In this paper we examine the measurement properties of the LLDI using data from the Lifestyle Interventions and Independence for Elders Pilot LIFE-P study. Methods LIFE-P participants aged 70-89 years were at elevated risk of disability. The 424 participants were enrolled at the Cooper Institute Stanford University University of Pittsburgh and Wake Forest University. Physical activity and successful aging health education interventions were compared after 12-months of follow-up. Using factor analysis we determined whether the LLDI s factor structure was comparable with that reported previously. We further examined how each item related to measured disability using item response theory IRT . Results The factor structure for the limitation domain within the LLDI in the LIFE-P study did not corroborate previous findings. However the factor structure using the abbreviated version was supported. Social and personal role factors were identified. IRT analysis revealed that each item in the social role factor provided a similar level of information whereas the items in the personal role factor tended to provide different levels of information. Conclusions Within the context of community-based clinical intervention research in aged populations an abbreviated version of the LLDI performed better than the .
