Data from two multi-ethnic prospective studies of African American, Latina, and non-Hispanic White pregnant women were used to examine the influence of contextual factors on social support processes during pregnancy. Multiple types of support (perceived support, received support, support satisfaction, network support) and sources of support (baby's father, family, friends) were assessed. The role of ethnicity in social support was examined after controlling for the contribution of related contextual factors (SES, marital status, age, parity, employment) to these processes. The impact of ethnicity and related contextual factors differed across sources of social support. Ethnic differences in support from family and friends, but not from the baby's father, emerged. However, marital status was a consistent predictor of support from the baby's father, and SES was a consistent predictor of support from friends. Overall, the findings of two studies suggest that although ethnicity is associated with support from friends and family, other contextual factors, such as marital status and SES, influence support processes during pregnancy. 相似文献

The functional role of NCAM gene expression in memory formation was studied in the one-trial passive avoidance task in day-old chicks by pretraining injections of one of three different 18-mer end-protected oligonucleotides corresponding to positions 190-, 207-, and 332- of the NCAM Ig1 domain. Twenty-four-hour-old chicks were trained by pecking at a bitter-tasting bead and tested for avoidance 30 min, 3, 8, or 24 hr later. Memory retention was significantly reduced only in the group of animals injected with the NCAM antisense corresponding to position 207- (AS-ODN-207), and only if given twice, both immediately after hatching and 12 hr before training. This antisense was without effect on the general behavior of the chicks, training or acquisition, and did not produce observable neurotoxic damage. Under such conditions amnesia was evident by 3 hr after training and lasted until at least 24 hr after training. The two other tested oligonucleotides were without behavioral effect. To control for nonsequence-specific effects of AS-ODN-207, brains from injected and trained animals were processed for Western blotting and probed using anti-NCAM, anti-L1, and anti-actin antibodies. NCAM antisense corresponding to position 207- significantly reduced the level of NCAM, whereas the level of L1 and actin remained unchanged. These results confirm our earlier conclusion that NCAM is necessary for longer term memory retention. 相似文献

Self-Efficacy as a Mediator of Caregiver Coping: Development and Testing of an Assessment Model 总被引:1,自引:0,他引:1

Development and utilization of two self-efficacy measures thought to be relevant to stressed family caregivers, Caregiver Self-Care Self-Efficacy and Caregiver Problem-Solving Self-Efficacy, are described. Data obtained in the context of a psychoeducational intervention program are available for 217 caregivers of frail and/or cognitively impaired elders. Analyses of psychometric properties of the efficacy measures demonstrate good internal consistency and test-retest reliability for both measures. In addition, both measures of self-efficacy are related to depression as measured by the Beck Depression Inventory and caregiver distress as measured by the Zarit Burden Scale. Problem-Solving Self-efficacy also is related to subjective caregiver burden as measured by Zarit's Memory and Behavior Problem Checklist. Results are promising in terms of the utility of the measure and the application of self-efficacy theory to the caregiving situation. Limitations of these measures are discussed and suggestions made for improved second-generation self-efficacy scales. 相似文献

We compared the effects of reinforcing compliance with either positive reinforcement (edible items) or negative reinforcement (a break) on 5 participants' escape-maintained problem behavior. Both procedures were assessed with or without extinction. Results showed that compliance was higher and problem behavior was lower for all participants when compliance produced an edible item rather than a break. Treatment gains were achieved without the use of extinction. Results are discussed regarding the use of positive reinforcement to treat escape behavior. 相似文献

The authors evaluated a health careers program in a U.S. urban public high school. After small subgroups of the original sample were removed, participants included 162 Asian American and Pacific Islander students. Analyses of covariance indicated that, compared with the comparison group, the treatment group reported significantly higher levels of social support, school engagement, interest in learning, vocational expectations, and ethnic identity. Implications for multicultural counseling in schools are discussed. Los autores evaluaron un programa de carreras sanitarias en una escuela secundaria pública de Estados Unidos. Tras la eliminación de pequeños subgrupos de la muestra original, los participantes incluyeron 162 estudiantes Asiático‐Americanos e Isleños del Pacífico. Los análisis de covarianza indicaron que, comparado con el grupo de comparación, el grupo de tratamiento expresó unos niveles significativamente mayores de apoyo social, participación escolar, interés en el aprendizaje, expectativas vocacionales e identidad étnica. Se discuten las implicaciones para la consejería multicultural en escuelas. 相似文献

