Imaginator: a Pilot of Brief Functional Imagery Training for Self-harm

Study Overview
=================
Brief Summary
-----------------
Self-harm has substantial personal impacts as well as costs on the National Health Service (NHS). Around 13-17% of young people report experiences of self-harm. In Cambridgeshire, this is a significant issue with the number of admissions to hospital for self-harm in young people being higher than the United Kingdom (UK) average. Treating underlying mental illness can lead to a reduction in self-harm, but these are long interventions for complex disorders and many people who self-harm are not under treatment for mental illness. Moreover, young people struggle to access traditional mental health services where these therapies are delivered. No short interventions specifically tailored for young people have been developed so far. The Imaginator project aims to address the urgent need for an effective and innovative short-term therapy for self-harm in young people. The investigators will pilot a new imagery-based psychological intervention for young people aged 16-25 who experience repetitive self-harm. Mental imagery (the experience of seeing through the mind's eye) can carry intense emotions (positive and negative), and imagining something can facilitate behaviour. Imagery-based therapies have proven useful (i) for problems that feature intense, hard to manage emotions such as those associated with self-harm, and (ii) for promoting healthy behaviour. Our new intervention called Functional Imagery Training will support young people to imagine more adaptive behaviours to cope with the emotional distress that triggers self-harm, and motivate them to reduce self-harm. Imaginator will comprise of just two sessions followed by phone support over three months. Moreover, the investigators will address the challenge of young people accessing and staying in therapy by using a smartphone app to support the therapy, as apps are widely used and favoured by this age group. The app will enable participants to continue with the strategies they have learnt in therapy by themselves, thus ensuring a potential longer-term benefit and self-empowerment.

Detailed Description
-----------------
The problem of self-harm and the need short interventions for young people. Self-harm, an act of self-poisoning or self-injury, irrespective of the apparent purpose of the act is a behaviour used to cope with intense emotions and psychological distress. It can occur in a variety of mental health diagnoses as well as individuals with no diagnosis. Of concern is that almost one in five young adults report self-harm behaviour. A United Kingdom (UK) survey in schools described 13% 15-16 years old had self-harmed during their life and 8% in the last year. Factors associated with self-harm include a disadvantaged socio-economic background, social isolation and lack of support, negative life events including childhood emotional, physical or sexual abuse. Although self-harm is different from suicidality, people who self-harm carry a fourfold risk of suicidal thoughts and behaviours within one year, a risk over and above risk conferred by mental health problems and psychosocial risk factors. Self-harm has substantial personal impacts and costs on the National Health Service (NHS). In Cambridgeshire, the number of hospital admissions for self-harm has been higher than the UK average, making addressing self-harm a significant issue for local primary and secondary health care National Institute for Clinical Excellence (NICE) guidelines recommend offering a psychological intervention that is specifically structured for people who self-harm, with the aim of reducing self-harm. In addition: (i) the intervention should be tailored to individual need, and could include cognitive-behavioural, psychodynamic or problem-solving elements; (ii) therapists should be trained and supervised in the therapy they are offering to people who self-harm; (iii) therapists should also be able to work collaboratively with the person to identify the problems causing distress or leading to self-harm. A number of interventions have been developed and have shown some efficacy at reducing self-harm in adolescents and adults. However these therapies vary between 4 sessions and much longer duration, and currently are mostly available only to individuals under mental health care after variable periods of waiting time. Moreover, almost half of young people referred recommended treatment will not attend any follow-up sessions. There is a lack of short interventions for self-harm specifically targeted at young people. Short interventions that engage young people are urgently needed to allow young people to better manage and reduce self-harm also outside secondary mental health care, and alongside / while waiting for more longterm problems to be addressed (psychiatric disorders, housing and employment difficulties etc.). Developing new treatments for self-harm using imagery-based interventions. Mental imagery is the process of 'seeing through the mind's eye'. Intrusive mental images carrying intense negative emotions are central to several mental disorders. For example, individuals with social anxiety will experience intrusive images of them sweating and blushing intensely while they try to speak to someone, these images will fuel their