Psychopathology Study Guide

📖 Core Concepts Psychopathology – scientific study of mental illness; looks at abnormal thoughts, behaviors, and experiences that deviate from social norms. Four‑Ds Model – assesses abnormality on Deviance, Distress, Dysfunction, Duration. General Psychopathology (“p”) Factor – a single dimension that captures shared variance across all psychiatric symptoms, analogous to the “g” factor for intelligence. Classification Systems – DSM‑5 (categorical, clinical) vs. RDoC (dimensional, research‑focused). Descriptive vs. Explanatory Approaches – description lists symptoms; explanation tries to explain why they occur (psychodynamic, CBT, etc.). Common Mental Disorders – depression, generalized anxiety, panic, phobias, social anxiety, OCD, PTSD. Gender Prevalence Patterns – women → internalizing (depression, anxiety); men → externalizing & higher suicide rates. 📌 Must Remember Four‑Ds: abnormality = Deviance + Distress + Dysfunction + Duration (all must be considered). DSM‑5 (2013) = primary clinical diagnostic manual; RDoC = research matrix of six neurobehavioral domains. p factor predicts: greater functional impairment, poorer academic outcomes, higher impulsivity, criminality, suicidality, and more psychiatric diagnoses. Historical shift: from supernatural explanations → Hippocratic brain‑based view → modern biological/psychological models. Gender trend: internalizing disorders ↑ in women; externalizing disorders & suicide ↑ in men. 🔄 Key Processes Diagnosing a Mental Disorder (DSM‑5) Collect symptom report & behavioral observation. Match pattern against DSM‑5 criteria (symptom clusters, duration, severity). Ensure symptoms exceed normal stress responses. Rule out medical/substance causes. Applying the Four‑Ds Check Deviance – does behavior/thought differ from cultural norms? Assess Distress – does the person feel upset or uncomfortable? Evaluate Dysfunction – is daily functioning impaired? Verify Duration – have symptoms persisted long enough per disorder‑specific thresholds? 🔍 Key Comparisons DSM‑5 vs. RDoC DSM‑5: categorical diagnoses, symptom‑based, clinical use. RDoC: dimensional constructs, neurobiological focus, research use. Descriptive vs. Explanatory Psychopathology Descriptive: lists “what” (symptoms, signs). Explanatory: asks “why” (theoretical models). Internalizing vs. Externalizing Disorders Internalizing: mood/anxiety (more common in women). Externalizing: aggression, substance use, impulsivity (more common in men). ⚠️ Common Misunderstandings Deviance = pathology – cultural minority practices can be deviant without being disordered. Distress always present – severe dysfunction can occur with minimal reported distress. p factor = a single disorder – it reflects a shared liability, not a specific disease entity. RDoC replaces DSM‑5 – they serve different purposes; RDoC is not a clinical manual. 🧠 Mental Models / Intuition “Four‑Ds as a checklist” – imagine a traffic light: all four lights must be red (present) before you stop and call it a disorder. p factor as “general psychopathology temperature” – higher “temperature” means more overall symptom load, regardless of specific diagnosis. DSM‑5 vs. RDoC as “map vs. satellite” – DSM‑5 gives you road names (diagnoses); RDoC shows the terrain (underlying processes). 🚩 Exceptions & Edge Cases Duration criteria can miss acute but severe presentations (e.g., brief psychotic episodes). Hallucinations may appear as isolated signs without meeting full disorder criteria. Trait‑disorder overlap – high neuroticism may look like an anxiety disorder but isn’t automatically a diagnosis. 📍 When to Use Which Clinical setting (patient care) → use DSM‑5 for diagnosis, treatment planning, insurance. Research study exploring neural mechanisms → adopt RDoC constructs to align with biomarkers. Screening for overall risk → consider p factor scores (e.g., broadband questionnaires). Cultural assessment → prioritize Deviance check against the client’s cultural norms before labeling pathology. 👀 Patterns to Recognize Co‑occurrence – high p factor scores often accompany multiple DSM‑5 diagnoses. Gender‑linked symptom clusters – look for internalizing symptoms in women, externalizing in men. Historical language – terms like “possession” or “fluid imbalance” signal outdated explanatory models. Four‑Ds alignment – exam questions that list three of the Ds usually expect you to identify the missing fourth. 🗂️ Exam Traps Choosing “distress” as the sole marker – many items will tempt you to pick distress alone; remember all four Ds matter. Assuming RDoC replaces DSM‑5 – a distractor may state RDoC is used for clinical diagnosis; it is not. Equating “p factor” with a single disorder – watch for options that describe it as a specific diagnosis; it’s a dimensional liability. Cultural deviance misinterpretation – an answer that labels a cultural practice as pathological without context is wrong. Duration shortcuts – some items may give a symptom count but omit required time span; remember the duration criterion.
