There is limited understanding of the dynamic between relational and sexual well-being as couples adjust to new parenthood, despite this being a vulnerable period for couples' relationships. This study was aimed at examining the bidirectional links between relationship quality and sexual well-being (i.e., sexual satisfaction, sexual distress) across the transition to parenthood. We assessed new parent couples (N = 257) across four time points (two prenatal) from mid-pregnancy through 6 months postpartum. Parallel dyadic latent growth curve modeling was employed to examine the associations between trajectories of perceived relationship quality, sexual satisfaction, and sexual distress. New parents' declines in relationship quality were associated with declines in own and partners' sexual satisfaction and with increases in own sexual distress. Mothers' prenatal relationship quality and sexual distress predicted subsequent changes in own sexual distress and fathers' relationship quality, respectively. Results indicate that changes to new parents' relational and sexual well-being mutually influence each other over time. Current results indicate that the impact of the transition on couples' relationships is partly determined by own and partners' prenatal factors, to which clinicians and researchers can attend to early on. Cross-domain links between relational and sexual well-being should be considered in research and clinical practice. 相似文献

In three experiments we investigated the role of associative learning in the acquisition of response priming by effect stimuli, by examining their interaction during response-effect learning. Having replicated the ability of visual effect stimuli to prime their associated responses, we paired a response with a compound consisting of visual and auditory effects before assessing the ability of the auditory effect stimulus to prime the response. This priming was reduced if the visual stimulus had been pre-trained as an effect of the response. By contrast, priming by the visual effect stimulus was potentiated when the auditory effect had been pre-trained. We interpret these interactions in terms of contemporary associative learning theory derived from studies of conditioning. 相似文献

There is disagreement in the suicide literature on the value of suicide notes as a data source, particularly regarding the extent to which suicide decedents who write notes differ from those who do not. Using 10 years of suicide cases from Summit County, Ohio, these two groups were compared on 40 variables including sociodemographic characteristics, reported affect before death, precipitating events, physical and mental health status and care, and method of suicide. The only differences found were that note writers were more likely to have lived alone and had made prior suicide threats. These findings suggest that for research purposes, suicide cases with and without notes are essentially similar. 相似文献

Our aim was to build a model delineating the relationship between attitudes toward suicide and suicidal behavior and to assess equivalence by applying the model on data from different countries. Representative samples from the general population were approached in Sweden, Norway, and Russia with the Attitudes Toward Suicide (ATTS) questionnaire. Data on experience of suicidal behavior among significant others and self‐reported suicidal expressions were also collected. Structural equation modeling resulted in gender and country specific models where experience of suicidal behavior among significant others and self‐reported suicidal expressions earlier in life predicted attitudes, and attitudes predicted current suicidal expressions. The models included the attitude factors acceptance of suicide, condemnation, and preventability; age and level of education were also incorporated. The different models reveal possible ways to better understand gender and culture‐specific paths between attitudes and suicidal behaviors, and their relevance in a suicide prevention context is considered. 相似文献

The results of a systematic literature review that investigated suicide intent are presented. Of the 44 relevant articles identified, 17 investigated the relationships between various suicide risk factors and suicide intent and 25 publications investigated the relationships between suicide intent and various suicide outcomes. Despite recent advancements in the definition and nomological validity of suicide intent, a high degree of variability in the empirical measurement and analysis of suicide intent was found. Such variability limits future research related to measuring suicidal risk and outcomes, reporting suicide intent, or the meaningful comparison of diagnostic approaches or treatments across multiple studies. 相似文献

The aim of this paper was to estimate how suicide rates in the United States are affected by changes in per capita consumption during the postwar period. The analysis included Annual suicide rates and per capita alcohol consumption data (total and beverage specific) for the period 1950–2002. Gender‐ and age‐specific models were estimated using the Box‐Jenkins technique for time series analysis. No significant estimate was found for males. For females the total alcohol estimate (0.059) was significant at the 10% level whereas the spirits estimate was significant with an effect of 0.152. The results imply that a change in U.S. per capita consumption would result in a change in female suicide rates, whereas the male rates would not be affected. 相似文献

There is much empirical literature on factors for adolescent suicide risk, but body image and disordered eating are rarely included in these models. In the current study, disordered eating and body image were examined as risk factors for suicide ideation since these factors are prevalent in adolescence, particularly for females. It was hypothesized that disordered eating and body image, in addition to depressive symptoms, would contribute to suicide ideation. It was also hypothesized that these relationships would be stronger for females than for males. Structural equation modeling was used to test a model of risk for suicide ideation incorporating the above factors in a sample of 392 high school students. Results indicated that disordered eating contributed to both suicide ideation and depressive symptoms, while body image only contributed to depressive symptoms. Depressive symptoms contributed to suicide ideation. The model was found to be cross‐validated with males and females, and no gender differences emerged. Implications of these findings and their importance in constructing future models of adolescent suicide risk are discussed. 相似文献
