Adaptation and validation of the Adolescent Psychotic-like Symptom Screener (APSS-6) in Spain: evidence from adult population

BackgroundPsychotic-like experiences are common in the general population and an important indicator of psychological vulnerability. One of the used instruments for their assessment is the Adolescent Psychotic-Like Symptom Screener (APSS). However, there are few studies on the APSS psychometric characteristics in different cultural contexts. The aim of this study is to adapt the instrument in the Spanish context and analyze its psychometric properties in an adult population.MethodsUpon the translation and adaptation of the APSS to Spanish, a sample of 287 participants (19–60 years) completed the questionnaire online together with the Symptom Assessment-45 Questionnaire (SA-45) and an ad-hoc survey on clinical and sociodemographic variables. The sample was then randomly split into two halves, the first being the calibration (n = 144) and the second the validation sample (n = 143). An exploratory factor analysis was performed with the former, and a confirmatory factor analysis was performed with the latter, together with internal consistency and convergent validity analyses.ResultsThe APSS Spanish version presents a unifactorial structure comprising 6 out of the 7 original items with adequate fit and good internal consistency. This single factor structure is invariant across age, sex and history of self-reported psychopathology. The instrument also shows significant positive correlations with the SA-45 psychoticism and paranoid ideation subscales.ConclusionsTo the best of our knowledge, this is the first study that has conducted a psychometric analysis of the APSS in adult population. The Spanish version of the APSS shows adequate reliability, construct and convergent validity in adults, therefore provides a handy tool to be used for the screening of psychotic-like experiences in the Spanish general population.

Preliminary construction and validation of a questionnaire on adolescents' personal growth proactivity

The questionnaire was administered in middle schools and data from 944 valid participants were obtained, randomly divided into two parts. Sample one (N=472) was used for exploratory factor analysis, and sample two (N=472) was used for confirmatory factor analysis. The results indicated that the Adolescent Personal Growth Proactivity Questionnaire consists of 24 items, which are categorized into five factors: Growth Internality, Growth Autonomy, Growth Self-Determination, Growth Seeking, and Growth Externality. The questionnaire demonstrated good reliability and validity.

Psychometric Properties of the Malay Suicidal Behaviors Questionnaire-Revised (SBQ-R) in Malaysian Undergraduates.

The psychometric properties of the Malay Suicidal Behaviors Questionnaire-Revised (SBQ-R) need to be tested as it is increasingly utilized, and there is a lack of a brief, validated scale to examine suicidal behaviors in Malaysia. A total of 713 and 715 undergraduates answered the English and Malay SBQ-R, respectively. Exploratory factor analysis derived a one-factor solution, with a total explained variance of 58.0% accounted for by the four items. Confirmatory factor analyses supported the one-factor model for the Malay SBQ-R, with acceptable fit indices (χ2/df = 0.451, comparative and Tucker-Lewis fit indices = ≥1.000, standardized root mean square residual = 0.014, root mean square error of approximation = 0.000, and 90% CI [0.000, 0.083]). Measurement invariance was achieved when comparing the SBQ-R between the English and Malay versions, indicating that both versions are similar in Malaysian undergraduates. Convergent validity was established through a strong correlation between the Malay SBQ-R and the Malay Yatt Suicide Attitude Scale (r = 0.74; p < 0.001). Good internal consistency was achieved for both the English (α = 0.83; ω = 0.85) and Malay (α = 0.81; ω = 0.84) versions. The Malay SBQ-R has adequate validity and reliability for use in Malaysian undergraduates.

What Instigates the Feeling of Monday Blues Among Employees.

The present research aims to explore the factors that contribute to the feeling of Monday Blues among employees in medium and top-level management positions across various industries in Mumbai (India). Fourteen facets were identified from the responses of 50 employees, which were used to finalize the contents of a questionnaire. Data was collected from 181 employees, and Exploratory Factor Analysis revealed three main factors: motivation to work, work environment, and work stress. These factors were then used as independent variables in a regression analysis with Monday Blues as the dependent variable. The results showed that motivation to work and work environment had an inverse impact on Monday Blues, while work stress had a direct impact on feelings of the Monday Blues.

