Validation of the Kidney Disease Quality of Life Short Form 36 (KDQOL-36™) US Spanish and English Versions in a Cohort of Hispanics with Chronic Kidney Disease
Evaluate the reliability and validity of the Kidney Disease Quality of Life Short Form 36 (KDQOL-36) in Hispanics with mild-to-moderate chronic kidney disease (CKD).

Cross-sectional
Chronic Renal Insufficiency Cohort Study
420 Hispanic (150 English- and 270 Spanish-speakers), and 409 non-Hispanic White individuals, matched by age (mean 57 years), sex (60% male), kidney function (mean estimated glomerular filtration rate 36ml/min/1.73m2), and diabetes (70%).
To measure construct validity, we selected instruments, comorbidities, and laboratory tests related to at least one KDQOL-36 subscale. Reliability was determined by calculating Cronbach's alpha.
Reliability of each KDQOL-36 subscale [SF-12 Physical Component Summary (PCS) and Mental Component Summary (MCS), Symptoms/Problems, Burden of Kidney Disease and Effects of Kidney Disease] was very good (Cronbach's alpha >0.8). Construct validity was supported by expected negative correlation between MCS scores and the Beck Depression Inventory in all three subgroups (r=-0.56 to -0.61, P |

Reliability of each KDQOL-36 subscale [SF-12 Physical Component Summary (PCS) and Mental Component Summary (MCS), Symptoms/Problems, Burden of Kidney Disease and Effects of Kidney Disease] was very good (Cronbach's alpha >0.8). Construct validity was supported by expected negative correlation between MCS scores and the Beck Depression Inventory in all three subgroups (r=-0.56 to -0.61, P<.0001). There was inverse correlation between the Symptoms/ Problems subscale and the Patient Symptom Form (r= -0.70 to -0.77, P<.0001). We also found significant, positive correlation between the PCS score and a physical activity survey (r=+0.29 to +0.38, P< or =.003); and between the PCS and MCS scores and the Kansas City Questionnaire (r= +0.31 to +0.64, P<.0001). Reliability and validity were similar across all racial/ethnic groups analyzed separately.
Our findings support the use of the KDQOL-36 as a measure of HRQOL in this cohort of US Hispanics with CKD.</description><identifier>ISSN: 1049-510X</identifier><identifier>PMID: 23530302</identifier><language>eng</language><publisher>United States: Ethnicity & Disease, Inc</publisher><subject>Aged ; Cohort Studies ; Cross-Sectional Studies ; Female ; Health Status Indicators ; Humans ; Language ; Male ; Middle Aged ; Original Reports: Diabetes and Other Chronic Diseases ; Quality of Life ; Renal Insufficiency, Chronic ; United States</subject><ispartof>Ethnicity & disease, 2013-01, Vol.23 (2), p.202-209</ispartof><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://www.jstor.org/stable/pdf/48667836$$EPDF$$P50$$Gjstor$$H</linktopdf><linktohtml>$$Uhttps://www.jstor.org/stable/48667836$$EHTML$$P50$$Gjstor$$H</linktohtml><link.rule.ids>230,314,780,784,803,885,58017,58250</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/23530302$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Ricardo, Ana C.</creatorcontrib><creatorcontrib>Hacker, Eileen</creatorcontrib><creatorcontrib>Lora, Claudia M.</creatorcontrib><creatorcontrib>Ackerson, Lynn</creatorcontrib><creatorcontrib>DeSalvo, Karen B.</creatorcontrib><creatorcontrib>Go, Alan</creatorcontrib><creatorcontrib>Kusek, John W.</creatorcontrib><creatorcontrib>Nessel, Lisa</creatorcontrib><creatorcontrib>Ojo, Akinlolu</creatorcontrib><creatorcontrib>Townsend, Raymond R.</creatorcontrib><creatorcontrib>Xie, Dawei</creatorcontrib><creatorcontrib>Ferrans, Carol E.</creatorcontrib><creatorcontrib>Lash, James P.</creatorcontrib><creatorcontrib>CRIC Investigators</creatorcontrib><title>Validation of the Kidney Disease Quality of Life Short Form 36 (KDQOL-36™) US Spanish and English Versions in a Cohort of Hispanics with Chronic Kidney Disease</title><title>Ethnicity & disease</title><addtitle>Ethn Dis</addtitle><description>Evaluate the reliability and validity of the Kidney Disease Quality of Life Short Form 36 (KDQOL-36) in Hispanics with mild-to-moderate chronic kidney disease (CKD).
