Longitudinal effects of sexual minority stigma on depressive symptoms among young men who have sex with men: Distinguish between and within person effects.

Young men who have sex with men (YMSM) may experience high levels of sexual minority stigma (SMS) and depressive symptoms (DS) over the world and in China. However, there is a lack of studies investigating the longitudinal effects of SMS on DS of YMSM, especially focusing on YMSM and separating the between-person and within-person effects. This study aimed to fill the said gaps. Study data were derived from a prospective cohort of 349 YMSM from central China (Wuhan, Changsha, Nanchang), the baseline survey was started in 2017 with one follow-up visit every year. SMS and DS were measured three times using valid and reliable instruments. The cross-lagged panel model (CLPM) and the random intercept CLPM (RI-CLPM) were used to examine the between-person and within-person concurrent and lagged effects, respectively. Findings of CLPM revealed bidirectional associations between SMS and DS over time. RI-CLPM suggested that at the between-person level, SMS was significantly associated with DS, echoing the results of CLPM. However, this reciprocal relationship has not been found at the within-person level. The associations between SMS and DS among YMSM at the population level is more significant than that at the individual level. We suggest that interventions should be against the adverse effects of cultural marginalization and systemic change the social concepts to reduce the amount of SMS in society.

Impact of Compensation Strategies on Employees Satisfaction Case Study in the A. S. XYZ Organization

Purpose: The objective of this study is to investigate the impact of compensation on employee loyalty and performance, through job satisfaction as mediator at A. S. XYZ. Methodology: The research population comprised all the employees of A. S. XYZ. Simple random sampling, which is a probability sampling method, was adopted to include members of the population at random, leading to a total sample size of 327 people. Data analysis derived from the results of questionnaire responses in Google Forms and data extracted from A. S. XYZ was conducted. The questions were tested using Cronbach’s alpha and face validity tests in order to assess the reliability and validity of the research instrument. Findings: The findings indicated that compensation and job satisfaction had a positive and direct effect on employee loyalty and performance. Also, the study revealed that job satisfaction serves as a partial mediator between compensation and employee loyalty and performance, implying that compensation can influence employee loyalty and performance directly or indirectly through the mediating capacity of job satisfaction. Unique Contribution to Theory, Practice and Policy: This research adds to the body of literature by affirming the theoretical implications of prior research and providing recommendations for A. S. XYZ to improve its compensation methods and meet employees’ needs. The findings stress on the fact that the payment systems should be constantly monitored and adjusted in the context of other factors influencing employee satisfaction like career development and work environment as well. This research highlights the importance of open communication between supervisors and workers that help in recognizing and resolving the problems quickly. Further, the research suggests that organizations should apply a holistic method of employee satisfaction rather than depending only on compensation matters. The outcomes of this research are relevant for theory, practice, and policy. Theoretically, the research supports and develops the current frameworks on the link between compensation, job satisfaction, employee loyalty, and performance. In practical terms, the research gives implementable recommendations for A. S. XYZ and other organizations to align their compensation policies and create a content, loyal and productive workforce. Policy wise, the study emphasizes the importance of organizations developing holistic employee satisfaction policies that extend beyond financial rewards to encompass additional aspects such as career development and work environment. Additional research could study other variables that contribute to employee satisfaction and recommend techniques on how to sustain high levels of satisfaction for extended periods using a mixed method approach. An alternative methodology entails both qualitative and quantitative methods.

