PSYCHOTHERAPY:

PSYCHOTHERAPY Psychotherapy is the systematic use of a human relationship for therapeutic purposes of alleviating emotional distress by effecting enduring changes in a patients Thinking , Feelings and Behaviour . ( Strupp , 1986 ) The mutual engagement of the patient and psychotherapist both cognitively & Emotionally , is the foundation for effective psychotherapeutic work. 3/23/2011 3

COGNITIVE BEHAVIOUR THERAPY:

COGNITIVE BEHAVIOUR THERAPY CBT-type of re educative therapy. CT- a system of psychotherapy based on theories of pathological information processing in mental disorders. Mainly directed at modifying distorted or maladaptive cognitions & related behavioral dysfunction . Focused and problem oriented . Emphasizes psycho education Deliberate efforts at readjustment & goal modification-with or with out insight in to cons. conflicts. 3/23/2011 4

History ::

History : Concepts of Greek Stoic philosophers ,Taoism and Buddism . Epictetus, Greek philosopher. Observed that people are not disturbed by things that happen but by the view they take of things that happen. Proposed by Aaron T.Beck -early 1960s. Struck by retroflexed hostility of psychoanalytical theory & observations-negatively biased constructions of self and environment . COGNITIVE THERAPY FOR DEPRESSION -1979 later to others. 3/23/2011 5

PowerPoint Presentation:

ENCHRIDION-ideas or thoughts are controlling factor for emotional lives. Modern philosophers-conscious ideas & meanings attached to events-source of actions. Phenomenological approach to philosophy -Kant ,jaspers , Binswanger,& others influenced C.T. Adler ,Honey .Alexander & Sullivan-perceptions of self & conscious experience. 3/23/2011 6

PowerPoint Presentation:

Kell ’ s theory of personal constructs and developmental psychology –schemas . Ellis rational emotive therapy- promulgate CT. Wright & Thase – combining CT & phar. Therapy. Review of Evolution of CT- Beck in 1993- fulfill criteria for a system of psychotherapy. 3/23/2011 7

CRITERIA FOR A SYSTEM OF PSYCHOTHERAPY:

CRITERIA FOR A SYSTEM OF PSYCHOTHERAPY A comprehensive theory. Empirical support for the theory. An operationalized therapy based on theoretical principles. Empirical evidence for effectiveness of the psychotherapy. 3/23/2011 8

the cognitive model :

the cognitive model Characteristic errors in information processing in psychiatric disorders and alterations in thought process are closely link to emotional reactions and dysfunctional behaviour patterns – Beck. E.g.. the negative cognitive triad of self , world ,& future . Over estimation of danger – anxiety . Cog . Model –NOT presume cog. Path.-cause of specific syndromes ; other factors involved in etiology. 3/23/2011 9

WORKING MODEL FOR CT:

WORKING MODEL FOR CT 3/23/2011 14

The Cognitive Model:

The Cognitive Model Core Beliefs Assumptions Compensatory/coping strategies Situation Automatic thoughts/images Reaction (emotional/behavioral physiological)

MODEL FOR INF.PROCESSING:

MODEL FOR INF.PROCESSING 3/23/2011 16 Activation of Relevant schema Perception of event Altered information Processing Automatic thoughts Behavioral symptoms Emotional Symptoms

PowerPoint Presentation:

3/23/2011 17 Situation : A Classmate brushes past me in the library without saying “hello “ . I am unlovable I Need her approval to feel worthwhile She Doesn ’t like me Emotion : Sad , Depressed , Hopeless

Levels of dysfunctional cognition:

Levels of dysfunctional cognition Beck & colleagues – 2 major levels a. automatic thought s . b. schemas . Automatic thoughts – cognitions that occur rapidly in a situation or recalling an event . - not subjected to rational analysis and based on erroneous logic . 3/23/2011 18

PowerPoint Presentation:

3/23/2011 19 Automatic Negative Thoughts Schemas Cognitive errors

PowerPoint Presentation:

Faulty logic – cognitive errors-translate between ANT and SCHEMAS COG. Errors during affective arousal – narrow attention simplify info .processing & intensify beh .responses . 3/23/2011 20

Cognitive errors:

Cognitive errors Selective abstraction (mental filter ) Arbitrary inference Absolute thinking (all or none thinking) Maximizing & minimizing Personalization Over generalization Catastrophic thinking Selective negative focus Jumping to conclusions 3/23/2011 21

Schemas :

Schemas Def : Are deeper cognitive structures that contain the basic rules for screening, filtering & coding inf. from environment. Develop through childhood experiences & formative influences. ( Bowlby 1985 ) Play adaptive role in assimilation of data & decision making. In psy . disorders-clusters of maladaptive schemas-resulting in dysphoric mood & ineffective or self defeating behavior. 3/23/2011 22

