Client-focused research systems have been developed to monitor and provide feedback information about clients’ progress in psychotherapy as a method of enhancing outcome for those who are predicted to be treatment failures. In the current study, the authors examined whether feedback regarding client progress and the use of clinical support tools (CSTs)(More)
Enhancing treatment outcomes for clients who are predicted to deteriorate before leaving treatment has important implications for quality of client care. The effects of three interventions aimed at reducing client deterioration were examined in a sample of 1,374 clients whose outcome was contrasted across experimental groups and with a no-feedback/ archival(More)
Patient-focused research attempts to provide information that answers the question: Is this treatment benefiting this patient? Although several systems have been developed to monitor and provide feedback about a patient's response to psychotherapy, few if any have been tested empirically. The current study divided 609 patients into four groups (two(More)
Many branches of medicine rely heavily on lab tests to monitor client treatment response and use this information to modify their treatment. By contrast, those who offer psychological interventions seldom rely on formal assessments (lab tests) to monitor their clients' response to treatment. Data are presented that demonstrate that clinicians rarely(More)
Most research on the dose-effect model of change has combined data across patients who vary in their total dose of treatment and has implicitly assumed that the rate of change during therapy is constant across doses. In contrast, the good-enough level model predicts that rate of change will be related to total dose of therapy. In this study, the authors(More)
OBJECTIVE Psychotherapy researchers have long questioned whether increased therapist experience is linked to improved outcomes. Despite numerous cross-sectional studies examining this question, no large-scale longitudinal study has assessed within-therapist changes in outcomes over time. METHOD The present study examined changes in psychotherapists'(More)
OBJECTIVE Differences between therapists in their average outcomes (i.e., therapist effects) have become a topic of increasing interest in psychotherapy research in the past decade. Relatively little work, however, has moved beyond identifying the presence of significant between-therapist variability in patient outcomes. The current study sought to examine(More)
This paper aims to provide researchers with practical information on sample sizes for accurate estimations of therapist effects (TEs). The investigations are based on an integrated sample of 48,648 patients treated by 1800 therapists. Multilevel modeling and resampling were used to realize varying sample size conditions to generate empirical estimates of(More)
As established in several studies, therapists differ in effectiveness. A vital research task now is to understand what characterizes more or less effective therapists, and investigate whether this differential effectiveness systematically depends on client factors, such as the type of mental health problem. The purpose of the current study was to examine(More)
