Mental contamination in obsessive–compulsive disorder

It was recently proposed that feelings of contamination can arise in the absence of physical contact with a contaminant. Currently, there are limited data regarding this construct of ‘mental contamination’ although it is hypothesised to be relevant to obsessive compulsive disorder(OCD) where compulsive washing in response to contamination fear is a common presentation (Rachman,2006). This research examined the presence of mental contamination in OCD. Participants (N=177) with obsessive compulsive symptoms completed questionnaires to assess mental contamination, OCD symptoms and thought-action fusion (TAF). Findings indicated that 46% of participants experienced mental contamination, and severity was associated with severity of OCD symptoms and TAF. Mental contamination in the absence of contact contamination was reported by 10.2% of participants. Similar findings were reported in a sub-sample of participants who had received a formal diagnosis of OCD (N=54). These findings suggest that mental contamination is a distinct construct that overlaps with, but is separate from, contact contamination, and provide preliminary empirical support for the construct

Behavioural expressions, imagery and perfectionism

Background: High levels of multidimensional perfectionism may be dysfunctional in their own right and can also impact on the maintenance and treatment of Axis I psychiatric disorders. Aims: This paper sought to describe the behavioural expressions and imagery associated with perfectionism in a non-clinical sample. Method: Participants (n=59) completed a newly developed questionnaire to assess behavioural expressions of perfectionism, and an adapted interview to assess perfectionism-related intrusive mental images. Results: The study found that those high in perfectionism took longer to complete tasks, experienced more checking and safety behaviour whilst carrying out tasks, and had greater trouble actually completing tasks compared to those low in perfectionism. In addition, those with higher levels of perfectionism experienced intrusive mental imagery, which was more distressing, harder to dismiss, and had more impact on behaviour than those with lower levels of perfectionism. Conclusions: This research provides an initial exploration of the specific behaviours and intrusive mental imagery associated with perfectionism. The new behavioural measure of perfectionism could prove useful clinically in the assessment of change; however, these findings are preliminary and warrant replication in a clinical sample in order to examine their treatment implications

Abnormal and Normal Mental Contamination

Mental contamination is defined and the main features of the phenomenon are set out. In addition to the familiar form of abnormal mental contamination, as evident in psychological disorders, notably Obsessive-compulsive Disorder, the phenomenon of non-clinical mental contamination is common. The clinical form is distressing, uncontrollable, constant and dysfunctional. The normal phenomenon can be disturbing but it is usually dormant, evoked intermittently, transient, tolerable, manageable, not dysfunctional and psychologically fascinating. The cognitive theory of mental contamination encompasses the causes of mental contamination, its persistence, and individual vulnerability. The field would benefit greatly from additional work, such as that reported elsewhere in this Special Issue, to incorporate the unusual manifestations of visual contamination, morphing and self-contamination, and to account for the experience of mental contamination in nonclinical and other clinical manifestations

Given that many features of OCD are found in other diagnoses, the primary aim of this study was to determine whether mental contamination is specific to OCD or whether it is also associated with psychopathology found in other disorders. We hypothesised that, in addition to OCD symptoms, mental contamination would be associated with other psychopathology, in particular symptoms of depression, anxiety and eating disorders, and with transdiagnostic processes such as perfectionism. Methods 120 participants (82%) completed measures of psychological disorders and transdiagnostic processes. Results were analysed using Pearson's r correlations and a multiple regression analysis. Results Mental contamination was most strongly associated with symptoms of OCD but was also associated with eating disorder symptoms, depression and anxiety. It was also correlated with perfectionism, intolerance of uncertainty and fear of compassion. OCD, eating disorder symptoms, fear of compassion and low self-esteem were significant independent predictors of mental contamination. Conclusions Mental contamination is associated with a range of psychopathology but is most strongly associated with symptoms of OCD. Further research is warranted to advance treatment for mental contamination

