Things to keep in mind:
         Children express emotion in a more concrete manner (ask “Do you feel like crying” instead of “Are you sad”)
         Kids much more likely than adults to have comorbid mental disorders, making diagnosis more complicated
         Psychological testing instruments
                o    Stanford-Binet Intelligence Scale: IQ test used in young children
                o    Wechsler Intelligence Scale for Children-Revised (WISC-R): most widely used in school-age children, yields a verbal score, performance score, and full-scale IQ score

Choosing a Medication Depends on 1) prior pt or family member response 2) side-effect profile 3) available form
Side Effects
           Anticholinergic: esp. low-potency antipsychotics; sxs include dry mouth, blurry vision, urinary retention, constipation; anticholinergic delirium; anti-ACh properties counter the EPS
           Reduced seizure threshold: low-potency typicals + clozapine; tx seizures resulting from antipsychotic tx by a) changing meds b) lowering dose c) adding antiseizure med
           Hypotension: orthostatic; esp. with low-potency agents and risperidone; d/t alpha-2 blockade
           Agranulocytosis: clozapine
           Cardiac: low-potency antipsychotics and risperidone may cause QT prolongation (and risk of torsades de pointes)
           Movement d/o: dystonia, EPS, akithisia, NMS, tardive dyskinesia
           Other: skin/ocular pigmentation, photosensitivity

PSYCHOANALYTIC/PSYCHODYNAMIC   Unconscious motivations and early developmental influences are essential to understanding behavior. 3 20 th century schools of psychodynamic psychology are:
Drive Psychology               Infants have sexual and other drives, and advance               Developmental Stages:
                               sequentially through psychosexual developmental stages          Oral
Ego Psychology                 Id, ego, superego; major fxn of ego is reduction of anxiety;    Ego Defense Mechanisms:
                               ego defenses are psychic mechanisms that protect ego from       Feelings or ideas that are distressing to the ego are…

                                                                                               Projection: attributed to others
                                                                                               Regression: reduced by behavioral return to an earlier development phase
                                                                                               Repression: relegated to the unconscious
                                                                                               Reaction formation: converted into their opposites
                                                                                               Displacement: redirected to a substitute that evokes a less intense emotional response
                                                                                               Rationalization: dealt with by creating an acceptable alternative explanation
                                                                                               Suppression: not dealt with, but remain components of conscious awareness
                                                                                               Sublimation: converted to those that are more acceptable
Object Relations Theory        Objects refer to important people in one’s life
Erikson’s Life Cycle Theory    Psychosocial events drive change, leading to a                  Life Cycle Stages:
                               developmental crisis                                            Trust v. mistrust (birth to 18 mo)
                               Each stage presents core conflicts produced by the              Autonomy v. shame (18 mo to 3 yrs)
                               interaction of developmental possibility with the external      Initiative v. guilt (3-5 yrs)
                               world                                                           Industry v. inferiority (5-13 yrs)
                               Individual progress and associated ego development occur        Identity v. role confusion (13-21 yrs)
                               with successful resolution of the developmental crisis          Intimacy v. isolation (21-40 yrs)
                               inherent in each stage                                          Generativity v. stagnation (40-60 yrs)
                                                                                               Ego integrity v. despair (60 yrs to death)
Cognitive Theory               Subjective experience of oneself, others, and the world         Cognitive Distortion is a principle type of irrational belief. Types:
                               Irrational beliefs about oneself, the world, and one’s future   Arbitrary Inference: drawing a specific conclusion w/o sufficient evidence
                               can lead to psychopathology                                     Dichotomous thinking: tendency to categorize experience as “all or none”
                                                                                               Overgeneralization: forming and applying a general conclusion based on an isolated event
                                                                                               Magnification/minimization: over- or under-valuing the significance of a particular event
Behavioral Theory              Behaviors are fashioned through various forms of learning,      Modeling: form of learning based on observing others and imitating their actions and responses
                               including modeling, classical conditioning, and operant         Classical Conditioning: form of learning in which a neutral stimulus is repetitively paired with a natural

                                                                                               Operant Conditioning: form of learning in which environmental events (contingencies) influence the
