Overview
The CAMP is a unidimensional 8-item parent-report measure designed to assess a child’s tendency to avoid anxiety-provoking situations. The CAMP is designed to be applicable to the full spectrum of anxiety disorders in children and adolescents.Scoring & Interpretation
Items are rated on a 4-point response scale ranging from 0 (never) to 3 (almost always). Total scores are a sum of all 8 items and range from 0 to 24. Scores range between 0 and 24, with higher scores indicating greater behaviour avoidance.Psychometric Properties
Internal Consistency
In the original development research internal consistency was excellent: α = .90 in the community sample α .91 in the clinical sample (Whiteside et al., 2013).
Test-Retest Reliability
Test-retest in the community sample was.75
Factor Structure
Over a series of three studies including exploratory factor analysis and confirmatory factor analysis, and including both a community and clinical sample the CAMP demonstrated a uni-dimensional structure, with all 8-items loading onto a single factor.
Validity
Concurrent validity was examined through correlations with measures of anxiety and disability (Spence Children’s Anxiety Scale; Social Anxiety Scale for Children-Revised; Fear of Negative Evaluations; Child Sheehan Disability Scale; Social Avoidance and Distress).
Criterion validity was assessed through group differences between subgroups of the clinical and community samples matched on age and sex. Clinical sample scores indicated significantly more avoidance than in the community sample. Group differences on the anxiety measures suggest that the groups differed as expected on clinical variables.
Measurement Invariance
Invariance testing to examine whether the measurement model of the CAMP was consistent across age (i.e., above and below 12.5 years) found that the CAMP was age invariant.
