Relationship Between Change in Participation and Later Mental Health Problems in Children.

Background: Participation in everyday activities is beneficial for mental health. However, little is known about the extent to which changes in children's participation are associated with later mental health.

Objectives: To investigate the association between changes in the frequency and involvement in home, school, and community activities and subsequent mental health problems in children.

Validation of a developmental screening checklist for Chinese preschoolers in Hong Kong.

There are concerns about the cultural validity of applying developmental screeners developed and normed in Western countries to other sociocultural contexts. Given the scarcity of culturally validated developmental checklists for use among Chinese children, the Hong Kong Society for the Protection of Children (HKSPC) has developed the HKSPC Developmental Checklist (HKSPC-DC) for preschool teachers to identify children at risk of developmental delays through daily observation of children's functioning at school. This study explored the psychometric properties of the HKSPC-DC among 1183 preschool children aged 2-6 recruited from 14 nursery schools in Hong Kong.
