The effectiveness of a paediatric pain management programme was examined using a multiple case study design. This study examined both the children's pain experience during cancer treatment, as well as their parents’anxiety and behavioural stress. Fourteen people were videotaped while receiving lumbar punctures during an 8–12 month period. Baseline data were obtained at the first of three visits prior to the introduction of relaxation, imagery and distraction exercises. Self‐ratings of child fear and parent anxiety, videotaped observations of child and parent behaviour and child pain ratings were obtained at all three visits. The children's behavioural responses to the procedure varied considerably, but their fear scores were stable and their reports of pain decreased over time. Parents reported high‐trait, low‐state anxiety scores that were stable over time. They were observed to be very supportive during the procedures. Implications for further research in this area and recommendations for practice are
