Understanding prison violence

Prison disturbances are associated with physically poor conditions, highly controlling regimes and the uneven application of rules, finds Professor James McGuire.

A rapid evidence assessment

HM Prison and Probation Service (HMPPS) has just (6 September 2018) published a rapid evidence assessment by Professor James McGuire into our understanding of prison violence.

The REA set out to answer five questions:

  1. Who (which prisoners) are the most likely to commit incidents of violent disorder within establishments?
  2. When are incidents of prison violence most likely to occur?
  3. Where are the incidents of prison violence most likely to occur?
  4. Which are the strongest drivers of prison violence, taking into account interactions amongst the various drivers (covering the dimensions of who, when and where)?
  5. What are the key lessons for operational policy and/or delivery in terms of mitigating and reducing the risk of violent disorder? Are there any clear protective factors?

The REA is based on 97 studies, the overwhelming majority of which (87, or almost 90%) were carried out in the United States. Six were conducted in England and Wales, two in Switzerland, and one each in Slovenia and Spain.

The findings are set out below.

Which prisoners are most likely to be violent?

One quarter of the studies reviewed had focused on individual (‘imported’) variables. Several of the main variables tested in these studies emerge as having a consistent and sometimes very strong relationship with involvement in violent infractions. The factor which emerged most regularly was younger age. This usually means that those aged 21 or less have higher rates of violent indiscipline than those aged 22-35 or older, but various cut-offs were used in other studies. The other most widely reported variables that were regularly associated with prison violence were a pre-existing record of violent indiscipline in prison and gang membership.
Other variables had a less consistent pattern of association, where in some but not all studies they were found to predict prison violence. Such variables included: having a previous conviction for a violent offence, racial/ethnic grouping, shorter sentence length, and having served less time (at the moment of data collection). Prisoners without hope of release (sentenced to life without parole) were, contrary to expectations, not more likely to be involved in prison violence because they had ‘nothing to lose’. Many variables, such as racial/ethnic group, had effects that were moderated by other factors and the patterning of this varied across studies making clear conclusions difficult to draw.

In the mainly US literature, membership of a prison gang appeared to be more important than being a gang member in the community.

Administrative, procedural and managerial factors

This category refers to decisions made by prison managers regarding different aspects of how an institution is run including: the amount of time prisoners are out of their cells, to their freedom of movement, the availability of different resources and facilities, the extent of choice over daily activities, or the experience and skill levels of front-line staff. 

Higher security levels are accompanied by higher rates of violence. It has been suggested that this may be an effect of labelling: an assignment to a high level of security conveys an impression of being ‘hard to handle’ which an individual absorbs and acts upon.

There was evidence that the number of violent infractions was higher when a prison’s environmental controls were lower, yet in another study there was no significant effect of coercive controls, but a positive effect for use of remunerative controls — so prisoners in paid employment were less likely to assault staff (with other variables controlled).

Aspects of administrative control (how well organised the prison administration is) and procedural justice (the extent to which prisoners experience prison processes as fair) have been found to be linked to violent misconduct, notably prison homicides. When a prison contains a high proportion of prohibited groups (for example, gangs or belief groups with a specific agenda pursuing aggression towards others), and there is inconsistency between staff ranks in the use of discipline (lower level decisions are not upheld by senior managers), serious violence may be more likely. In contrast, some administrative approaches characterised as embodying procedural justice are associated with lower rates of infraction.

Prison conditions & situational factors

Two studies reported clear findings that better physical conditions in prison were associated with lower levels of violence, and that prisoners experiencing higher levels of hardship had higher levels of misconduct. Another study found a significant association between deprivation (measured as a composite of five factors) and violence by prisoners against staff. There was also a firm finding from a very large study (120,855 prisoners across 156 facilities) that being amongst prisoners classified as requiring higher levels of security (higher custody scores) was associated with greater likelihood of violence. 

A study of the effect of prison visits found a pattern in which there was a gradual average decrease (of 67%) in violent incidents during the period six weeks before a visit, but a rapid escalation (by 61%) in the week afterwards. This was followed by a decline to the ‘baseline’ level that had prevailed six weeks before the visit.

Overcrowding

Perhaps surprisingly, evidence that crowding in and of itself was a direct cause of violence was fairly weak. Research suggested that the effects of crowding are mediated through staff-prisoner interactions and that the crucial factor in maintaining order is the availability and the skills of unit staff.

How to reduce violence

Taking account of the fact that prisons cannot select those who are sent to custody, Professor McGuire recommends that a policy designed to reduce violence focuses on situational control aspects of day-to-day prison management. 

He concludes:

That would require staff training in the use of styles and patterns of interaction that both wield authority alongside instilling respect. When incidents occur in an establishment, there should be recording and analysis of regular flashpoints according to prison routines and combinations of prisoner interactions. This will allow for consideration of alternative routines that could keep potential conflicts to a minimum.

1 thought on “Understanding prison violence”

  1. In the UK this is NOT the case. That is, prisons can and do select who they want. Governors routinely contact each other about which prisoner to send to which prison. This is done as per the “moving” or “transfer” process. This process can be initiated by staff or the prisoner. The receiving prison must accept the new prisoner. If there is a history of violence(in prison) then that prison Governor can and does refuse to accept that prisoner. This means that Professor McGuire’s study misses a key factor in the cause and control of prison violence. It must also be pointed out here that when a prisoner is refused a move then he can respond violently. That is, this is yet another cause for a violent incident. It is, from my personal experience, the interaction with staff that causes the violence in prisoners. The drug taking starts because of the interaction with prison staff. That is, the interaction with prison staff is so poor that the prisoner feels there is nothing to loose in taking drugs. This, of course, brings him into contact with the drug dealers whose motivation for dealing drugs is to commit violence.
    It must also be pointed out that often when prisoners are asked to supply answers to a “study” they will give the opposite answer to what they actually think. This is to disrupt the work of the study. They do this because the study is funded by the “authorities”. And because of the terrible abuses enacted upon people in public life and in prison, by the authorities, all trust in the “authorities” is and has been lost, and any opportunity to “get back at the authorities” is taken.
    Again I don’t think Professor McGuire has considered this either. A rapid evidence assessment, is also, in my view not appropriate. It will, without doubt, give some results wrongly. What response will the Department for Justice make to this study? The prisoners will suffer, no doubt.
