Samoan adolescents in American Samoa and Hawaii: Comparison of youth violence and youth development indicators: A study by the Asian/Pacific Islander Youth Violence Prevention Center

Samoan youths are critically under-studied in research on youth violence prevention and adolescent development. When Samoan adolescents are included in research investigations, they are typically obscured into the much larger aggregated categories of “Pacific Islanders” or “Asian Americans and Pacific Islanders.” The present study is one of the first to examine Samoans exclusively and compare the differences between Samoan youths residing in American Samoa and those residing in Hawaii. In an effort to gauge the acculturative processes of adolescents in American Samoan and Hawaii, the present study compared these two groups' self-reports of violence, substance use, grade-point average, scholastic aspirations, importance of religion, ethnic identity, parenting discipline style, and family support. Overall, the results indicated higher rates among Samoan adolescents in Hawaii as compared to those in American Samoa on one violence item and on substance use indicators (i.e., alcohol and marijuana). Samoan adolescents in American Samoa also reported higher levels of protective factors related to the importance of religion (especially for girls), ethnic identity, and family support. However, Samoan adolescents in Hawaii had higher scholastic aspirations than those in American Samoa, despite having lower grade-point averages. In general, Samoan students who did not self-report engaging in violence had higher rates of protective factors as compared to those who indicated engaging in violence. Statistically significant interactions reflected more complex effects. The implications of these findings in conjunction with the results of the Youth Risk Behavior Survey (YRBS) are discussed in the context of Samoan culture, acculturation, and youth development.     

The time course of attentional and oculomotor capture reveals a common cause

Eye movements are often misdirected toward a distractor when it appears abruptly, an effect known as oculomotor capture. Fundamental differences between eye movements and attention have led to questions about the relationship of oculomotor capture to the more general effect of sudden onsets on performance, known as attentional capture. This study explores that issue by examining the time course of eye movements and manual localization responses to targets in the presence of sudden-onset distractors. The results demonstrate that for both response types, the proportion of trials on which responses are erroneously directed to sudden onsets reflects the quality of information about the visual display at a given point in time. Oculomotor capture appears to be a specific instance of a more general attentional capture effect. Differences and similarities between the two types of capture can be explained by the critical idea that the quality of information about a visual display changes over time and that different response systems tend to access this information at different moments in time.     

Anxiety sensitivity, conscious awareness and selective attentional biases in children

The current study investigated whether physical anxiety sensitivity (AS) is associated with selective attentional biases to affective stimuli in children. The dot-probe paradigm was used to examine the deployment of attention towards words pertaining to anxiety symptomatology, socially threatening words, and positive words, in samples of 8-10-year-old children. Word pairs were presented under both masked and unmasked conditions. Irrespective of masking, children high in physical AS displayed an attentional vigilance for emotional words relative to neutral words, whereas those low in physical AS displayed a relative avoidance of such material. The results of this study are interesting as they not only suggest the presence of automatic AS-related biases in childhood, but that this is a general emotionality bias rather than one related to specific anxiety-related stimuli.     

Identifying the Developmental Strengths of Juvenile Offenders: Assessing Four Life‐Skills Dimensions

The authors describe the development of the Life‐Skills Development Scale Juvenile Form, a brief self‐report instrument for assessing the life‐skills development of juvenile offenders. Reliability and validity findings are presented, implications for treatment planning are provided, and recommendations for further research are discussed.     

Conceptualizing the Influence of Social Agents of Behavior Change: A Meta-Analysis of the Effectiveness of HIV-Prevention Interventionists for Different Groups

A meta-analysis of 166 HIV-prevention interventions tested theoretical predictions about the effects of experts, lay community members, and similar and dissimilar others, as agents of change. In general, expert interventionists produced greater behavior change than lay community members, and the demographic and behavioral similarity between the interventionist and the recipients facilitated behavioral change. Equally importantly, there were differences across groups in the efficacy of various sources, especially among populations of low status and/or power. These findings support the hypothesis that unempowered populations are more sensitive to characteristics of the interventionists who can facilitate access to various resources. In addition, they suggest the need to ensure the availability of health professionals from diverse demographic and behavioral backgrounds.     

The Abbreviated Math Anxiety Scale (AMAS): construction,validity, and reliability

Psychometric properties of mathematics anxiety measures have not adequately been studied. Using a large sample size (N = 1,239), the authors developed an abbreviated math anxiety measure, examined its psychometric properties, and assessed the generalizability of the model across samples. Exploratory factor analysis yielded a nine-item measure and strong internal consistency, test-retest reliability, and good convergent/divergent validity was demonstrated with an independent sample. When administered to a replication sample, indexes suggested an excellent model fit. TheAbbreviated Math Anxiety Scale (AMAS) may represent a more parsimonious and valid approach to assess mathematics anxiety.     

Anxiety sensitivity: the role of conscious awareness and selective attentional bias to physical threat

Selective attentional biases were examined amongst individuals varying in levels of physical anxiety sensitivity. The dot-probe paradigm was used to examine attention towards anxiety symptomatology, social threat and positive words. Stimuli were presented above (unmasked) and below (masked) the level of conscious awareness. High physical anxiety sensitivity was associated with attentional vigilance for anxiety symptomatology words in both unmasked and masked conditions. For positive words, however, those high in anxiety sensitivity were found to avoid such stimuli when they were masked, whereas they exhibited a relative vigilance when unmasked. If the differences between awareness conditions are reliable, then the impact of the automatic vigilance for threat might be modified by conscious attempts to direct attention towards other types of stimuli.
