Toward evidence-based Internet interventions: A Spanish/English Web site for international smoking cessation trials.
The Internet provides a medium to administer and evaluate evidence-based interventions for highly prevalent public health problems worldwide. The authors report a series of four Internet smoking cessation studies conducted in English and Spanish. These studies examined both outcome (self-reported 7-day abstinence) and mechanisms related to outcome (the impact of major depressive episodes [MDEs] on the likelihood of quitting). Over 4,000 smokers from 74 countries entered the studies. Studies 1 and 2 evaluated a standard smoking cessation guide (the "Guía"). Studies 3 and 4 were randomized trials comparing the Guía+ITEMs (individually timed educational messages) to the Guía+ITEMs+a mood management course. ITEMs were E-mails inviting participants back to the site at specific times. Online follow-up assessments resulted in completion rates of 44%-54% at 1 month and 26%-30% at 6 months in studies 1 and 2. Incentives and follow-up phone calls increased these rates to 70%, 66%, 65%, and 62% at 1, 3, 6, and 12 months in study 4. At 6 months, self-reported 7-day abstinence rates using missing = smoking data were 6% in studies 1 and 2, 10%-14% in study 3, and 20%-26% in study 4. The Guía+ITEMs condition tended to have higher quit rates, which reached significance at the 12-month follow-up in study 3 and at the 3-month follow-up in study 4. Smokers with past (but not current) MDEs tended to be the most likely to abstain and those with current MDEs the least likely. This trend reached significance in studies 1 and 4.

Toward evidence-based interventions for diverse populations: The San Francisco General Hospital prevention and treatment manuals.
Clinical trials have seldom included adequate samples of people of color. Therefore, practitioners serving ethnic minorities often do not have access to readily available evidence-based interventions. This article summarizes the development and empirical evaluation of prevention and treatment manuals designed for low-income ethnic minority populations at San Francisco General Hospital. The manuals were often designed by people of color familiar with the communities for which they were developed. Independent research teams in multi-site national and international clinical trials have evaluated many of these manuals with encouraging results.

Automated e-mail messaging as a tool for improving quit rates in an internet smoking cessation intervention.
OBJECTIVE: The aim of this study was to determine whether an automated e-mail messaging system that sent individually timed educational messages (ITEMs) increased the effectiveness of an Internet smoking cessation intervention. DESIGN: Using two consecutive series of participants, the authors compared two Web-based self-help style smoking cessation interventions: a single-point-in-time educational intervention and an enhanced intervention that also sent ITEMs timed to participants' quit efforts. Outcomes were compared in 199 participants receiving the one-time intervention and 286 receiving ITEMs. MEASUREMENTS: Demographic factors, number of cigarettes smoked, nicotine addiction, depressive symptoms, and confidence in ability to quit were measured at entry. Twenty-four-hour quit attempts and seven-day point-prevalence of abstinence (nonrespondents assumed to smoke) were measured 30 days after each subject's self-selected quit date. RESULTS: The one-time and ITEMs groups differed in some demographics and some relapse risk factors but not in factors associated with 30-day quit rates. ITEMs appeared to increase the rate at which individuals set quit dates (97% vs. 91%, p = 0.005) and, among the respondents to follow-up questionnaires (n = 145), the rate of reported 24-hour quit efforts (83% vs. 54%, p = 0.001). The 30-day intent-to-treat quit rates were higher in the ITEMs group: 7.5% vs. 13.6%, p = 0.035. In multivariate analyses controlling for differences between groups, receiving ITEMs was associated with an increase in the odds ratio for quitting of 2.6 (95% confidence interval = 1.3-5.3). CONCLUSION: ITEMs sent on strategic days in smokers' quit efforts enhanced early success with smoking cessation relative to a single-point-in-time Web intervention. The effect appears to be mediated by ITEMs' causing smokers to plan and undertake quit efforts more frequently.

