Development and validation of a questionnaire for assessing the determinants that predict household recycling (ReDom Questionnaire).

The growing tendency towards 'urbanization' is promoting an increase in resource consumption and waste generation, which requires proper waste separation management with active participation of the population. To this end, it is essential to know the personal modifiable factors that predict recycling. The primary aim of the present study is to develop and evaluate the psychometric properties of a Spanish language questionnaire designed to measure determinants of household waste separation for recycling purposes (ReDom Questionnaire). A cross-cultural adaptation, translation and psychometric evaluation was undertaken of an extant questionnaire originally developed in Swedish, and the resultant Spanish questionnaire was then subjected to reliability and validity testing. The questionnaire was developed using survey data from 759 respondents and 33 participants performed the retest to assess reliability. The resultant 'ReDom Questionnaire' is composed of three factors that draw on relevant elements of the COM-B framework: motivation (seven items), physical opportunity (three items) and social opportunity (three items). The accuracy of the scores is adequate both in terms of internal consistency (factorial weights >0.60; comparative fit index = 0.994; root mean square error of approximation = 0.049; root mean square residual (RMSR) = 0.053) and reliability (Pearson correlation >0.65; Cronbach's alpha >0.75). In conclusion, the Spanish ReDom Questionnaire showed adequate psychometric properties and appears useful for assessing the determinants of household waste separation.

The "Breast-4Y" web app for breast cancer prevention at young age: Development, evaluation, and validation.

Background: Improving knowledge of risk factors, signs and symptoms positively influence an individual's intention to acquire healthy lifestyle behaviors to prevent breast cancer, to identify breast cancer risk early and seek health advice early. The aim of the present study was to develop and to assess the usability and quality of a web-app (Breast-4Y) designed specifically for younger women to improve their knowledge about breast cancer risk factors and symptoms as well as protective behaviors to reduce their risk. Methods: The development of the Breast-4Y web-app, based on Health Belief Model and the Behaviour Change Wheel, comprised four steps: i) analysis of scientific literature regarding breast cancer risk factors, symptoms and preventive lifestyle behaviors; ii) design of web-app; iii) content review by experts; iv) quality and usability assessment by the end-users (n = 20). Web-app usability was evaluated using the Spanish version of the System Usability Scale for the Assessment of Electronic Tools and the quality using the Spanish version of uMARS. Results: The contents were rated 4.25 or above, indicating high content quality. The mean usability score was 84.9 (SD 12.4), the mean rating for objective quality and subjective quality dimensions mean were 4.2 (SD 0.4) and 3.4 (0.777) respectively, indicating excellent usability and quality. Positive associations (p < .05) were observed between numbers of app used and attitudes to change (r = 0.479), and intention to change (r = 0.539). Strong positive associations (p < .001) were also observed between usability satisfaction and attitudes to change (r = 0.584), intention to change (r = 0.656), and help-seeking (r = 0.656). Conclusions: This study provided evidence that Breast-4Y has adequate contents, high quality, and usability. Breast-4Y can be tested in pragmatic trials to assess their effectiveness to reduce the risk of breast cancer, raise women's awareness of breast cancer risk factors, increase women's knowledge of breast cancer symptoms, and adopt protective lifestyle behaviors.

Nutritional content and quality of processed foods and beverages advertised near schools in three cities in the north of Spain.

The advertisement of food and beverages on television and social media has been widely assessed, evidencing its powerful influence on children's dietary patterns and the development of childhood obesity. However, there is a gap in the evidence about advertisements near schools. The aim of this study was to describe and classify the nutritional quality and information of processed foods and alcoholic and non-alcoholic beverages advertised near schools in three cities in the north of Spain. A descriptive analysis was performed from September to December 2021 in the cities of Oviedo, Gijón and Avilés in the Principality of Asturias (Spain). The nutritional quality and information of processed foods or beverages advertised within a 500 m radius of schools were assessed. The Nutri-Score system was used for the classification of the nutritional quality of products and nutritional information, calories, fat, saturated fat, carbohydrates, sugars, protein and salt in 100 g or ml of each product was calculated. A total of 73.5% of the products were classified as "foods to eat less often and in small amounts," and 22.6% and 46.3% were classified as D or E, respectively, according to the Nutri-Score system. Finally, 57.5%, 56.4% and 78.5% of the products showed a medium to high content of fat, saturated fat and sugar, respectively. In conclusion, the food and drink advertisements surrounding schools in the assessed cities promote many products of low nutritional value, rich in fat, saturated fat and sugars, which have high obesogenic potential.

Evaluation of Water Intake in Spanish Adolescent Soccer Players during a Competition.

An optimal state of hydration is essential to maintaining health. The objective of this cross-sectional study was to evaluate the water intake of adolescents aged 12 to 16 years and their hydration level during an official soccer match. Three hundred and six players participated in the study (N = 306). Their water intake was recorded and the level of hydration was evaluated using the density of urine as an indicator. Weight measurements were made before and after the match. Water intake control, urine collection and analysis, and the recording of minutes played were carried out after the match. The average weight loss was 746.2 g (SD: 474.07; p < 0.001), with 36.5% with less than 1% loss and 23.3% with more than 2% loss. The mean volume of water ingested was 229.35 ml (SD: 211.11) and a significant correlation was observed between minutes of activity (ρ-value = 0.206; p < 0.001), environmental humidity (ρ-value = - 0.281; p < 0.001), and temperature (ρ-value = 0.200; p < 0.001). The sweat rate was 0.69 l/h (SD: 0.56) and it was significantly associated with playing time (ρ-value = -0.276; p < 0.001). The mean urine density was 1.019 (SD: 0.007), with 64.9% of youth athletes showing dehydration (≥ 1.020). An association was observed between dehydration and activity time (U- value = 4.124; p < 0.001). Approximately 10% of the participants stated that they had not drunk any water during the match. In conclusion, it is necessary to establish individual hydration guidelines based on personal, environmental and activity-related factors, as well as establish a minimum volume of fluids to consume.

Psychometric Properties of the Spanish Version of Breast Cancer and Lymphedema Symptom Experience Index.

BACKGROUND: Lymphedema is a common late and chronic adverse effect of breast cancer treatment. This study aimed to translate and evaluate the psychometric properties of the BCLE-SEI Spanish version with Spanish-speaking breast cancer patients. METHOD: 286 patients were recruited (2018 to 2020), from the Hospital Universitario Central de Asturias. Data analysis included descriptive statistics; internal consistency and test-retest reliability; principal component analysis and exploratory factor analysis; average variance extracted; and receiver operating characteristic curves. RESULTS: No semantic modifications to items were needed. The scores of the instrument demonstrated excellent internal consistency (Cronbach´s alpha = .95-.97; McDonald´s omega = .96-.98) and test-retest reliability (r = .78-.87, n = 29). A significant difference was observed between the lymphedema group and non-lymphedema group (p < .001) in terms of total scale, symptom occurrence (p < .001), symptom distress in the physical-functional (p < .001), and psychosocial dimension (p < .001). Principal component analysis for symptom occurrence revealed a unidimensional factor and two factors were identified for symptom distress via exploratory factor analysis, the two of which explained 45.71% and 54.77% of the total sample variance, respectively. CONCLUSIONS: This study provided initial evidence to support the psychometric properties of the BCLE-SEI Spanish version.
