Abstract Background Ecological literacy aims to build up a framework of view that identifies the association with nature and enhances the improvement of new areas to produce sustainable lifestyles. Today, this concept has become one of the important requirements for a sustainable community. The aim of the study was to develop the Ecological Literacy Scale (ELS) to determine the ecological literacy of primary school students. Methods This methodological study carried out in 233 primary school 4th grade students in an eco-school in the 2019-2020 academic year. By using literature 91 questions was collected including water, energy, transport and air, biodiversity, purchasing and waste topics which were main issues of ecological footprint. After taking expert opinions, a scale that consists of 32 questions and scored as I agree:3, undecided:2, I disagree:1 and was created named ELS. In order to evaluate the reliability of the scale, item total score correlation and internal consistency (Cronbach's alpha) analyzes and exploratory factor analysis was used for construct validity. Results Of the 52.8% students were male and their age ranges from 8-11, the mean was 9.5±0.6. After the scale development study, the scale consisted of 19 items and unidimension. Scale items explain 27.37% of total variance and factor loadings ranged from 0.42-0.64. The Cronbach's alpha coefficient was 0.846 for the scale. In the last form of the scale, the score that can be taken from scale range 19-57. It was accepted that by increasing of the score, ecological literacy level was increased. The mean score of the students was 51.73 ± 5.39 and the median was 53.0. Conclusions Ecological literacy could be considered as high level for primary school students in eco-school. ELS was found to be a valid-reliable tool for assesing ecological literacy in primary school students. Key messages Ecological literacy is an issue that students should be informed from the primary school period. In the literature, ELS seems the first scale about ecological literacy for primary school students and needs to be tested in large groups of students.

Abstract Background Antiretroviral therapy (ART) has the most effective treatment for people with HIV, but its effectiveness depends on the individual medication adherence. Morisky Medication Adherence Scale (MMAS-8) is one of the most widely used scales to assess patient adherence. Thus, we aimed to validate a Portuguese version of MMAS-8 and determine its psychometric properties in HIV positive patients. Methods A cross-sectional survey was conducted in Centro Hospitalar Universitário São João (Porto, northern Portugal) at the infectious diseases department. After authorization to use the scale - granted by the author - and, a standard forward-backwards procedure to translate MMAS-8 to Portuguese, the questionnaire was applied to 233 patients with HIV doing ART. Reliability was assessed using Cronbach's alpha and test-retest reliability. Three levels of adherence were considered: 0 to < 6 (low), 6 to < 8 (medium), 8 (high). Results In the studied sample, the mean age was 45.03 years (SD = 11.63), 80.3% men, 19.3% women and 1 transgender, and 53.8% had ≤9 years of education. The mean number of prescribed ART per patient was 1.76. The mean score for the medication adherence scale was 7.29 (SD = 6.74). For the reliability analysis, 12 patients were excluded due to missing data (n = 221). Regarding the level of adherence, 22.5% were low adhering, 71.6% medium and 5.9% high. Corrected item-total correlations showed that 1 item does not correlate very well with the overall scale and was dropped. Scale reliability analysis for the remaining 7 items revealed an overall Cronbach's alpha of 0.661. Women had a protective effect on adherence (OR = 0.31;95%CI:0.15-0.66). Number of years doing ART, age of participants, and type of residence didn't show to be correlated with adherence. Conclusions MMAS-8 is a reliable and valid measure to detect patients at risk of non-adherence. A satisfactory Cronbach's alfa (0.661) was obtained. In general, adherence to medication was medium or high. Key messages This scale can be applied nationwide in other different hospitals, as it could serve as a tool for measuring adherence to ART that can allow for better health care to the ones that are low adhering. A Portuguese version of the MMAS-8 was created for measuring adherence to ART that maintained a similar structure to the original MMAS-8 and good psychometric properties.

