Post-divorce representations of marital negotiation during marriage predict parenting alliance in newly divorced parents

Literature demonstrates that marital and co-parenting subsystems are intercorrelated and have autonomous functions in the family system. This study explored representations of marital negotiation strategies for conflict resolution during marriage and parenting alliance relationship after divorce, using data from Portuguese newly divorced parents. In multiple regression analysis, representations of marital negotiation strategies for conflict resolution during marriage used by ex-spouses predict positive parenting alliance relationship after divorce. These results suggest that representations of pre-divorce marital relationship influence positively current interparental relationship regarding child rearing after marital dissolution. Implications for clinical interventions are also discussed.

Attachment to parents: the mediating role of inhibition of exploration and individuality on health behaviors

This study’s goal was to analyze whether the quality of university students’ relationship with their parents mediated the association between mental health and physical symptoms and health behavior. Participants were 250 university students (66% female and 34% male), aged between 17 and 29 years old (M = 20.88, SD = 2.03) that answered the Father/Mother Attachment Questionnaire (FMAQ), the Physical Symptoms Scale from the Rotterdam Symptom Checklist (RSCL), the Health Behavior Questionnaire (HBQ), and the Hospital Anxiety and Depression Scale (HADS). The results showed that the indirect effect of physical symptoms on health behavior was significantly mediated by the father’s and mother’s inhibition of exploration and individuality (IEI). Also the indirect effect of psychological distress on health behavior was significantly mediated by the father’s and mother’s IEI. These results suggest that young adults who had more restrictions to their individuality show worse health behaviors. Separation Anxiety and Dependence (SAD) and Quality of Emotional Bond (QEB), the other 2 attachment scales, were not mediators of the relationship between physical symptoms/ psychological distress and health behavior. This study shows the importance of promoting positive parenting practices that contribute to healthier behavior choices and less risky behaviors, as well as the need for more studies that clearly identify these practices in young adult populations.

Attachment style impacts behavior and early oculomotor response to positive, but not negative, pictures

The present study investigated whether oculomotor behavior is influenced by attachment styles. The Relationship Scales Questionnaire was used to assess attachment styles of forty-eight voluntary university students and to classify them into attachment groups (secure, preoccupied, fearful, and dismissing). Eye-tracking was recorded while participants engaged in a 3-seconds free visual exploration of stimuli presenting either a positive or a negative picture together with a neutral picture, all depicting social interactions. The task consisted in identifying whether the two pictures depicted the same emotion. Results showed that the processing of negative pictures was impermeable to attachment style, while the processing of positive pictures was significantly influenced by individual differences in insecure attachment. The groups highly avoidant regarding to attachment (dismissing and fearful) showed reduced accuracy, suggesting a higher threshold for recognizing positive emotions compared to the secure group. The groups with higher attachment anxiety (preoccupied and fearful) showed differences in automatic capture of attention, in particular an increased delay preceding the first fixation to a picture of positive emotional valence. Despite lenient statistical thresholds induced by the limited sample size of some groups (p < 0.05 uncorrected for multiple comparisons), the current findings suggest that the processing of positive emotions is affected by attachment styles. These results are discussed within a broader evolutionary framework.

Family relationship and parenting practices: a pathway to adolesents’ collectivist and individualist values?

Adolescents’ perceptions of parenting and family relationships are important variables for identifying mechanisms involved in how children acquire values and how these values are transmitted through families. In a sample of 515 adolescents, we investigated whether perceptions of the quality of parental practices would predict adolescents’ collectivist and individualist values. We hypothesized that perceived quality of family relations would mediate the relationship between the quality of parental practices and collectivist values but not of individualist values. The results of structural equation modeling suggested that perception of the quality of parental practices predicted adolescents’ both collectivist and individualist values. The predicted mediation effect was found for collectivist values, but not for individualist values. The results point to different functions of parenting and family relations on value acquisition. Implications for practice, such as the development and implementation of interventions to improve the formation of adolescents’ values by enhancing the quality of parenting and family relationships are discussed.