anxiety about being judged by others and possibly stop them from attending further social situations. Mental imagery associated with self-harm also appears to be a common phenomenon and individuals describe that images associated with self-harm can carry many different emotional meanings (e.g. evoking a sense of relief, or increasing the urge to self-harm), in line with what drives self-harm in every individual. The characteristics of mental images are related to the intensity of emotions and this applies to positive emotions too. For example, more vivid positive imagery has been related to greater excitement during positive mood. Overall, this suggests that mental imagery is a common phenomenon, which many individuals are likely to experience in the context of high emotions, and that mental images could be used to generate helpful emotions. In fact, addressing distressing mental images and promoting positive imagery has been used for trauma, depression and self-harm in personality disorders. The investigators have successfully treated cases with self-harm behaviour using a short course of imagery-focused therapy for Bipolar Disorder. Moreover, mental images can promote behaviour. Imagining something makes it more likely to act, because it simulating the actual event in the mind and it allows individuals to ''pre-experience'' all aspects the event. Hence, via imagining future scenarios individuals may feel more ready to engage in the action successfully. For example, in sports adding mental imagery training (visualising an exercise) to physical practice of an exercise improves performance. Moreover, imagining an action also involves anticipating how emotionally rewarding it is likely to be. This may enhance motivation to act. The more vivid and real-like the mental image of completing a desired action is, the stronger the positive emotion and motivation to actually do it. This type of imagery of healthy behaviour and desired actions has been developed into a therapy called Functional Imagery Training (FIT). FIT encourages individuals to imagine the benefits of working towards their goals, especially the benefits that are expected to happen right away (e.g. feeling good about oneself). So far, FIT has been shown to be a successful approach for interventions to reduce snacking and in addictive behaviours. Based on this, the investigators propose that FIT can train individuals to imagine more helpful behaviours rather than self-harm when distressed. FIT will train vivid and real-like imagery of alternative goals to self-harm, which is likely to produce rewarding and positive emotions. Our FIT protocol will aim to support individuals who self-harm at: (i) identifying helpful behaviours as an alternative goal when they feel like self-harming (e.g. going for a run, listening to music); (ii) by practising mental imagery of the alternative behaviour, boosting the desire to achieve this goal; (iii) succeeding in engaging in alternative behaviours to self-harm. Importantly, FIT will consist of two face-to-face sessions plus five brief telephone support sessions. Therefore it has the potential of offering immediate support for all those young people who are either excluded from or waiting for more complex interventions. The challenge of engaging young people. Imagery-based interventions focus on visual techniques and are easily amenable to be supported by a smartphone app. Smartphone usage by young people is high. Therefore, enhancing a psychological intervention via a smartphone app could be a successful strategy to ensure that young people keep practising the therapy techniques and engaging with what was learned in therapy once the sessions are over and without the need of face to face follow-up. The support of a smartphone app following the FIT sessions can aid overcome barriers to engagement reported in young people. Therefore, the Imaginator study will tailor FIT to young people by adding a smartphone app support, which can make the intervention more interesting and approachable to this age group. The investigators have developed a bespoke app called Imaginator. This app was created collectively via six meetings of a Young People Advisory Group (YPAG: 4 members, 1 male, aged 19 to 22 years old, with a lived experience of self-harm), together with the research team and John Harper, from App Shine Development company. In summary, self-harm behaviour is a highly prevalent problem among young people in the UK (and worldwide), and of particular urgency in Cambridgeshire. It represents a major social and healthcare problem for the community. Currently, there is a lack of short and easily accessible interventions to specifically help young people reduce self-harming behaviour. As mental imagery-based techniques have been used to reduce unwanted emotions and support motivation and helpful behaviour, The investigators propose that Functional Imagery Training (FIT) could represent a successful strategy to reduce self-harm behaviour. FIT is intended as a brief and focused intervention for young people aged 16-25 (regardless of any diagnosis) that can be added to any other pharmacological or psychological therapy. To improve access to and engagement with the intervention by young people, the investigators will deliver FIT supported by a smartphone app developed together with a Young People Advisory Group.
