Introduction Many child and adolescent mental health services (CAMHS) struggle with increasing demands, long waiting lists and keeping waiting times for first appointments to within government guidelines. An audit of 7,000 successive new referrals to CAMHS found that the average number of attendances was 4.52 and only 11% of families were still in treatment at six months. Eighty-five per cent of families attended six sessions or fewer and 32% were only seen once (Hoare et al, 1996). Clinicians may believe that families and children need long-term treatment, yet we know from our experience and the literature that most will not engage in long-term interventions. Dropout rates increase as the waiting time for an initial appointment increases, and 30 weeks appears a crucial cut-off after which most families give up. Providing brief, focused interventions is one approach and some CAMH services have found offering as few as three sessions to be helpful. Seeing families relatively quickly, yet perhaps not sooner than a month, may be ideal (Foreman & Hanna, 2000). Combining the two strategies results in a potential model for providing brief, focused interventions over three to eight sessions within a period of four to 30 weeks of referral. There is a growing literature on the use of brief interventions for managing child and adolescent mental health problems. Stallard and Sayers (1998) describe an opt-in, brief three-session problemsolving, empowerment approach developed in their CAMHS. Average initial HoNOSCA scores were 9.23 (range: three to 25). The majority of families were satisfied with the service they received and both they and their clinicians indicated an improvement in symptoms at the end of contact. Goldberg and Campbell (1997) also describe a three-session approach developed in their community adolescent service. They use techniques from solution-focused therapy, brief motivational interviewing, interventive interviewing and cognitive behavioural strategies in a collaborative model of working with families. Both they and Weltner (1982), who also uses a three-session model, report that the method produces change and is seen as helpful by families. Spoth et al (2000) describe a seven-session intervention for parents and young adolescents that was successful in reducing aggressive and hostile behaviours. Partridge et al (1999) developed a brief, focused family therapy service and reported that 48% of families were seen on one occasion, 26% on two occasions, 15% on three occasions and 11% on four or more occasions. Of the 30 families whose treatment was completed, only two were re-referred within a year of discharge. Allison et al (2000) reported that brief therapy resulted in significant improvement in the majority of the children seen in their service but
