Cognitive model of caregiving in psychosis

BACKGROUND There is a long history of research into the attributes of carers of people with psychosis, but few interventions target their distress or their difficulties. AIMS To describe an empirically based model of the relationships of those caring for people with psychosis to inform clinical and theoretical advances. METHOD We developed a model of informal carer relationships in psychosis, based on an integration of the literature elaborating the concept of expressed emotion. The model accounts for divergent outcomes of three relationship types: positive, overinvolved and critical/hostile relationships. RESULTS Good evidence supports a number of hypotheses concerning the origin and maintenance of these relationship outcomes, which relate to specific differences in carer attributions, illness perceptions, coping behaviour, social support, distress, depression and low self-esteem predicted by our model. We propose that interventions aimed at modifying the specific maintenance factors involved in the different styles of relationships will optimise therapeutic change both for service users with psychosis and for their carers. CONCLUSIONS Family work in psychosis, which improves relationships through problem-solving, reduces service user relapse. It is now time to consider theory-based interventions focused on improving carer outcomes.

Family interventions in early psychosis: specificity and effectiveness

The first episode of psychosis frequently occurs during adolescence and early adulthood, and is associated with high levels of trauma, affective disturbance and suicide. The social networks of service users often decrease significantly following the first onset, although many will remain in close contact with some family members particularly during the early phases. However, the negative impact of psychosis on families and their relationship with the identified service user are well documented. Family intervention is a recommended and evidence-based treatment in later psychosis. In this paper, we review the literature on family interventions in early psychosis in the context of new evidence for its efficacy and its routine incorporation in early intervention services for psychosis.

Implementing the NICE guideline for schizophrenia recommendations for psychological therapies: a qualitative analysis of the attitudes of CMHT staff

OBJECTIVES Despite national guidelines recommending cognitive-behavioural therapy (CBT) and family intervention (FI) in the treatment of schizophrenia, levels of implementation in routine care remain low. The present study investigates attitudinal factors amongst community mental health team (CMHT) staff affecting guideline implementation. DESIGN CMHTs were audited to measure the capacity and delivery of CBT and FI, and semi-structured interviews were conducted with staff from the teams. Methods. Four CMHTs were audited, and five care coordinators from each team were interviewed. A purposive approach to sampling was used to represent the range of professional training of care coordinating staff. Data were analysed using thematic content analysis. RESULTS Positive views towards guidelines were evident, although tempered by specific implementation issues. Employing simple psychological interventions and approaches as part of the care coordinating role also emerged as highly valued by staff. Severe workload, time pressure and the need for specialist staff were crucial barriers to implementation. Pessimistic views of recovery for clients with psychosis were also apparent and may affect implementation. CONCLUSIONS Staff attitudes and knowledge are an important area of research when examining guideline implementation and require further study. Key themes that have emerged could inform future training agendas and should be considered when developing guideline implementation strategies for the updated 2009 guidelines.

Discrepant illness perceptions, affect and expressed emotion in people with psychosis and their carers

BackgroundIllness perception, a measure of illness representations developed from physical medicine, has recently been applied to psychosis. We investigated how illness perceptions relate to affect and expressed emotion (EE) in carer-patient dyads, particularly if their perceptions differed.MethodWe interviewed 82 carer-patient dyads, after a relapse of psychosis. Carers were assessed for illness perceptions, distress, self-esteem and EE; patients for illness perceptions, depression, anxiety and self-esteem, in a cross sectional study.ResultsCarers were more pessimistic than patients about illness persistence and consequences, and carers with low mood were particularly pessimistic about persistence and controllability. Discrepant views about illness consequences were related to greater anxiety, depression, and lower self-esteem in patients, while discrepant views on controllability were associated with greater distress, depression, and lower self-esteem in carers. Illness perceptions did not relate directly to EE.ConclusionsIn this sample, meta-cognitive carer representations of illness in psychosis are related to negative affective reactions in carers, but not to EE. Resolving discrepant illness perceptions between carers and patients might provide a way of improving family reactions to the health threat of psychosis.

Mental and physical illness in caregivers: results from an English national survey sample

BACKGROUND Caregivers make a significant and growing contribution to the social and medical care of people with long-standing disorders. The effective provision of this care is dependent on their own continuing health. AIMS To investigate the relationship between weekly time spent caregiving and psychiatric and physical morbidity in a representative sample of the population of England. METHOD Primary outcome measures were obtained from the Adult Psychiatric Morbidity Survey 2007. Self-report measures of mental and physical health were used, along with total symptom scores for common mental disorder derived from the Clinical Interview Schedule-Revised. RESULTS In total, 25% (n = 1883) of the sample identified themselves as caregivers. They had poorer mental health and higher psychiatric symptom scores than non-caregivers. There was an observable decline in mental health above 10 h per week. A twofold increase in psychiatric symptom scores in the clinical range was recorded in those providing care for more than 20 h per week. In adjusted analyses, there was no excess of physical disorders in caregivers. CONCLUSIONS We found strong evidence that caregiving affects the mental health of caregivers. Distress frequently reaches clinical thresholds, particularly in those providing most care. Strategies for maintaining the mental health of caregivers are needed, particularly as demographic changes are set to increase involvement in caregiving roles.

