|---|---|
| Biopsychosocial approach | a holistic, interdisciplinary framework for understanding the human experience in terms of the influence of biological, psychological, and social factors |
| Biological factors | internal, genetic, and/or physiologically based factors, can be innate, such as genetic predispositions passed down from one’s parents, or can come about later in life, such as through taking certain medications |
| Psychological factors | internal factors relating to an individual’s mental processes, including their cognition, affect, thoughts, beliefs, and attitudes |
| Social factors | external factors relating to an individual’s interactions with others and their external environment, including their relationships and community involvement |
| There are two biological factors that contribute to SP | gaba dysfunction , long term potentiation |
| GABA (Gamma-amino butyric acid) | the main inhibitory neurotransmitter in the nervous system, regulates postsynaptic activation in neural pathways, preventing overexcitation and uncontrolled firing. important in flight fight freeze response as it slows the excitatory nueral impulse |
| GABA dysfunction | insufficient neural transmission or reception of GABA in the body |
| what is GABA dysfunction due to | low level or production of GABA, or an insufficient reception or transmission of GABA across the synapse |
| GABA dysfunction can contribute to the development of phobia because: | may cause someone’s flightfightfreeze or anxiety response to be activated more easily than someone with adequate GABA levels. • recurrent stress responses to specific stimuli can lead to the development of a phobia. |
| Long-term potentiation | the long-lasting and experience-dependent strengthening of synaptic connections that are regularly coactivated |
| how does This contributes to the development of phobias pt 1 | strengthen the association between neural signals involved in perceiving a stimulus and neural signals involved in activating the FR. |
| how does This contributes to the development of phobias pt 2 | Through their repeated coactivation, the signals involved in perceiving a phobic stimulus more readily trigger the activation of the neural signals of FR |
| what is the result | The more this occurs, the stronger the association becomes, and the stronger the phobia becomes. |
| psychological factors | precipitation by classical conditioning, perputaation by operat conditioing, role of cognitve biases |
| Classical conditioning | contribute to the development of phobias by increasing susceptibility to and contributing to their occurrence. This can be described as precipitation by classical conditioning. |
| Precipitating factors | factors that increase the susceptibility to and contribute to the occurrence of developing a specific phobia |
| classical condition in terms of contrubting to phobia | classical conditioning can precipitate specific phobia as phobias can be learned, and therefore developed, through classical conditioning. |
| simuli | phobis stimulus=netral stimulus repeated association with unconditioned stimuls nautually induced fear, NS becomes the CS or phobic stimulus producing the conditioned response or phobic response |
| Operant conditioning | operant conditioning perpetuates phobias by preventing an individual from overcoming them, The role of operant conditioning in phobias can be thought about largely in terms of the consequence stage |
| Perpetuating factors | factors that inhibit a person’s ability to recover from a specific phobia |
| consequence stage pt 1 | an individual with a phobia will generally avoid contact with their phobic stimulus at all costs. • by avoiding confrontation with the phobic stimulus, a person is negatively reinforced through this avoidance |
| onsequence stage pt 2 | over time, this reinforcement strengthens or maintains the phobic response, making avoidance behaviours more likely to be repeated and preventing recovery through this cycle.` |
| Cognitive bias | a predisposition to think about and process information in a certain way |
| what does it do | may cause errors in people’s judgements and thoughts. Cognitive biases contribute to phobias because some people consider certain stimuli as particularly harmful, dangerous or scary |
| Memory bias | a type of cognitive bias caused by inaccurate or exaggerated memory |
| Memory bias contribute | people may remember the trauma as extremely significant or harmful, and this impacts their present cognitions about related stimuli, this innacurate memeory serves to jutofy the extreme fear allowing it to persust over time in their mind |
| Catastrophic thinking | a type of cognitive bias in which a stimulus or event is predicted to be far worse than it actually is |
| Catastrophic thinking contribute | often imagine the worst-case scenario possible when imagining an interaction with their phobic stimulus. This contributes to phobia, making stimuli seem worthy of extreme fear and anxiety |
| social factors | • specific environmental triggers • stigma around seeking treatment. |
| Specific environmental triggers | stimuli or experiences in a person’s environment that evoke an extreme stress response, leading to the development of a phobia |
| There are a few different types of environmental triggers, including: | • direct confrontation with a traumatic stimulus or event • observing another person having a direct confrontation with a traumatic stimu.lus or event, • learning about a potentially dangerous or traumatic stimulus or event indirectly |
| Stigma | the feeling of shame or disgrace experienced by an individual for a characteristic that differentiates them from others |
| how | As phobias tend to involve some degree of irrational fear, seeking help can be very difficult,might feel as though their phobia is too embarrassing or insignificant to seek professional help, or unusual and isolated from society in some way for doing so. |
| stigma contributes | Leaving one’s phobia untreated also contributes to the development and maintenance of specific phobia. Often, people will not seek help due to embarrassment, worry, or fear. |
| Biological interventions | gaba agonists, breathing retraining |
| GABA agonists | lack of inhibitory neural transmission in the body leads to over-excitation at the synapses, inability to regulate neural firing can lead to feelings of anxiety. Therefore, combatting GABA dysfunction can reduce the development of specific phobi |
| Benzodiazepines | a type of medication that depresses central nervous system activity and is often used as a short-acting antianxiety medication , are agonists |
| agonists | a type of drug that imitates neurotransmitters and works to initiate a neural response (excitatory or inhibitory) when it binds to the receptor sites of a neuron |
| how does bezodiazepines treat gaba dysfunction | benzodiazepines bind to GABA receptor sites and mimic the effects of GABA to increase its inhibitory response. |
