Does Therapeutic Repetitive Transcranial Magnetic Stimulation Cause Cognitive Enhancing Effects in Patients with Neuropsychiatric Conditions? A Systematic Review and Meta-Analysis of Randomised Controlled Trials

Repetitive transcranial magnetic stimulation (rTMS) is increasingly used as a therapeutic intervention for neuropsychiatric illnesses and has demonstrated efficacy for treatment of major depression. However, an unresolved question is whether a course of rTMS treatment results in effects on cognitive functioning. In this systematic review and meta-analysis we aimed to quantitatively determine whether a course of rTMS has cognitive enhancing effects. We examined cognitive outcomes from randomised, sham-controlled studies conducted in patients with neuropsychiatric conditions where rTMS was administered to the dorsolateral prefrontal cortex (DLPFC) across repeated sessions, searched from PubMed/MEDLINE and other databases up until October 2015. Thirty studies met our inclusion criteria. Cognitive outcomes were pooled and examined across the following domains: Global cognitive function, executive function, attention, working memory, processing speed, visual memory, verbal memory and visuospatial ability. Active rTMS treatment was unassociated with generalised gains across the majority of domains of cognitive functioning examined. Secondary analyses revealed a moderate sized positive effect for improved working memory in a small number of studies in patients with schizophrenia (k = 3, g = 0.507, 95 % CI = [0.183–0.831], p < .01). Therapeutic rTMS when administered to the DLPFC in patients with neuropsychiatric conditions does not result in robust cognitive enhancing effects.     

Economic Pressure,Individual and Family Processes,and Children’s Reticence in Romanian Families

Using Conger’s family stress model as a theoretical framework, a series of mediated associations among economic hardship, perceived economic pressure, parental depression, marital conflict, psychologically controlling parenting, and children’s reticent behaviors in Romanian families were studied. The sample consisted of 121 Romanian mothers and fathers of 4–5-year-old children. Children’s kindergarten teachers living in urban and rural locations evaluated child reticence. Findings generally support the family stress model. Structural equation modeling showed that after controlling for living in a rural location, economic pressure was indirectly linked with marital conflict through depression. Depression was indirectly related to psychological control through marital conflict, and marital conflict was indirectly linked to child reticence through psychological control. Directions for future research and recommendations for interventions and public policy are described.     

Perceived ethical leadership: Its moderating influence on employees’ organisational commitment and organisational citizenship behaviours

This study investigated the extent to which employees’ perception of ethical leadership moderated their organisational commitment and organisational citizenship behaviour. A non-probability purposive sample (N = 839; females = 32%) of employees in a railway organisation in the Democratic Republic of Congo (DRC) participated in the study. They completed the following measures: the Organisational Commitment Scale (OCS), the Organisational Citizenship Behaviour Questionnaire (OCBQ) and the Ethical Leadership Scale (ELS). Stepwise hierarchical regression analysis was utilised to determine the influence of employees’ perceptions of the relationships between their self-reported organisational commitment and organisational citizenship behaviour. The results indicated employee perceptions of the integrity, fairness and honesty aspects of ethical leadership to explain their affective, continuance and normative aspects of organisational commitment and organisational citizenship behaviour. The results also showed that employee perceptions of high ethical leadership influenced their willingness to engage in positive organisational commitment such as psychological attachment, work continuance, normative commitment and also their organisational citizen behaviours such as altruism, conscientiousness, courtesy and civic virtue. By implication, leaders with high ethical conduct have the potential to positively stimulate the commitment of employees towards supporting the organisational values and mission.     

Workplace ethics culture and work engagement: The mediating effect of ethical leadership in a developing world context

This study examined the mediating effect of ethical leadership on the relationship between workplace ethics culture and work engagement among employees in a railway transport organisation in the Democratic Republic of the Congo (DRC). The sample consisted of permanently employed staff in a railway organisation in the DRC (n = 839; females = 32%). The employees were required to complete the Ethical Leadership Scale (ELS), the Ethical Corporate Virtue model (ECV) and the Utrecht Work Engagement Scale (UWES). Mediating regression analyses were conducted to predict work engagement from workplace ethics culture, partialling out ethical leadership. The results show that workplace ethics culture had a significantly positive effect on work engagement. The results further indicated that workplace ethics culture, through the mediation of perceived ethical leadership, had a significantly positive effect on the work engagement dimensions of vigour, dedication and absorption. The findings provide evidence that ethical leadership plays a crucial role in shaping workplace ethics culture and employees’ level of work engagement in an emerging country work setting.     

For richer,for poorer: Financial behaviors,power (im)balance,and relational aggression among different-gender newlyweds in the U.S.

Guided by an intersectional feminism framework, we used three-wave, dyadic survey data from a nationally representative sample of 1625 U.S. different-gender newlywed couples to test three research questions. First, as balanced power is considered a key concept for relational well-being in feminism, we examined developmental trajectories in husbands' and wives' perception of power (im)balance. Second, considering money as a major influence on power and aggression, we examined how financial behaviors relate to power (im)balance and in turn relational aggression—a type of intimate partner violence that is controlling and manipulative in nature. Third, informed by the intersectionality between gender and socioeconomic status (SES), we examined gender differences and SES disparities in the associations among financial behaviors, developmental trajectories of perception of power (im)balance, and relational aggression. Our findings demonstrate that newlywed different-gender couples are experiencing power struggles, where two partners diminish each other's influence over time. We also found that healthy financial behaviors are associated with balanced power and, in turn, less relational aggression (especially for wives and in lower-SES households). Taken collectively, we continue calling for efforts to facilitate money management skills and promote balanced marital power.     

Case illustration: Moving along…and,is change gradual or sudden?

A sequence of analytic sessions of a professional woman in her forties is used to illustrate the moving along process. The material shows a gradual change, where the patient's experience of her sense of agency is altered through a particular kind of interactive sequence. The example is intended to make it clear that the group's view of how change occurs is not strictly or primarily in terms of sudden changes, and that the problem of assessing moments of meeting as well as quantitative and qualitative shifts is one with which the group continues to struggle. © 1998 Michigan Association for Infant Mental Health     

Does Cooperation in the Laboratory Reflect the Operation of a Broad Trait?

The Dictator Game, a face valid measure of altruism, and the Trust Game, a face valid measure of trust and trustworthiness, are among the most widely used behavioural measures in human cooperation research. Researchers have observed considerable covariation among these and other economic games, leading them to assert that there exists a general human propensity to cooperate that varies in strength across individuals and manifests itself across a variety of social settings. To formalize this hypothesis, we created an S‐1 bifactor model using 276 participants' Dictator Game and Trust Game decisions. The general factor had significant, moderate associations with self‐reported and peer‐reported altruism, trust, and trustworthiness. Thus, the positive covariation among economic games is not reducible to the games' shared situational features. Two hundred participants returned for a second session. The general factor based on Dictator Game and Trust Game decisions from this session did not significantly predict self‐reported and peer‐reported cooperation, suggesting that experience with economic games causes them to measure different traits from those that are reflected in self‐assessments and peer‐assessments of cooperativeness. © 2018 European Association of Personality Psychology
