近几十年来，积极心理学的研究蓬勃兴起，其中典型代表主观幸福感作为与人们生活与健康息息相关的概念亦不断得到阐释与发展。而在千百年前佛学领域便早已涉足对于幸福的探讨，例如佛学中的正念、冥想等均为人们获得幸福的妙法，并且在当代心理学框架下得到了证实。然而博大精深的佛学智慧在此之外想必依然会有更多提升幸福的因素，譬如佛学布施（Buddhism Generosity）。前人研究发现虽然作为黑暗人格化身的人格黑三角对主观幸福感起反向预测作用，而布施可能也对主观幸福感起预测作用，但三者的作用机制还需要进一步探讨。布施作为佛学六度理论之首，是个体修行自身并逐渐走向慈悲、同情、自利利他以及最终修炼成为菩萨的第一步，是一种在人际互动中保持积极和善、帮扶他人的适应性的应对方式。为探索三者的内在联系，本研究利用三个子研究，结合问卷法和实验法考察了布施在人格黑三角和主观幸福感之间潜在的中介作用，并考察人格黑三角与布施、布施与主观幸福感之间两两潜在的因果关系。其中研究I使用问卷法调查北京地区252名高校学生，考察人格黑三角、布施与主观幸福感之间的相关关系和布施的中介作用，结果发现：（1）人格黑三角与布施显著负相关；（2）人格黑三角和主观幸福感显著负相关；（3）布施与主观幸福感显著正相关；（4）布施部分中介人格黑三角与主观幸福感间的关系。同时在研究I的基础上，研究II以北京地区91名高校学生、研究III以北京地区137名高校学生为被试，通过启动实验分别探索人格黑三角与布施、布施与主观幸福感之间的因果关系。结果表明，人格黑三角负向预测布施；布施正向预测主观幸福感。综合上述三个子研究的结果可知，人格黑三角不仅直接影响布施，还通过影响布施来间接影响主观幸福感。研究在一定程度上揭示了三者的作用机制，也为如何提升幸福感提供了新的路径。

In recent decades, the study of positive psychology has flourished, and the typical representative of subjective well-being as a concept closely related to people's life and health has been continuously explained and developed. In the field of Buddhism thousands of years ago, it has already been involved in the discussion of happiness. For example, mindfulness and meditation in Buddhism are all wonderful ways for people to get happiness, and they have been confirmed in the framework of contemporary psychology. However, there must be more factors to enhance happiness in the profound Buddhist wisdom. Previous studies have found that although the Dark-Triad as the incarnation of dark personality has a reverse predictive effect on subjective well-being, and Buddhism Generosity may also predict the subjective well-being, the mechanism of action of the three needs further exploration. As the first of the six perfections of Buddhism, Buddhism Generosity is the first step for the individual to practice himself and gradually move toward compassion, sympathy, self-interest, and eventually cultivation into a bodhisattva. It is a kind of adaptability to maintain positive and good and help others in interpersonal interaction. In order to explore the internal relationship among the three variables, this study used three sub-studies, combined with questionnaires and experimental methods to examine the potential mediating role of Buddhism Generosity in the Dark-Triad of personality and subjective well-being, and to examine the potential causal relationships between Dark-Triad of personality and Buddhism Generosity, and between Buddhism Generosity and subjective. Among them, Study I used questionnaires to investigate 252 college students in Beijing, and examined the correlation between Dark-Triad, Buddhism Generosity and subjective well-being and the mediating role of Buddhism Generosity. The results showed that: (1) Dark-Triad was significantly negatively correlated with Buddhism Generosity; (2) There is a significant negative correlation between Dark-Triad and subjective well-being; (3) a significant positive correlation between Buddhism Generosity and subjective well-being; (4) the mediating effect of Buddhism Generosity between the Dark-Triad and subjective well-being. At the same time, on the basis of the research I, the research II is based on 91 college students in Beijing, and the research III is 137 college students in Beijing. The experiment is to explore the causal relationship between the Dark-Triad of personality and the Buddhism Generosity, Buddhism Generosity and subjective well-being. The results showed that the negative Dark-Triad predicts Buddhism Generosity, and the Buddhism Generosity is positively predicting subjective well-being. Based on the results of the above three sub-studies, it is known that the Dark-Triad not only directly affects the Buddhism Generosity, but also indirectly affects subjective well-being by influencing the Buddhism Generosity. The research reveals to some extent the mechanism of action of the three, and also provides a new path for how to improve happiness.
