Development and Validation of Sensitivity for Needs of Elderly Scale Among Caregivers Based on Maslow’s Theory

The world currently lives in an aging society. Demand for elderly caregivers and services is rapidly rising. Elderly care encompasses not only medical care, but also the art of human care. Love and respect are usually considered the backbone of the modality of caregivers. This study aimed at developing a sensitivity for needs of elderly scale (SNES) among caregivers. Maslow’s theory of hierarchical needs, especially stage 3 (love and belongingness needs) and stage 4 (esteem needs), was used as a conceptual framework. This study consisted of four steps. The sample groups for the first two steps of item quality and exploratory factory analysis were 420 nursing students. A three-factor model emerged, which includes the sensitivity of needs for love and empathy, the sensitivity of needs for respect, and the sensitivity of needs for honor and dignity. The newly constructed measure consisted of 10 items, which explained the variance by 52.18%. The third step of confirmatory factor analysis, using a new group of 384 nursing students, indicated the model fit. In the final step, the scale was validated using 171 elderly caregivers. Moderate to strong absolute magnitudes of correlations between the new scale and psycho-moral strength, core self-evaluation, future orientation and self-control, moral disengagement, and caring behavior were found. Incremental validity was tested. Discussion and recommendations for further research and implications of the newly constructed measure were offered.

Living Group Climate in Kosovo and Albania: Internal Structure and Reliability of the Prison Group Climate Instrument (PGCI)

ABSTRACT This study examined the internal structure and internal consistency reliability of the Prison Group Climate Instrument (PGCI), by means of confirmatory factor analysis (CFA) and reliability analyses in a sample of 195 minors (92.8% male; aged 14–24; M = 17.6, SD = 1.52) in Kosovo and Albania. Findings showed an acceptable model fit for a three-factor model consisting of three correlated factors with good internal consistency reliability: Support (ω = .93), Growth (ω = .86), and Atmosphere (ω = .83), rather than the original four-factor model. The repression subscale did not fit participant’s perception, possibly due to cultural values favoring authority and respect for the rules. PGCI can be used to assess and monitor living group climate from the perspective of rehabilitation, facilitating future scientific research and continuous improvement of forensic residential care in these countries.

Transdiagnostic Attentional Deficits Are Associated with Depressive and Externalizing Symptoms in Children and Adolescents with Neuropsychiatric Disorders.

Although inattention, impulsivity, and impairments to vigilance are most associated with attention-deficit/hyperactivity disorder (ADHD), transdiagnostic attentional deficits are prevalent across all psychiatric disorders. To further elucidate this relationship, the present study investigated parent-reported neuropsychiatric symptom correlates of attention deficits using the factor structure of the Conners' Continuous Performance Test (CPT-II), a neuropsychological test of attention. Two-hundred and eighteen children and adolescents (7-21years old) completed the CPT-II as part of standard clinical protocol during outpatient pediatric neuropsychology visits. The factor structure of the CPT-II was determined with a principal component analysis (PCA) using Promax rotation. Pearson correlation analyses and regression models examined the relationship between the generated factor structure, parent-reported clinical symptoms, and pre-determined clinical diagnoses. Results from the PCA suggested a three-factor model best supported the structure of the CPT-II, and were subsequently defined as inattention, impulsivity, and vigilance. Performance-based inattention was significantly correlated with parent-reported hyperactivity, aggression, conduct problems, and depression. Parent-reported depressive symptoms and conduct problems were the strongest correlates of performance-based inattention, not hyperactivity or aggression. Performance-based inattention was significantly associated with an ADHD diagnosis but not a depression or anxiety diagnosis. Findings suggest attentional deficits are not specific to any one disorder. To enhance the identification, classification, and treatment of neuropsychiatric disorders, both researchers and clinicians alike must diminish the importance of categorical approaches to child/adolescent psychopathology and continue to consider the dimensionality of transdiagnostic characteristics such as inattention.

Psychometric Properties of the Basic Needs Satisfaction in General Scale: A Second-Order CFA Analysis

The study examined the psychometric structure of Basic Needs Satisfaction in General Scale (BNSG-S) with a sample of 495 college students. It compared the original 21-item version (Gagné, 2003) with the shortened 16-item version (Johnston & Finney, 2010), both with and without method effects. A series of confirmatory factor analyses (CFA) suggested a three-factor CFA model with method effect using the 16-item version showed acceptable model-data fit. However, the high correlations among factors posed threats to the discriminant validity. To address the multicollinearity among the factors, our study proposed and tested a second-order CFA model with method effect based on the 16-item shortened version of BNSG-S, which provided good model-data fit. Additionally, Cronbach’s alpha and omega coefficients demonstrated satisfactory reliability. These results supported a higher-order factor structure of the 16-item version, suggesting the needs satisfaction may be interconnected and influenced by a broader overarching factor.

