The purpose of this study was to develop a scale to evaluate posttraumatic growth in patients with cancer and to examine the validity and reliability of the scale.
A literature review, semi-structured patient interviews and an expert panel consultation produced a 27 preliminary item questionnaire. Participants were 150 cancer patients recruited to test the reliability and validity of the preliminary scale. Data were analyzed using item analysis, exploratory factor analysis, convergent validity and internal consistency.
Item reduction and exploratory factor analysis led to 23 items, grouped into five subscales which were labelled new possibilities (6 items), coping skills (5 items), preciousness of life (5 items), relating to others (4 items), and personal strength (3 items). Convergent validity was evaluated by total correlation with the Functional Assessment of Cancer Therapy-General (r=.45, p<.001). The final scale demonstrated satisfactory internal consistency (Cronbach's α =.94).
Findings from this study indicate that the Cancer-Specific Posttraumatic Growth Inventory has validity and reliability and is considered to be appropriate for assessing posttraumatic growth in patients with cancer.
本研究旨在开发一种量表，用于评估癌症患者的创伤后成长，并检验该量表的有效性和可靠性。
通过文献综述、半结构化患者访谈和专家小组咨询，编制了一份包含27个初步条目的问卷。研究对象为150名招募来测试初步量表可靠性和有效性的癌症患者。使用项目分析、探索性因素分析、收敛效度和内部一致性对数据进行分析。
经过项目删减和探索性因素分析，最终得到23个条目，分为五个子量表，分别命名为新的可能性（6个条目）、应对技能（5个条目）、生命的珍贵（5个条目）、与他人的关系（4个条目）和个人力量（3个条目）。通过与癌症治疗功能评估通用量表的总相关性评估收敛效度（r = 0.45，p < 0.001）。最终量表显示出令人满意的内部一致性（Cronbach's α = 0.94）。
本研究结果表明，癌症特异性创伤后成长量表具有有效性和可靠性，被认为适合用于评估癌症患者的创伤后成长。
