Cognitive behavioural therapy from the perspective of clients with mild intellectual disabilities: a qualitative investigation of process issues.

BACKGROUND: Clinicians working with clients who have mild intellectual disabilities (IDs) have shown growing enthusiasm for using a cognitive behavioural approach, amid increasing evidence of good treatment outcomes for this client group. However, very little is known about the views and experiences of clients with IDs who have undergone cognitive behavioural therapy. This study aims to explore the perspective of these clients. METHODS: Fifteen participants with borderline to mild IDs and problems of anxiety, depression and anger were interviewed regarding their experience of cognitive behavioural therapy (CBT). Two semi-structured interviews were carried out in the first phase of therapy between session four and session nine. An interpretive phenomenological approach was taken to seek out themes from participants' own personal accounts. RESULTS: Participants valued the opportunity to talk about problems with their therapist and benefitted from therapeutic relationships characterised by warmth, empathy and validation. Participants identified areas of positive change; however, many thought that this may be short lived or not maintained beyond discharge. CONCLUSIONS: The supportive aspects of therapeutic relationships were particularly important to participants undergoing CBT. The clinical implications are considered.

Cognitive behavioural therapy: from face to face interaction to a broader contextual understanding of change.

Cognitive behavioural therapy (CBT) is increasingly used to address the emotional and interpersonal problems of people with ID. There is a limited but promising evidence base supporting this activity. However, these individuals face real and continuing challenges in their lives that have implications for their self and interpersonal perceptions. These adversities have implications for the adaptation of CBT. First, it may mean that characteristically negative perceptions may be more common and may be the result of a complex interaction with a truly aversive environment and should not simply be considered as cognitive distortions. Secondly, clients may have limited control over their everyday lives, with limited opportunity to negotiate change with their informal and formal sources of support. This review suggests that it is important to consider the interpersonal context of therapy both to ensure effective work within sessions and to enable real change in clients' everyday lives. The review draws upon Vygotsky's theory of the zone of proximal development and ecological models of change to consider the challenges of establishing collaborative relationships and the potential to use CBT within a broad psychosocial model. The aim is to offer a helpful framework for practitioners and to identify directions for future research.

Improving psychological adjustment following a first episode of psychosis: a randomised controlled trial of cognitive therapy to reduce post psychotic trauma symptoms.

There are few evaluated psychological interventions or theoretical approaches which are specifically aimed at reducing problems related to adjustment and adaptation following a first episode of psychosis. The present study tests the efficacy of a form of CBT (Cognitive Recovery Intervention; CRI) in reducing trauma, depression and low self esteem following a first episode of psychosis, in a single-blind randomised controlled trial. A total of 66 patients who had recently experienced a first episode of psychosis were randomly assigned to CRI or treatment as usual (TAU) and followed up at 6 and 12 months. People receiving CRI tended to have lower levels of post-intervention trauma symptoms and demonstrated greater improvement than those receiving TAU alone. This was especially the case at 6 months for those with high pre-treatment levels of trauma. There was, however, no advantage for the CRI group with regards to reduced depression or improved self esteem. In conclusion, CRI appears to be an effective intervention to help young people adapt to the traumatic aspects of a first episode of psychosis although further evaluation in a larger study is warranted.

Phenomenological evidence for two types of paranoia.

OBJECTIVE: Two types of paranoia have been identified, namely persecution (or 'Poor Me') paranoia, and punishment (or 'Bad Me') paranoia. This research tests predicted differences in phenomenology--specifically, in person evaluative beliefs, self-esteem, depression, anxiety, and anger. METHOD: Fifty-three people with current paranoid beliefs were classified as Poor Me, Bad Me, or neither (classification was reliable). Key dependent variables were measured. RESULTS: All predictions were supported, except the one relating to anger, where the two groups did not differ. The Bad Me group had lower self-esteem, more negative self-evaluative thinking, lower negative evaluations about others, higher depression and anxiety. Importantly, the differences in self-esteem and self-evaluations were not fully accounted for by differences in depression. CONCLUSION: Data support the presence of two distinct topographies of paranoia. Future research is needed to explore the theory further and examine clinical implications.

What do psychotic experiences mean for young men? A qualitative investigation.

This study is of a grounded theory analysis of the transcripts of young men talking about their experience of psychosis. Six young men were interviewed twice during the critical period of 3-5 years following their first psychotic episode. The young men were asked to reflect on themselves and their lives before, during, and after having psychotic experiences. The transcripts were considered to have a phenomenological status, in that they represented the participants' perspectives on their experiences. Four themes emerged that were common to all the accounts: experience of psychosis, immediate expression of psychotic experiences, personal and interpersonal changes, and personal explanations. These themes are explored in detail, and their links with existing research and clinical implications are considered.

