Robustness without rank order statistics

An alternative to conventional rank tests based on a Euclidean distance analysis space is described. Comparisons based on exact probability values among classical two-sample t-tests and the Wilcoxon–Mann–Whitney test illustrate the advantages of the Euclidean distance analysis space alternative.     

Traditional Gift Giving Among Pacific Families in New Zealand

The Pacific population in New Zealand is socially disadvantaged and over-represented in adverse social and health statistics. A cohort of 1,376 mothers of Pacific infants were asked about traditional gift commitments and the effect that these commitments had on the financial situation in their household. Sixty-two percent reported that they and/or their partner usually gave to their family or church, with 66.5% of this group giving to family in New Zealand, 58% to family in the Pacific Islands, and 75.9% to their church. Fifty-nine percent of these mothers reported that this gift commitment made their household financial situation more difficult. Factors significantly associated with gift giving are discussed, together with implications of these findings for Pacific families living New Zealand.     

Nonsuicidal Self-injury in a College Population: General Trends and Sex Differences

Abstract

Objective: To describe basic nonsuicidal self-injury (NSSI) characteristics and to explore sex differences. Methods: A random sample from 8 universities were invited to participate in a Web-based survey in 2006–2007; 38.9% (n = 14,372) participated. Analysis assessed sex differences in NSSI prevalence, practices, severity, perceived dependency, and help-seeking; adjusted odds ratios for NSSI characteristics were calculated by sex status. Results: Lifetime NSSI prevalence rates averaged 15.3%. Females were more likely than males to self-injure because they were upset (adjusted odds ratio [AOR] = 1.6; 95% confidence interval [CI] = 1.3–2.1) or in hopes that someone would notice them (AOR = 1.6, 95% CI = 1.1–2.7). Males were 1.6 times (95% CI = 1.2–2.2) more likely to report anger and 4.0 times (95% CI = 2.3–6.8) more likely to report intoxication as an initiating factor. Sexual orientation predicted NSSI, particularly for women (Wald F = 8.81, p ≤ .000). Only 8.9% of the NSSI sample reported disclosing NSSI to a mental health professional. Conclusions: NSSI is common in college populations but varies significantly by sex and sexual orientation. NSSI disclosure is low among both sexes.     

Response adaptive designs that incorporate switching costs and constraints

This paper examines the design and performance of sequential experiments where extensive switching is undesirable. Given an objective function to optimize by sampling between Bernoulli populations, two different models are considered. The constraint model restricts the maximum number of switches possible, while the cost model introduces a charge for each switch. Optimal allocation procedures and a new “hyperopic” procedure are discussed and their behavior examined. For the cost model, if one views the costs as control variables then the optimal allocation procedures yield the optimal tradeoff of expected switches vs. expected value of the objective function.     

Cultural,individual, and familial risk and protective factors associated with depressive symptoms in Pacific youth living in New Zealand

ABSTRACT

This article examines cultural, individual, and familial risk and protective factors associated with depressive symptoms in Pacific youth living in New Zealand. At ages 11 (n = 950) and 14 (n = 931), Pacific youth participated in multidisciplinary interviews that included the Children’s Depression Inventory. Across time points, factors significantly associated with higher depressive symptoms were involvement in bullying and gang activities. Positive parenting was significantly associated with lower depressive symptoms, and Tongan youth were significantly less likely to report depressive symptoms than Samoan youth. Time-varying factors were gender, problem behaviour syndromes, and maternal education. Gaining more knowledge about modifiable risk and protective factors that contribute to depression in Pacific youth is an important tool to support new approaches that promote adaptive psychological adjustment during adolescence.     

Toward Trauma-Informed Career Counseling

The Adverse Childhood Experiences study (Felitti et al., 1998) showed that early adversity can have a profound lifelong effect on personal development, social relationships, coping methods, and career trajectories. The authors review critical findings related to trauma-informed counseling practices, discuss literature linking trauma and career theories, and consider how career counseling could address the effects of adverse childhood experiences using trauma-informed practices. An integration of trauma-informed practices with career counseling using narrative and other approaches is proposed. The proposed integration holds implications for incorporating trauma-informed practice in career counselor preparation programs and in career counseling practice.
