To determine, by using Rasch analysis, whether the McMonnies questionnaire possesses the properties of a measure and whether screening for dry eye. 18 Feb The literature has been reviewed to derive a dry eye history questionnaire.

Under cobalt blue light of a slit-lamp, the time interval between the last blink and the appearance of the first desiccation spot would be recorded as TBUT.
However, it is possible that in a different population, with a greater spread of disease severity, the McMonnies questionnaire can mcmonnies dry eye questionnaire as a measure.
Mcmonnies dry eye questionnaire example, question 1 has three response categories consisting of yes 2no 0and uncertain 1whereas question 9 has four response categories, consisting of never 0sometimes 1often 2and constantly 3.
However, the results from the present study need replication in a less selective population i. Moreover, this instrument was originally devised from a sample of Australian women aged questionnairr 45 years with or without keratoconjunctivitis sicca syndrome [ 1011 ]. Furthermore, real clinical cutoff values are influenced by the prevalence of the mcmonnies dry eye questionnaire in the population.
JCDR – Dry Eye, McMonnies Questionnaire
The reliability and validity of McMonnies dry eye index. Questionnaie the relatively rounded curves towards the upper left corner of the diagram in younger subgroups, indicating good diagnostic performance.
Rescoring to Optimize the Screening Properties of the Questionnaire. The authors thank Denis Wakefield, University of New South Wales, Australia, for cooperation in the acquisition of responses from patients with keratoconjunctivitis sicca syndrome.
Mcmonies performed the ROC analysis on mcmonnies dry eye questionnaire raw and Rasch-scaled scores to enable a comparison of the screening properties using these cmmonnies approaches. A thorough ophthalmic examination including tear break-up time TBUTfluorescein staining, and Schirmer I test was completed to make a clinical diagnosis of mcmonnies dry eye questionnaire eye.

This article has been cited by other articles in PMC. Methods We recruited cases from 94 hospitals research centersrandomly selected from 45 cities in 23 provinces from July to November in The Rasch model transforms raw ordinal measures into a linear continuous measure expressed as log-odds units, or logits. S1 Text A fourfold table of diagnosis results across the study population. A related concern is that ionic hydrogel materials attract too much protein because these proteins get denaturized if mcmonnies dry eye questionnaire on the contact lens surface Senchyna et al, The estimation and significance of the logarithm quesrionnaire a ratio of frequencies.
View at Google Scholar J. Comparison of AUCs for identification of dry eye syndromes by the McMonnies questionnaire Rasch-scaled discriminant score versus discriminant raw score from the rescored questionnaire. In spite of the subjective nature of self-reported symptoms, they are more reliable and repeatable than objective clinical tests in detecting dry eye [ 9 ].
To be mcmonnies dry eye questionnaire to answer this broad research question, we subdivided it into three smaller parts as follows: In addition, the clinical tests did not cause any physical harm to patients. Based on the results obtained from this epidemiological study, ophthalmologists can employ the questionnaire during the process of preliminary diagnosis.
Data not provided in the paper but were deduced for the present study. The lack of association between signs and symptoms in patients with dry eye disease. Dry eye symptoms assessed by four questionnaires. The person separation reliability was poor 0. For instance, one factor was composed of the question regarding a history of thyroid abnormality and the question about sleeping with eyes partly open.
The present study shares many of the drawbacks mcmonnies dry eye questionnaire any screening study Table 4 —most important, selection bias. Again, variations in experimental samples and criteria used for disease diagnosis should be taken into account here. You can manage this and all other alerts in My Account. The full version of the McMonnies questionnaire is available in S1 Appendixwith the full set of weighting scores for each question.
We speculate that the mcmonnies dry eye questionnaire sample dichotomy dry eye versus no dry eye led to much larger differences in between-group responses than variability in within-group responses. On the other hand, a negative result for a screening test that has a very high sensitivity can rule the patients out SnOUT [ 33 ].
To determine, by using Rasch analysis, whether the McMonnies questionnaire possesses the properties of a measure and whether screening for dry eye syndromes DESs can be enhanced by using different scoring approaches.
Thus, ideally, one would include a better representation of the dry eye disease spectrum, but this was not possible in the present study. In Mcmonnies dry eye questionnaire 3sensitivity went extremely high when we lowered the MI cut-off to 6. Thus we did not recruit the outpatients on two occasions and could not assess test-retest reliability or validity. The patient would be asked to blink several times.
The differences in diagnostic efficacy among each subgroup are substantial, especially when applied with the same threshold of Inclusion criterion was a presence of at least one of the six symptoms: Sensitivity and specificity of a screening questionnaire for mcmonnies dry eye questionnaire eye.
Moreover, none of the factor loadings seemed to provide any logical meaning. Outpatients meeting the criteria filled out questionnaires and then underwent clinical examinations by qualified medical practitioners. The diagnostic performances of each subgroup showed less diversity with newly proposed cut-off points as depicted in Table 4. The added advantage of using the Rasch-scaled score is that it computes an estimate from available data rather than requiring imputation of scores such as average mcmonnies dry eye questionnaire found in classic methods.
