Looking at or through rose-tinted glasses? Imagery perspective and positive mood.

We can imagine looking at ourselves (observer perspective) or through our own eyes (field perspective). Cognitive and clinical theories suggest that compared to field perspective, observer perspective imagery reduces emotional intensity, for example, of trauma memories. Tests of causality are lacking and less is known about perspective and positive emotion. Using contrasting experimental manipulations, participants imagined 100 positive descriptions from either (1) a field perspective or (2) an observer perspective, or (3) thought about their verbal meaning. Affect was more positive after field than observer imagery and verbal conditions, with mood deterioration within the latter two. Findings are the first to demonstrate causality of imagery perspective on emotion. Further, the results demonstrate that imagining positive events from ones own perspective is critical to improving positive affect. Treatment implications include promoting field imagery to facilitate a more rose-tinted view of positive events.

Fishing for happiness: The effects of generating positive imagery on mood and behaviour

Experimental evidence using picture–word cues has shown that generating mental imagery has a causal impact on emotion, at least for images prompted by negative or benign stimuli. It remains unclear whether this finding extends to overtly positive stimuli and whether generating positive imagery can increase positive affect in people with dysphoria. Dysphoric participants were assigned to one of three conditions, and given instructions to generate mental images in response to picture–word cues which were either positive, negative or mixed (control) in valence. Results showed that the positive picture–word condition increased positive affect more than the control and negative conditions. Participants in the positive condition also demonstrated enhanced performance on a behavioural task compared to the two other conditions. Compared to participants in the negative condition, participants in the positive condition provided more positive responses on a homophone task administered after 24 h to assess the durability of effects. These findings suggest that a positive picture–word task used to evoke mental imagery leads to improvements in positive mood, with transfer to later performance. Understanding the mechanisms underlying mood change in dysphoria may hold implications for both theory and treatment development.

Psychological interventions for mental health disorders in children with chronic physical illness: a systematic review

Background Children with chronic physical illness are significantly more likely to develop common psychiatric symptoms than otherwise healthy children. These children therefore warrant effective integrated healthcare yet it is not established whether the known, effective, psychological treatments for symptoms of common childhood mental health disorders work in children with chronic physical illness. Methods EMBASE, MEDLINE, PsycINFO and CINAHL databases were searched with predefined terms relating to evidence-based psychological interventions for psychiatric symptoms in children with chronic physical illness. We included all studies (randomised and non-randomised designs) investigating interventions aimed primarily at treating common psychiatric symptoms in children with a chronic physical illness in the review. Two reviewers independently assessed the relevance of abstracts identified, extracted data and undertook quality analysis. Results Ten studies (209 children, including 70 in control groups) met the criteria for inclusion in the review. All studies demonstrated some positive outcomes of cognitive behavioural therapy for the treatment of psychiatric symptoms in children with chronic physical illness. Only two randomised controlled trials, both investigating interventions for symptoms of depression, were found. Conclusions There is preliminary evidence that cognitive behavioural therapy has positive effects in the treatment of symptoms of depression and anxiety in children with chronic physical illness. However, the current evidence base is weak and fully powered randomised controlled trials are needed to establish the efficacy of psychological treatments in this vulnerable population.

Biased interpretation in perfectionism and its modification

Perfectionism is a transdiagnostic construct associated with a range of diagnoses, including depression, eating disorders and obsessive compulsive disorder. Treatments that directly target perfectionist cognitions have been shown to successfully reduce associated pathologies. However, the way in which they do this is not clear. We set out to assess the role of one candidate mechanism of action, namely the cognitive process of interpretation of ambiguity. In one experiment we looked for associations between biased interpretation and perfectionism. In a second, we manipulated interpretations, thereby providing a strong test of their aetiological significance. Results from the first experiment confirmed the presence of biased interpretation in perfectionism and demonstrated that these are highly specific to perfection relevant information, rather than reflecting general negativity. The second experiment succeeded in manipulating these perfection relevant interpretations and demonstrated that one consequence of doing so is a change in perfectionist behaviour. Together, these data experimentally demonstrate that biased interpretation of perfection relevant ambiguity contributes to the maintenance of perfectionism, but that it is also possible to reverse this. Clinical implications include the identification of one likely mechanism of therapeutic change within existing treatments, as well as identification of an appropriate evidence-based focus for future treatment development. Targeting underlying functional mechanisms, such as biased interpretation, has the potential to offer transdiagnostic benefits.

Oxford guide to the treatment of mental contamination

PART 1: PHENOMENA OF CONTAMINATION FEARS PART 2: COGNITIVE-BEHAVIOURAL TREATMENT OF MENTAL CONTAMINATION

Advances in the Cognitive Behavioural Treatment of Obsessive Compulsive Disorder

The aim of this paper is to highlight key advances in the cognitive-behavioural treatment of obsessive compulsive disorder over the course of Professor Lars Göran Östs illustrious career. The paper will focus on three specific areas of interest: the treatment of obsessions, compulsive checking, and the fear of contamination. It will also highlight recent advances concerning the broader need to ensure that treatment is acceptable. An increase in acceptability could result in improvements in completion rates so that more patients benefit from the recent improvements in the science and therapy for this disabling disorder.

