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.

    • "Dance, on the other hand, is the second most popular leisure time physical activity after walking in women across all ages (25 to 75 years plus)[14]. Convincing benefits of dancing activities on physiologic, endocrine, cognitive and psychological levels have previously been shown15161718192021. Several studies revealed improved fitness, weight loss, reductions in cholesterol levels or inflammatory markers in women at risk after various forms of aerobic dancing[18,222324252627, including " aerobics " , " step aerobics " and " cultural dances " .

    • "It can also reduce disabling conditions caused by stress. Duberg et al. (2013) tried to determine whether dance affects self-rated health (SRH) of female adolescents from 13 to 18 years of age, suffering from psychosomatic symptoms and stress related problems. 59 girls were randomized into an experimental group, while 53 were randomized into a control group.

    ABSTRACT: Dance/movement therapy can be an effective method in helping individuals who are healthy and those with emotional and behavioral problems and other mental health problems. It is used as a psychotherapeutic or a healing tool, focusing on understanding and expressing one’s emotions. In order to investigate the effects and outcomes of dance/movement therapy in children and adolescents we reviewed the literature on dance/movement therapy from the year 2000 until now.

    ABSTRACT: The increasing prevalence of psychological health problems among adolescent girls is alarming. Knowledge of beneficial effects of physical activity on psychological health is widespread. Dance is a popular form of exercise that could be a protective factor in preventing and treating symptoms of depression. The aim of this study was to assess the cost-effectiveness of a dance intervention in addition to usual school health services for adolescent girls with internalizing problems, compared with usual school health services alone. A cost-utility analysis from a societal perspective based on a randomized controlled intervention trial was performed. The setting was a city in central Sweden with a population of 130 000. A total of 112 adolescent girls, 13–18 years old, with internalizing problems participated in the study. They were randomly assigned to intervention (n = 59) or control (n = 53) group. The intervention comprised dance twice weekly during eight months in addition to usual school health services. Costs for the stakeholder of the intervention, treatment effect and healthcare costs were considered. Gained quality-adjusted life-years (QALYs) were used to measure the effects. Quality of life was measured with the Health Utility Index Mark 3. Cost-effectiveness ratios were based on the changes in QALYs and net costs for the intervention group compared with the control group. Likelihood of cost-effectiveness was calculated. At 20 months, quality of life had increased by 0.08 units more in the intervention group than in the control group (P = .04), translating to 0.10 gained QALYs. The incremental cost-effectiveness ratio was USD $3,830 per QALY and the likelihood of cost-effectiveness was 95%. Intervention with dance twice weekly in addition to usual school health services may be considered cost-effective compared with usual school health services alone, for adolescent girls with internalizing problems.
