Efficient Estimation of Children's Language Exposure in Two Bilingual Communities

Purpose The language that children hear early in life is associated with their speech-language outcomes. This line of research relies on naturalistic observations of children's language input, often captured with daylong audio recordings. However, the large quantity of data that daylong recordings generate requires novel analytical tools to feasibly parse thousands of hours of naturalistic speech. This study outlines a new approach to efficiently process and sample from daylong audio recordings made in two bilingual communities, Spanish–English in the United States and Quechua–Spanish in Bolivia, to derive estimates of children's language exposure. Method We employed a general sampling with replacement technique to efficiently estimate two key elements of children's early language environments: (a) proportion of child-directed speech (CDS) and (b) dual language exposure. Proportions estimated from random sampling of 30-s segments were compared to those from annotations over the entire daylong recording (every other segment), as well as parental report of dual language exposure. Results Results showed that approximately 49 min from each recording or just 7% of the overall recording was required to reach a stable proportion of CDS and bilingual exposure. In both speech communities, strong correlations were found between bilingual language estimates made using random sampling and all-day annotation techniques. A strong association was additionally found for CDS estimates in the United States, but this was weaker at the Bolivian site, where CDS was less frequent. Dual language estimates from the audio recordings did not correspond well to estimates derived from parental report collected months apart. Conclusions Daylong recordings offer tremendous insight into children's daily language experiences, but they will not become widely used in developmental research until data processing and annotation time substantially decrease. We show that annotation based on random sampling is a promising approach to efficiently estimate ambient characteristics from daylong recordings that cannot currently be estimated via automated methods.

Pathological demand avoidance in children and adolescents: A systematic review

Requests for pathological demand avoidance diagnoses have increased over recent years but pathological demand avoidance remains a controversial issue. We undertook a systematic review of peer-reviewed studies of pathological demand avoidance, using standardised appraisal and synthesis methods, to assess how pathological demand avoidance is identified and to explore the relationships between pathological demand avoidance, autism and other developmental/psychiatric disorders. A search of PsycINFO/PubMed/MEDLINE/Embase identified 13 studies meeting inclusion criteria. Narrative synthesis was chosen due to methodological heterogeneity of the identified studies. Autistic children/adolescents constituted the majority of participants in most studies. Most studies provided clearly defined inclusion criteria together with adequate descriptions of participants and study settings. Almost all studies relied on the parental report of pathological demand avoidance symptoms/diagnosis. Identification of pathological demand avoidance in all studies seemed to be, directly or indirectly, based on the criteria developed by Newson et al. While eight studies used objective criteria for the identification of pathological demand avoidance, the measures used have methodological limitations. Though associations with anxiety have been reported, few studies took account of possible relationships between pathological demand avoidance and other conditions, such as anxiety. Methodological limitations restrict current conclusions regarding the uniformity or stability of the constellation of behaviours associated with pathological demand avoidance or the characteristics of individuals displaying them. Clinical implications of current research are discussed. Lay Abstract Requests for diagnoses of pathological demand avoidance have increased over recent years, but pathological demand avoidance remains a controversial issue. The concept of pathological demand avoidance has been criticised for undermining the self-advocacy of autistic people and neglecting the potential role of anxiety as a possible underlying or contributing cause. The current study was undertaken to summarise and review the methodological quality and findings from current research into pathological demand avoidance in children and adolescents. Further aims were to describe how pathological demand avoidance has been identified and to explore the relationships with autism and other developmental and psychiatric disorders. After a comprehensive search, 13 relevant studies using a wide range of methods were identified and systematic quality assessments were undertaken. All the studies had based the identification of pathological demand avoidance, directly or indirectly, on descriptions from the original study by Newson and colleagues. However, the methods used to develop these criteria were not clearly described. Most studies relied exclusively on parental report for data, and there was a general failure to take account of alternative explanations for the behaviours under study. No studies explored the views of individuals with pathological demand avoidance themselves. Problems concerning definition and measurement in the reviewed studies currently limit any conclusions regarding the uniformity or stability of the behaviours described, or the characteristics of individuals displaying them. Relationships between pathological demand avoidance and other emotional and behavioural difficulties should be explored in future research, as should the perspectives of individuals with pathological demand avoidance themselves.

Estimated Prevalence of Unreported IGD Cases in Routine Outpatient Children and Adolescent Psychotherapy

Internet Gaming Disorder (IGD) has been included in the DSM-5 as a diagnosis for further study, and Gaming Disorder as a new diagnosis in the ICD-11. Nonetheless, little is known about the clinical prevalence of IGD in children and adolescents. Additionally, it is unclear if patients with IGD are already identified in routine psychotherapy, using the ICD-10 diagnosis F 63.8 (recommended classification of IGD in ICD-10). This study investigated N = 358 children and adolescents (self and parental rating) of an outpatient psychotherapy centre in Germany using the Video Game Dependency Scale. According to self-report 4.0% of the 11- to 17-year-old patients met criteria for a tentative IGD diagnosis and 14.0% according to the parental report. Of the 5- to 10-year-old patients, 4.1% were diagnosed with tentative IGD according to parental report. Patients meeting IGD criteria were most frequently diagnosed with hyperkinetic disorders, followed by anxiety disorders, F 63.8, conduct disorders, mood disorders and obsessive-compulsive disorders (descending order) as primary clinical diagnoses. Consequently, this study indicates that a significant amount of the clinical population presents IGD. Meaning, appropriate diagnostics should be included in routine psychological diagnostics in order to avoid “hidden” cases of IGD in the future.

Plant Experience Questionnaire (Rioux & Wertz 2021)

A growing body of research investigating plant-related cognition and behaviors demonstrates that plants have shaped human minds and societies and that pursuing empirical research in this area can yield new insights into many aspects of human cognition and development, including food learning, danger avoidance, and cultural transmission. This research would greatly benefit from a validated measure that assesses experience with plants early in life. Here we present the validation of a new measure to assess such experience: The Plant Experience Questionnaire (PEQ), filling a major gap in the literature on plant-related cognition in infancy and early childhood. The PEQ was tested on a sample of 576 caregivers who completed the questionnaire about their child (age = 5-81 months). Factorial analysis revealed a four-dimensional structure of the questionnaire: (1) experience with indoor plants, (2) experience with outdoor plants, (3) eating from plants, and (4) parental prohibition from touching plants. The PEQ displayed good psychometric properties as shown with satisfactory internal consistency and convergent and discriminant validity and is suitable for a broad age range from infancy to early childhood. Therefore, the PEQ is an efficient and valuable tool for assessing plant experience in early life via parental report.

Parental Feeding Concerns for Children With Autism Spectrum Disorder: A Family-Centered Analysis

This study identifies and describes feeding concerns of parents of children with autism spectrum disorder (ASD) and examines the extent to which parents relate those concerns as having been addressed by therapists. Survey data were collected from 113 parents of children with ASD. Of the parents surveyed, 68% described a past or present concern with feeding; 60% of those parents with concerns said a therapist had not addressed those concerns. Feeding concerns were more likely addressed when therapists shared parent’s concerns. Specific types of concerns, such as those around food selectivity and food refusal, were more likely addressed than difficulties around mealtime. A gap is identified between parental report of feeding difficulties and parental report of professional services addressing feeding needs. This analysis presents an opportunity for occupational therapists in the area of feeding, particularly around identifying and addressing parental concerns.
