Contingency management in addiction research

What is Contingency management?

Contingency management is a treatment strategy that aims to increase motivation and encourage positive behaviours. It’s based on the simple behavioural principle that if a behaviour is rewarded it is more likely to be repeated. In psychology this is known as operant conditioning.  This principle is used in everyday life.

Examples of contingency management in everyday life:

  • Parents use pocket money (incentive) to encourage children to tidy their bedrooms (positive behaviour)
  • Employers use salaries and bonuses (incentive) to reward high performance and hitting targets (positive behaviour)

 

Contingency management as an intervention in addiction treatment

In addiction treatment contingency management can be used to encourage and reward behaviours that are consistent with a drug free lifestyle. Rewards are often in the form of vouchers or gift cards that can be exchanged for goods and services that are also compatible with a drug free way of life.

 

Contingency management as an intervention in addiction treatment

Examples of contingency management in addictions treatment:

  • Service users are rewarded for providing urine specimens that test negative for drugs, encouraging abstinence.
  • Service users are rewarded for attending clinic appointments, encouraging engagement with treatment

 

Contingency management in addiction treatment – is it controversial?

There is a controversy surrounding the use of contingency management in addictions services. One of the main concerns is that the financial incentives given to service users could be used to buy drugs. Another concern is that by encouraging behaviour change with external rewards the participants’ internal motivation could be reduced, which could lead to problems with motivation in the long term. Contingency management has also been criticised because it not only costs a lot with regards to the incentives given but also with regards to the amount of time it takes for it to be administered. However there is scientific evidence to suggest that contingency management is worth the investment.

Contingency management and addictions research – The ADAM trial

Research studies have previously demonstrated that incentive-based treatments are successful in motivating people to remain abstinent from drugs and remain in treatment. These research studies have been carried out with a variety of drugs including stimulants, opioids, marijuana, nicotine and alcohol.

One aim of the ADAM Trial is to find out whether contingency management is successful at encouraging participants to engage with the telephone support provided by the pharmacist. Participants who are randomised to receive both the telephone support and the incentive, which is called the personal achievement award, will be rewarded with a £5 Love2Shop voucher for each of the 12 telephone call they complete over the 6 months of the study. In addition to this participants will be rewarded with a bonus each time they complete four calls in a row. A total of £120 can be earned for completing all support sessions and these vouchers can be spent in a range of places including high street stores, supermarkets (excluding cigarettes and alcohol) and on days out.

 

Personal achievement award

Sessions completed Incentive Bonus Running total
1 £5 £5
2 £5 £10
3 £5 £15
4 £5 £10 £30
5 £5 £35
6 £5 £40
7 £5 £45
8 £5 £20 £70
9 £5 £75
10 £5 £80
11 £5 £85
12 £5 £30 £120
Total £60 £60 £120

 

By carrying out this research we are able to learn about how effective the personal achievement award is at increasing engagement with telephone based support for alcohol dependence.

Congratulations to the ADAM Trial Manager Dr Kim Donoghue on the birth of her baby boy in early June

We’d like to give a warm welcome to Dr Sadie Boniface who is in post to cover Kim’s maternity leave – welcome to the team Sadie!

Building links with CNWL addiction specialist services

To continue the further development of our telephone intervention pharmacists we conducted  a training and networking event  with the Central and North West London (CNWL) Addiction Specialist Pharmacists. This session helped build links and relationships between our trial pharmacists and addiction specialist pharmacists. This meeting provided a unique learning opportunity for the telephone pharmacists to gain insight and understanding of the range of support given by pharmacists in drug and alcohol service. Many thanks to Fahreen Hasham, Noor Assadi and Soyar Sherkat who shared their time and wisdom with us.

NIHR New Media Competition

The ADAM team entered the NIHR New Media Competition, and created a 2 minute video about the study and Patient and Public Involvement in developing the trial.  Unfortunately we were not successful in being shortlisted, but you can read the story of creating the video in the ADAM Study Blog.