Contingent reinforcement or defending the self? A review of evolving models of aggression in people with mild learning disabilities.

This paper examines the changing approaches to working with people with a moderate to mild learning disability, who are frequently aggressive. Long-held assumptions about the lack of inter-personal understanding and impulsiveness continue to play a central role in clinical assessment and intervention for this group. Yet, there is a lack of controlled studies indicating the influence of such factors in frequent aggression. The dominant behavioural tradition has long encouraged such assumptions, but has focused on people with more severe disabilities where such assumptions are arguably more appropriate. The current review of the literature shows a clear evolution away from a strict behavioural approach towards cognitive-behavioural therapy (CBT) approaches that take account of the heterogeneous psychosocial causes of aggression. We find support for CBT in the child-development literature, which examines inter-personal difficulties from an information-processing perspective. Finally, we argue that much of the literature implicitly utilizes the concept of self, and we suggest that this should be made explicit in a reformulated theory of the 'person', incorporating the self concept and embedding individual cognitive processes and behaviour in a social context.

An exploration of evolved mental mechanisms for dominant and subordinate behaviour in relation to auditory hallucinations in schizophrenia and critical thoughts in depression.

BACKGROUND: Mental mechanisms have evolved to enable animals (and humans) to be able to function in various social roles. It is suggested that the nature and functions of the mental mechanisms that enable animals to act as a hostile-dominant or threatened-subordinate can be distinguished. It is further suggested these can be internally activated and 'play off' against each other, such that a person 'attacks' themselves and then responds to their own internal attacks with subordinate defences. Hence, a depressed person can submit, feel defeated, belittled, beaten down, or want to run away (escape) from their own self-attacking thoughts, while psychotic voice hearers can feel similarly to their hostile voices. Such internal interactions may relate to depression in both psychotic voice hearers and depressed people. METHOD: A group of 66 voice hearers with a diagnosis of schizophrenia and 50 depressed patients were compared on a series of self-report questionnaires measuring the power of hostile self-directed thoughts/voices and the activation of defensive responses, especially fight/flight. RESULTS: We present evidence that schizophrenic, malevolent voice hearers and self-critical depressed people experience their hostile, internally generated voices/thoughts as powerful, dominating and controlling (i.e. have typical characteristics of a hostile dominant). Moreover, these voices/thoughts activate evolved subordinate defences such as fight/flight and these are associated with depression in both depression and schizophrenia. CONCLUSION: Conceptualizing aspects of depressed and psychotic thinking as relating to evolved mental mechanisms, which are role serving, but can internally play off against each other, may open new ways of investigating certain aspects of severe pathologies.

Why does schizophrenia develop at late adolescence?

Schizophrenia is one of the most researched, yet still one of the least understood, of the mental disorders. One key area that remains comparatively neglected is the fact that schizophrenia typically develops at late adolescence. In common with people with psychotic disorders, around 25% of normal teenagers also report finding adolescence very distressing, and a substantial empirical literature shows that certain characteristics typical of adolescence such as conflicted family relationships, grandiosity, egocentrism, and magical ideation bear a distinct resemblance to phenomena seen in psychotic disorders. Indeed, such phenomena, as might be judged prodromal or symptomatic in first-onset schizophrenia, have been shown to be remarkably common in normal adolescents, generally in about 50% of samples. Furthermore, prodromal-like signs in normal adolescents appear to be functionally linked to psychological development. For most adolescents, such phenomena pass with successful psychological development. It is proposed that psychosis in late adolescence is a consequence of severe disruption in this normally difficult psychological maturational process in vulnerable individuals, and explanations are offered as to why and how this comes about. It is suggested that problems either in reaching psychological maturity with regard to parents or in bonding to peers or both, may lead to crucial self-construction difficulties, and that psychosis emerges out of such "blocked adolescence." This approach proposes therapeutic interventions that enable professional services to side with both parents and clients simultaneously, and is normalizing and stigma-free.

Cognitive approach to depression and suicidal thinking in psychosis. 1. Ontogeny of post-psychotic depression.

