Evidence for an emotion-cognition interaction in the statistical prediction of suicide attempts

Suicidal behavior is a prevalent problem among adolescents and young adults. Although most theoretical models of suicide suggest that this behavior results from the interaction of different risk factors, most prior studies have tested only bivariate associations between individual risk factors and suicidal behaviors. The current study was designed to address this limitation by testing the effect of an emotion–cognition interaction on suicide attempts among youth. Specifically, we hypothesized that the interaction of emotion reactivity and problem-solving skills would statistically predict the probability of a recent suicide attempt among 87 adolescents and young adults. Results revealed a significant interaction, such that emotion reactivity was strongly associated with the probability of a suicide attempt among those with poor problem-solving skills, moderately associated among those with average problem-solving skills, and not significantly associated among those with good problem-solving skills. The next generation of studies on suicidal behavior should continue to examine how risk factors interact to predict this dangerous outcome.     

The interaction between the superhero ideal and maladaptive perfectionism as predictors of unhealthy eating attitudes and body esteem

Unhealthy eating attitudes and poor body esteem often lead to adverse outcomes (e.g., eating disorders). Prior research has identified two risk factors for these outcomes--endorsement of the superhero ideal and maladaptive perfectionism--and has suggested that these factors may interact to predict unhealthy eating attitudes and body esteem. The current study examined the interaction between the superhero ideal and maladaptive perfectionism as predictors of unhealthy eating attitudes and body esteem among 161 12- to 14-year-olds (74 males, 87 females). Maladaptive perfectionism moderated the relation between endorsement of the superhero ideal and unhealthy eating attitudes for girls only, such that endorsement of the superhero ideal was significantly associated with unhealthy eating attitudes only for adolescents with high levels of maladaptive perfectionism. The moderation model was not significant for body esteem. Prevention strategies should focus on reducing endorsement of the superhero ideal when there are high levels of maladaptive perfectionism.     

The Application of the Preschool Child Behavior Checklist and the Caregiver–Teacher Report Form to Mainland Chinese Children: Syndrome Structure,Gender Differences,Country Effects,and Inter-Informant Agreement

Preschool children have long been a neglected population in the study of psychopathology. The Achenbach System of Empirically Based Assessment (ASEBA), which includes the Child Behavior Checklist/1.5-5 (CBCL/1.5-5) and the Caregiver-Teacher Report Form (C-TRF), constitutes the few available measures to assess preschoolers with an empirically derived taxonomy of preschool psychopathology. However, the utility of the measures and their taxonomy of preschool psychopathology to the Chinese is largely unknown and has not been studied. The present study aimed at testing the cross-cultural factorial validity of the CBCL/1.5-5 and C-TRF, as well as the applicability of the taxonomy of preschool psychopathology they embody, to Mainland Chinese preschoolers. Country effects between our Chinese sample and the original U.S. sample, gender differences, and cross-informant agreement between teachers and parents were also to be examined. A Chinese version of the CBCL/1.5-5 and C-TRF was completed by parents and teachers respectively on 876 preschoolers in Mainland China. Confirmatory factor analysis (CFA) confirmed the original, U.S.-derived second order, multi-factor model best fit the Chinese preschool data of the CBCL/1.5-5 and C-TRF. Rates of total behavior problems in Chinese preschoolers were largely similar to those in American preschoolers. Specifically, Chinese preschoolers scored higher on internalizing problems while American preschoolers scored higher on externalizing problems. Chinese preschool boys had significantly higher rates of externalizing problems than Chinese preschool girls. Cross-informant agreement between Chinese teachers and parents was relatively low compared to agreement in the original U.S. sample. Results support the generalizability of the taxonomic structure of preschool psychopathology derived in the U.S. to the Chinese, as well as the applicability of the Chinese version of the CBCL/1.5-5 and C-TRF.     

The ontogenetic ritualization of bonobo gestures

Great apes communicate with gestures in flexible ways. Based on several lines of evidence, Tomasello and colleagues have posited that many of these gestures are learned via ontogenetic ritualization—a process of mutual anticipation in which particular social behaviors come to function as intentional communicative signals. Recently, Byrne and colleagues have argued that all great ape gestures are basically innate. In the current study, for the first time, we attempted to observe the process of ontogenetic ritualization as it unfolds over time. We focused on one communicative function between bonobo mothers and infants: initiation of “carries” for joint travel. We observed 1,173 carries in ten mother–infant dyads. These were initiated by nine different gesture types, with mothers and infants using many different gestures in ways that reflected their different roles in the carry interaction. There was also a fair amount of variability among the different dyads, including one idiosyncratic gesture used by one infant. This gestural variation could not be attributed to sampling effects alone. These findings suggest that ontogenetic ritualization plays an important role in the origin of at least some great ape gestures.
