Narrative:
During our flight; we encountered some moderate chop during the climbout. I had the flight attendants (F/as) remain seated until we were above the cumulus clouds (approximately 16;000 ft). Once we were above the clouds; it was a smooth ride. During our climb to FL380; ATC stopped us at FL370. After sitting at FL370 for a while; ATC told us to turn right 10 degrees for a climb. During our climb at approximately FL378; we encountered a very abrupt roll to the left (approximately 15-20 degrees of roll). We assumed it was wake turbulence because of the nature of the roll; plus we noticed an aircraft at our 11 o'clock position and approximately five miles. I immediately turned on the seatbelt sign and called to check on the F/as and passengers. None of the passengers were hurt; however; [some of the] F/as said that their neck and shoulders were hurting. I asked if they were going to need emts to meet the aircraft and they declined. I also inquired if they were going to be able to man their positions and perform their duties. They said yes. I notified dispatch via ACARS and requested an inflight supervisor and csr meet the flight.
