Validation of a New Brief Physical Activity Survey among Men and Women Aged 60–69 Years

Abstract

The Stanford Brief Activity Survey (SBAS), a new two-item physical activity survey, and the Stanford Seven-Day Physical Activity Recall (PAR) questionnaire were administered to men and women, aged 60-69 years, in the Atherosclerotic Disease VAscular functioN and genetiC Epidemiology (ADVANCE) Study. Frequency distributions of SBAS activity levels, as well as a receiver operating curve, were calculated to determine if the SBAS can detect recommended physical activity levels of 150 or more minutes/week at moderate or greater intensity, with PAR minutes/week. Data were collected between December 2001 and January 2004 from 1,010 participants (38% women) and recorded. Subjects were 65.8 (standard deviation: 2.8) years of age, 77% were married, 55% were retired, 23% were college graduates, and 68% were Caucasian. SBAS scores related significantly in an expected manner to PAR minutes/week (p < 0.01), energy expenditure (kcal/kg per day) (p < 0.01), and selected cardiovascular disease risk biomarkers (p < 0.01). The SBAS of physical activity at moderate intensity had a sensitivity of 0.73 and a specificity of 0.61. The SBAS is a quick assessment of the usual amount and intensity of physical activity that a person performs throughout the day. The SBAS needs further validation in other populations but demonstrated the potential of being a reasonably valid and inexpensive tool for quickly assessing habitual physical activity in large-scale epidemiology studies and clinical practice.

Validity of Two Brief Physical Activity Questionnaires with Accelerometers among African American Women

“…These values are substantially lower than those reported in the original validation of the SBAS among a sample of older adults aged 60-69 years (Taylor-Piliae et al, 2006), as well as in another validation study examining the validity of a Spanish translated version of the SBAS . The positive predictive values for the SBAS were also lower than those in previous validations studies, whereas, the negative predictive values were slightly higher (Taylor-Piliae et al, 2006;VegaLopez et al, 2014).…”

The positive predictive values for the SBAS were also lower than those in previous validations studies, whereas, the negative predictive values were slightly higher (Taylor-Piliae et al, 2006;VegaLopez et al, 2014). The low sensitivity and low positive predictive values suggest that the SBAS has the potential to misclassify AA women who actually meet the 2008 PA Guidelines of 150 min/week of PA. On the other hand, the moderate-to-high specificity and negative predictive values of the SBAS indicate that the questionnaire is reasonably accurate for classifying AA women who do not meet the national PA Guidelines.In reference the EVS, sensitivity values were low (27% at T1, 33% at T2), while specificity values were fairly acceptable (89% at T1 and 74% at T2).…”

“…Cut-points developed from controlled laboratory experiments were used to estimate minutes of activity performed at various intensity levels: sedentary (0-99 counts/min) (Matthews et al, 2008), light (100-759 counts/min), moderate-lifestyle (760-1951 counts/min) (Matthew, 2005), moderate (1952-5725 counts/min), and vigorous (>5725 counts/min) (Freedson et al, 1998). -Piliae et al, 2006) is a two-item, self-administered PA questionnaire that can usually be completed in <5 min. The SBAS assesses both occupational (employment activity such as waitressing) and leisure-time PA (such as walking, tennis, or jogging) and classifies respondents' overall PA intensity on a five-point scale as follows: inactive (1), light (2), moderate (3), hard (4), and very hard (5).…”

The SBAS was originally validated among predominately White, English speaking older adults (aged 60-69) (Taylor-Piliae et al, 2006) and has since been validated in other populations, including middle-aged men and women with early onset coronary artery disease (TaylorPiliae et al, 2007) and post-partum Latinas (Joseph et al, 2014). However, no studies have evaluated the validity of the SBAS among AA women.…”

Gender Differences in Self-Report Physical Activity and Park and Recreation Facility Use Among Latinos in Wake County, North Carolina

“…The self-report Stanford Brief Physical Activity Survey (SBAS) [21] was used to measure work/household PA and LTPA. Since we wanted to distinguish between the two types of PA, both types of PA were analyzed separately.…”
