PLOC-U is a good instrument for the measurement of academic motivation and provides a new tool to analyse self-determination among university students.

This paper presents an essay that uses an epigenetic approach to attain an inclusive and in-depth understanding of the influence of family context and quality of parenting on children’s psychological development. Based on the identification of a key developmental process in which interactions are continuously internalised, the approach draws attention to the bidirectional and systemic nature of intrafamily and parenting interactions and highlights the multiple factors that influence them, which are linked to the developmental history of the species, the individual characteristics of both the child and their parents, and contextual variables. In response to these internalised interactions, the body activates epigenetic mechanisms, such as DNA methylation, which may affect the phenotypic expression of the genome. Theoretical and methodological implications are discussed in light of the current process of identifying the biological profiles underlying negative and positive parenting practices. Some insights are offered regarding the challenges and opportunities that parents and policymakers should address in the 21st century in connection with the promotion of positive parenting, taking into account the epigenetic processes triggered by adverse environments for children and their families.

Recent research suggests that Attention Deficit Hyperactivity Disorder (ADHD) may be influenced by interactions between the individual and their social context. This study examined the predictive value of family context variables and attentional control levels on child ADHD symptoms. A new explanatory model of the relationship amongst these variables was also tested. A sample of 754 families with children aged 7 to 11 was assessed through the Conners Parent Rating Scale, the Haezi-Etxadi Family Assessment Scale, and the Attention Network Test. Path analysis models showed a predictive association between children ADHD symptoms and Social Support Network, Parental Stress, Parental Self-efficacy, Attentional Control and being male. Furthermore, a stronger Social Support Network was associated with greater Parental Self-efficacy, a variable that predicted Parental Stress levels and children ADHD symptoms. In conclusion, a new multi-influence model of variables linked to ADHD symptomatology during mid-childhood is provided, which may be useful to support the design of family interventions.