Smartphone Use

Introduction: The use of smartphone among children and adolescents has been increasing steadily over the past decade and is becoming a cause of concern for parents and healthcare professionals alike. Excessive use of smartphone could make a child vulnerable to develop addictive behaviour leading to decrease in academic performance and impairments in social and personal environment. Early identification is key to addressing this issue and although there are scales to measure smartphone addiction in adults, there are no scales to measure smartphone use in children objectively. Aim: To construct a smartphone addiction scale for children that can be administered to parents. Materials and Methods: A set of statements were created to assess smartphone addiction in children. Initially, 43 statements were selected after identifying its content validity and face validity and the scale was administered to parents of children in the age group of 3-17 years after obtaining informed consent from the parents. The construct validity was examined by the exploratory factor analysis. The screen plot of ordered eigen values of a correlation matrix was used to decide the appropriate number of factors extracted. A factor loading of >0.30 was used to determine the items for each factor. Intra-class correlations were calculated for the test-retest reliability, and Cronbach's alpha was calculated for the internal consistency. The final questionnaire contained 24 statements across six subdomains of smartphone addiction and it was administered to a small sample group of 65 parents of children aged 3-17 years and the data was used to test for reliability and validity of the scale. Results: Alpha correlation for the Smartphone Addiction Scale for Children-Parent (SASC-P) ranged from 0.670 to 0.823. The intrinsic validity for the domains was calculated using Cronbach’s alpha and it ranged from 0.819 to 0.907 for the domains and was 0.972 for the whole questionnaire. Thus the scale was found to be reliable and valid for use in children and adolescents. Conclusion: The SASC-P has good reliability and validity and can be used to measure smartphone use in children and adolescent.

Abstract Background Coping strategies are essential in the cancer management/recovery process and show an integral part in patients with cancer globally. In Sri Lanka, validated scales to measure coping are scarce. This study was examined the Sinhalese version of the Brief COPE for its psychometric properties. Methods This scale is self-administered (28 items) and consists of adaptive and maladaptive coping strategies; divided into 14 subscales. Cancer patients were registered ‘first come - first serve’ basis using their appointment register at the Radiotherapy Unit, Oncology ward, Teaching Hospital, Karapitiya, Galle, Sri Lanka. They were requested to complete the Sinhalese version of the Brief COPE and demographic details. Test-retest reliability was checked using the same subjects two weeks later. Factorial validity was performed using exploratory factor and principal component analysis. Results were regarded as statistically significant if p < 0.05. Results The mean (±SD) age of the sample was 61(±12) years. The mean adaptive coping (±SD) and maladaptive coping were 37.50 (±8.14) and 17.10 (±2.44) respectively. The internal consistency of the overall scale was good (Cronbach’s alpha - 0.819). Adaptive and maladaptive coping showed a high Cronbach’s alpha (0.861 and 0.396). The test-retest reliability was found to be 0.66. The Sinhala version of BC was found to have a negative correlation with the CES-D scale but was positively correlated with the WHOQOL-BREF questionnaire. Seven factors were extracted. Conclusion The Sinhala version of the Brief COPE is a valid and reliable tool to assess coping strategies among patients with cancer. The findings of this study would let the health authorities get an understanding of coping strategies among patients with cancer; and the impact on cancer victims and family members to relieve their suffering.

Abstract Background: Parents of children with autism spectrum disorder (ASD) are known to poorer quality of life. The Quality of Life in Autism Questionnaire (QoLA) is a commonly used instrument for measuring the quality of life in parents of children with ASD. The aim of this study was to evaluate the reliability and validity of the QoLA in Iranian mothers of children with ASD.Methods: The sample of this methodological study consisted of 88 mothers of children with ASD in Arak, Iran. The data were collected using convenience sampling method between September 2019 and January 2020. A battery of questionnaires was administered to mothers which included the QoLA, Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), and Perceived Stress Scale-4 (PSS-4). Factor structure and internal consistency of the QoLA were examined via confirmatory factor analysis (CFA) and Cronbach’s alpha, respectively. Convergent validity was examined by relationship with WHOQOL-BREF, PHQ-9, GAD-7 and PSS-4.Results: The mean total scores of QoLA Part A and Part B were 86.50 (SD=13.89) and 61.41 (SD=18.21), respectively. Both subscales exhibited good internal validity (with Cronbach’s alpha of 0.899 and 0.950 for Part A and Part B, respectively). The convergent validity of both subscales of QoLA was proved via moderate to strong correlations with measure of the WHOQOL-BREF. In addition, both QoLA Part A and Part B scores were negatively correlated with measures of PHQ-9, GAD-7, and PSS-4. The confirmatory factor analyses provided evidence for unidimensionality of both subscales of QoLA.Conclusion: The Persian version of QoLA displays satisfactory reliability and validity in Iranian mothers of children with ASD.

