bjective: The aim of this study is to translate the parental monitoring instrument (PMI) into Turkish and examine the psychometric properties of the Turkish version of PMI. Methods: A study was conducted with 532 adolescents aged 11-14 in grades 6-8 attending three schools in Izmir. Research materials included a Demographic Data Collection Form and the Parental Monitoring Instrument (PMI). In order to evaluate the validity of the instrument, content validity and confirmative factor test was performed for the structure validity. The knowledge regarding the reliability of the instrument was evaluated with the Cronbachs alpha internal consistency coefficient, test-retest technique and item-test correlation. Results: The average age of the participant students was found to be 12.20.9. Fifty-one percent of the students were female, 49% were male. The total variance explained in the Turkish form of the instrument was found to be 56.9% and the factor analysis supported the original construct. The Cronbachs alpha was evaluated as fairly reliable in seven factors. Item-to-total score correlations were determined in statistically significant levels and sufficient. The difference between the two measurements in all factors in the test-retest analysis was found to be statistically insignificant. Discussion: Based on these results the Turkish version of the PMI can be used as a valid and reliable instrument. PMI can be used in measuring the parental monitoring perceived by adolescents, in determining the relation between the risky behaviors and the parental monitoring and it can be guiding in planning the interventions directed to parents.
