Understanding and Improving the Validity of Self-Report of Parenting

Although researchers using parental self-report data have questioned its validity (Holden, 2001) and called for more work in this area (Krevans & Gibbs, 1996; Locke & Prinz, 2002), methodological concerns regarding self-report about parenting practices have not been addressed adequately. The susceptibility of parental report to systematic distortions suggests a need for research on ways to improve self-report. This paper attempts to synthesize research findings from other fields (e.g., survey methodology) about ways to improve the validity of self-report, and to discuss the implications for self-report of parenting behaviors. Methods for improving self-report are presented for each of the 5 major tasks in responding to a question: (1) understanding the question, (2) recalling relevant behavior, (3) inference and estimation, (4) mapping the answer onto the response format, and (5) “editing” the answer for reasons of social desirability. Self-administered interviewing, audio-computer-assisted interviewing, pretesting, conversational interviewing, and the decompositional item may be among the best candidates for use in parental self-report. Recommendations are offered with respect to strategies that might prove useful in improving parental assessment of parenting, and to research efforts to evaluate the utility and potential costs of these strategies.     

Louis Couturat,modern logic,and the international auxiliary language

ABSTRACT

To some extent, the early twentieth century revival of universal languages was the work of logicians and mathematicians. Pioneers of modern logic such as Frege, Russell and Peano wanted to overcome the diversity and deficiencies of natural languages. Through the rigour of formal logic, they aimed at providing scientific thinking with a reliable medium free from the ambiguity and inconsistencies of ordinary language. This article shows some interconnections between modern logic and the search for a common tongue that would unite scientists and people of all nations. The French mathematician and philosopher Louis Couturat is a key figure in understanding the interplay between these two movements. Through his work in composing the Ido language as an alternative to Esperanto, Couturat gave a new life to the Leibnizian idea of a universal characteristics. In addition, his multifaceted work provides a valuable insight into some political implications of early analytic philosophy.

Comparing the Patrologia Latina and the CETEDOC Library of Christian Latin Texts Databases from a User's Perspective

ABSTRACT

This review article provides a detailed comparison of two major patristic databases, the Patrologia Latina and the CETEDOC Library of Christian Latin Texts from a user's perspective.     

Developmental Delays at Arrival,Early Intervention Enrollment,and Adopted Chinese Girls’ Academic Performance and Internalizing Problems in Adolescence

The author investigated the extent of developmental delays in girls adopted from China, their subsequent early intervention (EI) enrollment, and how the delays and EI were related to their academic performance and internalizing problems in adolescence. The sample included 180 adolescent girls (M = 13.4 years, SD = 2.0 years) who were adopted at 3–23.5 months (M = 11.5 months, SD = 3.7 months). Data on the adopted Chinese girls’ delays at arrival and EI enrollment in physical therapy (PT) and speech–language therapy (SLT) were collected from the adoptive mothers at the Baseline; data on the adopted Chinese girls’ present academic performance and internalizing problems were collected from the adoptive mothers and adopted girls at Wave 4 six years later. Data analyses revealed that 55% of the adoptees had moderate-to-severe delays when first arrived at the adoptive homes. Motor delays significantly increased the odds for PT (odds ratio [OR] = 3.98, 95% CI [2.18, 7.82], p <.001) and SLT (OR = 2.36, 95% CI [1.50–3.72, p <.001). Social-cognitive delays also significantly increased the odds for PT (OR = 1.90, 95% CI [1.36, 2.63], p <.001) and SLT (OR = 1.63, 95% CI [1.22, 2.17], p <.001). Motor delays were negatively associated with academic performance but positively associated with internalizing problems. General linear modeling showed that the adoptees who had developmental delays at arrival and subsequently enrolled in EI scored significantly lower on academic performance than their peers who had delays but did not enroll in EI, as well their peers who had no delays and did not enroll in EI. Implications of these findings are discussed.     

Self-Perceived Peer Acceptance in Preschoolers of Differing Economic and Cultural Backgrounds

Self-evaluation begins in early childhood and becomes more nuanced as children get older. However, little is known about the specific factors that predict self-perception and in particular peer acceptance, early in life. This is especially true for low-income children and children of different ethnicities. This study examined 4-year-old children's feelings of social acceptance relative to teachers' perceptions. It also explored whether temperament, language skills, traditional parenting, and teachers' perceptions of peer acceptance were related to children's self-perceptions. Using 94 preschoolers from different cultural and economic backgrounds as participants, results of a mixed model analysis of variance indicated that the relation between children's self-perceptions and teachers' ratings were not uniform across economic and cultural groups. In addition, results of hierarchical multiple regression analyses demonstrated that traditional parenting was one of the strongest predictors of children's social self-perceptions. Beyond parenting, children with relatively good verbal skills, who were not temperamentally shy, tended to perceive themselves as socially competent.     

The Semantics of Secrecy: Young Children's Classification of Secret Content

The authors explored whether young children can distinguish potential secrets from nonsecrets by their content, as can older children, adolescents, and adults. Ninety children, 4, 5, and 6 years old, rated the secrecy of items from an adult-validated list of personal information about an age- and gender-appropriate puppet. Two factors of the children's data corresponded to the adult categories of nonsecrets and secrets, and a third factor corresponded to surprises. All ages rated surprises as significantly more secret than nonsecret items; however, the surprise items contained linguistic cues to secrecy. A tendency to rate nonsecrets as secret decreased with age, but only the 6-year-olds rated secrets other than surprises as significantly more secret than nonsecrets. Thus, children acquire the implicit rules defining secret content from a somewhat later age than that reported for the cognitive or behavioral capacities for secrecy.     

The Destructive Path of Addiction: Experiences of Six Parents Who are Substance Dependent

This qualitative study explored the experiences of five men and one woman who were parents, substance dependent, and receiving treatment. Data collected by observation and in-depth interviewing were analyzed using constant comparison method and thematic analysis. Findings were grouped into three categories: surviving my childhood and becoming an adult, the struggles of trying to be a parent, and the roles of spouses and extended family members. An overarching metathematic category, the destructive path and powerful appeal of addiction, describes why the participants reported feeling most comfortable in the role of drug addict and found order in the chaos in the addictive lifestyle.     

Predicting early emotion knowledge development among children of colour living in historically disinvested neighbourhoods: consideration of child pre-academic abilities,self-regulation,peer relations and parental education

ABSTRACT

Emotion knowledge, the ability to accurately perceive and label emotions, predicts higher quality peer relations, higher social competence, higher academic achievement, and fewer behaviour problems. Less is known, however, about predictors of early development of emotion knowledge. This study examines emotion knowledge development among children attending pre-Kindergarten and Kindergarten programmes in high-poverty urban schools. The study considers child pre-academic abilities, self-regulation, peer relations and parental education as predictors of emotion knowledge development over two years. The sample (n?=?1034) of children living in historically disinvested neighbourhoods was primarily Black (85%) and low-income (～61%). The sample was part of a longitudinal follow-up study of a cluster (school) randomised controlled trial in ten public elementary schools. Children’s emotion knowledge was assessed with a series of tasks three times over a two-year period. At baseline, parents and teachers reported on peer relations, children completed a test of pre-academic abilities, independent observers rated child self-regulation, and parents reported on their educational attainment. Results demonstrate that emotion knowledge increases over time, and pre-academic abilities, self-regulation, peer relations, and parent education independently predict children’s emotion knowledge. This study highlights multiple factors that predict emotion knowledge among primarily Black children living in historically disinvested neighbourhoods.