TP perturbation of TN matrices and totally positive directions

Here, we define and consider (linear) TP-directions and TP-paths for a totally nonnegative matrix, in an effort to more deeply understand perturbation of a TN matrix to a TP matrix. We give circumstances in which a TP-direction exists and an example to show that they do not always exist. A strategy to give (nonlinear) TP-paths is given (and applied to this example). A long term goal is to understand the sparsest TP-perturbation for application to completion problems.

Clinical characteristics of women diagnosed with carcinoma who tested positive for cervical and anal high-risk human papillomavirus DNA and E6 RNA

High-risk human papillomavirus (hrHPV) is an essential cause of cervical carcinoma and is also strongly related to anal cancer development. The hrHPV E6 oncoprotein plays a major role in carcinogenesis. We aimed to evaluate the frequency of hrHPV DNA and E6 oncoprotein in the anuses of women with cervical carcinoma. We analyzed 117 women with cervical cancer and 103 controls for hrHPV and the E6 oncogene. Positive test results for a cervical carcinoma included 66.7 % with hrHPV-16 and 7.7 % with hrHPV-18. One case tested positive for both HPV variants (0.9 %). The samples from the anal canal were positive for HPV-16 in 59.8 % of the cases. Simultaneous presence of HPV in the cervix and anal canal was found in 53.8 % of the cases. Regarding expression of E6 RNA, positivity for HPV-16 in the anal canal was found in 21.2 % of the cases, positivity for HPV-16 in the cervix was found in 75.0 %, and positivity for HPV-18 in the cervix was found in 1.9 %. E6 expression in both the cervix and anal canal was found in 19.2 % of the cases. In the controls, 1 % tested positive for HPV-16 and 0 % for HPV-18. Anal samples from the controls showed a hrHPV frequency of 4.9 % (only HPV16). The presence of hrHPV in the anal canal of women with cervical cancer was detected at a high frequency. We also detected E6 RNA expression in the anal canal of women with cervical cancer, suggesting that these women are at risk for anal hrHPV infection.

The positive effect on ketamine as a priming adjuvant in antidepressant treatment.

Ketamine is an anesthetic with antidepressant properties. The rapid and lasting effect of ketamine observed in preclinical and clinical research makes it a promising therapeutic to improve current major depression (MD) treatment. Our work intended to evaluate whether the combined use of classic antidepressants (imipramine or fluoxetine) and ketamine would improve the antidepressant response. Using an animal model of depressive-like behavior, we show that the addition of ketamine to antidepressants anticipates the behavioral response and accelerates the neuroplastic events when compared with the use of antidepressants alone. In conclusion, our results suggest the need for a reappraisal of the current pharmacological treatment of MD.

Ajustamento da criança à separação ou divórcio dos pais

Objetivo: O presente artigo procura relacionar e analisar evidências empíricas e teóricas sobre o impacto e os fatores associados ao impacto da separação ou divórcio dos pais no ajustamento da criança. Método: Realizou-se uma revisão agregativa da literatura, recorrendo às palavras-chave “divorce adjustment”, “child divorce” e “divorce impact”, nas bases de dados JSTOR, PsycInfo, SciELO e Medline e em livros da especialidade. Resultados: Respostas adaptativas e desadaptativas da criança são descritas, assim como potenciais resultados positivos. São principalmente discutidos os fatores mediadores e moderadores frequentemente referenciados na literatura no impacto da separação ou divórcio dos pais no ajustamento da criança. Entre esses estão: características da criança, problemas financeiros, sintomatologia psicopatológica dos pais, qualidade das práticas parentais e conflito interparental. Conclusão: Com base nas evidências empíricas e perspectivando o divórcio como uma transição desenvolvimental, levantamos a hipótese de que os problemas de ajustamento apresentados pelas crianças com pais divorciados possam ser mais bem explicados por outros fatores do que pelo divórcio/separação per se. Finalmente assumimos uma inovação conceptual de que essa transição familiar pode significar uma oportunidade de crescimento e de promoção desenvolvimental.
