Severity Of The Disease

Purpose.Development and validation of the severity index of lichen planus (LP). Materials and methods.At the first stage, by means of theoretical substantiation, the main parameters and signs were identified that affect the severity of the disease and the quality of life of patients, which culminated in the derivation of the final index formula, which was called the lichen area and severity index (LPASI). At the second stage, LPASI was validated during the examination of 45 LP patients who were treated in the clinic of skin and venereal diseases of the Military Medical Academy in 20182019. Determination of LPASI was carried out by five dermatovenerologists independently of each other twice with an interval of one week. The analysis of the results was carried out using STATISTICA 10.0 programs and SPSS Statistics 17.0. The Spearman Brown and Pearson correlation coefficients were used to evaluate the intra-expert and inter-expert reliability of the index, and the Cronbach's alpha coefficient was calculated to assess the internal consistency of the scale. Results.The final formula for calculating LPASI is as follows: 0.2A+2B+5С+D, where A is the area of skin lesions in percentage, B is the severity of clinical manifestations on the skin, C is the severity of clinical manifestations on the oral mucosa and D is the severity of subjective sensations. The index can range from 0 to 82. The LPASI values for the whole group (n=45) were characterized by a normal distribution of the trait (p0.05), the minimum and maximum values varied from 7.2 to 42 points, the median was 22 points, the interquartile span from 14 to 27 points. The values of the Spearman Brown and Pearson coefficients were equal to 0.91 (95% CI 0.890.99) and 0,87 (95% CI 0.860.93), which indicates the reproducibility of the results and the reliability of the index. In this case, a high consistency between the selected features within the scale (Cronbach's alpha criterion 0.93) was established. Conclusion.Objectification of the severity of the disease using LPASI should become an integral part of the clinical examination of patients. The use of LPASI will allow to control the effectiveness of prescribed therapy, as well as to compare the results of scientific research.

Limitations in hand function are common among children with cerebral palsy (CP), with almost 50% presenting an arm–hand dysfunction. However, there is no standardized assessment tool available in Italian for evaluating bimanual performance for this population. Our objective in this study was to evaluate the psychometric properties of an Italian translation of the ABILHAND-Kids (ABILHAND-Kids-IT) among children with CP. We examined internal consistency using Cronbach’s Alpha and Omega coefficients, and we investigated test-retest reliability with intraclass correlation coefficients (ICC). We performed explorative factor analysis (EFA) to investigate structural validity. We calculated Pearson’s correlation coefficients between the ABILAND-Kids IT and the Manual Ability Classification System (MACS) to assess criterion validity; and, to demonstrate the score variability of the ABILHAND-Kids-IT, we used analyses of variance (ANOVAs) to compare the 181 children with CP in this sample with their levels on the MACS. We enrolled 181 children with CP in the study. EFA confirmed a uni-dimensional scale. We obtained internal consistency on both Cronbach’s Alpha and Omega coefficient of 0.98, and a one-week test-retest reliability analysis revealed an ICC with 95% of confidence interval of .992. The ANOVA revealed significant score variability ( p < 0.01) and the Pearson correlation coefficient comparing the ABILHAND-Kids-It score with the MACS was –0.929 ( p < 0.01). We conclude that the ABILHAND-Kids-IT is valid and reliable for use with Italian children with CP.

AbstractThe lack of a Swedish patient-reported outcome instrument for eosinophilic esophagitis (EoE) has limited the assessment of the disease. The aims of the study were to translate and validate the Eosinophilic Esophagitis Activity Index (EEsAI) to Swedish and to assess the symptom severity of patients with EoE compared to a nondysphagia control group. The EEsAI was translated and adapted to a Swedish cultural context (S-EEsAI) based on international guidelines. The S-EEsAI was validated using adult Swedish patients with EoE (n = 97) and an age- and sex-matched nondysphagia control group (n = 97). All participants completed the S-EEsAI, the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Oesophageal Module 18 (EORTC QLQ-OES18), and supplementary questions regarding feasibility and demographics. Reliability and validity of the S-EEsAI were evaluated by Cronbach’s alpha and Spearman correlation coefficients between the domains of the S-EEsAI and the EORTC QLQ-OES18. A test–retest analysis of 29 patients was evaluated through intraclass correlation coefficients. The S-EEsAI had sufficient reliability with Cronbach’s alpha values of 0.83 and 0.85 for the “visual dysphagia question” and the “avoidance, modification and slow eating score” domains, respectively. The test–retest reliability was sufficient, with good to excellent intraclass correlation coefficients (0.60–0.89). The S-EEsAI domains showed moderate correlation to 6/10 EORTC QLQ-OES18 domains, indicating adequate validity. The patient S-EEsAI results differed significantly from those of the nondysphagia controls (p < 0.001). The S-EEsAI appears to be a valid and reliable instrument for monitoring adult patients with EoE in Sweden.