The current study examined the associations among dimensions of perfectionism, coping, social support, and depression in 58 adolescents with a history of maltreatment. Participants completed the Child-Adolescent Perfectionism, multidimensional measures of coping and social support, and the CES-D Depression Scale. Correlational analyses showed that depression was associated with socially prescribed perfectionism, internalized emotion-oriented coping, avoidant-oriented distancing, and low family support and peer support. Analyses of coping responses and perfectionism established links between self-oriented perfectionism and internalized emotion-oriented coping responses and self-reliant problem-solving. Socially prescribed perfectionism was associated with avoidance-oriented coping (i.e., distancing). While self-oriented perfectionism and social support were unrelated, socially prescribed perfectionism was associated with reduced levels of family support. Collectively, the findings highlight the roles of poor coping and social support as contributors to the emotional distress experienced by maltreated adolescents. Moreover, it is suggested that the distress experienced by perfectionistic youth with a history of maltreatment reflects, in part, the role of maladaptive coping styles and coping resource deficits. Our findings support further consideration of personality dimensions such as perfectionism as contributors to poor functioning among maltreated youth. 相似文献

The current study examined the extent to which an expanded self-punitiveness model could be applied to deliberate self-harm
(DSH) among students making the transition to university. Specific components of the self-punitiveness model included perfectionism,
overgeneralization, self-criticism, and shame. A sample of 319 university students completed a measure of deliberate self-harm
as well as two multidimensional perfectionism measures and measures of self-criticism, overgeneralization, and shame. Correlational
analyses found few significant associations among deliberate self-harm and the self-punitiveness factors among men. In contrast,
among women, deliberate self-harm was associated with dimensions of trait perfectionism such as parental criticism and socially
prescribed perfectionism, as well as with overgeneralization, self-criticism, and both characterological shame and bodily
shame with the strongest associations found with shame. Supplementary analyses found a strong link between overgeneralization
and shame and an association between self-criticism and shame among women. The results support the contention that particularly
among young women making the transition to university, deliberate self-harm behavior is a reflection of a self-punitive personality
orientation with multiple facets and a sense of shame associated with an overgeneralized sense of failing to meet social expectations. 相似文献

Undergraduate counselors‐in‐training completed the Substance Abuse Attitude Survey, which measures treatment intervention, treatment optimism, and nonstereotypical attitudes. Treatment optimism was positively correlated with nonstereotypical attitudes and treatment intervention. Results indicated that treatment intervention and nonstereotypical attitudes must be addressed in addiction counseling courses. 相似文献

Complex acoustic signals in many animal species are characterized by a syntax that governs how different notes are combined, but the importance of syntax to the communicative function of signals is not well understood. Mated pairs of yellow-naped amazons, Amazona auropalliata, produce coordinated vocal duets that are used for territory maintenance and defense. These duets follow rules that specify the ordering of notes within duets, such as a strict alternation of sex-specific notes and a defined progression of note types through each duet. These syntactical rules may function to define sex-specific roles, improve coordination, and allow individuals to combine calls into meaningful sequences. As a first step toward understanding the functional significance of syntax, we conducted two separate audio playback experiments in which we presented nesting pairs with normal duets and duets with broken syntax (i.e., one of the syntactic rules was broken). In Experiment One, we reversed the order of female and male notes within note pairs while retaining the typical progression of note types through a duet. In Experiment Two we reversed the order of note types across a whole duet while retaining the typical female-male ordering within note pairs. We hypothesized that duets with broken syntax would be less-effective signals than duets with normal syntax and predicted that pairs would respond less to broken syntax than to normal duets. Contrary to predictions, we did not observe differences in response between treatments for any variables except latency to approach the speaker. After we combined data across experiments post hoc, we observed longer latencies to approach the speakers after playbacks of broken syntax duets, suggesting that pairs could differentiate between playbacks. These responses suggest that breaking one rule of duet syntax at a time does not result in detectable loss of signal efficacy in the context of territorial intrusions. 相似文献
