روایی و پایایی نسخه فارسی نمایه عوامل حفاظت‌کننده فردی (IPFI)

Objectives: The purpose of this study was to check the psychometric properties of the Persian Individual Protective Factors Index (IPFI). Method: In the current survey, 481 high school students (243 girls) were recruited via multistage cluster sampling. Individual Protective Factors Index was prepared by translation and back translation, and then used for data gathering. Results: Factor analysis using principle component method revealed a 4-factor structure for the IPFI, namely Social Bonding, Personal Competence, Social Competence, and Social Coherence subscales. The correlation coefficient of the Social Bonding, Personal Competence, Social Competence, and Social Coherence with total score were 0.70, 0.78, 0.67 and 0.69, respectively (p≤0.01). The respective alpha coefficients for the above dimensions were 0.86 , 0.96, 0.82, and 0.82, respectively. The reliability was confirmed by the split-half method. Conclusion: The Persian IPFI is a valid and reliable research instrument.
