Industrial workers and bullying: a systematic review and meta-analysis of workplace violence.

Workplace violence is a significant problem in industry, especially among rank-and-file workers, known as "blue-collar workers". This systematic review and meta-analysis aim to evaluate the suitability of the reduced Negative Acts Questionnaire (NAQ-R) as an instrument to measure workplace violence in this type of population and synthesize the results of studies that have used it in different industrial sectors. A systematic review was conducted in accordance with the PRISMA 2020 statement. Publications describing populations of industrial workers were identified and included in the meta-analysis. For meta-analysis, we extracted data that allowed us to estimate the effect size of the included studies. We used a random-effects model to estimate the overall effect size and assessed heterogeneity between studies using the I² statistic. The global effect size test showed that the overall effect size was significantly different from zero (3.00, t=22.28, p<0.001), indicating an overall effect in relation to workplace violence measured by the NAQ-R in industrial workers. Our results support the claim that the NAQ-R is an effective tool for assessing workplace violence among industrial workers. These findings have important implications for practitioners and researchers working in the field of industrial psychology and occupational health.

Prevalence of suicidal behavior in a northeastern Mexican border population during the COVID-19 pandemic.

Introduction: Before the pandemic, suicide was already considered a global public health problem. The outbreak of COVID-19, a coronavirus-related infectious disease, began to impact people's physical and mental health. The factors that either contribute to or mitigate this risk need to be better understood, and this can only be accomplished through research. Therefore, this study aimed to study the prevalence of suicidal ideation and behavior in Tamaulipas, Mexico, during the COVID-19 pandemic. Methods: A quantitative, descriptive, and cross-sectional study was conducted. The sample consisted of 659 participants, of whom 194 (29.5%) were men and 465 (70.5%) participants were oldwomen, ranging in age between 16 and 68 years (M = 22.56, SD = 7.26). An adapted version of the Spanish version of the Columbia Suicidal Severity Rating Scale was used to assess the seriousness of suicidal ideation and behavior. Results: The higher rates of suicidal indicators were suicidal ideation with "wish to dead" (39.9%), while the lower was suicidal ideation with a specific plan (8.2%). A total of 18.2% of participants reported "suicidal attempts before COVID-19," of whom 40% reported "suicidal attempts in the last 3 months." Suicidal behavior rates were lower: 13.7% of participants reported "non-specific preparatory behavior" and 13.3% reported "actual suicide attempts." Women were more likely than men to exhibit almost all indicators of suicidal ideation and behavior (OR = 1.63-2.54; 95% CI = 1.11-2.41, 1.76-3.68), as well as confinement (OR = 2.60; 95% CI = 1.73-3.91). Confinement for more than 40 days (OR = 0.55-0.66; 95% CI = 0.40-0.75, 0.47-0.93) and knowing a person infected with COVID-19 (OR = 1.57-2.01; 95% CI = 1.02-2.42, 1.20-3.34) were associated with a higher risk of exhibiting several suicidal indicators and having previously attempted suicide. Conclusion: Being a woman, knowing a person infected with COVID-19, and being confined, especially for longer than 40 days, are all risk factors for suicidal ideation. Therefore, intervention programs are needed to reduce the suicide risk prevalence, especially these days because of the influence of the pandemic, and should be primarily focused on those who present the risk factors associated with suicidal behavior identified in this study.

Unemployment and mental health in a community population from a border city in Mexico.

BACKGROUND: The constant changes in the global economy generate instability in the markets, favoring the closing of companies, dismissals of personnel, job losses. Unemployment has been associated with adverse psychological effects, serving as a predictor of poor mental health. OBJECTIVE: The main goal was to analyze the relation between work status and mental health. METHODS: A cross-sectional, quantitative study was carried out with a sample of community population, inhabitants of the urban area of a Mexican city. The sample consisted of 1351 participants, being 577 men (43%) and 774 women (57%) with an average age of 41.46 (SD = 17.00). The participants were selected by a quota sampling, in 13 representative points of Matamoros' city urban area. Home surveys were applied; the Spanish version of the Symptom Checklist 90 (SCL-90) was used for mental health assessment. RESULTS: The model explaining the relation between work status and mental health (GFI) was significant (p < 0.01). Unemployment was related to higher scores in all sub-scales of psychopathologies evaluated by the SCL-90, in comparison with the rest of work status categories. CONCLUSIONS: The unemployed, followed by housewives, presented indicators of poorer mental health, while the retired and those in strikes or lockouts showed the best mental health indexes.

