Association of maternal prenatal urinary fluoride levels with ADHD symptoms in childhood.

Background: Health concerns about the potential impact of exposure to fluoride via drinking water (DW) on neuropsychological development include behavioral outcomes such as ADHD.

Objective: We aimed to examine the association between prenatal maternal urinary fluoride and symptoms associated with attention-deficit/hyperactivity disorder (ADHD) at the age of 8 and 11 years.

Method: Data from 255 to 236 mother-child pairs from the "Infancia y Medio Ambiente" (INMA) birth cohort (Gipuzkoa; Spain) with maternal urinary F adjusted for creatinine (MUFcr) during pregnancy (first and third trimester) and child assessments of ADHD-like symptoms reported by Conners' Rating Scales-Revised at age of 8 and 11 years was available.

Do prepubertal hormones, 2D:4D index and psychosocial context jointly explain 11-year-old preadolescents' involvement in bullying?

Background: Bullying is a type of aggressive behavior that occurs repeatedly and intentionally in school environments and where there is a power imbalance. The main objective of this study was to analyze the association that hormones and the psychosocial context jointly have with bullying behavior.

Method: Participants were 302 11-year-old preadolescents from the Gipuzkoan cohort of the INMA Project.

Cognitive predictors of language abilities in primary school children: A cascaded developmental view.

This study investigated the longitudinal relationship between children's domain-general cognitive constraints underlying phonological and sentence processing development in a big sample of typically developing children. 104 children were tested on non-linguistic processing speed, phonological skills (phonological short term memory, phonological knowledge, phonological working memory), and sentence processing abilities (sentence repetition and receptive grammar) in 1 grade (aged 6 to 6.5) and one year later.

Family Context Assessment in Middle Childhood: A Tool Supporting Social, Educational, and Public Health Interventions.

Quality of the family context has an important role in the physical and mental health of children; that is why it is important to have reliable and updated tools. This study aims to design and validate a new tool, the Haezi Etxadi Family Assessment Scale 7-11 (HEFAS 7-11), to assess family context quality in middle childhood. A sample of two cohorts of 772 Spanish families with children aged between 7 and 11 (M = 9.

Emotional autonomy and adjustment among emerging adults: The moderating role of family relationships.

Emerging adults build their personal maturity within the family context; however, few studies focus on the role of emotional autonomy during this stage. The aim of this study was to analyze the relationship between emotional autonomy and adjustment during emerging adulthood, bearing in mind the possible moderating role of parental support in this relationship. Data were collected from 1,502 Spanish undergraduate students (903 women) aged between 18 and 29.

Preliminary validation of the Perceived Locus of Causality scale for academic motivation in the context of university studies (PLOC-U).

Background: Research has shown that self-determination theory can be useful in the study of motivation in sport and other forms of physical activity. The Perceived Locus of Causality (PLOC) scale was originally designed to study both.

Aim: The current research presents and validates the new PLOC-U scale to measure academic motivation in the university context.