Adaptation of the ‘’Food Allergy Self-Efficacy Scale for Parents’’(FASE-P) to Turkish: a validity and reliability study

Background. Food allergy is a public health issue that has a significant impact on the lives of families. Parental self-efficacy/confidence is important in managing food allergies. The aim of this study is to validate the “Food Allergy Self-Efficacy Scale for Parents” (FASE-P) and assess parental self-efficacy in managing their child’s food allergy. Methods. Turkish version of the FASE-P (T-FASE-P) was administered to 347 parents of children aged 0-18 who had been followed for at least one month due to food allergy at the Pediatric Allergy Clinic of Prof. Dr. Cemil Taşcıoğlu City Hospital between September 1 and December 31, 2023, through face-to-face interviews and online surveys for parents of children with food allergies from the general population. Content validity, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA) were conducted to evaluate the validity of the scale. General Self-Efficacy Scale (GSES) was used for concurrent criterion validity. Internal consistency analysis, test-retest application, and item analysis were conducted to assess its reliability. Results. T-FASE-P scale initially contained 21 items, and the Cronbach’s alpha coefficient (α) calculated in this form was found to be 0.89. Later, when 4 items were excluded, the 17-item version of the scale was calculated as α=0.90. The intra-class correlation coefficient between the test and re-test was found to be 0.972. The content validity index value of the scale was calculated as 0.99, indicating that the content validity was at a sufficient level. In the EFA, it was determined that the scale formed a three-factor structural model and that this model explained 60.82% of the total variance. As a result of the CFA, the fit indices were calculated as χ2/df=2.341, GFI=0.919, TLI=0.950, indicating a good level of fit. Based on the analysis results, T-FASE-P consists of 17 items and three subscales. Conclusion. T-FASE-P scale is a valid and reliable measurement tool that can be used to determine the food allergy self-efficacy of Turkish parents.

Validating the foreign language enjoyment scale for young learners: An exploratory structural equation modeling approach

Foreign language enjoyment (FLE) has garnered scholarly attention within the framework of positive psychology. However, FLE-related studies have predominantly focused on adult learners, with little exploration into FLE among young language learners (YLLs). Consequently, little is known about the factorial structure of FLE and its sources for YLLs. This study aims to develop and validate the foreign language enjoyment scale (FLES) designed for YLLs by comparing four models: confirmatory factor analysis (CFA), bifactor CFA, ESEM, and bifactor ESEM, based on Alamer's (2022) guidelines for ESEM. 510 Japanese elementary ESL learners in the 5th and 6th grades participated in this study. The analysis of the four models revealed that the bifactor ESEM outperformed the others in terms of model fit and comparative indices, identifying a three-factor model of FLE, which is consistent with prior studies on adult learners. The findings from this study not only contribute to further understanding of FLE within a less-studied population but also advance methodological approaches for scale validation in applied linguistics.

Adaptation of the Problem Areas in Diabetes-Teen Scale into Turkish and examination of its psychometric properties: a validity and reliability study

Objective. Management of type 1 diabetes (T1DM) is quite challenging for both adolescents and their families. In this study, we aimed to translate the 14-item Problem Areas in Diabetes-Teen (PAID-T) scale, which measures variables that influence diabetes distress, to Turkish and investigate the Turkish version’s reliability and validity. Methods. One hundred and ninety-four adolescents with T1DM participated in the study. PAID-T and forms for sociodemographic and diabetes characteristics were used for data collection. The scale’s content validity was checked using the Davis technique. Cronbach’s α was used to analyze the scale’s internal reliability and the test-retest for the scale’s reliability. Exploratory factor analysis (EFA) was utilized to examine the factor structure. The fit of the scale was assessed using confirmatory factor analysis (CFA). Results. Of the participants, 54.6% (n=106) were girls. The content validity index values of the scale items ranged between 0.86 and 1.0. The PAID-T scores of girls and boys were similar. No significant difference was found between PAID-T scores with sociodemographic data and diabetes characteristics (p>0.05). The test-retest correlation coefficient of the scale was found to be 0.952. The three-factor (emotional burden, family and friend distress, and regimen-specific distress) model identified in EFA explained 61.8% of the common variance. Fit analysis was performed using CFA for the three-factor model, which did not show adequate fit (x2/df = 2.402, GFI = 0.822, CFI = 0.815, NFI = 0.727, NNFI = 0.772, RMSEA = 0.118). The Cronbach α value of the scale was 0.864. Conclusion. The Turkish version of the 14-item PAID-T showed moderate validity and strong reliability. Accordingly, it can be used as a reliable measurement tool to assess diabetes stress in adolescents with T1DM.