Impact of stress reduction instructions on stress and cortisol levels during pregnancy.
This pilot study examined whether giving stress reduction (SR) instructions to pregnant women would be effective in regulating stress, mood, and cortisol levels during pregnancy. Forty-one predominantly low-income Latina women, receiving prenatal services at a public county hospital, completed measures of stress and mood (depressive symptoms, positive and negative affect) and provided morning and evening saliva samples to measure cortisol prior to and after receiving SR instructions. We hypothesized that adherence to these SR instructions would result in lower levels of stress, negative mood states, and cortisol levels when compared to baseline values. Repeated measures ANOVA analyses demonstrated significantly lower levels of stress (P < 0.001), lower symptoms of depression and negative affect (P < 0.001), and lower levels of morning cortisol (P = 0.01) under the SR condition, compared to baseline. Health behaviors that were engaged in during the SR condition and implications for prenatal health interventions are discussed.

Influences of mood, depression history, and treatment modality on outcomes in smoking cessation.
The relationship between major depressive disorder (MDD), treatment modality, and mood was evaluated in smokers participating in cessation programs. Participants (N = 549, 53.7% women, 46.3% men, 28% endorsing past MDD episodes) were randomly assigned to a cognitive-behavioral treatment (CBT) or health education (HE) intervention. Participants with a history of recurrent MDD (MDD-R) had higher rates of abstinence in CBT compared with HE even when the contribution of mood and the interaction between mood and an MDD x Treatment variable were included in the model. Likewise, higher levels of mood disturbance were reported by MDD-R smokers compared with those reporting a single episode. The study replicated results reported by R. A. Brown et al. (2001) and expanded upon them by evaluating the differential contribution of poor mood on cessation outcomes relative to MDD history.

Extended nortriptyline and psychological treatment for cigarette smoking.
OBJECTIVE: Accepted treatments for cigarette smoking rarely achieve abstinence rates of >35% at 1 year. Low rates may reflect failure to provide extended and multifocal treatment for this complex and chronic addiction. Using a chronic disease model of smoking, the authors undertook a study to determine the effects of long-term antidepressant and psychological treatment. METHOD: One hundred sixty smokers of > or =10 cigarettes/day were randomly assigned to one of four treatment conditions in a two-by-two (nortriptyline versus placebo by brief versus extended treatment) design. All subjects received 8 weeks of a transdermal nicotine patch, five group counseling sessions, and active or placebo treatment. Interventions for subjects in brief treatment ended at this point. Subjects in extended treatment continued taking drug or placebo to week 52 and received an additional 9 monthly counseling sessions, with checkup telephone calls midway through each session. Subjects were assessed at baseline and weeks 12, 24, 36, and 52. The principal outcome variables were repeated abstinence at each assessment after the first over a 1-year period and a point prevalence of 7 days of abstinence. RESULTS: At week 52, point-prevalence abstinence rates with missing subjects imputed as smokers were 30% for placebo brief treatment, 42% for placebo extended treatment, 18% for active brief treatment, and 50% for active extended treatment. With missing subjects omitted, these rates were 32%, 57%, 21%, and 56%, respectively. CONCLUSIONS: Comprehensive extended treatments that combine drug and psychological interventions can produce consistent abstinence rates that are substantially higher than those in the literature.

The effects of depression on the emotional responses of Spanish-speaking Latinas.
Emotional responses (physiology, self-report, and facial expression) of 12 depressed and 10 nondepressed Spanish-speaking Latinas during sad and amusing film clips of human and animal content were compared. Depressed Latinas demonstrated less electrodermal reactivity across all the film clips and displayed fewer social smiles during the amusing-human film clip than nondepressed Latinas. No differences emerged for cardiovascular measures, reports of emotion, or facial expressions of happiness and negative emotion. Observed differences in electrodermal reactivity are similar to results from previous studies of Anglo Americans, suggesting that reduced electrodermal activity may be linked to depression across cultures. The findings also suggest that, for Latinas, depression may selectively alter expressions that serve interpersonal functions.