The nature and assessment of mental contamination: A psychometric analysis

There has been a recent expansion of interest in the concept of mental contamination. Despite a growing number of experiments and interview-based studies of mental contamination, there is a need for questionnaire-based assessment measures, and for a further understanding of the degree to which mental contamination is related to other aspects of OCD symptomatology and/or to established cognitive constructs relevant to OCD. We assessed the psychometric properties of three new measures of mental contamination (the Vancouver Obsessional Compulsive Inventory – Mental Contamination Scale, the Contamination Sensitivity Scale, and the Contamination Thought-Action Fusion Scale) in participants diagnosed with OCD (n = 57), participants diagnosed with an anxiety disorder other than OCD (n = 24) and in undergraduate student controls (n = 410). For some of these analyses, our OCD sample was subdivided into those with contamination-related symptoms and concerns (n = 30) and those whose OCD excluded concerns related to contamination fear (n = 27). Results showed that the three new scales had excellent psychometric properties, including internal consistency, convergent and divergent validity, and discriminant validity. Further, the new measures accounted for significant unique variance in OCD symptoms over and above that accounted for by depression, anxiety, traditional contact-based contamination, and OCD beliefs. Results are discussed in terms of the clinical utility of the scales, and of the nature of contamination fears in OCD

Feasibility of low-intensity psychological interventions for emotional and behavioural difficulties in children and young people with genetic conditions: a case series

Background: Children with genetic conditions may experience significant mental health difficulties such as anxiety and challenging behaviour. However, understanding of the feasibility and effectiveness of psychological interventions for emotional and behavioural problems in the context of genetic conditions is limited. Low-intensity psychological interventions have demonstrated promise in paediatric populations and may be able to address their mental health difficulties. / Method: A case series design was used to assess the feasibility of low-intensity interventions for emotional and behavioural difficulties in children and young people with genetic conditions recruited from a mental health drop-in centre at a tertiary hospital. Participants received seven weekly sessions with a trained practitioner. The intervention was based on existing modular treatments and evidence-based self-help materials. Feasibility and treatment satisfaction were assessed, as well as measures of symptoms of anxiety and challenging behaviour, treatment goals, and quality of life, at baseline, during treatment, and six-month follow-up. / Results: Five participants received treatment for challenging behaviour, one for anxiety, and one for obsessive compulsive disorder. All participants completed treatment. Clinically significant change in the SDQ Total score was found in three participants. All participants demonstrated progress in goals and symptoms of emotional and behavioural difficulties over the course of treatment. / Conclusions: Low-intensity psychological interventions for emotional and behavioural difficulties in children and young people with genetic conditions is feasible, acceptable, and potentially beneficial. Further research is warranted to examine the effectiveness of the intervention and its use in clinical paediatric settings

Initial evidence review - Strategies for encouraging psychological and emotional resilience in response to loneliness 2019

