Brytek-Matera, Anna | Staniszewska, Anna | Hallit, Souheil
Although the amount of research about orthorexia nervosa (ON) has grown in the last two decades, to date, research on ON remains inconsistent. More is known about some behavioral characteristics of ON and its prevalence but nothing is known about the profile analysis behind this pathological eating behavior maintenance. Therefore, the objective of the present study was to determine the profiles of the participants in terms of eating behaviors, eating disorder psychopathology, obsessive-compulsive disorder symptoms and physical activity as well as check their association with ON. The sample was composed of 229 Polish female and male adults. Our findings showed three clusters and four-related factors (obsessive-compulsive disorder features; inappropriate eating and body-related behaviors; psychological and affective traits of eating disorders; perfectionism and behaviors associated with weight maintenance or weight loss). In our sample, a higher percentage of adults belonging to cluster 1 had no ON, whereas a higher percentage of adults belonging to cluster 3 had ON. Our results emphasize the possibility to target pathological eating behaviors and obsessive-compulsive disorder (OCD) symptoms in ON in psychological intervention.
