Language outcome in autism: randomized comparison of joint attention and play interventions

This study reports results of a randomized controlled trial aimed at joint attention (JA) and symbolic play (SP) in preschool children with autism, with prediction to language outcome 12 months later. Participants were 58 children (46 boys) with autism between 3 and 4 years of age. Children were randomized to a JA intervention, an SP intervention, or control group. Interventions were conducted 30 min daily for 5-6 weeks. Assessments of JA skills, SP skills, mother-child interactions, and language development were collected at 4 time points: pre- and postintervention and 6 and 12 months postintervention by independent testers. Results indicate that expressive language gains were greater for both treatment groups compared with the control group, and results could not be explained by differences in other interventions in which children participated. For children beginning treatment with the lowest language levels, the JA intervention improved language outcome significantly more than did the SP or control interventions. These findings suggest clinically significant benefits of actively treating JA and SP skills in young children with autism.

Emotion regulation in the context of frustration in children with high functioning autism and their typical peers

BACKGROUND It is well accepted that emotion regulation difficulties are a serious concern for children with ASD, yet empirical studies of this construct are limited for this population. The present study describes group differences between high functioning children with autism and their typical peers in frustration and discrete coping strategies for emotion regulation. We also use sequential analyses to test differences in the efficacy of individual coping strategies at regulating childrens frustration. METHODS Subjects were 20 children with autism (M = 59 months) and 20 developmentally matched typically developing children (M = 50 months). Measures of childrens frustration (negative facial expressions and behaviors, negative vocalizations, resignation) and emotion regulation coping strategies were observationally coded from structured video recordings. RESULTS Children with autism displayed a higher intensity and duration of resignation, and the group difference became most pronounced when children worked alone during the parent-absent segment of the locked box task. Children with autism used significantly more avoidance and venting strategies, and fewer constructive strategies than typical children. Sequential analyses revealed that social support strategies (orienting and verbalizing to the experimenter) were ineffective for children with autism, while these behaviors, vocal venting, and distraction strategies were all effective for typically developing children. CONCLUSIONS The results go beyond the recent literature by offering a rich description of childrens efforts to regulate their frustration when faced with challenge, and point to important contextual differences in the efficacy of childrens coping strategies.

The Co-Regulation of Emotions Between Mothers and their Children with Autism

Thirty-four toddlers with autism and their mothers participated in an early intervention targeting joint engagement. Across the 24 intervention sessions, any significant distress episode in the child was coded for emotion regulation outcomes including child negativity, child emotion self-regulation, and mother emotion co-regulation. Results revealed that emotion regulation strategies by both mother and child were employed during distress episodes. An effect of intervention was found such that children decreased their expression of negativity across the intervention and mothers increased their emotional and motivational scaffolding. The results of this study indicate a positive effect of an intervention targeting joint engagement on emotion co-regulation outcomes.

A review of gene-environment correlations and their implications for autism: a conceptual model.

A conceptual model is proposed that explains how gene-environment correlations and the multiplier effect function in the context of social development in individuals with autism. The review discusses the current state of autism genetic research, including its challenges, such as the genetic and phenotypic heterogeneity of the disorder, and its limitations, such as the lack of interdisciplinary work between geneticists and social scientists. We discuss literature on gene-environment correlations in the context of social development and draw implications for individuals with autism. The review expands upon genes, behaviors, types of environmental exposure, and exogenous variables relevant to social development in individuals on the autism spectrum, and explains these factors in the context of the conceptual model to provide a more in-depth understanding of how the effects of certain genetic variants can be multiplied by the environment to cause largely phenotypic individual differences. Using the knowledge gathered from gene-environment correlations and the multiplier effect, we outline novel intervention directions and implications.

Ethnic Identity Development and Ethnic Discrimination: Examining Longitudinal Associations with Adjustment for Mexican-Origin Adolescent Mothers

Few studies examine normative developmental processes among teenage mothers. Framed from a risk and resilience perspective, this prospective study examined the potential for ethnic identity status (e.g., diffuse, achieved), a normative developmental task during adolescence, to buffer the detrimental effects of discrimination on later adjustment and self-esteem in a sample of 204 Mexican-origin adolescent mothers. Ethnic discrimination was associated with increases in depressive symptoms and decreases in self-esteem over time, regardless of ethnic identity status. However, ethnic discrimination was only associated with increases in engagement in risky behavior among diffuse adolescents, suggesting that achieved or foreclosed identities buffered the risk of ethnic discrimination on later risky behavior. Findings suggest that ethnic identity resolution (i.e., the component shared by those in foreclosed and achieved statuses) may be a key cultural factor to include in prevention and intervention efforts aimed to reduce the negative effects of ethnic discrimination on later externalizing problems.

