To investigate whether dance intervention influenced self-rated health for adolescent girls with internalizing problems.
Randomized controlled intervention trial with follow-up measures at 8, 12, and 20 months after baseline.
A Swedish city with a population of 130 000.
Girls aged 13 to 18 years with internalizing problems, ie, stress and psychosomatic symptoms. A total of 59 girls were randomized to the intervention group and 53 were randomized to the control group.
The intervention comprised dance classes twice weekly during 8 months. Each dance class lasted 75 minutes and the focus was on the joy of movement, not on performance.
Self-rated health was the primary outcome; secondary outcomes were adherence to and experience of the intervention.
The dance intervention group improved their self-rated health more than the control group at all follow-ups. At baseline, the mean score on a 5-point scale was 3.32 for the dance intervention group and 3.75 for the control group. The difference in mean change was 0.30 (95% CI, -0.01 to 0.61) at 8 months, 0.62 (95% CI, 0.25 to 0.99) at 12 months, and 0.40 (95% CI, 0.04 to 0.77) at 20 months. Among the girls in the intervention group, 67% had an attendance rate of 50% to 100%. A total of 91% of the girls rated the dance intervention as a positive experience.
An 8-month dance intervention can improve self-rated health for adolescent girls with internalizing problems. The improvement remained a year after the intervention.
探究舞蹈干预是否会影响有内化问题的少女的自我健康评估。
基线后 8、12 和 20 个月进行随访的随机对照干预试验。
人口 13 万的瑞典城市。
年龄在 13 至 18 岁之间、有内化问题（即压力和身心症状）的女孩。共有 59 名女孩被随机分配到干预组，53 名被随机分配到对照组。
干预包括 8 个月内每周两次的舞蹈课。每次舞蹈课持续 75 分钟，重点是运动的乐趣，而不是表演。
自我健康评估是主要结果；次要结果是对干预的依从性和体验。
舞蹈干预组在所有随访中自我健康评估的改善均优于对照组。基线时，5 分制的平均得分为 3.32 分（舞蹈干预组）和 3.75 分（对照组）。平均变化差值为 0.30（95%置信区间，-0.01 至 0.61），8 个月时为 0.62（95%置信区间，0.25 至 0.99），12 个月时为 0.40（95%置信区间，0.04 至 0.77），20 个月时为 0.40（95%置信区间，0.04 至 0.77）。在干预组的女孩中，67%的人出勤率为 50%至 100%。共有 91%的女孩认为舞蹈干预是一种积极的体验。
8 个月的舞蹈干预可以改善有内化问题的少女的自我健康评估。干预一年后仍有改善。