Validity and reliability of the Persian version of food preferences questionnaire (Persian-FPQ) in Iranian adolescents

The assessment of dietary intakes and habits using reliable and youth-specific measurement tools during adolescence is essential. The aim of the present study was to culturally adapt and investigate the psychometric properties of the Persian version of the food preferences questionnaire (Persian-FPQ) among Iranian adolescents. This methodological cross-sectional study was conducted among 452 Persian-speaking adolescents, living in Isfahan, Iran. Translation of the FPQ was performed using forward–backward method. Intra Class Correlation (ICC) and Cronbach’s α were used to assess test–retest reliability and internal consistency, respectively. Construct validity was investigated by using exploratory factor analysis (EFA). Divergent validity was determined using correlation analysis with Kessler Psychological Distress Scale (K-10). Known-group validity was assessed based on differences in mean food preference score between boys and girls and different categories of body mass index (BMI). The internal and external reliabilities for the Persian-FPQ were in the range of good to excellent in all domains (Cronbach’s α: 0.76–0.96 and ICCs: 0.982–0.998). Boys had higher scores of food preferences than girls, indicating good known-group validity. Construct validity evaluated by EFA led to extraction of seven factors (“Vegetables”, “Fruit”, “Dairy”, “Snacks”, “Meat/Fish”, “Starches” and “Miscellaneous foods”), explaining 37.8% of the variance. Divergent validity revealed significant negative correlations between five sub-scales of the Persian-FPQ and psychological distress. The Persian version of the FPQ is a reliable and valid instrument with applicability in a broad range of the population of Persian-speaking adolescents for assessing food preferences in community-based research projects.

Experiences of experts in intelligence measurement of South African school learners

This qualitative research study emerged from the essential need for reliable and valid intelligence test instruments for South African school learners, who are characterised as a diverse population with their variety in culture, ethnicity, and language, as well as having unequal socio-economic and educational backgrounds. The aim of this research study was to use a qualitative interpretive description research design to explore and describe the experiences of both experts in intelligence test development and/or adaptation as well as psychologists and psychometrists who have administered intelligence tests to South African school learners in various contexts. Twelve psychologists and/or psychometrists were interviewed, of which six were also experts in test development and/or adaptation, which yielded four themes after thematic analysis, namely, utilised intelligence measurements in the current South African school learner context are less relevant; the South African education system is a major issue specifically within lower socio-economic status (SES) contexts; it does not seem feasible to design or adapt suitable intelligence measures that are valid and reliable in the current South African school learner context; and key informants’ recommendations from their experiences.Contribution: This research study contributes to the understanding of the measurement of intelligence of South African school learners in diverse contexts. Findings of this research study can guide the strategic process to design an intelligence instrument suitable for a South African population of school learners, informing fair assessment practices for multiethnic equalisation.

Measuring Shame Related to Sexual Orientation: Validation of Sexual Minority—External and Internal Shame Scale (SM-EISS)

Abstract Introduction Shame is a self-conscious emotion involving negative self-evaluations, being a transdiagnostic factor for psychopathology. Due to stigma and discrimination experiences related to having a minority sexual orientation, LGB+ (lesbian, gay, bisexual, and other minority sexual orientations) people report higher levels of general shame than heterosexual people. To our knowledge, there is no specific measure of shame related to sexual orientation. This study aimed to develop and explore the psychometric properties of the Sexual Minority—External and Internal Shame Scale (SM-EISS) in a sample of Portuguese LGB+ people. Method The sample was recruited online between December 2021 and January 2022 and comprised 200 Portuguese LGB+ people (Mage = 27.8 ± 8.9) who completed measures about shame, proximal minority stressors, and mental health. Results Good psychometric characteristics were found for a second-order two-factor structure (general, external, and internal shame related to sexual orientation), with the SM-EISS demonstrating good reliability and validity values. Conclusion The SM-EISS seems to be a valid and reliable instrument to assess shame related to sexual orientation among LGB+ people and may be beneficial in clinical and research contexts. Policy Implications Measuring shame related to sexual orientation experienced by LGB+ people could enhance the clinical understanding of this population. It can help researchers and clinicians to better understand this emotion and how it affects LGB+ people’s mental health and well-being. The research has important implications for clinical practice, social interventions, and public policies to protect LGB+ people’s rights. This is especially relevant in Portugal, where, despite positive legal developments, LGB+ people continue to experience harmful situations that negatively impact their mental health.