BACKGROUND: Depression in schizophrenia is a rather neglected field of study, perhaps because of its confused nosological status. Three course patterns of depression in schizophrenia, including post-psychotic depression (PPD), are proposed. AIMS: We chart the ontogeny of depression and psychotic symptoms from the acute psychotic episode over a 12-month period and test the validity of the proposed course patterns. METHOD: One hundred and five patients with ICD-10 schizophrenia were followed up on five occasions over 12 months following the acute episode, taking measures of depression, positive symptoms, negative symptoms, neuroleptic exposure and side-effects. RESULTS: Depression accompanied acute psychosis in 70% of cases and remitted in line with the psychosis; 36% developed PPD without a concomitant increase in psychotic symptoms. CONCLUSIONS: The results provided support for the validity of two of the three course patterns of depression in schizophrenia, including PPD. Post-psychotic depression occurs de novo without concomitant change in positive or negative symptoms.

Cognitive approach to depression and suicidal thinking in psychosis. 2. Testing the validity of a social ranking model.

BACKGROUND: In paper I we reported that depression in the acute stage remitted in line with the psychosis and that 36% of patients developed post-psychotic depression (PPD). AIMS: We apply our cognitive framework to PPD and chart the appraisal of self and psychosis and their link with the later emergence of PPD. METHOD: Patients with ICD-10 schizophrenia (n=105) were followed up over 12 months following the acute episode, taking measures of depression, working self-concept, cognitive vulnerability, insight and appraisals of psychosis. RESULTS: Before developing PPD, these patients felt greater loss, humiliation and entrapment by their illness than those who relapsed or did not become depressed, and were more likely to see their future selves in 'lower status' roles. Upon becoming depressed, participants developed greater insight, lower self-esteem and a worsening of their appraisals of psychosis. CONCLUSIONS: Depression in psychosis arises from the individual's appraisal of psychosis and its implications for his/her perceived social identity, position and 'group fit'. Patients developing PPD feel forced to accept a subordinate role without opportunity for escape. Implications for treatment are discussed.

The power and omnipotence of voices: subordination and entrapment by voices and significant others.

BACKGROUND: Cognitive therapy for psychotic symptoms often embraces self-evaluative beliefs (e.g. self-worth) but whether and how such beliefs are related to delusions remains uncertain. In previous research we demonstrated that distress arising from voices was linked to beliefs about voices and not voice content alone. In this study we examine whether the relationship with the voice is a paradigm of social relationships in general, using a new framework of social cognition, 'ranking' theory. METHOD: In a sample of 59 voice hearers, measures of power and social rank difference between voice and voice hearer are taken in addition to parallel measures of power and rank in wider social relationships. RESULTS: As predicted, subordination to voices was closely linked to subordination and marginalization in other social relationships. This was not the result of a mood-linked appraisal. Distress arising from voices was linked not to voice characteristics but social and interpersonal cognition. CONCLUSION: This study suggests that the power imbalance between the individual and his persecutor(s) may have origins in an appraisal by the individual of his social rank and sense of group identification and belonging. The results also raise the possibility that the appraisal of voice frequency and volume are the result of the appraisal of voices' rank and power. Theoretical and novel treatment implications are discussed.

Psychometric properties of the Hospital Anxiety and Depression Scale with a population of members of a depression self-help group.

This paper reports the psychometric properties of the Hospital Anxiety and Depression Scale when used with 341 members of a self-help group for people with depression. We report internal reliability and factor structure for the complete data set and factor structure for groups split by gender, previous hospitalization for depression and current use of medication for depression. In each instance the factor structure reflects the intended depression and anxiety subscales. We comment on the usefulness of the HADS in studies of cognitive processes in depression and anxiety.

Facing stress and conflict: a comparison of the predicted responses and self-concepts of aggressive and non-aggressive people with intellectual disability.

The present research consisted of two studies. A total of 44 participants were involved in the first study: 22 individuals with problems of aggression (Ag) and 22 non-aggressive (NAg) individuals. A sentence completion test was used to explore whether there were differences between the two groups' predicted coping responses in stressful situations. While the Ag group provided most aggressive responses, the NAg participants were more assertive. However, gender differences also emerged, with women proving to be less aggressive. A high number of passive answers were given across all the groups, suggesting that background experience could have influenced the participants' sense of efficacy in stressful situations. In the second study, a subsample of the participants were interviewed. The aim was to explore whether particular background experience coloured their perceptions of self and others, in situations of conflict. While nine out of the 10 Ag participants described incidents where they felt treated in a derogatory manner which could be linked to their disability, only two out of the nine NAg participants felt slighted in this fashion. Hence, a vulnerable sense of self could contribute to greater sensitivity in interpersonal situations, increasing the likelihood of an aggressive response. The clinical relevance of this work is discussed, alongside the possibilities for future research in this area.

Early attachment experience and recovery from psychosis.

