Protocol - Life Space

Personnel and Training Required

The interviewer must be trained to conduct personal interviews with individuals from the general population. The interviewer must be trained and found to be competent (i.e., tested by an expert) at the completion of personal interviews. The interviewer should be trained to prompt respondents further if a "dont know" response is provided.

Equipment Needs

The PhenX Working Group acknowledges that these questions can be administered in a computerized or noncomputerized format (i.e., paper-and-pencil instrument). Computer software is necessary to develop computer-assisted instruments. The interviewer will require a laptop computer/handheld computer to administer a computer-assisted questionnaire.

Selection Rationale

This Life Space protocol has been used in studies showing that life space - or mobility area - that is covered is strongly and inversely associated with mortality.

Definition

Questionnaire identifying how much an individual gets out and about and the spatial extent of the person's typical life space.

Purpose

A key characteristic of mobility is the range of movement within an individual's environment. As people age and are in community-dwelling environments, their mobility often decreases.

Keywords

The Life Space Questionnaire, geriatrics, aging, movement, travel restriction, mobility, community-dwelling older adults, gerontology, aging
