Non-attendance at counselling therapy in cocaine-using methadone-maintained patients: lessons learnt from an abandoned randomised controlled trial

Background:

Recently, the authors commenced a randomised controlled trial to study the effectiveness of cognitive behavioural coping skills (CBCS) to reduce cocaine usage in methadone-maintained patients’ in a clinical setting by assessing attendance at treatment sessions and outcomes in terms of cocaine use. However, recruitment into the study stopped when it became apparent that attendance at counselling sessions was poor.

Aims:

The aim of the current study was to determine the reasons for both non-attendance and attendance from a patient’s perspective at counselling sessions.

Methods:

A cross-sectional design was employed whereby participants who were recruited for the original study were interviewed utilising a semi-structured interview format.
Results: Motivational inconsistencies were most frequently cited as the reason for dropping out of counselling, whereas a good relationship with staff was cited by attenders as the most important factors which aided their attendance at counselling sessions.

Conclusions:

Selecting opiate-dependent methadone-maintained cocaine abusers on the basis of their urine toxicology and offering them counselling as a way of reducing their harmful drug use did not prove efficacious. Attempting to address cocaine misuse within this cohort may need a more stepped approach including brief interventions, such as motivational interviewing, or other enhancers of motivation before we can test the effectiveness of CBCS in this population.
