Description

A pilot test of 104 pretest—posttest observations showed that occupational therapists perceived the SAFER-HOME as clinically useful, practical to administer, and sensitive in detecting changes. This article describes the development, factor analysis, reliability, and validity of the Safety Assessment of Function and the Environment for Rehabilitation-Health Outcome Measurement and Evaluation (SAFER-HOME). A pilot test of 104 pretest—posttest observations showed that occupational therapists perceived the SAFER-HOME as clinically useful, practical to administer, and sensitive in detecting changes. Using a factor analysis of 1,173 observations, a 10-factor structure SAFER-HOME v.2 was developed. The 93-item SAFER-HOME had an internal consistency coefficient alpha value of 0.86. The low correlations between the SAFER-HOME v.2 and the Functional Autonomy Measuring System (r = −0.206; p = .018) supported the presumption that home safety was related but not limited to functioning. There is some evidence supporting the SAFER-HOME v.2 as a valid and reliable instrument. The SAFER-HOME v.2 represents a carefully constructed, theoretically driven, and clinically sound outcome measure for use by occupational therapists to assess home safety.