It is now widely accepted that loneliness is influenced by a combination of psychological factors, including attitudes to participating in social interactions and mental health problems, as well as environmental factors such as living far from family and friends and life events and transitions such as bereavement and moving away from home. Despite increased recognition of the importance of individual-level processes and meanings that influence the experience of loneliness, there is a gap in our knowledge of how best to address the psychological factors that contribute to chronic loneliness. In this report, we aim to synthesise information from a range of sources in order to identify the psychological pathways to loneliness and relevant psychological barriers to accessing strategies which target social isolation. The report highlights promising interventions that have potential to target the psychological aspects of loneliness. It makes a series of recommendations to improve understanding and delivery of effective psychological interventions to address loneliness and how the interaction between such strategies and community-based interventions. We conducted an extensive scoping review of the academic literature, including online database searches and broader searches reviewing conference abstracts and reports from the Third Sector. We obtained expert opinions by speaking to relevant stakeholders including people with lived experiences of loneliness, charitable organisations working with people who are experiencing chronic loneliness, and those involved in developing and evaluating interventions to tackle loneliness. Much of the work focused on older adults but we also looked at interventions delivered across the age range. We report the findings from this work, including an overview of the wide range of psychological factors which might explain why some people who are chronically lonely struggle to engage with community strategies and other sources of support that are available. These factors include having mental health problems, personality characteristics and having unhelpful beliefs and behaviours related to social interactions. We recommend that interventions that target either the psychological or social aspects of loneliness should not be provided in isolation, and that multi-modal interventions are likely to be most successful. Further research evidence is needed to evaluate the feasibility, acceptability, effectiveness and cost-effectiveness of delivering psychological interventions in conjunction with community-based strategies. Social prescribing is a potential opportunity for the successful delivery of psycho-social interventions. For example, integration of psychological and community-based support could be promoted by including directories of psychological support in guides to community based resources, and by connecting social prescribing link workers with their local improving access to psychological therapies services. The social psychological approaches such as the Groups 4 Health model (Haslam et al., 2019; Haslam, Cruwys, Haslam, Dingle & Chang, 2016) show promise and potentially could bridge psychological and social understandings of loneliness. There is preliminary research evidence that interventions that address the psychological factors involved in loneliness can be successful, and there are various approaches to addressing these factors across the UK, although many initiatives have not yet been fully evaluated. The strongest research evidence was found for cognitive behavioural interventions, and there are some promising developments, including digital initiatives which are designed to change individuals’ thoughts and feelings about loneliness, that are worthy of further evaluation. We would also recommend that acceptance and commitment therapy is formally evaluated as an intervention for loneliness. We noted that the research base in this area is still underdeveloped and more work is needed to demonstrate which interventions are most accessible to people who are chronically lonely and can feasibly be delivered within NHS and community settings. Research into the potential adverse effects of psychological interventions, individual differences in responsiveness and the longer term impact on loneliness is also needed. It is likely that including measures of loneliness in evaluations of interventions for social anxiety and grief and in routine work with older adults in improving access to psychological therapies services would yield data that will contribute to the growing evidence base in this area. We hope that bringing together the research evidence and expert opinion in this report will increase awareness of the wide range of psychological factors implicated in loneliness and lead to further provision of psychological interventions for loneliness, in combination with community based support for social isolation

M.I.C.E-Mental Health Intervention for Children with Epilepsy: a randomised controlled, multi-centre clinical trial evaluating the clinical and cost-effectiveness of MATCH-ADTC in addition to usual care compared to usual care alone for children and young people with common mental health disorders and epilepsy-study protocol.

BACKGROUND: Mental health disorders in the context of long-term conditions in children and young people are currently overlooked and undertreated. Evidence-based psychological treatments for common childhood mental health disorders (anxiety, depression and disruptive behaviour disorders) have not been systematically evaluated in young people with epilepsy despite their high prevalence in this population. The aim of this multi-site randomised controlled trial is to determine the clinical and cost-effectiveness of adding a modular psychological intervention to usual care for the mental health disorders in comparison to assessment-enhanced usual care alone. METHODS: In total, 334 participants aged 3-18 years attending epilepsy services will be screened for mental health disorders with the Strengths and Difficulties Questionnaire (SDQ) and the diagnostic Development and Wellbeing Assessment (DAWBA). Those identified as having a mental health disorder and consenting to the trial will be randomised to either receive up to 22 sessions of the modular psychological intervention (MATCH-ADTC) delivered over the telephone over 6 months by non-mental health professionals in addition to usual care or to assessment-enhanced usual care alone. Outcomes will be measured at baseline, 6 months and 12 months post-randomisation. It is hypothesised that MATCH-ADTC plus usual care will be superior to assessment-enhanced usual care in improving emotional and behavioural symptoms. The primary outcome is the SDQ reported by parents at 6 months. Secondary outcomes include parent-reported mental health measures such as the Revised Children's Anxiety and Depression Scale, quality of life measures such as the Paediatric Quality of Life Inventory and physical health measures such as the Hague Seizure Severity Scale. Outcome assessors will be blinded to group assignment. Qualitative process evaluations and a health economic evaluation will also be completed. DISCUSSION: This trial aims to determine whether a systematic and integrated approach to the identification and treatment of mental health disorders in children and young people with epilepsy is clinically and cost-effective. The findings will contribute to policies and practice with regard to addressing mental health needs in children and young people with other long-term conditions.