Optimal Number of Replications for Obtaining Stable Dynamic Fit Index Cutoffs

Factor analysis is commonly used in behavioral sciences to measure latent constructs, and researchers routinely consider approximate fit indices to ensure adequate model fit and to provide important validity evidence. Due to a lack of generalizable fit index cutoffs, methodologists suggest simulation-based methods to create customized cutoffs that allow researchers to assess model fit more accurately. However, simulation-based methods are computationally intensive. An open question is: How many simulation replications are needed for these custom cutoffs to stabilize? This Monte Carlo simulation study focuses on one such simulation-based method—dynamic fit index (DFI) cutoffs—to determine the optimal number of replications for obtaining stable cutoffs. Results indicated that the DFI approach generates stable cutoffs with 500 replications (the currently recommended number), but the process can be more efficient with fewer replications, especially in simulations with categorical data. Using fewer replications significantly reduces the computational time for determining cutoff values with minimal impact on the results. For one-factor or three-factor models, results suggested that in most conditions 200 DFI replications were optimal for balancing fit index cutoff stability and computational efficiency.

The Behavior Problem Inventory-Short Form: Psychometric Properties in a Spanish Sample of Intellectual Disabilities.

Behavioural problems in individuals with intellectual disabilities have a negative impact on them. Limited assessment measures exist in Spain. This study aimed to validate the Behavior Problems Inventory-Short Form (BPI-S) in the Spanish population by examining its psychometric properties and factorial structures. This study included 458 individuals with intellectual disabilities evaluated by 137 professionals. The validity and reliability of the scale were examined. The validity of the measurement tool confirmed a three-factor model. Significant correlations were observed between problem behaviours and maladaptive behaviour indicators, with negative associations found between problem behaviours and adaptive behaviour scores. The Spanish version of the BPI-S demonstrated good internal consistency and convergent and discriminant validities. The most common behaviours were identified, and the scale was refined to 28 items. The three-factor model showed an acceptable fit. Further research is required to establish clinical norms and explore the factorial structures.

Cultural normative beliefs in the U.S. as a determinant of negative dental experiences and dental anxiety: a preliminary investigation

AbstractDental anxiety, a predictor of both dental treatment avoidance and health outcomes, has been linked with early negative dental experiences. The causes of this relationship remain largely unexplored. This study provides a preliminary exploration of within-cultural variations of dental normative beliefs on the perception of negative dental experiences and the subsequent experience of dental anxiety in the U.S. A sample of 190 U.S. adults recruited from Amazon’s MTurk completed measures of cultural normative beliefs about oral health care, age and fear at first dental visit, history of negative dental experiences, and dental anxiety. Factor analysis yielded support for a three-factor model (daily maintenance, regular check-up, and dental treatment) of the dental cultural normative beliefs scale. Correlations and structural equation modeling found support for a previously posited theoretical model in which negative dental experiences and fear at first dental visit mediate associations between the cultural normative beliefs and dental anxiety. Most notably, cultural normative beliefs favoring a prevention orientation to dental treatment and daily maintenance of oral health predicted less fear at the first dentist visit, which in turn, related to fewer negative dental experiences and less dental anxiety. This preliminary survey suggests that dental cultural normative beliefs within the U.S. shape fear during initial dental visits. Future research should build on this initial work and explore between-cultural norm variations as well as strategies for changing cultural normative beliefs to improve perceptions of dental experiences and lessen dental anxiety.

Competing Models of the Structure of Subjective Well-Being: Have All Won and Must All Have Prizes?

