To assess the presence of journal policies discouraging inappropriate author's self-citation (A-SC) in "Respiratory System" journals, we evaluated submission guidelines of "Respiratory System" journals included in Journal-Citation Reports 2020 (Clarivate Analytics®) for the presence of policies on A-SC and its impact on journals' self-citation (J-SC) rate and impact factor (IF). We found that 14.3% of journals (n=8/56) reported policies on inappropriate A-SC. The median IF was not different in "Respiratory System" journals with (3.6; IQR:2.3) vs without A-SC policies (3.1; IQR:3.0; p=0.41). The J-SC rate was not influenced by the presence of A-SC policies (p=0.83). Fully open-access (n=14) and traditional (n=42) journals had no differences in IF (3.3; IQR:1.5 vs 3.1; IQR:3.4, respectively; p=0.77) and J-SC rate (4.5%; IQR:5.6 vs 6.2%; IQR:8.4, respectively; p=0.38). The majority of "Respiratory System" journals do not have policies discouraging A-SC. The presence of such policies is not associated with changes in IF or J-SC rates.
