Physical work characteristics, Psychosocial work characteristics, Musculoskeletal discomforts, Electronic workers


Work-related musculoskeletal discomfort is a significant occupational health problem for workers in an electronics factory. This is a correlational descriptive study of physical work characteristics, psychosocial work characteristics and musculoskeletal discomforts among 378 workers in an electronics factory. The study instrument was self-administrative and consisted of four parts: 1) personal and working information, 2) physical work characteristics, 3) psychosocial work characteristics, and 4) musculoskeletal discomforts. The study instrument was reviewed by experts and gained the content validity index of 1.0. Three parts of the instrument: physical work characteristics, psychosocial work characteristics, and musculoskeletal discomforts, were tested for reliability and yielded acceptable values of 0.93, 0.84 and 0.86, respectively.  Data were analyzed using descriptive statistics, chi-square test and biserial correlation coefficient.  

The results showed that he relationship between physical work characteristics and musculoskeletal discomforts was statistically related (x2=12.85, 4.66, p < .05). Regarding to psychosocial characteristics, the job demands was statistically significant related to musculoskeletal discomforts prior to seven days and twelve months of the study (r = 0.12 and 0.15 at < .05, respectively). 

 These results suggest that physical and psychosocial work characteristics are important factors associated to musculoskeletal discomforts in workers in an electronics factory. These two types of working characteristics should be improved upon in order to enhance these workers’ health.