Abstract Purpose The purpose of the study was to validate the AQoL-8D questionnaire in the adult population of patients referred to an otolaryngology clinic. Methods AQoL-8D was translated into Polish. 463 patients (age18–80 years) with otolaryngological conditions were assessed with the AQoL-8D, SF-6D, and SWLS questionnaires. We investigated the item content-relevance, factor structure by means of Confirmatory Factor Analysis, corrected item-total correlations, Cronbach’s alpha, Pearson correlation of the AQoL-8D scores with results from SF-6D and from the SWLS questionnaires. Finally, ANOVA was used to test the AQoL-8D ability to group the HRQoL of patients in terms of their otolaryngological management type. Results The median score of item content-relevance was 5.0 for all AQoL-8D items. Confirmatory Factor Analysis revealed the following fit indices: Comparative Fit Index = 0.81; Tucker–Lewis Index = 0.80; and Root Mean Square Error of Approximation = 0.07. Cronbach's alpha for AQoL-8D dimensions ranged from 0.48 to 0.79. Mean item-total correlations over all dimensions, super dimensions, and the instrument overall were higher than 0.3. There was a significant Pearson correlation between the results obtained with AQoL-8D and SF-6D (r = 0.68), and with AQoL-8D and SWLS (r = 0.43). A one-way ANOVA showed a significant effect of management type on HRQoL as measured by AQoL-8D [F(4,458) = 6.12, p < 0.001] Conclusion AQoL-8D provides valid and reliable measures of HRQoL in patients undergoing otolaryngological treatment. Because it is a generic questionnaire, it is possible to make general comparisons of otolaryngology outcomes with those from other subspecialties.

use after also being checked by linguists. The validity analysis of the scale for the data collected was performed with exploratory factor analysis and item-total correlation tests, while the property of reliability was determined using the Cronbach’s alpha internal consistency coefficient and the stability test was carried out by determining the relationship between two applications conducted at an interval of the five weeks. The scale, which is called the “Scale for Determining the Civic-Mindedness Levels of Individuals” is a five-step Likert-type scale and consists of 27 items that can be collected under three factors. The factor names are “Openness to Criticism/Development”, “Participation/Activeness” and “Lack of Prejudice/Flexibility”. The KMO value of the scale was 0.956; and the Bartlett Test values were x2=11001.719; sd=351; p<0.000. Items in the scale accounted for 56.619% of the total variance. As a result of the confirmatory factor analysis, the χ2 value was 808.07 and the degree of freedom was 321. Χ2/df is 2.51. The fit indices of the scale were determined as RMSEA=0.067; S-RMR=0.049; NFI=0.97. The item-total corrected correlation coefficients of the items in the scale varied between 0.40 and 0.703 (p<.01). The reliability coefficient of the scale was Cronbach’s alpha at 0.954 and the stability coefficients of the items were between 0.496 and 0.674 (p<,01).

Background:One of the goals of nursing is to provide safe patient care and medical errors are one of the most important threats in this field.Therefore, the purpose of this study is to assess the status of error reporting culture and determine its relationship with demographic characteristics.Methods:This descriptive,analytical and cross-sectional study was carried out among 239 nurses of amiralmomenin and bouali hospitals. First,face validity and then content validity were performed by 15 nursing experts and the questionnaire was distributed and collected. The normal distribution of data was confirmed by Kolmogorov-Smirnov test. The reliability and construct validity were performed with Cronbach’s Alpha test and exploratory factor analysis by PCM.The status of reporting culture was determined by computing descriptive statistics and its relation with demographic variables with Pearson correlation test and logistic regression test with SPSS software version 16.Results:The content validity with CVR &CVI of 0.820 and 0.920 were confirmed. The reporting culture was favorable with a mean and standard deviation of 2.674 and 0.475.The reliability with Cronbach's alpha of 0.747 and the construct validity with a KMO of 0.727 and Significance of the Bartlett test were confirmed and 3 subscales were extracted. The relationship between age and work experience with the reporting culture with a correlation of 0.009 and 0.013 with a significant < 0.05 were rejected But with the variable of gender(=female) with a chance of 2.536 and the significant of 0.006 was confirmed.Conclusion:Developing a safety culture in hospitals by implementing various health programs improves the reporting culture,but the mental climate is undesirable and requires major steps to reduce worries and negative outcomes after reporting.The presence of female nurses in comparison with men improves the error reporting culture.Perhaps the main reason is patriarchy in Iranian culture.

Abstract Background The aim of this study was to adapt the instrument and evaluate the psychometric properties of the Swedish version of the Swallowing Quality of Care questionnaire (S-SWAL-CARE) in patients with oropharyngeal dysphagia. Methods Translation and adaptation of the original SWAL-CARE into Swedish was performed according to established international guidelines. Field testing was performed using 100 patients with oropharyngeal dysphagia due to multiple reasons such as head and neck cancer and neurologic/neuromuscular disease, who had undergone swallowing evaluation within 6 months prior to the study. The patients answered the S-SWAL-CARE, the Quality from the Patient’s Perspective (QPP) and the Swallowing Quality of Life (SWAL-QOL). Test–retest was performed in 20% of the participants. The reliability and validity of the S-SWAL-CARE were assessed by Pearson correlation coefficient and Cronbach’s alpha as well as convergent and discriminative validity, respectively. Results The field testing of the S-SWAL-CARE resulted in sufficient reliability, with Cronbach’s alpha values exceeding 0.90 for all domains. All items correlated strongly to their own domain, with weaker correlations to the other domains, indicating proper scale structure. Results also indicate sufficient convergent and discriminant validity when tested for association to the QPP domains and the SWAL-QOL Total score. The test–retest reliability of the S-SWAL-CARE demonstrated sufficient intraclass correlation coefficient (ICC) for the General advice domain (0.73) and Clinical advice domain (0.82). The ICC for the Patient satisfaction domain was lower (0.44). Conclusion The S-SWAL-CARE can be considered a reliable and valid tool to assess the dysphagia-related quality of care in a mixed Swedish dysphagia patient population.
