“…Such sentiments have also been well articulated within the stress-coping (Wills & Shiffman, 1985) and self-medication models (Khantzian, 1997) of substance use. Consistent with these conceptualizations, a large literature on smoking motives (Shiffman, 1993) and smoking expectancies (Brandon, Juliano, & Copeland, 1999) reliably demonstrates that the majority of adult smokers attribute their smoking to its reputed ability to calm them when stressed and, more generally, reduce NA (e.g., Ikard, Green, & Horn, 1969;McKennell, 1970;Spielberger, 1986; see Kassel, Stroud, & Paronis, 2003). Thus, smoking as an anxiolytic tool emerges as the most widely endorsed motive among adult smokers, particularly among those who are nicotine dependent (Shiffman, 1993).…”