Development of the Indonesian sexual quality of life scale for women (ISQOL-W)

Sexual quality of life is greatly influenced by sexual function, yet thorough measures remain limited and vary across regions. In Indonesia, diverse cultural and religious contexts notably shape sexual quality of life. Thus, it is important to have a tool that considers both internal and external aspects. The aim of this study was to develop a valid and reliable scale that specifically measures Indonesian sexual quality of life for women (ISQOL-W), considering cultural and social factors. A total of 228 participants were recruited from April 30, 2023, to September 30, 2023. The ISQOL-W was developed through two phases: item generation and psychometric evaluation. In the first phase, 68 items were drafted based on definitions and dimensions of sexual quality of life. In the second phase, exploratory factor analysis resulted in 34 items with a loading factor greater than 0.4 (ranging from 0.41 to 0.84) which were categorized into four domains/factors: sexual-related emotion, sexual fantasy, sexual arousal, and sexual relationship. The Cronbach’s α coefficient for the overall questionnaire was 0.915, with subscale reliability ranging from 0.826 to 0.903. Further analysis revealed significant differences in ISQOL-W scores across relationship status, educational level, history of last sexual activity, and type of sexual activity. In conclusion, the ISQOL-W demonstrated robust psychometric properties, supporting its use in future studies. This study represents the first effort to develop and validate a sexual quality of life scale specifically for Indonesian women.

The Importance of Knowledge of Study Techniques and Their Impact on Academic Performance

Objective: The main objective of the research is to identify the role of knowledge about study techniques and its impact on the academic performance of students of the Academic Unit of Accounting and Administration (UACYA) at the Autonomous University of Nayarit (UAN). With the results obtained, it will be possible to demonstrate the importance of training them in this subject and make proposals for improvement. Achieving benefits for the student, being a conscious and responsible subject of their cognitive processes and the construction of their knowledge. Theoretical Framework: The conceptualization of meaningful learning is presented, from its precursor David Ausubel (1969), in which the individual is the constructor of his own knowledge, relating the concepts to be learned and with the information he already possesses. Achieving this, the guideline is given to obtain self-regulated learning, where learners are able to plan, control and direct their own learning, through metacognitive, motivational and behavioral processes. Supported by the use of strategies of study habits and techniques that allow them to meet their objectives and impacting their academic performance. Method: A non-experimental design was used, since there was no control with the variables under study, and it was also of a transectional correlational type, since the correlations between the factors under study were analyzed. The students analyzed were those who were found in the facilities of the Academic Unit of Accounting and Administration, so the type of sampling was of convenience, achieving a sample of 328 students. To analyze the correlations, the exploratory and confirmatory factor analysis was used, where first a divergent and convergent analysis was performed, then the reliability analysis, and once the instrument was validated, the exploratory factor analysis was performed, which used the AMOS (Analysis of Moment Structures) software for the confirmatory analysis and adequacy of the model. Results and Discussion: When applying the factor analysis, it was found that the variables were correctly grouped in three components, with a result of 56.478% of the total variance, being acceptable for the social studies, subsequently the KMO test was 0.799 and Bartlett's sphericity was less than .001, confirming the analysis. After elimination of items (p3 and p4) in the Confirmatory Factor Analysis, the fit indices complied with the acceptable values of CFI and RMSEA, obtaining a final adjusted and valid model, i.e. three consistent and relevant dimensions for future research. Research Implications: The practical and theoretical implications of this study highlight the importance of seeking strategies to generate in higher level learners the knowledge about study habits and techniques, which will lead them to be able to manage their own knowledge, and therefore fulfill their academic objectives. At the same time to seek to promote further educational research on issues related to meaningful and self-regulated learning. Originality/Value: This study contributes to the literature by demonstrating the importance of understanding the study habits and techniques of higher education students, and how their application in the learning process impacts academic performance. It sets the guideline for higher education institutions to develop in their students the ability to manage their own knowledge.

