Validity and reliability of questionnaires measuring physical activity self-efficacy, enjoyment, social support among Hong Kong Chinese children

Abstract

BackgroundPhysical activity (PA) correlates have not been extensively studied in Hong Kong children.ObjectiveThe aim of this study is to assess the validity and reliability of translated scales to measure PA related self-efficacy, enjoyment and social support in Hong Kong Chinese children.MethodsSample 1 (n = 273, aged 8–12 years) was recruited (May–June, 2013) from two primary schools. Confirmatory factor analyses (CFA) were conducted to assess factorial validity. Criterion validity was assessed by correlating measured constructs with self-reported PA. Cronbach's alpha was computed to assess scale internal consistency. The intraclass correlation coefficient (ICC) was performed to assess scale test–retest reliability. Criterion validity was further examined in Sample 2 (n = 84, aged 8–12 years) from a third school by correlating measured constructs with objectively measured PA collected in September 2013 and February 2014.ResultsThe CFA results supported the one-factor structure of the scales. All PA correlates were significantly (p < 0.01) associated with self-reported PA in Sample 1. Self-efficacy and enjoyment were significantly (p < 0.05) correlated with objectively measured PA in Sample 2. All the scales demonstrated acceptable internal consistency. All ICC values of the scales suggested acceptable test–retest reliability.ConclusionThe results provide psychometric support for using the scales to measure PA correlates among Hong Kong Chinese children.

Effects of guided inquiry virtual and physical laboratories on conceptual understanding, inquiry performance, scientific inquiry self-efficacy, and enjoyment

“…Sample items include the following: "I can use graphs to show what I found out in my experiment," "It is hard for me to look at the results of an experiment and tell what they mean," and "I can design an experiment to test my ideas." The enjoyment questionnaire was developed by Liang et al [61], and was found to have acceptable factorial and criterion validity, internal consistency (α ¼ 0.93), and test-retest reliability. The seven items were framed in the context of "When I am doing lab activities…" "…I feel bored" or "…I dislike it."…”

Psychometric Properties of Eight-Item Physical Activity Enjoyment Scale in a Chinese Population

“…Its validity was supported by its significant correlation with the Boredom Proneness Scale score (r = −.30). The Chinese version has been identified as valid and reliable for use in children (Liang, Lau, Huang, Maddison, & Baranowski, 2014) and university students (Zhou, Keating, Zhou, Shanguan, & Liu, 2015).…”

Las estrategias cognitivo-conductuales y expectativas sobre sus beneficios median la relación entre apoyo social parental y frecuencia de actividad física de los adolescentes

“…El apoyo social, tanto materno como paterno, fue evaluado a partir de una escala compuesta por 10 ítems (Liang, Lau, Huang, Maddison, & Baranowski, 2014) que se adaptaron a partir de los incluidos en la Escala de Apoyo Social para el Ejercicio . Respecto al instrumento original, Liang et al (2014), sustituyeron el término "ejercicio físico" por el de "actividad física".…”

Respecto al instrumento original, Liang et al (2014), sustituyeron el término "ejercicio físico" por el de "actividad física". Los participantes indicaban el grado de acuerdo mostrado con una serie de afirmaciones relativas al apoyo social que creían haber recibido por parte de madres y padres para la práctica de actividad física a lo largo del último año (p.e.…”
