To describe the development of the Pittsburgh Fatigability Scale (PFS) and establish its reliability and concurrent and convergent validity against performance measures.
Design
Cross‐sectional.
Setting
University of Pittsburgh, Pittsburgh, Pennsylvania.
Participants
Scale development sample: 1,013 individuals aged 60 and older from two registries; validation sample: 483 adults aged 60 and older from the Baltimore Longitudinal Study of Aging (BLSA).
Measurements
The scale development sample and BLSA participants self‐administered an initial 26‐item perceived fatigability scale. BLSA participants also completed measures of performance fatigability (perceived exertion from a standard treadmill task and performance deterioration from a fast‐paced long‐distance corridor walk), a 6‐m usual‐paced corridor walk, and five timed chair stands.
Results
Principal components analysis with varimax rotation reduced the 26‐item scale to the 10‐item PFS. The PFS showed strong internal consistency (Cronbach's alpha 0.88) and excellent test–retest reliability (intraclass correlation 0.86). In the validation sample, PFS scores, adjusted for age, sex, and race, were greater for those with high performance fatigability, slow gait speed, worse physical function, and lower fitness, with differences between high and low fatigability ranging from 3.2 to 5.1 points (P |

The 10‐item PFS physical fatigability score is a valid and reliable measure of perceived fatigability in older adults and can serve as an adjunct to performance‐based fatigability measures for identifying older adults at risk of mobility limitation in clinical and research settings.</description><identifier>ISSN: 0002-8614</identifier><identifier>EISSN: 1532-5415</identifier><identifier>DOI: 10.1111/jgs.13191</identifier><identifier>PMID: 25556993</identifier><identifier>CODEN: JAGSAF</identifier><language>eng</language><publisher>United States: Blackwell Publishing Ltd</publisher><subject>Activities of Daily Living ; Aged ; Aging ; Cross-Sectional Studies ; Disability Evaluation ; fatigability ; Fatigue ; Fatigue - diagnosis ; Female ; Geriatric Assessment - methods ; Geriatrics ; Humans ; Male ; Middle Aged ; mobility ; Mobility Limitation ; Pennsylvania ; performance measures ; Physical Exertion ; validation ; Walking - physiology</subject><ispartof>Journal of the American Geriatrics Society (JAGS), 2015-01, Vol.63 (1), p.130-135</ispartof><rights>2014, Copyright the Authors Journal compilation © 2014, The American Geriatrics Society</rights><rights>2014, Copyright the Authors Journal compilation © 2014, The American Geriatrics Society.</rights><rights>2015 American Geriatrics Society and Wiley Periodicals, Inc</rights><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c4811-5d64265ef424f029c1878642df4eebc96060803f94b0a8305ef1523610cd123a3</citedby><cites>FETCH-LOGICAL-c4811-5d64265ef424f029c1878642df4eebc96060803f94b0a8305ef1523610cd123a3</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://onlinelibrary.wiley.com/doi/pdf/10.1111%2Fjgs.13191$$EPDF$$P50$$Gwiley$$H</linktopdf><linktohtml>$$Uhttps://onlinelibrary.wiley.com/doi/full/10.1111%2Fjgs.13191$$EHTML$$P50$$Gwiley$$H</linktohtml><link.rule.ids>230,314,780,784,885,1416,27922,27923,45572,45573</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/25556993$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Glynn, Nancy W.</creatorcontrib><creatorcontrib>Santanasto, Adam J.</creatorcontrib><creatorcontrib>Simonsick, Eleanor M.</creatorcontrib><creatorcontrib>Boudreau, Robert M.</creatorcontrib><creatorcontrib>Beach, Scott R.</creatorcontrib><creatorcontrib>Schulz, Richard</creatorcontrib><creatorcontrib>Newman, Anne B.</creatorcontrib><title>The Pittsburgh Fatigability Scale for Older Adults: Development and Validation</title><title>Journal of the American Geriatrics Society (JAGS)</title><addtitle>J Am Geriatr Soc</addtitle><description>Objectives
