The State-Trait Anxiety Inventory for Children (STAIC) was initially developed as a research tool for the study of anxiety in elementary school children. It is comprised of separate, self-report scales for measuring two distinct anxiety concepts: state anxiety (S-Anxiety) and trait anxiety (T-Anxiety).
The S-Anxiety scale is designed to measure transitory anxiety states, that is, subjective, consciously perceived feelings of apprehension, tension, and worry that vary in intensity and fluctuate over time. The T-Anxiety scale measures relatively stable individual differences in anxiety proneness, that is, differences between children in the tendency to experience anxiety states.
The STAIC T-Anxiety scale may be used for research purposes to select children who vary in anxiety proneness or as an experimental screening device for detecting neurotic behavioral tendencies in elementary school children. The T-Anxiety scale should also prove useful as a measure of the effectiveness of clinical treatment procedures designed to reduce neurotic anxiety in children.