The tripartite model of subjective well-being (SWB) posits three components: positive affect, negative affect, and life satisfaction. The fundamental issue regarding the structure of SWB and the meaning of the general SWB factor remains unresolved. Across three studies and six samples (total N = 9304), we evaluated competing models of SWB and tested the criterion-related validity of SWB components operationalized within different models. In addition to a standard confirmatory factor analysis (CFA) and bifactor-CFA, we used exploratory structural equation modeling (ESEM) and bifactor-ESEM approaches. Latent factor models were applied to examine the nomological network of SWB in relation to several external criteria (e.g., positive expectations, depression, and anxiety). We found evidence supporting the three-factor and bifactor-ESEM models of SWB. The meaning and interpretability of the general and specific factors of SWB were found to depend on the indicators used to assess affective well-being. Several issues concerning the bifactor-CFA model were identified. Both the general and specific factors of SWB exhibited meaningful and interpretable nomological networks. The structure of SWB, the value of incorporating a general factor, and the nature of general and specific SWB factors depend on the instruments used to measure SWB.

Cross-cultural adaptation and validation of a revised Italian Anterior Knee Pain Scale version.

The study aimed to validate a revised Italian version of the Anterior Knee Pain Scale (AKPS) by addressing shortcomings in previous adaptations and following the COSMIN guidelines to ensure robust psychometric evaluation. One hundred thirty patients with anterior knee pain symptoms were recruited, with 65 undergoing a retest after 7 days to assess the scale's reliability. Structural validity was assessed through confirmatory factor analysis (CFA) to evaluate the scale's dimensionality. Internal consistency was measured using Cronbach's alpha, while test-retest reliability was assessed using the intraclass correlation coefficient (ICC). Measurement error was evaluated using the standard error of measurement (SEM) and the smallest detectable change (SDC). Construct validity was examined by correlating the AKPS with other established scales, including the Knee Injury and Osteoarthritis Outcome Score, Internal Knee Documentation Committee, Victorian Institute of Sport Assessment - Patella, Short-Form 36 Health Survey, and the Visual Analogue Scale. The CFA supported a three-factor model encompassing pain intensity and interference, functional limitations in daily activities, and knee structural and functional issues. The scale demonstrated good internal consistency (Cronbach's α=0.79) and excellent test-retest reliability (ICC=0.91), with low measurement error (SEM<5%). Construct validity was confirmed through moderate-to-strong correlations with related scales, particularly in domains related to pain intensity, symptoms, and daily functioning. The newly validated scale, demonstrating strong psychometric properties, meets international standards for clinical assessment tools, making it a reliable and effective instrument for assessing anterior knee pain in the Italian context.

Psychometric properties of the Child Anxiety and Depression Life Interference Scale - Young Adult version.

A life interference measure specifically designed for young adults with anxiety and depressive symptoms does not currently exist. This paper describes the development and psychometric evaluation of a brief self-report measure of life interference associated with young adult anxiety and depression, the Child Anxiety and Depression Life Interference Scale - Young Adult version (CADLIS-YA). Cross-sectional, correlational and exploratory factor analysis (EFA). Five-hundred and thirty-two participants aged 18-24 years recruited from an undergraduate and community sample completed the CADLIS-YA. An EFA supported a three-factor model describing the impact of young adult anxiety and depression on social life, family and daily life interference. Test-retest reliability and internal consistency were good to excellent. Convergent validity was demonstrated, and the scale differentiated between young adults with and without elevated anxiety and depressive symptoms. Support for divergent validity was limited. The CADLIS-YA is a reliable and valid life interference measure for young adults with symptoms of anxiety and depression. It is potentially suitable for administration in low-resource research settings and it has promise for use in clinical settings; however, it needs validation in a clinical sample.

Fear of Relapse Scale: Spanish version and psychometric characteristics in a sample of patients with Relapsing-Remitting multiple sclerosis

IntroductionRelapses are a hallmark of multiple sclerosis, being a characteristic feature of relapsing-remitting multiple sclerosis (RRMS). The occurrence of a relapse constitutes a source of significant discomfort that impacts all domains of daily life of patients with multiple sclerosis (PwMS). In this study we first explored the psychometric properties of the Spanish version of the Fear of Relapse Scale (FoR) in a sample of patients with RRMS. Besides, we explored the relationship between the Fear of Relapse Scale with fatigue and cognitive perceived deficits in our PwMS sample. MethodsAn online cross-sectional survey was conducted on 173 MS patients from 12 Spanish-speaking countries (Argentina, Mexico, Uruguay, Dominican Republic, Spain, Cuba, Colombia, Guatemala, Chile, Paraguay, Peru, and El Salvador). Confirmatory factor analysis (CFA) was performed to assess the factor structure of the scale. Multiple linear regression was used to evaluate the effects of health self-perception, fatigue, and perceived cognitive deficits over fear of relapse. ResultsThe three-factor model in the CFA yielded a good model fit (χ2/df = 2.25, P < .001, RMSEA = .078, CFI = .91). McDonalds’ Omega of the FoR (Spanish version) was .91. There was a statistically significant inverse correlation between FoR and health self-perception, and a positive correlation between FoR, fatigue, and perceived cognitive deficits. Finally, level of fatigue was a predictor of fear of relapse. ConclusionsThe Spanish version of the Fear of Relapse Scale is a valid and reliable instrument to explore the experience of fear of relapse in patients with RRMS.