Traffic Noise Annoyance in the Population of North Mexico: Case Study on the Daytime Period in the City of Matamoros.

Aim: The presence of noise in urban environments is rarely considered a factor that causes damage to the environment. The primary generating source is transportation means, with vehicles being the ones that affect cities the most. Traffic noise has a particular influence on the quality of life of those who are exposed to it and can cause health alterations ranging from annoyance to cardiovascular diseases. This study aims to describe the relationship between the traffic noise level and the perceived annoyance in the inhabitants of a city on the Northern Border of Mexico. The work carried out in a city represents the vulnerability characteristics: economic, social, and migratory of its sizable portion of the inhabitants. Due to that, it is impossible to identify precisely the number of residents as the number of vehicles in circulation. Methods: The streets and avenues with an annual average daily traffic of more than 1,000 vehicles were considered for the measurement of traffic noise. The equipment used was a vehicle gauge with non-invasive speed radar; type I integrating sound level meters, with their respective gauges and tripods. A questionnaire was applied to people living within 250 m of the streets and avenues in which the noise was measured. Results: The noise measurement found a parameter of LAeq estimated for 12 h during the day, exceeding 70 dBA. The data received from the questionnaire were statistically tested by using Pearson's correlation tests. A total number of 2,350 people were participated, of whom 1,378 were women (58.6%) and 972 were men (41.4%). The age of participants is ranged from 18 to 75 years. The overall perception of traffic noise annoyance identified that 1,131 participants (48.1%) responded "Yes" as they considered the noise annoying. Participants who responded "No" as well as those who responded "Do not know" resulted in a total of 1,219 people (51.9%). Conclusion: The results show that the population is desensitized to traffic noise and does not perceive it as an annoyance. The flow of vehicles and the type of vehicles are the significant factors for the propagation and increase in the traffic noise levels. Women present a considerable appreciation of traffic noise perception instead of younger people who demonstrate a higher tolerance to high-level exposure. This reflects the lack of information of the population around the noise problem and its effects.

Road risk behaviors: Pedestrian experiences.

Objective: The objective of this study was to identify pedestrian risk behaviors that result in traffic accidents and characterization of the accidents experienced by participants in this study to provide information for the generation of integral preventive strategies. Methods: The study was correlational, descriptive, and transversal and followed a quantitative approach divided into 2 stages. In the first stage, an observational study was performed to identify the manifested risk behaviors of pedestrians, which served as a basis for the construction and design of a questionnaire. In the second stage, the questionnaire was applied to a group of 1,536 participants. Pearson's correlation coefficient was applied to establish associations between gender and age with respect to risk behaviors. Results: The 3 behaviors that participants reported performing always or very often include using electronic gadgets (except mobile phones), not using a pedestrian crosswalk, and using a mobile phone. In addition, 18.5% were involved in at least one road accident as a pedestrian in the last 5 years. Of the total number of registered accidents, 21% resulted in pedestrian injuries, 48.3% of which were serious. These were due to external causes not related to human factors or unidentified (58.5%) and behavior factors as a whole (41.4%, 31.5% of which were caused by pedestrians). Pearson's correlation coefficient showed evidence of a correlation between age and risk behaviors. Conclusions: All subjects in this study performed several risky actions as pedestrians, at least occasionally, and at least one fifth had been involved in a road accident as a pedestrian. It is known that the surroundings can positively or negatively influence individuals' behaviors; therefore, once prevention measures are identified, it is possible to influence risk behaviors. Therefore, road safety education and the physical environment must be considered together, and efforts focused on optimum infrastructure also need to consider road safety education.

DIF in the Spanish Version of the Verbal Selective Reminding Test Using Samples From Hispanics in the United States, Mexicans, and Spaniards.

AIM: Before a test can be used in the target population, it is necessary to demonstrate that there is measurement equivalence. One way to do this is by studying differential item functioning (DIF). OBJECTIVE: In this study, we used the Mantel-Haenszel procedure and logistic regression to analyze DIF in the Spanish version of the Verbal Selective Reminding Test between Spaniards, Mexicans, and Hispanics in the United States. METHOD: Three balanced samples, matched by age, education, and sex, were studied: Spaniards, Mexicans, and Hispanics [616 healthy participants from Spain (n = 211), Mexico (n = 201), and the United States (n = 205)]. A six-trial version of the Spanish version of the Verbal Selective Reminding Test was administered and scored according to standard procedures. RESULTS: Statistical analysis showed some DIF between the samples of Spaniards, Mexicans, and Hispanics. A bootstrap validation of results confirmed that the item pollo showed DIF: the Mexicans and Hispanics outperformed the Spaniards, holding a total score constant. The item oído also showed DIF and was remembered in greater measure by the Spaniards. CONCLUSION: The Spanish version of the Verbal Selective Reminding Test can be used with Hispanic populations.

