This study characterized women's concurrent and subsequent levels of emotional distress associated with a questionable mammogram screening and relationships between women's coping and psychosocial adjustment. State anxiety was assessed in 98 women 1 day after receiving a mammogram screening (Time 1), after notification of a questionable screening result that necessitated additional testing (Time 2), and after being informed of their breast-cancer-free status (Time 3). Key findings include (a) women reported a significant increase in anxiety following notification of the need to return for follow-up testing; (b) significant and positive associations were found between anxiety and behavioral approach, behavioral avoidance, cognitive approach, and cognitive avoidance coping in cross-sectional analyses; and (c) cognitive avoidance coping was a strong predictor of final levels of state anxiety in women. Findings suggest that cognitive avoidance coping plays an important role in reducing anxiety in women recalled to clarify an initially ambiguous screening procedure.  相似文献

An embedded mixed-methods design was implemented with 34 elementary-age students (mean age = 10.15 years, SD = 0.65) to evaluate salient experiences and improvements in protective factors and life satisfaction associated with a subjective well-being intervention program (SWIP). Analyses resulted in a model of participant experiences in which thematic experiences with SWIP participation (improved emotional expression, enhanced self-discovery, and increased empathy) promoted the emergence of protective factors (self-concept and self-confidence) that contributed to life satisfaction.  相似文献

We compared long-term growth patterns in teachers’ and mothers’ ratings of Overt Aggression, Covert Aggression, Oppositional Defiance, Impulsivity/inattention, and Emotion Dysregulation across developmental periods spanning kindergarten through grade 8 (ages 5 to 13 years). We also determined whether salient background characteristics and measures of child temperament and parenting risk differentially predicted growth in discrete categories of child externalizing symptoms across development. Participants were 549 kindergarten-age children (51% male; 83% European American; 17% African American) whose problem behaviors were rated by teachers and parents each successive year of development through 8th grade. Latent growth curve analyses were performed for each component scale, contrasting with an overall index of externalizing, in a piecewise fashion encompassing two periods of development: K-1and grades 1–8. Our findings showed that there were meaningful differences and similarities between informants in their levels of concern about specific forms of externalizing problems, patterns of change in problem behavior reports across development, and in the extent to which their ratings of specific problems were associated with distal and proximal covariates. Thus, these data provided novel information about issues that have received scant empirical attention and have important implications for understanding the development and prevention of children’s long-term externalizing problems.  相似文献

Religion and spirituality are known influences on medical providers’ care of patients, but no studies have assessed resident beliefs related to patient perception of clinical care. The main objective of our study was to assess resident religious affiliation, religiosity, and spirituality in relation to self-efficacy and communication with patients during adolescent clinic visits. We found that religious affiliation and religiosity appear to affect patient perception of communication with residents during adolescent visits; spirituality had little noted effect. Further research is warranted, especially regarding resident and patient gender correlations and differences in religious affiliation effects on patient perception of care.  相似文献

We summarize the results of four recent translational studies from our lab that used the predictions of behavioral momentum theory to inform the development of more durable treatments for destructive behavior. Treatments informed by behavioral momentum theory generally showed better suppression of target responding during an extinction challenge than did a comparison treatment. We reanalyze data from each of the four studies to show that this general finding is apparent both at the aggregate (i.e., proportion of baseline response rates averaged across participants) and within participant (i.e., percentage reduction in proportion of baseline response rates, difference in raw response rates during the extinction challenge). Interestingly, participants who experienced multiple cycles of the extinction challenge generally showed less differentiation in target responding between the treatment informed by behavioral momentum theory and the comparison treatment. Overall results suggest that applications of behavioral momentum theory can substantially improve the durability of common treatments for destructive behavior.  相似文献