Development and reliability and validity testing of a medication literacy scale for medical college students

BackgroundIrrational drug use has become a global problem threatening human health. As future health professionals, medical college students’ medication literacy (ML) is critical. Their mastery of medication-related knowledge will directly affect public medication safety in the future.MethodsThe initial scale was developed through a literature review and was modified through expert consultation and student interviews to form the initial scale with 14 items. In 2020, a questionnaire survey was conducted among students in a medical college for item analysis, reliability test, validity test and other analyses.ResultsThe total Cronbach’s α coefficient was 0.826 and split-half reliability was 0.852. The Cronbach’s α coefficients for functional medication literacy, communicative medication literacy, and critical medication literacy were 0.901, 0.858, and 0.851, respectively. The item-level content validity index (I-CVI) ranged from 0.833 to 1.000 (≥ 0.78). Factor analysis of 14 items showed that KMO = 0. 852(> 0.7) and Bartlett’s spherical test p < 0.001, indicating that the data are very suitable for factor analysis. Three principal axis factors were extracted by principal component analysis, and the total variance interpretation rate was 69.031% (> 40%). The confirmatory factor analysis identified a three-factor model and showed goodness of fit indices for the scale: The χ²/df = 2.623, The Goodness of Fit Index (GFI) = 0.905, The Comparative Fit Index (CFI) = 0.950, Normed Fit Index (NFI) = 0.922, Tucker-Lewis index (TLI) = 0.938, and The Root Mean Square Error of Approximation (RMSEA) = 0.078.ConclusionA new scale for evaluating the medication literacy of Chinese medical college students was preliminarily developed, demonstrating good reliability and validity. Itcan be used as a preliminary measurement tool for assessing medical students’ medication literacy. However, due to the limitations of this study, the practical application of the scale needs to be further examined in a larger sample and should be refined in future studies.

Test Anxiety Among Czech Pupils in Lower-Secondary Education

Test anxiety remains a compelling focus of contemporary research. This attention may be, in part, due to the continued reliance on high-stakes testing, which plays a pivotal role in students' academic trajectories. Our research had several objectives. Given the lack of research on test anxiety in the Czech Republic, our primary aim was to adapt and validate the Children's Test Anxiety Scale (CTAS) on a sample of 740 lower-secondary students (ages 13-15). The results demonstrated adequate construct validity, supporting the three-factor model of the CTAS. Moreover, we investigated the relationship between test anxiety, academic self-concept, and educational outcomes alongside other demographic variables. Our findings revealed a strong negative correlation linking students' academic self-concept and test anxiety. Although no direct correlation emerged between test anxiety and educational outcomes, a linear regression indicated a significant shift: educational outcomes (grades) became significant predictors when considered in conjunction with academic selfconcept. Additionally, our study confirmed a significant impact of gender on test anxiety levels (girls exhibited higher test anxiety than boys) and a modest but significant correlation with parental educational background.

Psychometric evaluation of the Geneva Sentimentality Scale in Chinese college students.

The Geneva Sentimentality Scale (GSS) measures the experience of being moved and its effects on behavior. Despite the prevalence of this emotional response, it has not been extensively studied in China. This study aims to adapt and revise the GSS for Chinese college students to assess its cross-cultural consistency. A sample of 1328 students aged 18-24 years participated in the study, with 127 randomly selected for retesting after an 8-week interval. Exploratory factor analysis reveals that the Chinese version of the GSS includes three factors (emotional labels, tears of joy, and warm feelings in the chest), with a total of nine items. The internal consistency coefficients for the three factors and the overall scale are high, and the total score remains stable over time. Confirmatory factor analysis (CFA) shows that the three-factor model has a good fit. Multigroup CFA indicates measurement invariance across genders. The results also demonstrate good discriminant and convergent validity for the scale. Overall, the GSS is a reliable and flexible tool for assessing the emotion of being moved among Chinese college students.

