Short Description of Instrument
The DSM-III-R and DSM-IV criteria describe the K-SADS-PL is a semi-structured diagnostic interview designed to assess current and past episodes of psychopathology in children and adolescents. Probes and objective criteria are provided to rate individual symptoms.
The primary diagnoses assessed with the K-SADS-PL include: Adjustment Disorders, Agoraphobia, Alcohol Abuse, Anorexia Nervosa, Attention Deficit Hyperactivity Disorder, Avoidant Disorder of Childhood and Adolescence, Bipolar Disorders, Brief Reactive Psychosis, Bulimia, Chronic Motor or Vocal Tic Disorder, Conduct Disorder, Cyclothymia, Dysthymia, Encopresis, Enuresis, Generalized Anxiety, Hypomania, Major Depression, Mania, Obsessive Compulsive Disorder, Oppositional Defiant Disorder, Overanxious Disorder, Panic Disorder, Post-Traumatic Stress Disorder, Schizoaffective Disorders, Schizophrenia, Schizophreniform Disorder, Separation Anxiety Disorder, Simple Phobia, Social Phobia, Substance Abuse, Tourette's Disorder, and Transient Tic Disorder.
The probes that are included in the instrument do not have to be recited verbatim, and they are provided to illustrate ways to elicit the information necessary to score each item. The interviewer should feel free to adjust the probes to the developmental level of the child, and use language supplied by the parent and child when querying about specific symptoms.
The K-SADS-PL is administered by interviewing the parent(s), the child, and then achieving summary ratings which include all sources of information (parent, child, school, chart, and other).
ME/CFS-Specific: This instrument is recommended if a research protocol needs to rule out psychiatric comorbidity in children and adolescents.
It takes approximately 45-75 minutes to complete.
