Attachment & Child Health (ATTACH) pilot trials: Effect of parental reflective function intervention for families affected by toxic stress

Toxic stressors (e.g., parental violence, depression, low income) place children at risk for insecure attachment. Parental reflective function—parents’ capacity to understand their own and their child's mental states and thus regulate their own feelings and behavior toward their child—may buffer the negative effects of toxic stress on attachment. Our objective was to test the effectiveness of the Attachment and Child Health (ATTACH) intervention, focusing on improving reflective function and children's attachment security, for at-risk mothers and children <36 months of age. Three pilot studies were conducted with women and children from an inner city agency serving vulnerable, low-income families and a family violence shelter. Randomized control trial (n = 20, n = 10 at enrollment) and quasi-experimental (n = 10 at enrollment) methods tested the effect of the ATTACH intervention on the primary outcome of reflective function scores, from transcribed Parent Development Interviews. Our secondary outcome was children's attachment patterns from Ainsworth's Strange Situation Procedure. Despite some attrition, mixed methods analysis of covariance and t tests revealed significant differences in maternal, child, and overall reflective function, with moderate effect sizes. While more children whose mothers received the ATTACH program were securely attached posttreatment, as compared with controls, significant differences were not observed, which may be due to missing observations (n = 5 cases). Understanding the effectiveness of programs like the ATTACH intervention contributes to improved programs and services to promote healthy development of children affected by toxic stress.     

Treating destructive behavior reinforced by increased caregiver compliance with the participant's mands

Functional analyses sometimes do not identify momentary fluctuations in the function of destructive behavior (Bowman, Fisher, Thompson, & Piazza, 1997). In such cases, individuals may mand for the reinforcer that is currently most preferred and display destructive behavior if that mand goes unreinforced. In this study, we conducted a mand analysis to test whether destructive behavior functioned as a precurrent response that increased reinforcement for the participant's mands. We then evaluated a treatment that matched this function of destructive behavior by providing differential or time-based reinforcement of participant mands in accordance with multiple or chained schedules with reinforcement-schedule thinning. Decreases in destructive behavior averaged 97.4% across cases. We discuss these results relative to the importance of matching treatments for destructive behavior to operant functions for both traditional and idiosyncratic functions of destructive behavior.     

Measurement of nontargeted problem behavior during investigations of resurgence

Resurgence occurs when a previously extinguished behavior reemerges once a more recently reinforced behavior is placed on extinction. Previous research has suggested that nontargeted responses within the same response class recur alongside target-response resurgence (e.g., da Silva, Maxwell, & Lattal, 2008; Lieving, Hagopian, Long, & O'Connor, 2004). The purpose of this two-experiment investigation was to examine target response resurgence while simultaneously measuring the occurrence of nontargeted responses. Three children diagnosed with autism spectrum disorder who displayed multiple topographies of problem behavior participated. In Experiment 1, a three-phase resurgence procedure was conducted and all three participants displayed target-response resurgence accompanied by the emergence of nontargeted forms of problem behavior. These findings were replicated in Experiment 2 using a 30-min assessment procedure. The implications of these findings as they pertain to the treatment of severe problem behavior and utility of a brief relapse assessment are discussed.     

Beyond ‘Liberals’ and ‘Conservatives’: Complexity in Ideology,Moral Intuitions,and Worldview Among Swedish Voters

This research investigated the congruence between the ideologies of political parties and the ideological preferences (N = 1515), moral intuitions (N = 1048), and political values and worldviews (N = 1345) of diverse samples of Swedish adults who voted or intended to vote for the parties. Logistic regression analyses yielded support for a series of hypotheses about variations in ideology beyond the left–right division. With respect to social ideology, resistance to change and binding moral intuitions predicted stronger preference for a social democratic (vs. progressive) party on the left and weaker preference for a social liberal (vs. social conservative or liberal-conservative) party on the right. With respect to political values and broader worldviews, normativism and low acceptance of immigrants predicted the strongest preference for a nationalist party, while environmentalism predicted the strongest preference for a green party. The effects were generally strong and robust when we controlled for left–right self-placements, economic ideology, and demographic characteristics. These results show that personality variation in the ideological domain is not reducible to the simplistic contrast between ‘liberals’ and ‘conservatives’, which ignores differences between progressive and non-progressive leftists, economic and green progressives, social liberal and conservative rightists, and nationalist and non-nationalist conservatives.     

The effect of neonatal temperament on caregiver behavior in the newborn nursery

The research was conducted to determine whether temperamental characteristics of neonates influence caregiver behavior as early as the second day of life. Visual attentiveness, activity, and irritability of 28 healthy newborns were rated during six 30-minute sessions. Derived scores represented the infant's behavior during the total observation time and during specified caretaking activities. Several categories of nurturant behaviors and types of comments directed toward each infant by nurse-caregivers were coded during independent sessions. Variations in caregiver behavior were shown by Pearson correlations to be related to independently assessed differences among neonates. Alert babies received the most nurturant and social contact; active infants received the least contact, but the most comments that reflected concern about their health; irritable infants were soothed most. The data clearly suggest that emerging infant temperament plays a role in shaping the caregiving environment by the second day of life.