Pain Subscale

Abstract Background The Harris Hip Score (HHS) is a widely used Patient-Related Outcomes score. It measures pain and function levels in patients with hip pathologies. Objectives The main objective of this study is to translate and culturally adapt the HHS into Arabic, and to further assess the reliability and validity of translated version Material & Methods 110 patients participated in this survey. The internal consistency tests were performed using Cronbach’s alpha. Test-retest reliability (intra-correlation coefficient), convergent construct validity, convergent validity, floor & ceiling effects and responsiveness was also calculated. In order to measure the level of agreement, Bland-Altman Plot, forest Plots are performed. Results Test reliability for the first testing situation - calculated using Cronbach's alpha - was 0.98 for the pain subscale, 0.98 for the stiffness, and 0.99 for the physical function subscale. For the second testing, reliability was 0.99, 0.97, and 0.99 (pain, stiffness, and physical function, respectively). This only proves that WOMAC is an instrument with good reliability. Same calculation of Cronbach’s alpha was essential to testing the reliability of the Harris Hip Score. For each of the three testing occasions the reliability was very good or excellent – α 1 = 0.92, α 2 = 0.91, and α 3 = 0.90. Intra-class correlation coefficient was good with the score of 0.76 (95% CI 0.44-0.88). Conclusion Overall, Arabic version of HOOS could be used as diagnostic tool for patients with hip problems, when it comes to information about the overall condition of the patient, especially about the improvement or deterioration, however, it is important to be cautious using HHS when the change magnitude of patient’s condition is investigated, since there is a potential probability that the level of improvement of the patient’s condition will be overestimated by HHS.

Objective: The aim of the present study was to examine the reliability and validity of the short form of the Reynolds Adolescent Depression Scale (RADS-SF). Method: A sample of 9567 randomly selected New Zealand secondary school students participated in the Youth2000 Health and Wellbeing Survey that included the full-length version of the RADS. The reliability and validity of the subset of items that make up the RADS-SF and its comparability to the original version were assessed using Cronbach's alpha, kappa statistics, correlations between the two versions of the instrument, confirmatory factor analysis and correlation to other questions in the survey considered likely to be associated with depression. Results: The RADS-SF had Cronbach's alpha of 0.88, was strongly correlated (0.95) to the RADS, had acceptable fit for the data (χ2=2823.27, df=35, comparative fit index=0.96, root mean square error of approximation=0.092, 90% confidence interval=0.089–0.095, standardized root mean square residual=0.042), showed configural invariance across gender, age and ethnic groups, and was strongly correlated with other depression-related questions, such as suicidal ideation (r=0.48). While the overall agreement for classification of depression by the two scores was good (κ=0.75), a higher percentage of students were classified as having depressive symptoms using the recommended RADS-SF cut-off point of 26 compared with the RADS criteria. Conclusions: The RADS-SF was found to have acceptable reliability and validity and to have psychometric properties comparable to the RADS in a large population of New Zealand adolescents.

Motivation To Participate

This study aims to investigate the relationship between aggression and sports participation motives of Sports High School students in Adıyaman, Kahramanmaraş, and Malatya provinces in Turkey. 575 Sports High School students, including 385 males and 190 females, participated in our research. Surveys used to measure variables included a 30-item sports participation motivation scale a 30-item “aggression inventory”. Reliability and validity studies of the sport participation motive scale were done by Gill et al, and it was determined that Cronbach's alpha coefficients were between 0.30 and 0.78 for the sub-dimensions. The Cronbach's alpha internal consistency coefficient of the aggression scale was calculated as .83. According to our findings, there was a moderately positive relationship between assertiveness, which is the sub-dimension of aggression, and competition, and friends, which is the sub-dimension of the motivation to participate in sports. A moderately significant negative correlation was found with the sub-dimensions of aggression and entertainment, which is the sub-dimension of the motivation to participate in sports. A moderately significant positive relationship was found with destructive aggression, which is the sub-dimensions of aggression, and success and status, and competition, which are the sub-dimensions of participation in sports.
