Prevalence studies of problematic behaviors in four-year-olds.
Prevalence rates for specific behaviors in the Problem Behavior Questionnaire (PBQ; Behar & Stringfield, 1974) and for four psychosomatically related behaviors (soiling, day and night wetting, and complaints about bodily aches) were estimated in a sample of 377 Swedish 4-year-olds described by their parents (mainly mothers). The results showed that several of the behaviors classified as outgoing conduct problems were common in this age group; boys showed more problematic behaviors than girls, as did children with older siblings. Firstborn children with younger siblings were more fearful and worried. No systematic differences between children in different types of day care were found. Maternal education had no relationship to reported child behaviors. The findings were discussed in terms of the four-year-age period as a period of transition and with regard to different family situations.
