Comparability and Reliability of Paper- and Computer-Based Measures of Psychosocial Constructs for Adolescent Physical Activity and Sedentary Behaviors

Abstract

This study assessed the comparability and reliability of paper-based and computer-based administration of psychosocial construct measures related to adolescents engaging in physical activity and sedentary behaviors. Adolescents (n = 76; 55% girls, 49% Hispanic, 18% non-Hispanic-white; M age = 13 years) completed measures of behavior change strategies, self-efficacy, decisional balance, family and peer influences, enjoyment, activity choices, and environmental influences. Overall, the adolescents provided equivalent responses on paper and computer formats. Reliability estimates were generally good for the multiple-item constructs, but single-item measures tended to demonstrate low reliability. Average scale internal consistency was significantly higher for measures administered with the computer format compared to the paper format, but test-rest reliability estimates were not significantly different between formats.

Validacao de escalas psicossociais para mudanca do consumo de frutas, legumes e verduras

“…Os construtos investigados são baseados em teorias de mudança de comportamento 10,11 que foram testadas empiricamente em estudos de validação, transversais e de intervenção na área da nutrição e em áreas correlatas 12,13,14,15,16,17,18,19 . Como ponto positivo pode-se destacar a operacionalização de todas as etapas de equivalência proposta por Reichenheim & Moraes 21 nesta temática da área de nutrição.…”

“…Assim, desenvolveram, validaram e utilizaram em estudos com diferentes delineamentos epidemiológicos os construtos dessas teorias para diversos comportamentos de saúde 12,13,14,15,16,17,18,19 . No Brasil, não foram localizados estudos de validação de escalas psicossociais para a mudança de comportamento do consumo de frutas, legumes e verduras.…”

Multifactorial research on built environment, active lifestyle and physical fitness in Czech adolescents: Design and methods of the study

“…Dotazník je složen z několika částí, které zpravidla vycházejí z již publikovaných článků či projektů. Použité otázky zaměřené na PA adolescentů byly sestaveny na základě dřívějších studií (Rosenberg et al, 2009;Prochaska, Sallis, & Long, 2001;Norman, Sallis, & Gaskins, 2005). Dotazníkové šetření probíha-lo zadáváním v on-line prostředí systému indares.com (INDARES, 2016).…”

Web-Based Physical Activity Intervention for Latina Adolescents: Feasibility, Acceptability, and Potential Efficacy of the Ni�as Saludables Study (Preprint)

“…This measure has been shown to be reliable in an ethnically diverse sample of children as young as 11. [20] The Stages of Change for Physical Activity, Processes of Change, and Selfefficacy for Physical Activity were administered monthly on the website to generate stagematched manuals and expert-system reports. These three measures have been used extensively in physical activity research.…”
