Prevention profiles: Understanding youth who do not use substances.

This study replicates innovative profiles of prevention among students not using substances but who may be at different risks for acquisition. Using the Transtheoretical Model constructs of Decisional Balance and Temptations, cluster analyses were performed on four independent samples of students (n=1240) in the USA, England and Israel. For each sample, the same four distinct profiles emerged. ANOVAs indicated that the processes of prevention varied significantly across these profiles. The prevention profiles were extended to youth in Elementary, Middle, and High Schools and from a focus on single substances to multiple substances, including alcohol, tobacco, and illicit drugs. Implications for developing prevention programs are also discussed.

Using mHealth to Deliver Behavior Change Interventions Within Prenatal Care at Community Health Centers.

PURPOSE: To test an iPad-delivered multiple behavior tailored intervention (Healthy Pregnancy: Step by Step) for pregnant women that addresses smoking cessation, stress management, and fruit and vegetable consumption. DESIGN: A randomized 2 × 5 factorial repeated measures design was employed with randomization on the individual level stratified on behavior risk. Women completed three sessions during pregnancy and two postpartum at postdelivery months 1 and 4. SETTING: Women were recruited from six locations of federally funded health centers across three states. SUBJECTS: Participants (N = 335) were English- and Spanish-speaking women at up to 18 weeks gestation. INTERVENTION: The treatment group received three interactive sessions focused on two priority health behavior risks. The sessions offered individually tailored and stage-matched change strategies based on the transtheoretical model of behavior change. The usual care group received March of Dimes brochures. MEASURES: The primary outcome was the number of behavior risks. Stage of change and continuous measures for all behaviors also were assessed. ANALYSIS: Data were analyzed across all time points using generalized estimating equations examining repeated measures effects. RESULTS: Women in the treatment group reported significantly fewer risks than those in usual care at 1 month (.85 vs. 1.20, odds ratio [OR] = .70) and 4 months postpartum (.72 vs. .91, OR = .81). CONCLUSION: Healthy Pregnancy is an evidence-based and personalized program that assists pregnant women with reducing behavior risks and sustaining healthy lifestyle behaviors.

Keepin' it R.E.A.L.!: program description and results of baseline assessment.

In this article, the authors present the results of the analysis of the baseline data from Keepin' it R.E.A.L.!, an HIV prevention project developed for mothers and their adolescents. Six hundred twelve mostly male (60.6%) and African American (98.2%) adolescents completed baseline assessments. Eleven percent of the adolescent participants reported initiating sexual intercourse. Adolescent participants expressing higher levels of self-efficacy to resist peer pressure, more favorable outcome expectancies, less communication about sex with their mothers, higher levels of self-concept related to their behavior, lower levels of self-concept related to popularity, and less stress reported fewer types of intimate sexual behaviors. Adolescent participants who reported higher self-efficacy to resist peer pressure to have sex and lower levels of stress were less likely to have initiated sexual intercourse. Selected characteristics of mothers did not contribute to understanding factors associated with intimate sexual behaviors or initiation of sexual intercourse among adolescent participants.

An assessment of the HIV/AIDS knowledge, attitudes, and behaviors of adolescents living in a large metropolitan area.

This article assesses the HIV/AIDS knowledge, attitudes, and behaviors of a predominately African-American sample of adolescents (N=1503) attending 8th grade in a major Southeastern metropolitan area. Although their knowledge about human immunodeficiency virus (HIV) transmission was high, respondents held several misconceptions about HIV and acquired immunodeficiency syndrome (AIDS), and not all students knew which type of condom effectively blocks HIV transmission. Respondents in general felt confident that they could resist pressure to smoke marijuana or drink alcohol, but were less confident of their ability to resist pressure to have sex. Sexual activity was also more prevalent than drinking and smoking marijuana among this group of adolescents. Information from this and similar assessments can facilitate responsiveness of healthcare professions to the current educational needs of adolescents.

An Internet-Based Computer-Tailored Intervention to Promote Responsible Drinking: Findings from a Pilot Test with Employed Adults.

This paper describes pilot test findings of an Internet-based, Transtheoretical Model-based, computer tailored intervention for adults who exceed national guidelines for low-risk drinking. In a pilot test, 166 adults recruited from worksites completed one session and evaluated the program. Pre and post assessments indicate intention to make behavioral changes. Importantly, 94.3% of participants indicated that they would recommend the program. Ratings were positive with the majority of participants 'agreeing' or 'strongly agreeing' with all 14 evaluation items. Feasibility was demonstrated by recruiting and engaging employed adults. This program is a cost-effective prevention program promoting responsible drinking to adults.

Randomized trial of a computer-tailored intervention for patients with depression.

PURPOSE. Examine the efficacy of a computer-tailored intervention (CTI) based on the transtheoretical model (TTM) for reducing depression, an increasingly important component of health promotion programs. DESIGN. Pretest-posttest randomized trial. Setting . Participants were recruited and treated at home after being identified in two primary care clinics in Eastern Massachusetts and Chicago, Illinois. SUBJECTS. A total of 350 adults experiencing at least mild symptoms of depression but not involved in or planning to seek treatment for depression. INTERVENTION. A print manual and three CTI reports tailored to stage of change for using effective methods to prevent or reduce depression, other TTM variables, level of depression, and behavior. . Pre-post changes and reliable and clinically significant change on the Beck Depression scale II and pre-post changes on the 20-item Medical Outcomes Study Short Form survey-based measure of physical functioning at 9 months' follow-up. ANALYSIS. t-tests and χ(2) tests. Complete-case analysis and two intention-to-treat analyses-assumption of no change and multiple imputation (MI)-are reported. Exploratory analyses examined whether the effects of the intervention on depression were moderated by five subject characteristics: baseline level of depression, baseline level of physical functioning, baseline stage of change for preventing or managing depression, age, and education. RESULTS. Complete-case and intention-to-treat analyses showed that the intervention group experienced significantly greater improvements in depression (d  =  .220-.355); results for physical functioning were weaker (d  =  .150-.309) and did not reach statistical significance in the MI analysis. The effects of the intervention on reliable and clinically significant change in depression were largest among participants who were experiencing moderate depression (d  =  .363-.519) or severe depression (d  =  .603-.718) or who were in the precontemplation or contemplation stage (d  =  .573-.856) at baseline.
