How do you tell the find command to NOT read sub-directories ( or from trying to

) when searching for a file?
/tmp directory list:
-rw-rw-r-- 1 brown dev 0 Jan 31 08:46 bar_1.txt
drwx------ 2 root root 182 Feb 23 16:50 smc898
drwx------ 2 webadmin webadmin 422 Feb 23 16:51 https-fpdbtst1.fuelman.com-ab0d7966
drwxr----- 2 oracle dba 179 May 17 12:26 hsperfdata_oracle
It is correctly finding the file and the messages about trying to access the sub-directories are not a big deal because I've got them going to a log file but I know there has got to be a way to tell "find" not to process sub-directories.
These are the 3 different command formats I've tried:
/tmp/ > find /tmp -name "bar_*.txt" -type f -prune -mtime +1
find: cannot read dir /tmp/smc898: Permission denied
find: cannot read dir /tmp/https-fpdbtst1.fuelman.com-ab0d7966: Permission denied
find: cannot read dir /tmp/hsperfdata_oracle: Permission denied
/tmp/bar_1.txt
/tmp/ > find /tmp -name "bar_*.txt" -mtime +1 -type f -prune
find: cannot read dir /tmp/smc898: Permission denied
find: cannot read dir /tmp/https-fpdbtst1.fuelman.com-ab0d7966: Permission denied
find: cannot read dir /tmp/hsperfdata_oracle: Permission denied
/tmp/bar_1.txt
/tmp/ > find /tmp -name bar_*.txt -mtime +1 -type f -prune
find: cannot read dir /tmp/smc898: Permission denied
find: cannot read dir /tmp/https-fpdbtst1.fuelman.com-ab0d7966: Permission denied
find: cannot read dir /tmp/hsperfdata_oracle: Permission denied
/tmp/bar_1.txt
