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)
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)
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)
OBJECTIVE To evaluate benefits for postnatal women of two psychologically informed interventions by health visitors. DESIGN Prospective cluster trial randomised by general practice, with 18 month follow-up. SETTING 101 general practices in Trent, England. PARTICIPANTS 2749 women allocated to intervention, 1335 to control. INTERVENTION Health(More)
Of 76 clients receiving 8-20 sessions of cognitive therapy (CT) in a joint university and a national health service clinic, 31 experienced sudden gains that appeared very similar to those first reported in clinical trials of CT by T. Z. Tang and R. J. DeRubeis (1999) and subsequently replicated in other studies. The sudden gains appeared less stable in the(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)
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)
A total of 117 depressed clients, stratified for severity, completed 8 or 16 sessions of manualized treatment, either cognitive-behavioral psychotherapy (CB) or psychodynamic-interpersonal psychotherapy (PI). Each of 5 clinician-investigators treated clients in all 4 treatment conditions. On most measures, CB and PI were equally effective, irrespective of(More)
BACKGROUND Collaborative care is an effective intervention for depression which includes both organizational and patient-level intervention components. The effect in the UK is unknown, as is whether cluster- or patient-randomization would be the most appropriate design for a Phase III clinical trial. METHOD We undertook a Phase II patient-level randomized(More)
