A randomised control study of a fully automated internet based smoking cessation programme.

OBJECTIVE: The objective of this project was to test the short term (90 days) efficacy of an automated behavioural intervention for smoking cessation, the "1-2-3 Smokefree" programme, delivered via an internet website. DESIGN: Randomised control trial. Subjects surveyed at baseline, immediately post-intervention, and 90 days later. SETTINGS: The study and the intervention occurred entirely via the internet site. Subjects were recruited primarily via worksites, which referred potential subjects to the website. SUBJECTS: The 351 qualifying subjects were notified of the study via their worksite and required to have internet access. Additionally, subjects were required to be over 18 years of age, smoke cigarettes, and be interested in quitting smoking in the next 30 days. Eligible subjects were randomly assigned individually to treatment or control condition by computer algorithm. INTERVENTION: The intervention consisted of a video based internet site that presented current strategies for smoking cessation and motivational materials tailored to the user's race/ethnicity, sex, and age. Control subjects received nothing for 90 days and were then allowed access to the programme. MAIN OUTCOME MEASURES: The primary outcome measure was abstinence from smoking at 90 day follow up. RESULTS: At follow up, the cessation rate at 90 days was 24.1% (n = 21) for the treatment group and 8.2% (n = 9) for the control group (p = 0.002). Using an intent-to-treat model, 12.3% (n = 21) of the treatment group were abstinent, compared to 5.0% (n = 9) in the control group (p = 0.015). CONCLUSIONS: These evaluation results suggest that a smoking cessation programme, with at least short term efficacy, can be successfully delivered via the internet.

Relationship of sexual orientation to substance use, suicidal ideation, suicide attempts, and other factors in a population of homeless adolescents.

PURPOSE: To explore the relationship of sexual orientation and gender to four sets of factors: (a) family history, (b) incarceration, (c) substance use, and (d) depression and suicide, in a population of homeless adolescents. METHODS: A sample of homeless adolescents was recruited in Portland, Oregon and assessed using semi-structured interviews at baseline, three months and six months. A total of 532 youths (216 females and 316 males) provided data on sexual orientation and other variables. Heterosexual (n = 391) and non-heterosexual youths (n = 141) were compared on all sets of factors, primarily using logistic regressions. RESULTS: 44.9% of females identified as lesbian or bisexual, while only 13.9% of males identified as gay or bisexual. Gay, lesbian, bisexual, and "unsure" (GLBU) youths were less likely to have been in foster care or arrested, but were more likely to have spent time in a locked mental health treatment facility. More than one-third of all participants reported use of injection drugs. GLBU youths were more likely to have recently used amphetamines and to have injected drugs, however, gay-bisexual males were less likely to have recently used marijuana. GLBU status was associated with recent measures of depression and suicidal ideation, but not with lifetime measures. Associations of sexual orientation with several lifetime measures were different than with prospective measures, demonstrating the limitations of using lifetime measures rather than recent or prospective measures. CONCLUSIONS: This population of homeless adolescents appears to be higher in its high rate of injection drug use and the large proportion of females who identify as lesbian or bisexual than found in other studies. The high rates of depression and suicidal ideation, especially among GLBU youth, are of great concern.

Development of adolescent problem behavior.

The developmental model of adolescent antisocial behavior advanced by Patterson and colleagues (e.g., Patterson, Reid, & Dishion, 1992) appears to generalize the development of a diverse set of problem behaviors. Structural equation modeling methods were applied to 18-month longitudinal data from 523 adolescents. The problem behavior construct included substance use, antisocial behavior, academic failure, and risky sexual behavior. Families with high levels of conflict were less likely to have high levels of parent-child involvement. Such family conditions resulted in less adequate parental monitoring of adolescent behavior, making associations with deviant peers more likely. Poor parental monitoring and associations with deviant peers were strong predictors of engagement in problem behavior. These constructs accounted for 46% of the variance in problem behavior. Although association with deviant peers was the most proximal social influence on problem behavior, parental monitoring and family factors (conflict and involvement) were key parenting practices that influenced this developmental process.

A brief office-based intervention to facilitate diabetes dietary self-management.

There is a pressing need for brief, practical interventions that address diabetes management. We have developed an office-based intervention to prompt both patients and providers to focus on behavioral issues relevant to dietary self-management that is being evaluated in a randomized trial. The intervention is designed to be broadly applicable to the majority of adult diabetes outpatients during medical visits; uses touchscreen computer assessment to provide immediate feedback on key issues to patients and providers just prior to their interaction; and provides goal setting and problem-solving assistance to patients following their meeting with the physician. Follow-up components include phone calls and videotape or interactive video instruction as needed. The program is described, and demographic and behavioral characteristics of participants are presented for the first 95 patients randomized. Initial process results suggest success in producing modest, targeted behavior changes among a broad cross-section of patients. If the long-term results are equally positive, this intervention could provide a prototype for a feasible, cost-effective way to integrate patient views and behavioral management into office-based care for diabetes.