Validation of the Multidimensional Scale of Perceived Social Support among LGBT population in Serbia

Abstract Background Social support represents the belief that one is valued, cared for, and loved by others in a social network and a lack of it may lead to adverse outcomes such as a relapse into depression or emotional distress in physically ill patients. The Multidimensional Scale of Perceived Social Support (MSPSS) is an instrument aimed to measure an individual’s perception of how much he or she receives outside social support. This study aimed to examine the validity and reliability of the Serbian version of MSPSS in a sample of LGBT population in Serbia. Methods The cross-sectional study included 504 respondents, members of the LGBT population living in Serbia. The instrument used was the MSPSS as a self-report measure, containing twelve items rated on a 7-point Likert scale. MSPSS consists of three sub-scales: Family, Friends, and Significant Others. Exploratory (EFA) and confirmatory factor analyses (CFA) were performed with two independent random samples. Results The average score on the scale of social support was 5.58±0.84 (scale of social support by family 4.62±1.41, scale of social support by friends 5.93± 1.99, and scale of social support by the significant others 6.20±0.96, respectively). The Cronbach’s alpha for the entire social support scale was α = 0.772. The three-factor structure of the MSPSS was proved with EFA and CFA. The factor loadings varied between 0.630-0.817. The three factors explained a total of 52.68% of the variance (factor 1- 28.62%, factor 2. 13.16%, factor 3- 10,90%). The three-factor model was adopted during the CFA when the three-factor model CFI (comparative fit index) was 0.969. Conclusions The MSPSS has shown good reliability, internal validity and construct validity and can be used as a convenient measure of social support among the LGBT population. Both EFA and CFA yield a three-factor structure consistent with the theory underlying the measure’s development. Key messages • The results of the study suggest that the Multidimensional Scale of Perceived Social Support has acceptable psychometric properties for use with the LGBT population. • This study supports the use of the MSPSS for assessing community-based collaboration using the three-factor model among the LGBT population.

Study on the relationship between KCNQ1 gene-environment interaction and abnormal glucose metabolism in the elderly in a county of Hechi City, Guangxi.

This study aimed to understand the potassium voltage-gated channel KQT-like subfamily, member 1 gene polymorphism in a rural elderly population in a county in Guangxi and to explore the possible relationship between its gene polymorphism and blood sugar. The 6 SNP loci of blood DNA samples from 4355 individuals were typed using the imLDRTM Multiple SNP Typing Kit from Shanghai Tianhao Biotechnology Co. The data combining epidemiological information (baseline questionnaire and physical examination results) and genotyping results were statistically analyzed using GMDR0.9 software and SPSS22.0 software. A total of 4355 elderly people aged 60 years and above were surveyed in this survey, and the total abnormal rate of glucose metabolism was 16·11 % (699/4355). Among them, male:female ratio was 1:1·48; the age group of 60-69 years old accounted for the highest proportion, with 2337 people, accounting for 53·66 % (2337/4355). The results of multivariate analysis showed that usually not doing farm work (OR 1·26; 95 % CI 1·06, 1·50), TAG ≥ 1·70 mmol/l (OR 1·19; 95 % CI 1·11, 1·27), hyperuricaemia (OR 1·034; 95 % CI 1·01, 1·66) and BMI ≥ 24 kg/m2 (OR 1·06; 95 % CI 1·03, 1·09) may be risk factors for abnormal glucose metabolism. Among all participants, rs151290 locus AA genotype, A allele carriers (AA+AC) were 0.70 times more likely (0.54 to 0.91) and 0.82 times more likely (0.70 to 0.97) to develop abnormal glucose metabolism than CC genotype carriers, respectively. Carriers of the T allele at the rs2237892 locus (CT+TT) were 0.85 times more likely to have abnormal glucose metabolism than carriers of the CC genotype (0.72 to 0.99); rs2237897 locus CT gene. The possibility of abnormal glucose metabolism in the carriers of CC genotype, TT genotype and T allele (CT + TT) is 0·79 times (0·67-0·94), 0·74 times (0·55-0·99) and 0·78 times (0·66, 0·92). The results of multifactor dimensionality reduction showed that the optimal interaction model was a three-factor model consisting of farm work, TAG and rs2237897. The best model dendrogram found that the interaction between TAG and rs2237897 had the strongest effect on fasting blood glucose in the elderly in rural areas, and they were mutually antagonistic. Environment-gene interaction is an important factor affecting abnormal glucose metabolism in the elderly of a county in Hechi City, Guangxi.
