生命意义是指人们如何理解他们的生活，如何确定和追求目标，发现他们的生活有连 贯性、目的性和重要性，它包括存在意义和寻求意义两个维度。大五人格是应用最广泛的 人格特质模型，用于评估个体在心理、行为和情感方面相对稳定的差异。国内外大量关于 大五人格特质与生命意义相关关系的研究结果存在较大分歧，且尚未有研究对大五人格特 质与生命意义关系进行系统梳理归纳，或从宏观上剖析研究结果不一致的原因。本研究采 用元分析方法来探讨大五人格特质与生命意义的相关关系，重点关注了霍夫斯塔德国家文 化六个维度的调节作用。经过检索编码，本研究共纳入 66 篇文献，79 个独立样本，总样 本量为 30617 人。

元分析关于大五人格特质与生命意义相关关系的主效应结果显示，生命意义与尽责 性、外倾性呈高强度正相关（r = 0.362，r = 0.324），与宜人性、开放性呈中等强度正相关 （r = 0.253，r = 0.235），与神经质呈中等强度负相关（r = -0.271）；生命意义存在与尽责 性呈高强度正相关（r = 0.347），与宜人性、外倾性呈中等强度正相关（r = 0.227，r = 0.273）， 与开放性呈低强度正相关（r = 0.173），与神经质呈高强度负相关（r = -0.323）；生命意义 寻求与宜人性、尽责性、开放性呈低强度正相关（r = 0.11，r = 0.135，r = 0.13），与外倾 性和神经质呈极低强度正相关（r = 0.098，r = 0.014）。

元分析关于其他变量调节效应分析结果显示，年龄不存在显著调节作用，性别比、样 本群体、生命意义及大五人格测量工具都对部分相关关系存在显著调节作用。此外，个人 主义对生命意义与外倾性、生命意义与神经质，不确定性规避对生命意义与外倾性，长期 主义对生命意义寻求与尽责性均存在显著的调节作用。研究结果整合明确了大五人格特质 与生命意义的相关关系，并为生命意义理论本土化发展提出了建议与展望。

Meaning in life refers to how people make sense of their lives, identify and pursue goals, and find their lives coherent, purposeful, and significant. Meaning in life includes both presence of meaning and search for meaning dimensions. The Big Five personality theory is the most widely used model of personality traits for assessing relatively stable differences in the psychological, behavioral, and emotional aspects of individuals. A large number of domestic and international studies on the relationship between meaning in life and personality traits are highly divergent, and no studies have been conducted to systematically sort out and summarize the relationship between meaning in life and personality traits, or to dissect the reasons for inconsistent research results from a macro perspective. This study used a meta-analytic approach to explore the correlation between meaning in life and Big Five personality traits, focusing on the moderating role of the six dimensions of Hofstede's national culture. A total of 66 empirical studies with a total sample size of 30,617 individuals were obtained through a literature search included in the coding. Meta-analysis results showed that meaning in life was high strength positively correlated with conscientiousness and extroversion (r = 0.362, r = 0.324), moderately strongly positively correlated with agreeableness and openness (r = 0.253, r = 0.235), and moderately strongly negatively correlated with neuroticism (r = -0.271); presence of meaning was high intensity positive correlation with conscientiousness (r = 0.347), moderately strongly positively correlated with agreeableness and extroversion (r = 0.227, r = 0.273), low intensity positive correlation with openness (r = 0.173), and high intensity negative correlation with neuroticism (r = -0.323); search for meaning had low intensity positive correlations with agreeableness, conscientiousness, and openness (r = 0.11, r = 0.135, r = 0.13), and low intensity positive correlations with extraversion and neuroticism with very low strength positive correlations (r = 0.098, r = 0.014). The results of the moderating effect analysis showed that there was no significant moderating effect of age, while there were significant moderating effects of sex ratio, sample group, meaning in life and the Big Five personality measurement instrument on some of the correlations. In addition, there were significant moderating effects of individualism on meaning in life and extroversion, meaning in life and neuroticism, uncertainty avoidance on meaning in life and extroversion, and long-termism on search for meaning and conscientiousness. The results of the study integrate to clarify the correlation between meaning in life and Big Five personality, and make suggestions for the localization of meaning in life theory in China.
