AIM To validate a questionnaire for the diagnosis of orhorexia oervosa, an eating disorder defined as "maniacal obsession for healthy food". MATERIALS AND METHODS 525 subjects were enrolled. Then they were randomized into two samples (sample of 404 subjects for the construction of the test for the diagnosis of orthorexia ORTO-15; sample of 121 subjects for the validation of the test). The ORT...

In this paper chain cacti are considered. First, for two specific classes of chain cacti (orto-chains and meta-chains of cycles with h vertices) the recurrence relation for independence polynomial is derived. That recurrence relation is then used in deriving explicit expressions for independence number and number of maximum independent sets for such chains. Also, the recurrence relation for tot...

AIM The aim of the study was the validation and adaptation of the ORTO-15 Questionnaire in the group of the Polish schoolgirls and schoolboys. METHODS The study included 399 participants (15-21 years old), all of them high school students in the city of Sosnowiec. The ORTO-15 is a tool created in Italy by L.M. Donini, comprising of 15 items describing intensification of orthorexia risk (popul...

The five-coordinate Sn atom in the title mixed organyl stannate compound, (C(12)H(24)N)[Sn(C(5)H(9))(C(6)H(5))(2)(C(2)ClF(2)O(2))], is in a trans-C(3)SnO(2) trigonal-bipyramidal coordination environment. The NH(2) groups of the cations act as hydrogen-bond donors to two symmetry-related anions, resulting in the formation of linear chains. One of the phenyl rings is disordered over two sites wit...

BACKGROUND For a better differential diagnosis of eating disorders, it is necessary to investigate their subtypes and develop specific assessment tools to measure their specific symptoms. Orthorexia nervosa is an alleged eating disorder in which the person is excessively preoccupied with healthy food. The ORTO-15, designed by Donini and colleagues, is the first and only at least partially valid...

BACKGROUND Orthorexia nervosa (ON) is defined as pathological healthful eating. The aim of this study was to investigate whether there is any difference in orthorexic behaviours between clinical and non-clinical groups, and in different cultural contexts. . METHODS Recruitment involved both female patients with anorexia nervosa (AN) and healthy controls (HC) from Italy and Poland (N = 23 and ...

In the title mixed-organyl stannate, (C(12)H(24)N)[Sn(C(6)H(5))(2)(C(6)H(11))(CClF(2)O(2))(2)], there are two cations and two anions in the asymmetric unit. Each five-coordinate Sn atom shows trans-C(3)SnO(2) trigonal bipyramidal coordination. The four Sn-O distances are approximately equal in the two independent anions. Each ammonium cation serves as a hydrogen-bond donor to two stannates, the...

The aim of this study was the validation and analysis of the psychometric properties of a Spanish translation of the ORTO-15 questionnaire; an instrument designed to assess orthorexia nervosa behavior. Four hundred and fifty-four Spanish university students (65% women) aged between 18 and 51 years (M = 21.48 ± 0.31) completed the Spanish version of ORTO-15 and the Eating Disorders Inventory-2 (...
