药物成瘾者决策缺陷的特征、机制及干预

药物成瘾者存在决策缺陷, 并表现出冲动性、风险寻求、奖赏失调、躯体内感信号缺失等特征。神经影像学研究表明药物滥用导致成瘾者背外侧前额皮层、前扣带回、眶额叶皮层、腹内侧前额皮层、杏仁核、脑岛等脑区受损, 这些损伤是引发其决策缺陷的主要原因。认知训练有利于提高个体的决策能力, 如目标管理训练和正念冥想等可以增强个体工作记忆、促进自我觉察和以目标为导向的行为; 而非侵入性脑刺激则可以直接改变与成瘾者决策相关脑区的激活状态, 从而提升与决策相关的认知功能。总体而言, 未来认知训练和非侵入性脑刺激在成瘾干预方面仍有广阔的拓展空间。     

Transitions in sleep problems from late adolescence to young adulthood: A longitudinal analysis of the effects of peer victimization

Adolescence is a developmental period with high vulnerability to sleep problems. However, research identifying distinct patterns and underlying determinants of sleep problems is scarce. This study investigated discrete subgroups of, changes in, and stability of sleep problems. We also examined whether peer victimization influenced sleep problem subgroups and transitions in patterns of sleep problems from late adolescence to young adulthood. Sex differences in the effects of peer victimization were also explored. In total, 1,455 male and 1,399 female adolescents from northern Taiwan participated in this longitudinal study. Latent transition analysis was used to examine changes in patterns of sleep problems and the effects of peer victimization on these changes. We identified three subgroups of sleep problems in males and two in females, and found that there was a certain level of instability in patterns of sleep problems during the study period. For both sexes, those with greater increases in peer victimization over time were more likely to change from being a good sleeper to a poor sleeper. The effects of peer victimization on baseline status of sleep problems, however, was only significant for males, with those exposed to higher levels of peer victimization more likely to be poor sleepers at baseline. Our findings reveal an important role of peer victimization in predicting transitions in patterns of sleep problems. Intervention programs aimed at decreasing peer victimization may help reduce the development and escalation of sleep problems among adolescents, especially in males.

     

Divergent thinking and constructing episodic simulations

Divergent thinking likely plays an important role in simulating autobiographical events. We investigated whether divergent thinking is differentially associated with the ability to construct detailed imagined future and imagined past events as opposed to recalling past events. We also examined whether age differences in divergent thinking might underlie the reduced episodic detail generated by older adults. The richness of episodic detail comprising autobiographical events in young and older adults was assessed using the Autobiographical Interview. Divergent thinking abilities were measured using the Alternative Uses Task. Divergent thinking was significantly associated with the amount of episodic detail for imagined future events. Moreover, while age was significantly associated with imagined episodic detail, this effect was strongly related to age-related changes in episodic retrieval rather than divergent thinking.     

The influence of family context on life,educational and occupational ideal among middle school students in China

This study examined the relationship between family context of middle school students on their educational and occupational ideals. Middle school students (N = 2000) responded to questions assessing family location, family structure, parental educational level and family economic status, as well as to the Middle School Students' Ideals Questionnaire. Multivariate analysis of variance indicated that life, educational and occupational ideals of female students and students in lower grades were higher than that of male students and students in higher grades. Regression analysis indicated that paternal education level have a positive association with educational and occupational ideals, but not life ideals, and family economic status have a positive relation to life ideals, but not educational and occupational ideals. Moreover, the interaction between family economic status and family location has a negative association with students' life, educational and occupational ideals. These results suggest that different factors predicted different ideals of adolescents, and that family economic status had a negative moderating effect on the relationship between family location and ideals of students.     

International students’ attachment and psychological well-being: the mediation role of mental toughness

This study examined the relationships of adult attachment, mental toughness (MT), and psychological well-being of international students. We hypothesized that attachment anxiety and avoidance would predict psychological well-being outcome variables and that MT would mediate the attachment-wellbeing links. The participants were 217 international students from a large public college in the United States. Structure Equation Modeling analyses were used to examine the proposed mediation effects. Result showed that MT functioned as a mediator for the paths between attachment anxiety and the two well-being latent variables of psychological distress and life satisfaction. On the other hand, attachment avoidance was found to have a more direct effect on adjustment difficulties without going through MT. Limitation and counseling implications are discussed.     

