Outcome Measure
Spence Children’s Anxiety Scale – Parent
What it measures?
- The SCAS-P measures anxiety symptoms in children in the general population through parent report. The measure spans six subscales: panic attack and agoraphobia, separation anxiety, physical injury fears, social phobia, obsessive compulsive, and generalized anxiety (Nauta et al., 2004).
- The SCAS-P assists with the identification of elevated anxiety symptoms requiring further assessment in conjunction with clinical interviews. Additionally, it can be used to measure efficacy of treatment (Nauta et al., 2004).
Who is it for?
The SCAS-P is intended to be completed by the parent of a child aged 7-13 years old.
Instrument Quality
- The SCAS-P is widely used globally to assess anxiety symptoms in children with both clinical and research applications. It has been translated and validated for use across several countries with strong psychometric properties (Arendt et al., 2014; Li et al., 2016; Orgilés et al., 2016; Orgilés et al., 2019; Ramme, 2008)
Structure
- 38 items
- 1 additional open-ended question asking “Is there anything else that your child is really afraid of?”
- 4-point Likert scale
- Respondents indicate how frequently (0 = "Never"; 3 = "Always") their child has experienced anxiety symptoms across different situations
Scoring instructions
- Sum all item responses to derive a full-scale score
- Sum the relevant subscale-specific items to derive subscale scores

Score Interpretation
What higher scores mean?
- Higher scores on the SCAS-P indicate increased number and severity of anxiety symptoms.

Severity ranges
* The developers recommend the use of T-Scores and conversion to percentile ranks based on the age and gender of the child (Nauta et al., 2004). A percentile of 50 represents typical anxiety symptoms in an individual, with scores more than 1 SD (or >94th percentile) indicated clinically significant anxiety symptoms. * Normative scores were derived from a sample of 261 (125 males, 136 females; mean age 11.5 (2.0) years) healthy children recruited from Australian (55%) and Dutch (45%) universities (Nauta et al., 2004). * Normative scores by gender and age are also available from a sample of 1857 healthy children recruited from community samples in Australia and the Netherlands (n = 221), United States (n = 477), and the United Kingdom (n = 1069; Brow-Jacobsen et al, 2011; Cresswell et al., n.d.; Nauta et al., 2004; Whiteside et al, 2012).

Reliable change and clinically significant improvement
* The developers recommend the use of T-Scores and conversion to percentile ranks based on the age and gender of the child (Nauta et al., 2004). A percentile of 50 represents typical anxiety symptoms in an individual, with scores more than 1 SD (or >94th percentile) indicated clinically significant anxiety symptoms. * Wampold et al (2001) conducted a meta analysis of psychotherapy outcome studies and noted that the average improvement was reflected in an effect size (ES) of .80. Because a change of 1 SD corresponds to an ES of 1.0, and .80 is considered to be a large ES, Wise (2004) concludes that a change of 1 SD is a defensible indicator of clinically significant change.

Severity ranges
* The developers recommend the use of T-Scores and conversion to percentile ranks based on the age and gender of the child (Nauta et al., 2004). A percentile of 50 represents typical anxiety symptoms in an individual, with scores more than 1 SD (or >94th percentile) indicated clinically significant anxiety symptoms. * Normative scores were derived from a sample of 261 (125 males, 136 females; mean age 11.5 (2.0) years) healthy children recruited from Australian (55%) and Dutch (45%) universities (Nauta et al., 2004). * Normative scores by gender and age are also available from a sample of 1857 healthy children recruited from community samples in Australia and the Netherlands (n = 221), United States (n = 477), and the United Kingdom (n = 1069; Brow-Jacobsen et al, 2011; Cresswell et al., n.d.; Nauta et al., 2004; Whiteside et al, 2012).

Reliable change and clinically significant improvement
* The developers recommend the use of T-Scores and conversion to percentile ranks based on the age and gender of the child (Nauta et al., 2004). A percentile of 50 represents typical anxiety symptoms in an individual, with scores more than 1 SD (or >94th percentile) indicated clinically significant anxiety symptoms. * Wampold et al (2001) conducted a meta analysis of psychotherapy outcome studies and noted that the average improvement was reflected in an effect size (ES) of .80. Because a change of 1 SD corresponds to an ES of 1.0, and .80 is considered to be a large ES, Wise (2004) concludes that a change of 1 SD is a defensible indicator of clinically significant change.
