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:
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.
The SCAS Child Version has been validated in a large sample of Australian children (N = 4,916) by Spence (n.d.). The SCAS demonstrated convergent validity with other measures of child anxiety, and discriminant validity with a measure of child depressive symptoms (Spence et al., 2003). 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.

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 a large normative sample (N = 4,916) reported by Spence (n.d.) and accessible 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:
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.