OBJECTIVES: Two studies were carried out to investigate the relationship between coping styles and co-morbid depression in people adjusting to the onset of psychosis. Evaluative thinking and early attachment experiences were also examined. METHODS AND DESIGN: In Study 1, a 39-item Recovery Style Questionnaire (RSQ) was developed to measure recovery style in people with psychosis, based on McGlashan, Levy & Carpenter's (1975) interview measure of recovery style. Fifty-six participants completed both the RSQ and McGlashan's interview-based measure. Study 2 explores the relationship between these styles of recovery, depression and early childhood attachment experiences. Thirty-six people participated. RESULTS: The RSQ was both reliable and correlated highly with McGlashan's interview-based measure. We found that the RSQ, in keeping with the interview-based measure, was bimodally distributed, thus supporting McGlashan's contention that they define two distinct recovery styles termed 'integration' and 'sealing over'. As predicted, 88 per cent of the 'sealers' were moderately to severely depressed compared to 52 per cent of the 'integrators' who were mildly depressed with no members of the 'integration' group experiencing moderate to severe depression (p < .0003). Patients who employed the sealing over recovery style also made significantly more negative self-evaluations than did patients in the integration group and also perceived their parents to be significantly less caring than those in the integration group. CONCLUSIONS: These findings are explained in terms of a multi-axial model incorporating personality structure and development as well as mental disorder. It is suggested that those individuals with a poorly developed sense of self defend against the threat of psychosis using denial. Clinical implications are discussed and more research is suggested to further investigate the links between evaluative and inferential thinking in co-morbid depression, and how such thinking relates to early childhood experience.

Care staff responses to people with learning disabilities and challenging behaviour: a cognitive-emotional analysis.

This study explores the application of Weiner's cognitive-emotional model of helping behaviour to care staff responses to challenging behaviour of people with learning disabilities. Participants were 20 residential care staff who worked with people with challenging behaviour and 20 who did not. Six examples of challenging behaviour were presented, and for each behaviour participants were asked to give a probable cause, rate attributions of stability, internality, globality and controllability for their cause, their optimism for change of the behaviour, their evaluation of the behaviour and a person showing the behaviour, their emotional response to the behaviour and their willingness to put extra effort in to helping change the behaviour. Data were analysed using correlation and regression methods. Carers working with people with challenging behaviour were more likely to evaluate the person more positively and report they would be more likely to offer extra effort in helping. A path analysis showed that helping behaviour was best predicted by optimism, which was best predicted by negative emotion which was best predicted by the attribution of controllability. We conclude that attributions and emotions reported by carers in response to challenging behaviour are consistent with Weiner's cognitive-emotional model of helping behaviour. Formulating carer behaviour using such models offers the possibility of using cognitive-behavioural methods in working with staff beliefs, emotions and behaviour in response to challenging behaviour.

Selective processing of concern-related information in depression.

OBJECTIVES: The major question examined in this paper is whether selective attentional and interpretative processing of emotional information occurs in depression, and if so, whether it depends on a close match between the material used and current concerns. DESIGN: Twenty-four depressed patients and the same number of matched controls were tested using two selective processing tasks (described below), and their performance related to self-reported sociotropic and autonomy-related concerns. METHODS: Colour-naming interference and interpretation of ambiguous situations were assessed using material judged relevant to each of the Sociotropy-autonomy Scales. RESULTS: Depression was associated with a general interference effect for all negative concern words, and more negative interpretations of ambiguous situations, while controls showed a converse bias in favour of all positive interpretations. There was no convincing evidence that this negative processing bias was proportional to the match between material and self-reported sociotropic or autonomous concerns. CONCLUSIONS: Depressed patients showed evidence of cognitive biases favouring all negative self-related information, on both attentional and interpretative tasks. We suggest that such effects in depression may occur only under conditions allowing the elaborative processing of negative material related to oneself.

Cognitive therapy for punishment paranoia: a single case experiment.

There is growing agreement that at least certain kinds of delusions defend against negative self-evaluation, and in consequence that cognitive therapy for delusions needs to address issues of self-evaluation more explicitly. However, in practice it can be difficult to enable clients to see the connection between delusions and self-esteem. The present single-case study exemplifies the conceptual and practical application of cognitive therapy for individuals who are both paranoid and have strong negative self-evaluative beliefs. A multiple-baseline approach is used, whereby one man's negative self-evaluative belief and two paranoid delusions are challenged sequentially. Conviction in two of the three beliefs changes at the point of intervention; conviction in the third changes prior to intervention. We discuss the details of the case, as well as the wider implications for cognitive approaches to delusions.
