title: Gender differences in the behavioral associates of loneliness and social dissatisfaction in kindergarten.
abstract: BACKGROUND
  Much of the evidence suggesting that loneliness is a risk factor for socio-emotional adjustment difficulties comes from studies with older children and adolescents. Comparatively less is known about the mental health implications of loneliness in early childhood. The goals of the present study were to provide additional convergent validity of the Loneliness and Social Dissatisfaction Questionnaire for Young Children (Cassidy & Asher, 1992) and explore potential gender differences in relations between loneliness and behavior problems in early childhood.
  
  
  METHODS
  A multiple source assessment of 139 kindergarten-aged children (M(age) = 64.76 mos., SD = 4.48) was undertaken, including parental ratings, behavioral observations, child interviews, and teacher ratings.
  
  
  RESULTS
  Overall, loneliness was positively associated with anxiety, aggression, and peer exclusion. However, several gender differences were also observed.
  
  
  CONCLUSIONS
  Loneliness may be a marker variable for both early internalizing and externalizing problems. However, gender differences in the behavioral associates of loneliness are also evident.
