Recidivism treatment manuals: a corpus-based examination for public offender counselors

Introduction This study explored two widely used recidivism-prevention manuals: the Cognitive Behavioral Interventions–Core Adult (CBI-CA) and Thinking for a Change (T4C). The aim was to identify key linguistic patterns, including keyness (word-usage differences) and collocation (word-usage associations), that may influence treatment efficacy and cultural responsiveness in offender counseling. Measures and methods Keyness analysis, performed via the log-likelihood ratio test (G2), revealed statistically significant lexical differences. Collocation analysis via Mutual Information (MI) highlighted important word-usage associations. Results The findings indicated that the CBI-CA manual emphasized motivational and psychoeducational language (e.g., “module,” “success,” and “worksheet”), whereas the T4C manual displayed a more institutional focus (e.g., “lesson,” “supplement,” and “handout”). Collocation analysis further revealed distinct framing of criminogenic factors, with CBI-CA underscoring mental health and personal growth and T4C centering on systemic and justice-related constructs. Discussion These findings highlight the need for culturally attuned and linguistically sensitive approaches in evidence-based recidivism treatment. Implications include refining curriculum design to enhance both therapeutic efficacy and inclusivity. Future research should explore the cross-cultural adaptability of treatment manuals to address systemic inequities in offender rehabilitation.
