Abstract

Gratitude can be understood as a guide for life and ability to perceive and appreciate the positive in the world. The present study aimed to map how many and which instruments are available to measure gratitude, the circumstances of the evaluation and the predominant population. This systematic review located papers in four databases, resulting in a total of 36 papers. Of these, 16 original scales were found, and the remainder indicated as adaptations and validations. The main results show the numerical disparity of the perception of gratitude between genders and in relation to the age group evaluated. GQ-6 and GRAT are the most frequently used scales, with a greater variety of contexts and application audiences. The measures used to assess consistency have demonstrated, in most studies, concise reliability. It concludes by bringing the need for greater access to validated gratitude measures, in addition to the progress in the discussion regarding mental health