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.

The effectiveness of telephone-delivered psychological therapies for depression and anxiety: A systematic review.

Objectives The telephone is increasingly used to deliver psychological therapies for common mental health problems. This review addressed the following question: are evidence-based psychological therapies for adults with depression and/or anxiety effective in reducing psychological symptoms when delivered over the telephone? Method A systematic search for articles published over a 25-year period (January 1991–May 2016) was performed using the databases PsycINFO, PubMed and Web of Science. Citation searches, manual searches of bibliographies of relevant papers, and hand searches of key journals were also conducted. The quality of the studies included for review was assessed using the Effective Public Health Practice Project Quality Assessment Tool. Results Fourteen studies met inclusion criteria for the review. Ten reported findings from telephone treatment for depression and four for anxiety. Nine studies used randomised controlled designs, two used quasi-experimental designs and three used uncontrolled designs. Thirteen studies reported reductions in symptoms of depression or anxiety. Cohen’s d ranged from 0.25–1.98 (median = 0.61) for controlled studies and from 1.13–1.90 (median = 1.26) for uncontrolled studies. Only four studies reported clinically significant change. Conclusions The findings indicate that telephone-delivered interventions show promise in reducing symptoms of depression and anxiety. Further research is required to establish the types of interventions that are most effective and the characteristics of clients who find them beneficial.

Medically unexplained visual loss in children and young people: an observational single site study of incidence and outcomes

PurposeTo determine the incidence of medically unexplained visual loss (MUVL) in children in an open access children’s eye casualty.Patients and methodsWe collated demographic and clinical data of consecutive patients younger than 16 years who presented to the children’s eye casualty at Moorfields Eye Hospital over a 12-month period and were diagnosed with MUVL or suspected MUVL. We reviewed the clinical records at least 3 months after initial presentation. We calculated the incidence using the number of ‘new patient’ attendances over the same period as denominator (n=2397). We used descriptive analysis. Main outcome measures: number of patients diagnosed with MUVL, proportion of patients with a history of or present psychological problems, recovery rate, and improvement in visual acuity.ResultsWe identified 85 cases of MUVL (54 females; median age: 9 years (IQR 7–12)). The median duration of follow-up was 1.2 months (IQR 0–4.3). The estimated annual incidence was 3.5% (95% confidence interval 2.9–4.4%). Thirty-three per cent of children had a history of psychiatric disorders, reported a stressful life event, or showed signs of psychiatric disorder at the time of first presentation. The recovery rate was 25%. Median improvement in best-corrected visual acuity from presentation to last appointment was 0.22 (IQR 0.06–0.43) logMAR.ConclusionThe incidence of MUVL is higher and the rate of resolution lower than previously reported. MUVL may be associated with mental health problems. We recommend screening for psychological problems to facilitate access to psychological treatment.

Cognitive behaviour treatment of co-occurring depression and generalised anxiety in routine clinical practice

Background Anxiety and depression are closely associated. However, they are typically treated separately and there is a dearth of information on tackling them together. Aims The study’s purpose was to establish how best to treat co-occurring anxiety and depression in a routine clinical service—specifically, to compare cognitive behaviour therapy (CBT) focusing only on depression (CBT-D) to a broader CBT focusing on both depression and anxiety (CBT-DA). Method Case notes of 69 patients with equally severe clinical levels of depression and anxiety seen in a routine clinical service were randomly selected to review from a pool of 990 patients. The mean age was 44.61 years (SD = 12.97). 65% of the sample were female and 88% reported their ethnicity white. The content of electronic records reporting techniques used and scores on a measure of depression (The Patient Health Questionnaire) and anxiety (The Generalized Anxiety Disorder Assessment) were reviewed to categorise therapy as CBT-D or CBT-DA. Results Results indicated significant overall improvement with CBT; 70% and 77% of the sample met criteria for reliable improvement on The Patient Health Questionnaire and The Generalized Anxiety Disorder Assessment respectively. Fewer patients who received CBT-DA met The Generalized Anxiety Disorder Assessment recovery criteria at the end of treatment than those who received CBT-D. Mean post treatment PHQ-9 and GAD-7 scores remained above threshold for those receiving CBT_DA but not those receiving CBT-D. There was no evidence suggesting CBT-DA was superior to CBT-D. Conclusions In patients with equally severe clinical levels of depression and anxiety, a broader treatment addressing both anxiety and depression does not appear to be associated with improved outcomes compared to treatment focused on depression.
