儿童白血病具有自然病程短、病情变化复杂、并发症多及治疗费用高等特点。患儿一旦确诊，其家长即面临患儿生命受到威胁和经济等方面的多重压力，而家长的负性情绪会进一步影响患儿情绪和生活质量，从而造成恶性循环。近年来，白血病患儿长期生存率已经达到70%~90%，大量白血病患儿及其家长将带着白血病诊断带来的影响投入到平常的生活当中去，因此，通过干预帮助家长在患儿确诊后更好地应对创伤并带着希望继续生活至关重要。

为此，本研究采用个案研究的方法，使用THRIVE模型对白血病患儿家长进行干预，以提升白血病患儿家长的PTG，降低其创伤后应激症状（Posttraumatic Stress Symptoms, PTSS）。THRIVE模型是一种干预框架，以创伤后成长（Posttraumatic Growth, PTG）的情感-认知加工模型为依据，旨在帮助个体在经历创伤性事件后，通过六个关键步骤走向心理复原和PTG。

考虑到来访者遇到的困境与创伤程度不同，咨询师与三位来访者分别工作了10次、11次和12次。本研究中采用的方案以THRIVE模型为基础，结合白血病患儿家长的特点制定，共分为五个阶段：第一阶段，初始评估（1~3次不等）；第二阶段，自我觉察与直面创伤（2~3次不等）；第三阶段，孕育希望（2~3次不等）；第四阶段，发现及评估变化（1~2次不等）；第五阶段，结束阶段（1~2次不等）。使用创伤后应激障碍自评量表（第5版）、焦虑自评量表、抑郁症筛查量表、创伤后心理健康变化问卷、简体中文版创伤后成长量表对来访者进行前、后测；使用焦虑自评量表和抑郁症筛查量表对来访者进行每隔一周的测试，以监控个体精神健康情况，筛查是否存在转介需要；使用创伤后心理健康变化问卷对来访者进行每隔一周的测试，以观测其在创伤后幸福感方面的变化。

结果发现，经过干预后，三位来访者均获得了更高水平的PTG，而其PTSS、抑郁水平及焦虑水平均有不同程度的降低；对三位来访者的半结构化访谈表明，咨询中的共情、压力泡泡图、改写故事、感恩练习、盘点创伤后心理健康变化、帮助其发现及评估变化，均不同程度对其产生了启发与效果。

总之，本研究的结果支持THRIVE模型对白血病患儿家长的干预效果，如降低来访者的PTSS、抑郁和焦虑水平，提升其PTG。研究表明，基于THRIVE模型对白血病患儿家长制定的特定干预方案，有一定的适用性与可行性。

Due to the short natural course, unstable condition of disease, complex complications and high treatment costs, the diagnosis of childhood leukemia means children's lives are threatened and the family is facing with economic pressures to the parents. The negative emotions of the parents will affect the child's mood and quality of life thus causing a vicious circle. In recent years, the long-term survival rate of children with leukemia has reached 70%~90%. A large number of children with leukemia and their parents will return to their life with the impact of leukemia diagnosis. It is crucial to help parents better cope with the trauma and continue to live with hope through intervention.

Therefore, this case study explored the feasibility potential of using the THRIVE model in perspective of the Posttraumatic Growth(PTG) to enhance the PTG and decrease Posttraumatic Stress Symptoms(PTSS) of parents whose children diagnosed with leukemia. The THRIVE model is an intervention framework based on the affective-cognitive processing model of posttraumatic growth(PTG), aiming to help individuals achieve psychological recovery and PTG through six steps after experiencing a traumatic event.

Considering that the dilemma and trauma encountered by the clients were different, the consultant worked with three different clients for 10,11, and 12 times respectively. A specific intervention scheme based on the characteristics of the parents of children with leukemia was used in this intervention. The intervention scheme was divided into five stages: the first stage, initial assessment(1~3 times); the second stage, self-awareness and face up to trauma(2~3 times); the third stage, harvesting hope(2~3 times); the fourth stage, finding and evaluating changes(1~2 times), the fifth stage, the end stage(1~2 times). Clients were tested before and after the intervention using the Chinese-Posttraumatic Growth Inventory(C-PTGI), Psychological Well-Being—Post-Traumatic Changes Questionnaire(PWB-PTCQ), Patient Health Questionnaire-9(PHQ-9), PTSD Checklist-Civilian Version(PCL-C) and Self-Rating Anxiety Scale(SAS). The SAS and PHQ-9 were used every other week during the intervention to monitor individual’s mental health for referral possibility and the PWB-PTCQ was used to observe changes in posttraumatic well-being.

The results showed that after the intervention, three clients had a higher level of PTG. Clients’ PTSS, depression and anxiety level had all decreased. The conclusion of semi-structured interviews showed that clients were inspired by the empathy, pressure bubble chart, story rewriting, gratitude practice, and the PWB-PTCQ trend discovery.

In conclusion, the result of the study support that the THRIVE model has a good intervention effect on the trauma of parents of children with leukemia. The intervention improved clients’ PTG, reduced clients’ PTSS, level of depression and anxiety. The study shows the applicability and feasibility of the specific intervention program based on THRIVE model for parents of children with leukemia.
