4.3.9 - Dealing with offending behaviour

Custodial Sentencing

This lesson covers the updated AQA requirement: the aims and psychological effects of custodial sentencing, behaviour modification in custody, anger management and restorative justice programmes. It is about how the criminal justice system tries to deal with offenders after an offence has been committed.

The central prison-relevant aims are retribution, deterrence, incapacitation and rehabilitation. Reparation is a wider sentencing aim that also helps explain restorative approaches. An aim states what a sentence is intended to achieve; evidence is needed to judge whether it succeeds.

The key exam move is to separate aims from effects. Custody may aim to deter, protect and rehabilitate, but it can also create psychological effects that make rehabilitation harder.

Worked application: Sam receives a six-month prison sentence for repeated theft. The sentence may be retributive because Sam is being punished, and it may incapacitate him while he is in prison. But if Sam loses housing, becomes more anxious and mixes with more experienced offenders, the sentence may not support rehabilitation.

Judging the outcome: custodial sentencing is not one method with one outcome. A short sentence for a low-risk offender, a long sentence for a violent offender, and secure treatment for someone with complex mental health needs may have very different psychological effects. Good answers avoid saying "prison works" or "prison never works" without specifying the aim being judged.

Psychological Effects Of Custody

Custody is not only a legal punishment. It is also a powerful social environment. Psychological effects can be positive if custody gives structure, safety and treatment, but AQA answers usually focus on the risks: stress, depression, self-harm, institutionalisation and prisonisation.

One obvious effect is psychological distress. Prison involves loss of liberty, separation from family, reduced privacy, noise, threat, uncertainty and limited control. The Ministry of Justice's statistics for England and Wales provide a dated example: in the 12 months to December 2025 there were 72,753 reported self-harm incidents in prisons, and the rate of self-harm in women's establishments was more than nine times the rate in men's establishments. These are incidents, not 72,753 different people: one person can contribute several incidents. The number establishes the scale of recorded harm in this setting; it is not by itself a test of whether custody increased an individual's risk. Comparing rates, rather than raw totals, also matters when establishments differ in population size. Differences between groups may reflect prior vulnerabilities, conditions, reporting and repeated incidents as well as effects of imprisonment.

Custody can also produce loss of autonomy. Prisoners may have decisions about movement, food, work, sleep, visits and possessions controlled by the institution. Haney describes this as part of institutionalisation: prisoners may become dependent on institutional structure and find ordinary decision-making harder after release.

A third effect is hypervigilance and mistrust. In a threatening environment, constantly scanning for danger can be adaptive in custody. The problem is that this habit may continue outside prison, making family, work and community relationships harder.

A fourth effect is prisonisation. Offenders may learn the informal norms of prison culture: do not appear weak, do not trust staff, settle conflict through threat, and value status among other prisoners. This can clash with rehabilitation because the behaviour that helps a person survive in custody may be the opposite of what helps them live safely in the community.

What the records establish: current official statistics on self-harm, assaults and deaths make the psychological-effects argument concrete. They stop the answer becoming a vague claim that "prison is stressful".

Limitation: prison samples already contain high levels of pre-existing trauma, poverty, substance misuse, mental health difficulty and previous offending. Therefore, evidence of distress in custody does not always show that custody alone caused the distress. A precise answer says custody can worsen, trigger or maintain problems, rather than assuming every problem began in prison.

Social implications: this topic is socially sensitive. If psychological effects are ignored, policy may overestimate the rehabilitative value of custody. If the harms are overstated, the needs of victims and public protection may be underplayed. A balanced answer weighs both sides.

Behaviour Modification In Custody

Behaviour modification in custody is usually taught through token economies. It is a behaviourist intervention based on operant conditioning.

In a prison token economy, staff first identify target behaviours, such as attending education, following rules, completing work, keeping a cell tidy, using respectful communication or avoiding aggression. When the behaviour occurs, the offender receives a token. The token is a secondary reinforcer because its rewarding value is learned through association, but it can be exchanged for back-up reinforcers such as extra recreation, phone credit, preferred activities or small approved items.

The explanation: the behaviourist chain.

1. Target behaviour is operationalised so staff can observe it reliably.
2. The offender performs the target behaviour.
3. A token is given as immediate positive reinforcement.
4. Tokens are exchanged for back-up reinforcers.
5. The target behaviour becomes more likely in custody.

Research evidence: Hobbs and Holt (1976) introduced a token economy with 125 adolescent males in a state correctional institution. The programme targeted social behaviour, rule following and task completion. It was introduced across three cottages, with a fourth comparison cottage. Appropriate behaviour increased when the token programme was introduced, and the researchers collected data across 14 months.

The staggered introduction in Hobbs and Holt matters: if behaviour improves when the programme begins in each separate cottage, a single calendar event is a less convincing explanation than if every cottage changed at once. The comparison cottage gives a further check. However, this was not random allocation of a national prison sample, and the measured outcome was institutional behaviour. It cannot establish that adults will offend less after release.

Strength: token economies are practical in custody because they target observable behaviour and can be implemented by trained staff across a whole unit. They can make prison management less dependent on punishment by rewarding pro-social behaviour.

Limitation: surface change. Token economies may improve behaviour inside the institution without changing the underlying reasons for offending, such as anger, hostile thinking, addiction or pro-criminal peers. This means generalisation to the community is uncertain.

Limitation: ethics and power. In custody, access to privileges is controlled by the institution. If basic goods are used as rewards or removed as costs, behaviour modification can become coercive. The most ethical programmes use clear rules, meaningful but non-essential rewards, staff consistency and appeal procedures.

Limitation: implementation. Token economies depend on staff training, reliable observation, consistent reinforcement and rewards that offenders value. If staff apply rules inconsistently, offenders may see the system as unfair and the reinforcement effect weakens.

Anger Management

Anger management programmes are psychological interventions designed to reduce angry arousal and improve control over aggressive impulses. They are usually based on cognitive behavioural therapy.
