Early abuse experiences and subsequent gender differences in couple adjustment

The main purpose of the current study was to evaluate the relationship between early abusive experiences (sexual abuse, parental violence, and witnessing parental violence) and subsequent couple adjustment with a theoretical model that incorporates attachment and psychological distress as mediator variables. We specifically examined the variability in long-term psychosocial characteristics of child abuse survivors across women and men. A representative sample of French-Canadian couples composed of 632 men and women completed measures of child abuse, attachment, psychological distress, and dyadic adjustment. Structural equation analyses showed that, for both women and men, sexual abuse was related to dyadic adjustment through anxiety about abandonment and psychological distress. For men, experiencing physical or psychological violence was associated with dyadic adjustment through psychological distress. For women, there was an indirect relationship between witnessing physical violence and dyadic adjustment through abandonment anxiety. Differences between men and women in the long-term adjustment to childhood sexual abuse were small and not consistent with a gender-specific model of psychosocial repercussions.     

Physical consequences of falls in the elderly: a literature review from 1995 to 2010

In the last decade, population ageing has been registered as a global phenomenon. A relation exists between falling and ageing, since falling frequency increases significantly with age. In fact, one in three older adult falls annually. Although ageing is generically associated with decrease and degeneration of psychological and physical functions, it is still not common for the correct identification of risk factors to lead to a clinical prognosis of the elder being in risk of falling. Therefore, the goal of this review article is to identify, categorise and analyse typical ageing and fall factors mentioned in the literature as well as to quantify the number of times they were referenced. The research considered hundreds of publications, but analysis was then restricted to the 87 most pertinent articles written in English and published in journals or scientific magazines between 1995 and 2010. We concluded that falls among older adults can be characterised by the following: anatomic characteristics and physiological consequences of ageing; the pathologies that induce falls, which can be neurological, musculoskeletal, cardiovascular and other diseases; causes and risk factors of falls that can be behavioural, biological, environmental or socio-economic; type of physical consequences of falls, including fractures, bruises, injuries or other physical consequences; and strategies to prevent, mitigate or rehabilitate, which can be of a physical, environmental or behavioural nature.     

Design optimisation for pharmacokinetic modeling of a cocktail of phenotyping drugs

Our paper proposes a methodological strategy to select optimal sampling designs for phenotyping studies including a cocktail of drugs. A cocktail approach is of high interest to determine the simultaneous activity of enzymes responsible for drug metabolism and pharmacokinetics, therefore useful in anticipating drug–drug interactions and in personalized medicine. Phenotyping indexes, which are area under the concentration‐time curves, can be derived from a few samples using nonlinear mixed effect models and maximum a posteriori estimation. Because of clinical constraints in phenotyping studies, the number of samples that can be collected in individuals is limited and the sampling times must be as flexible as possible. Therefore to optimize joint design for several drugs (i.e., to determine a compromise between informative times that best characterize each drug's kinetics), we proposed to use a compound optimality criterion based on the expected population Fisher information matrix in nonlinear mixed effect models. This criterion allows weighting different models, which might be useful to take into account the importance accorded to each target in a phenotyping test. We also computed windows around the optimal times based on recursive random sampling and Monte‐Carlo simulation while maintaining a reasonable level of efficiency for parameter estimation. We illustrated this strategy for two drugs often included in phenotyping cocktails, midazolam (probe for CYP3A) and digoxin (P‐glycoprotein), based on the data of a previous study, and were able to find a sparse and flexible design. The obtained design was evaluated by clinical trial simulations and shown to be efficient for the estimation of population and individual parameters. Copyright © 2015 John Wiley & Sons, Ltd.     

One-Year Prospective Study on Passion and Gambling Problems in Poker Players

The concept of passion is relevant to understanding gambling behaviours and gambling problems. Longitudinal studies are useful to better understand the absence and development of gambling problems; however, only one study has specifically considered poker players. Using a longitudinal design, this study aims to determine the influence, 1 year later, of two forms of passion—harmonious and obsessive—on gambling problems in poker players. A total of 116 poker players was recruited from across Quebec, Canada. The outcome variable of interest was participants’ category on the Canadian Pathological Gambling Index, and the predictive variable was the Gambling Passion Scale. Multiple logistic regression analyses were conducted to identify independent risk factors of at-risk poker players 1 year later. Obsessive passion at baseline doubled the risk of gambling problems 1 year later (p < 0.01); for harmonious passion, there was no association. Number of gambling activities, drug problems, and impulsivity were also associated with at-risk gambling. This study highlights the links between obsessive passion and at-risk behaviours among poker players. It is therefore important to prevent the development of obsessive passion among poker players.     

Transition from playing with simulated gambling games to gambling with real money: a longitudinal study in adolescence

Digital technology advances have supported an expansion of gambling activities, which is notable via the advent of simulated gambling games. Simulated gambling reproduces ‘real’ gambling activities, which enables the users to gamble without investing money. According to research evidence, a certain number of adolescents are playing with these games, but until now little has been known about how they could facilitate the migration to gambling with real money. Using a longitudinal design with a one-year interval period, the goal of this study was to assess the potential transition between playing with simulated gambling and the initiation to gambling with real money. The final sample was constituted of 1220 adolescents (age range = 14 to 18 y.o.) who had never played with real money at the first measurement time. At the second measurement time, 28.8% of the participants had gambled for the first time with real money. Logistic regressions revealed that the predictive association between simulated gambling and gambling with real money only holds for adolescents who transitioned from simulated poker to poker with real money. These findings highlight the need for regulation and monitoring on Internet gambling poker sites, as well as further research to assess the mechanisms at work.     

On the trail of line managers as talent spotters

The deliberate identification of talent is a critical process in most organizations. Performance ratings and senior management recommendations are its main sources, revealing the importance of line managers in the process. Nevertheless, some managers do have a talent for talent spotting and little is known about their behaviours as effective talent spotters. We explore, through social cognition, as part of the social psychology framework, the practices required to execute the talent identification process (TIP). An exploratory and qualitative method was adopted for this study; 21 line managers of an Argentine holding describe their experiences as talent spotters through semi-structured interviews. Findings show that the identification process is a complex and iterative one, in which several behaviours come into play, interrelated among each other. This interaction involves talent identification and talent development behaviours, deployed in a synergetic way. The relationship building behaviours set the foundations for the identification process to bear fruit. Distinct skills are necessary at different stages of the identification process for line managers to fulfil the talent spotter role. Finally, a model of the TIP is proposed.
