Social-Emotional Developmental Age Level (SEDAL)

The Social-Emotional Developmental Age Level (SEDAL) is a behavioural assessment scale designed to establish social-emotional progress in children and adults with a developmental age between 0 and 14 years.

The social development domain focuses on:

  • initiating contact
  • social independence
  • moral development
  • impulse control
  • self-awareness in social contexts
  • social assessment skills
  • social skills
  • relating to authority
  • social aspects of sexual development.

The emotional development domain focuses on:

  • self-image
  • emotional independence
  • sense of reality
  • moral development
  • fears
  • impulse control
  • regulation of emotions.

By measuring the domains separately, SEDAL is able to calculate a developmental age level for each domain individually, as well as a global score combining the two.

Age range

Birth–14 years, 11 months
