Preventing eating pathology among elite adolescent ballet dancers: a pilot trial of the Athlete Body Project.

Adolescent ballet dancers are commonly recognized as aesthetic athletes who are at higher risk for body dissatisfaction, disordered eating, and eating disorders. Although athletic participation can generally protect against negative mental and physical health outcomes, idealization of a body ideal specific to ballet can confer unique vulnerability for eating pathology. Despite this known vulnerability, rigorous efforts to prevent eating pathology among young dancers are lacking. Previously, we reported on a trial of the Female Athlete Body Project adapted for professional female ballet dancers. The current study tested a subsequent adaptation, the Athlete Body Project (ABP), tailored for younger dancers, including a version for boys. This non-randomized, uncontrolled pilot trial tested ABP among boys and girls in two elite ballet schools (N = 23), formatted in-person and via video-conferencing. Program delivery met benchmarks for feasibility and acceptability across gender and delivery formats, and dancers provided positive qualitative feedback. Overall results suggest the potential of ABP in intervening on pre-post eating pathology and body appreciation, and significantly decreasing drive for muscularity among young ballet dancers. Taken together, this pilot work addresses a gap in the field and advances the needed development of eating disorder prevention programming for young, high-risk aesthetic athletes.

Mismatch negativity: no difference between controls and abstinent alcoholics.

BACKGROUND: A number of studies have examined the amplitude of the mismatch negativity (MMN) evoked potential as a measure of a brain inhibitory deficit in alcoholics or those at risk for alcoholism. The current study examined MMN in alcoholics abstinent an average of 6.7 years (with a minimum of six months abstinence) compared to controls. This study examined the association of MMN with alcoholism family history density, with indices of the presence and severity of externalizing disorders (a risk-factor for alcoholism), and with alcohol use variables. METHODS: Electroencephalograms were gathered on 76 subjects (38 controls, 38 abstinent alcoholics) during a nonattending mismatch negativity experiment. Measures of alcoholism family history density, disinhibited personality traits, and antisocial symptoms served as measures of risk-factors known to be associated with a genetic liability to alcoholism. Alcohol use variables were used as measures of alcoholism severity. RESULTS: There were no differences in MMN amplitude or latency between controls and abstinent alcoholics. There also were no significant associations between MMN measures and the measures of risk for alcoholism or with the severity of alcohol use or duration of abstinence. CONCLUSIONS: The results suggest that MMN is neither affected in chronic alcoholics nor associated with alcoholism vulnerability, and thus does not reflect a trait marker of alcoholism or alcoholism risk. The current results do not address effects on MMN of acute alcohol ingestion or withdrawal from alcohol.
