日记式追踪研究高校教师职业枯竭的产生原因及内部关系

该研究针对职业枯竭研究领域存在争议的两大理论问题——产生机制与内部过程,使用日记研究方法对重点高校教师进行了追踪调查。得到以下结果:1)在枯竭的成因部分:压力感、付出-回报的不平衡对耗竭存在显著正向的预测作用,且不平衡还是压力感与耗竭之间的部分中介变量。此外,二者还可完全通过耗竭作用于讥诮维度。自足资源对耗竭和讥诮均无显著影响,它只对职业效能有显著的正向预测作用,且是职业效能的唯一前因变量。2)在枯竭三维度的内部关系部分:耗竭与讥诮存在显著的正向联系,且解释风格在其中起到调节作用,即越将负性事件归因于外部环境或他人,耗竭对讥诮的正向预期作用就越强。而职业效能维度显示出与耗竭及讥诮相分离的态势,与后二者均无显著的相关关系。     

Fifth grade school adjustment and later arrest rate: A longitudinal study of middle school antisocial boys

This study investigated the efficacy of three different regression models in predicting arrest rate over the fifth to seventh grade range for a sample of antisocial and at risk control middle school boys (N=76). These boys were selected from a larger sample of approximately 200 boys and their families for inclusion in a long term longitudinal study beginning in the fourth grade. Subjects in the present study were identified when they were in the fifth grade and school measures of adjustment were recorded annually for them on two occasions (fall, spring) through the ninth grade. Predictors were derived from the following variables: (a) teacher ratings of social skills; (b) direct observations of academic engagement in classroom settings; (c) direct observations of the playground social behavior of target subjects and peers; and (d) discipline contacts with the principal's office as extracted from archival school records. These predictor variables appeared to assess respectively teacher related and peer related forms of school adjustment. The regression models investigated yielded R-Squares of approximately 30 between arrest rate and two to three predictor variables in each analysis. However, following the deletion of two subject cases that represented extreme instances of underprediction (i.e., subjects who were arrested [i.e., seven arrests each] but whose fifth grade behavioral profiles suggested they would not be), the obtained R-Squares increased to approximately .55. Implications of the findings for the early screening and identification of at risk students are discussed.     

Positive mental health,positive affect and suicide ideation

Background/ObjectivePositive mental health (PMH) has been shown to confer resilience against suicide ideation. However, the mechanisms underlying the positive effect of PMH on suicide ideation/behavior are largely unknown. The current study aimed to determine whether positive affect mediates the association between PMH and suicide ideation.MethodA total of 150 adult outpatients (65.3%; female; age: M(SD)=37.79(13.50), range:18–77) completed measures on PMH, positive and negative affect, as well as suicide ideation. Data were collected using self-report questionnaires. Linear hierarchical regression analysis was used to analyze the data. Positive affect was considered to mediate the association between positive mental health and suicide ideation.ResultsWhile positive affect fully mediated the significant negative association between PMH and suicide ideation, negative affect did not reveal to be a significant mediator of this relationship.ConclusionsThe protective influence of PMH against suicide ideation is due to heightened positive affect: If positive mental health translates into positive affect, then suicide ideation becomes less likely.     

Predictive factors of quality of life in acquired brain injury

Background/ObjectiveThe sequelae and the disability and dependence that follow an acquired brain injury (ABI) may result in a significant reduction in the quality of life (QoL) of those affected. The objective was to assess the QoL of a sample of Spanish patients with an ABI and analyze the influence of certain sociodemographic and injury-related variables on their QoL. Method: The sample comprised 421 adults (60% male; M_age = 53.12; SD = 14.87). Professionals and relatives assessed the patients’ QoL through the CAVIDACE scale, an ABI-specific tool based on the eight-domain QoL model. Results: Univariate analyses showed statistically significant differences in the QoL scores in several sociodemographic (age, civil status, education level, prior employment status, type of home, level of supports, loss of legal capacity, recognized dependence, and degree of dependence) and injury-related (time since the injury, location of the injury, and presence of post-traumatic amnesia) variables. The multiple linear regression showed that loss of legal capacity, time since the injury, prior employment status, location of the injury, and degree of dependence were significant QoL predictors. Conclusions: These findings provide knowledge for the development of programs aimed at reducing the negative impact of ABI on QoL.     

Do drivers accept cooperative behavior of their automated vehicle on highways?

Automated cooperatively interacting vehicles will change the future of traffic completely. Such vehicles will be capable of planning and carrying out maneuvers based on vehicle-to-vehicle and vehicle-to-infrastructure communication, enabling a safer driving experience. However, this gain of safety will only be effective if drivers use and accept the decisions made by advanced automated technology. Especially when drivers are cognitively distracted, new strategies might be necessary, e.g., by further explaining the reason for a cooperative decision.In a driving simulator study, we investigated the acceptance of lane change maneuvers in cooperative situations carried out by an automated vehicle on a two-lane German highway. When the automated system detected a potential lane change ahead, it carried out one of three possible maneuvers: accelerate, decelerate, or maintain speed. Participants (N = 20) were asked whether they accepted the system’s behavior either while being cognitively distracted or in an attentive state. Thus, we investigated the influence of a cognitively demanding secondary task and, in addition, further situational characteristics (Scope of action, Criticality for the lane-changing vehicle, Display of intention) on the acceptance towards the system’s behavior. Moreover, participants had to rate the perceived situation’s criticality.Results underlined the importance of explicit indication of the intention to change lanes. Furthermore, increased cognitive load led to a higher acceptance of the defensive system behavior. This study contributes to the development of a user-centered interface and interaction strategy for cooperative interacting vehicles.
