SOCIAL REHABILITATION Social Rehabilitation is an assessment of : A clients capacity to function in a number of areas Identification of clients needs Identification of options to meet these needs How functional incapacity may impact on return to work processes

COGNITIVE BEHAVIOUR THERAPY (CBT) Is a type of therapy consisting of both behavioural strategies (e. g. changing unhelpful behaviours, countering avoidance, increasing helpful behaviours etc) and cognitive interventions (e. g. changing unhelpful beliefs and attitudes, modifying the way a situation or individual is appraised, looking for evidence to support beliefs, problem-solving etc) Aims for changes to emotional distress and unhelpful behaviour by directly evaluating and changing thoughts and behaviours Is a theoretical framework that guides formulation and individualised treatment

CBT Is an evidence based therapy Is based on an ever evolving formulation & conceptualisation of the client & his/her problems in CBT terms Requires a sound therapeutic alliance and active participation by clients Is goal oriented and problem focussed, aims to be time limited, to relieve symptoms and return to usual levels of functioning ASAP Teaches people to be their own therapist Relapse prevention is emphasised

CBT Feelings are determined not by events but by thoughts about events Information processing biases lead to, or maintain depressed / anxious affect & behaviour CBT does not contrast with biological approaches Thoughts, moods, behaviours, biology, environmental & developmental factors are all considered CBT does not come from a single unitary psychological theory but draws on many aspects of learning theory and cognitive psychology

CHRISTINE PADESKY’S FIVE PART MODEL

EFFICACY RESEARCH The efficacy of CBT for depression in particular and other disorders is well supported The competence of therapist matters There is over 40 years of efficacy research, difficult to summarise the findings but some general conclusions can be made CBT is about as effective as medications, when each is adequately implemented Patients treated with CBT less likely to relapse CBT has an enduring effect that prevents relapse in much the same way continuing with medications does CBT may cost more initially but is considered to be more cost effective in the long term

DEPRESSION Marked depressed mood Loss of interest and enjoyment in usual activities Reduced self-esteem and confidence Guilt, worthlessness, pessimism about the future Changes to sleep, appetite, libido Lack of energy, fatigue, reduced activity Changes to concentration & attention Difficulty making decisions Suicidal ideation and behaviour Negative view of self, other people, the world in general and the future

TREATING DEPRESSION USING CBT Behavioural interventions such as activity monitoring and activity scheduling, increase ‘achievement’ and ‘pleasurable activities’, problem solving, behavioural experiments, stimulus control strategies for insomnia The goal is to return to usual activities as soon as possible OT’s support this by helping the client structure meaningful and purposeful activities into their day, help prompt and initiate activity, break tasks into smaller components, practical support for behavioural experiments etc

TREATING DEPRESSION USING CBT Cognitive strategies such as learning to control anxiety, identifying and evaluating distressing thoughts and beliefs, learning new skills and strategies, relapse prevention OT’s support this by prompting clients to complete homework assignments, assisting them to engage in activities to put the new skills into practice, reminding them to use new skills and strategies in stressful situations

ANXIETY DISORDERS Many different disorders but common features Specific and recurring fears + physiological symptoms Responses can be broken down into 4 domains: physiological (autonomic nervous system arousal) cognitive (perception of danger, threat, loss, worry) affective (nervousness, fear) behavioural (fight, flight or freeze) Anxiety may become a problem due to intensity, duration, impairment or avoidance Anxiety arises from misperception of situation Anxiety itself interpreted as threat in vicious cycle

ANXIETY DISORDERS Clients with anxiety disorders: Overestimate the probability of a feared event Overestimate the severity of a feared event Underestimate their own coping resources Underestimate likely rescue factors Maintaining factors: Escape and avoidance maintain preoccupation with threat and prevent unambiguous disconfirmation Cognitive biases such as catastrophising; dichotomous thinking; mental filtering and personalisation Safety-seeking behaviours: may exacerbate bodily symptoms; contaminate social situations; prevent disconfirmation of beliefs

TREATING ANXIETY USING CBT Goals are to tolerate and control physical symptoms of anxiety, address and test out worrying thoughts (catastrophic predictions) To return to usual activities as soon as possible (drop avoidance and other safety-seeking behaviours) Uses education, strategies to address physical symptoms, to identify and evaluate anxious thoughts and beliefs, and to identify and modify behavioural responses to anxiety

SAFETY-SEEKING BEHAVIOURS & AVOIDANCE Are strategies that are used minimise anxiety and to cope in specific situations Vary from client to client and disorder to disorder Can be either behaviours or thoughts / beliefs Can be anticipatory and or occur as a ‘post-mortem’ Can be automatic, are viewed as helpful and can be resistant to change BUT. . Maintain anxiety – don’t get to learn that the feared event doesn’t occur or that you can cope Reduce the likelihood of change, unless identified and addressed

BEHAVIOURAL EXPERIMENTS Key component of treating anxiety Examples include dropping safety-seeking behaviours or avoidance Are developed as part of an individual conceptualisation Test out predictions of danger, coping etc Usually involve combination of exposure and ‘disconfirmatory manoeuvres’, aim to reduce belief that the danger will occur to zero

OCCUPATIONAL THERAPISTS ROLE To support the client to initiate and complete behavioural experiments in the ‘real world’ To prompt them to drop safety-seeking behaviours, to use helpful skills and strategies To support the client to stop avoiding feared situations To help with a graduated return to regular activities To go into the workplace & identify possible barriers and problem-solve solutions Facilitate communication between employer and client

CASE MANAGERS CAN ASSIST BY Referring to clinical psychologist early if anxiety and depression are factors affecting a return to work Referring to an OT for a workplace assessment early to cement the expectation clients will return to their usual activities as soon as possible Encouraging clients to attend sessions Considering combining Clinical Psychology referrals with referrals to an Occupational Therapist Facilitating professionals meetings to review progress, coordinate treatment planning etc
