Sudden gains as a long-term predictor of treatment improvement among children in community mental health organizations

ObjectiveSudden gains have been described as rapid, sizeable changes observed between treatment sessions and have been associated with improved treatment outcome in adults. The current study examined weekly sudden gains among children seeking treatment in the community mental health setting.MethodParticipants were 161 children (age M = 10.58, SD = 1.73; 69.6% male; 47.8% Caucasian) and their parents who were randomized to one of three treatment modalities and were administered weekly and quarterly assessments throughout treatment.ResultsWhen idiographic (youth- and parent-identified “top problems”) and nomothetic measures (standardized checklists) were used to calculate sudden gains (i.e., gain must be large: in absolute terms, relative to prior session, and relative to changes in prior and subsequent sessions), 20–42% of participants experienced at least one sudden gain during treatment. Most sudden gains occurred early in treatment, and session content of relaxation was associated with sudden gain presence. Using a modified Bonferonni correction, sudden gains predicted overall symptom levels at final assessment (i.e., last assessment obtained following post-treatment) even after controlling for pre-treatment symptom levels and magnitude of the overall gain from pre- to post-treatment.ConclusionsSuddenness of gains may have a direct effect on long-term treatment outcome among children in the community.     

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.
