Children of incarcerated parents (COIP) are at risk for a range of negative outcomes; however, participating in a mentoring relationship can be a promising intervention for these youth. This study examined the impact of mentoring and mentoring program enhancements on COIP. Secondary data analyses were conducted on an archival database consisting of 70,729 matches from 216 Big Brothers Big Sisters (BBBS) local agencies to establish the differential effects of mentoring on COIP. A subset of 45 BBBS agencies, representing 25,252 matches, participated in a telephone interview about program enhancements for better serving COIP. Results revealed that enhanced program practices, including having specific program goals, providing specialized mentor training, and receiving additional funding resulted in better outcomes for COIP matches. Specifically, specialized mentor training and receiving additional funding for serving matches containing COIP were associated with longer and stronger matches. Having specific goals for serving COIP was associated with higher educational expectations in COIP. Results are discussed in terms of benefits of a relationship‐based intervention for addressing the needs of COIP and suggestions for program improvements when mentoring programs are serving this unique population of youth.  相似文献

Given that much of the research on classroom libraries focus on elementary school classrooms, this study sought to examine classroom libraries at the middle school level. Access to books is especially important for middle school students given the persistent decline in reading engagement at this level. The research questions guiding this investigation focused on the nature of the libraries, the physical features of the libraries, the contributions made by the libraries to the literacy environment of the classrooms, the contents of the libraries, and teacher perceptions of their own classroom libraries. Findings indicate that teachers value classroom libraries for promoting literacy engagement and understand how these libraries provide students with immediate and easy access to books. The contents of the libraries that were examined varied in terms of genre, multicultural literature, and social justice issues.  相似文献

Although emotion regulation deficits have been frequently implicated in the incidence of nonsuicidal self-injurious behavior (NSSI), no research to date has examined in vivo change of affect associated with real-world NSSI behavior. The present study employed Ecological Momentary Assessment (EMA) to assess change in affect associated with episodes of experienced NSSI in a sample of 36 college students with a self-reported history of NSSI. Results indicated that individuals who reported NSSI behavior over the course of the study experienced increases in negative affect prior to an episode of NSSI that peaked during the episode and faded gradually in the hours following the episode, with affect change roughly approximating a quadratic curve. These changes in affect were detected only at times in which individuals engaged in NSSI and were absent for individuals who did not report NSSI over the course of the study. Moreover, changes in negative affect associated with NSSI were, on average, detectable hours prior to the NSSI event. These findings suggest that episodes of NSSI may be predicted through a careful examination of affect change long before actual NSSI behavior occurs.  相似文献

This study examined pain sensitivity and pain modularity mechanisms (e.g., beta-endorphin levels, blood pressure) in women with premenstrual dysphoric disorder (PMDD; n = 27) and healthy controls (n = 27) during the follicular and luteal phases of the menstrual cycle. Physiological measures were taken during rest and ischemic pain testing. In both cycle phases, PMDD women (a) displayed lower resting cortisol and beta-endorphin levels and (b) exhibited shorter pain threshold and tolerance times and greater pain unpleasantness ratings during pain. PMDD women also reported greater pain unpleasantness and intensity and had lower beta-endorphin levels in their luteal phase and tended to display higher blood pressure levels at rest and during pain testing. Results suggest that endogenous opioids may be pathophysiologically relevant to PMDD and that the hypothalamic-pituitary-gonadal axis may modulate pain sensitivity in PMDD.  相似文献

The current study extends the literature on task interspersal (TI) by comparing the effects of four different TI ratios on the efficiency of skill acquisition and on levels of problem behavior in children with autism spectrum disorder and related disorders. The four ratios of TI were 3:1, 1:1, 1:3, and 0:1 mastered‐to‐acquisition tasks. An adapted alternating treatments design was implemented to compare the cumulative number of stimuli mastered, mean training time to mastery, rate of acquisition, and the level of problem behavior. The results showed that the 0:1 condition was the most efficient intervention procedure for all four participants. In addition, TI did not lead to a greater reduction in levels of problem behavior.  相似文献

When analyzing categorical data, it is often important to assess the magnitude of variation, or consensus, among observations in unordered categories. Utilizing the theory of partitions, exact solutions for five commonly used measures of categorical variation are presented. When the number of partitions is very large, resampling methods provide close approximations to exact probability values.  相似文献

A recent trend in the psychological literature has been to include measures of effect size when reporting probability values. The several measures of effect size associated with the Student t test for two independent samples are appropriate only when the variances are homogeneous. In this paper, commonly used measures of effect size are considered and compared, using four data sets. A chance-corrected measure of effect size is provided for two or more treatment groups characterized by either homogeneous or heterogeneous variances.  相似文献

The present study investigated whether trauma, stress, and discriminatory experiences influenced binge eating among 93 African American and 85 Caucasian women. Trauma and stress were significantly related to binge eating for both groups, although the stress- binge eating relationship was stronger for Caucasian women. Ethnicity did not moderate the relationship between trauma and binge eating, but did moderate the stress-binge eating relationship. Finally, the hypothesis that trauma and stress would influence binge eating through their effects on function of eating was partially supported; the relationship between stress and binge eating was partially mediated by function of eating among Caucasian women. The implications of these findings for our understanding of binge eating are discussed.  相似文献

This paper uses data from a national survey of adolescent Internet users (N = 1,501) to describe online relationships. Fourteen percent of the youths interviewed reported close online friendships during the past year, 7% reported face-to-face meetings with online friends, and 2% reported online romances. Two hundred forty-six youths provided details about one close online relationship. Most of these relationships were with same-age peers (70%) and crossed gender lines (71%). Many intersected with face-to-face social networks because they were initiated by introductions from friends or family (32%), involved people who lived in the vicinity (26%), were known to parents (74%), included offline contact by mail or telephone (70%), or involved face-to-face meetings (41%). Few youths reported bad experiences with online friends.  相似文献
