Abstract：
Research on the extent to which people believe that people can change (incremental beliefs) suggests that incrementalist beliefs are positively related to well-being, whereas entity beliefs (people cannot change) are not. One explanation for this relationship is that incremental beliefs are associated with a mastery orientation, whereas entity beliefs are not. If this is the case, then autonomous and competence motives should mediate relationships between incrementalism and well-being because these motives reflect different aspects of mastery. The present study examined the possibility that autonomous and competence motives mediate relationships between self-theories and well-being. Participants were adult community members (n = 428) who completed the Life Engagement Test (eudaimonic well-being), the Satisfaction with life Scale (hedonic well-being), the Mental Health Continuum Scale (eudaimonic, subjective, and psychological well-being), the Basic Needs Satisfaction scale (autonomy, competence, relatedness), and a measure of implicit theories of the self (incremental and entity beliefs). Regression analyses found that incremental beliefs were significantly related (positively) to all three measures of well-being, whereas entity beliefs were not significantly related to well-being. Regression analyses also found that incremental beliefs were positively related to satisfaction of autonomy and competence needs but were not related to satisfaction of relatedness needs. Entity beliefs were not related to the satisfaction of any of the three basic needs. A series of mediational analyses found that competence and autonomy motives mediated relationships between incremental beliefs and all three measures of well-being. In all but one case, satisfaction with life, the direct effects of incremental beliefs on well-being were rendered non-significant when satisfaction of autonomy and competence needs were included as mediators. The present results confirm and extend to the general domain the supposition that a mastery orientation is responsible for relationships between well-being and incremental theories of the self. They also conform the importance of the tenants of Self-Determination Theory in understanding self-theories.
摘要：
对人们相信人们可以改变的程度（增量信念）的研究表明，增量主义信念与幸福呈正相关，而实体信仰(人不能改变)则不是。对这种关系的一种解释是，递增的信念与掌握取向有关，而实体信仰不是。如果是这样的话,那么自主和能力动机应该调解增量主义和幸福之间的关系，因为这些动机反映了掌握的不同方面。本研究考察了自主和能力动机调解自我理论与幸福感之间关系的可能性。参与者是成年社区成员（n=428），他们完成了生活参与测试（eudaimonic幸福感），生活满意度量表(享乐幸福感)，心理健康连续量表(eudaimonic，主观,和心理健康)，基本需求满意度量表(自主性，能力,相关性)，以及对自我的内隐理论(增量和实体信念)的衡量。回归分析发现，增量信念与所有三个幸福感指标显着相关（正相关），而实体信念与幸福感没有显著相关。回归分析还发现，递增的信念与自主性和能力需求的满足呈正相关，但与相关性需求的满足无关。实体信念与满足三种基本需求中的任何一种都无关。一系列中介分析发现，能力和自主性动机介导了增量信念与所有三种幸福感之间的关系。除了一种情况，对生活的满意度，当自主性和能力需求的满足被纳入调停者时,递增信念对幸福感的直接影响并不显著.本结果证实并扩展到一般领域，假设掌握取向负责幸福与自我增量理论之间的关系。它们还符合自决理论租户在理解自我理论方面的重要性。
