Maternal postpartum depression poses significant risks for mother-child interaction and long-term infant outcomes. Human immunodeficiency virus (HIV) status has also been implicated in the development of postpartum depression, but the association between maternal depression and infant social behavior in the context of HIV infection has not been fully investigated. First, we examined the relationship between maternal postpartum depression and infant social withdrawal at 10-12 months of age in HIV-infected mothers and infants. Second, we ascertained whether infant social withdrawal could be significantly predicted by maternal postpartum depression. The sample consisted of 83 HIV-infected mother-infant dyads. Mothers were assessed for postpartum depression with the Edinburgh Postnatal Depression Scale (EPDS), and infant social withdrawal behavior was rated using the Modified Alarm Distress Baby Scale (m-ADBB). 42.2% of the mothers scored above the cut-off point for depression on the EPDS, and a third of infants (31%) were socially withdrawn. Notably, maternal depression did not predict infant social withdrawal as measured by the m-ADBB. Infant social withdrawal was also not significantly associated with failure to thrive or gender. These preliminary findings need further investigation with respect to the impact on long-term neurodevelopmental and behavioral outcomes.

Attachment and attachment-related psychopathology has increasingly gained focus since Bowlby introduced the concept into the clinical repertoire. However, little has been done to explore attachment, or attachment-based interventions, within the context of intellectual disability. Clinical experience, however, has demonstrated significant attachment-related problems in children with intellectual disability. This article explores one such case of a 13-year-old girl with moderate intellectual disability and severe and persistent externalizing behavioural difficulties - biting, in particular. Once the severity of the behaviour was formulated within the framework of attachment, a structured attachment-focused parent-child intervention was designed in order to repair the damaged attachment between mother and daughter as a way of addressing the problematic behaviour. Outcomes demonstrated a sustained - immediately, at 3- and 6-month follow-up - positive impact of the intervention not only on the presenting problem but also on the quality of the relationship between mother and daughter. Research and clinical implications are discussed.

The Attachment and Biobehavioral Catchup intervention potentially offsets psychosocial risks facing dyads in which children have intellectual disability or developmental delays. In this single-case multiple-baseline study the efficacy of this intervention was tested across three such South African families. Maternal sensitivity, attachment security, and child affect regulation were measured weekly during a baseline and intervention period, using the Ainsworth Maternal Sensitivity Scales, Attachment Q-sort and salivary cortisol, respectively. Furthermore, post-intervention interviews invited parents’ and intervenors’ evaluations of the intervention. Visual analysis broadly indicated improvement in maternal sensitivity and attachment security across subjects over time following the introduction of the intervention, although randomisation tests were not statistically significant. Effects on affect regulation were not clearly observed and may have been influenced by case-specific variables. Parent-participants and intervenors also identified particularly helpful contributions from the intervention. Findings underscore the importance of individual-level effects evaluation, especially when implementing interventions outside the original population.
