Questionnaires selecting translating and validating
Factor analysis identified two principal components that jointly accounted for 65.9% of the variance.In general, the Iranian version of the SF-36 performed well and the findings suggest that it is a reliable and valid measure of health related quality of life among the general population.For instance, speech recognition has proven useful to technologies involving vehicles (e.g., in-car speech recognition systems), technologies involving health care, technologies involving the military and/or law enforcement, technologies involving telephony, and technologies that assist people with disabilities.Speech recognition systems are often trained and deployed to end-users.The survey questionnaire can be rapidly deployed and completed by the respondents, especially if there’s an incentive that is given after their participation.Traditional survey methods often require you to spend thousands of dollars to achieve the optimal results.The mean age of the respondents was 35.1 (SD=16.0) years, 52% were female, mostly married (58%) and the mean years of their formal education was 10.0 (SD=4.5).Reliability was estimated using the internal consistency and validity was assessed using known groups comparison and convergent validity. The internal consistency (to test reliability) showed that all eight SF-36 scales met the minimum reliability standard, the Cronbach’s α coefficients ranging from 0.77 to 0.90 with the exception of the vitality scale (α=0.65).
However, one should consider the drawbacks and disadvantages of an online survey method. The Internet is a vast virtual world that connects all kinds of people from around the globe.