Effective elements of cognitive behaviour therapy for psychosis: results of a novel type of subgroup analysis based on principal stratification

Background Meta-analyses show that cognitive behaviour therapy for psychosis (CBT-P) improves distressing positive symptoms. However, it is a complex intervention involving a range of techniques. No previous study has assessed the delivery of the different elements of treatment and their effect on outcome. Our aim was to assess the differential effect of type of treatment delivered on the effectiveness of CBT-P, using novel statistical methodology. Method The Psychological Prevention of Relapse in Psychosis (PRP) trial was a multi-centre randomized controlled trial (RCT) that compared CBT-P with treatment as usual (TAU). Therapy was manualized, and detailed evaluations of therapy delivery and client engagement were made. Follow-up assessments were made at 12 and 24 months. In a planned analysis, we applied principal stratification (involving structural equation modelling with finite mixtures) to estimate intention-to-treat (ITT) effects for subgroups of participants, defined by qualitative and quantitative differences in receipt of therapy, while maintaining the constraints of randomization. Results Consistent delivery of full therapy, including specific cognitive and behavioural techniques, was associated with clinically and statistically significant increases in months in remission, and decreases in psychotic and affective symptoms. Delivery of partial therapy involving engagement and assessment was not effective. Conclusions Our analyses suggest that CBT-P is of significant benefit on multiple outcomes to patients able to engage in the full range of therapy procedures. The novel statistical methods illustrated in this report have general application to the evaluation of heterogeneity in the effects of treatment.

Caregiving in first‐episode psychosis: social characteristics associated with perceived ‘burden’ and associations with compulsory treatment

High incidence of psychosis and compulsory treatment within black and minority ethnic (BME) groups in the UK remain a concern. Psychosis has an impact on families and family involvement is important in predicting compulsory treatment. We therefore aimed to report the levels and predictors of caregiver burden in first‐episode psychosis, in white British, and BME groups of carers, and investigate their relevance to compulsory treatment.

Patient perceptions of caregiver criticism in psychosis: links with patient and caregiver functioning

Expressed emotion (EE) has been described as a measure of caregivers’ appraisals of the quality of their relationship with patients. However, far less is known about how the perception of their caregivers by patients with psychosis is shaped by caregivers’ EE, and nothing about the clinical correlates of perceived EE. The current study examines the association of patient ratings of carer criticism with patient and carer characteristics. Patient ratings of carer criticism were also compared with the ratings of the carer derived from the Camberwell Family Interview. Sixty-seven patient-carer dyads participated in the cross-sectional study. Perceived carer criticism was associated with general psychopathology in patients, but not with overall levels of positive or negative symptoms of psychosis. Patients with lower levels of social functioning, higher levels of negative affect, and negative schematic beliefs about other people, tended to perceive greater criticism. Perceptions of carer criticism were associated with Camberwell Family Interview ratings of carer criticism, hostility, and high EE independently of affect, and poorer functioning. High EE was a significant predictor of perceived carer criticism. This study supports the validity of using feedback from patients to assess the emotional climate of the family environment.

Opportunities and challenges in Improving Access to Psychological Therapies for people with Severe Mental Illness (IAPT-SMI): Evaluating the first operational year of the South London and Maudsley (SLaM) demonstration site for psychosis

Despite its demonstrated clinical and economic effectiveness, access to Cognitive Behavioural Therapy for psychosis (CBTp) in routine practice remains low. The UK National Health Service (NHS England) Improving Access to Psychological Therapies for people with Severe Mental Illness (IAPT-SMI) initiative aims to address this problem. We report 14-month outcomes for our psychosis demonstration site. Primary and secondary care and self-referrals were screened to check the suitability of the service for the person. Psychotic symptoms, distress, service use, functioning and satisfaction were measured before and after therapy, by trained assessors. User-defined wellbeing and goal-attainment were rated sessionally. Access to CBTp increased almost threefold (2011/12 accepted referrals/year n = 106; 2012/13, n = 300). The IAPT-SMI assessment protocol proved feasible and acceptable to service users, with paired primary outcomes for 97% of closed cases. Therapy completion (≥5 sessions) was high (83%) irrespective of ethnicity, age and gender. Preliminary pre-post outcomes showed clinical improvement and reduced service use, with medium/high effect sizes. User-rated satisfaction was high. We conclude that individual psychological interventions for people with psychosis can be successfully delivered in routine services using an IAPT approach. High completion rates for paired outcomes demonstrate good user experience, clinical improvement, and potential future cost savings.

Nightmares in Patients with Psychosis: The Relation with Sleep, Psychotic, Affective, and Cognitive Symptoms

Objective: To examine the prevalence of nightmares in people with psychosis and to describe the link between nightmares and sleep quality, psychotic, affective, and cognitive symptoms. Methods: Forty participants with psychotic symptoms completed an assessment of nightmares, sleep quality, positive symptoms of psychosis, affect, posttraumatic stress, social functioning, and working memory. Results: Among the patients, 55% reported weekly distressing nightmares. Experience of more frequent nightmares was related to poorer sleep quality and sleep efficiency. More distressing nightmares were positively associated with greater delusional severity, depression, anxiety, stress, and difficulties with working memory. Conclusions: Nightmares might be common in those with psychosis and are associated with increased day- and nighttime impairment. Future research should investigate treatments for nightmares, for people presenting with psychotic symptoms.
