  • Item response theory based measure of global disability in multiple sclerosis derived from the performance scales and related Items
    BMC Neurology, 2014
    Co-Authors: Eric Chamot, Ilya Kister, Gary Cutter
    Abstract:

    The eight Performance Scales and three assimilated scales (PS) used in North American Research Committee on Multiple Sclerosis (NARCOMS) registry surveys cover a broad range of neurologic domains commonly affected by multiple sclerosis (mobility, hand function, vision, fatigue, cognition, bladder/bowel, sensory, spasticity, pain, depression, and tremor/coordination). Each scale consists of a single 6-to-7-point Likert Item with response categories ranging from “normal” to “total disability”. Relatively little is known about the performances of the summary index of disability derived from these scales (the Performance Scales Sum or PSS). In this study, we demonstrate the value of a combination of classical and modern methods recently proposed by the Patient-Reported Outcome Measurement Information System (PROMIS) network to evaluate the psychometric properties of the PSS and derive an improved measure of global disability from the PS. The study sample included 7,851adults with MS who completed a NARCOMS intake questionnaire between 2003 and 2011. Factor analysis, bifactor modeling, and Item response theory (IRT) analysis were used to evaluate the dimension(s) of disability underlying the PS; calibrate the 11 scales; and generate three alternative summary scores of global disability corresponding to different model assumptions and practical priorities. The construct validity of the three scores was compared by examining the magnitude of their associations with participant’s background characteristics, including unemployment. We derived structurally valid measures of global disability from the PS through the proposed methodology that were superior to the PSS. The measure most applicable to clinical practice gives similar weight to physical and mental disability. Overall reliability of the new measure is acceptable for individual comparisons (0.87). Higher scores of global disability were significantly associated with older age at assessment, longer disease duration, male gender, Native-American ethnicity, not receiving disease modifying therapy, unemployment, and higher scores on the Patient Determined Disease Steps (PDDS). Promising, interpretable and easily-obtainable IRT scores of global disability were generated from the PS by using a sequence of traditional and modern psychometric methods based on PROMIS recommendations. Our analyses shed new light on the construct of global disability in MS.

  • impact of the japanese 5s management method on patients and caretakers satisfaction a quasi experimental study in senegal
    Global Health Action, 2016
    Co-Authors: Shogo Kanamori, Marcia C Castro, Seydou Sow, Rui Matsuno, Alioune Cissokho, Masamine Jimba
    Abstract:

    Background : The 5S method is a lean management tool for workplace organization, with 5S being an abbreviation for five Japanese words that translate to English as Sort, Set in Order, Shine, Standardize, and Sustain. In Senegal, the 5S intervention program was implemented in 10 health centers in two regions between 2011 and 2014. Objective : To identify the impact of the 5S intervention program on the satisfaction of clients (patients and caretakers) who visited the health centers. Design : A standardized 5S intervention protocol was implemented in the health centers using a quasi-experimental separate pre-post samples design (four intervention and three control health facilities). A questionnaire with 10 five-point Likert Items was used to measure client satisfaction. Linear regression analysis was conducted to identify the intervention’s effect on the client satisfaction scores, represented by an equally weighted average of the 10 Likert Items (Cronbach’s alpha=0.83). Additional regression analyses were conducted to identify the intervention’s effect on the scores of each Likert Item. Results : Backward stepwise linear regression ( n= 1,928) indicated a statistically significant effect of the 5S intervention, represented by an increase of 0.19 points in the client satisfaction scores in the intervention group, 6 to 8 months after the intervention ( p= 0.014). Additional regression analyses showed significant score increases of 0.44 ( p= 0.002), 0.14 ( p= 0.002), 0.06 ( p= 0.019), and 0.17 ( p= 0.044) points on four Items, which, respectively were healthcare staff members’ communication, explanations about illnesses or cases, and consultation duration, and clients’ overall satisfaction. Conclusions : The 5S has the potential to improve client satisfaction at resource-poor health facilities and could therefore be recommended as a strategic option for improving the quality of healthcare service in low- and middle-income countries. To explore more effective intervention modalities, further studies need to address the mechanisms by which 5S leads to attitude changes in healthcare staff.

  • assessing research activity and capacity of community based organizations refinement of the creat instrument using the delphi method
    Journal of Urban Health-bulletin of The New York Academy of Medicine, 2019
    Co-Authors: Debbie Humphries, Nicole Collins, Jill Bazelon, Jim Pettinelli, David A Fiellin
    Abstract:

    : Community-based organizations (CBOs) are essential partners in community-engaged research, yet little is known about their research capacity. Community experts and organizations bring unique knowledge of the community to research partnerships, but standard validated measures of CBO research capacity do not yet exist. We report here on the refinement through a structured Delphi panel of a previously developed and piloted framework of CBO research capacity and an accompanying instrument, the Community REsearch Activity Assessment Tool (CREAT). A Delphi panel composed of twenty-three experts recruited from community (52%) and academic researchers (48%) from around the USA participated in five rounds of review to establish consensus regarding framework domains, operational definitions, and tool Items. Panelists rated the importance of Items on a 5-point Likert scale and assessed for the inclusion and language of Items. Initial rounds of review began with reviewing the framework and definitions, with subsequent rounds including review of the full instrument. Concluding rounds brought back Items that had not yet reached consensus for additional review. Median response values (MRV) and intra-quartile ranges (IQR) were calculated for each Likert Item. Items with an MRV > 3.5 were deemed as having reached consensus and were retained. Language changes were made for Items with MRV > 2.0 and  1.5. Items with MRV  75%). Consensus was achieved for the inclusion of all domains, subdomains and operational definitions except "evidence-based practices." Extensive changes to the CREAT instrument were made for clarification, to provide additional detail and to ensure applicability for CBOs. The CREAT framework and tool was refined through input from community and academic researchers. Availability of a validated tool to assess research capacity of CBOs will support targeted research capacity building for community organizations and partners, thus strengthening collaborations.
