Behaviour Modification
The Cognitive-Behavioural Model of Anger
Novaco (1975) proposed that anger is not simply an automatic response to provocation but is mediated by cognitive appraisal. Events are interpreted as threatening, insulting, or unjust; this appraisal generates physiological arousal; arousal in turn produces aggressive behaviour. This cognitive-behavioural model identifies three components of the anger–aggression cycle: cognition (hostile interpretation), affect (physiological arousal), and behaviour (aggression). The implication is that interventions can target any or all three components.
The Three-Stage Anger Management Programme
Anger management programmes used in custodial and forensic settings are based on Stress Inoculation Training (Meichenbaum, 1977) adapted to anger. They proceed through three stages:
Stage 1: Cognitive Preparation
The offender works with a therapist to identify personal anger triggers — the specific situations, people, and thoughts that provoke anger. They learn to recognise the hostile attribution bias — the tendency to interpret ambiguous actions by others as deliberate and threatening — and begin the process of cognitive restructuring: replacing automatic hostile appraisals with more neutral or benign interpretations. The rationale for treatment is explained using the inoculation metaphor (exposure to a weakened version of the stressor to build resilience).
Stage 2: Skills Acquisition
Practical techniques are taught to interrupt the anger cycle before aggressive behaviour occurs. These include: relaxation skills (deep breathing, progressive muscle relaxation) to reduce physiological arousal; cognitive restructuring strategies to challenge and replace hostile thoughts in the moment; and assertiveness training to express frustration and disagreement without aggression.
Stage 3: Application Practice
Skills are rehearsed through role-play and behavioural rehearsal, with the therapist introducing increasingly provocative scenarios in a controlled setting. This graduated exposure allows the offender to practise applying cognitive and relaxation skills under conditions that simulate real-life triggers, building confidence and automaticity before the skills are needed outside the therapeutic context.
Research Evidence
Novaco (1975) demonstrated that a cognitive-behavioural anger management programme produced significant reductions in both subjective anger and physiological arousal measures compared to a control group receiving only relaxation training — supporting the importance of the cognitive component.
Ireland (2004) evaluated anger management with 50 young male offenders completing an 8-week programme compared to 37 controls. She found that 92% of programme completers showed improvement on at least one measure of anger or aggressive behaviour, with significant reductions in problem behaviour compared to controls.
Howells et al. (2005) highlighted the importance of 'anger readiness': participants who were not genuinely motivated to change showed little or no benefit from anger management. Offenders who denied having an anger problem, or who were mandated to attend without intrinsic motivation, gained minimal therapeutic benefit.
Evaluation
Anger management is more comprehensive than token economy: it directly targets the cognitive distortions (hostile attribution bias) and physiological arousal underlying violent offending, rather than merely modifying surface behaviour through external reinforcement. Ireland's (2004) study is frequently cited as evidence of effectiveness, though it has limitations: no random assignment to conditions (the treatment group self-selected by completing the programme), self-report measures of anger are susceptible to demand characteristics, and the short follow-up period does not assess long-term recidivism. Howells et al. (2005) raise the important question of motivation: anger management requires genuine engagement and the capacity for self-reflection, which not all prisoners possess or are willing to demonstrate.
Key Takeaways
- Novaco (1975): anger = cognitive appraisal → arousal → aggression. CBT intervention targets all three components.
- Three stages: (1) Cognitive preparation — identify triggers, restructure hostile appraisals; (2) Skills acquisition — relaxation, assertiveness; (3) Application practice — role-play and graduated exposure.
- Novaco (1975): CBT anger management → ↓anger and physiological arousal vs relaxation-only control.
- Ireland (2004): 50 young offenders vs 37 controls; 92% of completers improved on ≥1 measure; significant reductions in aggression.
- Howells et al. (2005): anger readiness essential — unmotivated offenders gain little benefit.
- Limitations: Ireland (2004) — no random assignment, self-report; requires motivation and insight; may not generalise post-release.
