AIMS
To test internal consistency and factor structure of a brief instrument called Trying to Quit smoking.
BACKGROUND
The most effective treatment for patients with chronic obstructive pulmonary disease is to quit smoking. Constant thoughts about quitting and repeated quit attempts can generate destructive feelings and make it more difficult to quit.
DESIGN
Development and psychometric testing of the Trying to Quit smoking scale.
METHODS
The Trying to Quit smoking, an instrument designed to assess pressure-filled states of mind and corresponding pressure-relief strategies, was tested among 63 Swedish patients with chronic obstructive pulmonary disease. Among these, the psychometric properties of the instrument were analysed by Exploratory Factor Analyses.
RESULTS
Fourteen items were included in the factor analyses, loading on three factors labelled: (1) development of pressure-filled mental states; (2) use of destructive pressure-relief strategies; and (3) ambivalent thoughts when trying to quit smoking. These three factors accounted for more than 80% of the variance, performed well on the Kaiser-Meyer-Olkin (KMO) test and had high internal consistency.
目的
测试一种名为“尝试戒烟”的简短工具的内部一致性和因子结构。
背景
慢性阻塞性肺疾病患者最有效的治疗方法是戒烟。持续的戒烟念头和反复的戒烟尝试会产生破坏性情绪，使戒烟更加困难。
设计
“尝试戒烟”量表的开发与心理测量测试。
方法
“尝试戒烟”这一旨在评估充满压力的心理状态及相应减压策略的工具，在63名瑞典慢性阻塞性肺疾病患者中进行了测试。其中，通过探索性因子分析对该工具的心理测量特性进行了分析。
结果
因子分析纳入了14个项目，这些项目加载在三个因子上，分别为：（1）充满压力的心理状态的形成；（2）使用破坏性减压策略；（3）尝试戒烟时的矛盾想法。这三个因子解释了超过80%的方差变异，在凯泽 - 迈耶 - 奥尔金（KMO）检验中表现良好，且具有较高的内部一致性。
