Checklist for Single Subject Research Design
• Is there any similarity in the target behavior when two subjects were placed?
• Is the level of age almost same to each other when two subjects were placed?
• Is direct observation utilized to identify the target subject's character?
• Is test instrument used to identify the target subject's character?
• Is there any relationship between target behavior and the notice of subject's character?
• Is there any standard to recruit subject?
• Is there any logical basis to recruit the subject?
• Is a definition of target behavior set in detail and operative?
• If the target behavior is related to the behavior problem, is functional test ready before the baseline trial?
• Is the description provided about advantage as well as resource added to the behavior problem of the target subject with disability or typical clinical condition?
• Is the intervention selected through behavior problem understanding?
• Is there comment related to the report sheet?
• Is the right reaction and wrong reaction defined in detail?
• If there is the score to be earned, is the gap within scores appropriately distributed?
• Are the record method and procedure described properly?
• Has the reliability been secured between observers?
• Is there comment related to 2nd or 3rd observer?
• Is the observer trained?
• Is there a standard to end of observation?
• Is the in-service training provided for the observer?
• Is there any notice when the reliability was secured?
• Is there a formula for the reliability calculation?
• Is the intervention described in detail to repeat?
• Is there comments about intervenor?
• Is the experimental setting familiar to the researcher?
• Is the environment of experimental setting described in detail?
• Is the social circumstance of experimental setting described in detail?
• Is the reason to choose test instrument was described in detail?
• Is there the procedure to select test instrument prior to the experiment?
• Is the faithfulness considered?
• Is there a formula to calculate the faithfulness?
• Is there a training plan for the intervenor to increase the faithfulness?
• Is there any description related to the social validity of the faithfulness?
• Is the experiment design explained?
• Is there an agreement between noted experimental design and real design?
• Is the reason explained why the experiment design is selected?
• Is the total period of experiment noticed?
• Is the explanation related to the condition and difference of baseline and intervention?
• Is the time of switching intervention from the baseline appropriate?
• If the training period set separately, is the reason described?
• Is the reason to end of intervention described?
• In the case of multiple baseline design, is the standard of intervention to different situation or target behavior described in detail?
• Is the explanation related to the intervention and withdrawal described with its difference?