| what does this do | By inducing inhibitory responses, the rapid excitatory communication between neurons in the fear response is reduced, relieving the anxiety it causes and leading to the relaxation of muscles. |
| Breathing retraining | a method used to teach breathing control techniques that may reduce physiological arousal, can be used by an individual when they are experiencing anxiety in the presence of their phobic stimulus |
| what happens to breathing during SP | when facing their phobic stimulus, they often experience fast, shallow breathing as their sympathetic nervous system becomes dominant. This can lead to hyperventilation and the engagement of other sympathetic nervous system responses-increased anxiety |
| step 1 of breathing retraining | psychologist/doctor will teach how to consciously control their breathing. • slow deep inhalations thenslow controlled exhalations • counting slowly when breathing in/out • breathing slowly in through the nose breathing out slowly from the diaphragm |
| step 2 | The learner applies the breathing techniques learnt in step 1 when in the presence of a phobic stimulus. eg by counting aloud or in their head, or imagining the therapist saying the instructions to them when in the presence of the phobic stimulus. |
| what does this do | restores the amount of oxygen in the body to an optimal level to help the parasympathetic nervous system become dominant, in turn decreasing the dominance of the sympathetic nervous system and reducing anxiety. |
| Psychological interventions | Cognitive behavioural therapy (CBT) Systematic desensitisation |
| Psychotherapeutic treatments | treatments that address dysfunctional emotions, thoughts, and behaviours through therapeutic communication |
| Cognitive behavioural therapy (CBT) | a form of psychotherapy that encourages individuals to substitute dysfunctional cognitions and behaviours with more adaptive ones |
| The cognitive component involves: | – identifying negative thoughts and feelings (cognitions) about the issue. – replacing these negative thoughts and feelings with more positive ones. |
| • The behavioural component involves: | – identifying negative behaviours relating to the issue. – developing and maintaining more positive behaviours relating to the issue. |
| what do when treating an indivdual | a therapist first has to work with the patient to identify their cognitions and behaviours that may perpetuate and contribute . Once identified, the therapist and counsellor can then work to modify these unhealthy cognitions and behaviours |
| Cognitions eg | Memory bias • Catastrophic thinking • A belief that the phobia can never be overcome • A belief that the phobia can only get worse • Embarrassment • Extreme fear |
| behaviours eg | Avoidance behaviours in which a person avoids their phobic stimulus and anything related to it at all costs • Not seeking help • Avoiding social activities that may expose a person to their phobia |
| how do these behaviours and cognitions work | The presence of these cognitions and behaviours can mutually reinforce each other and perpetuate a phobia and a stress response |
| what happens Once the individual understands the interrelationship between dysfunctional behaviours and cognition | a therapist will work with them to develop strategies to overcome them, involves identifying both cognitions and behaviours that are healthier, which could potentially replace the dysfunctional ones. C: challenging them as hypotheses, B: healthier ones |
| Systematic desensitisation | a therapeutic technique used to overcome phobias that involves a patient being exposed incrementally to increasingly anxietyinducing stimuli, combined with the use of relaxation techniques |
| how does it work | . Systematic desensitisation operates on the principles of classical conditioning, aiming to de-condition the association between the phobic stimulus and fear, by associating the phobic stimulus instead with relaxation. |
| step 1 | The learning of relaxation techniques, A therapist might teach a patient a technique they can apply to reduce the physiological arousal and anxiety involved in the fear response. |
| includes | One technique commonly used is breathing control, such as that outlined in breathing retraining. |
| step 2 | The development of a fear hierarchy. This involves creating a list of anxietyinducing experiences relating to the patient’s phobia, listed in order of easiest to confront, to the most difficult to confront. |
| step 3 | The gradual step-by-step exposure. The gradual step-by-step exposure to each item of the fear hierarchy, beginning with the least anxietyinducing stimulus, paired with practice of the learnt relaxation techniques with each new exposure. |
| includes | Each exposure to a step in the fear hierarchy is done in a controlled manner, with the use of relaxation techniques at each step. The patient does not move on to the next item in their fear hierarchy until the fear response is eliminated |
| step 4 | The continuation of this systematic exposure. The continuation of this exposure to items on the fear hierarchy until the most fear-inducing stimulus can be faced without producing the phobic response. |
| includes | This process is often done with a therapist. At the end of this stage, a patient can confront their most fear-inducing stimulus without a fear response. |
| Social interventions | Psychoeducation |
| Psychoeducation | teaching families and supporters of individuals with mental health disorders how to better understand, deal with, and treat their disorder |
| includes | providing more general education about the nature of phobia to increase families’ and supporters’ understanding of the mental health disorder. This can be beneficial to both the person with the phobia and their family and supporters. |
| There are two important components of psychoeducation that are taught to families and supporters: | challenging unrealistic or anxious thoughts of the individual, and • not encouraging avoidance behaviours. |
| Challenging unrealistic or anxious thoughts eg form of extreme anxiety, catastrophic thinking, and memory biases. | Family and supporters are encouraged to actively challenge these thoughts to help to understand that some cognitive components of their fears are potentially unfounded and irrational. should be done in a supportive, non-judgemental fashion |
| Not encouraging avoidance behaviours | families and supporters are taught that they should not encourage avoidance behaviours, as they do not solve and only perpetuate the phobic anxiety. |
| why are avoidance techniques bad | might be useful for relieving less severe forms of stress, they do not provide long-term solutions for phobias. This is because phobias involve a deeply ingrained fear response that cannot be eliminated entirely with temporary fixes. |