Acceptance of Illness Among Patients Pursuing Transplantation or Left Ventricular Assist Device

Acceptance of illness is related to better mental health among patients with chronic illness; however, this construct has not been evaluated as part of routine transplantation evaluations. The purpose of this study was to create a brief measure of acceptance of illness for patients pursuing organ transplantation and examine how acceptance is related to distress. Retrospective medical record reviews were conducted for 290 patients who completed a routine psychosocial evaluation prior to transplant listing which included the Illness Acceptance Scale (IAS). Internal consistency for the IAS was excellent (Cronbach’s alpha?=?.92). Illness acceptance was negatively correlated with depression, anxiety, and catastrophizing and was not related to health literacy or health numeracy. The IAS is a reliable and valid measure for patients who are pursuing thoracic transplant or left ventricular assist device. Clinicians may want to screen transplant candidates for illness acceptance and refer those with lower levels to psychological interventions.

     

An analysis of the changing doctor-patient relationship in China

As China is undergoing marketization and privatization, the doctor-patient relationship (DPR) is changing, posing numerous social problems such as a trust crisis. In this article, the authors look at the characteristics of the DPR, and then present an historical account of the changing features of the Chinese DPR. In the final section, they explain how Chinese traditional culture is important for rebuilding the DPR in reform-era China and make suggestions for its health care reform.     

Benefitting from a different perspective: The effect of a complementary matching of psychological distance and habitual perspective on emotion regulation

Psychological distance in terms of its purpose as a psychological adjustment is currently not well understood. Some researchers claim that psychological distance serves as an emotion regulator, while others argue that psychological distance has the reverse effect, leading to cognitive avoidance and rumination. To elucidate upon this discrepancy, we propose that a complementary matching of psychological distance to one's habitual psychological distance perspective may lead to better emotion regulation when compared to the original perspective (i.e. fixing on either psychological immersion or distance). This study hypothesizes that a complementary matching of psychological distance to one's habitual perspective generally leads to better emotion regulation; specifically, individuals with high avoidant attachment, who habitually distance themselves from their experiences, may benefit from psychological immersion, while individuals with high anxious attachment, who habitually immerse themselves in their experiences, may benefit from psychological distancing. A total of 83 participants completed measures of adult attachment orientations; read a conflict scenario, triggering their attachment systems; and then rewrote that scenario using designated pronouns, thereby employing psychological immersion or psychological distance. Participants in the self‐immersed condition were asked to write from the first‐person perspective, whereas those in the self‐distancing condition were asked to write from the third‐person perspective. The results support our hypothesis of a complementary matching of psychological distance and habitual perspective.     

Fathering Self-Efficacy, Marital Satisfaction and Father Involvement in Hong Kong

We examined the predictability of fathering self-efficacy and marital satisfaction on father involvement. The moderating effect of marital satisfaction on the relationship between father efficacy and father involvement was also explored. A cross-sectional survey was conducted using the convenience sampling method. A total of 2,029 valid questionnaires were collected from fathers with children aged 2–6 from 48 nurseries in Hong Kong. The fathers’ mean age is 39.1. 72.9 % of the fathers graduated from secondary school and 86 % had full-time jobs. Measures including self-efficacy subscale in the Parenting Sense of Competency Scale, the Index of Marital Satisfaction, the Inventory of Father Involvement were adopted in the present study. Hierarchical regression analyses showed that fathering self-efficacy and marital satisfaction were significant positive predictors of father involvement, whereas marital satisfaction moderated the effect of fathering self-efficacy on father involvement. It is thus important to improve martial satisfaction and enhance fathering self-efficacy for promoting father involvement. To gain a more comprehensive picture, future studies of father involvement may benefit by adopting a longitudinal research design, including the mothers and children as informants, and addressing other parenting correlates such as parenting stress and spousal support.
