Latent class analysis of eating and impulsive behavioral symptoms in Taiwanese women with bulimia nervosa

Alternative methods of classifying eating disorders: Models incorporating comorbid psychopathology and associated features

“…Notably, 84% ( n = 51) of the women assigned empirically to the multi-impulsive class reported three or more non-eating related impulsive behaviors, consistent with clinical descriptions of multi-impulsive BN (n.b., the remaining 10 participants in the multi-impulsive class reported two non-eating-related impulsive behaviors). Tseng and Hu (2012) reported similar findings in a study of 180 women with BN in which LCA was used to classify participants on the basis of lifetime ED symptoms, number of purging methods (i.e., self-induced vomiting, laxative misuse, diuretic/diet pill misuse), and lifetime impulsive behaviors (viz., alcohol abuse, drug abuse, suicide attempts, self-harm, stealing, sexual promiscuity, and excessive buying). Three ED classes were identified: “impulsive multi-purgers,” ( n = 32), “non-impulsive multi-purgers” ( n = 75), and “non-purgers/uni-purgers” ( n = 75; p. 67).…”

“…Although much of this work has been conducted in individuals with bulimic syndromes (see, e.g., Corstorphine et al, 2007; Matsunaga et al, 2000; Myers et al, 2006; Wiederman & Pryor, 1996), there is evidence that multi-impulsivity occurs in individuals with AN, including those with the restricting subtype (Favaro et al, 2005; Nagata et al, 2000). Multi-impulsive EDs also are present in non-Western cultures (Matsunaga et al, 2000; Nagata et al, 2000; Tseng & Hu, 2012). …”

“…Finally, two studies have identified multi-impulsive ED subtypes using empirical methodology (Myers et al, 2006; Tseng & Hu, 2012). Myers et al employed latent class analysis (LCA) to characterize subtypes in 125 women with BN based on a lifetime history of impulsive behaviors (i.e., severe alcohol abuse or dependence, other drug abuse, sexual promiscuity, stealing, self-mutilation, and suicide gestures).…”

Latent class analysis for measuring Turkish People's future expectations for Turkey

“…Also, 21.4% are aged (18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29), 34.4% are (30-44), 32.4% are (45-64), and 11.8% are (65 +). In total, 5.2% do not know how to read or write, 48.3% are primary school graduates, 13.6% secondary school graduates, 19.8% are high school graduates and 13.1% are at least university graduates.…”

“…These studies are mainly in the fields of Social Sciences, Education and Psychology. See among others [3,11,21,25].…”
