Research on the Application of Decision Tree in Child Life

Before and after each intervention, researchers collected on-site the clinical anxiety and cooperative behavior manifestations of the children included in the intervention plan. The scoring range of this scale is from 0 to 5, with a total of six points. A score of 0 indicates ease, 1 indicates discomfort, 2 indicates tension, 3 indicates reluctance, 4 indicates fear, and 5 indicates loss of control. The higher the score, the more resistant the child is to treatment and the poorer the degree of cooperation. It is generally believed that children with a score of 4 or 5 are unable to cooperate with the treatment.

This questionnaire is derived from the ACLP Child Life Specialists(CLS) Knowledge Question Bank, aiming to assist the CLS system in mastering the psychological support, developmental-appropriate care, and service skills required by the profession. In this study, 25 questions were randomly selected from the total question bank to form an online questionnaire. The total score of the questionnaire is set at 100 points, with 4 points assigned to each question, which is used to test the knowledge level of CLS.

The content of this questionnaire is based on the ability evaluation list of Child Life Specialists provided by St. Jude Children's Hospital in the United States. It is based on six dimensions: assessment, games, psychological preparation, procedural support, medical education, and family support. Two CCLS who have been trained and certified by the ACLP system are respectively evaluated for their performance in all modules, professional spirit, and overall practical performance. Provide a summary comment and final rating, which are classified into four categories: poor, average, good, and very good.

To comprehensively and objectively assess the ability level of Child Life Specialists(CLS) in clinical practice, the research team, based on Dreyfus' skill acquisition model, divided the professional ability of CLS into four consecutive development stages: novice level, advanced beginner level, competent level and proficient level. Cross-validation through simultaneous evaluation by two CCLS is conducted to truly reflect the professional maturity of CLS in complex clinical contexts.

FACES Pain Scale in this study was only conducted in specific clinical situations that might cause pain in the children. Specifically, the children patients will be independently evaluated by two trained researchers to ensure the reliability and accuracy of the scores. During this assessment process, researchers comprehensively judged the degree of pain of the children based on their behavioral responses and verbal expressions, and marked the corresponding scores on the visual analogue scale.
