The Bergen–Social Media Addiction Scale (BSMAS): longitudinal measurement invariance across a two-year interval

ABSTRACT Objective This study aims to examine the longitudinal measurement invariance of the Bergen Social Media Addiction Scale (BSMAS) over a two-year interval, addressing a gap in research on its consistency over time. Method Confirmatory Factor Analysis with a robust maximum likelihood chi-square estimator was utilised to assess the BSMAS among 276 adults (mean age = 31.86 years; SD = 9.94 years; 71% male) at three time points across two years. This method evaluates the scale’s structural consistency and reliability longitudinally. Results The analysis supported full measurement invariance (configural, metric, scalar, and error variance) of the BSMAS, indicating stable measurement properties over time. Furthermore, temporal stability and equivalency of the BSMAS total mean scores were confirmed across the three-time points, suggesting consistent measurement of social media addiction. Conclusions The findings validate the BSMAS as a reliable instrument for measuring social media addiction over extended periods. Demonstrating its psychometric stability enhances its utility for longitudinal studies, making it a valuable tool for tracking changes in social media addiction behaviours. These results have significant implications for future research and clinical practice, highlighting the BSMAS’s applicability in long-term studies.

A Quantitative Study Examining the Relationship Between Parental Socioeconomic Status, Body Image, Peer Influence, and Self-esteem Among Adolescents

People with high self-esteem are better able to take delight in life's little pleasures, handle difficult situations, overcome challenges, establish lasting relationships, and strengthen their weaknesses. This study examined socioeconomic status, body image, and peer influence on self-esteem among in-school adolescents in Ibadan, Nigeria. The descriptive survey design of the correlational type was used during the investigation. This study employed a multi-stage sampling technique. Three hundred and forty-five in-school adolescents made the study sample. Data was collected using reliable instruments: (Peer Influence Scale α = .78; Body image scale α =0.83; Parental Socioeconomic Status Scale α =0.89; Self-Esteem Inventory α=.71). From the results, socioeconomic status (r = .533; p.<05), body image (r =. 577; p.<05), and peer influence (r = .331; p.<05) had a significant relationship with (self-esteem). Body Image made the most significant contribution (β = .371; t = 7.555; p<0.05) followed by Peer influence (β = .316; t = 8.112; p<0.05) and Socioeconomic status (β = .312; t = 6.374; p<0.05). The study underscores the need for counseling and orientation programs for adolescents in all ramifications; this will help ease the psychological strain that could hamper their self-esteem.

Pilot Testing Transcreated Spanish-Language Study Materials for Symptom Research With Infants and Parents in the Neonatal Intensive Care Unit.

Rising admission rates of Hispanic/Latinx families to the neonatal intensive care unit (NICU) have increased the number of non-English-speaking individuals who may wish to participate in research studies. However, a lack of appropriately translated research study materials may limit the opportunity for these families to be involved in research that could impact the care that infants and families receive in the NICU. The primary purpose was to pilot test study materials that were transcreated from English to Spanish with the assistance of a bilingual community advisory board with Spanish-speaking parents of NICU infants. A total of 19 Spanish-speaking parents (15 mothers and 4 fathers) who were representative of the population of interest completed paper-and-pencil surveys, along with a cognitive interview. Preliminary data related to decision-making and goals of care, infant symptoms, and their experiences in the NICU were also collected. The internal reliability of the transcreated study instruments ranged from good to excellent (α= 0.82-0.99). Participants reported that study materials were not offensive and did not make them feel uncomfortable; however, they found some words/phrases to be confusing. Parents had the opportunity to provide suggested wording changes. Language barriers and a lack of cultural responsiveness can affect the care that infants and their families receive. More accurate and culturally appropriate transcreation of study materials can remove barriers to research participation and facilitate better communication with non-English-speaking families, which may lead to the development of better-informed evidence-based interventions and clinical practices in the NICU.

Evaluating the factor structure, reliability and validity of the Copenhagen Burnout Inventory-Student Survey (CBI-SS) among faculty of arts students of Ekiti State University, Ado-Ekiti, Nigeria

