相对于传统的离散作答数据, 作答时间作为连续数据, 可以提供更多信息。改变点分析(change point analysis)技术在心理和教育领域是一个比较新的技术。本文一方面对改变点分析在心理测量领域的应用进行了一个综合的总结和分析; 另一方面, 将基于作答数据的两种改变点分析统计量推广到作答时间数据, 将改变点分析技术应用到测验异常作答模式：加速作答speededness的检测上。采用两种检验方法：似然比检验和Wald检验, 分别在已知和未知项目参数的条件下, 实现异常作答模式的检测。结果表明, 所采用的方法对于加速作答行为的检测具有很高的检验力, 同时能够很好的控制I类错误率。实证数据分析进一步表明本文中所使用的方法具有应用价值。     

Why male adolescent bicyclists perform risky stunts? A qualitative study

Stunts are one of the main reasons for traffic accidents, particularly among male adolescent bicyclists (ABs). Nonetheless, there are limited data about the theoretical framework of its contributing factors. Moreover, the theoretical frameworks explaining the factors contributing to other risky behaviors have not been used in the area of risky bicycle stunts. The aim of this qualitative study was to explore the factors contributing to risky stunts among male ABs in Iran. This qualitative study was conducted from September 2019 to December 2020 using conventional content analysis. Participants were 29 male ABs purposively selected from Isfahan, Iran. Data were collected through eighteen interviews with sixteen ABs and three focus group discussions with thirteen ABs. Data analysis was conducted concurrently with data collection through conventional qualitative content analysis. The mean of participants’ age was 16.4 ± 1.1 years. Factors contributing to their engagement in risky stunts were grouped into three main themes, namely predisposing personal factors (such as risk underestimation, perceived superiority, sensation seeking, emotional condition, and previous stunt-related experiences), reinforcing social factors (such as supportive social norms and weaknesses of traffic regulations), and environmental conditions (such as time conditions and structural factors). This study provides a new classification of the facilitators to risky stunts among male ABs and reveals new facilitators to these stunts, namely perceived superiority and police non-deterrent reactions to stunts. Therefore, programs on the improvement of safe bicycling should focus not only on perceptual and emotional factors and correction of false perceived superiority through education, but also on social norms and beliefs, regulations, and environmental factors.

教师教学自主权与教师领导力的关系：心理授权和教学自主性的中介作用

教师领导力是指教师在课堂内外带领同事提升专业技能,与其他教师和校长合作处理学校事务的一种专业特质。为探究教师教学自主权与教师领导力的关系,以及教师心理授权和教学自主性的中介作用,从而寻求提升教师领导力的路径,研究选取403名中小学教师进行问卷调查。结果发现：（1）教学自主权与教师领导力呈显著正相关,且前者对后者有显著直接效应;（2）教师心理授权和教学自主性分别在教学自主权与教师领导力间发挥部分中介作用;（3）教师心理授权和教学自主性在教学自主权对教师领导力间发挥部分链式中介作用,即教学自主权的提高会促进教师心理授权和教学自主性的提升,进而促进教师领导力的发展。     

Preterm infants’ orally directed behaviors and behavioral state responses to the integrated H-HOPE intervention