Psychometric Properties of the Automated Insulin Delivery - Benefits and Burdens Scale (AID-BBS) for Adults with Type 1 Diabetes.

To evaluate the psychometric properties of a patient-reported outcome measure, The Automated Insulin Delivery - Benefits and Burdens Scale (AID-BBS), which was designed to assess benefits and burdens of AID use in adults with type 1 diabetes (T1D). The measure was hypothesized to have validity, reliability, and clinical utility for predicting likelihood of continued use of an AID system. 217 adults with T1D (ages 18 to 82 years) who were enrolled in an AID system research trial completed AID-BBS items at study midpoint (6 weeks) and at the end of the trial (13 weeks). Data were collected on pre-post glycemic outcomes. Participants completed other patient-reported psychosocial outcome measures (e.g., emotional well-being, diabetes distress, attitudes toward diabetes technology, diabetes treatment satisfaction) at Week 13. Likelihood of continued device use was assessed with three items at 13 weeks. Exploratory factor analysis supported a one-factor structure for each subscale (15-item benefit and 9-item burden subscale) when evaluated separately. Convergent, discriminant, and predictive validity, internal consistency, and test-retest reliability were supported. Benefit and burden subscales at week 6 predicted usage intention above and beyond device impact on glycemic outcomes, also controlling for baseline glycemic outcomes. Findings support the AID-BBS as a psychometrically valid, reliable, and useful instrument for assessing burdens and benefits associated with AID system use in adults with T1D. The measure can be used to help health care providers set realistic expectations and proactively address modifiable burdens.

Parental Perceptions of the Impact of a Child’s Complex Chronic Condition: A Validation Study of the Impact on Family Scale

The diagnosis of a child’s complex chronic illness may impact family relationships and cohesion. The Impact on Family Scale (IFS) is an instrument used to assess the parental perception of the effects of children’s chronic illness on family life. With a sample of 110 mothers and fathers between the ages of 29 and 50 who have a child with a complex chronic illness, we examine evidence of the validity of the IFS for use in Portugal within this specific family configuration, (1) comparing its factor structure with the original one; (2) assessing its reliability; and (3) evaluating its relationship with life satisfaction and family cohesion/acceptance. As expected, CFA analysis showed that IFS is a one-factor reliable instrument with 12 items (Cronbach’s alpha = 0.910), which are negatively correlated with satisfaction with life (r = −0.229, p = 0.016) and positively correlated with family acceptance and cohesion (r = 0.363; p < 0.001). The results support the validity of the IFS in families with children and adolescents with a complex chronic illness. The implications of the use of this instrument for research and professional practice is analyzed.

Validation of the Mediated Learning Observation Instrument Among Children With and Without Developmental Language Disorder in Dynamic Assessment.

In this validation study, we examined the factor structure of the mediated learning observation (MLO) used during the teaching phase of dynamic assessment. As an indicator of validity, we evaluated whether the MLO factor structure was consistent across children with and without developmental language disorder (DLD). Two hundred twenty-four children (188 typically developing and 36 DLD) from kindergarten to second grade completed a 30-min individual mediated learning session on narrative production. Performance during the session was rated using the 12-item MLO by clinicians on affect, behavior, arousal, and elaboration. Exploratory and confirmatory factor analyses were conducted to establish the factor structure and reliability of the MLO. Factor analysis of the MLO suggested a stable three-factor model with adequate fit indices across kindergarten and school-age samples, across both typically developing and DLD subgroups with good to excellent reliability. The final 11-item MLO (one item was removed due to low factor loading) comprises three subscales including (a) cognitive factor, (b) learning anticipation, and (c) learning engagement. The MLO is a valid and reliable instrument for assessing language learning skills in children with and without DLD during dynamic assessment. Practical implications and suggestions for future research addressing the utilization of MLO in dynamic assessment are provided.

