Objective:To investigate the effect of attention and interpretation therapy on posttraumatic stress disorder and perceived stress of parents with children having developmental dislocation of the hip.Methods:Totally 96 parents with children having developmental dislocation of the hip from women and children hospital of Hubei province were divided into experimental group ( n=46) and control group ( n=46) according to the random number table method. The control group received routine postoperative DDH care. On the basis of this, the experimental group was given attention and interpretation therapy for 8 weeks. Before intervention and at the end of intervention, the effects were assessed by Posttraumatic Stress Checklist-Civilian Version (PCL-C) and Chinese Perceived Stress Scale (CPSS). Results:After intervention, the scores of arousal symptoms, avoidance/numbing, re-experiencing symptoms and total PCL-C scores were 8.47±2.30, 10.67±2.67, 7.49±2.63, 26.62±4.10, in addition, the scores of sense of tension, sense of out of control and total scores of CPSS were 11.71±2.21, 11.27±2.95, 22.98±3.77, which were significantly lower than those in the control group (9.45±2.33, 12.39±2.43, 8.93±2.79, 30.77±5.30, 12.86±3.05, 13.09±3.46, 25.95±4.52), the difference was statistically significant ( t value was 2.013-4.135, P<0.05). Conclusion:Attention and interpretation therapy can effectively relieve posttraumatic stress disorder symptom and alleviate perceived stress level of parents with children having developmental dislocation of the hip.
