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

The scale includes six additional positive filler items (for a total of 44 items), with responses recorded on a 4-point scale ranging from 0 (never) to 3 (always).

The SCAS-Child measures six distinct anxiety dimensions:

1. Separation Anxiety – assessing distress related to separation from caregivers or home
2. Social Phobia – measuring fear and avoidance of social situations
3. Obsessive Compulsive – evaluating repetitive thoughts and behaviours
4. Panic/Agoraphobia – assessing panic symptoms and fear of public places
5. Physical Injury Fears – measuring specific phobias related to physical harm
6. Generalised Anxiety – evaluating excessive worry and physical symptoms

For clinicians, the SCAS-Child offers several distinct advantages, particularly in both educational and clinical settings where understanding the specific nature of a child’s anxiety is crucial for intervention planning. Its comprehensive coverage of anxiety domains makes it particularly valuable for identifying specific areas of concern during initial assessment. Its alignment with diagnostic categories supports clinical decision-making and referral processes, while its ability to differentiate between various types of anxiety types facilitates treatment selection. The measure also enables tracking changes in specific symptom clusters over time, aiding in monitoring treatment effectiveness.

A parallel parent version (SCAS-Parent) is available, excluding the positive filler items but maintaining the same 38 anxiety-focused items. The availability of both child and parent versions enables clinicians to gather multiple perspectives on the child’s anxiety symptoms, enhancing diagnostic accuracy and treatment planning.

SCAS-Child 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 of 85 and above for any subscale score or the total SCAS score indicates elevated and clinically relevant anxiety symptoms.

Sub-scales are presented for the SCAS-Child:

• Separation anxiety (items 5, 8, 12, 15, 16, 44; range 0-18): Assesses a child’s distress when separated from their primary caregivers or home environment. Includes fears about being alone, worry about harm befalling family members, and reluctance to go to school or sleep away from home.
• Social phobia (items 6, 7, 9, 10, 29, 35; range 0-18): Measures fear and avoidance of social situations, including performance anxiety and social evaluation concerns. This includes worries about speaking in class, meeting new people, and fear of embarrassment.
• Obsessive compulsive (items 14, 19, 27, 40, 41, 42; range 0-18): Evaluates repetitive thoughts, compulsive behaviours, and ritualistic actions. This includes checking behaviours, unwanted intrusive thoughts, and the need to do certain things in a particular way.
• Panic/agoraphobia (items 13, 21, 28, 30, 32, 34, 36, 37, 39; range 0-27): Assesses physical symptoms of anxiety and fear of public places or situations where escape might be difficult. This includes symptoms like heart racing, difficulty breathing, and fear of crowded places.
• Physical Injury (items 2, 18, 23, 25, 33; range 0-15): Measures specific fears related to physical harm or injury. This includes fears of doctors/dentists, fear of heights, darkness, and specific situations that might result in physical harm.
• Generalised anxiety (items 1, 3, 4, 20, 22, 24; range 0-18): Evaluates excessive worry about everyday matters, perfectionism, and general anxiety symptoms. This includes worrying about things in general, feeling nervous, and having trouble relaxing.

Items 11, 17, 26, 31, 38, 43, are positively worded filler items and are not scored in either the total score or the sub-scale scores, nor are items 45 and 46 which may elicit additional qualitative information.

A descriptor is determined that is based upon the percentiles:

• Normal: Percentile of 84 or less
• Elevated: Percentile of 85 or above and less than or equal to 93
• High: Percentile of 94 or above and less than or equal to 97.72
• Very High: percentile of 97.73 or greater

On first administration a stacked bar graph is presented showing the percentiles for the total score and subscales with the descriptors in the background of the plot. If the scale is administered on multiple occasions a graph is produced to track symptoms over time for both the total and the subscale percentiles.

A reliable change score for the total score was determined by NovoPsych based upon 7,240 administrations of the SCAS-Child. The reliable change score was calculated as 14, meaning that if a client demonstrates a reduction of 14 points or more on the SCAS-Child total score then they have demonstrated significant improvement in their anxiety symptoms. Similarly, if they have demonstrated an increase of 14 points or more then this indicates a significant deterioration in their anxiety symptoms.

• Normal: Percentile of 84 or less (equivalent to T scores of 60 and below)
• Elevated: Percentile of 85 or above and less than or equal to 93 (equivalent to T scores of between 61 and 64)
• High: Percentile of 94 or above and less than or equal to 97.72 (equivalent to T scores of between 65 and 69)
• Very High: percentile of 97.73 or greater (equivalent to T scores of 70 and above)
