of character strength demonstrates the model. We discuss limitations and future research directions to improve the L-HRM.     

Leadership behavior changes following a theory‐based leadership development intervention: A longitudinal study of subordinates’ and leaders’ evaluations

The aim was to evaluate effects of leadership courses based on the developmental leadership model at the leadership behavioral level. A longitudinal design was employed with assessments before, one and six months after the leadership courses. The sample consisted of 59 leaders who made self‐ratings and were rated by at least three subordinates on each occasion. Leadership behaviors were measured with the Developmental Leadership Questionnaire (DLQ). A limited increase of favorable leadership behaviors and a significant reduction of unfavorable leadership behaviors were found, particularly according to the subordinates’ ratings. A cluster analysis yielded three meaningful leader profiles and showed that this pattern was found in all three profiles, irrespective of how favorably they were rated before the onset of the intervention.     

Genetic and Environmental Pathways Underlying Personality Traits and Perceived Stress: Concurrent and Longitudinal Twin Studies

The present study examined the genetic and environmental etiology underlying the Big Five personality traits and perceived stress, concurrently and longitudinally. In study 1, we used the twin sample from the National Longitudinal Study of Adolescent to Adult Health (Add Health IV) data. The results indicated that about 70% of the association between the Big Five personality traits and perceived stress was due to genetic influences. In study 2, we used the twin sample from the Midlife in the United States Survey (MIDUS I and II) to examine the genetic and environmental influences underlying the longitudinal relations between the Big Five personality traits and perceived stress. The results suggested that continuity in perceived stress was primarily accounted for by genetic influences, and changes in perceived stress were mainly due to nonshared environmental influences. The continuity in the association between the five personality traits and perceived stress was largely accounted for by genetic factors, and nonshared environmental factors made greater contributions to changes in the association between personality traits and perceived stress. Among the Big Five personality traits, the genetic components in conscientiousness and neuroticism made substantial contributions to the genetic link between personality traits and perceived stress across both studies.

流动性、教育安置方式和心理弹性对流动儿童孤独感的影响:一项追踪研究

采用潜变量增长模型对426名流动儿童进行四次追踪测查,旨在考察流动儿童孤独感的变化趋势,探索不同流动性和教育安置方式的流动儿童孤独感变化的差异性以及心理弹性对孤独感变化的促进性作用。结果发现：（1）流动儿童的孤独感呈线性下降趋势;（2）打工子弟学校流动儿童的孤独感起始水平显著高于公立学校流动儿童;流动性高的儿童的孤独感起始水平高于流动性低的儿童,但流动性和教育安置方式对孤独感的发展趋势没有显著预测作用;（3）对于流动儿童来说,较高的心理弹性水平不仅能显著预测更低的孤独感起始水平,同时也能显著预测更快的孤独感的下降速率。本研究启示,增加进入公立学校学习的机会、降低流动频率和提升心理弹性对降低流动儿童的孤独感水平具有重要的意义。     

初中生应对方式、压力对社会适应的影响:纵向中介模型

青春期的适应问题及其影响因素历来是研究者关注的焦点。本研究对369名初中生从初一到初三的应对方式、压力、社会适应进行了四次调查,通过纵向中介模型考察应对方式、压力对社会适应的影响。结果表明：初一时期的积极应对方式能够直接提高初三时期的积极适应水平,直接降低消极适应水平;初一时期的消极应对方式会通过提高后期的压力间接提高初三时期的消极适应水平。     

Lessons Learned from the Parents Matter! Program

We present a discussion of some of the lessons the investigators learned during the development and implementation phases of the Parents Matter! Program (PMP). Lessons were learned that are relevant to various groups involved in large scale, multi-site, community-based intervention studies: investigators, community leaders, community members, project staff, and participants. Specific lessons learned include: (1) forge collaboration early: (2) maintain communication; (3) clearly delineate policies and procedures; and (4) develop proactive strategies. We also include a list of important questions to consider when contemplating similar projects.     

Development of infant crying behavior: A longitudinal case study

This study documents the development of infant crying behavior during the second half of the first year (across a key developmental transition). Two female infants were observed twice a month for 6 months when the infants were between 7 and 14 months of age. The infants exhibited crying behavior that seemed to become more sophisticated with increasing age. This marked a proactive stance in communicating with the mother on the part of the infant. Interestingly, at 11–12 months, “fake crying” was observed during a naturalistic interaction with the mother. This implied that deceptive infant behavior could be seen at quite an early stage.     

Perceiving the Present: Systematization of Illusions or Illusion of Systematization?

Mark Changizi et al. (2008) claim that it is possible systematically to organize more than 50 kinds of illusions in a 7 × 4 matrix of 28 classes. This systematization, they further maintain, can be explained by the operation of a single visual processing latency correction mechanism that they call “perceiving the present” (PTP). This brief report raises some concerns about the way a number of illusions are classified by the proposed systematization. It also poses two general problems—one empirical and one conceptual—for the PTP approach.
