Background: Despite developing interest in treatments encouraging flourishing in Substance Use Disorder there is little research on their efficacy.

Methods: A preliminary randomised controlled study (wait-list or immediate intervention) (n=72) and cohort study (n= 60) evaluated outcomes in alcohol misusers of The Rediscovery Process (TRP), a flourishing focussed approach, compared to treatment as usual (TAU). Alcohol use, flourishing, impulsivity and recovery capital were analysed pre-, 1 and 3-month postintervention.

Results: The studies found TRP significantly decreased alcohol use and impulsivity, and increased flourishing and some elements of recovery capital, compared to TAU and these changes were maintained at 1 and 3-months post-intervention, compared to pre-intervention.

Discussion: Therefore TRP, compared to TAU, significantly improves a range of important alcohol misuse outcomes that are maintained over the 3-month period.

Conclusions: These results help bridge the gap between addressing the psychopathology in substance use and the recent interest in increasing flourishing.

Keywords: Positive psychology; flourishing; recovery capital; alcohol use; impulsivity.

Association Study

Association between impulsivity and flourishing in Substance Use Disorders (SUD): bridging the gap between pathology focused psychology and positive psychology?

Introduction: Impulsivity is identified with the development and maintenance of substance use disorders (SUD). Although Barratt originally theorised it to be a relatively static trait, addressing impulsivity has been an important SUD treatment aim. The continuing poor outcomes for those in treatment has raised interest in recovery-based and Positive Psychology interventions (PPI) to SUD and the importance of flourishing. There has been concern that this might supplant impulsivity reducing approaches, however little is known about how flourishing and impulsivity interrelate in SUD. This paper reviewed the literature and evaluated that relationship in two clinical studies. It concludes that there is an absence of reported research as to how impulsivity and flourishing interrelate in SUD and identified a strong to moderate, significant negative association between changes in impulsivity and flourishing in those with SUD, a finding that had not been previously reported. These findings add weight to the argument that impulsivity may be a more dynamic entity than originally theorised and may suggest a route for integration of more pathology focused psychology and Positive Psychology approaches to SUD.

Systematic Review

By Parker, Banbury and Chandler, 2018, into the Utility of Measuring Flourishing in Substance Use is published in the European Journal of Positive Psychology 

Pilot study

In 2013 a 6 month pilot of the Rediscovery Process was delivered in Tower Hamlets Community Drug Team (CDT).  Data was collected together with feedback from focus groups and case studies (full Pilot data can be found here).

Summary of data

All community clients that took TRP and were followed up made changes in their drug usage and in their lives.

The vast majority sought and gained employment, enrolled as students or took on volunteering positions

They also reported positive changes in their interpersonal relationships and self-esteem levels.

Two sets of figures from the data stand out as a good guide to the effects of the TRP:

1) Out of 20 clients using, the TOP forms showed that 11 (55%) had reduced and 7 (35%) had stopped their drug/alcohol use (90% in total).

2) Pre TRP only 3 of the 22 (14%) were in employment (or seeking work), education or volunteering data; post TRP this had increased to 18 (73%).


We believe these outcomes demonstrate the intention of TRP well: that through teaching self-empowerment strategies that are effective and simple to apply, the TRP can help individuals to rebuild their internal and external recovery capital, and make sustainable change to their drug or alcohol use.
