Developmental psychopathology

Developmental psychopathology is the study of the development of psychological disorders, such as psychopathy, autism, schizophrenia and depression, with a lifecourse perspective.[1] A main idea is that psychopathology can be best understood as normal development gone awry.[2]

Theoretical basis

Developmental psychopathology is a sub-field of developmental psychology and child psychiatry characterized by the following (non-comprehensive) list of assumptions:

  1. Atypical development and typical development are mutually informative. Therefore, developmental psychopathology is not the study of pathological development, but the study of the basic mechanisms that cause developmental pathways to diverge toward pathological or typical outcomes;
  2. Development leads to either adaptive or maladaptive outcomes. However, development that is adaptive in one context may be maladaptive in another context, and vice versa;
  3. Developmental change is influenced by many variables. Research designs in developmental psychopathology should incorporate multivariate designs to examine the mechanisms underlying development;
  4. Development occurs within nested contexts (see Urie Bronfenbrenner);
  5. This field requires that development arises from a dynamic interplay of physiological, genetic, social, cognitive, emotional, and cultural influences across time.

Origins of the academic field

Dante Cicchetti is acknowledged to have played a pivotal role in defining and shaping the field of developmental psychopathology.[3] While at Harvard University, Cicchetti began publishing important papers on the development of conditions such as depression and borderline personality disorder, in addition to his own work on child maltreatment and mental retardation. Then, in 1984, Cicchetti edited both a book and a special issue of Child Development on developmental psychopathology that served to acquaint the developmental community with this emerging discipline. In that special issue he himself wrote a seminal, defining paper titled, "The emergence of developmental psychopathology."[4]

These efforts were critical in launching what was to become one of the most vital fields in all of developmental science. Subsequently, the emergence of the field was crystallized in 1989 with the publication of the first of the 9 distinguished volumes of the Rochester Symposia on Developmental Psychopathology, as well as with the inaugural issue of the journal Development and Psychopathology.

Development of conduct problems

One form of developmental pathology is conduct disorder. Conduct disorder grows progressively worse over time and behavior considered annoying as a child is considered pathological as the child gets older. The Oregon Social Learning Center has done considerable research on the development of conduct disorder.[5]

Gerald R. Patterson and colleagues take a functionalist view of conduct problems in line with a behavior analysis of child development. They have found considerable evidence that the improper use of reinforcment in childhood can lead to this form of pathology.[6]