Development of a distance education attitude scale for lifelong learning (DEAS-LLL): a validity and reliability study

ABSTRACT In recent times, the utilization of distance education (DE) has witnessed a notable surge across various sectors, particularly amidst the backdrop of pandemics. This study aimed to develop a comprehensive Distance Education Attitude Scale tailored for Lifelong Learning (LLL) contexts. Methodologically, the research enlisted the participation of 260 physicians, employing a five-point Likert scale design. The content validity index yielded an impressive score of 0.92. Following a rigorous 48-item pilot application among 30 physicians, a refined 37-item draft scale emerged. Through explanatory factor analysis, the scale revealed a robust 4-factor structure comprising 22 items. Model fit indices, gauged through confirmatory factor analysis, underscored the scale's coherence and alignment. In the test-retest phase, an analysis utilizing Pearson Correlation Coefficient yielded a robust correlation coefficient of r = 0.891, signifying high stability over time. Moreover, a paired-sample t-test revealed non-significant differences (t = −0.041, p:0.968), further affirming the scale's reliability. With a commendable Cronbach's alpha value of 0.946, the finalized “Distance Education Attitude Scale in Lifelong Learning” stands as a validated and highly reliable instrument, particularly among physicians. Its applicability extends to academic inquiries regarding distance education and holds promise for validation across diverse adult learning cohorts.

Translation and psychometric validation of the Chinese version of the metacognitive awareness scale among nursing students

ObjectiveThis study endeavors to translate and psycho-metrically validate the metacognitive awareness inventory scale (MAS) for nursing students in China.MethodA total of 592 nursing students were enlisted from four universities situated in the eastern, southern, western, and northern regions of China. Content validity and reliability were evaluated using the content validity index and item-total correlation coefficient, and Cronbach’s alpha coefficients, respectively. Convergent validity examined the goodness of fit among sub-scales through the average extracted variance and composite reliability.ResultsExploratory factor analysis confirmed the first-order and second-order factor models, contributing to a cumulative variance of 89.4 and 59.5%, respectively. The Cronbach’s alpha values were 0.963 and 0.801, respectively. Confirmatory factor analysis outcomes indicated an excellent overall fit index for the model, satisfying the convergent validity criteria and achieving a target coefficient of 96.0%, which is consistent with the original scale structure.ConclusionThe Chinese version of the MAS (C-MAS) is a reliable and valid instrument for assessing metacognitive awareness among Chinese nursing students. Further research should consider a broader sample of nursing students across China to reinforce the scale’s applicability.

Validation of the Mexican version of the EORTC QLQ-CR29 in patients with colorectal cancer.

The evaluation of the quality of life (QoL) of patients with colorectal cancer (CRC) is an essential measure to measure the impact of the disease and treatments on the lives of patients. However, in Latin America there is no validated and reliable instrument to assess this construct. This study aims to validate the EORTC QLQ-CR29 instrument in the Mexican population with CRC. This study aims to validate the EORTC QLQ-CR29 instrument in the Mexican population with CRC. The study used an instrumental design and a nonprobabilistic sample due to availability, made up of 251 patients with CRC, with an average age of 54.7 ± 12.28 years. Exploratory and confirmatory factor analyses were performed, as well as concurrent validity tests. The exploratory factorial analysis yielded 4 factors that explained 51.64% of the variance, with a Cronbach reliability coefficient of .766 and an Omega index of .725. The confirmatory factor analysis indicated that the proposed theoretical model fits the data almost perfectly, with an error close to 0, which shows that it is a balanced and parsimonious instrument to measure the QoL of the patients with CRC. The EORTC QLQ-CR29 instrument proved to be a valid and reliable instrument for use in clinical care and research directed at patients with CRC in Mexico. Its use is recommended by multidisciplinary health teams in oncology in Mexico, since it allows knowing the patient's perspective on the impact of CRC on their life, guiding therapeutic decision-making and being a primary outcome measure.

Measuring psychotherapeutic processes in the context of psychedelic experiences: Validation of the General Change Mechanisms Questionnaire (GCMQ).

