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: Health-promoting behaviors are important to prevent diseases and prolong life in the population. People develop these behaviors throughout life. However, better benefits for health are obtained with an early development.Revista medica de Chile 04/2014; 142(4):418-27. · 0.37 Impact Factor

ABSTRACT: Background: Health-promoting lifestyle choices of adolescents are closely related to current and subsequent health status. However, parsimonious yet reliable and valid screening tools are scarce. The original 40-item adolescent health promotion (AHP) scale was developed by our research team and has been applied to measure adolescent health-promoting behaviors worldwide. The aim of our study was to examine the psychometric properties of a newly developed short-form version of the AHP (AHP-SF) including tests of its reliability and validity. Methods: The study was conducted in nine middle and high schools in southern Taiwan. Participants were 814 adolescents randomly divided into two subgroups with equal size and homogeneity of baseline characteristics. The first subsample (calibration sample) was used to modify and shorten the factorial model while the second subsample (validation sample) was utilized to validate the result obtained from the first one. The psychometric testing of the AHP-SF included internal reliability of McDonald’s omega and Cronbach's alpha, convergent validity, discriminant validity, and construct validity with confirmatory factor analysis (CFA). Results: The results of the CFA supported a six-factor model and 21 items were retained in the AHP-SF with acceptable model fit. For the discriminant validity test, results indicated that adolescents with lower AHP-SF scores were more likely to be overweight or obese, skip breakfast, and spend more time watching TV and playing computer games. The AHP-SF also showed excellent internal consistency with a McDonald’s omega of 0.904 (Cronbach’s alpha 0.905) in the calibration group. Conclusion: The current findings suggest that the AHP-SF is a valid and reliable instrument for the evaluation of adolescent health-promoting behaviors. Primary health care providers and clinicians can use the AHP-SF to assess these behaviors and evaluate the outcome of health promotion programs in the adolescent population.BMC Public Health 10/2014; 14:1106.

ABSTRACT: Reliable and valid instruments are essential for understanding health-promoting behaviors in adolescents. This study analyzed the psychometric properties of the Portuguese version of the Adolescent Lifestyle Profile (ALP). A linguistic and cultural translation of the ALP was conducted with 236 adolescents from two different settings: a community (n=141) and a clinical setting (n=95). Internal consistency reliability and confirmatory factor analysis were performed. Results showed an adequate fit to data, yielding a 36-item, seven-factor structure (CMIN/DF=1.667, CFI=0.807, GFI=0.822, RMR=0.051, RMSEA=0.053, PNFI=0.575, PCFI=0.731). The ALP presented a high internal consistency (α=0.866), with the subscales presenting moderate reliability values (from 0.492 to 0.747). The highest values were in Interpersonal Relations (3.059±0.523) and Positive Life Perspective (2.985±0.588). Some gender differences were found. Findings showed that adolescents from the clinic reported an overall healthier lifestyle than those from the community setting (2.598±0.379 vs. 2.504±0.346; t=1.976, p=0.049). The ALP Portuguese version is a psychometrically reliable, valid, and useful measurement instrument for assessing health-promoting lifestyles in adolescence. The ALP is cross-culturally validated and can decisively contribute to a better understanding of adolescent health promotion needs. Additional research is needed to evaluate the instrument's predictive validity, as well as its clinical relevance for practice and research. Copyright © 2015 Sociedade Brasileira de Pediatria.