The Copenhagen burnout inventory-student survey (CBI-SS) has shown promising psychometric properties in diverse student populations. This study aims to investigate the psychometric properties of the Nigerian version of the CBI-SS. This was a cross-sectional study of 635 students from Ekiti State University, Ado-Ekiti, Nigeria. Confirmatory factor analysis (CFA) was utilized to assess the CBI-SS validity. The reliability score of the CBI-SS was 0.957, ranging from 0.862 to 0.914 for the subscales. Correlation coefficients among the four CBI-SS factors ranged from 0.507 to 0.713. The CFA indicated an adequate goodness-of-fit for the four-factor model of the CBI-SS with the sample data. However, Item 10 was removed due to unacceptably low Average Variance Extracted score. The four factors demonstrated a negative correlation with both General Academic Self-Efficacy Scale and Cumulative Grade Point Average. Furthermore, both self-reported burnout and perceived course stress showed associations with the CBI-SS, where lower levels of burnout corresponded with lower median scores on the CBI-SS scales. This study underscores the significance of the CBI-SS in evaluating student burnout within our student population. The findings indicate that the CBI-SS is a highly reliable and valid instrument for assessing student burnout, suggesting its potential for effective utilization in the Nigerian academic context.

The Chinese version of the general benefit finding scale (GBFS): Psychometric properties in a sample of college students.

Benefit finding has become a central construct in the evolution of positive psychology and attracted attention in recent literature. This study aimed to translate and validate the General Benefit Finding Scale (GBFS) in Chinese college students. Forward- and back-translation of the GBFS was followed by the assessment of semantic equivalence and content validity. A sample of 589 college students was recruited in China to conduct reliability and validity analysis. The construct validity was assessed using exploratory (EFA) and confirmatory factor analysis (CFA). Concurrent validity was assessed using Pearson's correlation coefficients of the GBFS with the Perceived Stress Scale (PSS) and World Health Organization-Five Well-Being (WHO-5). Internal consistency and two-week test-retest reliability were also evaluated. The content validity index for each item ranged from 0.83 to 1.00. EFA revealed a six-factor model, which exhibited acceptable goodness of fit in CFA (standardized root mean square residual = 0.031, root mean square error of approximation = 0.059, goodness-of-fit index = 0.860, comparative fit index = 0.904, Tucker-Lewis index = 0.890, chi-squared/degree of freedom = 2.07). The concurrent validity of the GBFS was supported by its statistically significant correlations with PSS (r = -0.271, p<0.001) and WHO-5 (r = 0.354, p<0.001). Moreover, the internal consistency for the overall scale was satisfactory, with Cronbach's α coefficient of 0.93 and McDonald's omega reliability of 0.94. The test-retest reliability was 0.82. Although the Chinese version of GBFS was examined in a homogeneous convenience sample of college students, it provides a reliable and valid instrument for assessing benefit finding in the Chinese context.

The athlete psychological well-being inventory: Factor equivalence with the sport injury-related growth inventory

Until now, research on growth following sport injury has relied exclusively on retrospective reports and nomothetic measures drawn from other fields of research. Therefore, to more objectively explore growth following sport injury pre- and post-injury, rather than retrospectively, this study adapts and examines the psychometric properties of the Athlete Psychological Well-Being Inventory (APWBI), which can be used throughout the sport injury process (i.e., prior to and following sport injury). A sample of 164 athletes free from injury (71.3 % men; M age = 19.7 years, SD = 2.1) were compared to a sample of 168 athletes with history of previous injury (73.2 % men; M age = 19.7 years, SD = 2.1). Multigroup Confirmatory Factor Analysis demonstrated the measurement and factor equivalence between the APWBI and a retrospective measure, the Sport Injury-Related Growth Inventory (SIRGI). The APWBI also showed satisfactory to excellent internal consistency reliability for all its sub-dimensions (“sense of mastery”, “positive relations with others”, “responsibility for one’s health”, “self-awareness”, “emotional ability”, “purpose in life”, “purpose in sport”, and “body awareness”) and for the total score. Analysis of the relationships with other self-report measures (i.e., the Positive Functioning Inventory, the Rosenberg’s Self-Esteem Scale, and the Lie Scale) provided convergent and discriminant evidence to support the construct validity of the instrument. To conclude, the APWBI is a valid and reliable instrument for use within English-speaking athletes of various competitive levels (from local/county to international level).

Conceptualization and measurement of foreign language playfulness via exploratory structural equation modeling

The current research sought to conceptualize and measure foreign language playfulness (FLP), a recently developed construct in second language acquisition (SLA), through exploratory structural equation modeling (ESEM), a recently introduced scale measurement approach. Using a sample of 208 Iranian undergraduate language learners, we employed a series of statistical techniques to examine the underlying structure, best fitting model, psychometric properties, measurement invariance, and factor correlation of a new measure of FLP. Findings showed that bifactor EFA, compared with EFA, provided better representation for the underlying structure of the FLPS. Multiple model comparisons indicated that the bifactor ESEM model had a more satisfying representation of the FLPS than the other models (CFA, bifactor CFA, and ESEM). Cronbach's α and omega (ω) demonstrated that the FLPS is a reliable instrument. The bifactor ESEM model of the FLPS was also invariant across genders. Finally, factor correlation in ESEM exhibited a more accurate reflection of the association between the two factors (intellectual playfulness and other-directed playfulness) of the FLPS. The results were discussed by highlighting the importance of using ESEM to validate psychological constructs in SLA.