Therapeutic and salutogenic effects of psychedelic drugs have been attributed to psychotherapeutic or psychotherapy-like processes that can unfold during the acute psychedelic experience and beyond. Currently, there are no psychometric instruments available to comprehensively assess psychotherapeutic processes (as conceptualized by empirical psychotherapy research) in the context of psychedelic experiences. We report the initial validation of the General Change Mechanisms Questionnaire (GCMQ), a self-report instrument designed to measure five empirically established general change mechanisms (GCMs) of psychotherapy-(1) resource activation, (2) therapeutic relationship, (3) problem actuation, (4) clarification, and (5) mastery-in the context of psychedelic experiences. An online survey in a sample of 1153 English-speaking and 714 German-speaking psychedelic users was conducted to evaluate simultaneously developed English- and German-language versions of the GCMQ. The theory-based factor structure was confirmed. The five GCMQ scales showed good internal consistency. Evidence for convergent validity with external measures was obtained. Significant associations with different settings and with therapeutic, hedonic, and escapist use motives confirmed the hypothesized context dependence of GCM-related psychedelic experiences. Indicating potential therapeutic effects, the association between cumulative stressful life events and well-being was significantly moderated by resource activation, clarification, and mastery. Factor mixture modeling revealed five distinct profiles of GCM-related psychedelic experiences. Initial testing indicates that the GCMQ is a valid and reliable instrument that can be used in future clinical and nonclinical psychedelic research. The five identified profiles of GCM-related experiences may be relevant to clinical uses of psychedelics and psychedelic harm reduction.

Development and Validation of a Comprehensive Nursing Competence Assessment Questionnaire (CNCAQ) to Determine the Perceived Clinical Competence of Nursing Graduates

Background: An assessment of the clinical competency of nurses at the time of their graduation is essential to get a fair estimate of their level of competence. It helps to lessen the burden on the healthcare system. A “Comprehensive Nursing Competence Assessment Questionnaire (CNCAQ)” has been constructed to fulfil this purpose. Aim: This study aims to develop and validate a CNCAQ to determine the perceived clinical competence of final-year nursing graduates who are about to graduate within three months from selected private and government nursing colleges in India. Methods: A mixed methodology was used and completed in two phases. In phase 1, along with an extensive literature review, focus group discussions, expert evaluation, and pretesting were done, in which 10 nursing experts participated. In phase 2, data were collected from 649 nursing graduates to establish the validity of the construct. The study period was from August to October 2022. Results: The developed CNCAQ has 36 items, comprising four sections: (a) conceptual knowledge and skill in routine nursing care; (b) skill in basic nursing procedures; (c) skill in advanced nursing procedures; and (d) assessment of infusion/transfusion-related nursing procedures. The overall reliability of the tool was 0.963, indicating its high reliability. Overall, there was no difference in clinical competency skills between female and male upcoming nursing graduates. However, statistically significant differences in basic nursing skills and advanced and analytical nursing skills were observed. Conclusions: Assessing nursing students’ competencies is crucial to ensure that they possess the necessary knowledge, skills, and attitudes to provide safe and effective patient care. The development and validation of a valid and reliable instrument for assessing nursing competencies are essential to evaluate nursing students’ clinical performance accurately. In the present research, a tool with a total of 36 items was used. It demonstrates high reliability; however, it needs to be applied to a larger population of nursing graduates with diverse backgrounds. Nurse educators and administrators can use it to assess the level of competence and, accordingly, a tailor-made induction program based on identified weak areas in theoretical and practical knowledge or skill can be developed. No patient’s were involved in the study. It involved developing a CNCAQ and validating it on a selected group of upcoming nursing graduates.