Preterm infants are challenged by immature infant behavioral organization which may negatively influence their ability to oral feed. The purpose of this study was to determine whether the integrated H-HOPE (Hospital to Home: Optimizing the Infant's Environment) intervention would improve infant behavioral organization by increasing the frequency of orally directed behaviors and the proportion of time spent in an alert behavioral state when offered prior to oral feeding. Mother–infant dyads (n = 198) were randomly assigned to the H-HOPE intervention or the Attention Control groups. Infants were born at 29–34 weeks gestation and were clinically stable. Mothers had at least two social environmental risk factors such as minority status or less than high school education. H-HOPE is an integrated intervention that included (1) twice-daily infant directed stimulation using the ATVV intervention (auditory, tactile, visual, and vestibular stimuli) and (2) maternal participatory guidance sessions by a nurse-community advocate team. Orally directed behaviors and behavioral states were assessed weekly prior to feeding during hospitalization when infants were able to feed orally. There were no differences between the groups at baseline (Day 0, prior to the initiation of the integrated H-HOPE intervention). We observed a pattern of increased frequency of orally directed behaviors in the H-HOPE intervention group when compared to the Attention Control group, however, the proportion of time spent in an alert behavioral state remained stable in both groups over the course of the study. On Day 7, the H-HOPE intervention group exhibited a significantly higher mean frequency of orally directed behaviors than the Attention Control group (12.6 vs. 7.1 pre-intervention, 51.8 vs. 33.2 during intervention, 4.3 vs. 3.2 immediately after intervention, and 8.9 vs. 5.3 immediately prior to feeding). On Day 7, the H-HOPE intervention group exhibited a significantly higher proportion of time spent in an alert behavioral state only during intervention (0.26 vs. 0.11) and immediately after intervention (0.28 vs. 0.06). These findings are suggestive that the integrated H-HOPE intervention facilitated infant behavioral organization for clinically stable infants born between 29 and 34 weeks gestation. The orally directed behaviors appear to be an important indicator of the infant's preparation for feeding, and when used in conjunction with assessment of behavioral states, are especially valuable to the clinician. Use of this combined assessment approach in practice would strengthen clinician assessment for initiation of (beginning the first oral feeding) and daily preparation for oral feeding in preterm infants.     

Manager–salesperson congruence in customer orientation and job outcomes: The bright and dark sides of leadership in aligning values

To create customer-oriented organizations, managers are often asked to promote a values-based vision. Yet, many managers struggle with transferring their values to employees making strategic value changes difficult. Despite this challenge, research has yet to demonstrate how managers effectively align values within the sales force, or the impact alignment has on job outcomes. Therefore, we develop and empirically test a conceptual framework to examine the role of transformational leadership in aligning salesperson customer orientation (CO) values. We find that transformational leadership is a strong mechanism in creating perceived value congruence, yet may have a surprising dark side. Results suggest that transformational managers achieve congruence by raising or, contrary to conventional wisdom, lowering salesperson CO values to meet the perceived values of the manager. Response surface modelling results support the importance of perceived manager values. Customer-oriented salespeople have higher job satisfaction and sales performance when they perceive their manager to also have high CO. When values are misaligned, job satisfaction increases more for low CO salespeople as perceptions of manager CO increase. Exploratory findings show that performance was higher under situations of perfect alignment but also under severe misalignment suggesting that values generate performance under complementary or supplementary conditions.     

Seeing the unseen: ostracism interventionary behaviour and its impact on employees

This article outlines the development and validation of the ostracism interventionary behaviour (OIB) scale. Based on in-depth interviews with employees, leaders, and content experts in addition to 603 survey respondents from Canada and the United States, 3 dimensions emerged to describe the ways in which leaders confront workplace ostracism-related cues and a measure was created to assess them. These refer to the ability for leaders to foster an inclusive workgroup dynamic and enact effective third-party interpersonal interventions through displays of (1) social awareness, (2) proactivity, and (3) harmony-seeking behaviour. In addition to possessing convergent and discriminant validity, the OIB scale demonstrated criterion-related validity through its relation with perceived workplace ostracism and well-being. Furthermore, evidence supported the scale’s test–retest reliability and predictive validity over and above leader–member exchange. Overall, the measure was found to be both reliable and valid, with important implications for the effective management of instances of ostracism at work.     

Eating behaviors and emotional distress are predicted by treatment and adverse outcome in patients with type 2 diabetes

Depression and anxiety are hightly prevalent among patients with Type 2 Diabetes (T2D), however not commonly related to outcomes, treatment and comorbidities. Eating behaviors could also have an implication. To evaluate the relation between mood and eating behaviors with demographic, physical, treatment, biochemical profiles and chronic comorbidities in T2D we conducted this exploratory cross sectional study in a population from Mexico. Hospital Anxiety and Depression Scale and the Three Factor Eating Questionnaire Revised 21 (TFEQ-R21) were correlated with age, gender, blood pressure, treatment and comorbidities (nephropathy, neuropathy, retinopathy and cardiopathy). Multi-linear regression models and 2^k factorial analyses were conducted. Sixty-one patients (31 male) 55 years old (SD 13) with at least 5 years of T2D were included. Anxiety correlated with depression (r = 0.25, p < 0.05). Gender (women) (std B 0.026, p < 0.001), insulin therapy (std B 0.3, p = 0.11), systolic blood pressure (std B 0.263, p = 0.02) and cardiovascular disease (std B 0.232, p = 0.035) predicted depression. Insulin therapy had a positive effect in cognitive restraint. (std B 0.32, p = 0.001). Age (std B 0.37, p = 0.003) and systolic blood pressure (std B 0.237, p = 0.048) predicted positively emotional eating (not previously published). 2^k factorial analyses proved additive interaction between complications and insulin therapy with depression. This study supports the relation between mood disorders and eating behaviors with demographic, physical, treatment, biochemical profiles and chronic comorbidities in T2D and the additive interaction between factors and mood disorders.     

