Abstract
Aims: Neck pain is a common problem among teachers. This study aimed to design and evaluate an instrument for measuring occupational neck pain preventive behaviors among teachers.

Method and Materials: This study was conducted from August to December 2020 among high school teachers in Tehran, Iran. In the qualitative phase, a purposeful sample of teachers (30 participants) was interviewed to generate an item pool. The content and face validity were performed, and an initial questionnaire was sent to 25 teachers of the target community to be examined in terms of simplicity, importance, relevance, and clarity. Then, a cross-sectional study with 146 teachers with a mean age of 36.7 ± 8.92 years was conducted, by which exploratory factor analysis was done to obtain the factor structure of the questionnaire. Internal consistency (Cronbach's alpha) was calculated to assess reliability, and the Intra Class Correlation Coefficient (ICC) to assess stability.

Findings: Based on analysis of the exploratory factor, 8 factors with 43 substances, that together accounted for 65,25% variance, were obtained. The correlation matrix in the case scale to establish the validity of the questionnaire showed satisfactory results. The results of face validity showed that 4 factors were not approved and were removed from the questionnaire. Reliability evaluation with the internal consistency method (Cronbach's alpha) showed excellent compatibility (0.87). The ICC reliability assessment showed that the questionnaire has satisfactory stability (0.92).

Conclusion: This instrument could be applied to evaluate unhealthy behavior due to neck pain and so improve these risky behaviors.
