Associated data for Systematic Scoping Review - Identity in human behaviour change and maintenance

Many theories of motivation recognize a person’s identity adds value to the prediction of behavior; albeit indirectly, through constructs such as social norms, self-efficacy, perceived behavioral control, and values. Recently, behavioral research has more directly assessed the influence of identity on behavior; however, it is unclear whether such research aligns with the theoretical establishments of identity. This review investigated the identity theory alignment of existing behavior research by systematically searching, screening, and reviewing identity-behavior relevant papers, across three behavioral psychology databases. Twenty-three papers meet the inclusion criteria for review (original research with a primary focus on identity and behavior, within healthy adult population), and data relating to identity-behavior theoretical viewpoints, research methods, and study findings were extracted and synthesized to provide a scoping overview of current research. Most reviewed papers presented identity as a loosely defined construct; commonly operationalized as social identity, omitting the theorized multiplicity of social and self-identities. Overall outcomes suggested that identity influences behavior indirectly through intention strength, rather than directly as a post-intention mechanism. While existing research has been crucial in illuminating potential influences of identity on behavior, there is a need to strengthen current understandings and theoretical alignments within future research relating to identity and behavior.

许多动机理论认为，个体的身份认同（identity）可提升行为预测的价值——尽管这种影响是间接的，需通过社会规范、自我效能感、感知行为控制及价值观等构念（constructs）实现。近年来，行为研究更直接地评估了身份认同对行为的影响；然而，此类研究是否与身份认同的理论基础相一致尚不明确。本综述通过对三个行为心理学数据库中与身份-行为相关的论文进行系统检索、筛选与综述，探讨了现有行为研究与身份理论的契合度。23篇论文符合纳入标准（以身份认同与行为为核心焦点的原创研究，研究对象为健康成年人群体），研究提取并综合了与身份-行为理论视角、研究方法及研究结果相关的数据，以呈现当前研究的范围概览。多数被综述的论文将身份认同视为定义松散的构念；其操作化常局限于社会身份认同，却忽略了理论中社会身份与自我身份的多元性。总体结果表明，身份认同通过意图强度间接影响行为，而非作为意图形成后的机制直接作用于行为。尽管现有研究对阐明身份认同对行为的潜在影响至关重要，但未来关于身份认同与行为的研究仍需强化当前的认知深度与理论契合性。