SCHEMAS:

SCHEMAS Types : 1.simple 2.intermediary. 3.corebeliefs (D .A . Clark). Maladaptive schemas-lie dormant; triggered by stress. Newly emerged schemas influences-superficial level of cog .functioning.-episodic dis In chronic conditions-consistent schemas – which are resistant to change . 3/23/2011 23

Proposed maladaptive schemas:

Proposed maladaptive schemas Dependence Subjugation- lack of individuation Vulnerability to harm/ illness Fear of losing self -control 3/23/2011 24 Autonomy

PowerPoint Presentation:

3/23/2011 28 Relatively stable structures which guides the ways in which we mold data into cognitions activated by certain situations Key assumptions about ourselves our experiences and our future - Underlying our ATs Rapid , Surface level thoughts that directly influence emotions without necessarily being aware

Behavior model:

Behavior model Based on learning theories. in classical conditioning (Ivan Pavlov) – CS paired with UCS – UCR In operant conditioning ( B. F . Skinner ) –in a stimulus situation a response is followed by favorable or unfavorable consequences. in observational learning (Albert Bandura) – an observer attends to a model’s behavior and its consequences . 3/23/2011 30

Behavior model:

Behavior model Behavior therapies involve the application of learning principles to direct efforts to change mal adaptive behaviors . They are based on certain assumptions – 1. it is assumed that behavior is a product of learning . 2. it is assumed that what has been learned can be unlearned . 3/23/2011 31

Preparation of patient:

Preparation of patient Active participants in tryout new strategies To do home work Out come monitored & may be altered Focused on symptoms & time limited Incorporation of therapy into day today life 3/23/2011 51

Structuring therapy:

Structuring therapy Preparing therapy agenda by therapist & pt. Usually 2-4 items per each session Over whelming problems in to workable segments. Constructive feed back to provide significant opportunities for change. Decision to deviate from agenda-made by both. Assign home work to link sessions together . 3/23/2011 52

3.Final phase:- prep. for termination -frequency – reduced . -transfer from therapist to pt. -focuses on relapse prevention Anticipation of future stressors Identi . Of prodromal symptoms Self help procedures. Est. guidelines for return 3/23/2011 55

Intensity & duration of treatment :

Intensity & duration of treatment OP. CBT- 1 or 2 /wk , for severe cases 3-daily. pharmacotherapy & Computer Assisted Therapy with CBT- can reduce sessions to every other week / 20-25 min sessions reduces . Good therapeutic relationship Frequently held cession. In most cases - 3-6 months Unsuccessful therapy - 12-16wks /OP Not to be terminated – achieve sym .relief At least 2-3 /alt wk before termination 3/23/2011 56

predictors for out come:

predictors for out come Chronicity & severity of symptoms- poorer response. High levels cognitive dysfunction in depression –good response. Good pre morbid history-suitable for CT. Above average intelligence- not a predictor. Simplified procedures for sub normal intelligence. Flexible approach for pts needs. 3/23/2011 57

Out come assessment :

Out come assessment Therapist administered scales – 1.Hamilton Anxiety Rating Scale. 2. Hamilton Depression Rating Scale. 3.Yale Brown Obsessive Compulsive Scale Self report assessment : 1 . Beck Depression Inventory. 2 . Fear Survey Schedule . 3 . Fear Questionnaire . 4 . Hopkins Symptoms Check List . These scales administered Before and during treatment. 3/23/2011 58

PowerPoint Presentation:

The Dysfunctional Attitude Scale. Attributional Style Questionnaire. Automatic Thoughts Questionnaire……to evaluate distorted cognitions. High residual sym.-risk of relapse. High score of Hopelessness scale- risk of suicide. 3/23/2011 59

Augmentation of therapy :

Augmentation of therapy To add drugs Often combines both forms from the beginning. pharmacological stabilisation before CBT-some axis 1. Both used in combination - clear lines Severe refractory cases may benefit from combine therapies Inc. frequency of visit, switching emphasis involving spouse or family members . Computer augmentation 3/23/2011 60

D-cycloserine(DCS) and CBT:

D- cycloserine (DCS) and CBT DCS is effective in augmenting CBTs that incorporate exposure and desensitization tech in several anxiety disorders ( Panic, Social Anxiety and Specific phobia.) Wilhelm and colleagues used DCS to augment CBT in the treatment of OCD. In the study they concluded that DCS group had a sig. improvement compared to placebo group at mid-treatment. DCS had an effect on OCD symptoms after 5 CBT sessions suggests that it may be a useful augmentation strategy for OCD. 3/23/2011 61

