Objective: Rates of non-attendance for psychotherapy hinder the effective delivery of evidencebased treatments. Although many strategies have been developed to increase attendance, the effectiveness of these strategies has not been quantified. The aim of the present study was to undertake a meta-analysis of rigorously controlled studies to quantify the effects of interventions to promote psychotherapy attendance.Method: The inclusion criteria were that studies (1) concerned attendance at individual or group psychotherapy by adults, (2) used a randomised controlled trial design to test an attendance strategy, and (3) used an objective measure of attendance. Computerised literature searches and hand searching resulted in a total of 31 RCTs that involved 33 independent tests of strategies for reducing treatment refusal and premature termination (N = 4,422). Effect sizes from individual studies were meta-analysed and moderator analyses were conducted.Results: Interventions had a small-to-medium effect on attendance across studies (d + = .38).Interventions to reduce treatment refusal and premature termination were similarly effective (d + = .37 and .39, respectively). Choice of appointment time or therapist, motivational interventions, preparation for psychotherapy, informational interventions, attendance reminders, and case management were the most effective strategies. Diagnosis also moderated effect sizes; samples with a single diagnosis benefited more from attendance interventions than samples that had a variety of diagnoses.Conclusions: Interventions to increase attendance at adult psychotherapy are moderately effective.However, relatively few studies met the strict study inclusion criteria. Further methodologically sound and theoretically informed interventions geared at increasing attendance are required.
META-ANALYSIS OF PSYCHOTHERAPY ATTENDANCE 3Interventions to Increase Attendance at Psychotherapy:A Meta-Analysis of Randomised Controlled Trials A substantial proportion of clinical time is wasted because of patient non-attendance at scheduled adult psychotherapy appointments (Pekarik, 1985). The financial costs of nonattendance are marked (Hicks & Hickman, 1995; Kleine, Stone, Hicks & Pritchard, 2003), with patients not receiving help (Joshi, Maisami & Coyle, 1986) and therapists losing confidence as a result (Sledge, Moras, Hartley & Levine, 1990). Service efficiency is impaired when nonattendance rates are high (Rusius, 1995). Garfield (1994) noted that some patients fail to attend at assessment and essentially reject treatment. Hampton-Robb, Qualls, and Compton (2003) estimated that such treatment refusal (TR) occurs for 40% of referrals, on average. Premature termination (PT) occurs when patients fail to complete agreed treatment contracts (i.e., they 'drop-out' of therapy). A meta-analysis of 123 studies reported a PT rate of 46.8% (Wierzbicki & Pekarik, 1993) across treatment modalities. High PT rates are troubling in light of evidence that PT is associated with poor clinical outcome (Barret...
