To complement the evidence-based practice paradigm, the authors argued for a core outcome measure to provide practice-based evidence for the psychological therapies. Utility requires instruments that are acceptable scientifically, as well as to service users, and a coordinated implementation of the measure at a national level. The development of the(More)
BACKGROUND An acceptable, standardised outcome measure to assess efficacy and effectiveness is needed across multiple disciplines offering psychological therapies. AIMS To present psychometric data on reliability, validity and sensitivity to change for the CORE-OM (Clinical Outcomes in Routine Evaluation--Outcome Measure). METHOD A 34-item self-report(More)

Each of 5 clinician-investigators treated clients in all 4 treatment conditions. On most measures, CB and PI were equally effective, irrespective of(More)

Sudden gains--large, enduring reductions in symptom intensity from one session to the next--were identified by T. Z. Tang and R. J. DeRubeis (1999b) on the basis of data from 2 manualized clinical trials of cognitive therapy for depression. The authors found similar sudden gains among clients with a variety of disorders treated with a variety of approaches(More)
We propose 4 parameters that describe the course of change in the subjective intensity of personal problems during psychotherapy: (a) the problem's initial severity; (b) its rate of change (deterioration or improvement); (c) its instability (day-to-day variability in intensity); and (d) its curve (change in the rate of change during treatment). We(More)
The purpose of this study was to identify the best fitting hierarchical factor structure of the subscales for personality disorders developed from the Inventory of Interpersonal Problems (IIP). In earlier work, 5 subscales associated with a diagnosis of personality disorder (PD) had been developed. With data collected from 5 additional samples at 4 sites (N(More)
BACKGROUND Psychotherapy's equivalence paradox is that treatments have equivalently positive outcomes despite non-equivalent theories and techniques. We compared the outcomes of contrasting approaches practised in routine care. METHOD Patients (n = 1309) who received cognitive-behavioural therapy (CBT), person-centred therapy (PCT) and psychodynamic(More)
BACKGROUND Little research on the value of Health of the Nation Outcome Scales (HoNOS) has occurred in out-patient settings, particularly psychotherapy services. AIMS To determine whether HoNOS provides an adequate assessment for psychotherapy services which is sensitive to change. METHODS HoNOS ratings from 1688 patients from eight out-patient(More)
