The levels of agreement between self- and parent/proxy-reports of anxiety and depressive symptoms in pediatric epilepsy were evaluated. Data were drawn from 56 pairs of children with epilepsy and at least one parent. Anxiety symptoms were assessed using the Screen for Child Anxiety Related Emotional Disorders (SCARED), while depressive symptoms were assessed using the Mood and Feeling Questionnaire (MFQ). Moderate to substantial levels of agreement between raters when reporting various anxiety symptoms, such as panic/somatic disorder, generalized anxiety disorder, separation anxiety disorder, social phobia, and school phobia symptoms, were observed. Levels of agreement between raters were substantial when reporting depressive symptoms. However, levels of agreement differed if raw or criterion-referenced questionnaires' scores were used. In case of using raw questionnaire scores, substantial agreements appeared when reporting overall anxiety and depressive symptoms. On the other hand, moderate agreements appeared when reporting particular anxiety symptoms with raw questionnaire scores or when using criterion-referenced scores that indicate the presence of certain symptoms in a clinical range. Therefore, it is advisable to include both raters when assessing anxiety and depressive symptoms in pediatric epilepsy. © 2012 Elsevier Inc.

Background We provided preliminary psychometric data for the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Head and Neck Module, updated version (QLQ-H&N43) from a group of Serbian laryngectomized patients. Methods The study included 170 subjects. The QLQ-H&N43 is a 43-item questionnaire, with 12 multi-item scales and 7 single-item symptom scales. All subjects also completed the Quality of Life Questionnaire-Core 30-questions (QLQ-C30). Results Good internal consistency (Cronbach's α of above 0.7) was found for 5 of the 7 scales. All QLQ-H&N43 scales correlated negatively as predicted with all QLQ-C30 functioning scales. The correlations with the QLQ-C30 symptoms supported discriminant validity, with only one exception: the head and neck social eating scale overlapped with the QLQ-C30 pain scale. For 14 of 19 QLQ-H&N43 scale scores, significant known-group differences were observed between those who differ in type of laryngectomy, adjuvant therapy, or 5-year survival. Conclusion Preliminary evidence suggests that a great majority of the QLQ-H&N43 scales have acceptable internal consistency and promising construct validity, but more research studies are needed with other cancer groups to extend these findings. © 2015 Wiley Periodicals, Inc..

Purpose: To evaluate the psychometric properties of the Serbian set of the KIDSCREEN questionnaires: KIDSCREEN-52, KIDSCREEN-27, and KIDSCREEN-10 index. Methods: The study included 330 children (8-18 years) and 314 parents. All completed the KIDSCREEN and KINDL questionnaires. Psychometric analyses included internal consistency reliability (Cronbach's coefficient), criterion, convergent and discriminant validity, and agreement between children and parents (the intraclass correlation coefficient - ICC). Results: Cronbach's α of 0.7 and above was found for all except for the self-perception scale of the KIDSCREEN-52, being 0.58 for the child and 0.63 for the parent version. Correlations between similar scales in the KIDSCREEN and KINDL were substantial (ranging 0.45-65) and higher than correlations between theoretically different scales. Moderate to excellent agreement existed between children's and parents' ratings in all KIDSCREEN scales (ICC ranged 0.44-0.63), except for the moods and emotions from the longer (ICC = 0.34) and the social support and peers from the shorter version (ICC = 0.38). Conclusions: Levels of internal consistency reliability and validity of all KIDSCREEN questionnaires in Serbian are appropriate, as well as agreement between children's and parents' ratings. © 2012 Springer Science+Business Media Dordrecht.