Gender Differences in Anthropometric, Functional Capacity Measures and Quality of Life in Individuals with Intellectual and Developmental Disabilities.

The aim of the of the current investigation was to investigate the possible differences concerning males and females in anthropometry, body composition, functional capacity, strength and quality of life variables. After obtaining signed informed consent, 37 participants (18 males; 19 females), with mean age of 39.08 and standard deviation of 11.66 years, voluntarily participated in this study. Anthropometry, body composition, functional capacity, strength, and quality of life were assessed using validated and reliable instruments and tests for this population. The males and females were compared using a Mann-Whitney U signed rank test. Significant differences were detected among the following variables, height (p = 0.028), body mass index (p = 0.033), fat mass (p = 0.002), muscle mass (p ≤ 0.001), phase angle (p = 0.005), medicine ball throwing strength (p = 0.010), and peak toque left knee (p = 0.028), with males showing better results in all the variables. The sample in this study showed differences in the anthropometric, composition, and strength variables. Studying this population can help ensure that everyone has equal access to services and adequate support for their personal needs, improving their quality of life.

Evaluation of the Oral Hygiene Ability Instrument (OHAI): Test of reliability.

To evaluate the reliability of the new Oral Hygiene Ability Instrument (OHAI) developed to assess the cause of any inability for older adults to manage oral hygiene self-care. Oral hygiene is an important part of oral health. The inability to manage oral hygiene, combined with other risk factors, often results in poor oral health and impaired quality of life. A reliable OHAI could benefit preventive oral health care. The preliminary OHAI uses 33 items in three parts: (I) interview, (II) clinical examination and (III) observation of oral hygiene activities. A total of 37 older adults participated in a test-retest study of Part I. Inclusion criteria were age ≥ 65 years, have at least one tooth and be able to oral hygiene self-care. The intra- and inter-rater reliability of parts II and III used films and photographs of OHAI assessments of 15 different individuals. These films/photographs were assessed twice by four dental professionals who had participated in the OHAI data collection. For statistical analyses of the reliability, per cent agreement, Krippendorff's alpha and E. Svensson's method were used. The test-retest for Part I items showed acceptable-to-good agreement and no systematic disagreement. In Part II, two items showed somewhat limited reliability. Part III showed good intra- and inter-rater reliability. The OHAI items seem stable and reliable for the intended sample, and the instrument may be a valuable tool to identify older adults at risk of impaired oral health. However, two items may need to be reformulated.

Business Management as a Link Between Competitiveness and Sustainable Development in the Textile Sector

Efficient resource management plays a crucial role in the sustainable development of companies, aiming to maximize economic performance, minimize environmental impacts, and contribute to social welfare. This quantitative and explanatory study analyzed resource management in textile microenterprises in Metropolitan Lima, with a sample of 370 participants. The methodology used was non-experimental and cross-sectional, allowing for a detailed analysis of the relationship between business management and sustainable development in this specific context. Two questionnaires of 20 questions each were administered. Both instruments were validated by five experts in the business area. The Aiken's V for the first instrument was 0.83 and for the second instrument was 0.79. Additionally, a pilot test was conducted for instrument reliability, obtaining 0.89 for the first instrument and 0.81 for the second. The results highlight the significant relationship between business management and sustainable development, especially in terms of competitiveness and general management aspects. However, there is a relatively lesser association of eco-efficiency, eco-effectiveness, and continuous improvement in the variability of sustainable development. It is concluded that, while business management is considerably related to sustainable development, aspects such as eco-efficiency and continuous improvement show a less pronounced relationship in sustainable development variability. These findings underscore the importance of sustainability-focused business management to enhance competitiveness and foster equitable and long-term sustainable development.

