The objective of the study was to qualitatively evaluate the managerial and organisational issues associated with service quality in a privately funded alcohol treatment centre in the UK. Two different groups of participants at a private treatment clinic were interviewed. The first group comprised 25 of its patients. The second group comprised 15 staff members of the same clinic. All 40 interviews were transcribed and a thematic analysis was performed on the data to reveal the key themes. Six themes emerged from the interviews amongst patients and staff of the treatment clinic. The six themes were: (1) the fellowship of patients, (2) professionalism, (3) process and measurement, (4) incarceration, (5) empathy gap, and (6) access to treatment. Findings suggested there was a strong emphasis on management of the service delivery with established quality systems and performance measurement systems in place. The two service quality gaps, suggested by the research, were the rigid delivery of service and a lack of empathetic relationships with patients. Furthermore, by evaluating the service quality delivery from the service user's perspective, a voice was given to a group of patients, who in research terms have gone largely unheard.Keywords Problem drinking . Addiction . Addiction services . Revolving door . Service quality Service quality can be conceptualised as an evaluation or an attitude about a service offering or delivery but also viewed as an attribute that "closes the loop between evaluation and the choice process" (Bateson 1995; p.558). In the case of problem drinkers seeking treatment, the loop may be difficult to close because the number of services available makes it more complex. Many problem drinkers may not possess the physical and/or mental capacity to make appropriate choices (Edwards et al. 2003) and numerous choices of treatment services allows problem drinkers to move from one service to another and back again, creating a 'revolving door' practice. The 'revolving door' concept also shapes Int J Ment Health Addiction
