Behavioral Dynamics Exam 3 Cards Flashcards
Somatization
Physical symptoms that may not be fully explained by a known medical dx after appropriate workup and cause significant distress and functional impairment
Somatization in actual medical conditions
Often severity of pain/symptoms is out of proportion to the disease
3 factors that can influence somatoform disorder development
Family member with chronic illness
History of abuse or sexual trauma
Comorbid psych disorder
Somatic symptom disorder (Somatization)
Multiple unexplained physical symptoms - often in patients accompanied by a sense of urgency with unstable or dyfunctional families
Classic patient for somatic symptom disorder
Pt. describes being sickly their whole life and has had multiple invasive studies/diagnostics
Criteria for Somatic symptom disorder
1+ symptom that causes significant distress or disruption
Persistent thoughts, anxiety, or energy focused on concerns
Symptoms present for over 6 months

1 of the three criteria (thoughts, anxiety, energy)
Moderate somatic symptom disorder
2+ of the three criteria (thoughts, anxiety, energy)
Severe somatic symptom disorder
2+ of the three criteria (thoughts, anxiety, energy) and multiple complaints or one SEVERE complaint

2 things to rule out when considering a diagnosis of a somatic symptom or related disorder
Actual medical problem
Substance use

Factious disorder by proxy
Form of ABUSE
Inducing symptoms on others to make them appear sick
Clinical presentation of factitious disorder

Severe factitious disorder
Wandering with aliases from hospital to hospital - can become aggressive, get admitted and then leave AMA
Signs of factitious disorder imposed on another
S/S worsen when perpetrator is around or when patient has testing or is scheduled for discharge
S/S improve when perpatrator is not around - they show disregard for the patients actual health and are surprisingly agreeable to invasive procedures
Malingering
Faking an illness or symptoms for personal gain - avoids excessive diagnostic tests. S/S improve once goal is acheived
Treatment for malingering
Treat underlying conditions, and avoid manipulation
Treatment for factitious disorders
REPORT by proxy
Be compassionate in discussing diagnosis and try to keep them with one provider2
