Actual (reported)Construct Validity
Construct validity assesses the theoretical relationship of a measure (and resulting variables) with other variables. The multitrait-multimethod matrix (MTMM) is a procedure first developed by Campbell and Fiske to asses construct validity by creating a fully crossed method-by-measure matrix of associations among multiple constructs and multiple measurement methods. The resulting matrix of correlation coefficients gives a pattern of associations that informs the validity evidence of the measure and construct. We will use the following measures in the multitrait multimethod matrix: Neighborhood Physical Activity Questionnaire, the American Timeuse Survey, and PALMS based physical activity in location estimates.

Usability
Direct observation of research staff with no experience using the PALMS system.

Added Value
We will be assessing GPS tracks in participants in the Fe en Accion cohort to determine the effectiveness of the place-based intervention.
