Measuring Anhedonia in Adolescents: A Psychometric Analysis

Anhedonia—the reduced capacity to experience pleasure—is a trait implicated in mental and physical health. Yet, psychometric data on anhedonia measures in adolescents are absent. We conducted an in-depth psychometric analysis of the Snaith–Hamilton Pleasure Scale (SHAPS; Snaith et al., 1995 Snaith, R. P., Hamilton, M., Morley, S., Humayan, A., Hargreaves, D., & Trigwell, P. (1995). A scale for the assessment of hedonic tone: The Snaith–Hamilton Pleasure Scale. British Journal of Psychiatry, 167, 99–103. doi:10.1192/bjp.167.1.99[Crossref], [PubMed], [Web of Science ®] , [Google Scholar])—a self-report measure of anticipated pleasure response to 14 pleasant experiences—in adolescents. Adolescents (N = 585, M age = 14.5) completed the SHAPS and other paper-and-pencil surveys. Item response theory models were used to evaluate the psychometric performance of each SHAPS item. Correlations of the SHAPS with other personality and psychopathology measures were calculated to evaluate construct validity. Results showed that (a) certain items (e.g., reported pleasure from basic experiences like “seeing smiling faces” or “smelling flowers”) provided more information about latent anhedonia than others; and (b) SHAPS scales exhibited construct-consistent convergent and discriminant validity (i.e., stronger correlations with low positive affect constructs, weaker correlations with negative affect). Reporting diminished pleasure from basic pleasant experiences accurately indicates adolescent anhedonia, which is important for future scale development and understanding the phenomenology of anhedonia in teens. These data support using the SHAPS for assessing anhedonia in epidemiological research and school-based universal prevention programming in general adolescent populations.     

Extracurricular Participation and Course Performance in the Middle Grades: A Study of Low-Income,Urban Youth

The transition to middle/junior high school is associated with declines in students’ academic performance, especially among low‐income, urban youth. Developmental psychologists posit such declines are due to a poor fit between the needs of early adolescents—industry, identity, and autonomy—and the environment of their new schools. Extracurricular participation during these years may act as a buffer for youth, providing a setting for development outside the classroom. The current study examines participation within and across activity settings among low‐income, urban youth in New York City over this transition. Using the Adolescent Pathways Project data, this study explores how such participation relates to course performance. We find that a large percentage of youth are minimally or uninvolved in extracurricular activities during these years; that participation varies within youth across time; and that the association between participation and course performance varies by activity setting. Youth who participate frequently in community or athletic settings or have high participation in two or more settings are found to have higher GPAs in the year in which they participate and youth who participate frequently in the religious setting are found to have lower GPAs. High participation in more than two settings may be detrimental.     

On becoming textually active at Youthline,New Zealand

The phones hardly ring at Youthline New Zealand anymore; youth still have problems and seek help, but it mostly happens silently. This article reports on experiences of texting at a 24-hour crisis helpline for young people. To date, there has been no formal evidence base for this practice; however, for new practice, there never is. In prompting discussion, this article attends to the tight constraints that texting imposes, returning to the necessary and sufficient conditions of any effective therapeutic relationship particularly in regard to working with young people. New possibilities are demonstrated with emotional support being demonstrated even in the tightly constrained space of a text-based medium.     

Evaluating the Psychometric Properties of the Teamwork KSA Test

The Teamwork KSA Test has been a welcome addition to the practitioner's selection toolkit as well as a useful measure for teamwork researchers. We analyzed the psychometric properties of the Teamwork KSA Test and recognized correlates of the construct using three samples of working individuals recruited through a university (N = 241, N = 230, N = 332) and found slim evidence for a factor structure of the underlying constructs. Furthermore, classical reliability estimates did not meet traditional psychometric standards. Total TKSA scores predicted self‐ratings and instructor ratings of teamwork in two of the samples; effect sizes were small.     

Longitudinal trajectories of bicultural identity integration in recently immigrated Hispanic adolescents: Links with mental health and family functioning

This study examined, in a sample of recently immigrated Hispanic adolescents in Miami and Los Angeles, the extent to which bicultural identity integration (BII; involving the ability to synthesise one's heritage and receiving cultural streams and to identify as a member of both cultures) is best understood as a developmental construct that changes over time or as an individual‐difference construct that is largely stable over time. We were also interested in the extent to which these trajectories predicted mental health and family functioning. Recent‐immigrant 9th graders (N = 302) were assessed 6 times from 9th to 12th grade. Latent class growth analyses using the first 5 timepoints identified 2 trajectory classes—one with lower BII scores over time and another with higher BII scores over time. Higher heritage and US identity at baseline predicted membership in the higher BII class. At the 6th study timepoint, lower BII adolescents reported significantly poorer self‐esteem, optimism, prosocial behaviour and family relationships compared with their higher BII counterparts. These findings are discussed in terms of further research on the over‐time trajectory of biculturalism, and on the need to develop interventions to promote BII as a way of facilitating well‐being and positive family functioning.     

Residential mental health assessment within Dutch criminal cases: a discussion

In Dutch criminal cases in which doubts arise about the defendant's mental health, a forensic assessment will be requested. This is provided either by the multidisciplinary staff of residential clinics who conduct forensic evaluations for the court, or by mental health professionals contracted on a part-time basis by district courts. This article discusses the procedures applied in such cases as well as the relevant legal provisions. It focuses particularly on the clinical observation, evaluation, and reporting that is carried out over a number of weeks in the residential setting of the Pieter Baan Centrum. Specific attention is paid to procedures applied in this clinic. It is suggested that Dutch procedures for the use of mental health expertise can best be characterized by three aspects: multidisciplinary observation and reporting, the use of a sliding scale for indicating degree of responsibility, and, finally, the involvement and payment of experts by the state as such, rather than by the prosecution and/or the defense.

Children's use of frequency information for trait categorization and behavioral prediction

Two experiments examined young children's use of behavioral frequency information to make behavioral predictions and global personality attributions. In Experiment 1, participants heard about an actor who behaved positively or negatively toward 1 or several recipients. Generally, children did not differentiate their judgments of the actor on the basis of the amount of information provided. In Experiment 2, the actor behaved positively or negatively toward a single recipient once or repeatedly. Participants were more likely to make appropriate predictions and attributions after exposure to multiple target behaviors and with increasing age. Overall, children's performance was influenced by age-related positivity and negativity biases. These findings indicate that frequency information is important for personality judgments but that its use is affected by contextual complexity and information-processing biases.     

Popularity, social acceptance, and aggression in adolescent peer groups: links with academic performance and school attendance

This article reports a short-term longitudinal study focusing on popularity and social acceptance as predictors of academic engagement for a sample of 342 adolescents (approximate average age of 14). These youths were followed for 4 consecutive semesters. Popularity, social acceptance, and aggression were assessed with a peer nomination inventory, and data on academic engagement were obtained from school records. For adolescents who were highly aggressive, increases in popularity were associated with increases in unexplained absences and decreases in grade point average. Conversely, changes in social acceptance were not predictive of changes in grade point average or unexplained absences. These results highlight the importance of multidimensional conceptualizations of social standing for research on school adjustment during adolescence and emphasize the potential risks associated with popularity.