An Index to Identify and Classify the Spectrum of U.S. Peri-Urban Informal Subdivisions

This paper proposes a replicable, data-driven index to identify informal subdivisions and measure levels of peri-urban housing informality. Dallas (Texas) and Catawba (North Carolina) county assessment data, a review of the literature, and insights from qualitative research in North Texas yielded variables which were reduced to two factors through exploratory factor analysis. We identified 128 and fifty-three highly informal subdivisions in Dallas and Catawba counties, respectively. This work highlights the pervasiveness of peripheral informal subdivisions and helps guide planners’ efforts to locate and assist the most precarious subdivisions.

QOL-21. PSYCHOMETRIC VALIDATION OF THE FEAR OF CANCER RECURRENCE INVENTORY FOR PRIMARY BRAIN TUMOR PATIENTS

Abstract BACKGROUND Fear of cancer recurrence and progression (FCR) is a significant concern among those living with primary brain tumor and may be distinct compared to FCR in other cancer populations due to poorer prognosis, neurologic symptoms, and often lifelong treatment. The gold-standard comprehensive assessment tool for FCR–the FCR Inventory (FCRI)–includes 42 items with seven subscales. Validation of the FCRI scale excluded those with primary brain tumors. The present study is the first examination of the psychometric properties of the full FCRI in a heterogeneous sample of patients with primary brain tumors. METHODS Adult patients with primary brain tumors (n=334) completed the FCRI, with six additional brain tumor-specific items, and psychological, medical, and demographic questionnaires. In accordance with best practices of measure development, exploratory factor analysis (EFA) was conducted on the FCRI at the subscale level. Correlations investigated construct validity. RESULTS EFA largely supported the overall psychometric properties of the original FCRI. Several subscales were unchanged: Psychological Distress, Functioning Impairments, Insight, and Reassurance. One brain tumor-specific item (researching treatments) exhibited good fit on the Coping Skills subscale. On the Severity subscale, one item (belief that the tumor will not return) did not fit with an otherwise strong one-factor model. Additionally, five new brain tumor-specific items demonstrated good fit with the Triggers subscale. The resultant FCRI-Brain includes 41 original FCRI items plus six new brain tumor-specific items. FCRI-Brain demonstrated good convergent validity with measures of depression (r=.72), anxiety (r=.75), and death anxiety (r=.80; ps&amp;lt;.05). CONCLUSIONS This is the first validation of the comprehensive FCRI in patients with primary brain tumors. Factor analysis identified a theoretically similar and brain-tumor specific seven-factor model for the FCRI-Brain. Item-level and subscale statistics will be presented, including factor iteration and construction. Future work will use the FCRI to investigate FCR intervention efficacy in neuro-oncology.

Non-modifiable and Modifiable Risk Factors in Vascular Ageing Extremes: The African-PREDICT Study

BackgroundCardiovascular risk factors accelerate vascular ageing beyond chronological age, hence early vascular ageing (EVA). Carotid to femoral pulse wave velocity (cfPWV) is a measure of vascular ageing and is used to identify EVA and supernormal vascular ageing (SUPERNOVA). Vascular ageing is not completely understood in African populations. Therefore, we aimed to phenotype young South African adults stratified by cfPWV extremes in terms of non-modifiable and modifiable risk factors. This study included 1133 young adults (mean age: 24.5 years). We measured cfPWV using applanation tonometry. Body composition measures, self-reported 24-h dietary intake, smoking and alcohol consumption were included. Fasting blood samples were analysed for biochemical risk factors. Three groups based on cfPWV percentiles were compared and included SUPERNOVA (≤ 10th percentile), average vascular ageing (AVA, between 10 to 90th percentile) and EVA (≥ 90th percentile).ResultsChronological age, male sex, smoking, alcohol use, and blood pressure were incrementally higher across PWV groups (all p trend ≤ 0.007). Black ethnicity was higher (p = 0.038) in the SUPERNOVA group. In exploratory factor analysis, a factor pattern including mean arterial pressure and fasting glucose showed beneficial odds (OR 0.62, p = 0.002) for SUPERNOVA and higher likelihood (OR 2.10, p < 0.001) for EVA. Another factor pattern of socio-economic status and total dietary fat showed lower odds (OR 0.64, p = 0.003) for EVA.ConclusionPoor lifestyle behavioural risk factors seem detrimental in the EVA group conferring a possible higher risk of future CVD.

