Test–retest reliability of the Brunel Lifestyle Physical Activity Questionnaire

Abstract

Objectives\ud \ud To establish the test–retest reliability of planned physical activity (PPA) and unplanned physical activity (UPA) components of the Brunel Lifestyle Physical Activity Questionnaire (BLPAQ). To provide evidence of the BLPAQ's stability using the proportion of agreement (PoA) method over a 5-week period.\ud \ud Design\ud \ud Test–retest over a 5-week period using three diverse samples of adults.\ud \ud Methods\ud \ud The 277 participants were subdivided into three adult samples: gymnasium users (n = 80), undergraduate students (n = 111), and university staff members (n = 86). They were asked to complete the test–retest measure in their places of exercise, study, or work respectively.\ud Results\ud \ud Correlation coefficients between test–retest administrations were calculated for each participant group and intraclass correlations were calculated for each item. Pearson's product-moment correlations ranged from r = 0.95 to r = 0.96 for the PPA subscale and r = 0.93 to r = 0.98 for the UPA subscale. Intraclass correlations ranged from R = 0.52 to R = 0.99 for PPA and R = 0.87 to R = 0.99 for UPA. Fisher's z tests indicated that the test–retest correlation coefficients for the BLPAQ subscales were, on the whole, significantly stronger than those of older, comparable subscales from lifestyle physical activity questionnaires. The PoA analysis for each item revealed that the test–retest administrations were in high agreement (>95%).\ud Conclusions\ud \ud Overall, the PPA and UPA factors of the BLPAQ demonstrated high reliability and stability. The present study also illustrates the utility of PoA analysis in establishing the stability of physical activity measures

Impact of COVID-19 restrictions on mental health and physical activity among LGBQAP and heterosexual adults

“…Participants were asked to respond to the nine items in this scale (six for planned PA and three for unplanned PA) using a 5-point, continuous-closed numerical scale (e.g., 1 = Not at all, 5 = Highly). Reliability and validity of the BLPAQ scores have been demonstrated in previous studies (Vencato et al, 2017a;Vencato et al, 2017b). In the present sample, internal consistency estimates for planned PA were .91 (prior to lockdown) and .93 during lockdown).…”

Physical activity and mental well-being under COVID-19 lockdown: a cross-sectional multination study

“…Factor scores ranged from 1.00-5.00, with higher scores indicating higher engagement in PA. The BLPAQ has acceptable test-retest reliability and is a criterion-and cross-validated measure of physical activity [29,30]. Cronbach's alpha coefficients for planned PA was 0.92 (pre-lockdown) and 0.93 (during lockdown) in the present sample.…”

Relationships among behavioural regulations, physical activity, and mental health pre- and during COVID–19 UK lockdown

“…Factor scores ranged from 1 to 5, with higher scores indicating higher PA engagement. The BLPAQ is a criterion- and cross-validated measure of PA that exhibits high test–retest reliability ( Vencato, Karageorghis, Nevill, et al, 2017 ; Vencato, Karageorghis, Priest, et al, 2017 ). Participants were also asked to specify their average step count per day, but only if they used a mobile device (e.g., a smartwatch) for this purpose ( n = 190; 18–85 years; M BMI = 25.06; SD BMI = 4.90; 148 women).…”
