In a recent meta-analysis, only 53% of disorganized infants were predicted by parental Unresolved states of mind on the Adult Attachment Interview (AAI). The goal of this study was to identify additional predictors of infant disorganization on the AAI by developing and validating an interview-wide coding system for Hostile/Helpless (H/H) parental states of mind with respect to attachment. Maternal AAls were collected from 45 low-income mothers with high rates of childhood trauma when their children were age 7; Strange Situation assessments had been collected at 18 months of age. AAIs were independently coded using both the Main and Goldwyn coding system and newly developed codes for H/H states of mind. Results indicated that the H/H coding system displayed discriminant validity in that it did not overlap substantially with the Unresolved, Cannot Classify, or Fearfully Preoccupied by Traumatic Events categories in the Main and Goldwyn coding system. Second, H/H states of mind accounted for variance in disorganized infant behavior not associated with the Unresolved classification. Third, H/H states of mind were significantly related to maternal disrupted affective communication as coded by the Atypical Maternal Behavior Instrument for Assessment and Classification coding system, and maternal disrupted communication mediated the relations between H/H states of mind and infant disorganization.

Peer relationship difficulties and peer rejection are common in youngsters with attention-deficit hyperactivity disorder (ADHD), mandating focus on assessment issues, underlying reasons for peer approval and disapproval, links with comorbid aggression, and the mediating role of sociocognitive mechanisms as well as emotion regulation strategies. With previously unfamiliar ADHD and comparison boys who attended naturalistic summer research programs, we found the following: (a) parent and teacher estimates (but not self-reports) showed moderate correspondence with peer-nominated social preference; (b) ADHD boys were more likely than their comparison peers to accept other ADHD agemates; (c) aggression and noncompliance Predominated as self-reported reasons for rejecting agemates in both ADHD and comparison groups, with Perceived similarity the chief mediator of peer acceptance; (d) the high-aggressive subgroup of ADHD boys showed markedly worse peer sociometric status than did ADHD boys without aggression, for whom social isolation was also a predictor of peer reputation; and (e) self-reported social goals of a sensation-seeking nature and observed emotional reactivity characterized high-aggressive boys with ADHD and predicted end-of-program peer disapproval. We discuss implications for normal developmental processes and for intervention efforts.

This study of 45 high-risk mothers and infants examined the current indirect effects model of intergenerational transmission of disorganised attachment, which posits that maternal childhood experiences of loss or trauma contribute to maternal states of mind on the AAI which in turn contribute to infant disorganization. The severity of experiences of both abuse and loss were examined in relation to both Unresolved states of mind and Hostile-Helpless states of mind on the AAI and to infant disorganization at both 12 and 18 months. Neither the experiences of parental death in childhood nor the severity of abuse in childhood was related to Unresolved states of mind on the AAI. Instead, an Unresolved state of mind and the experience of parental death contributed independently and additively to the prediction of infant disorganization at 12 months. At 18 months, an indirect effects model was supported in relation to Hostile-Helpless but not Unresolved states of mind, in that severity of trauma had no direct relation to infant disorganization but severity of trauma was related to HostileHelpless states of mind which in turn predicted infant disorganization. Unresolved states of mind and experiences of parental loss did not add to prediction of disorganization at 18 months. The findings suggest that the influence of maternal trauma on infant attachment may become more prominent at 18 months as the infant makes the transition to toddlerhood. The results also suggest that a more complex etiologic model may be needed of the aspects of early experience that contribute to adult Unresolved states of mind on the AAI.

Children's emotion regulation strategies and parenting responses in a family task that elicited frustration are investigated by comparing core attention-deficit/hyperactivity disorder (AD/HD) symptomatology, emotional reactivity, and emotional regulation in the prediction of social behaviors and peer social preference. Participants were boys, ages 6-12 years, either with AD/HD (n = 45) or without problem behaviors (comparison; n = 34). A high-aggressive subgroup of AD/HD boys showed a significantly less constructive pattern of emotional coping than did both a low-aggressive AD/HD subgroup of boys and nondiagnosed comparison boys, who did not differ. With statistical control of core AD/HD symptomatology, noncompliance in a naturalistic summer camp was predicted by boys' overall emotion regulation and three specific strategies (emotional accommodation, problem solving, negative responses) during the parent-child interaction. Emotional accommodation and negative responses to the frustration task also marginally predicted social preference at the camp. These emotion regulation variables outperformed emotional reactivity in predicting such outcomes. Some emotion-related parenting behaviors were associated with child coping in the task. We discuss the relationship of emotion regulation to core AD/HD symptomatology and emotional reactivity, and the role of parents' behaviors in influencing children's emotional responses.
