Structural equation model of the influence of noise annoyance on miners’ unsafe behavior in coal mines

Miners' unsafe behavior (UB) is the main cause of coal mine accidents. Previous research has suggested that excessive noise in tunnels impacts miners' temperaments and safe production behavior. To explore the influence of noise on UB, four different dimensions of noise annoyance were identified: cognitive, emotional, communication, and physical mechanism annoyance. The coal mine noise annoyance scale, miners' unsafe behavior intention (UBI) scale, and miners’ UB scale were developed according to different dimensions. In the first survey, a total of 200 questionnaires were distributed in the two coal mines, and 193 valid questionnaires were recovered. Exploratory factor analysis was conducted, and invalid items were removed according to the analysis results to form the final scale. Then, 500 final scales were distributed in two Chinese coal mines, and 482 valid questionnaires were collected. Confirmatory factor analysis was conducted by collating the data of the second questionnaire. Based upon the structural equation model (SEM), the SEM of the influence of noise annoyance degree on UB and the path analysis with latent variable path analysis with the latent variables (PA-LVs) mediating model of the effect of UBI on UB were established, and the path coefficients with fitting data of the model were analyzed. The results indicated that the four dimensions of coal mine noise annoyance had a strong positive impact on UB, which was reduced by less noise annoyance. In addition, the Bootstrap method was used to verify the mediating method among the four dimensions of noise annoyance, cognitive annoyance, emotional annoyance, with communication annoyance indirectly affecting UB through UBI. The research results provide theoretical support for reducing the UB of miners and improving coal mine safety levels.

The Validity and Reliability of the Online Cooperative Learning Attitude Scales in the Indonesian Language

Interactive online learning requires students’ cooperation. Online cooperative learning focuses on learning activities on group cohesiveness to achieve the highest cognitive level. Students can improve their teamwork skills, problem-solving skills, social skills, self-confidence, academic success, and metacognition levels through online cooperative learning activities. The Online Cooperative Learning Attitude Scales (OCLAS) scale is a tool to measure students’ attitudes towards online cooperative learning. Education in Indonesia uses Indonesian as the language of instruction. Therefore, the adaptation of measurement tools such as OCLAS into the Indonesian language is crucial. This study aimed to adapt OCLAS into Indonesian by translating the original OCLAS into the Indonesian language and determining the instrument’s validity and reliability. The OCLAS has three main components: positive interdependence, individual accountability, and group processing for equal individual contribution. The original version contained 17 statements with responses using a Likert scale of five and seven points. We validated the OCLAS using the item-correlation method. The reliability was measured using the Cronbach’s Alpha method, which is useful for measuring internal consistency. The original OCLAS was translated into the Indonesian Language. A language center in a prominent university performed the verification of forward and backward translation of the Indonesian OCLAS. The Indonesian-OCLA was distributed to 59 students at a private university from the pharmacy and non-pharmacy study programs and 275 high school students. The validation results showed seven invalid items for pharmacy students, five invalid items for non-pharmacy students, and six invalid items for high school students. The Indonesian-OCLAS has Cronbach’s Alpha reliability with a value of 0.711 for pharmacy students, 0.791 for non-pharmaceutical students, and 0.702 for high school students. This study showed that ten out of 17 statements had good validity, and they were reliable. Therefore, we recommended the usage of the Indonesian-OCLAS toward high school and college students.

Factors affecting school performance: Does a mixed curriculum make a difference?

This article reports on a study that attempts to fill the gap of research focusing on school performance measurements, especially those which involve curriculum types. It established the factors that measured school performance using Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) and analyzed any differences in the performance of schools adopting national curriculum and those adopting mixed curriculum in Greater Jakarta. From 29 items, eight invalid items were dropped, and the EFA identified eight factors, which were categorized into social-emotional learning, school participation, relationship, physical-mental health, physical safety, emotional safety, academic growth, and discipline. Then, the scale was validated using data collected from 684 secondary students using CFA. Chi-square goodness-of-fit test was not statistically significant. However, other indices such as Incremental Fit Index, Comparative Fit Index, Tucker-Lewis Index, Root Mean Squared Error of Approximation, and Standardized Root Mean Square Residual were within acceptable limits, indicating that the eight EFA factors had been validated. Moreover, this study found that schools with mixed curricula had higher performance than those with a national curriculum. Nevertheless, it cannot be generalized because the linear regression shows that the p-value was higher than 0.05 (0.164).

Psychometric properties and diagnostic criteria of Scale for the assessment of negative symptoms (SANS) in schizophrenia

The Scale for the assessment of negative symptoms (SANS) is one of the most widely used clinical assessment tools for negative symptoms.Thepurposeof this study was psychometric analysis and modification of the SANS with the definition of criteria for assessing the severity of negative symptoms in the dynamics of therapy in patients with schizophrenia.Materialandmethods:The study involved 157 patients with a diagnosis of schizophrenia, the age range of participants ranged from 18 to 59 years. Psychometric analysis was done on the base of the Rush measurement with the definition of criteria for assessing the severity of negative symptoms based on the index of minimum detectable changes for 95% probability (Minimum detectable change95%— MDC95%).Results:Five SANS diagnostic items with low construct validity were identified. The technique was modified by excluding these invalid items. SANS was modified by eliminating of 5 invalid items. The modified version of SANS demonstrated high reliability (reliability index = 0.97) and discriminativeness (the ability to differentiate 12 metric levels of severity of negative symptoms). Factor analysis revealed the heterogeneity of the metric structure of the technique: points in the first group reflect the impoverishment of speech and emotional manifestations, points in the second group reflect the decrease of the patient’s involvement in various activities and restriction of social interaction. Thus, the two-dimensional structure of the SANS scale (“expression” factor and “motivation” factor) is fully consistent with the modern concept of negative symptoms, which allows to consider the total SANS score as an indicator of the severity of the negative syndrome construct. In the course of the metric analysis, the criteria for assessing the severity of negative symptoms in the dynamics of the therapy were determined.Conclusion:The modified version of SANS has adequate psychometric characteristics. The diagnostic criteria are suitable for use in clinical practice and research.
