This study tracked children with specific language impairment (SLI) over time. While patterns of difficulty showed stability, 45% of children shifted between identified subgroups by age 8.

Area of Science:

  • Developmental linguistics
  • Child psychology
  • Speech and language therapy

Background:

  • Specific language impairment (SLI) affects a significant number of children.
  • Accurate classification of SLI subgroups is crucial for targeted interventions.
  • Previous research identified 6 distinct subgroups of children with SLI.

Purpose of the Study:

  • To examine the longitudinal stability of 6 previously identified subgroups of children with SLI.
  • To assess the consistency of SLI classifications over a one-year period.
  • To compare the stability of the 6-subgroup system with a 3-subgroup classification.

Main Methods:

  • Longitudinal study design.
  • Involved 242 seven-year-old children attending language units in England.

  • Data collected at age 7 and re-evaluated at age 8.

    • Main Results:

    • Considerable stability was observed in the patterns of difficulties within the 6 subgroups.
    • However, 45% of children changed their subgroup classification between ages 7 and 8.
    • The membership stability was comparable to that of a 3-subgroup classification system.

    Conclusions:

    • The 6-subgroup classification system demonstrates reasonable stability for identifying patterns of SLI.
    • The movement of children between subgroups highlights the dynamic nature of language development in SLI.
    • Further research is needed to refine classification systems for children with SLI.
