title: An effective psychoeducational intervention for early childhood caries prevention: part I.
abstract: OBJECTIVE
  The purpose was to compare whether mothers exposed to an autonomy-supportive psychoeducational videotaped message, informed by the self-determination theory (SDT), demonstrated greater changes in oral health knowledge and behavioral intentions as a preventive means for early childhood caries (ECC) than mothers exposed to a neutral message delivered by brochure.
  
  
  METHODS
  Data were collected at baseline, one-, and six-month follow-ups from 415 12- to 49-month-old WIC-enrolled children and their mothers: 283 in the video intervention group and 132 in the brochure control group. Mothers completed questionnaires on maternal knowledge and behavioral intentions for oral health care. Chi-square, Wilcoxon rank-sum, and Mann-Whitney tests were used to analyze data (P<.05).
  
  
  RESULTS
  Relative to their baseline scores, the intervention group showed a greater increase in knowledge than the control group, both at one-month (P=.002) and six-month follow-ups (P<.001). The video group also demonstrated a greater increase in behavioral intentions than controls, both at one-month (P<.05) and six-month follow-ups (P<.001). Knowledge and behavioral intention levels at six-month follow-up did not differ significantly from those at one-month follow-up, indicating that intervention-based increases in these measures were maintained over time.
  
  
  CONCLUSIONS
  Data provided evidence of the effectiveness of the autonomy-supportive psychoeducational intervention for ECC prevention relative to a neutral brochure.