The Chinese version of the physical activity questionnaire for adolescents: a psychometric validity, reliability, and invariance study

BackgroundThe Physical Activity Questionnaire for Adolescents (PAQ-A) is one of the most commonly used questionnaires for assessing adolescents’ levels of moderate to vigorous physical activity (PA). Although a Chinese version of the PAQ-A (comprising nine items) exists, it has been assessed for only internal consistency coefficients, test–retest reliability, and correlations with the GT3X + accelerometer. Therefore, this study aimed to evaluate the psychometric properties of the Chinese version of the PAQ-A among Chinese adolescents.MethodsThis study included three samples of 1,101 secondary school students (12–19 years old). The first sample consisted of 518 participants (50.4% males, 49.6% females) for correlation tests and exploratory factor analysis (EFA). The second sample consisted of 227 participants (55.75% males, 44.24% females) for confirmatory factor analysis (CFA), convergent validity, and sample size invariance tests. The third sample consisted of 356 participants (54.50% male, 45.50% female) for the internal consistency reliability test, invariance test (cross sample size, education level and gender), and t-test.ResultsPearson correlation analysis of the PAQ-A indicated that all the total-item correlations exceeded 0.2, indicating good consistency across the items. Subsequent EFA of the Chinese version of the PAQ-A revealed a two-factor structure. CFA subsequently validated this structure. One of the items exhibited a standardized loading below 0.4 and was excluded. The exclusion of this item resulted in increased standardized loadings for the remaining items, ranging from 0.40 to 0.82, which indicates improved fit indices. This adjustment underscores the questionnaire’s satisfactory convergent validity and robust discriminant validity. The overall Cronbach’s alpha was 0.821, with the values for the first and second factors being 0.757 and 0.716, respectively. The questionnaire demonstrated stable invariance across sample sizes and education levels and additionally showed partial scalar invariance across genders. A t-test revealed a significant difference between males and females, which aligns with previous findings. These findings supported the construct validity of the questionnaire.ConclusionThis study validated the Chinese version of the PAQ-A for assessing adolescent PA in China, with a two-factor structure improved by removing one item.

Educational Experiences of the B’laan Tribe: Identifying Culturally Responsive and Contextual Factors in Learning

The study sought to determine the current learning experiences and conditions of B’laan tribe and identify factors associated with human capital development for B’laan tribe. Qualitative approaches were utilized in the first phase of the study. Focus Group Discussions (FGDs) and Key Informant Interviews (KII) were conducted to selected participants coming from the B’laan tribal chieftain (Fulong), representative from Barangay Council, representative from the Non-Government Organizations, and ordinary B’laan people from the community. Moreover, quantitative approaches were also used in this study in order to determine the factors derived from the qualitative data. Exploratory factor analysis (EFA) was used to establish the factors. A confirmatory factor analysis (CFA) using latent curve analysis of structural equation modeling was also utilized to confirm the validity of these dimensions as determinants of human capital development framework for B’laan tribe. The analysis uncovered a robust framework for human capital development for the B’laan tribe in education, noted with good fit indices. Further, model trimming exposed that two significant factors persist, hence appreciating that certain types of education like contextualized education and eco-based education are quite critical, yet not all that the B’laan desire. Results revealed themes centering on the current learning experiences and conditions of B’laan tribe through the curriculum implemented by the Department of Education is not culture sensitive. Peace and security were one of the factors that impeded education. The EFA revealed dimensions linked to human capital development framework for B’laan tribe which included free education, community resource- based education, contextualize-based education, human security-based education, right-based education, voice-based education, culture-based education, indigenous knowledge-based education, eco-based education, and sustainable education. All these factors were confirmed by CFA to constitute a valid framework of human capital development for B’laan tribe in the context of education.

