I have carried out a number of research studies in the field of substance misuse and mental health. These include:
  • Service and treatment system evaluations
  • Literature reviews
  • Desktop reviews
  • Needs analysis
  • Guidance papers 
This work is often linked to the continued development of services (see Consultancy section).  Here are some samples of treatment evaluation studies I have undertaken or contributed to.  Please contact me to discuss any research or evaluation needs.
Drug and Alcohol Services
Long term opiate users on substitute prescribing often remain within treatment settings for long periods of time.  Whilst it is important to recognise that not all opiate users are liable to remit from use, services can be re-configured in order to increase successful treatment completions for those opiate users who do want to make substantial lifestyle change.  In response I developed a new treatment framework to enhance treatment gains, reduce caseload management and re-orientate services towards a recovery.  These proposals can be downloaded here.  This new model increased treatment completion rates for opiates from almost zero to 14 per cent of case load per year.  The evaluation of this treatment system can be reviewed here:

Young People's Services
There is a paucity of research on young people with substance misuse problems.  Based on research in adolescent development, the evolution of drug and alcohol problems as well long term longditudinal studies, a framework for young people services (click here) I have developed an adolescent informed treatment system. The viability of the new model was also tested as part of a Needs Analysis before implementation, these findings are presented here:​

This new approach tripled young people's outcomes and they demonstrated double the treatment completion rate of young people in England.  The evaluation study can be downloaded here:
Choices: A Review of a Developmentally Informed Substance Misuse Treatment System for Young People (May 2011-Dec 2012). Phil Harris
This new system as continued to evolve across Wales & England, and notably with the YZUP team in Cornwall.  This has led to greater definition of treatment approaches for Externalised and Internalised youth, as well as the development of a suite of assessment tools.

Concerned Other Services
The Parents and Carers Training (PACT) programme was designed to support concerned others to make effective changes to thier own life as well as thier loved ones.  Extensive evaluations were carried during the the development of concerned other services and informed 'The Concerned Other:  Clincal Manual.' Two research evaluations are included here.   One is based on a dedicated concerned other service that piloted the PACT programme in South Wales and group work version of the PACT programme piloted in Somerset.

Changes in social policy now require greater focus on measuring client outcomes. However, outcome tools are not well understood.  This has led to the adoption of many clinical tools that are not validated.  Without validation, the data these tools produce is highly questionable.  As commissioning decisions are often made on this information, getting accurate data is vital.  Here is a brief guide to outcome tools and the validation process.
