结构方程模型的应用及分析策略 总被引:24,自引:0,他引:24
差不多所有心理、教育、社会等概念,均难以直接准确测量,结构方程(SEM,Struc-tulalEquationModelling)提供一个处理测量误差的方法,采用多个指标去反映潜在变量,也令估计整个模型因子间关系,较传统回归方法更为准确合理。本文主要用一系列有关学习动机的虚拟例子,指出每个问题的主要分析策略,以展示SEM在教育及心理学可以应用的研究范畴。文内探讨的方法包括:验证性因素、高阶因子、路径及因果分析、多时段(multiwave)设计、单形模型(SimpleModel)、及多组比较等。 相似文献

Just as chemistry has methods for determining the composition of unknown substances, psychology needs, but has lacked, effective methods for identifying the "active ingredients" of social stimuli. We describe such a method and apply it to identify the verbal and nonverbal distress cues that serve as signals prompting others to provide social support. This method allowed us to identify 55 such cues. Furthermore, the cues that were salient in the minds of potential support providers depended on their goals. For example, when deciding whether someone needed support, negative nonverbal cues (e.g., distressed persons' fidgeting) were more salient, but when deciding whether one was willing to provide support, cues that suggested a positive outcome for the support seeker (e.g., distressed persons' positive attitude and open-mindedness) were more salient. 相似文献

This research identifies four challenges in the field of person–environment fit (PE fit): the multidimensionality of PE fit, the integration of fit theories, the simultaneous effects of the multiple dimensions, and the function of the dimensions. To address those challenges, we develop a theory‐driven and systematically validated multidimensional instrument, the Perceived Person–Environment Fit Scale (PPEFS), consisting of four measures: the Person–Job Fit Scale (PJFS), the Person–Organisation Fit Scale (POFS), the Person–Group Fit Scale (PGFS), and the Person–Supervisor Fit Scale (PSFS). Data are collected from 532 employees and 122 managers for two independent studies with multiple rater sources and multiple time points. A series of validation analyses and hypothesis tests reveals that the PPEFS measures have good psychometric properties (i.e. reliability, convergent validity, discriminant validity, and criterion‐related validity) and exhibit incremental validity above and beyond Cable and DeRue's (2002) fit measures. Furthermore, the measures are reflected by a superordinate (vs. aggregate) construct of PE fit. Overall, the four different types of fit significantly predict in‐role behavior, job satisfaction, intent to quit, and organisational citizenship behavior (OCB), each explaining the greatest amount of variance in different outcomes. The PPEFS should prove useful in future research regarding PE fit. 相似文献

This paper describes a program of brief, universal, positive psychology-based interventions to increase targeted behaviors that enhance family relationships, developed and delivered to over 1500 participants using a community-based participatory approach. The cluster-randomized design combined interventions based on one of three themes (gratitude, hope, or open-mindedness) in one of two structures (intervention, or intervention with planning). The latter structure supplemented with materials and exercises derived from the Health Action Process Approach model of behavior change. Planning was more effective in increasing attitude and intention to perform behaviors, frequency of the targeted behaviors, and family health and happiness (Cohen’s ds: 0.10–0.16, p < 0.05), particularly in the theme targeting open-mindedness. Qualitative data supported effectiveness. This project was a first effort to develop a large-scale preventive psychological intervention in an understudied culture with the goal of maximizing acceptability and utilization by involving community stakeholders in every stage of the design. 相似文献

There is ample evidence in the relevant literature to show that self‐identity threat affects consumers' behavior, psychological needs, purchasing behavior, and product choice. The present research takes self‐identity threat to another level with a focus on the moderating role of power distance belief (PDB) in the relation to self‐identity threat and status consumption. The research involves two studies. Study 1 shows that threatened participants with a high PDB prefer status goods to nonstatus goods. By contrast, the low‐PDB group is indifferent to the status of goods. Study 2 reexamines the results of Study 2 with different participants and goods and tests the moderated mediation of symbolic compensatory need in the status consumption of high‐PDB participants. The results and implications of our findings are presented in the Discussion section. 相似文献

This empirical study investigated the relationship between racial identity and attitudes toward people with disabilities. Results indicate that higher statuses of racial identity correlate positively while lower and more racist‐oriented statuses correlate negatively with attitudes toward people with disabilities. The study supports the notion that attitudes from cultural memberships associated with power can transfer from one domain (i.e., White/People of Color) to another domain (i.e., Abled/Disabled). Este estudio empírico investigó la relación entre la identidad y actitudes raciales hacia personas con incapacidades. Los resultados indican que las posiciones más altas de la identidad racial se pone en correlación positivamente mientras bajan y más posiciones racista‐orientados se pone en correlación negativamente con actitudes hacia personas con incapacidades. El estudio sostiene la noción que actitudes de asociaciones culturales asociadas con el poder pueden transferir de un dominio (es decir, los Blancos/Personas del Color) a otro dominio (es decir, Capacitados/Incapacitados). 相似文献

With concussion rates on the rise for football players, there is a need for further research to increase skills and decrease injuries. Behavioral skills training is effective in teaching a wide variety of skills but has yet to be studied in the sports setting. We evaluated behavioral skills training to teach safer tackling techniques to six participants from a Pop Warner football team. Safer tackling techniques increased during practice and generalized to games for the two participants who had opportunities to tackle in games. 相似文献

Integrated Primary Care: An Inclusive Three-World View Through Process Metrics and Empirical Discrimination 总被引:1,自引:1,他引:0

Integrating behavioral health services within the primary care setting drives higher levels of collaborative care, and is
proving to be an essential part of the solution for our struggling American healthcare system. However, justification for
implementing and sustaining integrated and collaborative care has shown to be a formidable task. In an attempt to move beyond
conflicting terminology found in the literature, we delineate terms and suggest a standardized nomenclature. Further, we maintain
that addressing the three principal worlds of healthcare (clinical, operational, financial) is requisite in making sense of
the spectrum of available implementations and ultimately transitioning collaborative care into the mainstream. Using a model
that deconstructs process metrics into factors/barriers and generalizes behavioral health provider roles into major categories
provides a framework to empirically discriminate between implementations across specific settings. This approach offers practical
guidelines for care sites implementing integrated and collaborative care and defines a research framework to produce the evidence
required for the aforementioned clinical, operational and financial worlds of this important movement. 相似文献
