g., depression) (Watson et al., 1995). The Cronbach��s �� in this sample was .83. The Center for Epidemiologic Studies Depression Scale The Center for Epidemiologic Studies Depression Scale (CESD) is a 20-item they self-report scale that measures past-week depressive symptomatology for general population samples and has shown good psychometric properties (Radloff, 1977; Shafer, 2006). Experimental Session Measures Positive and Negative Affect Schedule The PANAS (Watson, Clark, & Tellegen, 1988) assesses positive affect (10 items, e.g., enthusiastic, strong; Cronbach��s �� for change [post-cigarette �C pre-cigarette] = .62) and negative affect (10 items, e.g., distressed, upset; �� change = .66). Participants were instructed to respond based on how they feel ��right now�� on a scale ranging from 1 (not at all) to 5 (extremely).
Tobacco Craving Questionnaire��Short Form The TCQ is a 12-item questionnaire that measures tobacco craving via four subscales: (a) emotionality��smoking to avoid negative affect (�� change = .77); (b) expectancy��smoking in anticipation of positive affect (�� change = .89); (c) compulsivity��inability to regulate tobacco intake (�� change = .63); (d) purposefulness��motivated decisiveness to smoke for positive effects (�� change = .54; Heishman, Singleton, & Pickworth, 2008). Participants were instructed to respond based on how they feel ��right now�� on a Likert-type scale ranging from 1 (strongly disagree) to 7 (strongly agree). The TCQ��s internal consistency, criterion validity, and factorial validity have been supported in prior work (Heishman et al.
, 2008). Cigarette Evaluation Questionnaire The CEQ is a self-report measure of the acute effects of smoking that includes five subscales: smoking satisfaction (two items: ��Was it satisfying?�� ��Did it taste good?��; �� = .86); psychological reward (five items: ��Did it calm you down?�� ��Help you concentrate?�� ��Make you feel more awake?�� ��Reduce hunger?�� ��Make you feel less irritable?��; �� = .88); aversion (two items: ��Make you nauseated?�� ��Make you dizzy?��; �� = .53); enjoyment of sensations in the respiratory tract (one item), and craving reduction (one item; Westman, Levin, & Rose, 1992). Responses were provided on a visual analog 100-mm scale, and participants were instructed to rate effects from the cigarette they just smoked. Psychometric properties of the CEQ including the factorial validity of its subscales have AV-951 been previously established (Cappelleri et al., 2007). Statistical Analysis Following calculation of descriptive statistics, all variables were checked for normality, and transformations to approximate normality were applied when appropriate.
