背景　戒斷症狀是尼古丁依賴非常重要的一個特性，一個有信效度的戒斷症狀測量工具對於了解吸菸者尼古丁依賴及發展介入治療非常有助益。目的　本研究之目的為檢測中文版吸菸戒斷症狀量表的心理計量特性。方法　本研究設計採二階段的橫斷性調查，第一階段包括探索量表的結構因素、測試效標關聯效度和信度（內在一致信及穩定度）。第二階段則驗證第一階段所得的因素結構模式，總樣本數是497。結果　中文版吸菸戒斷症 狀量表與英文版相似，具有六個因素，其解釋變異量達80.3%，大多數的次量表與尼古丁依賴量表達顯著正相關（r = .25– .50, p ＜ .05），除了體重—食慾這個次量表（r = .12, p = .09）。內在一致性（Cronbach’s alpha）.93，二週再測穩定性為.84。驗證性因素分析結果確立中文版吸菸戒斷狀量表是一個具有六個相關因素的結構模式。結論／實務應用　本研究結果顯示中文版吸菸戒斷症狀量表具有良好的信、效度。護理人員可以運用此量表評估吸菸者戒斷症狀情形，並且依評估內容進行適當的戒斷治療。

Background: Symptoms of smoking withdrawal are a central feature of nicotine dependence. A valid and reliable measure of these symptoms is important to better understand nicotine dependence and to develop effective interventions. Purpose: The objective of this study was to examine the validity and reliability of the Chinese version of the CigaretteWithdrawal Scale (CWS-C). Methods: This study conducted cross-sectional surveys in two phases. In the first phase, exploratory factor analysis was used to test the underlying factor structure, the criterion validity, and the reliability of the CWS-C. A reliability test was conducted to assess the internal consistency and stability of the instrument. In the second phase, confirmatory factor analysis validated the factor model that had been proposed in earlier empirical research. The total sample size used in analysis was 497. Results: The CWS-C achieved a level of efficacy that was similar to the English version. Exploratory factor analysis showed that the six factors of the instrument accounted for 80.3% of the variance. The full scale and all of the subscale items, with the exception of the appetiteYweight gain subscale (r = .12, p = .09), were significantly associated with the Fagerstrom Test for Nicotine Dependence (r = .25-.50, p ＜ .05). The Cronbach’s alpha of the full scalewas .93, with retest coefficient of .84. Confirmatory factor analysis confirmed that the CWS-C had six correlated factors. Field testing showed that the CWS-C is a reliable and valid Chinese-language instrument for assessing the symptoms of cigarette withdrawal. Conclusions/Implications for Practice: TheCWS-C performed well in terms of reliability and validity in several tests conducted on male Taiwanese smokers. Accurate measurement is expected to help health professionals better understand smoker quitting patterns and the severity ofwithdrawal symptoms and to develop improved withdrawal-symptom treatment interventions.
