Comparison of the original and revised structures of the Health Promotion Model in predicting construction workers' use of hearing protection.

Pender's health promotion model (HPM) has been revised, including substantial changes in its structure. The purpose of this study was to compare the fit and predictive usefulness of the original and revised structures of the HPM as applied to the use of hearing protection devices by 703 construction workers. Structural equation modeling was used to evaluate the two alternative forms of the model. Both forms of the model fit well, with the revised structure having a better fit and explaining more of the variance in use of hearing protection (28% vs. 18%). Results support the revised structure of the health promotion model (HPM) over the original form, and indicate it may be useful in understanding and predicting use of hearing protection.

Efficacy of a computer-based hearing test and tailored hearing protection intervention.

Advances in computer technology and accessibility enable researchers to provide individually tailored interventions for behavioral change. Using multimedia technology, this study developed and tested a computer-based hearing test and a tailored intervention. The purpose of this study was to evaluate, using a randomized experimental design, the efficacy of the intervention to increase workers' use of hearing protection. The tailored intervention developed by the research team showed more significant short-term effect measured immediately after the intervention than the control intervention. For the long-term effect measured 1 year after the intervention, both tailored and control groups showed significant increase in their reported use (7% vs. 6%) from preintervention to postintervention, but no significant difference between the two groups. The change accomplished in this study was small progress toward the desired level of 100% use of hearing protection to prevent noise-induced hearing loss. This finding showed that changing workers' hearing protection behavior is difficult.

Predictors of hearing protection use for Hispanic and non-Hispanic White factory workers.

The 2000 United States Census reported significant growth in the number of Hispanic workers. The National Institute for Occupational Safety and Health (NIOSH, 1996) has identified noise-induced hearing loss as a significant occupational threat. Current theoretical models need to be evaluated for their utility with Hispanic workers. The Predictors for Use of Hearing Protection Model (PUHPM) is a framework for increasing workers' use of hearing protection devices (HPDs). Using regression analysis, the explained variance in HPD use by the model predictors was examined in a sample of 208 Hispanic factory workers. Explained variance was lower for Hispanics (R2 = .20) than for non-Hispanic Whites (R2 = .37). Further research with Hispanic workers is needed to improve the PUHPM fit.

Hearing loss among operating engineers in American construction industry.

OBJECTIVE: Occupational noise exposure and noise-induced hearing loss (NIHL) among construction workers has long been recognized as a problem in the United States, yet little is known about the prevalence of NIHL among American construction workers. The purpose of this study was to determine the prevalence and characteristics of hearing loss among operating engineers (OEs) who operate heavy construction machinery. METHOD: As a part of hearing protection intervention, an audiometric test was conducted for both ears at frequencies 0.5 through 8 kHz in the soundproof booth. Prior to the audiometric test, a paper-pencil pre-hearing test questionnaire was administered and an otoscopic examination was completed. Prevalence of hearing loss was determined based on hearing threshold levels (HTLs) in the worst ear with a low fence of 25 dB. RESULT: A total of 623 workers were included in the analysis and they were predominantly middle-aged Caucasian males (mean age = 43 years, Caucasian = 90%, male = 92%). Over 60% of OEs showed hearing loss in the noise-sensitive higher frequencies of 4 and 6 kHz. The rate of hearing loss was particularly higher among workers who reported longer years of working in the construction industry. Workers showed significantly poorer hearing in the left ear, and a typical characteristic of NIHL, a V-notch at 4 or 6 kHz, was not shown in this population. Thirty-eight percent reported ringing/buzzing in the ear and 62% indicated having problems in understanding what people say in loud noise. Average reported use of hearing protection devices (HPDs) was 48% of the time they were required to be used. Significant inverse relationship was found between higher frequency (4-6 kHz) hearing loss and use of HPDs (r =-0.134, p < 0.001). Workers using HPDs more had significantly better hearing than those who did not. CONCLUSION: The study demonstrated a significant NIHL problem and low use of HPDs in OEs. An effective hearing conservation program, including a periodic audiometric testing and hearing protection intervention, for this study population should be in place.

Audiometric testing and hearing protection training through multimedia technology.

The purpose of this paper is to present the development process of a computer-based audiometric testing and tailored intervention program, and assess its feasibility by obtaining users' feedback. The program was implemented for 397 operating engineers at their union training center, and its feasibility was evaluated by obtaining quantitative and qualitative feedback from the participants through a survey and focus group. Over 96% of the participants indicated they liked receiving a hearing test by computer; the computer-based test worked smoothly; and the computer-based training was well organized, effective and held their interests. Almost all (more than 99%) said they would recommend this program to other workers. This project is considered as one of the first ones incorporating multimedia computer technology with self-administered audiometric testing and tailored training. Participants' favorable feedback strongly supported the continued utilization of this approach for designing and developing health screening and intervention to promote healthy behaviors.

