Reliability and criterion validity of the Self‐Administered Physical Activity Checklist in Greek children

Abstract

The purpose of this study was to assess the testÁretest reliability and criterion validity the Self-Administered Physical Activity Checklist (SAPAC) translated into the Greek language. To evaluate reliability, 72 students (35 girls and 37 boys) of the fifth and sixth grade completed SAPAC on two separate occasions, two weeks apart. Internal consistency was determined with Cronbach alpha coefficient and testÁretest reliability with the intraclass correlation coefficient (ICC). To evaluate criterion validity, the RT3 Research Tracker accelerometer was used as standard measure, in 90 randomly selected Greek children (51 girls and 39 boys), aged between 10 and 13. Each subject participated for two consecutive days. On day one, an accelerometer was fitted when school started. On day two, the accelerometers were returned and each subject completed the questionnaire. The internal consistency and the testÁretest reliability of SAPAC on total metabolic equivalent (MET) score, MET score of low physical activities (LPA) and MET score of moderate to vigorous physical activities (MVPA) were very satisfactory (all Cronbach's alpha 0.87, and all ICC 0.85, P B 0.001). The Kendall's tau-b test revealed that the degree of agreement between SAPAC and RT3 accelerometer on total MET score and MET score of MVPA were 0.31 and 0.37, respectively (P B 0.01). It was concluded that the Greek translated version of SAPAC is a reliable questionnaire that provides valid estimates of total, as well as moderate to vigorous activities MET scores.

Higher prevalence of obesity in Greek children living in rural areas despite increased levels of physical activity

“…Children were asked to read the completed questionnaire twice and the researcher provided assistance as needed. We have previously reported this questionnaire to have moderate‐to‐good reliability ( r > 0.85, P < 0.001) and validity ( r = 0.31 to 0.37, P < 0.001) …”

Propriedades psicométricas de questionários de atividade física na adolescência: revisão sistemática

“…A Tabela 1 apresenta a descrição dos 26 estudos. A confiabilidade teste-reteste foi investigada em 20 9,[14][15][16][17][18][19][20][21][22][28][29][30][31][32][33][34][35][36][37] deles, a validade de critério em 25 9,14-19,21-24,28-41 e a consistência interna em 5 16,21,37,38,40 . Em nenhum dos estudos, foi investigada a responsividade dos questionários.…”

“…Em nenhum dos estudos, foi investigada a responsividade dos questionários. A maioria dos estudos foi realizada na Europa 9,16,20,23,24,31,[35][36][37]39,41 e apenas cinco 15,21,28,30,33 deles no Brasil. Nos artigos incluídos, foram analisados 36 questionários estruturados, sendo seis de nacionalidade brasileira 15,21,28,30,33 .…”

“…Embora essas revisões apresentem um detalhamento dos questionários de avaliação do nível de AF em adolescentes disponíveis na literatura, além do relato de suas propriedades psicométricas, elas abrangem estudos publicados até 2009, o que levanta a importância de uma revisão que possa envolver estudos mais recentes [14][15][16][17][18][19][20][21][22][23][24] . Nesse contexto, o objetivo deste trabalho foi recuperar e sumarizar os estudos que avaliaram as propriedades psicométricas (confiabilidade, validade e responsividade) dos questionários utilizados para mensurar a AF em adolescentes.…”

Validity, Reliability, and Invariance of the Greek Version the Physical Activity Perceived Barriers Scale

“…All physical activities in the SAPAC were calculated in terms of: (1) physical activity METs score (MVPA METs) (min of activity X MET value); (2) weighted activity MET score (weighted MVPA METs) (min of activity X MET value X intensity rating) and (3) minutes of moderate to vigorous physical activity (min of MVPA). A recent study in Greece has demonstrated acceptable validity, reliability, and internal consistency of the SAPAC in young children [18].…”
