    INPATIENT SATISFACTION QUESTIONNAIRE: SCALE DEVELOPMENT AND RELIABILITYVALIDITY STUDY
    (2021) Kevenk, Ahmet Uğur; Yılmaz, Fatma Kantaş; Öztürk, Meltem
    Objective: The aim of this study was to develop a valid and reliable measurement instrument to determine the satisfaction rates of inpatients.Methods: This study was designed as a methodological research and the eight-step scale development principles developed by Devellis werefollowed. The sample size was calculated as 360, taking into account 10 times the number of items in the explanatory factor analysis. Exploratoryand confirmatory factor analyses were applied to the scale and the reliability coefficients, Cronbach's Alpha and Composite Reliability values,were calculated for the subdimensions obtained.Results: Since probability value was p<0.05 and Kaiser-Meyer-Olkin (KMO) value was determined as 0.939 for Bartlett's test, which wasperformed for factor analysis suitability of the results obtained from 36 items, the data set was found to be “perfectly” suitable for factor analysis.The scale was able to explain the concept of inpatient satisfaction to a large extent since the total variance explained was found to be 70.04% infactor analysis. In the confirmatory factor analysis of the scale which resulted in 32 items and five subdimensions, all of the covariance valuesdrawn between the subdimensions were significant (p<0.05). Factor loadings of items were within the range of 0.62-0.95. Cronbach's Alphareliability score of the Inpatient Satisfaction Questionnaire (ISQ) was found to be 0.911 for the whole scale.Conclusion: The questionnaire that was developed exhibited a high level of reliability and validity. We suggest that it is suitable for measuring thesatisfaction of inpatients, and the data obtained will aid and guide in the improvement of healthcare facilities.

    Inpatient satisfaction questionnaire: scale development and reliabilityvalidity study

The scale was able to explain the concept of inpatient satisfaction to a large extent since the total variance explained was found to be 70.04% in factor analysis. In the confirmatory factor analysis of the scale which resulted in 32 items and five subdimensions, all of the covariance values drawn between the subdimensions were significant (p<0.05). Factor loadings of items were within the range of 0.62-0.95. Cronbach's Alpha reliability score of the Inpatient Satisfaction Questionnaire (ISQ) was found to be 0.911 for the whole scale.

    Is there a relationship between blood lipids and lumbar disc herniation in young Turkish adults?
    (2017-06-30) Kevenk, Ahmet Uğur
    Abstract Introduction: Atherosclerosis might diminish the nutrient supply to intervertebral discs (IVD), leading to disc herniation. Therefore, there is interest in determining the possible association between the blood lipid profile and lumbar disc herniation (LDH). We aimed to evaluate the association between blood lipids and LDH in a homogeneous group of patients, controlling for age- and sex-specific effects. Material and methods: This is a case-control study which consisted of 100 individuals (mean age: 41.25 ±9.09; 50 men and 50 women), classified into two groups, as follows. Group I (G-I) consisted of 50 patients who underwent surgery for symptomatic LDH, while group II (G-II) consisted of 50 patients with nonspecific complaints of a headache, but with no previous history of back and/or leg pain, recruited among patients admitted to the outpatient clinic at the time of the study, and whose age and sex were matched to the study group. Total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), fasting blood glucose, and hemoglobin A1c levels were measured. The TC/HDL-C ratio was calculated. Blood pressure, waist circumference, body mass index, and the history of smoking were included in the analysis. Results: The mean values of the TC, TG, LDL-C, HDL-C levels and TC/HDL-C ratio were 198.38, 132.76, 131.9, 40.38 mg/dl and 5.09, respectively. No statistically significant relationship between the blood lipid profile and LDH was identified in this population. Conclusions: Blood lipid levels in this young adult Turkish population did not predict LDH, and may not be a leading cause of IVD ischemia and IVD degeneration.
