Positive Psychological States and Employee Creativity: The role of Ethical Leadership

This study explores a new theoretical model of employee creativity by investigating the impact of ethical leadership on creativity mediated by creative self-efficacy and psychological safety. Data collected from 200 supervisor–subordinate dyads in Pakistan reveal that ethical leadership is positively related to creativity. Further, psychological safety partially mediates the relationship between ethical leadership and creativity. However, creative self-efficacy is found insignificant in the relationship between ethical leadership and creativity. The study discusses research and practical implications of the proposed new theoretical framework with regard to employee creativity.     

Core Job Characteristic and Uncertainty Avoidance: Into the Black Box of Transformational Leadership Effect on Creativity

Drawing upon the job characteristic model and the “management of meaning” perspective, this study examines the process and conditions through which transformational leadership fosters employee creativity. Our results reveal that the effect of transformational leadership on creativity is mediated by employees’ perceptions of core job characteristics (variety, identity, significance, autonomy, feedback). This mediation effect is further moderated by employees’ uncertainty avoidance orientation. Specifically, transformational leaders foster creativity through followers’ perceptions of core job characteristics only among employees low on uncertainty avoidance. The association between enhanced job characteristics and creativity is more positive for employees with low uncertainty avoidance orientation than those with high uncertainty avoidance orientation. Implications and future research directions are discussed.     

Different roles of shared and vertical leadership in promoting team creativity: Cultivating and synthesizing team members’ individual creativity

Drawing on the componential model of creativity (Amabile), we examined how shared leadership and a formally appointed leader's transformational leadership jointly cultivate team creativity in two studies. We conducted an experiment with a sample of 109 undergraduate students (32 teams) enrolled in a business plan competition (Study 1) and a field survey based on multisource, time-lagged data collected from 251 full-time employees working on 64 research and development teams (Study 2). The results from both studies revealed that shared leadership enhanced team members’ individual creative self-efficacy and individual creativity, which in turn improved team creativity. Moreover, the results from Study 2 showed that a formally appointed leader's use of different transformational leadership behaviors had different impacts on individual and team creativity. Individual-focused transformational leadership strengthened the positive effect of shared leadership on team members’ average individual creativity, whereas group-focused transformational leadership facilitated the translation of teams with high average individual creativity into teams with high levels of team creativity. The theoretical and practical implications of the findings are discussed.     

A multiplex view of leadership structure in management teams

In the hope of complementing the structural perspective in upper echelon research and advancing a fine-grained understanding of dyadic leadership influence in management teams, the current study combines two types of intrateam structures—leadership network and friendship network—to create a multidimensional conceptualization of leadership structure in management teams. Specifically, we propose that management teams with a denser singular leadership network (i.e., a network consisting of many leadership ties that are not coupled with friendship ties) should have lower management team cohesion, which subsequently renders worse business unit performance. To contrast, management teams with a denser multiplex network (i.e., a network consisting of many leadership ties that are coupled with friendship ties) should have higher management team cohesion, which subsequently renders better business unit performance. Guided by structural contingency perspective, we further propose that management team task interdependence will strengthen team cohesion's positive impact on business unit performance. To test the hypothesized model, we collected team-level social network data and multiple-wave survey data from 697 managers nested in 148 hotels (i.e., 148 management teams) owned by a large hospitality company. We also obtained objective performance data for each hotel (i.e., occupancy percentage rate and revenue per available room per day) as the criterion measure. The data supported our hypotheses. The theoretical and practical implications of our findings are discussed.     

