Social deprivation among socio-economic contrasted french areas: Using item response theory analysis to assess differential item functioning of the EPICES questionnaire in stroke patients.

ABSTRACT:

Background

Multiple approaches have been proposed to measure low socio-economic status. In France the concept of precariousness, akin to social deprivation, was developed and is widely used. EPICES is a short questionnaire that was developed to measure this concept. This study aimed to evaluate Differential Item Functioning (DIF) in the EPICES questionnaire between contrasted areas: mainland France, French West Indies (FWI) and French Guiana (FG).

Methods

The population was taken from the INDIA study, which aimed to evaluate the impact of social inequalities on stroke characteristics and prognosis. Eligible people were patients referred to neurology or emergency departments for a suspicion of stroke. We assessed the DIF using hybrid ordinal logistic regression method, derived from item response theory.

Results

We analysed 1 553 stroke patients, including 768 from FWI (49.5%), 289 from FG (18.6%) and 496 from mainland (31.9%). We identified five items with a moderate to large DIF in area comparisons: "meeting with a social worker", "complementary health insurance", "home-owning", "financial difficulties" and "sport activities". Correlation between EPICES score and the latent variable was strong (r = 0.84).

Conclusion

This is the first attempt to assess the DIF of the EPICES score between different French populations. We found several items with DIF, which can be explained by individual interpretation or local context. However, the DIFs did not lead to a large difference between the latent variable and the EPICES score, which indicates that it can be used to assess precariousness and social deprivation between contrasted areas.

Project description:BACKGROUND:Work addiction is a significant public health problem with a growing prevalence. The Work Addiction Risk Test (WART) is the gold standard questionnaire to detect workaholism. OBJECTIVE:The main objective of this study was to validate the French version of the WART. METHODS:Questionnaires were proposed to voluntary French workers using the WittyFit software. There were no exclusion criteria. The questionnaire was administered anonymously for initial validity testing and readministered one week later for test-retest reliability. We also assessed the workers' sociodemographic characteristics, as well as other measurements for external validity, such as stress, well-being, and coaddictions to tobacco, alcohol, and cannabis. Several psychometric properties of the French-WART were explored: acceptability, reliability (internal consistency [Cronbach alpha coefficient] and reproducibility [Lin concordance coefficient]), construct validity (correlation coefficients and principal component analysis), and external validity (correlation coefficients). RESULTS:Among the 1580 workers using WittyFit, 187 (11.83%) agreed to complete the WART questionnaire. Of those, 128 completed the test-retest survey (68.4%). Acceptability found that all respondents had fully completed the questionnaire, with few floor or ceiling effects. Reliability was very good with a Cronbach alpha coefficient at .90 (internal consistency) and Lin concordance coefficient at .90 (95% CI .87-.94] with a difference on the retest of .04 (SD 4.9) (95% CI -9.6 to 9.7) (reproducibility). We identified three main dimensions (construct validity). Relationships between WART and stress and well-being confirmed its external validity. CONCLUSIONS:The French version of the WART is a valid and reliable instrument to assess work addiction with satisfactory psychometric properties. Used in occupational medicine, this tool would allow the diagnosis of work addiction and can be easily implemented in current practice.

Project description:BackgroundDespite the growing interest of the item response theory (IRT) in assessment of person abilities and functioning difficulties in screening tools, there is scarcity of research using IRT on ICF-based tools for persons with low back pain (LBP).AimTo generate and validate a parsimonious core set of ICF (PCSI) for LBP based on the IRT modelling.DesignA cross-sectional study.SettingNine hospitals in Jiangsu Province, China.PopulationWe recruited patients with LBP.MethodsAll participants completed the 78 items of the comprehensive ICF Core Set for LBP. The five-point scoring system was converted to dichotomous data with 1 as functioning/independent and 0 as impairment/dependent. Psychometric properties of the data were examined using Mokken Scale analysis and parametric item response modelling.ResultsThis study recruited 306 participants (185 females and 121 males) with LBP. The overall median age of the study participants was 50.28 (95% CI 23.34; 82.05) years. We constructed a three-parameter logistic model with 28 ICF categories (8 of body function, 18 of activities and participation, and two of body structures). The internal consistency was good with Cronbach's alpha = 0.927 and latent class reliability coefficient (LCRC) = 0.955. The model was validated by significant correlations (P<0.001) of its estimated person abilities with the Oswestry Disability Index (ODI, r=-0.41), the Roland-Morris Disability Questionnaire (RMDQ, r=-0.57), the Physical Component Summary (PCS, r=0.63), and the Mental Component Summary (MCS, r = 0.46) of 12-Item Short Form Survey (SF-12). The person abilities and item difficulties were integrated into a Wright map that offered a background for making individualized clinical decisions.ConclusionsThe PCSI of LBP with 28 categories has good construct validity and internal consistency, and is a convenient instrument for assessing functioning among persons with LBP. The IRT model provided theoretical and algorithmic support for deriving a simplified model for functioning assessment hence serving a basis for formulating rehabilitation plans in clinical practice and research.Clinical rehabilitation impactA parsimonious core set of ICF (PCSI) for LBP based on the IRT modelling provides a background for making individualized clinical decisions based on item difficulties.

Project description:BackgroundThe Mystical Experience Questionnaire (MEQ-30) and Challenging Effects Questionnaire (CEQ) are two of the most widely used, validated instruments to probe subjective effects of psychedelic drugs. However, these assessments are lengthy and can be a burden to study participants or patients if administered during acute psychedelic effects, after resolution of psychedelic effects when participants are often fatigued, or in studies with multiple other assessments. The development of briefer measures can advance research and patient assessment.Methods and materialsThis study developed and assessed the validity of brief versions of the MEQ-30 and CEQ (MEQ-4 and CEQ-7) using data collected online from individuals reporting psychedelic use with therapeutic intent in nonstudy settings (N = 1160). Respondents completed full and brief versions as well as mood questionnaires indexing mental health symptoms before their psychedelic experience and now.ResultsFull and brief version total scores showed strong correspondence for the MEQ (r = 0.89) and CEQ (r = 0.90). Brief versions also showed strong correspondence to full-scale subscale scores. MEQ and CEQ scores were higher for classic psychedelics (e.g., lysergic acid diethylamide, psilocybin) than for 3,4-Methylene-dioxymethamphetamine in this sample with both full and brief versions, consistent with previous full-version findings showing drug and dose-related differences using the MEQ. Also consistent with prior findings, higher mystical experience scores on both full and brief MEQ versions were associated with greater reductions in depression and anxiety, whereas challenging experiences on both full and brief CEQ versions showed limited association with changes in mental health variables.ConclusionThe notably strong association of brief scales with full versions combined with associations with therapeutic outcomes provide initial support for the MEQ-4 and CEQ-7. These findings, combined with substantial reductions in participant/patient burden, support the use of the MEQ-4 and CEQ-7 for a wide variety of research and patient treatment settings.
