Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Following our study objectives, there are 5 main study parameters/endpoints. The main study parameters of the current study are the differences in levels of body image disturbances in adolescent girls with and without anorexia nervosa, based on experimental tasks and self-report measures. These measures allow us to test whether adolescents with AN experience their body size more different than adolescents without AN. The measures will be described in more detail below. The main endpoint of the Visual Size Estimation; the percentage of misestimations where a higher percentage indicates a larger overestimation. We expect adolescents with anorexia nervosa to obtain a higher percentage than adolescents without anorexia nervosa. The main endpoint of the Tactile Estimation task; the percentage of misestimations where a higher percentage indicates larger overestimation. We expect adolescents with anorexia nervosa to obtain a higher percentage than adolescents without anorexia nervosa. The main endpoint of the Hoop Task; the percentage of misestimation of hoop size. We expect adolescents with anorexia nervosa to obtain a higher percentage than adolescents without anorexia nervosa. The main endpoint of the cognitive-affective component of body image disturbances: all scores of all 20 items of the LAV summed up. The main endpoint of the behavioral component of body image disturbances: scores on all 27 items of the BCAQ summed up. | — |
Secondary
| Measure | Time frame |
|---|---|
| Following the objectives of our study, there is one secondary study parameters. The second study parameters are the covarying effects of Social (Appearance) Anxiety, fear for negative (appearance) evaluation and Intolerance of Uncertainty on body image disturbances in adolescent girls with and without anorexia nervosa. Self-report measures will be used and will be described in more detail below. The main endpoint of social anxiety as potential underlying mechanism for body image disturbances; scores on all three items on the mini SPIN summed up. The main endpoint of social appearance anxiety as potential underlying mechanism for body image disturbances; scores on all 17 items on the SAAS summed up. The main endpoint of fear for negative appearance evaluation as potential underlying mechanism for body image disturbances; scores on all 8 items on the FNAES summed up. The main endpoint of intolerance of uncertainty as a potential underlying mechanism for body image disturbances; scores on all 12 items on the IUS-12 summed up. The additional sub scales regarding Bodily IU (BIU) also consists of 12 items and the scores will be summed up. | — |