An integrative approach to assessing buyer-supplier relationships: scale development and validation

PurposeThe research investigated relations between factors used to evaluate the quality of buyer-supplier relationships (BSRs): perceived performance of the supplier, satisfaction with supplier, and trust in the supplier; and to develop an instrument to evaluate BSRs (a BSRs evaluation scale).Design/methodology/approachWe applied the psychometric testing of the BSRs measurement using exploratory factor analysis and confirmatory factor analysis. We applied structural equation modeling (SEM) to understand the interrelations of factors underlying BSRs.FindingsThe BSRs evaluation scale consists of three factors: perceived performance of the supplier, satisfaction with the supplier, and trust in the supplier. The results provide empirical evidence of the validity, reliability, and generalizability of the presented measurement.Originality/valueThe study developed a novel measurement instrument that integrates BSRs’ multidimensional constructs. It explains and confirms the significant roles of satisfaction with the supplier, trust in the supplier, and perceived performance of the supplier in shaping the BSRs’ quality. Furthermore, we provide evidence that in BSRs goodwill- and competence-based trust integrate into a single factor.

A Novel and Comprehensive Wellness Assessment for Lifestyle-Based Interventions.

While weight status and clinical laboratory measures are important in assessing obesity-related disease severity and chronic disease risk, including a broader range of emotional, psychosocial, and behavioral factors would provide greater context of an individual's overall state of wellness and could be used to better guide treatment decisions. The purpose of this research was to develop a comprehensive Lifestyle Wellness assessment for use in lifestyle-based wellness interventions and programs. A cross-sectional exploratory factor analysis (EFA) was conducted using baseline data from N=138 adults participating in behavioral weight loss trials. An unweighted least squares extraction method with oblique rotation was used. Twenty-one putative measures spanning constructs related to metabolic health, emotional health/wellbeing, body weight and composition, diet quality, and fitness were analyzed for retention. Mean body mass index (BMI) was 38.0±6.6kg/m2, mean age was 57.3±11.1years, and 77.5% of participants were female. The EFA produced a five-factor model with 13 items that explained 80.3% of the variance. The retained factors included: (1) Psychosocial State: mindfulness, resilience, quality of life, and happiness; (2) Blood Pressure State: systolic and diastolic blood pressure; (3) Lipid State: total cholesterol and LDL-cholesterol; (4) Fitness State: grip strength, jump height, and percent body fat; and (5) Body State: BMI and waist circumference. Lifestyle Wellness is a comprehensive assessment that enables innovative wellness-related research such as metabolically healthy obese phenotypes and weight-neutral interventions. Future research should include investigations in additional populations with greater age, sex/gender, and body size diversity.

Constructing General Human Agency Indicators (GHAIs) and a General Personal Agency Scale (GPAS)

AbstractDespite its importance for the social sciences, human agency remains an ambiguous and underoperationalized construct. After engaging prior research to articulate clear criteria for defining agency and synthesize a multidimensional conceptual framework for human agency, this study develops and validates preliminary General Human Agency Indicators (GHAIs) to measure subconstructs within that framework. Utilizing the Midlife in the United States (MIDUS) dataset, we aggregated a list of 30 survey items previously used in agency research and conducted an iterative process of exploratory factor analysis (EFA) and item elimination to reduce that list to a set of 9–13 items with a strong, consistent factorial structure. Using confirmatory factor analysis (CFA), we identified two bifactor models that demonstrated good fit: a nine-item General Personal Agency scale (GPAS) and a nine-item GHAIs tool combining six items from the GPAS with three measuring agency achievement. Initial evidence for the construct validity of the tools was produced through tests of internal consistency and correlational analysis, indicating that the proposed GPAS and GHAIs effectively measure personal agency, intrinsic agency, instrumental agency, and agency achievement.

Development and Validation of Determinants of Marriage Delay Scale for women

Abstract The study was designed to develop and validate the Determinants of Marriage Delay Scale for Women in Pakistan. In light of the Exploratory and Confirmatory Factor Analysis, four determinants identified were Family Responsibilities and Financial Dependency, Socioeconomic and Physical Conditions, Cultural Expectations, and Personal and Psychological Concerns. The instrument revealed a highly reliable and content valid scale with high factor loadings, showing appropriate representation on each component. The scale thus integrates qualitative and quantitative approaches to provide a comprehensive and culturally sensitive tool for understanding complex influences on delays in the timing of marriage among women. This study explored not only how family-related factors, but also economic, cultural, and personal factors interactively shape the timing of marriage and offered a base for further research and policy interventions. The scale addresses such determinants and supports the formulation of specific strategies that can help women make appropriate decisions about marriage, which would meet both self and societal expectations. Keywords: Determinants, Marriage Delay, Women, Scale Development, EFA, CFA

