Ensuring Accuracy: Calculating the Content Validity Index for Teacher Job Satisfaction Surveys among Henan private universities in China

This study assesses teacher job satisfaction in private universities in Henan, China, using the Content Validity Index (CVI) to ensure the precision of questionnaires. To establish content validity, a panel of five experts was assembled. The research examined critical factors of teacher job satisfaction: salary, promotion, supervision, benefits, potential rewards, operational procedures, colleagues, nature of work, and communication. These elements were evaluated using both the scale-level CVI (S-CVI) and item-level CVI (I-CVI) on a 4-point relevance rating scale, known for its reliability. Items scoring below an I-CVI of 1.00 or an S-CVI of 0.9 were removed. The results indicate strong content validity, validating the tool’s effectiveness for measuring teacher job satisfaction in Henan’s private universities. Future studies should examine the construct validity and reliability of this scale. These findings underscore the scale's utility for researchers examining teacher job satisfaction in comparable educational environments.