PowerPoint Presentation:

In all the OCD studies difference between the DCS and placebo groups were found when DCS administered 1 to 2 hrs before therapy sessions, but not when administered 4 hrs before. Animal studies concluded that DCS more effective when given immediately before or even after extinction exercises. Its one of the solid foundation of fear extinction. DCS seems to be effective at low doses(50 mg) and has no more side effects. 3/23/2011 62

Efficacy in depression:

Efficacy in depression Acute treatment phase studies : Metanalyses of numerous studies – CT equals to or superior over others . Dobson 1989 , Gaffan et al 1995 ,Robinson et al 1990,Elkin et al 1989,95, DeRubeis et al 2005,Miller et al 2005 ,Thase et al 1991- support the above. 3/23/2011 63

Efficacy in depression:

Efficacy in depression Long term studies :over 1-2 yrs of follow up- lower risk of relapse . Kovacs et al 1981 ,Black burn et al 1981,Unive. of Pennsylvania, Holan et al 2005, Fave et al 1996,2004,jarrett et al 2001- reduces relapse from 47% -29%. Jarrett et al 2001 examined C –phase CT & confirmed at risk pts for relapse & demonstrated the efficacy in protection. Fully remitted pts –no benefit . 3/23/2011 64

PowerPoint Presentation:

3/23/2011 65 Evans et . Al. 1992

Efficacy in OCD:

Efficacy in OCD Effective & frequently used for OCD. Response Rates 50-70% ( Emmelkamp & Beans 1991 ) Behavior Strategies take Precedence over cognitive interventions with Exposure & Response prevention ( Emmelkamp & Beans 1991 ) 3/23/2011 66

Efficacy in anxiety disorders:

Efficacy in anxiety disorders Most authours recommended both cog. & beh.measures -Barlow Cerney1988; Beck et al. 1985a. D.M.Clark et al.1985-behavioural measures –useful in panic disorders . and greater reductions in anxiety , catastrophic cognitions &frequency pf panic attacks. Uncontrolled study at university of Pensylvania , j.g beck et al.1994;Craske et al.1995;Heldt et al.2006; have supported the above . 3/23/2011 67

PowerPoint Presentation:

In GAD-studies of Hollon &Beck1994,Power et al.1990,Butler et al.1991,University of Pennsylvania ,Davidson et al.2004,D.M.Clark et al.2003, & Stangier et al.2003 support efficacy. In PTSD –Mc Donagh et al.2005 , Foa et al 2005(n=171), Kubany et al .2004 , Bisson et al 2004 support superiority of CT 3/23/2011 68

In eating disorders:

In eating disorders Agras et al 1992,2000;Bnasiak t al.2005 ; Carter et al.2003;Cooper et al.1996,Fairburn et al.1991,1993,1995;……have supported. Reduces binge behaviors from 73% to93% &complete remission in51%-84% of cases. CT&IPT were superior to beh . therapy; CT most effective in modifying extreme dieting, emesis ,dysfunctional attitudes(Fairburn et al) CT superior over IPT ( Agras )&along with drugs than drugs alone . 3/23/2011 69

In psychosis:

In psychosis Reported to reduce symptoms of sciz .( Garety et al.1994;Tarrier et al.1993) Metaanalysis of 14 invest. Completed between 19940-2004-suggested sign. Adjunctive procedure. Drury et al.1996-improvement of positive sym. &reduced time for recovery 3/23/2011 70

Bipolar disorder:

Bipolar disorder Few randomized controlled studies SCOTT et al 2001 (n=42),Lam et al 2003(n=103),Ball et al 2006-decrease in relapse rate Suggested booster sessions or maintenance therapy. 3/23/2011 71

Others….:

Others…. Personality disorders Substance abuse 3/23/2011 72

Acceptance and Commitment Therapy:

Acceptance and Commitment Therapy ACT is rather an reformulation of Skinnerian radical behaviorism. Mainly hints at the basic premise of the causative interplay between cognitions, behaviors and emotions. Although different from CBT, similar by techniques known as acceptance , cognition delusion , being present , self as context, values and committed actions. 3/23/2011 73

PowerPoint Presentation:

Major aspect is the notion of acceptance. Method: By encouraging patients to embrace negative thoughts and feelings, such as pain and anxiety, pain and guilt rather than attempting to change and eliminate them, patients begin to learn that acceptance can be more important alternative to experience avoidance. By meta analysis ACT for a range of mental disorders and physical problems like anxiety, depression , psychosis and smoking cessation 3/23/2011 74
