The　increasing　prevalence　of　sleep　disorders　among　university　students　should　be　taken　seriously.　Group　counseling　involving　a　mindfulness-based　strategy　may　help　prevent　students　from　developing　insomnia　and　subsequent　mental　health　disorders.　This　study　aimed　to　evaluate　the　ameliorating　effects　of　a　mindfulness-based　group　intervention　on　sleep　problems　and　emotional　symptoms　in　university　students　in　China.　Twenty-one　university　students　(16　females,　22.71　+/-　4.28　years)　who　were　not　on　medication　were　recruited　and　assigned　to　the　intervention　group　based　on　the　criterion　of　high　levels　of　sleep　problems.　Additionally,　twenty-four　university　students　(19　females,　24.50　+/-　0.93　years)　were　included　as　a　nonrandomized　control　group.　Individuals　in　the　intervention　group　participated　in　a　two-hour　group　intervention　once　a　week　for　eight　sessions.　All　participants　completed　self-reported　questionnaire　baseline　tests,　postintervention　tests,　and　one-month　follow-ups　on　mindfulness,　sleep　quality,　anxiety　and　depressive　symptoms.　Repeated-measures　ANOVA　was　performed.　The　results　revealed　significant　intervention　effects,　with　significant　differences　observed　between　the　two　groups　in　mindfulness　and　sleep　quality.　However,　there　was　no　significant　effect　of　the　intervention　on　anxiety　and　depressive　symptoms.　This　study　contributes　to　a　better　understanding　of　the　effectiveness　of　mindfulness-based　intervention　in　addressing　sleep　problems　in　university　students.
