The Adolescent Lifestyle Profile: development and psychometric characteristics.
ABSTRACT Adolescents establish patterns of behavior and make lifestyle choices that affect their future health during their transition from childhood to adulthood. They struggle with behaviors, such as physical activity and nutrition, which will affect their risk of developing chronic diseases in adulthood. A comprehensive, easy to administer instrument is needed that is both research worthy and clinically useful in order to assess adolescent lifestyle behaviors and to plan interventions appropriately. The purpose of this paper is to report the development and testing of the Adolescent Lifestyle Profile (ALP), a Likert-type instrument to measure seven domains of a health-promoting lifestyle in adolescents. The ALP was modeled after the Health Promoting Lifestyle Profile II (HPLP II) and tested in a sample of early adolescents. Internal consistency reliability, including Cronbach's alpha, item to total correlations and subscale to total scale correlations and construct validity, including concurrent validity testing and factor analysis, indicated that the ALP is a reliable and valid scale that can be used to assess healthy lifestyle domains in adolescents.

ABSTRACT: To develop and test the validity of the Behavior, Environment, and Changeability Survey (BECS) for identifying the importance and changeability of nutrition, exercise, and stress management behavior and related aspects of the environment. A cross-sectional, online survey of the BECS and selected validated instruments. Ten state universities. A convenience sample of college students (n = 1,283), ages 18-24 years. Principal component analysis was used to confirm a 6-component structure of the BECS in 2 independent samples for the purpose of cross-validation. Internal consistency was measured and construct and criterion-related analyses were conducted to test the reliability and validity of the BECS subscales. Six components representing 34 BECS items were revealed from the original 69 items and explained 64% of the total variance. Six scales were retained, and internal consistency of each ranged from α = .82 to .93. BECS Nutrition Behavior and Nutrition Changeability scale scores were highest for participants in action/maintenance Stages of Change for fruit and vegetable intake. There is strong support for the use of the BECS when planning health programs to gain insight into behavior that young adults are willing to improve, specifically related to nutrition, exercise, and sleep.Journal of nutrition education and behavior 11/2012; 44(6):490-9. · 1.36 Impact Factor

ABSTRACT: Lifestyle choices and individuals' behaviors have the potential to influence health and improve the quality of life. The purpose of this study was to develop and psychometrically test an instrument for measuring healthy lifestyle in Iranian adolescents. A comprehensive literature review related to health-promoting lifestyles was used to identify potential scale items. Data were collected from 797 school students. Construct validity was analyzed using exploratory factor analysis. Confirmatory factor analysis (CFA) was used to cross-validate. Nine factors emerged that explained 59.8% of the variance in the 43 items. Cronbach's α coefficient Healthy Lifestyle Questionnaire was r=0.82. After the model was modified, the fit indices indicated that the data were an adequate-to-good fit to the proposed models. The current study provides some support to the internal and external validity of the healthy lifestyles questionnaire for Iranian adolescents.Journal of education and health promotion. 01/2012; 1:20.

ABSTRACT: Very little is known about predictors of subjective health status among African American adolescents. This study was designed to determine whether selected anthropometric, psychological, lifestyle behavioral, and structural variables predicted poor self-rated general health in a cross-sectional nonclinical sample of 310 female African American adolescents, 14-18 years old. The odds of reporting poor self-rated health were 2-3 times greater for African American teens from lower socioeconomic households when compared to teens residing in higher socioeconomic households and for those reporting infrequent participation in activities that promote spiritual well-being compared to those who participate more frequently in activities that enhance spiritual health. Findings indicate that socioeconomic level and engagement in behaviors that enhance healthy spirituality appear to be the most salient predictors of self-rated health. In addition to biodiversity considerations that influence perceptions of health status, culturally focused interventions should integrate variables shown to influence self-rated health among African American teens. These inclusions may inform a more integrated understanding of health, health outcomes, and health disparities in this vulnerable population.Research in Nursing & Health 03/2012; 35(3):219-30. · 2.18 Impact Factor
