The high prevalence of depression among incarcerated youth indicates a need to better understand factors that contribute to depression within this vulnerable subgroup. Previous research in general community samples has suggested that high levels of stress and low levels of parental support are associated with depression in young people, but it is unclear whether or how they might be associated with depression among incarcerated youth who are already vulnerable. Using a sample of 228 adolescents (aged 13–18 years) who were detained in the juvenile justice system, stress and support were modeled as independent main effects and as interactive risk factors in relation to depressive symptoms. More stressful life events and less caregiver support were each independently associated with depressive symptoms, but no evidence was found for the buffering hypothesis in this sample. Stressful life events were more strongly associated with depressive symptoms among boys compared to girls.  相似文献

The purpose of the current study was to examine the relative contributions of weight status, race/ethnicity, sex, and age on body dissatisfaction in a large group of diverse children. Participants were 4th–6th graders (N = 1212) in ten inner-city schools who participated in an obesity prevention study previously published. Children completed the body dissatisfaction subscale of the Eating Disorder Inventory-2 (EDI-2), and weight status was assessed by measured weights and heights. Multiple regression analyses were conducted. Relative weight status was the strongest predictor of body dissatisfaction, followed by race/ethnicity, and sex. Body dissatisfaction was greatest in obese, Asian, and female children. Overall, results indicated that children's body dissatisfaction varies based on relative weight status, as well as race/ethnicity and sex among urban children. Results highlight the strong need for additional research so that more definitive conclusions may be drawn regarding the development of body image among diverse groups of children.  相似文献

Youth with elevated conduct disorder (CD) symptoms who also have callous-unemotional (CU) traits exhibit more antisocial behavior than youth without CU traits. However, evidence regarding whether CU traits increase risk of substance use over and above CD symptoms, and whether these associations differ for boys and girls, is scarce. Using the Developmental Pathways Project sample of 521 middle school students, we examined whether adolescent- and parent-reported CU traits measured in 6th grade prospectively predicted the onset and recurrence of substance use and use-related impairment by 9th grade. We also examined the degree to which CU traits uniquely predicted substance use and impairment over and above CD symptoms, as well as whether gender moderated these associations. Results indicated that adolescent-reported CU traits increased the likelihood of substance use and impairment onset and recurrence by 9th grade. Analyses revealed that CD symptoms accounted for prospective associations between adolescent-reported CU and substance use, but gender moderated these associations. Boys with elevated CU traits and CD symptoms were not more likely to report alcohol use onset or recurrence, but they were at highest risk of recurrent marijuana use, use of both alcohol and marijuana, and use-related impairment by 9th grade. Girls with low CU traits and high CD symptoms were most likely to report onset and recurrent use of alcohol, as well as recurrent marijuana use, use of both substances and impairment. Study findings highlight the importance of accounting for CD symptoms and gender when examining links between CU traits and substance use in early adolescence.  相似文献

There is a large body of evidence relating to the ways that people tap in time with sounds, and perform error correction in order to do this. However, off-beat tapping is less well investigated than on-beat tapping. The current study involves coordinating with a stimulus sequence with underlying isochrony and systematic deviations from this isochrony that increase or decrease in magnitude to look at people’s capacity to error-correct when performing off-beat synchronisation with a set of sounds. Participants were instructed to ‘tap between the tones’ but ‘try to maintain regularity’. While analysis using typical methods suggested a form of error correction was occurring, a series of more complex analyses demonstrated that participants’ performance during each trial can be classified according to one of four different strategies: maintaining a regular pulse, error correction, phase resetting, and negative error correction. While maintaining a regular pulse was the preferred strategy in conditions with increasingly isochronous stimuli, the majority of trials are best explained by other strategies, suggesting that participants were generally influenced by variability in the stimuli.  相似文献

The complex and dynamic nature of systems pose a particular challenge to researchers and require the use of a research methodology designed to deal with such systems. The properties of fit, relevance, understandability, generality, control, workability, generalizability, and modifiability make Glaserian grounded theory and grounded action particularly well suited for studying systems. These methods are innovative, systemic, and sophisticated enough to reveal the underlying complexities of systems and plan actions that address their complex, dynamic nature while remaining grounded in what is occurring within the systems as they change over time.  相似文献

This study investigates the discriminant validity of a measure of attitudes toward male roles, i.e., beliefs about the importance of men adhering to cultural defined standards for masculinity. Using data from the 1988 National Survey of Adolescent Males, the Male Role Attitude Scale (MRAS) is evaluated in terms of (1) its independence from measures of attitudes toward female roles, and of attitudes toward gender roles and relationships, and (2) its differential correlates with and incremental ability to explain variance in criterion variables compared to measures of these two other gender-related attitudes. As predicted, the MRAS is unrelated to attitudes toward the female role, but is significantly associated with attitudes toward gender roles and relationships. As further predicted, the MRAS, but not attitudes toward women or attitudes toward gender roles and relationships, is associated with homophobic attitudes toward male homosexuality and with traditional male procreative attitudes. In addition, the MRAS explains significant incremental variance in these criterion measures when attitude toward female roles and attitude toward gender roles and relationships are controlled for. These results support the theoretical argument that attitudes toward male roles are conceptually distinct from the other gender-related attitudes examined here.This research was supported by grants from the National Institute of Child Health and Human Development and from the Office of Adolescent Pregnancy Programs.

Measuring a program's success in enabling a child to improve functioning at home, school, and the community requires careful tracking of children's progress during the intervention and after it is completed. Attrition is often a major problem in carrying out longitudinal research. I present a number of strategies for maintaining high rates of response in follow-up studies, including how to choose a study design that enhances participation, how to locate study participants, how to engage study participants, and how to select and train high quality interviewers. The strategies presented have been used with success by a children's mental health agency and may be helpful to other researchers as they evaluate programs, measure outcomes, and study the life course of children with mental illness.  相似文献
