This study examines treatment typologies over time and their relationship to reoffending outcomes. Latent transition analysis was conducted with 6,675 men on community supervision in Alberta, Canada using risk and strength factors measured by the Service Planning Instrument (Orbis Partners, 2003). Three timepoints were assessed: Time 1 = first assessment within 90 days of start of supervision, Time 2 = 3 to 8 months post initial assessment, and Time 3 = 9 to 14 months post initial assessment. Five profiles consistently emerged: Low risk/Low strength profile, Aggressive, complex need/Low strength profile, Moderate risk/Moderate strength profile, Low risk/High strength profile, and Non-aggressive, complex need/Low strength profile. At Time 3, a sixth profile emerged labeled Moderate complex need/Low strength. Profiles characterized as aggressive and those with complex needs had highest rates of reoffending. Results demonstrate the utility of incorporating strengths, mental health needs, and adverse childhood experiences in risk assessment protocols.
