ABSTRACT To assess the test-retest reliability and validity of a modified self-administered version of the Active Australia physical activity survey.
One hundred and fifty-nine mid-age women (54-59 years) completed a mailed physical activity questionnaire before recording daily pedometer step counts for seven consecutive days. A random subsample (n=44) also wore an accelerometer during this period. Participants then completed the physical activity questionnaire again. Spearman's rho and per cent agreement were used to assess test-retest reliability. Self-reported physical activity data (time 2) were compared with pedometer and accelerometer data using box plots and Spearman's correlations to assess validity.
Median time between surveys was 13 days. Median frequency and duration of moderate and vigorous physical activity were the same at both surveys, but median walking frequency was slightly higher at time 2 than time 1. Reliability coefficients for frequency/time in each domain of physical activity ranged from 0.56-0.64 and per cent agreement scores ranged from 40% to 65% for the physical activity categories; agreement was 76% for 'meeting guidelines'. Correlations (p) between self-reported physical activity and 1) weekly pedometer steps and 2) accelerometer data for duration of at least moderate intensity physical activity were 0.43 and 0.52 respectively.
The measurement properties of this modified self-administered physical activity survey are similar to those reported for the original computer assisted telephone interview survey.
This modified version of the Active Australia survey is suitable for use in self-administered format.

    ABSTRACT: Abstract We examined physical activity stage of change, physical activity behaviour, and role overload in different stages of motherhood in a predominantly Australian sample. Neither physical activity behaviour, stages of physical activity change, nor role overload significantly differed across motherhood groups. Role overload was significantly higher for mothers in the contemplation, planning, and action stages of physical activity than the maintenance stage of change. Role overload was weakly, although significantly, negatively correlated with leisure time physical activity. We conclude strategies focused upon reducing role overload or perceived role overload, have only limited potential to meaningfully increase leisure-time physical activity in mothers.

    • "The questionnaire distinguishes between walking, leisure-time physical activity and physical activity relating to household chores. Reliability coefficients for frequency/time in each domain of physical activity range from 0.56 to 0.64 and the percent agreement scores range from 40 to 65% for the physical activity categories [43]. Total past-week minutes spent in moderate-to-vigorous physical activity (MVPA) are calculated and converted to average minutes/day. "

    ABSTRACT: Pediatric primary care is an important setting in which to address obesity prevention, yet relatively few interventions have been evaluated and even fewer have been shown to be effective. The development and evaluation of cost-effective approaches to obesity prevention that leverage opportunities of direct access to families in the pediatric primary care setting, overcome barriers to implementation in busy practice settings, and facilitate sustained involvement of parents is an important public health priority. The goal of the Healthy Homes/Healthy Kids (HHHK 5-10) randomized controlled trial is to evaluate the efficacy of a relatively low-cost primary care-based obesity prevention intervention aimed at 5 to 10 year old children who are at risk for obesity. Four hundred twenty one parent/child dyads were recruited and randomized to either the obesity prevention arm or a contact control condition that focuses on safety and injury prevention. The HHHK 5-10 obesity prevention intervention combines brief counseling with a pediatric primary care provider during routine well-child visits and follow-up telephone coaching that supports parents in making home environmental changes to support healthful eating, activity patterns, and body weight. The contact control condition combines the same provider counseling with telephone coaching focused on safety and injury prevention messages. This manuscript describes the study design and baseline characteristics of participants enrolled in the HHHK 5-10 trial.

The AAS survey has good test-retest reliability (Brown et al., 2004), good validity with objective accelerometer measured physical activity (Brown et al., 2008), and is sensitive to change in intervention trials (Reeves et al., 2010). Respondents were also asked to report minutes per weekday and weekend day they spent sitting while traveling, at work, watching TV, etc. (Marshall et al., 2010). "

    ABSTRACT: During the postpartum period, ethnic minority women have higher rates of inactivity/under-activity than white women. The Nā Mikimiki ("the active ones") Project is designed to increase moderate-to-vigorous physical activity over 18 months among multiethnic women with infants 2-12 months old. The study was designed to test, via a randomized controlled trial, the effectiveness of a tailored telephone counseling of moderate-to-vigorous physical activity intervention compared to a print/website materials-only condition. Healthy, underactive women (mean age = 32 ± 5.6 years) with a baby (mean age = 5.7 ± 2.8 months) were enrolled from 2008-2009 (N = 278). Of the total sample, 84% were ethnic minority women, predominantly Asian-American and Native Hawaiian. Mean self-reported baseline level of moderate-to-vigorous physical activity was 40 minutes/week with no significant differences by study condition, ethnicity, infant's age, maternal body mass index, or maternal employment. Women had high scores on perceived benefits, self-efficacy, and environmental support for exercise but low scores on social support for exercise. This multiethnic sample's demographic and psychosocial characteristics and their perceived barriers to exercise were comparable to previous physical activity studies conducted largely with white postpartum women. The Nā Mikimiki Project's innovative tailored technology-based intervention and unique population are significant contributions to the literature on moderate-to-vigorous physical activity in postpartum women.