Psychosocial intervention development for the prevention and treatment of depression: promoting innovation and increasing access.
Great strides have been made in developing psychosocial interventions for the treatment of depression and bipolar disorder over the last three decades, but more remains to be done. The National Institute of Mental Health Psychosocial Intervention Development Workgroup recommends three priorities for future innovation: 1) development of new and more effective interventions that address both symptom change and functional capacity, 2) development of interventions that prevent onset and recurrence of clinical episodes in at-risk populations, and 3) development of user-friendly interventions and nontraditional delivery methods to increase access to evidence-based interventions. In each of these areas, the Workgroup recommends systematic study of the mediating mechanisms that drive the process of change and the moderators that influence their effects. This information will highlight the elements of psychosocial interventions that most contribute to the prevention and treatment of mood disorders across diagnostic groups, populations served, and community settings. The process of developing innovative interventions should have as its goal a mental health service delivery system that prevents the onset and recurrence of the mood disorders, furnishes increasingly effective treatment for those who seek it, and provides access to evidence-based psychosocial interventions via all feasible means.

Psychological intervention and antidepressant treatment in smoking cessation.
BACKGROUND: Sustained-release bupropion hydrochloride and nortriptyline hydrochloride have been shown to be efficacious in the treatment of cigarette smoking. It is not known whether psychological intervention increases the efficacy of these antidepressants. This study compared both drugs with placebo. It also examined the efficacy of these 2 drugs and placebo with and without psychological intervention. METHODS: This was a 2 (medical management vs psychological intervention) x 3 (bupropion vs nortriptyline vs placebo) randomized trial. Participants were 220 cigarette smokers. Outcome measures were biologically verified abstinence from cigarettes at weeks 12, 24, 36, and 52. RESULTS: Psychological intervention produced higher 7-day point-prevalence rates of biochemically verified abstinence than did medical management alone. With the use of point-prevalence abstinence, both nortriptyline and bupropion were more efficacious than placebo. On rates of 1-year continuous abstinence, the 2 drugs did not differ from each other or from placebo. Psychological intervention did not differ from medical management alone on rates of 1-year continuous abstinence. CONCLUSIONS: Both nortriptyline and bupropion are efficacious in producing abstinence in cigarette smokers. Similarly, psychological intervention produces better abstinence rates than simple medical management. Both drugs, and psychological intervention, have limited efficacy in producing sustained abstinence. The data also suggest that combined psychological intervention and antidepressant drug treatment may not be more effective than antidepressant drug treatment alone.

Adapted cognitive behavioral group therapy for depressed low-income African American women.
In this study we examine the degree to which a manualized cognitive-behavioral therapy intervention can be adapted to be culturally sensitive in treating depressed low-income African American women with multiple stressors. We describe the adaptations we made to an existing intervention, a group treatment developed for depressed low-income medical patients. We also describe our evaluation of the adapted treatment in which outcomes of African American women treated in the culturally adapted group were compared to African American women treated in the non-adapted group. Following treatment, women in the adapted group exhibited a larger drop in average BDI scores. Implications are discussed in terms of challenges related to the development and evaluation of culturally adapted treatment.

Design and pilot evaluation of an internet smoking cessation program.
Relatively little is known about how to use the Internet to promote health behavioral change. This article describes a multiple-contact Internet smoking cessation program with an 8-week web-based course, online tools for self-monitoring of behaviors, and computer-tailored e-mail messages timed to enrollees' quit efforts. In a pilot study in 49 smokers, we found that enrollees returned to the website a median of 2 times and completed an average of 2 of 8 educational modules. In follow-up, respondents (n = 26) rated e-mail and web components of the intervention as equally valuable (5.9 vs. 5.5 of 10, p = 0.44). While site had potentially important effects on smoking behaviors (34% of enrollees either quit smoking or had a 50% reduction in cigarette use), we were not able hold the interest of the majority of enrollees over the intervention period. Problems with the design of the site are discussed.
