Abstract

BACKGROUND:

Even when objective physical activity (PA) measures are preferred, many intervention studies with Latina women rely on self-reports because they are more feasible and the type and domain of PA is of interest.

PURPOSE:

This study examined the sensitivity and specificity of the IPAQ for detecting intervention-related changes in physical activity compared with accelerometer measurement among Latinas.

METHODS:

In March 2007, a community sample of 94 women (mean age = 36.31 ± 9.1 yr; mean body mass index = 31.37 ± 7.13) participated in a 12-week pedometer-based intervention to increase moderate intensity physical activity (MPA). Participants completed the Spanish-language International Physical Activity Questionnaire (Sp-IPAQ; telephone, long form) and wore an Actigraph accelerometer for 7 days at baseline and postintervention.

RESULTS:

Both the IPAQ and the ActiGraph accelerometer detected intervention-related increases in MPA; however, these changes were largely uncorrelated. The IPAQ did not have acceptable level of sensitivity and specificity before and after the intervention when compared with objective assessments.

CONCLUSIONS:

Data suggest that it is important to improve the sensitivity and specificity of the IPAQ with Spanish-speaking participants and further research is needed to accurately measure intervention effectiveness using self-reports of PA in Latinas.
