The Martin and Park Environmental Demands (MPED) Questionnaire: Psychometric properties of a brief instrument to measure self-reported environmental demands


Martin, Mike; Park, Denise C (2003). The Martin and Park Environmental Demands (MPED) Questionnaire: Psychometric properties of a brief instrument to measure self-reported environmental demands. Aging Clinical and Experimental Research, 15(1):77-82.

Abstract

Background and aims: The present study examines the usefulness of a newly developed instrument, the Martin and Park Environmental Demands (MPED) Questionnaire, to measure the level of self-reported environmental demands of day-to-day events faced by adults aged 35 to 84 years, particularly as these demands influence forgetfulness in taking medications. Methods: The MPED has two scales including Busyness, which addresses the density or pace of daily events to which an individual attends; and Routine, addressing the predictability or routinization of events independent of density. The MPED was administered to a sample of 121 rheumatoid arthritis patients, along with a baseline assessment battery measuring age, education, employment status, household size and other factors that might influence self-perception of Busyness and Routine. Results: The scale showed good internal consistency and external validity. Higher levels of environmental demand were negatively correlated with age and positively correlated with employment, household size and medication-taking errors. There was a significant independent association between Busyness and adherence errors even after controlling for the effects of these sociodemographic variables. Conclusions: The MPED is recommended when trying to assess the general daily level of environmental demands