Purpose This study aimed to translate, cross-culturally adapt, and validate the MedRisk Instrument for Measuring Patient Satisfaction with Physical Therapy Care into Arabic (MRPS-Ar). Materials and Methods The 20-Item MRPS was translated and cross-culturally adapted into Arabic following international guidelines. Patients (n = 229) with musculoskeletal conditions who received physical therapy care completed the MRPS-Ar and global rating of change scale. Of these patients, 95 completed the MRPS-Ar twice. Factor structure, floor and ceiling effects, internal consistency, test-retest reliability, and construct validity of the MRPS-Ar were evaluated. Results Principal component analysis suggested 3-factor solution: a 7-item facility experience, 6-item therapeutic experience, and 3-item positive experience. The MRPS-Ar and its factors showed acceptable internal consistency (Cronbach’s alpha coefficients ranged from 0.819 to 0.936) and excellent test-retest reliability (ICCs ranged from 0.965 to 0.983). The global measures of satisfaction were significantly correlated with the global rating of change (Spearman’s rho = −0.678, p < 0.001 for item “overall satisfaction” and Spearman’s rho = −0.690, p < 0.001 for item “would return”). Conclusions The 18-item MRPS-Ar displayed adequate psychometric properties for measuring patients’ satisfaction with physical therapy care.

Hospital Environmental Factors That Influence Peripheral Oxygen Saturation Measurements: A Cross-Sectional Study.

Pulse oximetry is a non-invasive, cost-effective, and generally reliable instrument measuring pulse rate and peripheral oxygen saturation (SpO2). However, these measurements can be affected by the patient's internal or external factors, including the type of pulse oximeter device (POD). (1) This study's objective was to identify potential environmental factors that may impact the measurements taken by three PODs. (2) Methods: A descriptive-analytical cross-sectional study was designed. The patients' SpO2 levels were measured using a standard monitor and two PODs owned by the professionals. The measurements were taken on the patients' fingers. Concurrently, we evaluated the surrounding environmental conditions, encompassing temperature, humidity, illuminance, and noise. (3) Results: This study involved 288 adult participants in the sample. For each 20-decibel increment in noise, there was a reduction in SpO2 by an average of 1%, whereas for every additional degree of ambient temperature, SpO2 decreased by an average of 2% (4) Conclusions: Significant correlations between SpO2 and age, as well as with noise and ambient temperature, were observed. No significant differences between oxygen saturation and lighting or humidity were observed. This study was prospectively registered with the Clinical Research Ethics Committee of Gran Canaria at the Dr. Negrín University Hospital, with protocol code 2019-247-1, and approved on 24 May 2019.

Development and initial validation of a disease-specific instrument to measure health-related quality of life in hypersensitivity pneumonitis

Rationale and ObjectiveDisease-specific health-related quality of life (HRQOL) instruments enable us to capture domains that are most relevant to specific patient populations and are useful when a more individualized approach to patient assessment is desired. In this study, we assessed the validity and reliability of the first instrument specifically developed to measure HRQOL in Hypersensitivity Pneumonitis (HP).MethodsA 39-item HP-HRQOL instrument and several anchors were collected from a cohort of patients with HP. Exploratory factor analysis and item reduction were utilized to construct a shortened version of the instrument. Several validity and reliability analyses were conducted on this version of the HP-HRQOL.Measurements and Main Results59 patients with HP completed the study. The revised HP-HRQOL instrument comprises 15 items composing 2 factors (domains): 1. Impacts on daily life; 2. Mental well-being. Internal consistency reliability was strong for factor 1 (Cronbach's alpha=0.94, 95% CI {0.92–0.96}) and factor 2 (Cronbach's alpha= 0.89, 95% CI {0.85–0.94}). Test re-test reliability was strong (ICC 0.94 95% CI {0.89–0.97}). The HP-HRQOL strongly correlated with other validated patient reported outcome measures and moderately correlated with %predicted forced vital capacity. The HP-HRQOL distinguished between those with different severities of HP as determined by lung function and supplemental oxygen use.ConclusionsThe HP-HRQOL, the first patient reported outcome instrument specific to adults with HP, possesses strong validity and reliability characteristics for measuring disease-specific HRQOL and distinguishes among patients with different severities of disease.

OpenCell: A low-cost, open-source, 3-in-1 device for DNA extraction.