Purpose: Children with juvenile idiopathic arthritis (JIA) are at an increased risk of developing emotional problems. This study evaluated the associations between levels of depressive and anxiety symptoms and health-related quality of life (HRQOL) in these children. Methods: Sixty-seven children with JIA, together with one parent, participated. Anxiety symptoms were identified using the Screen for Child Anxiety Related Emotional Disorders Questionnaire (SCARED), while depressive symptoms were identified using the Mood and Feeling Questionnaire (MFQ). The Pediatric Quality of Life Inventory (PedsQL) was used for HRQOL assessments. Using hierarchical multiple-regression analysis, demographics, clinical factors, and pain were control variables, while anxiety (the SCARED score) and depressive symptoms (the MFQ score) were HRQOL (the PedsQL score) predictors. Results: The regression model emerged with specified variables explaining 63 % of the variance in the PedsQL score (F = 11.92, p < 0.01) among children. Among parents, the same set of variables accounted for 49 % the variance (F = 6.99, p < 0.01). The MFQ score, but not the SCARED, added most to the variance. Conclusions: Depressive symptoms, but not anxiety, accounted for substantial variability in levels of HRQOL when considered with demographics, clinical factors, and pain. Thus, screening for depression needs to be considered as a part of multimodal assessment and treatment approaches in JIA. © 2012 Springer Science+Business Media B.V.

The objectives of this study were to translate into Serbian the Health-Related Quality of Life Measure for Children with Epilepsy (CHEQOL-25) and to provide preliminary data on its measurement properties. Translation, cultural adaptation, and pretesting were performed first, followed by evaluation of several reliability aspects of this version administered to 50 children with epilepsy and their parents. The mean scores of the CHEQOL-25 subscales ranged from 12.2 to 14.4 for children and from 12.4 to 15 for parents (possible range: 5-20). The internal consistency coefficients of the subscales ranged from 0.11 to 0.87. Between the children's and parents' reports, there was a moderate level of agreement (0.43-0.57). It was concluded that the Serbian version is a feasible measure, all subscales except one demonstrate sufficient reliability, and a parent form could be used as a proxy measure. © 2009 Elsevier Inc.

This study aimed to analyze the measurement properties of the Health-related quality of life questionnaire for polycystic ovary syndrome (PCOSQ-50) in a sample of Serbian women with polycystic ovary syndrome (PCOS). Seventy-six women with PCOS from an endocrinology clinic and 28 healthy women participated between October 2016 and March 2017. The measure was rigorously translated and culturally adapted into Serbian. Psychometric evaluation included descriptive analysis, internal consistency (Cronbach’s alpha coefficient), test-retest reliability (intraclass-correlation coefficient–ICC) and construct validity testing. Cronbach’s alpha coefficient ranged from 0.67 to 0.96 for domain scales of PCOSQ-50 scores, while the ICCs for test-retest reliability for these domains ranged from 0.66 to 0.89. Women with PCOS had significantly lower scores than healthy women for hirsutism, obesity and menstrual disorders and the total PCOSQ-50 scale score (p ≤ 0.03), but not for the psychosocial and emotional, fertility, sexual function, and coping scales. These results show that the Serbian PCOSQ-50 measure is acceptable and could produce reliable and valid assessments of PCOS-related quality of life for at least four out of seven domains. Considering that validity testing is an iterative process, additional work is needed before the whole measure is used in routine clinical practice. © 2019, © 2019 Taylor & Francis Group, LLC.

Multiple sclerosis (MS) is a chronic, autoimmune, inflammatory, demyelinating disease of the central nervous system. MS is increasingly recognized in the pediatric population, and it is usually diagnosed around 15 years of age. The exact etiology of MS is still not known, although autoimmune, genetic, and environmental factors play important roles in its development, making it a multifactorial disease. The disease in children almost always presents in the relapsing-remittent form. The therapy involves treatment of relapses, and immunomodulatory and symptomatic treatment. The treatment of children with MS has to be multidisciplinary and include pediatric neurologists, ophthalmologists, psychologists, physiotherapists, and if necessary, pediatric psychiatrists and pharmacologists. The basis of MS therapy should rely on drugs that are able to modify the course of the disease, i.e. immunomodulatory drugs. These drugs can be subdivided into two general categories: first-line immunomodulatory therapy (interferon beta-1a, interferon beta-1b, glatiramer acetate) and second-line immunomodulatory therapy (natalizumab, mitoxantrone, fingolimod, teriflunomide, azathioprine, rituximab, dimethyl fumarate, daclizumab). Treatment of relapses involves the use of high intravenous doses of corticosteroids, administration of intravenous immunoglobulins, and plasmapheresis. We summarize here the current available information related to the etiology and treatment options in MS. Early administration of immunomodulatory therapy is beneficial in adults, while more studies are needed to prove their effectiveness in pediatric populations. Therefore, pediatric MS still represents a great challenge for both, the early and correct diagnosis, as well as its treatment. © 2016, The Author(s).

