Development and Validation of the iDI: A Short Self-Rating Disability Instrument for Low Back Pain Disorders

Abstract

Study Design:Cross-sectional and longitudinal validation study.Objective:Development and validation of a short, reliable, and valid questionnaire for the assessment of low back pain–related disability.Methods:The iDI was created in a stepwise procedure: (1) its development was based on the literature and theoretical consideration; (2) outcome data were collected and evaluated in a pilot study; (3) final validations were performed based on an international multicenter spine surgery outcome study including 514 patients; (4) the iDI was programmed for a tablet computer (iPad) and tested for its clinical practicability.Results:The final version of the iDI comprises of 8 simple questions related to different aspects of disability with a 5-point Likert-type answer scale. The iDI compared very well to the Oswestry Disability Index in terms of reliability and validity. The iDI was demonstrated to be suitable for data assessment on a tablet computer (iPad).Conclusions:The iDI is a short, valid, and practicable tool that facilitates routine quality assessment in terms of low back pain–related disability.

Comprehensiveness and validity of a multidimensional assessment in patients with chronic low back pain: a prospective cohort study

“…On the item level, the ODI includes statements of disability / limitation due to pain, pain changes, support needed from other persons or devices (stick or crutches), and quality of movement. The lumping together of diverse concepts blurs the specific function content [ 57 , 58 ]. This finding is endorsed by a systematic review of 36 back-specific questionnaires whose constructs included psychosocial and physical functions as well as pain and sleep [ 54 ].…”

Evaluation of short-term effects of three passive aquatic interventions on chronic non-specific low back pain: Study protocol for a randomized cross-over clinical trial

“…This instrument comprises eight questions with reported high reliability. It was successfully tested on construct- and divergent-validity and compares very well to the Oswestry Disability Index regarding item quality, reliability, and validity measures in individuals with spinal disorders [ 60 , 77 ]. Limitations in Activity of Daily Living Questionnaire (LADL-Q) …”

Content Validation Instrument Rating Factors Contributing to Low Back Pain in Sports

“…Continual weight can cause the worse anatomic and functional damage in the back although those are not too strong. The wrong movement technique which is not fulfil the standard, and the history of sport injury also affects the back pain ((National Institute Of Neurological Disorders and Stroke., n.d.); (Pivotto et al, 2018); (Mirtz & Greene, 2015); (Feldman et al, 2001); (Picavet & Schuit, 2003); (Lionel, 2015); (Wáng et al, 2016); (Foster et al, 2018); ((MoM), 2015); (Elfering et al, 2017); & Loss, 2013); (Candotti et al, 2017); (Noll et al, 2015); (Pivotto et al, 2018); (Rinonapoli et al, 2017); (Ehrlich, 2003); (Green et al, 2016); (Foster et al, 2018); (Arya, 2014); (Anar, 2016)). The symptoms appeared are the memory disorders, the lacks of sensitiveness, bad concentration (grouped as cognitive dysfunction), and sleep disorder (Ehrlich, 2003) The early observation result is divided into two, they are: (1) analysis result from experts' research, (2) direct observation result on the patient of low back pain.…”

“…The first analysis result of the previous research conducted by the experts on the patients of low back pain such as like conducted by (Pivotto et al, 2018) develop an instrument as the evaluation of back pain and body posture for adult related to the risk factor of back pain. A research conducted by (Elfering et al, 2017) develop and validate the short, competent, and valid questionnaire for the assessment of the disability related to the low back pain based on electronic feature which can be accessed in tablet computer.A research by (Jacob et al, 2001), decide the reliability and internal consistency of the measurement tools related to the low back pain. A research by (Jacob et al, 2001) gives a comprehensive description about physical function test in the patient of low back pain.…”