High-cost DNA extraction procedures pose significant challenges for budget-constrained laboratories. To address this, we introduce OpenCell, an economical, open-source, 3-in-1 laboratory device that combines the functionalities of a bead homogenizer, a microcentrifuge, and a vortex mixer. OpenCell utilizes modular attachments that magnetically connect to a central rotating brushless motor. This motor couples to an epicyclic gearing mechanism, enabling efficient bead homogenization, vortex mixing, and centrifugation within one compact unit. OpenCell's design incorporates multiple redundant safety features, ensuring both the device's and operator's safety. Additional features such as RPM measurement, programmable timers, battery operation, and optional speed control make OpenCell a reliable and reproducible laboratory instrument. In our study, OpenCell successfully isolated DNA from Spinacia oleracea (spinach), with an average yield of 2.3 μg and an A260/A280 ratio of 1.77, demonstrating its effectiveness for downstream applications such as Polymerase Chain Reaction (PCR) amplification. With its compact size (20 cm x 28 cm x 6.7 cm) and lightweight design (0.8 kg), comparable to the size and weight of a laptop, OpenCell is portable, making it an attractive component of a 'lab-in-a-backpack' for resource-constrained environments in low-and-middle-income countries and synthetic biology in remote field stations. Leveraging the accessibility of 3D printing and off-the-shelf components, OpenCell can be manufactured and assembled at a low unit cost of less than $50, providing an affordable alternative to expensive laboratory equipment costing over $4000. OpenCell aims to overcome the barriers to entry in synthetic biology research and contribute to the growing collection of frugal and open hardware.

Validation and Measurement Invariance of the German and Spanish Gender Bias Scale for Women Leaders

AbstractGender bias still appears to contribute significantly to the gender disparity observed in upper leadership positions. The present study presents the translation, modification, and validation of the Gender Bias Scale for Women Leaders (GBSWL, Diehl et al., 2020) into German and Spanish. Using data from four samples of full-time employed women from Germany and Spain with and without leadership responsibility (N = 870), we conducted confirmatory factor analyses to establish factorial validity, tested measurement invariance across the different job levels and countries, and tested construct validity. Our results indicate that the original factor structure does not hold in Germany and Spain. Therefore, utilizing the German leader sample as a construction sample, we modified the factor structure and validated the modified version using the remaining three samples. The modified version demonstrated good model fit, had metric measurement invariance across all samples, and resulted in a correlational pattern consistent with theory and the original study. Overall, results suggest that the German and Spanish versions of the GBSWL are reliable and valid instruments that scholars and practitioners can use to advance theory, research, and human resource practice in Germany and Spain.

Abstract PO2-25-09: The hidden costs of beauty: An evaluation of breast cancer risk for Black women

Abstract The Black identity, hair product use, and breast cancer scale (BHBS) was developed and previously validated to evaluate the relationship between identity, hair product use, and breast cancer risk for Black women. Black women are disproportionately affected by breast cancer compared to other racial/ethnic groups, with a mortality rate of 40% higher than all other groups. Endocrine Disrupting Chemicals (EDCs) are present in many hair care products and have been linked to several health issues including breast cancer. Due to these health inequities and the complexity of how cultural norms shape Black women’s hair product usage, the purpose of this study was to assess the reliability of the BHBS for intervention planning and evaluate the hazard scores of hair products used by Black women. Methods: Participants were recruited using purposive convenience sampling techniques. The 11-item BHBS includes two subscales: five items measuring sociocultural perspectives about hair and identity (S1) and six items assessing perceived breast cancer risk related to hair product use (S2). To determine reliability, the BHBS was administered twice over a three-week period with sociodemographic factors obtained in the initial data collection phase. All statistical analyses, including descriptive statistics and test-retest reliability (Pearson correlations) were conducted using SPSS version 26. The Environmental Working Group's (EWG's) Skin Deep® database was used to determine hazard scores of hair products used by participants. Products are rated on a 10-point scale with low (0-2), moderate (3-6), and high hazard (7-10) scores. Results: Twenty-three (86.9% African, African American &amp; Caribbean; 13% multiracial) female participants completed the study. Their age ranged from 18-63 years (30.78, SD= 15.40), 47.8% reported an income of less than $25,000, and 34.8% completed some college education. Both subscales demonstrated highly significant and strong reliability (S1: r=.82, p&amp;lt; .001; S2: r=.88, p&amp;lt; .001). Participants primarily used conditioners (91.3% used wash out and 60.9% used leave-in), and professional hair dyes (34.8%). There was also a high frequency of non-use (91.3%) of do-it-yourself relaxers and hair dye kits. We evaluated 40 products across three categories including wash out conditioners, leave-in conditioners and other hair products (e.g., styling gels, shampoo, and hair oils), of which most had a moderate hazard rating of 5 denoting ingredients of health concerns (e.g., parabens, fragrance, and phenoxyethanol). Additionally, of the 22 company brands analyzed, only 10 (45%) are Black owned or founded. Conclusions: The BHBS is a valid and reliable instrument to assess sociocultural perspectives about hair, identity and perceived breast cancer risk. Black women use hair products including relaxers, hair dyes, and conditioners that contain EDCs that may be harmful to their health including risk for breast cancer. The BHBS will be used to evaluate psychosocial interventions that address the unique needs of Black women including exposure to EDCs from hair product use and breast cancer risk.