Effects of Share the Keys (STK), a comprehensive,behavioral-based training program for parents and new teen drivers in New Jersey

The New Jersey Graduated Driver License (GDL) restrictions were updated in 2010 with changes that included a more active role of parents monitoring practice driving with their teens. In addition to extending the driving phases, there were new curfew and passenger limit restrictions. Teen drivers were also required to use red decals on license plates to identify themselves as inexperienced drivers. The Division of Highway Traffic Safety had partnered with the Motor Vehicle Commission in the past to produce practice driving guides for parents of teen drivers, but recognized the need to support this type of informational campaign with an educational program for helping parents to understand changes in the GDL and recognize the importance of their role in the GDL monitoring process. In 2010, the New Jersey Parent/Teen Driver Orientation program was developed to educate parents of teen drivers on the new GDL restrictions and Children’s Hospital of Philadelphia (CHOP) findings concerning the importance of parenting roles in teen driver safety. Additional resources were incorporated into the orientation that included the Centers for Disease Control (CDC) community based information and the University of Michigan Transportation Research Institute (UMTRI) parent-teen driver contracts.This community-based training, known as the New Jersey Parent/Teen Driver Orientation was later renamed Share the Keys, and had been developed for the state as a component of the New Jersey Highway Safety grant received by Kean University. The comprehensive program was designed to engage parents, teens, educators, and law enforcement in the teen driving process and help parents to understand how personal parenting styles and engagement may impact teen crash risk and compliance with the GDL restrictions. Local representatives from traffic safety and law enforcement teamed with school officials and driver education teachers to present programs in their communities. The evaluation process was built into the program as a pre-survey administered at the beginning of the session, a post-survey completed directly afterward, and a voluntary follow-up survey completed on line or mailed, beginning six months later.Evidence from the first year showed that parents maintained a significant level of engagement throughout the GDL process with their teen drivers. However, findings did establish the need to further examine why Authoritative parenting styles had declined, especially since this parenting approach was considered in the literature as most effective in reducing teen crash risks. Therefore, the scope of this study was broadened to a three year effort that reached over 2800 parents and investigated behavioral outcomes impacted by Share the Keys. While comparisons made between driving phases and parenting styles had yielded no significant results, changes within parenting style scores were shown to be effective over time. The reported levels of Permissive and Uninvolved parents remained consistent throughout all three driving phases, while Authoritarian parenting peaked during the Probationary phase, and Authoritative parenting was noted as highest once teens earned their license.     

Le rôle des stresseurs sur le comportement d’innovation : Quand le leadership habilitant du supérieur protège le potentiel d’innovation des travailleurs

This study focuses on the relationship between workplace stressors and innovative work behavior. The joint analysis of the mediation process supporting this relationship as well as the influence of certain external conditions such as the moderating role of the supervisor has made it possible to highlight the dynamic that underlie the relationship between stressors and innovation behavior. Using the challenge-hindrance model, this theory proposes that challenge (i.e., role overload) and hindrance (i.e., role ambiguity and role conflict) stressors exert positive and negative indirect effects, respectively, on innovative work behavior through psychological empowerment (PE). Furthermore, empowering leadership (EL) has the potential to optimize the benefits of challenge stressors and reduce the effects of hindrance stressors on PE and indirectly on innovation work behavior. In support of these predictions, a time-lagged study of 146 employees from various Canadian firms reveals that hindrance stressors, particularly role ambiguity, are negatively related to innovative work behavior through PE. Moreover, when EL was high, the positive effects of role overload were enhanced through PE while the negative effects of role ambiguity and role conflict were attenuated. The implications of these findings for research and practice are discussed.
