ABSTRACT This study examines differences in smoking behaviors between adults with and without serious psychological distress (SPD) in California, which has the longest running comprehensive tobacco control program in the world.
Cross-sectional data from the 2007 California Health Interview Survey on 50,880 noninstitutionalized adults were used to analyze smoking prevalence, cigarette consumption, and quit ratio. Persons with SPD were identified using the K6 scale, a clinically validated psychological screening instrument.
About 3.8% of California adults screened positive for SPD in the past 30 days (acute SPD) and an additional 4.8% screened positive for SPD in the past 2-12 months (recent SPD). Persons with SPD were more likely to be current smokers than those without SPD (adjusted odds ratios [AOR] = 2.54, 95% CI = 2.02-3.19 for acute SPD and AOR = 2.20, 95% CI = 1.79-2.71 for recent SPD). Current smokers with acute SPD were more likely to smoke ≥20 cigarettes daily than those without SPD (AOR = 1.59, 95% CI = 1.06-2.39). The quit rate was lower among ever-smokers with acute (AOR = 0.46, 95% CI = 0.35-0.62) or recent SPD (AOR = 0.55, 95% CI = 0.42-0.71) than those without SPD. While persons with acute or recent SPD comprised 8.6% of adults, they consumed 19.2% of all cigarettes in California.
In California, adults with SPD were more likely to be current smokers and to smoke heavily and less likely to quit than those without SPD. The findings underscore the need for effective smoking cessation strategies targeting this group.

    ABSTRACT: Using data from annual (2004-2010) cross-sectional surveys of nationally representative samples, the prevalence rate of current (i.e., past 30 days) cigarette smoking among US adolescents age 12-17 years was twice as high for those with vs. without a past-year major depressive episode (PYMDE) (22 vs. 11 % in the 2004 survey and 16 vs. 8 % in the 2010 survey). The proportion of all US adolescent current smokers who had a PYMDE was about 24 % for females; 70-80 % of all smokers with PYMDE were females. The persistently higher smoking rates in US adolescents with vs. without PYMDE emphasizes the need for interventions.

    ABSTRACT: Cigarette smoking among persons living with HIV (PLWH) is a pressing public health concern, and efforts to evaluate cessation treatments are needed. The purpose of the present study was to assess potential mechanisms of a cell phone-delivered intervention for HIV-positive smokers. Data from 350 PLWH enrolled in a randomized smoking cessation treatment trial were utilized. Participants were randomized to either usual care (UC) or a cell phone intervention (CPI) group. The independent variable of interest was treatment group membership, while the dependent variable of interest was smoking abstinence at a 3-month follow-up. The hypothesized treatment mechanisms were depression, anxiety, social support, quit motivation and self-efficacy change scores. Abstinence rates in the UC and CPI groups were 4.7% (8 of 172) and 15.7% (28 of 178), respectively. The CPI group (vs. UC) experienced a larger decline in depression between baseline and the 3-month follow-up, and a decline in anxiety. Self-efficacy increased for the CPI group and declined for the UC group. Quit motivation and social support change scores did not differ by treatment group. Only self-efficacy met the predefined criteria for mediation. The effect of the cell phone intervention on smoking abstinence through change in self-efficacy was statistically significant (p<0.001) and accounted for 17% of the total effect of the intervention on abstinence. The findings further emphasize the important mechanistic function of self-efficacy in promoting smoking cessation for PLWH. Additional efforts are required to disentangle the relationships between emotional, distress motivation, and efficacious smoking cessation treatment. Copyright © 2014 Elsevier Ireland Ltd.
