International studies reveal high prevalence of eating disorders (ED) and mental health issues amongst professional dancers, and the Norwegian National Ballet's house previously (2005) reported a lifetime prevalence of ED by 50% amongst female ballet dancers. Mental health issues and ED have been acknowledged for several years in most sports; still the same do not apply to dance sports. The objective of this study is to improve the knowledge on prevalence of mental health issues in professional dancers and the corresponding awareness of such among dance teachers. Additional objectives are to evaluate the effect of an intervention aimed to improve knowledge on nutrition, recovery strategies and mental health literacy among professional dancers and their teachers.
It is well documented that professional dancing increases the risk for, or strongly associates to, mental health issues like eating disorders, anxiety, and compulsive-obsessive disorders. As much as the international sport society has acknowledged the challenges on ED in sport, the same do not apply to dance. The point prevalence of ED in the general european population is about 0.3-4.0%, with a corresponding prevalence amongst professional dancers of 12.0-26.5%. Furthermore, the highest risk for ED among dance discipline is found to be within ballet. There are no reports on prevalence in Norwegian dancers; however, the Norwegian National Ballet's house reports a lifetime prevalence of 50% amongst ballet dancers. Previous studies have identified low knowledge and practice on performance nutrition and weight regulation strategies among dancers and their teachers. Findings indicates high risk of low energy availability, implying a high risk for the many associated negative effects on physical and mental health and performance capacity. Additionally, studies finds high levels of body dissatisfaction, body weight concern, perfectionism and low self-esteem, and also high prevalence of anxiety and depression. Several intervention studies finds positive effect on body dissatisfaction, disordered eating behaviour, nutritional intake in sport athletes, and also in ballet dancers in the US and Canada. Nevertheless, so far there haven't been any intervention in Norwegian dancers. The objective with this study is to explore mental health in professional dancers and their knowledge on recovery strategies and nutritional needs, and to implement and evaluate the effect of an intervention designed to improve these aspects. A group of performance art students serves as control to the intervention effect. Additionally this study evaluates the knowledge of these issues amongst dancers and how to deal with such issues, in dance teachers, and aims to implement and evaluate the effect of an intervention designed to improve the knowledge on these aspects.

Change in symptoms of eating disorders
Eating disorder examination questionnaire (EDE-q) by Prof. Fairburn validly assesses the frequency and severity of ED features to produce ED diagnoses according to the DSM-5. It constitutes 22 items scored on a Likert scale from 0-6 and 6 items in which a number of frequency is given for a given eating behavior. The questionnaire is averaged with a global scale and 4 subscales, in which a higher value indicates higher clinical severity. The global score cut-off score indicating probability of an eating disorder in the Norwegian female population is 2.5.
Time frame: Pre-intervention, post-intervention (4-months), and follow up (6-months post-intervention)
Change in perfectionism
Children and adolescent perfectionism scale (CAPS) is a 22-item measure of perfectionism in children and adolescents, compromising two subscales; self-oriented perfectionism (12 items) and social-oriented perfectionism (10 items). Questions rates from 1 (false - not at all true) to 5 (very true for me); hence a higher value indicates higher level of perfectionism.
Time frame: Pre-intervention, post-intervention (4-months), and follow up (6-months post-intervention)
Change in resilience
Resilience scale for adults (RSA) can be used to assess the presence of protective factors important to regain and maintain mental health. It is a self-report instrument for evaluating six protective dimensions of resilience in adults: (1) Perception of the Self, (2) Planned Future, (3) Social Competence, (4) Family Cohesion, (5) Social Resources, (6) Structured Style. The RSA has 33 items; item-response ranges from one to seven; higher scores reflect higher levels of protective factors of resilience.
Time frame: Pre-intervention, post-intervention (4-months), and follow up (6-months post-intervention)
Change in self esteem
Rosenborg Self esteem inventory by Rosenberg, M. (1965). A 10-item scale that measures global self-worth by measuring both positive and negative feelings about the self. The scale is believed to be uni-dimensional. All items are answered using a 4-point Likert scale format ranging from strongly agree to strongly disagree.
Time frame: Pre-intervention, post-intervention (4-months), and follow up (6-months post-intervention)
Change in body appreciation
Body appreciation scale (BAS-2) by Avalos et al 2005. The 10-item Body Appreciation Scale ) assesses individuals' acceptance of, favorable opinions toward, and respect for their body. Each item is scored on a Likert scale from 1-5, and global score is the average score for items 1-10.
Time frame: Pre-intervention, post-intervention (4-months), and follow up (6-months post-intervention)
Change in energy availability
Low energy availability in females questionnaire (LEAF) and Low energy availability in males questionnaire (LEAM). The LEAF-Q was developed to screen for LEA in female athletes, and measures occurrence of injuries, gastrointestinal dysfunction (GD) and menstrual irregularities (MI) related to low energy availability. Suggested cut-off's's for GD, MI, and for the total LEAF-Q score are ≥2, ≥4, and ≥8, respectively, with higher scoring indicating more severe clinical condition. The LEAM-q is a male-adapted version of the questionnaire, which is currently under validation.
Time frame: Pre-intervention, post-intervention (4-months), and follow up (6-months post-intervention)
Change in depression and anxiety
Hopkins symptom check list (SCL-10) is used to measure psychological distress among adolescents and adults; designed to measure the symptoms of anxiety and depression. Four of the ten questions are about anxiety and six are about depression. All 10 questions have 4 response categories: 'Not at all', 'A little', 'Quite a bit' and 'Extremely'. The responses are summarized across all items and the mean score is used as a measure of psychological distress. An average score ≥1.85 is considered a valid cut-off value for prediction of mental distress.
Time frame: Pre-intervention, post-intervention (4-months), and follow up (6-months post-intervention)
