This study explored whether the structure of negative affect in children is similar to that previously found in adults (S. H. Lovibond & P. F. Lovibond, 1995). A sample of 577 7–14-year-old children completed a 76-item questionnaire designed to measure anxiety, depression, and tension/stress, comprising both exploratory items and the full item content of established measures of childhood anxiety and depression. Exploratory factor analyses indicated that several symptoms that were previously found to be nonspecific in adults also failed to differentiate between anxiety and depression in youth. Further, the core symptoms of depression were shown to be similar to those previously identified in adults. However, the hypothetical constructs of anxiety and tension/stress could not be differentiated. It is possible that these two distinct affective syndromes have not yet emerged in childhood. Alternatively, future refinements of the questionnaire's item content may lead to a more precise assessment of anxiety and tension/stress in children.
