Abstract
The use of pain drawings to identify the psychologic "state" of patients has been advocated. They are used for psychologic screening before considering treatments, such as surgery. For pain drawings to be clinically useful as a psychologic screen they need good positive and negative predictive values. We systematically reviewed the literature that directly compared pain drawing scoring systems with measures of psychologic state.We searched 12 medical and social science databases, using key words and their derivatives. Nineteen articles were suitable for analysis. The majority focused on low back pain (79%) in secondary or tertiary care (90%). Pain drawings were evaluated against psychologic tools testing: somatization, depression, anxiety, and distress.Three studies concluded that the association between pain drawings and psychologic state was sufficient for clinical use; of these only 1 showed reasonable sensitivity and specificity data. Six reported a statistical association and 10/19 studies reported inconclusive results and weak association. The pooled median sensitivity score was 56% (range 24% to 93%), specificity 79.5% (range 44% to 91%), positive predictive value 71.5% (range 28% to 94%), and negative predictive value 88% (range 35% to 100%). The predictive data were too low, wide-ranging, and inconsistent to accept the pain drawing as a clinical diagnostic tool to predict psychologic state.We conclude that the available data do not support the assumption that unusual pain drawings or extensive marking indicate disturbed psychologic state. There is no high quality evidence to support pain-drawing use as a psychologic assessment tool; therefore, pain drawings are not recommended for this purpose.Keywords
