PARENT SCAS Norms

The orginal normative data were reported by Nauta, Scholing, Rapee, Abbott, Spence and Waters. (2004). A parent report measure of children's anxiety. Behaviour Research and Therapy. 42 (7), 813-839. This sample included 261 children and teens aged 6-18 years from Australia and the Netherlands. 
This paper is a useful reference if you want norms for older teens. 

More recent normative data is now available (see below) and these are used for determining the T-Scores for children aged 7-9yrs and 10-13 years.  

Means and Standard Deviations of SCAS-P Subscales and Total Score for a Large Community Sample Aged 7-13 years. 

More recent normative data were computed using community samples from Australia, the Netherlands, the USA and the UK, obtained from the following sources:

a) Nauta, Scholing, Rapee, Abbott, Spence and Waters. (2004). A parent report measure of children's anxiety.Behaviour Research and Therapy, 42(7), 813-839. Dutch and Australian Samples: N=221

b) Brown-Jacobsen, A. M., Wallace, D. P., & Whiteside, S. P. H. (2011). Multimethod, Multi-informant Agreement, and Positive Predictive Value in the Identification of Child Anxiety Disorders Using the SCAS and ADIS-C. Assessment, 18(3), 382-392. USA Sample: N= 54

c) Whiteside, S. P. H., Gryczkowski, M. R., Biggs, B. K., Fagen, R., & Owusu, D. (2012). Validation of the Spence Children's Anxiety Scale's obsessive compulsive subscale in a clinical and community sample. Journal of Anxiety Disorders, 26(1), 111. USA Sample: N=423

d) Data from 2 studies conducted by Prof Cathy Creswell and colleagues at the University of Reading in the UK. UK Samples: N=708 and N = 361

I am extremely grateful to these researchers for allowing me to use their data in order to provide a sample size large enough to compute T scores.

The values for means and standard deviations for each gender and age group are shown in the table that you can download from the link below. The results revealed small but significant differences in mean scores across genders and age levels, necessitating separate calculation of T-scores according to age and gender of the child. Please note that the means and SDs shown here differ slightly from those reported in the original paper by Nauta et al as the age groups are different.
