Note. Demographic and smoking characteristics of study completers (N = 47) at intake shown as percentages or group averages (SD). minimum and maximum range values are also shown for carbon monoxide (CO) and urinary cotinine (COT) following SD values. Fisher’s exact test was used for gender and ethnicity variables, while the Mann–Whitney Rank Sum Test was used for nonnormally distributed values found for CO and urinary COT. All other variables were analyzed with the use of t tests.
SCL-90 = Symptoms Checklist-90; BDI = Beck Depression Inventory.
