AbstractThe co-occurrence of behaviors of attention-deficit/hyperactivity disorder (ADHD) with behaviors of anxiety or behaviors of depression is the norm, but little is known on how the co-occurrence accounted for youths’ peer relations. The authors report results on difficult peer relations in relation to behaviors of ADHD, co-occurring behaviors of depression, and behaviors of anxiety from three studies on 862 youths in China and in the United States. Study 1 included 313 ethnically and socioeconomically diverse American youths; Study 2 included 250 youths who were adopted out of Chinese orphanages by American parents; and Study 3 included 299 youths from Beijing, China. Data on difficult peer relations and behaviors of ADHD, depression, and anxiety were collected with the third edition of Behavior Assessment System for Children-Self Report of Personality. In all three studies, each type of problems alone significantly predicted difficult peer relations, but behaviors of ADHD were not significant when co-occurring behaviors of depression or co-occurring behaviors of anxiety were considered. Despite that the youths in our study had different cultural and personal backgrounds, there was no evidence that behaviors of ADHD were detrimental to youths’ peer relations when behaviors of depression or anxiety were considered. Implications for intervention were discussed. 相似文献

In Switzerland, the highest rates of suicide are observed in persons without religious affiliation and the lowest in Catholics, with Protestants in an intermediate position. We examined whether this association was modified by concomitant psychiatric diagnoses or malignancies, based on 6,909 suicides (ICD‐10 codes X60‐X84) recorded in 3.69 million adult residents 2001–2008. Suicides were related to mental illness or cancer if codes F or C, respectively, were mentioned on the death certificate. The protective effect of religion was substantially stronger if a diagnosis of cancer was mentioned on the death certificate and weaker if a mental illness was mentioned. 相似文献

Abstract For the last 40 years I am trying to make Magic. First as a dancer and choreographer, creating performances and dance pieces, then using the skills I acquired in the theater and applying them to sex-positive spaces. What I describe here is not an academic thesis or a philosophical text. All the knowledge about Making Magic that I propose is derived from practical experience. It is a method developed in 40+ years working with and observing the body, while choreographing dance, group processes, and social events. 相似文献