父母教养与MAOA基因rs6323多态性对学前儿童外化问题的共同作用

采用G×E交互作用的研究范式,以295名学前儿童（M=4.49）和其母亲、父亲作为研究对象,探讨母亲和父亲的教养方式与MAOA基因rs6323多态性对学前儿童外化问题行为的影响。结果发现：母亲、父亲教养方式和MAOA基因多态性对学前儿童外化问题行为的影响存在性别差异,预测男孩外化问题行为时,母亲和父亲教养方式的主效应显著,与MAOA基因多态性的交互作用不显著;在预测女孩外化问题行为时,父亲教养方式的主效应显著,母亲教养方式与MAOA基因多态性的交互作用显著,显著性区域分析发现,携带T等位基因的女孩更容易受到母亲消极教养的不利影响而产生更多外化问题行为,也更容易受到其积极教养的有利影响而减少外化问题行为,这一结果支持差别易感性理论模型。     

父母严厉管教与儿童问题行为的关系:儿童自我控制的中介作用

为探讨父母严厉管教、儿童自我控制与儿童问题行为间的关系,采用中文版亲子冲突解决策略量表、社会技能评定量表和儿童行为核查量表对济南市两所公立学校的1097名小学四到六年级儿童及其父母双亲进行测查。结果发现：（1）父母心理攻击和体罚与儿童自我控制均呈显著负相关,与儿童内化和外化问题行为均呈显著正相关,儿童自我控制与其内化和外化问题行为均呈显著负相关;（2）父亲心理攻击可以显著正向预测儿童内化和外化问题行为,母亲体罚可以显著正向预测儿童外化问题行为;（3）儿童自我控制在父亲心理攻击和母亲体罚与儿童内外化问题行为之间起中介作用,在母亲心理攻击和父亲体罚与儿童内外化问题行为关系间的中介作用不显著,中介作用模型不存在显著的儿童性别差异。综上,本研究发现父母严厉管教不仅直接影响儿童的内外化问题行为,而且会通过降低儿童自我控制水平间接导致儿童问题行为的增多。     

家庭社会经济地位对青少年问题行为的影响:父母情感温暖和公正世界信念的链式中介作用

为探讨家庭社会经济地位对青少年问题行为的影响及其作用机制,基于生物生态学理论,采用家庭社会经济地位评估、简式父母教养方式问卷、公正世界信念量表和长处与困难问卷对全国三大片区13所中学的1337名青少年（7~12年级）进行调查。结果表明：（1）家庭社会经济地位、父母情感温暖、公正世界信念和问题行为之间两两显著相关,且家庭社会经济地位能显著负向预测问题行为;（2）父母情感温暖和公正世界信念在家庭社会经济地位与问题行为之间起显著的中介作用。具体为三条中介路径：一是父母情感温暖的单独中介作用;二是公正世界信念的单独中介作用;三是父母情感温暖和公正世界信念的链式中介作用。本研究丰富了问题行为领域的研究成果,为预防和干预青少年问题行为提供了理论基础。     

时间定价与主观时间流逝速度感对利他行为的影响

采用筛选图片时间任务作为被试利他意愿的指标,考察在两种主观时间流逝速度（时间飞逝和时间缓慢）条件下,被试（时间定价组和非时间定价组）对利他行为的影响。结果发现,非时间定价组在时间飞逝和缓慢条件下利他行为差异不显著,但是时间定价组在时间飞逝条件下比在时间缓慢条件下利他行为时间明显较短。结果表明,时间定价组在时间飞逝条件下充分显现时间的价值,减少利他时间,而在时间缓慢条件下,在可接受的时间成本范围内,被试表现出较为乐于助人,证实了主观时间流逝速度会对个体利他行为产生影响。     

Predicting bulimic symptoms: an interactive model of self-efficacy, perfectionism, and perceived weight status

An interactive model of perfectionism, perceived weight status, and self-efficacy was tested on 406 women to predict the bulimic symptoms of binge eating and inappropriate compensatory behaviors separately. This longitudinal study assessed hypothesized vulnerabilities of high perfectionism and low self-efficacy and the stressor of feeling overweight at Time 1 and then gathered weekly assessments of binge eating, vomiting, laxative use, fasting, and diet pill use for 11 weeks. As predicted, results showed that perfectionism, weight perception, and self-efficacy interacted to prospectively predict binge eating. In particular, women high in perfectionism who felt they were overweight and who had low self-efficacy reported the most number of weeks of binge eating. This interactive model did not predict inappropriate compensatory behaviors. Future directions and clinical implications are discussed.
