Three levels of complexity of out-of-home behavior were distinguished: (a) mostly automatized walking behavior (low complexity), (b) global out-of-home mobility (medium complexity), and (c) defined units of concrete out-of-home activities, particularly cognitively demanding activities (high complexity). A sample of 257 older adults aged 59 to 91 years ( M = 72.9 years, SD = 6.4 years) included 35 persons with early-stage Alzheimer\u2019s disease (AD), 76 persons with mild cognitive impairment (MCI), and 146 cognitively healthy persons (CH). Mobility data were gathered by using a GPS tracking device as well as by questionnaire. Predicting cognitive impairment status by out-of-home behavior and a range of confounders by means of multinomial logistic regression revealed that only cognitively demanding activities showed at least a marginally significant difference between MCI and CH and were highly significant between AD and CH.<\/jats:p>","DOI":"10.1177\/0733464812459373","type":"journal-article","created":{"date-parts":[[2012,9,24]],"date-time":"2012-09-24T22:22:58Z","timestamp":1348525378000},"page":"3-25","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":74,"title":["Out-of-Home Behavior and Cognitive Impairment in Older Adults"],"prefix":"10.1177","volume":"34","author":[{"given":"Markus","family":"Wettstein","sequence":"first","affiliation":[{"name":"Heidelberg University, Heidelberg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hans-Werner","family":"Wahl","sequence":"additional","affiliation":[{"name":"Heidelberg University, Heidelberg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Noam","family":"Shoval","sequence":"additional","affiliation":[{"name":"Hebrew University Jerusalem, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frank","family":"Oswald","sequence":"additional","affiliation":[{"name":"Goethe University, Frankfurt, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elke","family":"Voss","sequence":"additional","affiliation":[{"name":"Central Institute of Mental Health, Mannheim, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ulrich","family":"Seidl","sequence":"additional","affiliation":[{"name":"Klinikum Stuttgart, Department of Psychiatry, Stuttgart, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lutz","family":"Fr\u00f6lich","sequence":"additional","affiliation":[{"name":"Central Institute of Mental Health, Mannheim, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gail","family":"Auslander","sequence":"additional","affiliation":[{"name":"Hebrew University Jerusalem, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeremia","family":"Heinik","sequence":"additional","affiliation":[{"name":"Tel Aviv University, Tel Aviv, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruth","family":"Landau","sequence":"additional","affiliation":[{"name":"Hebrew University Jerusalem, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2012,9,24]]},"reference":[{"key":"bibr1-0733464812459373","first-page":"569","volume-title":"Handbook of child psychology.
