The PSAS-BR-RSF-C total score showed moderate-to-strong and significant correlations with measures of anxiety (GAD-7;\n                      <jats:italic>r<\/jats:italic>\n                      = .52), depression (EPDS;\n                      <jats:italic>r<\/jats:italic>\n                      = .61), and self-criticism (SCS;\n                      <jats:italic>r<\/jats:italic>\n                      = .52), demonstrating good convergent validity.
