The Impact of Mother Support and Natural Mentoring on the Depressive Symptoms of Black Youth

Research indicates both natural mentoring and family factors such as parental support are beneficial for the psychological wellbeing of youth. Despite the existing evidence on the benefits of natural mentoring and parental support, there has been little evidence that considers the simultaneous influence of these factors on the depressive symptoms among Black youth. Guided by Keller’s systemic model of mentoring, we investigated the influence of mother support and the characteristics of natural mentoring relationships on depressive symptoms among Black youth. We used nationally representative data of Black youth from the National Longitudinal Study of Adolescent Health (N?=?2344). The findings indicate that both mentor bonding and mother support were significant predictors of depressive symptoms among Black youth. However, mother support was positively associated with depressive symptoms and mentor bonding was negatively associated with depressive symptoms. The findings highlight the importance of natural mentors in the lives of Black youth and suggest they may be useful in alleviating depressive symptoms.

     

Training Pediatric Psychologists for Perinatal Behavioral Health Services in a Pediatric Hospital

Although pediatric hospitals specialize in providing care to children and adolescents, at The Children’s Hospital of Philadelphia (CHOP), our team has been providing behavioral health services for two unique parent populations—parents with a child in the Newborn Infant Intensive Care Unit and pregnant women carrying fetuses with specific birth defects and receiving prenatal care in the Center for Fetal Diagnosis and Treatment. A new training program was developed to expand the scope of pediatric psychologists’ practice to include perinatal behavioral health services, specifically for these two unique parent populations served at CHOP. The program includes direct service provision for adult mental health concerns, as well as education and support to help families cope with the existing medical conditions. This article describes the training program and its implementation as a model of training for other pediatric hospitals. The roles of psychologists embedded in these units and hospital privileges are discussed.     

It's more than skin‐deep: The relationship between social victimization and telomere length in adolescence

This study examined the relationship between peer victimization and telomere length (TL), an indicator of biological aging that is associated with stressors (Epel, 2009). It was predicted that social victimization would have a greater impact upon TL, as well as the frequency and severity of health complaints than physical victimization. Adolescents (M_age = 15.91 years, SD_age = 1.65) and their parents completed measures of peer victimization and physical health problems; adolescents also submitted a DNA sample for telomere analysis. Greater instances of being socially, but not physically, victimized were associated with shorter telomeres, as well as more frequent and severe health complaints. TL was also negatively related to both the frequency and severity of health problems, even after controlling for BMI, age, and sex of participant. The relationship between social victimization and health complaints via TL held only at higher levels of social victimization. These findings are the first to find an association between peer victimization and shortened telomeres.

     

Development and Validation of the Personal Values Dictionary: A Theory-Driven Tool for Investigating References to Basic Human Values in Text

Estimating psychological constructs from natural language has the potential to expand the reach and applicability of personality science. Research on the Big Five has produced methods to reliably assess personality traits from text, but the development of comparable tools for personal values is still in the early stages. Based on the Schwartz theory of basic human values, we developed a dictionary for the automatic assessment of references to personal values in text. To refine and validate the dictionary, we used Facebook updates, blog posts, essays, and book chapters authored by over 180 000 individuals. The results show high reliability for the dictionary and a pattern of correlations between the value types in line with the circumplex structure. We found small to moderate (r_s = .1–.4) but consistent correlations between dictionary scores and self-reported scores for 7 out of 10 values. Correlations between the dictionary scores and age, gender, and political orientation of the author and scores for other established dictionaries mostly followed theoretical predictions. The Personal Values Dictionary can be used to assess references to value orientations in textual data, such as tweets, blog posts, or status updates, and will stimulate further research in methods to assess human basic values from text.     

Psychometric validity of proration and Digit Span substitution for estimating WISC--R verbal and Full Scale IQs

This study investigated the merits of substituting the Digit Span subtest for an invalid Verbal Scale subtest versus a proration method in calculating WISC--R Verbal and Full Scale IQ. Subjects were 93 child and adolescent psychiatric patients (67 boys and 26 girls) who ranged in age from 8 to 16 yr. Analysis indicated that the use of Digit Span as a substitute for the regularly administered Verbal subtests was inferior to the use of the comparable proration method. Although relatively few cases of misclassification occurred for either method in relation to Full Scale IQ, the rate of Verbal IQ misclassification by the Digit Span substitution method was significantly greater than with use of its proration. When faced with a choice, clinicians should attach greater validity to prorated estimates of a child's WISC--R Verbal IQ.     

Trees with structure

We investigate M-trees, that is, trees with structure possible at each node or level. M is a mathematical structure such as a set or a Cartesian product. An extension of Pólya's theorem is proved which allows the number of M-trees for a given number of nodes to be counted. The special case of componential trees is investigated. Here M is a Cartesian product of 0's and 1's. A componential analysis is a componential tree of depth 1, that is, there is no hierarchy. We prove that for any componential tree there exists a componential analysis which makes the same predictions on a triad test of judged similarity. A brief empirical example is given, in which a componential tree is applied as a model of a sernantic domain.