Measurement of sustainable attitudes: a scale for business students

Purpose This study aims to present the development and validation of a scale to measure the attitudes of Latin American business students toward sustainable management practices in the economic, social and environmental dimensions. Design/methodology/approach Using a nonprobabilistic sample, the appreciation for sustainable practices in students (ASP-S) scale was administered to a total of 653 undergraduate and graduate business students in Argentina, Colombia, Mexico and Peru. A range of psychometric validity (construct, convergent and discriminant) and reliability criteria were applied. Findings Construct, convergent and discriminant validity was obtained from the ASP-S scale across all samples. During the internal validation process, two factors were found: systemic consciousness (ten items) and sustainable business leadership (nine items), both of which obtained acceptable reliability indices. The resulting structure is equivalent in all four countries. Originality/value The instrument can be applied by educators and learning assurance areas to diagnose and measure the effectiveness of pedagogical strategies used in sustainability courses taught at Latin American business schools. As a result, it has applications for curriculum design. As a valid and reliable instrument set in the context of regional business praxis, it can promote an understanding of sustainable behaviors and practices in future Latin American leaders.

Validation of the Polish version of the Johns Hopkins Learning Environment Scale–a confirmatory factor analysis

The Johns Hopkins Learning Environment Scale (JHLES) was developed by Robert B. Shochet, Jorie M. Colbert and Scott M. Wright of the Johns hopkins university school of medicine and consists of 28 items used to evaluate perception of the academic environment. The objective was to translate and adapt the JHLES to Polish cultural conditions and to validate the Polish version of the tool. The JHLES questionnaire was completed by students of all years (first–fifth) of the faculties of dental medicine at the Medical University of Lublin and the Medical University of Gdańsk. The total surveyed population consisted of 597 students. The overall reliability of the tool was excellent. Confirmatory factor analysis was performed in order to confirm structural consistency with the original JHLES tool. Consequently, all indices had acceptable values (close to 1 or 0, depending on the case), and there was consistency in the results, which shows that the JHLES model is supported by the data. In the present study, the JHLES has been validated in a sample of dental students for the first time in Poland and Europe. Our study provided good evidence for the reliability and validity of the Polish version of the JHLES. In conclusion, the Polish-language version of the JHLES questionnaire is a reliable and valid instrument for analysing the learning environment for students, and its factor structure is supported by the data.

Validation of the Behçet's Syndrome Overall Damage Index (BODI) for Retrospective Studies and a Proposal for Modification.

Assessment of damage accrual over time is important for evaluating and comparing long-term results of treatment modalities and strategies. Retrospective studies may be useful for assessing long-term damage, especially in rare diseases. We aimed to validate Behçet's Syndrome Overall Damage Index (BODI) for use in retrospective studies by evaluating its construct validity, reliability, and feasibility in retrospectively collected data. Additionally, we aimed to determine missing items by evaluating Behçet's syndrome patients with different types of organ involvement and long-term follow-up. We included 300 patients who had at least 2 clinic visits at 1-year intervals. The construct validity for use in retrospective trials was assessed by comparing BODI scores calculated from patient charts and during face-to-face visits. BODI was additionally scored using retrospective chart data by 2 different observers and by the same observer six months apart, in a blinded manner. The time for filling BODI was evaluated to assess feasibility. Additionally, damaged items that were missing from BODI were identified. There was a good correlation between the retrospective and face-to-face evaluation of BODI (ICC 0.99; %95 CI 0.99-0.99). Inter-observer and intra-observer agreement were good (ICC 0.96 and 1, respectively). The main damage items that BODI did not capture were hypertension, liver failure, lung parenchymal involvement, glaucoma, and lymphedema. BODI seems to be a reliable and feasible instrument for assessing damage in retrospective studies. Modifying BODI using the additional damage items identified in this study may make it an even better scale.

