Background/purpose: The purpose of this study is to determine the degree of Machiavellian personality and how it relates to family communication patterns among Ajloun University College students in Jordan. The study seeks to determine whether there are statistically significant differences with regard to this issue based on academic year, gender, and academic specialization. Materials/methods: A descriptive methodological as well as correlational approach is employed to accomplish the study's goals, where a suitable sampling procedure is utilized to pick 570 students from Ajloun University College to administer the Machiavellian Personality Scale and the Family Communication Patterns Scale. Results: The findings indicated a modest degree of Machiavellian personality, where the most common family communication pattern was the balanced one, with the blaming pattern coming in last. Additionally, the results show a statistically significant difference in family communication patterns and Machiavellian personality depending on academic specialties, favoring the humanities, and a gender variable, favoring men. Based on the academic year variable, no statistically significant difference was discovered. Conclusion: In addition, the results show a statistically significant negative correlation between Machiavellian personality and the balanced pattern and a statistically significant positive correlation between Machiavellian personality and the distracting, blaming, placating, and super-reasonable family communication patterns.
