Pediatric Procedural Approach-Avoidance Coping and Distress: A Multitrait-Multimethod Analysis

OBJECTIVE: To evaluate the construct validity of children's approach-avoidance coping and distress during immunizations, and to examine the instruments used to assess these domains. METHODS: We used a multitrait-multimethod matrix to examine the validity of the approach-avoidance coping and distress constructs for 62 4- to 6-year-old children receiving immunization injections. Assessment instruments of both constructs consisted of child, parent, and nurse ratings, and three behavior observation scales. RESULTS: Pediatric procedural distress demonstrated adequate convergent and discriminant validity, and it can be assessed in a valid manner. Whereas most approach-avoidance measures demonstrated good convergent validity, several measures did not adequately distinguish between avoidance and distress. CONCLUSIONS: It is possible that children's approach-avoidance coping may be qualitatively different than adult's approach-avoidance. Researchers should be cognizant of these differences when designing treatments for child procedural distress.
