Is there evidence that cognitive behaviour therapy is an effective treatment for schizophrenia? A cautious or cautionary tale?

Schizophrenia is a severe and disabling disorder with considerable psychological, social and economic costs. Over the last 15 years there has been a significant development in the use of cognitive behaviour therapy for psychosis (CBTp) in the treatment of schizophrenia, with 20 randomised controlled trials having been published. The majority of this work has been with alleviating medication resistant symptoms in chronic patients, but preliminary work has also been carried out with speeding recovery in acute schizophrenia and in relapse prevention and early intervention. A review of these studies indicates modest effect sizes, with the strongest evidence available for chronic patients. There is evidence that the effect size of the trials is significantly and negatively correlated to their methodological quality. We conclude cautiously that overall there is good evidence for the efficacy and effectiveness of CBTp in the treatment of schizophrenia.

Unexplored issues and future directions in social phobia research.

There have been significant advances in recent years in the understanding and treatment of social phobia, which are summarised in this Special Issue. This paper outlines and describes some further priority areas for future research. It is suggested that social phobia should be investigated as a developmental condition, with special attention to the first two years of life; and subtypes of social phobia be further explored and their implication for treatment. Social phobia is often comorbid with other disorders and its relationship with these disorders warrants further investigation with respect to causality and treatment implications. Lastly, the investigation of social phobia within a health services research context is highlighted with the necessity of refining the design of clinical trials to establish the efficacy and effectiveness of current treatments.

Cognitive-behavioural therapy in first-episode and early schizophrenia. 18-month follow-up of a randomised controlled trial.

BACKGROUND: The initial phase of a trial of cognitive-behavioural therapy (CBT) for acutely ill patients with schizophrenia of recent onset showed that it speeded recovery. AIMS: To test the hypothesis that CBT in addition to treatment as usual (TAU) during the first or second acute episode of schizophrenia will confer clinical benefit over a follow-up period. METHOD: This was an 18-month follow-up of a multicentre prospective trial of CBT or supportive counselling administered as an adjunct to TAU, compared with TAU alone, for patients hospitalised for an acute episode of schizophrenia of recent onset. Primary outcomes were total and positive symptom scales, time to relapse and re-hospitalisation. RESULTS: There were significant advantages for CBT and supportive counselling over TAU alone on symptom measures at 18 months but no group difference was seen for relapse or re-hospitalisation. There was a significant centre-treatment interaction, reflecting centre differences in the effect of introducing either treatment, but not in the comparison of CBT and supportive counselling. Medication dosage and compliance did not explain group differences. CONCLUSIONS: Adjunctive psychological treatments can have a beneficial long-term effect on symptom reduction.

Social support, anxiety and depression after chemotherapy for ovarian cancer: a prospective study.

OBJECTIVES: We aimed to describe the levels of anxiety and depression in patients during the 3 month period following the end of chemotherapy treatment and to identify factors that predict psychological morbidity. METHOD: We performed a prospective study in women with ovarian cancer to determine the changes in psychological status in the 3 months following completion of chemotherapy. Sixty-three consecutive patients were assessed at the completion of chemotherapy (Time 1) and 57 at 3 months follow-up (Time 2). Relevant disease and patient characteristics were recorded and patients were assessed at Time 1 for anxiety, depression and their perception of emotional support, an index of their psychosocial environment. Anxiety and depression were re-assessed at Time 2. RESULTS: The results indicate significant initial psychological morbidity, with clinical caseness for anxiety (38%) and depression (33%) being common. Follow-up at Time 2 shows that patients undergo a significant reduction in cases (19%) and symptoms of depression but an increase in cases of anxiety (47%). The principal factors associated with symptoms of anxiety at Time 2 were poor perceived social support, increased intrusive thoughts and, to a lesser extent, younger age. Medical parameters, such as the stage of disease, response of the cancer to treatment, Ca125 (a tumour glycoprotein) and Karnofsky Performance status (a measure of how well the patients is) were not associated with worse psychological outcome. CONCLUSION: These data show for the first time that social support and intrusive thoughts, rather than physical parameters, are the principal determinants of psychological morbidity in patients with ovarian cancer.

The cognitive-behavioural treatment of low self-esteem in psychotic patients: a pilot study.

