This study examined associations between children's language ability and maternal cognitions about the intentionality and aversiveness of child behaviour, and mothers' reported harsh discipline responses to child misbehaviour. We tested associations with each type of cognition separately as well as in a single model to explore their unique associations. Participants included 69 mothers and their 18- to 37-month-old children. Mothers completed the Parenting Scale and were asked to rate the aversiveness and intentionality cognitions in response to eight common toddler problem behaviours. The Preschool Language Scale was administered to the children by an objective evaluator. A path analysis demonstrated that children's language ability was associated with maternal intentionality cognitions about their children's behaviour, which, in turn, was associated with mothers' harsh discipline. These findings highlight the importance of examining developmental markers of harsh parenting

This paper describes a feasibility study of a peer-delivered prevention intervention to identify mothers at high risk for depression and facilitate engagement in mental health services for their emotional health. Sixteen family peer advocates and their supervisors partnered with academic researchers over a period of six months to develop a four-session intervention that focused on identifying symptoms of depression, providing education about depression and treatment, actively linking caregivers to treatment for their own emotional health, and assisting caregivers in becoming active participants in their mental health care. Collaborating with peers to develop the model enhanced its perceived relevance and utility, and resulted in an intervention that was complimentary to their roles and the mission of peer-delivered support services. Peer/professional partnerships may be beneficial for enhancing the feasibility and acceptability of research efforts; the impact of peers' participation in the current project and the need for future research to develop and study peer-delivered models is discussed.

The current study examined the relationship between ethnicity and the age at which parents first become concerned about their children's development in 1478 toddlers with autism spectrum disorder (ASD) and atypical development. Based on the current findings, there were no racial/ethnic differences in age of parent's first concerns. Caregivers of toddlers with ASD first developed concerns around the same time independent of which ethnic groups they belong to. In addition, the age of caregivers' first concerns was significantly younger for those with ASD compared to those who are atypically developing without an ASD diagnosis. Implications regarding these findings are discussed. (c) 2014 Elsevier Ltd. All rights reserved.

This study examined: (1) qualitative aspects of close working relationships between family support organizations and child mental health agencies, including effective and ineffective characteristics of the relationship and aspects that they would change, and (2) the impact of the working relationship upon the family support organization. Semi-structured interviews were conducted with 40 directors of family support organizations characterized as having a close working relationship with a child mental health agency. Three main themes emerged regarding the quality of the working relationship: (a) interactional factors, including shared trust, communication, collaboration and service coordination; (b) aspects of the inner context of the family support organization, mental health agency, or both, including alignment of goals and values and perceptions of mental health services; and (c) outer contextual factors external to the organizations, such as financial and county regulations. Responses to the perceived impact of the relationship was divided into two themes: positive impacts (e.g. gained respect, influence and visibility), and negative impacts (e.g. lack of trust). This study lays the foundation for future research to better understand the mechanisms underlying interorganizational relationships in communities among different types of providers to create a more seamless continuum of services for families of children with mental health conditions.

OBJECTIVE:To explore the utility of clinician screening for anxiety in pediatric food-allergic patients. STUDY DESIGN/METHODS:In Phase I, 39 patients completed an anxiety questionnaire while their allergists completed a companion questionnaire estimating their patient's responses. Allergists then attended an educational workshop to improve their anxiety detection. In Phase II, following the workshop, questionnaires were completed by an additional 39 patients and their allergists. RESULTS:The percentage of clinician questionnaires with a "do not know" response decreased from 70% to 5% after the workshop. Correlation between allergists' and children's responses remained nonsignificant (r = .314, P = .321) before the workshop and after (r = .303, P = .068) and only 25% of patients who reported elevated anxiety were identified. Additionally, clinicians expressed poor acceptability of the screening. CONCLUSIONS:After the workshop, clinicians did not more accurately detect anxiety and found the process intrusive. Alternative methods for uncovering anxiety among high-risk patients are needed.

Memory flexibility is a hallmark of the human memory system. As indexed by generalization between perceptually dissimilar objects, memory flexibility develops gradually during infancy. A recent study has found a bilingual advantage in memory generalization at 18 months of age [Brito and Barr [2012] Developmental Science, 15, 812-816], and the present study examines when this advantage may first emerge. In the current study, bilingual 6-month-olds were more likely than monolinguals to generalize to a puppet that differed in two features (shape and color) than monolingual 6-month-olds. When challenged with a less complex change, two puppets that differed only in one feature--color, monolingual 6-month-olds were also able to generalize. These findings demonstrate early emerging differences in memory generalization in bilingual infants, and have important implications for our understanding of how early environmental variations shape the trajectory of memory development.

