Investigating Differential Item Functioning by Chronic Diseases in the SF-36 Health Survey

Abstract

Considering the number of items and disease subgroups compared, the presence of DIF was minimal among items of the PF and MH domains of the SF-36. DIF had little effect on comparisons of sociodemographic or disease groups.

Construct validity of the late life function and disability instrument for adults with chronic conditions

“…Reliable and valid assessments of function and disability are therefore needed to evaluate clinical interventions and inform policy in this area. The Medical Outcomes Study (MOS) Short Form 36-item Health Survey (SF36) [2] is commonly used with population [3]. Despite the popularity of this scale, some authors have found that the narrow content areas inadequately assess function and disability, in particular the physical function portion of the SF36 [4].…”

Measurement invariance across chronic conditions: a systematic review and an empirical investigation of the Health Education Impact Questionnaire (heiQ™)

“…A variety of constructs were examined by the reviewed studies: physical functioning [24-32], depression [33-36], illness-related distress [37], somatization [33], mental health [31], pain [38], manual ability [39], daily activities [40-42], mobility and self-care [43], quality of life [44], health status [45], breathless severity [46], kinesiophobia [47], dementia [48], patients opinion about their doctor [49], caregiver reactions [50], stigmatization [51], physicians empathy [52] and satisfaction [53]. …”

Religiosity in black and white older Americans

“…Although MIMIC models have been developed a few decades ago, [36] they have only recently been applied in medical research. [38,49–51] This study used a single group MIMIC model to study DIF, and used an iterative procedure. This strategy has the advantage of assessing the effect of DIF on the group differences, and avoids the shortcoming of doing too many statistical tests simultaneously.…”
