A Situational-Structural Integrative Model of Illicit Identity Formation

Thesis Abstract

The study investigates how situational and structural mechanisms interact to shape illicit identity formation among youth exposed to high-risk environments, addressing gaps in criminological theories that treat criminal identity as either purely individual or purely contextual. The aim is to develop and validate a Situational-Structural Integrative Model (SSIM) that explicates how proximal situational cues, perceived social legitimacy, opportunity structures, and structural marginalization co-construct an individual's propensity to internalize an illicit identity. Specific objectives are to (1) identify salient situational triggers (observed peer engagement, anonymity, perceived risk) and structural determinants (economic deprivation, policing exposure, community collective efficacy) associated with illicit self-concept; (2) examine the mediating role of perceived legitimacy of illicit activity and self-efficacy beliefs in the transition from role exposure to identity integration; (3) test the predictive validity of SSIM against alternative models incorporating only situational or only structural factors; and (4) derive policy-relevant implications for diversion, policing, and rehabilitative interventions. The study employs a mixed-methods design. A cross-sectional survey will be administered to 1,200 individuals aged 16 to 25 across five urban neighborhoods with varying crime prevalence, using stratified random sampling to ensure representation by gender, ethnicity, and socioeconomic status. Instrumentation includes a structured questionnaire capturing illicit identity indicators (validated Illicit Identity Scale), situational exposure indexes (peer network risk, routine activity measures), and structural context measures (neighborhood disorder, unemployment rates, police contact). The instrument set will be complemented by semi-structured interviews with a purposive subsample of 60 participants to explore subjective meaning-making processes and to identify latent constructs not captured by quantitative measures. Data collection will occur over nine months, with ethical approvals obtained from an institutional review board and informed consent procedures tailored for minor participants where applicable. Quantitative analysis will proceed in three stages. First, exploratory and confirmatory factor analyses will validate the measurement model for the latent constructs in SSIM. Second, structural equation modeling (SEM) will assess direct, indirect, and total effects among situational cues, structural determinants, perceived legitimacy, self-efficacy, and illicit identity outcomes, testing mediation pathways posited by SSIM. Third, multi-group SEM will examine potential moderating effects by gender and ethnicity. Thematic analysis will be applied to interview transcripts, guided by Braun and Clarke’s framework, to triangulate quantitative findings and illuminate nuanced identity formation processes. Qualitative data will inform refinement of measurement items and potential contextual covariates. Expected findings include (a) significant direct effects of high-risk situational exposure and adverse structural contexts on illicit identity endorsement; (b) robust indirect effects through perceived illegitimacy of conventional norms and heightened self-efficacy within illicit activity, mediating identity formation; (c) a superior fit for SSIM relative to models that isolate situational or structural explanations, with a comparative fit index improvement of at least 0.05 and RMSEA below 0.06; and (d) evidence of moderating effects wherein gender and ethnicity alter the strength of pathways from exposure to identity internalization. The study contributes to knowledge by integrating situational and structural perspectives into a unified theory of illicit identity formation, offering a parsimonious yet comprehensive model with strong empirical support. It advances criminological theory on crime careers by operationalizing identity as a dynamic construct shaped by contextualized experiences rather than static dispositions. Methodologically, it demonstrates the utility of mixed methods and SEM in testing complex theories of identity formation in criminology. Policy and practice implications include targeted interventions that disrupt critical mediating pathways—such as enhancing legitimate self-efficacy, reducing perceived illegitimacy of prosocial norms, and altering perceived opportunity structures—alongside tailored policing and rehabilitative strategies that address both environmental risk factors and individual identity processes. The study concludes that illicit identity formation emerges from the cumulative interaction of situational opportunities and structural marginalization, with identity internalization most likely when individuals perceive illicit activity as socially sanctioned within their local milieu and possess confidence in illicit capabilities, underscoring the need for holistic, context-sensitive prevention and reform programs.