Low self esteem in individuals with a psychotic disorder is common and may be related to poorer clinical outcomes. However, there has been little research on devising treatment methods to improve self-esteem either generally or in psychotic patients in particular. The aims of this study were to evaluate the efficacy of a simple cognitive behavioural intervention to improve self esteem in psychotic patients who scored poorly on a self-esteem measure. This pilot study was a randomised control trial with a convenience sample of chronic psychotic inpatients. The cognitive behavioural self-esteem intervention, as an adjunct to treatment as usual (TAU), was compared to TAU alone in patients with psychosis. The individual self-esteem intervention as described by Tarrier (The use of coping strategies and self-regulation in the treatment of psychosis. (2001)) consisted of working with participants to elicit positive self-attributes and then identify specific behavioural examples to provide evidence of this attribute. Emphasis was given to any consequential change in the patient's belief that they had the attribute. The results indicated that this cognitive behavioural treatment for self-esteem used as an adjunct treatment in psychosis, resulted in clinical benefits in terms of increased self-esteem, decreased psychotic symptomatology and improved social functioning. These benefits were largely maintained at 3-month follow-up.

Posttraumatic stress disorder following medical illness and treatment.

Studies describing posttraumatic stress disorder (PTSD) as a result of physical illness and its treatment were reviewed. PTSD was described in studies investigating myocardial infarction (MI), cardiac surgery, haemorrhage and stroke, childbirth, miscarriage, abortion and gynaecological procedures, intensive care treatment, human immunodeficiency virus (HIV) infection, awareness under anaesthesia, and in a group of miscellaneous conditions. Cancer medicine was not included as it had been the subject of a recent review in this journal. Studies were reviewed in terms of the prevalence rates for PTSD, intrusive and avoidance symptoms, predictive and associated factors and the consequences of PTSD on healthcare utilization and outcome. There was considerable variability both in the study methodology and design and in the results. The highest prevalence rates were identified in patients treated in intensive care units (ICUs) and those with HIV infection. Irrespective of the physical illness, posttraumatic symptomatology is more common than PTSD caseness. Existing characteristics of the patient may well predispose individuals to the development of PTSD as do other factors such as poor social support and negative interactions with healthcare staff. Generally, the severity of the illness itself is not predictive of PTSD. Issues relating to sampling, attrition, diagnosis, the course of symptoms, aetiological pathways, and the consequences of the disorder are discussed. The presence of PTSD most probably influences the patient's use of healthcare resources and may affect their clinical outcome.

Cognitive behaviour therapy for posttraumatic stress disorder.

Following considerable empirical scrutiny, cognitive behaviour therapy (CBT) has proven to be a safe and effective treatment for posttraumatic stress disorder (PTSD). This article overviews the general principles of treatment and describes the components that comprise CBT for PTSD. We then move on to review the efficacy of CBT for the treatment of PTSD caused by various traumas, including assault, road traffic accident (RTA), combat, and terrorism. Recent advances in early intervention and in the treatment of disorders that are comorbid with PTSD are reviewed. Finally, future directions are discussed. In particular, it is proposed that randomised controlled trials (RCT) of CBT for PTSD must be conducted with enhanced methodological rigour and public health relevance.

Cognitive-behavioural therapy and motivational intervention for schizophrenia and substance misuse. 18-month outcomes of a randomised controlled trial.

BACKGROUND: Comorbid substance misuse in people with schizophrenia is associated with poor clinical and social outcomes. There are few studies of psychological treatments for this population and little long-term follow-up of their benefits. AIMS: To investigate symptom, substance use, functioning and health economy outcomes for patients with schizophrenia and their carers 18 months after a cognitive-behavioural treatment (CBT) programme. METHOD: Patients with dual diagnosis from a randomised controlled trial of motivational intervention, individual CBT and family intervention were assessed on multiple outcomes at 18-month follow-up. Carers were assessed on symptom, functioning and needs over 12 months. Health economy data were collected over 18 months. RESULTS: There were significant improvements in patient functioning compared with routine care over 18 months. No significant differences between treatment groups were found in carer or cost outcomes. CONCLUSIONS: The treatment programme was superior to routine care on outcomes relating to illness and service use, and the cost was comparable to the control treatment.

Self-esteem in schizophrenia: relationships between self-evaluation, family attitudes, and symptomatology.

Participants with schizophrenia (N = 59) were assessed on self-evaluation, symptomatology, and positive and negative affect (expressed emotion) from significant others. An interview-based measure of self-evaluation was used and two independent dimensions of self-esteem were derived: negative and positive evaluation of self. As predicted, negative self-evaluation was strongly associated with positive symptoms, a more critical attitude from family members was associated with greater negative self-evaluation, and analyses supported a model whereby the impact of criticism on patients' positive symptoms was mediated by its association with negative self-evaluation. The interview-based method of self-esteem assessment was found to be superior to the questionnaire because its predictive effects remained after depressed mood was accounted for.

Religious delusions in patients admitted to hospital with schizophrenia.

