The risk of telling : a dyadic perspective on romantic partners' responses to child sexual abuse disclosure and their associations with sexual and relationship satisfaction

Essai présenté à la Faculté des arts et des sciences en vue de l'obtention du grade de Doctorat en psychologie clinique (D. Psy.)Les survivants d’agression sexuelle à l’enfance (ASE) doivent souvent composer avec les conséquences à long terme de ce trauma. Toutefois, il existe une grande variabilité quant aux impacts individuels de l’ASE. Certains auteurs croient que la réponse obtenue lors du dévoilement de l’ASE aux proches du survivant, pourrait être l’un des déterminants de cette variabilité. Cependant, le dévoilement à l’âge adulte, notamment au partenaire amoureux, a été peu étudié. La présente étude examine les associations entre les réponses des partenaires amoureux au dévoilement, tels que perçues par les survivants, ainsi que la satisfaction sexuelle et conjugale des deux membres du couple, auprès d’un échantillon de 70 couples de la communauté ayant rapporté une ASE et l’ayant dévoilée à leur partenaire. Les participants ont complété des questionnaires auto-rapportés en ligne. Les résultats d’analyses de trajectoire au sein d’un modèle « Actor-Partner Interdependence Model » (APIM) indiquent que les réponses de « soutien émotionnel » de la part des partenaires durant le dévoilement, telles que perçues par les survivants, étaient positivement associées à leur propre satisfaction sexuelle ainsi qu’à celle de leur partenaire. Les réponses de « stigmatisation/se sentir traité différemment » de la part des partenaires, telles que perçues par les survivants, étaient associées à une moins bonne satisfaction conjugale, à la fois pour les survivants et leurs partenaires. Les résultats suggèrent que les réponses des partenaires au dévoilement d’une ASE, tels que perçues par les survivants, peuvent avoir un impact positif autant que négatif sur la satisfaction conjugale et sexuelle des deux partenaires.Survivors of childhood sexual abuse (CSA) often experience adverse trauma-related long term consequences, which vary widely among survivors. Some authors argued that this variability might be explained in part by the response of others to survivors’ disclosure of the CSA. However, disclosure during adulthood has received little empirical attention, in particular, disclosure to a romantic partner. Among 70 community couples who reported CSA and disclosure to their partner, this study examined associations between survivors’ perception of partner responses to their disclosure, and both partners’ sexual and relationship satisfaction. Participants completed self-report questionnaires online. Results of path analyses within an actor-partner interdependence model indicated that survivors’ perceived partner responses of emotional support to disclosure were associated with their own and their partners' higher sexual satisfaction. Survivors’ perceived responses of being stigmatized/treated differently by the partner were associated with their own and their partners’ poorer relationship satisfaction. Findings suggest that survivor-perceived partner responses to the disclosure of CSA can have both a positive and a negative impact on the sexual and relationship satisfaction of both partners

Impact of smoking status on health-related quality of life (HRQoL) in cancer survivors

IntroductionThe Health-Related Quality of Life (HRQoL) often declines among cancer survivors due to many factors. Some cancer patients who smoke before the cancer diagnosis continue this harmful habit, potentially contributing to a more significant decline in their HRQoL. Therefore, this study investigates the association between smoking status and HRQoL in cancer survivors.MethodsWe conducted a cross-sectional study utilizing self-reported cancer history from 39,578 participants of the Behavioral Risk Factor Surveillance System (BRFSS) database, leveraging 2016 and 2020 year questionaries. A multidimensional composite outcome was created to assess HRQoL, integrating four distinct dimensions - general health, mental health, physical health, and activity limitations. After accounting for the complex survey design, logistic regression models were used to analyze the association between smoking status and poor HRQoL, adjusting for demographic, socioeconomic, and health-related confounders.ResultsOur study found that, after adjusting for potential confounders, current smokers exhibited a significantly poorer HRQoL than never smokers (OR 1.65, 95%CI 1.40-1.93). Furthermore, former smokers showed a poorer HRQoL than never smokers; however, this association was not as strong as current smokers (OR 1.22, 95%CI 1.09-1.38).ConclusionOur findings highlight the adverse association of smoking with poor HRQoL in cancer survivors, underscoring the importance of healthcare professionals prioritizing smoking cessation and providing tailored interventions to support this goal

Rational dimension of a basis of a regression model for adaptive short-term forecasting the state of a discrete nonstationary dynamic system