Ethnic differences in predictors of hearing protection behavior between Black and White workers.

The purpose of the study is to determine whether there are ethnic differences in predictors of hearing protection behavior between Black and White workers. The Predictors of Use of Hearing Protection Model (PUHPM) derived from Pender's Health Promotion Model (Pender, 1987) was used as a conceptual model. A total of 2,119 (297 Blacks, 1,822 Whites) were included in the analysis. Internal consistency of instrument items was assessed using theta reliability estimates. Significant predictors of the use of hearing protective devices (HPDs) for Black and White workers and differences in predictors between the two groups were examined using multiple regression with interaction terms. Ethnic differences in scale or individual item scores were assessed using chi-square and t-test analyses. Different factors influenced hearing protection behavior among Black and White workers. The model was much less predictive of Blacks' hearing protection behavior than Whites' (R2 = .12 vs. .36). Since the PUHPM was not as effective in predicting hearing protection behavior for Blacks as for Whites, future studies are needed to expand the PUHPM through qualitative study and to develop culturally appropriate models to identify factors that better predict hearing protection behavior as a basis for developing effective interventions.

Workplace violence against K-12 teachers: implementation of preventive programs.

Decreasing both workplace and school violence needs to be a priority of individuals, families, communities, and workplaces for the effort to be successful. Key factors associated with school and workplace violence such as parental influences, school staff and police involvement, peer pressure, student influences such as drug and alcohol abuse and a preoccupation with weapons, and the mass media have all been identified as possible factors associated with violence against teachers. In addition, individual student characteristics such as gender, socioeconomic status, and a history of prior violence may play a role. However, none of these factors can be identified or singled out as the reason for violence. Violence against teachers occurs as a result of a combination of these factors. Understanding how these factors interact should be a goal of every community and school. Occupational health nurses have the unique opportunity to partner with communities, school nurses, and the school system to develop effective violence prevention programs. Working in schools is an area of expansion for occupational health nurses. They have the expertise to perform worksite assessments and to identify key areas of weakness throughout the facility. Their expertise in reviewing and analyzing workplace injury data and developing cost effectiveness analysis for proposed interventions is unique. Occupational health nurses also have the skills to network with school officials and other key stakeholders to develop interventions to impact the substantial implications of violence in the schools.

Occupational health nursing practice, education, and research in Korea. An international update.

1. In Korea, occupational health nurses have been working as health managers at the workplace and as part of a hospital based group occupational health service since 1991. The role of occupational health manager, required by law, includes providing preventive and primary care, safety management, and inspection of the work environment. 2. Recently, occupational health nursing practice-based lecture has increased, and more emphasis has been placed on the process of occupational health nursing in both undergraduate and graduate programs. 3. The Korean Association of Occupational Health Nurses and the Korean Academic Society of Occupational Health Nursing have been working to develop professional competence for occupational health nurses since 1991. 4. Until the mid 1990s, occupational health nursing research focused primarily on role and job satisfaction of occupational health nurses. However, the number of research studies has dramatically increased and, gradually, survey studies have been replaced by studies with experimental design.

Effectiveness of a tailored intervention to increase factory workers' use of hearing protection.

BACKGROUND: In the United States it is estimated that more than 30 million workers are exposed to harmful levels of noise on the job. When engineering or administrative controls cannot be used to reduce noise, workers should always use hearing protection devices (HPDs) when exposed to loud noise to prevent noise-induced hearing loss (NIHL). Previous research has shown that workers do not always use HPDs when required; therefore, it is essential that workers assume personal responsibility for preventing NIHL by increasing their use of HPDs. OBJECTIVES: This study tested the effectiveness of an individually tailored multimedia intervention to increase use of HPDs by factory workers. METHODS: A randomized controlled design was used to compare the effects of a tailored intervention (n= 446) with two other interventions (a nontailored predictor-based intervention (n= 447) and a control intervention (n= 432)) on workers' self-reported use of HPDs 6 to 18 months following the intervention. RESULTS: Only those workers receiving the tailored intervention significantly increased their use of HPDs from pretest to posttest. However, this increase significantly differed from the nontailored group but not from the control group. CONCLUSIONS: Individually-tailored interventions offer promise for changing behavior. In light of the similarity between the results for the tailored intervention and the control intervention groups, further research is needed to understand barriers to HPD use and how to maximize the benefits of individually tailored interventions in this setting.
