Introduction: Repetitive Negative Thinking (RNT) can be characterized as intrusive thoughts about worries (current, past, or future), negative experiences, and self-criticism, manifesting excessively and persistently. In a transdiagnostic process, it is identified that the RNT contributes to the onset and maintenance of multiple disorders. The present study aimed to adapt the Persistent and Intrusive Negative Thoughts Scale (PINTS) for the Brazilian context, investigating the psychometric qualities of the instrument. Method: Two studies were carried out with participants from different Brazilian states. In Study 1 (n = 258), the adaptation of PINTS and an exploratory factor analysis was performed. In Study 2 (n = 270), a confirmatory factor analysis was conducted, and evidence of convergent validity was gathered. Results: Firstly, in Study 1, a unifactorial structure of the measure was indicated. Through Study 2, the unifactorial structure was corroborated, demonstrating adequate internal consistency (precision), demonstrating that PINTS positively correlated with negative affectivity (stress, anxiety, and depression) and cognitive test anxiety. Conclusion: It is concluded that PINTS exhibited satisfactory metric qualities, being a brief and easy-to-administer measure, potentially serving as a useful tool for researchers investigating maladaptive repetitive negative thinking and its correlates.