THE INDONESIAN LINGUISTIC VALIDATION OF THE URINARY STENT RELATED HEALTH QUESTIONNAIRE

Objective: To validate the Indonesian version of the urinary stent related health (UriSteRH) questionnaire. Material & Methods: The Indonesian version of the UriSteRH was developed with multistep process by urologist, two nursing lecturers and two independent translators. A total 13 patients with indwelling DJ Stent completed the Indonesian UriSteRH questionnaires on the 30th day after Stenting. The reliability of the Indonesian version was evaluated using Cronbach’s alpha test. Domain structures were examined by using Pearson correlation coefficient (R). Results: Urinary pain, body pain, physical activity, social life, mental health, sexual activity and quality of life showed good internal consistency. There were strong correlations of physical activity (r=0.851) and social life (r=0.815) with the quality of life (r=0.736). In addition, there were moderate correlation of mental health general (r=0.676) related to urinary pain (r=0.612) and body pain (r=0.567). However, sexual activity had a lower correlation (r=0.456). Conclusion: The Indonesian version of UriSteRH is a reliable and valid instrument to evaluate health and quality of life in patients with indwelling DJ Stent. Keywords: DJ Stent, indonesian validation, questionnaire, urinary stent related health .

Optical Properties and Possible Origins of Atmospheric Aerosols over LHAASO in the Eastern Margin of the Tibetan Plateau

The accuracy of cosmic ray observations by the Large High Altitude Air Shower Observatory Wide Field-of-View Cherenkov/Fluorescence Telescope Array (LHAASO-WFCTA) is influenced by variations in aerosols in the atmosphere. The solar photometer (CE318-T) is extensively utilized within the Aerosol Robotic Network as a highly precise and reliable instrument for aerosol measurements. With this CE318-T 23, 254 sets of valid data samples over 394 days from October 2020 to October 2022 at the LHAASO site were obtained. Data analysis revealed that the baseline Aerosol Optical Depth (AOD) and Ångström Exponent (AE) at 440–870 nm (AE440–870nm) of the aerosols were calculated to be 0.03 and 1.07, respectively, suggesting that the LHAASO site is among the most pristine regions on Earth. The seasonality of the mean AOD is in the order of spring > summer > autumn = winter. The monthly average maximum of AOD440nm occurred in April (0.11 ± 0.05) and the minimum was in December (0.03 ± 0.01). The monthly average of AE440–870nm exhibited slight variations. The seasonal characterization of aerosol types indicated that background aerosol predominated in autumn and winter, which is the optimal period for the absolute calibration of the WFCTA. Additionally, the diurnal daytime variations of AOD and AE across the four seasons are presented. Our analysis also indicates that the potential origins of aerosol over the LHAASO in four seasons were different and the atmospheric aerosols with higher AOD probably originate mainly from Northern Myanmar and Northeast India regions. These results are presented for the first time, providing a detailed analysis of aerosol seasonality and origins, which have not been thoroughly documented before in this region, also enriching the valuable materials on aerosol observation in the Hengduan Mountains and Tibetan Plateau.

Translation, cross-cultural adaptation and psychometric properties of the Urdu version of the back pain functional scale in low back pain patients.

Translation and validation of important scales in other languages reduce bias in reporting the functional status of the patient. To translate the Back Pain Functional Scale into Urdu (BPFSu), adapt it for use in other cultures, and evaluate its psychometric properties. According to Beaton guidelines, translation and cultural adaption was carried out. On 100 Urdu-literate men and women aged 18-60years with lower back pain, the final BPFSu was assessed for psychometric qualities. First at baseline and again after 7days, participants completed the BPFSu, the Functional Rating Index (FRI), and the Numeric Pain Rating Scale (NPRS). Internal consistency of the BPFSu was excellent (Cronbach's alpha: 0.937). No floor and ceiling effects were found Excellent test-retest reliability (ICC = 0.882, CI 95%; 0.830-0.919) was achieved. Spearman correlation coefficient showed criterion validity with the NPRS (rho =â⁢⁢0.701, p⩽ 0.001) and Pearson correlation coefficient showed construct validity with the FRI (r=â⁢⁢0.740, p⩽ 0.001). The minimum detectable changes were 9.96, while the standard error of measurement was 3.6. The BPFSu is a valid and reliable instrument for assessing physical function in individuals experiencing low back discomfort.
