嵌入于社会情境的工作重塑

工作重塑实质上是一种情境性的主动性行为。基于已有研究成果,首先系统归纳工作重塑与社会情境因素之间关系的4种研究视角,即社会情境是工作重塑的目标、社会情境因素是工作重塑的组成部分、社会情境因素影响工作重塑、社会情境因素为工作重塑设立边界条件。此外,梳理并讨论社会情境因素影响工作重塑的内在机制以及社会情境因素与个体特征的交互对于工作重塑的影响、工作重塑在特定情境中的有效性两方面的研究。在此基础上,结合其他相关变量的研究现状对嵌入于社会情境的工作重塑的未来研究进行展望,包括探索工作重塑对他人的影响、探索团队工作重塑驱动个体工作重塑的多重路径、探索社会情境影响工作重塑的内在机制、探索社会情境与个体特征的交互如何影响工作重塑,以及探讨基于中国社会情境的工作重塑的有效性。     

Problems with Rationales for Parceling that Fail to Consider Parcel-Allocation Variability

In structural equation modeling applications, parcels—averages or sums of subsets of item scores—are often used as indicators of latent constructs. Parcel-allocation variability (PAV) is variability in results that arises within sample across alternative item-to-parcel allocations. PAV can manifest in all results of a parcel-level model (e.g., model fit, parameter estimates, standard errors, and inferential decisions). It is a source of uncertainty in parcel-level model results that can be investigated, reported, and accounted for. Failing to do so raises representativeness and replicability concerns. However, in recent methodological literature (Cole, Perkins, &; Zelkowitz, 2016 Cole, D. A., Perkins, C. E., &; Zelkowitz, R. L. (2016). Impact of homogeneous and heterogeneous parceling strategies when latent variables represent multidimensional constructs.

Psychological Methods, 21(3), 348–368. doi: 10.1037/met0000072[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) parceling has been justified and recommended in several situations without quantifying or accounting for PAV. In this article, we explain and demonstrate problems with these rationales. Overall, we find that: (1) using a purposive parceling algorithm for a multidimensional construct does not avoid PAV; (2) passing a test of unidimensionality of the item-level model need not avoid PAV; and (3) a desire to improve power for detecting structural misspecification does not warrant parceling without addressing PAV; we show how to simultaneously avoid PAV and obtain even higher power by comparing item-level models differing in structural constraints. Implications for practice are discussed.     

Does Reintegration Stress Contribute to Suicidal Ideation Among Returning Veterans Seeking PTSD Treatment?

Although posttraumatic stress disorder (PTSD) and other psychiatric symptoms are well‐established risk factors for suicidal ideation among returning veterans, less attention has been paid to whether the stress of reintegrating into civilian society contributes to suicidal ideation. Utilizing a sample of 232 returning veterans (95% male, mean age = 33.63 years) seeking PTSD treatment, this study tested whether reintegration difficulties contribute to suicidal ideation over and above the influence of PTSD symptoms, depression symptoms, and potential substance misuse. Logistic regressions indicated that reintegration stress had a unique effect on suicidal ideation over and above PTSD and depression symptoms. Reintegration stress interacted with substance misuse to predict suicidal ideation, such that the effect of reintegration stress on suicidal ideation was much larger for those with potential substance misuse. Exploratory analyses also examined which types of reintegration difficulties were associated with suicidal ideation, and found that difficulty maintaining military friendships, difficulty getting along with relatives, difficulty feeling like you belong in civilian society, and difficulty finding meaning/purpose in life were all significantly associated with suicidal ideation, beyond the effects of psychiatric symptoms and potential substance misuse. Findings highlight the importance of addressing reintegration stress for the prevention of suicide among returning veterans. Implications for treatment are discussed.
