The goal of the present study was to evaluate the psychometric properties of the English and Spanish versions of the Parenting Stress Index-Short Form (PSI-SF) with mothers of 12- to 15-month-old infants with elevated levels of behavior problems and from predominately Hispanic, low-income backgrounds. Mothers of 58 infants were assessed as part of a larger study examining a brief home-based intervention for infants with elevated behavior problems. Internal consistency was good for all three subscales (i.e., Parental Distress, Parent-Child Dysfunctional Interaction, and Difficult Child) and the Total Stress scale. Convergent validity of subscales was supported by correlations with measures of theoretically related constructs, including maternal depressive symptoms, maternal parenting practices, and infant behavior. Furthermore, examination of the optimal clinical cutoff by examining sensitivity and specificity suggested that for this high-risk sample lower percentile scores (73rd – 77th), relative to the published 85th percentile cutoff, were sufficient for identifying mothers with clinically elevated depressive symptoms and infants with clinically elevated behavioral and emotional difficulties. The current results provide psychometric support for the PSI-SF as an effective and appropriate measure for use with high-risk families that have been underrepresented in previous research, including mothers of very young children with behavior problems, Hispanic and Spanish-speaking populations, and low-income families.

To meet the mental health needs of infants from high-risk families, we examined the effect of a brief home-based adaptation of Parent-Child Interaction Therapy (PCIT) on improvements in infant and parent behaviors and reductions in parenting stress. Participants included 60 infants (55% male; average age of 13.5 ± 1.31 months) who were recruited at a large urban primary care clinic and were included if their scores exceeded the 75th percentile on a brief screener of early behavior problems. Most infants were from an ethnic or racial minority background (98%) and lived below the poverty line (60%). Families were randomly assigned to receive the home-based parenting intervention or standard pediatric primary care. Observational and parent-report measures of infant and parenting behaviors were examined at pre- and post-intervention and at 3- and 6-month follow-ups. Infants receiving the intervention were more compliant with maternal commands at the 6-month follow-up and displayed lower levels of externalizing and internalizing behavior problems across post and follow-up assessments compared to infants in standard care. Mothers receiving the intervention displayed a significantly higher proportion of positive and lower proportion of negative behaviors with their infant during play compared to mothers in the standard care group. There were no significant group differences for parenting stress. Results provide initial evidence for the efficacy of this brief and home-based adaptation of PCIT for infants. These findings highlight the benefit of identification and intervention as early as possible to promote mental health for infants from high-risk families.

The empirical studies reviewed demonstrate the increased risk for negative behavioral and cognitive outcomes following early childhood TBI. Furthermore, the review highlights current strengths and limitations of TBI research with young children and the need for multidisciplinary work examining outcomes for this vulnerable pediatric population.

Objective The current study examined the effect of Parent-Child Interaction Therapy (PCIT), a parent-training intervention for child behavior problems, on child language production. Method Participants were 46 children (ages 20-70 months) with externalizing behavior problems and with or at risk for developmental delay. Parent-child dyads were randomly assigned to a waitlist control or immediate treatment group. Parenting skills learned during PCIT (i.e., “do skills”) and children's word tokens and word types were measured at baseline and 4 months later. Results Findings suggest an indirect effect of parent do skills on the relation between group and child word types, such that more parent do skills predicted more child word types for families receiving PCIT. Conclusions The present study found that mothers’ use of child-directed skills played an important role in the growth and improvement of child language. Results suggest parent-training interventions targeting child behavior problems may also foster child language production.