QOL-23. MEASURING BODY FUNCTIONALITY APPRECIATION IN PATIENTS WITH PRIMARY BRAIN TUMORS

Abstract BACKGROUND Body image is a multifaceted construct consisting of thoughts, feelings, and perceptions about one’s body and its functioning. Perception of one’s own physical functioning and capabilities may be an important consideration in neuro-oncology given the sequalae of brain tumors and associated treatment; however, it is understudied in this population. One brief measure of body image, the Functionality Appreciation Scale (FAS) is a comprehensive tool, focused on one’s perceived physical functioning and capabilities, rather than perceived appearance. We aimed to examine the psychometric properties of the recently developed Functionality Appreciation Scale (FAS) among patients with primary brain tumors. METHODS Adult patients with primary brain tumors (N=237) completed the FAS and other measures of psychological distress as well as medical and demographic characteristics. An exploratory variance factor analysis (EFA) using principal axis factoring and a Promax rotation was conducted. Convergent validity was examined via correlations to measures of psychological distress. RESULTS The EFA supported the single-factor structure, which accounted for 62.71% of the variance with all items loading significantly onto this factor. The FAS had good internal consistency (Cronbach’s a=.90). Convergent validity was demonstrated by negative associations (ps&amp;lt;.05) with symptoms of depression (r=-.30), generalized anxiety (r=-.21), and death anxiety (r=-.17). CONCLUSION Results confirmed the single factor structure of the FAS in primary brain tumor patients. Furthermore, the expected negative relationships with measures of psychological distress provide evidence of convergent validity. The FAS is valid and reliable in patients with primary brain tumors. Our findings suggest that body functionality and appreciation may be important to target in psychosocial interventions for those with primary brain tumors.

Measuring subjective cognitive complaints with covid-19 brain fog using the subjective scale to investigate cognition (SSTICS)

The term “brain fog” has emerged from the observations of neuropsychiatric conditions present in post-COVID-19 infections. This is characterized by concentration and memory problems, selective attention disorders and difficulties in executive functions, yet it is unclear how long these deficits may persist and which cognitive functions are most vulnerable. Therefore, there is a need to properly evaluate these cognitive complaints using an assessment tool that specifies their intensity and nature. Our primary objective was to explore subjective perceptions of cognitive functioning in COVID-19-associated with brain fog using a tool that was previously validated for assessing subjective cognitive complaints. A total of 68 participants were recruited and the Subjective Scale to Investigate Cognition (SSTICS) was used to assess cognitive complaints. This was the first time that the SSTICS was used for this purpose in subjects with COVID-19. In addition, participants were administered a questionnaire assessing for the presence of various symptoms, as well as COVID-19 clinical parameters. The neuropsychological basis for the construct of the SSTICS was related to the cognitive complaints expressed by participants. A reliability analysis of our sample indicated a high degree of internal consistency (Cronbach’s alpha= 0.951). Associations between various SSTICS scores and COVID-related symptomatology and the differences between group of participants who reported cognitive complaints (“complainers”) and those who did not were assessed. We performed an exploratory factorial analysis based on Principal Component Analysis (PCA). Based on their distribution, participants were grouped into: “good functioning” - scores 0-9 (35.3%); “medium functioning” - scores 14-23 (25%); and “poor functioning” - scores 26-71 (39.7%). The mean SSTICS score was 20.59 (SD 16.61) and correlated with the quarantine duration and loss of smell. Complainers differed significantly from non-complainers in the total number of symptoms, the quarantine duration and the presence/absence of specific symptoms, such as loss of smell, tiredness and aches/pains. Our study showed that >10% of patients reported subjective cognitive complaints following COVID-19, with most reporting mild or serious cognitive complaints, mostly within the domains of memory, attention, language, executive functioning or praxis.

