For this study, we developed and evaluated the psychometric properties of the Primary Appraisal of Smoking Cessation Inventory (PASCI), a self-report measure designed to assess the perceived gains and losses associated with quitting smoking based on the theoretical model of stress described by Lazarus and Folkman (1984). We administered the 26-item PASCI and two other questionnaires to 244 current smokers and to 30 ex-smokers. Item analyses indicated that two items on the PASCI should be deleted due to low item-total correlations. A principal components analysis of the remaining 24 items identified two separate and independent factors, Losses and Gains, and scores on the subscales of both factors were internally consistent and stable over repeated administrations. The validity of the PASCI was established by examining the relationship between smoking status and scores on the PASCI subscales and by finding significant correlations between the PASCI and the Decisional Balance Scale (Velicer, DiClemente, Prochaska, & Brandenburg, 1985), a measure conceptually similar to the construct measured by the PASCI. We concluded that the PASCI is reliable and valid and can be used to investigate the relationship between primary appraisal and smoking cessation.
在本研究中，我们开发并评估了戒烟初始评估量表（PASCI）的心理测量特性。该量表为自陈式量表，旨在基于拉扎勒斯和福克曼（1984年）描述的压力理论模型，评估与戒烟相关的感知收益和损失。我们对244名当前吸烟者和30名已戒烟者施测了包含26个条目的PASCI以及另外两份问卷。项目分析表明，由于项目与总分的相关性较低，PASCI中的两个条目应予以删除。对其余24个条目的主成分分析确定了两个独立的因素，即损失和收益，且两个因素分量表的得分在重复施测中具有内部一致性和稳定性。通过检验吸烟状况与PASCI分量表得分之间的关系，以及发现PASCI与决策平衡量表（维利泽、迪克莱门特、普罗查斯卡和勃兰登堡，1985年）之间的显著相关性，确立了PASCI的效度。决策平衡量表在概念上与PASCI所测量的结构相似。我们得出结论，PASCI是可靠且有效的，可用于研究初始评估与戒烟之间的关系。
