This randomized controlled trial examined (a) the efficacy of a brief intervention designed to increase the rate of secure infant attachment, (b) the differential susceptibility hypothesis, and (c) whether maternal attachment styles moderated the expected Treatment x Irritability interaction in predicting infant attachment outcomes. Although there was no main effect of treatment, a significant Treatment x Irritability interaction revealed intervention effects for the highly irritable infants only, thus supporting one of two predictions of the differential susceptibility hypothesis: highly irritable infants would have disproportionately better outcomes than moderately irritable infants in better conditions (i.e., with intervention). When separate analyses were conducted with maternal attachment styles, we found significant three-way interactions among treatment, irritability, and each of the examined maternal attachment style dimensions (i.e., secure-fearful and dismissing-preoccupied). Specifically, with more secure mothers, beneficial effects of intervention emerged for highly irritable infants. For more dismissing mothers, the results revealed support for both predictions of the differential susceptibility hypothesis: highly irritable infants, compared to moderately irritable infants, were both more likely to be secure with intervention and less likely to be secure when in the control group. It is interesting that, for more preoccupied mothers, a treatment effect emerged only for moderately irritable infants. We discuss the implications of these findings for the differential susceptibility hypothesis as well as for early intervention.

Pregnant female offenders face multiple adversities that make successful parenting difficult. As a result, their children are at risk of developing insecure attachment and attachment disorganization, both of which are associated with an increased likelihood of poor developmental outcomes. We evaluated the outcomes of participants in Tamar's Children, a 15-month jail-diversion intervention for pregnant, nonviolent offenders with a history of substance abuse. All women received extensive wrap-around social services as well as the Circle of Security Perinatal Protocol (Cooper, Hoffman, & Powell, 2003). We present data on 20 women and their infants who completed the full dosage of treatment (a residential-living phase from pregnancy until infant age six months and community-living phase until 12 months). Results indicated that (1) program infants had rates of attachment security and attachment disorganization comparable to rates typically found in low-risk samples (and more favorable than those typically found in high-risk samples); (2) program mothers had levels of maternal sensitivity comparable to mothers in an existing community comparison group; and (3) improvement over time emerged for maternal depressive symptomatology, but not other aspects of maternal functioning. Given the lack of a randomized control group, results are discussed in terms of the exploratory, program-development nature of the study.

A significant body of longitudinal research suggests increased rates of mood disorders as well as depressive symptoms in youth diagnosed with attentiondeficit/hyperactivity disorder (ADHD) in contrast to non-ADHD comparison youth.Furthermore, individuals with co-occurring ADHD and mood disorders experience more serious impairments and worse outcomes than those with either disorder alone. iii

Ninety 6- and 7-year-olds (49.3% White, mostly middle class) from greater Washington, DC were randomly assigned to a subliminal priming condition (secure, happy, or neutral) to determine if attachment security priming decreases physiological, expressive, and self-reported fear reactions to threatening stimuli. Dispositional attachment security was also assessed. Secure priming and attachment security each decreased electrodermal reactivity, increased vagal augmentation, and decreased fearful facial expressions compared to control conditions. Examination of a statistical interaction between security priming and child attachment indicated that, although secure children had increased vagal augmentation and fewer fearful expressions than insecure children, the effects of priming were constant across secure and insecure children. There were no priming or attachment effects associated with children's self-reported fear.

Parental availability and responsiveness were experimentally manipulated to determine the effects on children's athletic performance. Fifty children (3-12-year-olds) ran as fast as possible around a softball diamond twice: once while parents were available and responsive and once while parents were unavailable and unresponsive (engrossed in mobile phone; order randomized and counterbalanced). Children ran about three seconds faster and were 17% less likely to trip, fall, or false start in the parental available and responsive condition. In addition, during only the available and responsive condition in which parents were instructed to watch their child and respond as they normally would, children ran faster as their parents' sensitivity increased. Similarly, children ran faster as parents' harshness decreased.
