The identity constructs studied fall into social, developmental, and motivational types.

Evidence

Following Vignoles and colleagues’ suggestion, we categorized the identity concepts into (1) social and contextual perspectives on identity, (2) personal and developmental perspectives on identity, and (3) the needs and motives underlying identity processes. In the following sections, we present the various conceptualizations of identity the reviewed studies employed, how the con­ cepts were operationalized, and their reported relation with violent extremism. — Lea Echelmeyer, Anne-Marie Slotboom, and Frank Weerman, The Putative Effect of Identity on…, 193

Categorization

• DEFINE: Establishes the three-way taxonomy used to sort every identity concept in the review, which is the backbone of any construct-alignment assessment.
• XREF: Connects directly to the negative-identity/negative-antihero mechanism, which sits in the personal-developmental bucket rather than the social one.