BACKGROUND: Religious delusions are clinically important because they may be associated with selfharm and poorer outcomes from treatment. They have not been extensively researched. This study sought to investigate the prevalence of religious delusions in a sample of patients admitted to hospital with schizophrenia, to describe these delusions and to compare the characteristics of the patients with religious delusions with schizophrenia patients with all other types of delusion. METHOD: A cross-sectional investigation was carried out. The prevalence of religious delusions was assessed and comparisons were made between religiously deluded patients and a control group on demographic, symptom, functioning and religious variables. One hundred and ninety-three subjects were examined of whom 24% had religious delusions. RESULTS: Patients with religious delusions had higher symptom scores (as measured by the PANSS), they were functioning less well (as measured by the GAF) and they were prescribed more medication than those patients with schizophrenia who had other types of delusion. CONCLUSION: It is concluded that religious delusions are commonly found in schizophrenia and that by comparison with other patients who have schizophrenia, those patients with religious delusions appear to be more severely ill. This warrants further investigation.

Expressed emotion and attributions in the carers of patients with Alzheimer's disease: the effect on carer burden.

Burden of care, expressed emotion (EE), causal attributions, and salivary cortisol were assessed in 100 carers of patients with Alzheimer's disease. Forty-one carers were rated high EE, which was associated with higher scores of carer distress and strain, and greater reports of noncognitive features in the patient, but not with cortisol levels. High EE carers made more attributions personal to, and controllable by, the patient for negative events. Critical carers made more attributions of the patient's behavior that was idiosyncratic. Warmth toward the patient was associated with the opposite of this pattern. Overinvolved carers made attributions of the patient's behavior to causes external to the patient and internal to themselves. Cortisol levels were associated with self-reports of strain and distress.

Are all psychological treatments for psychosis equal? The need for CBT in the treatment of psychosis and not for psychodynamic psychotherapy.

Paley and Shapiro conclude in their review (Paley & Shapiro, 2002) that there is clear evidence that cognitive-behaviour therapy (CBT) results in clear clinical benefits for people with schizophrenia. They argue that this research could be informed by the wider psychotherapy literature, specifically the 'equivalence paradox' and 'investigator allegiance', and that psychodynamic treatments for schizophrenia should be investigated and evaluated. We argue that their review of the literature is incomplete. We conclude that there is little evidence to support the 'equivalence paradox' generally, and where it is suggested, as in depression, this is most likely an artefact. In schizophrenia, there is consistent evidence that supportive psychotherapy performs poorly in treating hallucinations. We argue for improved methodology in carrying out randomized controlled trials, which would minimize bias, such as from 'investigator allegiance'. We consider evaluation of psychodynamic psychotherapy to demonstrate equivalence to CBT as a low priority and unlikely ever to be attempted. We consider the research and clinical priorities to be the further developments of CBT and family intervention methods, which could have significant benefits for sufferers of schizophrenia and their carers.

Economic impact of a specialist outreach team in residential and nursing home settings.

BACKGROUND: The results of a randomized controlled trial have indicated that a training and educational programme for staff in nursing or residential homes may result in reductions in levels of depression and levels of cognitive impairment for residents presenting with an active management problem. The training and educational intervention consisted of members of a hospital outreach team who presented a series of 1 hour seminars on topics which staff had indicated would improve their knowledge and skills. AIMS OF THE STUDY: The aim of this study was to present an exploratory analysis of the impact on costs associated with providing an old age psychiatry outreach team giving training and education for staff in nursing and residential homes. METHOD: For the economic study, a societal perspective was employed. Measures of resource use and costs to the health service, social and community services and the nursing and residential homes were analysed for 120 residents from 12 nursing or residential homes, as part of a randomized controlled trial to assess a training package provided in residential and nursing homes. Cost estimates were based on estimates from generalized estimated equations. To allow for clustering effects within homes, the unit of randomization was the home as opposed to the individual. To ensure models were correctly specified, several tests including the Ramsey RESET test were employed. RESULTS: There were no significant differences in the total cost per person in the homes that received the intervention and the control homes. This study has shown that the additional cost of providing the specialist outreach team was likely to be covered by reductions in the use of other resources such as GP visits to nursing and residential homes. Therefore, though the study had limitations, it appeared that improved care could be provided at little or no extra cost. IMPLICATIONS FOR HEALTH CARE PROVISION AND USE: The evidence presented suggests that the specialist outreach team was unlikely to add to the total cost of caring for residents in nursing and residential homes. This finding combined with the benefits in terms of lower levels of depression and cognitive impairment suggested that the intervention was good value for money. The intervention should be considered for use in other nursing and residential homes.
