The aim of this paper is to generalize the results on expansive mappings of Ye\c silkaya and Aydin from Fixed Point Results of Expansive Mappings in Metric Spaces [see Yeşilkaya, S. S.; Aydin, C. Fixed Point Results of Expansive Mappings in Metric Spaces. Mathematics 8 (2020), 1800]. In the present paper we show that the conditions imposed on the function can be relaxed. Thus, we present more general fixed point results for q-expansive mappings in metric spaces and prove some fixed point theorems for this class of mappings, via a different approach. Finally, we present some examples to support the new result.