Relevance. Today, there are many methodologies for predicting power consumption of various objects. However, there is no a general methodology that is suitable for all types of energy systems, including the sectoral characteristics of small northern settlements and other objects with the stochastic nature of electricity consumption schedules. At the same time, during the development of problem-oriented forecasting methods, it is necessary to take into account computational and statistical features of forecasted time series to the maximum and apply them adequately. The mentioned circumstance prompts the creation of criteria-indicators that allow evaluating the quality of the applied model for solving the forecasting problem, correctness of its construction and correctness of applying a priori information about the object and its physical properties.Aim. Develop and apply the criteria-indicators, which allow evaluating the quality of the forecast regression model and the influence of the dimensionality of such model base on a forecasting error. Methods. The choice of rational dimensionality of the regression model basis for the adaptive forecasting problem is based on the known and developed criteria-indicators. The main provisions of such criteria-indicators were formulated, which provide an assessment of the quality of conditioning of an equivalent square matrix, the presence of uninformative elements of the matrix, and linear dependence of the columns. Results. Based on the analysis of criteria-indicators, the authors selected a rational dimension of the regression model basis for the problem of adaptive short-term forecasting of the state of discrete non-stationary dynamic systems. Conclusions. The authors have previously selected the most promising criteria-indicators and developed a normalized difference factor of diagonal predominance. This allows us to evaluate the influence of the basis size change on the regression model quality when building an approach of adaptive short-term forecasting of electricity consumption by autonomous power systems of small northern settlements on the basis of regression analysis methods. Based on the analysis of criteria-indicators the authors obtained information about the influence of the regression model basis dimension on the forecasting problem solution error. The authors stated the further stages of research to reduce this error. The paper introduces and describes one of the ways to improve the forecasting model quality. The dependence of the forecasting error on the size of the regression model basis were revealed; the criteria-indicators considered in the article were successfully applied. It is confirmed that the pre-selected and developed criteria-indicators make it possible, at the stage of compiling an equivalent square matrix and performing preliminary actions on it, to track changes within the matrix. The changes will lead to improvement in the solution of the problem of adaptive short-term forecasting

Effects of mental fatigue on soccer-specific performance in young players

The aim of this study was to investigate the effects of mental fatigue on soccer-specific physical and technical performance in young players. Twelve under-14 (U14), twelve under-16 (U16) and twelve under-18 (U18) soccer players completed the two parts of the investigation. Part one assessed the soccer-specific physical performance using the Yo-Yo Intermittent Recovery Test, Level 1 (Yo-Yo IR1). Part two assessed the soccer-specific technical performance using the Loughborough Soccer Passing and Shooting Tests (LSPT, LSST). Each part was preceded by 30 min of Stroop task or 15 min of control task performed in a randomised and counterbalanced order. Subjective ratings of mental fatigue were higher after the Stroop task compared to the control in U14, U16 and U18 in both parts. Mental fatigue significantly reduced Yo-Yo IR1 distance, alongside an increase in heart rate and ratings of perceived exertion, and this effect was moderated by age as older players showed greater declines in performance. For LSPT, original time, penalty time and performance time were significantly higher in the mental fatigue condition than in the control condition in U18. For LSST, points per shot, shot speed and shot sequence time were not significantly different between conditions in U14, U16 or U18

Soccer-specific technical performance was negatively affected by mental fatigue condition only in U18 in the LSPT

Cs and heavy metals accumulation by crops and modifying effects of biologically active substances on the root uptake of radioactive and non-radioactive contaminants

Soil contamination with Co and Cd at concentration 20–25 times exceeding the Maximum Permisible Level for sod-podzolic light loam soil produced not only negative effects on the spring barley productivity formation, but also decreasing of 137Cs root uptake. Effects of Co on the barley development and 137Cs accumulation in plants was more pronounced than Cd influence. The 137Cs activity decrease in barley biomass and harvest amounted to 2.5 and 1.6 times on Cd and Co contaminated soil, respectively. The mechanisms regulating root uptake of K by barley plants in dependence of the kind of soil contamination were discussed. Seed incrustation with Zircon and Epin did not produce significant influence on Co and Cd phytotoxicity, however the use of this plant growth regulators resulted in different in direction and value effects on Co, Cd and 137Cs accumulation in barley plants at various stages of its development. The experimental data do not make it possible to link directly the effect of biologically active substances on 137Cs uptake with their influence on heavy metals toxicity, which was estimated on the base of morphological and physiological parameters of plants
