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.     

A Longitudinal Test of the Job Demands‐Resources Model among Australian University Academics

A longitudinal test of the Job Demands‐Resources (JD‐R) model of work stress and engagement ( Bakker & Demerouti, 2007 ; Demerouti et al., 2001 ) was conducted in a sample of Australian university academics (N= 296). The aim was to extend the JD‐R model by (1) determining how well job demands (work pressure, academic workload) and job resources (procedural fairness, job autonomy) would predict psychological strain and organisational commitment over a three‐year period, and (2) incorporating longitudinal tests of reversed causation. The results of SEM analyses showed that Time 1 resources directly predicted Time 2 strain and organisational commitment, but that Time 1 demands predicted Time 2 strain only indirectly via job resources. We did not find evidence for reversed causation. We discuss possible mediators of the relationships between working conditions and work stress outcomes, and the practical implications of the results.     

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.

     

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.

     

Reduced Verbal Memory Retention is Unrelated to Sleep Disturbance During Pregnancy

This study investigated episodic and procedural memory retention in early and late pregnancy and whether memory retention was related to sleep disruption. Twenty‐six women in the third trimester of pregnancy, 20 women in the first trimester of pregnancy, and 24 non‐pregnant controls were administered a battery of verbal and visual episodic memory tasks and two procedural memory tasks before undergoing an overnight sleep study. Memory retention was assessed the following morning. Results indicated that as compared with controls, both pregnant groups had reduced retention in verbal episodic memory but were unimpaired on visual and procedural memory tasks. The pregnant women also demonstrated significant disruption of sleep patterns. Reduced verbal memory retention during pregnancy was not attributable to any measure of sleep; however, small correlations between some indices of sleep and memory do not allow full dismissal of the sleep‐dependent memory consolidation hypothesis.     

Obsessive-Compulsive Disorder in the Media

Scholars have long been concerned that mass media depictions of those with mental disorders foster stigma. Research is needed extricating how particular disorders are represented and perceived, such as obsessive-compulsive disorder (OCD). This article examines what images of obsessions and compulsions exist in the media, and how persons interpret these. It employs two methods: qualitative in-depth interviews and content analysis. Data indicate the media represents obsessions and compulsions in distinguishable ways that both reinforce and complicate common media stereotypes of those with mental disorders—fostering a stigma hierarchy and having contradictory effects on mental health literacy.
