Persons referred by Child Protective Services (CPS) for substance abuse evidence high rates of nonattendance to therapy sessions, taxing systems of care and exacerbating outcomes. This study examined the influence of two telephone-based incentive programs on therapy session attendance in mothers who were referred by CPS for substance abuse. After baseline therapy session attendance was established in an evidence-based clinic that incorporated a telephone engagement intervention (Phase I), participants were provided free cellular telephones with limited minutes and permitted to order free meals delivered by the therapist during upcoming sessions (Phase II). The third phase was similar to Phase II, but participants were provided unlimited minutes. Results indicated that participants’ attendance was significantly improved when meals and cellular telephone minutes were contingent on attendance. Although the percentage of sessions attended by participants during Phase III was higher than Phase II, unlimited minutes and meals did not significantly enhance attendance relative to limited minutes and meals. Session attendance for significant others of these participants was significantly higher during Phase III as compared with Phase I. Session attendance of significant others was statistically similar between Phase I and II and between Phase II and Phase III. Study implications and recommendations for future research and practice are discussed in light of the findings.  相似文献

Urbanization and other land cover changes have been particularly detrimental to wetlands throughout the planet. One wetland specialist that may be sensitive to land cover changes surrounding wetlands is the round-tailed muskrat (Neofiber alleni; hereafter RTM). The RTM is a wetland obligate rodent that appears to have declined over the last half century and is a species of concern in Florida, where it is a near endemic. To determine if urbanization or other land cover influenced the distribution of RTMs we took a multi-scaled approach to examine the occurrence of RTMs and their associated vegetation in North-Central Florida. We detected RTMs on 19 of 72 sample plots and used a Classification And Regression Tree (CART) to determine that dogfennel (Eupatorium capillifolium) was negatively associated with RTMs and maidencane (Panicum hemitomon) was positively associated with their occurrence on sampling plots. Examining the influence of landscape composition for 2 km surrounding our plots we found that RTM occurrence was negatively related to urban land cover. Further, we found that dogfennel increased and maidencane decreased as urbanization increased in the surrounding landscape. Our research suggests that conservation of RTMs and their associated vegetation should focus on limiting urban sprawl at least within 2 km of wetlands.  相似文献

This paper considers procedures for the detection of heteroscedasticity when it occurs at unknown points. First the number of points is assumed known apriori and then this assumption is relaxed so that both the position and the number of possible aberrant observations is unknown. Monte Carlo evidence is provided on the performance of both tests and they are found to perform reasonably.  相似文献

This article reviews the literature on the psychological consequences of dieting. In particular, the authors examine the impact of dieting on mood, self-esteem, cognition, and eating behavior. The famous Keys study of starvation is discussed in relations to impaired concentration, food preoccupation, negative affect, and binge eating behavior. Overall, the literature indicates that dieting has a negative impact on psychological well-being. As a result, alternative nondieting approaches toward eating are presented and recommended to promote psychological health.  相似文献

This study examined mother–child acculturation gaps in relationship to youth distress and the possible mediating role of parent–child conflict and parenting style in a sample of 81 Chinese American families. Hierarchical multiple regression analyses provided partial support for a relationship between acculturation gaps and youth distress. No mediators of this relationship were found; however, post-hoc analyses indicated that intergenerational conflict and parenting style were associated with youth distress above and beyond acculturation gaps. These results suggest that interventions developed to reduce parent–child conflict and increase parental bonding (increase parental warmth and decrease parental overprotection) may be valuable for Chinese American adolescents, regardless of acculturation gap status.  相似文献

Objective. Survey research consistently reports a positive association between educational attainment and socially tolerant attitudes, but critics hold that respondents with high levels of education may simply purport to hold attitudes seen as socially desirable. In this article, we seek to adjudicate between the claim that the association between education and social tolerance is simply an artifact of sophisticated social desirability reporting on the part of well‐educated respondents and the competing theory that education has a real impact on increasing forms of social tolerance. Methods. Using support for a black presidential candidate as our measure of social tolerance, we utilize an innovative online list experiment to test whether high levels of support are inflated because of social desirability reporting among the educational elite. Results. We find no evidence of systematic overreporting of support for a black presidential candidate among respondents with high levels of education, and note that social desirability bias declines as educational attainment increases. Conclusions. This research bolsters arguments about the liberalizing effect of education on socially tolerant attitudes, and challenges evidence that attributes this relationship to high levels of social desirability bias.  相似文献

This paper places friendships at the center of individuals' identity work, examining how individuals construct self‐identities through their talk about friend relationships and networks. We conceptualize this “friendship talk” as a subcategory of identity talk. From interviews with emerging adults, we find three strategies of friendship talk: envisioning self through others, betterment distancing, and situating with networks. These strategies demonstrate unique ways identity construction occurs through talk about friends. Individuals verbally connect with and separate from friends while constructing desired selves and moral identities. We suggest that friendship talk strategies may be generic social processes that apply beyond emerging adulthood.  相似文献
