Capabilities and limitations of 251 severely visually impaired persons (senior high school age or older) were assessed on a range of visual environmental adaptation problems to learn how they are organized and influenced. Factor analyses indicated that problems can be grouped on the basis of eight functional domains, among which an independent living skills factor accounted for most response variance. Major influences on outcomes in these domains were acuity, age, sex, education, and perceived impact of impairment on quality of life. Results suggested the usefulness of rehabilitation programs geared to activity domains rather than to vision parameters. (CL)
