Psychiatric Diagnostic Formulation

Introduction to the 5 P's Framework

The American Academy of Child and Adolescent Psychiatry recommends organizing psychiatric diagnostic formulation around five key factors: Predisposing, Precipitating, Perpetuating, Protective, and Presentation factors, to create a comprehensive biopsychosocial understanding of the patient's illness 1, 2

Biological predisposing factors, such as family history of psychiatric disorders, acquired insult to the developing brain, autonomic hyperreactivity, and chronic medical conditions, increase the risk for developing psychopathology 1, 2
Psychological predisposing factors, including insecure attachment patterns, maladaptive cognitive schemas, and ego deficits, contribute to the development of psychiatric disorders 1, 2
Social predisposing factors, such as history of stressful or traumatic life events, anxiogenic parenting behaviors, and social skills deficits, also play a role in the development of psychopathology 1, 2

Acute life stressors, specific traumatic events, major life transitions or losses, and environmental changes that disrupt functioning can precipitate symptom onset 1, 2, 3

Patient-level perpetuating factors, including ongoing maladaptive coping strategies, avoidance behaviors, and poor treatment adherence, maintain or worsen symptoms over time 1, 2, 3
Family-level perpetuating factors, such as continued anxiogenic parenting behaviors, family accommodation of symptoms, and high expressed emotion, also contribute to the maintenance of symptoms 1, 2, 3
Community/environmental perpetuating factors, including ongoing exposure to stressors, lack of access to appropriate treatment, and peer reinforcement of maladaptive behaviors, can further exacerbate symptoms 1, 2, 3

Individual protective factors, such as cognitive abilities, positive temperament traits, adaptive coping mechanisms, and motivation for treatment, can ameliorate symptoms and improve outcomes 1, 2, 3, 4
Family protective factors, including supportive family relationships, secure attachment patterns, effective parenting skills, and family cohesion, also promote health and optimize disease management 1, 2, 3
Community protective factors, such as strong social support networks, access to quality healthcare, educational and vocational opportunities, and cultural or spiritual resources, can provide additional support and leverage points for intervention 1, 2, 3, 4

The presentation of the illness, including the current symptom profile and functional status, should be considered in conjunction with the 5 P's framework and the biopsychosocial model to optimize treatment planning 1, 2, 4, 5
The American Academy of Child and Adolescent Psychiatry recommends a comprehensive and individualized approach to treatment planning, taking into account the unique constellation of factors for each patient 1, 2, 3