Introduction Measures of health-related quality of life (HRQOL) are considered to be more comprehensive in health outcome assessments than scales assessing only the degree of neurological deficit. Objective The aim of the study was to evaluate HRQOL and its correlates among adolescents with multiple sclerosis (MS) in Serbia. Methods Demographic, clinical, and patient-reported outcome data were collected for 21 adolescents with MS, aged 14–18 years. The KIDSCREEN measure was used for HRQOL assessment. Anxiety and depressive symptoms were identified by the Revised Child Anxiety and Depression Scale (RCADS), while fatigue was assessed by the Paediatric - Functional Assessment of Chronic Illness Therapy-Fatigue (PedsFACIT-F). Results Compared to the national data for healthy adolescents, the scores for a domain assessing physical well-being were significantly lower among adolescents with MS. Five (23.8%) adolescents had the RCADS scores within the clinical range. The age of the disease onset significantly correlated with the social and school domain. Neurological impairment correlated negatively with self-perception, school environment, and social acceptance domain. Fatigue significantly correlated with physical and psychological domains. The RCADS scores and the disease duration correlated negatively with the majority of the KIDSCREEN scores. Conclusion In adolescents with MS physical HRQOL domain is most likely to be compromised, whilst functioning and well-being in other domains are relatively preserved. Severity of the disease, its duration, and fatigue, with increased anxiety and depressive symptoms, are significant HRQOL correlates. © 2016 Elsevier B.V.

Background: Vertebral fractures could lead to reduced physical, social and mental functioning, and loss of personal independence. Therefore, during the treatment of osteoporosis, it has become necessary to examine the changes in everyday functioning, well-being and health related quality of life (HRQOL). To that effect, this study aims to translate, culturally adapt, and validate the Serbian version of Quality of Life Questionnaire of the European Foundation for Osteoporosis (QUALEFFO-41) for patients with vertebral fractures.Methods: Nine female patients with osteoporosis participated in the pre-validation study. A validation, case-control study included two groups of female patients: one that consisted of 50 female patients with osteoporosis, and with at least one vertebral fracture, and another one that consisted of 50 control patients with osteoporosis but without fractures. They completed the QUALEFFO-41 and the EuroQol group questionnaire with five dimensions (EQ-5D) twice within a month. The validation study examined internal consistency, concurrent validity, test-retest reliability, sensitivity and specificity.Results: During the pre-validation study, three of the items in the QUALEFFO-41 were slightly changed. Afterwards, during the validation study, the statistically significant differences (adjusted for: age, duration of menopause, current employment and marital status) in the mean values of all domains and total scores between the groups were noted. For the case group, the internal consistency of the QUALEFFO-41 domains and of total questionnaire was above 0.70. The test-retest reliability was tested by the intraclass correlation coefficients (ICC) that were in range 0.87 - 0.96 for the case, and 0.15 - 0.83 for the control group. Correlations between the total scores of the QUALEFFO-41 and the EQ-5D health state value, for both groups were negative and statistically significant (r = -0.78, p<0.001 and r = -0.73, p<0.001, respectively). The QUALEFFO-41 had a better prediction of the value of HRQOL of cases compared to the generic questionnaire EQ-5D (the AUC difference was 0.099, p = 0.013).Conclusions: The Serbian QUALEFFO-41 version is reliable, valid, sensitive and predictive for examinations of HRQOL in patients with prevalent vertebral fractures and can be used in further studies. © 2012 Tadic et al.; licensee BioMed Central Ltd.
