title: [Familial aspect and phonological disorder].
abstract: BACKGROUND
  Phonological disorder.
  
  
  OBJECTIVE
  To verify the phonological processes used by phonologically disordered children with and without family history of speech and language disorders; the association between the phonological processes; the difference between the Percentage of Correct Consonants-Revised (PCC-R) severity index regarding family history.
  
  
  METHODS
  Participants were 104 subjects--25 phonologically disordered children--with no history of previous speech-language therapy, living with their biological parents and siblings. The material used was a child development questionnaire and the phonology tests of the Teste de Linguagem Infantil-ABFW.
  
  
  RESULTS
  Liquid simplification was the most observed process independently of family history; the phonological process of devoicing was mostly observed when the family members presented phonological disorders; the phonological process observed in children are, in general, different from those presented by the family nucleus, and those that are similar do not determine characteristics of family history since they are processes frequently observed in subjects with phonological disorders; the PCC-R severity index did not differentiate types of phonological disorders regarding family history.
  
  
  CONCLUSIONS
  This research shows characteristics that indicate that family history of speech and language disorder is associated to phonological disorders. The knowledge about the child's family history facilitates the planning and execution of early intervention actions, preventing the aggravation of phonological disorders. The PCC-R severity index does not differentiate types of phonological disorders regarding family history.