Soil biological health assessment based on nematode communities under maize and peanut intercropping

BackgroundCereal/legume intercropping can enhance crop productivity and improve soil health in dryland farming. However, little is known about soil biological health under maize/peanut intercropping. The aim of this study was to assess soil biological health based on nematode communities in a maize/peanut intercropping system.MethodsWe conducted a field experiment with different planting patterns, including monoculture maize (M), monoculture peanut (P), and maize intercropped with peanut (IM, intercropped maize; IP, intercropped peanut) to determine the influence on soil biological health. We measured soil physicochemical properties and nematode communities, and employed exploratory factor analysis combined with cumulative normal distribution curve scoring to identify potential soil biological health traits.ResultsThe intercropped maize gave the highest plant parasitic nematode abundance, trophic diversity index, evenness index, and structure index. The monoculture peanut gave the highest enrichment index and least plant parasitic nematode abundance, trophic diversity index, Shannon diversity index, evenness index, structure index, and channel index. We identified four soil biological health traits, including basic nutrients and biodiversity, food web complexity, slow energy channel, and fast energy channel, mainly represented by soil ammonium nitrogen and Shannon diversity index, structural index and omnivore-predator nematode abundance, fungivorous nematode abundance and plant parasitic nematode abundance, microbial biomass carbon and bacterivorous nematode abundance, respectively. The intercropping systems improved the comprehensive score of soil biological health, especially maize intercropping soil. Intercropping maize and intercropping peanut significantly improved oil biological health traits representing the food web complexity compared with the corresponding monoculture soils.ConclusionsOur results indicate that soil nematode and physicochemical indicators reflect different soil biological health traits. Among those traits, the improvement of basic nutrients and biodiversity and the complexity of the food web were the main reasons for improving soil biological health through the intercropping system.

Unveiling the intersection of technology and pedagogy: a domain-specific exploration for developing religious moderation content with an exploratory and Rasch Perspective

ABSTRACT The primary aim of this study was to investigate the construct validity of a survey focussing on the use of technology and teaching techniques to promote religious moderation, employing exploratory factor analysis (EFA). A total of 116 educators, who teach character development courses, were recruited to participate in the study. The developed instrument is based on the Technology Pedagogical Content Knowledge (TPACK) framework and has been validated through expert and cognitive interviews with religious education lecturers. The study’s results demonstrate that participants were able to discern conceptual distinctions between TPACK domains. Four factors were identified: TPACK, Pedagogical Content Knowledge (PCK), Technological Knowledge (TK), and Pedagogical Knowledge (PK). TPACK encompasses both Technological Pedagogical Knowledge (TPK) and Technological Content Knowledge (TCK), while PCK includes Content Knowledge (CK). Additionally, Rasch statistical analysis was employed to determine that the instrument measures a single latent variable, namely religiously moderated TPACK, with high reliability based on the fit of the scale to the Rasch model. The statistical data from the EFA and Rasch analyses suggest that this survey can serve as a valuable tool for researchers and educators interested in exploring TPACK within the context of religious moderation.

Design and psychometrics of a tool for measuring social cognitive factors related to the preventive behaviors toward Covid-19 in the society

With the emergence of new strains of Covid-19, the adoption of preventive behaviors is still considered a requirement to control this disease. Therefore, considering the importance of social cognitive factors in adopting various types of preventive behaviors, the present study was conducted to design and psychometrically measure the social cognitive factors related to Covid-19 preventive behaviors. A cross-sectional study was conducted on 526 people ages 18 and over with multi-stage stratified, cluster and random sampling in Isfahan, Iran in 2022. The questionnaire was validated and formulated in three stages: designing, creating and reducing items. After collecting information and creating a bank of items, qualitative and quantitative methods were used to calculate the tool’s validity. Data analysis was done in SPSS23 software at a significance level of less than 0.05. In the present study, the average age score of the participants was 39.16 ± 11.48. The results related to the construct validity in the exploratory part show that the five factors (Outcome expectations, self-efficacy, social support, self-regulation and barrier self-efficacy) obtained have a specific value higher than one and range from 1.376 to 9.343. Correlation between factors shows that all factors have a relatively high relationship with each other (P < 0.05). According to the exploratory factor analysis, the final questionnaire contains 29 items and 5 constructs from socio-cognitive theory. The results showed that the thematically and technically designed tool has been prepared in an appropriate way for each of the structures and can accurately measure the structures of outcome expectations, self-efficacy, social support, self-regulation and barrier self-efficacy to explain the preventive behaviors of Covid-19 to evaluate.