Human visuospatial functions are commonly divided into those dependent on the ventral visual stream (ventral occipitotemporal regions), which allows for processing the 'what' of an object, and the dorsal visual stream (dorsal occipitoparietal regions), which allows for processing 'where' an object is in space. Information about the development of each of the two streams has been accumulating, but very little is known about the effects of injury, particularly very early injury, on this developmental process. Using a set of computerized dorsal and ventral stream tasks matched for stimuli, required response, and difficulty (for typically-developing individuals), we sought to compare the differential effects of injury to the two systems by examining performance in individuals with perinatal brain injury (PBI), who present with selective deficits in visuospatial processing from a young age. Thirty participants (mean=15.1years) with early unilateral brain injury (15 right hemisphere PBI, 15 left hemisphere PBI) and 16 matched controls participated. On our tasks children with PBI performed more poorly than controls (lower accuracy and longer response times), and this was particularly prominent for the ventral stream task. Lateralization of PBI was also a factor, as the dorsal stream task did not seem to be associated with lateralized deficits, with both PBI groups showing only subtle decrements in performance, while the ventral stream task elicited deficits from RPBI children that do not appear to improve with age. Our findings suggest that early injury results in lesion-specific visuospatial deficits that persist into adolescence. Further, as the stimuli used in our ventral stream task were faces, our findings are consistent with what is known about the neural systems for face processing, namely, that they are established relatively early, follow a comparatively rapid developmental trajectory (conferring a vulnerability to early insult), and are biased toward the right hemisphere.

BACKGROUND:Sensory intolerance refers to high levels of distress evoked by everyday sounds (e.g., sounds of people chewing) or commonplace tactile sensations (e.g., sticky or greasy substances). Sensory intolerance may be associated with obsessive-compulsive (OC) symptoms, OC-related phenomena, and other forms of psychopathology. Sensory intolerance is not included as a syndrome in current diagnostic systems, although preliminary research suggests that it might be a distinct syndrome. OBJECTIVES/OBJECTIVE:First, to investigate the latent structure of sensory intolerance in adults; that is, to investigate whether it is syndrome-like in nature, in which auditory and tactile sensory intolerance co-occur and are associated with impaired functioning. Second, to investigate the psychopathologic correlates of sensory intolerance. In particular, to investigate whether sensory intolerance is associated with OC-related phenomena, as suggested by previous research. METHOD/METHODS:A sample of 534 community-based participants were recruited via Amazon.com's Mechanical Turk program. Participants completed measures of sensory intolerance, OC-related phenomena, and general psychopathology. RESULTS:Latent class analysis revealed two classes of individuals: those who were intolerant of both auditory and tactile stimuli (n=150), and those who were relatively undisturbed by auditory or tactile stimuli (n=384). Sensory-intolerant individuals, compared to those who were comparatively sensory tolerant, had greater scores on indices of general psychopathology, more severe OC symptoms, a higher likelihood of meeting caseness criteria for OC disorder, elevated scores on measures of OC-related dysfunctional beliefs, a greater tendency to report OC-related phenomena (e.g., a greater frequency of tics), and more impairment on indices of social and occupational functioning. Sensory-intolerant individuals had significantly higher scores on OC symptoms even after controlling for general psychopathology. CONCLUSIONS:Consistent with recent research, these findings provide further evidence for a sensory intolerance syndrome. The findings provide a rationale for conducting future research for determining whether a sensory intolerance syndrome should be included in the diagnostic nomenclature.

Leukocyte telomere length (LTL) is longer in association with advanced paternal age, but this association has not been examined along with family history (FH) in schizophrenia. LTL was measured by PCR and compared across cases and controls as part of a study to examine the characteristics of paternal age related schizophrenia. The 53 schizophrenia cases had similar mean LTL as 20 controls, although cases were significantly older than controls and overwhelmingly smoked cigarettes. Multivariate analyses showed that a FH of schizophrenia was associated with longer LTL in both male and female cases. Later paternal age was also related to longer LTL in male cases, but with shorter LTL in female cases. Male cases with older fathers and a FH had the longest LTL. The genetic architecture associated with a familial risk for schizophrenia may include pathways that lengthen LTL. Paternal aging conferred an additional increase in LTL lengthening in male cases, but reduced LTL in female cases. The gender difference in LTL for paternal aging is consistent with the severe illness features reported for female cases with older fathers and could implicate epigenetic alterations in the paternal X chromosomal region with advanced paternal age in association with the risk for schizophrenia.
