The aim of the present study was to examine the content validity and reliability of the newly developed Reaction Time and Defensive Slide Test (RTADST). Thirty-six female basketball players were recruited from three professional State Basketball league of Bosnia and Herzegovina clubs (age: 18.81 ± 2.58 years) who completed three separate trials of the RTADST with each trial consisting of fast shuffling movements left and right.  Each athlete performed the test 3 times in one day, and repeated testing was conducted the following day at evening basketball sessions. The RTADST relative reliability was evaluated by Cronbach’s alpha and ICC. Cronbach’s alpha coefficient was 0.81 which indicates good reliability. When recommendations from Bucheit et al. (2011) were taken into account, the value of ICC <0.69 indicated poor reliability. Absolute reliability of RTADST was assessed by CV, and its value was 5.3%, which is somewhat above the 5%, or the limit of acceptable reliability. Parameters of relative and absolute reliability after the exclusion of the first trial (familiarization with the test task), were more acceptable. Cronbach’s alpha coefficient was 0.90 and ICC = 0.82 compared to the one from all three trials. Considering absolute reliability, it could be concluded that the test is reliable since the CV value is below 5% (3.9%). Reliability between two days was assessed by ICC, and its value was 0.74, which confirms good reliability. Finally, the RTADST can be considered as a valid test that discriminates female basketball perimeter players and post players in reaction time and basketball defensive slide speed, while conditioning programs for the development of these abilities need to be carried out with a tool such is RTADST for the initial and final evaluation of these abilities.
