Efficacy of Latino-based multimedia to prevent occupational hearing loss

Occupational hearing loss is a risk among the 1.4 million Latino construction workers in the U.S. The purpose of this study was to develop and test a culturally and linguistically appropriate intervention to prevent occupational hearing loss. The researchers developed a computer-based educational program using Pender's Health Promotion Model. Formative research led to revisions in the questionnaire response formats and user-computer interface. Construction workers (n=145; 107 Latino, 38 non-Latino) were recruited through their unions to participate in the bilingual (Spanish/English) computer-based intervention and complete a post-intervention survey. Process evaluation indicated acceptability of the intervention. Over 90% of participants agreed that the program kept their interest, was an effective way to learn about hearing protection, and that the language was not complicated. Most (87%) agreed that the program was fun, and that the length (79%) and pace (70%) of the program were just right. Significantly more Latinos said the program was fun (90% vs. 60%), was not too long (93% vs. 54%) and not too slow (88% vs. 27%). Preliminary analyses of time 1 data indicated that an intermediate outcome, intention to use hearing protection, increased significantly post-intervention (p<.001). Final outcomes and model factors related to use of hearing protection at time 2 will be reported. The more favorable response of Latinos may reflect the successful targeting of the intervention to this population. If effective, this intervention can be disseminated by electronic means to promote the hearing health of Latino construction workers.