Trajectories of Ethnic–Racial Identity and Autonomy Among Mexican-Origin Adolescent Mothers in the United States

This study examined trajectories of ethnic-racial identity (ERI) and autonomy development among Mexican-origin adolescent females in the United States (N = 181; M(age) at Wave 1 = 16.80 years, SD = 1.00) as they transitioned through the first 5 years of parenthood. Trajectories of ERI and autonomy also were examined in relation to psychosocial functioning. Unconditional latent growth models indicated significant growth in autonomy, ERI resolution, and ERI affirmation from middle to late adolescence. Conditional latent growth models indicated that autonomy and ERI exploration growth trajectories were positively associated with psychosocial adjustment. Although adolescent mothers are experiencing transitions that are not normative during adolescence, they also engage in normative developmental processes, and their engagement in such processes is linked with better adjustment.

Brief Report: Compliance and Noncompliance to Parental Control Strategies in Children with High-Functioning Autism and Their Typical Peers

The present study examined children’s compliance and noncompliance behaviors in response to parental control strategies in 20 children with high-functioning autism (HFA) and 20 matched typically-developing children. Observational coding was used to measure child compliance (committed, situational), noncompliance (passive, defiance, self-assertion, negotiation) and parent control strategies (commands, reprimands, positive incentives, reasoning, bargaining) in a clean-up task. Sequential analyses were conducted to identify parent behaviors that temporally predicted child compliance or noncompliance. Children with HFA were significantly more noncompliant and less compliant immediately following parents’ indirect commands than typically-developing children, even after controlling for receptive language. These results add to the existing literature on the efficacy of control strategies for children with autism, and have important implications for caregiver interventions.

Birth Characteristics and Developmental Outcomes of Infants of Mexican-Origin Adolescent Mothers: Risk and Promotive Factors.

Infants of adolescent mothers are at increased risk for negative developmental outcomes. Given the high rate of pregnancy among Mexican-origin adolescent females in the US, the present study examined health characteristics at birth and developmental functioning at 10 months of age in a sample of 205 infants of Mexican-origin adolescent mothers. Infants were relatively healthy at birth and had near average developmental functioning at 10 months. The educational attainment of adolescents and their mothers, and infants’ temperamental regulation, promoted positive developmental functioning, while the combination of low adolescent parental self-efficacy and high infant temperamental negativity was associated with greater developmental delay. Findings are discussed with respect to implications for prevention with this at-risk population of mothers and infants.

Measuring Social Support From Mother Figures in the Transition From Pregnancy to Parenthood Among Mexican-Origin Adolescent Mothers:

Social support for adolescent mothers, particularly from mother figures, can buffer risks and promote well-being. To date, no longitudinal research has investigated how the dimensions of social support may change during the transition from pregnancy to parenthood for adolescent mothers. This study examined stability and change in dimensions of social support from the third trimester of pregnancy to 2 years postpartum among 191 dyads of Mexican-origin adolescent first-time mothers and their mother figures. Perceptions of social support received from a mother figure shifted from a single dimension (i.e., global support) to three distinct factors (instrumental, emotional, and companionship support) during this transition; however, social support provision as reported by mother figures remained stable. Measurement equivalence was established across interview language (English and Spanish) and across two time points postpartum. Bivariate correlations provided support for the convergent and divergent validity of these measures. Implications for future research and practice are discussed.

Longitudinal relations among Mexican-origin mothers' cultural characteristics, cultural socialization, and 5-year-old children's ethnic-racial identification

The current longitudinal study examined the intergenerational transmission of ethnic–racial identity/identification and cultural orientation among Mexican-origin adolescent young mothers and their children (N = 161 dyads). Findings indicated that mothers’ ethnic–racial identity and their cultural involvement were significantly associated with children’s ethnic–racial identification via mothers’ cultural socialization; however, associations varied significantly by children’s gender and skin tone. For example, mothers’ ethnic–racial centrality was positively associated with cultural socialization efforts among mothers with sons (regardless of skin tone); but with daughters, a positive association only emerged among those with lighter skin tones. Associations between cultural socialization and children’s ethnic–racial identification also varied by children’s gender and skin tone. For example, the relation between mothers’ cultural socialization and children’s self-labeling as Mexican was positive for girls regardless of skin tone, and for boys with lighter skin tones, but was not significant for boys with darker skin tones. Findings highlight the critical role of children’s own characteristics, mothers’ ethnic–racial identity and adaptive cultural characteristics, and mothers’ cultural socialization efforts in the formation of young Mexican-origin children’s ethnic–racial identification.