Uso problemático de internet, cyberbullying y ciber-violencia de pareja en jóvenes universitarios

Resumen Las Tecnologías de la Información y Comunicación se han desarrollado con rapidez integrándose en la vida cotidiana de los adolescentes y los jóvenes. Por ello, esta investigación con diseño no-experimental y transversal analizó las diferencias por sexo en el uso problemático del internet, el cyberbullying y la ciber-violencia de pareja; así como la posible relación entre las variables mencionadas. La muestra fue conformada por 456 estudiantes, procedentes de dos universidades mexicanas, con edades entre 17 y 30 años (M = 19,86; DT = 2,12). Los resultados mostraron pocas diferencias entre hombres y mujeres; asimismo se presentaron correlaciones bajas positivas entre la mayoría de los indicadores de uso problemático de internet con ciberbullying; el uso problemático de internet y ciber-violencia de pareja; y entre ciberbullying y ciber-violencia de pareja. Se concluyó que las conductas violentas de jóvenes mediante nuevas tecnologías parecen generalizarse a las relaciones entre pares y de pareja. Se discuten los resultados destacando la necesidad de más estudios sobre estos fenómenos cada vez más presentes en jóvenes.

Abstract The Information and Communication Technologies have developed at a fast pace, integrating themselves in the daily life of adolescents and young people. For this reason, this non-experimental cross-sectional study analyzed the gender differences in problematic Internet use, cyberbullying and cyber-violence, as well as the possible relationship between these variables. The sample consisted of 456 students, from two Mexican universities, aged between 17 and 30 years (M = 19,86; DT = 2,12). The results showed few significant differences between men and women; likewise, significant positive correlations were found between most of indicators of problematic Internet use with cyberbullying; between problematic Internet use and cyber dating violence; and between cyberbullying and cyber dating violence. It was concluded that violent behavior of young people through new technologies seems to be generalized to relationships with peers and couples. It was discussed the results highlighting the need for more studies on these phenomena increasingly present in young people.

Conocimiento y actitud en prevención de trabajadores lesionados de una empresa metalmecánica en México / Knowledge and attitudes towards prevention among occupationally injured workers at a Mexican metal-mechanic company

Se investigan a 51 trabajadores que sufrieron algún tipo de accidentes de trabajo durante el año de 2007, en una empresa metalmecánica, no importando la región anatómica de la lesión con la finalidad de determinar el nivel de conocimiento y actitud en prevención de riesgos laborales que existe entre ellos. Tal información servirá para mejorar la administración de la seguridad en la empresa. La investigación es de tipo no experimental, descriptiva y transversal. Para la recolección de datos se utilizó, un cuestionario integrado por 30 ítems, divididos en tres apartados: datos demográficos y las variables: conocimiento y actitud en prevención de riesgos laborales. La validez del instrumento obtuvo un valor de alfa de Cronbach del 0,74. Con respecto a las variables de estudio, los resultados obtenidos nos indican que, los trabajadores presentan un nivel bajo de conocimiento en prevención de riesgos laborales. En relación con la variable actitud, estos se ubicaron en un nivel bajo también. Por lo que se concluye que, el conocimiento en prevención de riesgos laborales y la actitud de los trabajadores, están directamente relacionados

51 workers that suffered some type of work accident were investigated during 2007, at a metal-mechanic company; the lesion’s anatomic region is not an issue, in order to determine the knowledge and attitude level on occupational risks prevention. Such information will enhance safety management at the company. The investigation is descriptive, transverse and non-experimental. For data collection was used a questionnaire of 30 multiple-choice, divided into three sections: demographics data, and the variables knowledge and attitude on occupational risk prevention. The validity of the instrument got a Cronbach´s alpha of 0,74. With respect to the variables, the results indicate that workers have a low level in prevention knowledge occupational risk. Regarding the attitude variable, these were located at a low level also. As it is concluded that knowledge on occupational risk prevention and the attitude of workers are directly related
