Children's motor proficiency is negatively associated with body fat, and normal weight children show better motor competence than those who are overweight or obese. The negative impact of excessive body weight is stronger for gross motor skills that involve dynamic body movements than for stationary object control skills; fine motor skills appear to be relatively independent of the constraints imposed by excessive body weight.

of outdoor physical play for preschoolers' social success. Moreover, the study suggests that the environment in which children play has an important effect on the adaptive nature of their play.

Emotional functioning plays a crucial role in the social development of children and adolescents. We examined the extent to which emotion control was related to the quality of friendships in pre-adolescents with and without hearing loss. We tested 350 pre-adolescents (75 deaf/hard of hearing in mainstream education (DHHm), 48 deaf/hard of hearing in special education (DHHs), and 227 hearing) through self-report. Outcomes confirmed a positive association between emotion control and positive friendships for all groups, with one notable exception: more approach strategies for emotion regulation were associated with more negative friendship features in the DHHs group. In addition, the DHHm group demonstrated high levels of emotion control, while their levels of positive friendship features were still lower compared to the hearing group.

Interoceptive awareness involves several mind-body dimensions and can be evaluated by self-report with the Multidimensional Assessment of Interoceptive Awareness (MAIA), which has been translated and validated in several countries and is being used in research and clinical contexts. This study systematically translated the MAIA with six additional items using a focus group and evaluated its psychometric properties in a respondent sample of 204 Portuguese university students (52% females; M ¼ 21.3, SD ¼ 3.9 years). Based on exploratory factor analysis, we refined the tool into a 33-item version and tested it in a separate sample (n ¼ 286; 63% females; M ¼ 21.3, SD ¼ 4.7 years). We then conducted confirmatory factor analysis and examined test-retest reliability and convergent and discriminant validity. We confirmed an acceptable model fit for this Portuguese version (MAIA-P) with 33 items and seven scales; it showed good construct validity and acceptable temporal
