Spence Children’s Anxiety Scale – Child (SCAS-Child)

The Spence Children’s Anxiety Scale – Child is a 45-item self-report scale used to assess severity of anxiety symptoms in children aged 8-15 years. The SCAS-Child assesses six domains of anxiety which constitute six subscales:

  • Separation Anxiety
  • Social Phobia
  • Obsessive Compulsive Problems
  • Panic/Agoraphobia
  • Generalised Anxiety/Overanxious Symptoms
  • Fears of Physical Injury

The SCAS-Child can be used as part of a broader diagnostic assessment, but should not be used as the sole means for diagnosis. The scale can be used in clinical and non-clinical settings to evaluate the impact of anxiety interventions over time.

There is also a parent reported version (SCAS-Parent) of the same assessment. Administering the child and parent reported version and comparing results can be helpful to inform a formulation.

Validity and Reliability

The SCAS Child Version has been validated in a sample of Australian children (N = 218) by Spence (1998). The SCAS demonstrated convergent validity with other measures of child anxiety, and discriminant validity with a measure of child depressive symptoms. The same study also showed significantly higher SCAS scores on all six subscales among clinically anxious children than those in a non-clinical control group.

Scoring and Interpretation

Scores consist of a total raw score (range from 0 to 114) and six sub-scale scores, with higher scores indicating greater severity of anxiety symptoms. These scores are also converted into percentiles based on age and gender from normative samples reported on www.scaswebsite.com. A percentile score more than 84 for any subscale score or the total SCAS score indicates clinically significant anxiety symptoms.

Sub-scales are computed by summing the following items:

  • Separation anxiety (items 5, 8, 12, 15, 16, 44)
  • Social phobia (items 6, 7, 9, 10, 29, 35)
  • Obsessive compulsive (items 14, 19, 27, 40, 41, 42)
  • Panic/agoraphobia (items 13, 21, 28, 30, 32, 34, 36, 37, 39)
  • Physical Injury (items 2, 18, 23, 25, 33)
  • Generalised anxiety (items 1, 3, 4, 20, 22, 24)

Items that are not scored in either the total score or the sub-scale scores are:
11, 17, 26, 31, 38, 43, 45 and 46. They are not scored because they did not meet sufficient psychometric requirements.

If the scale is administered on multiple occasions a graph is produced to track symptoms over time, representing  the respondents scores as a normative percentile.
