Subclaims¶

q2 i? Reliable pre-post ART effects occurred in the two lower age groups (6-9: F(1, 237) = 5.34, p < .025; 10-14: F(1, 237) = 2.98, p < .10, not significant), but not in the oldest group, which had few participants. → Koposov 2014 q2 i? Overall social competence levels decreased significantly with increasing age, F(2, 207) = 3.19, p < .05. → Koposov 2014 (2)

Koposov 2014¶

q2 · i? · causal · r2

Age-group contrast analyses of self-report SSRS change in the quasi-experimental ART evaluation. The 6-9 contrast was significant; the 10-14 contrast was not; the 15+ group had only 8 ART and 12 control participants. No effect sizes are printed.

"Contrast analysis of the predicted pre vs. post change in th e 6-8 years ART group was significant, F (1, 237) = 5.34, p < .025. The corresponding contrast in the 10-14 yea rs ART group was not significant, F (1, 237) = 2.98 , p < .10."

q2 · i? · causal · r2

ANOVA on self-report SSRS competence across the three age groups in the same evaluation, showing competence levels decrease with age. Only the F statistic is printed.

"An ANOVA with intervention and age levels as predictor variables indicated that overal l social competence levels decreased significantly with increasing age, F (2, 207) = 3.19, p < .05."

Discussion¶

Related Claims¶

• Parent and teacher ratings of social competence improved markedly from pre to post in both ART and control groups, with no differences between the groups — reports the opposite
• An ANCOVA controlling for age, sex and institution found no significant effect of the ART intervention on change in self-reported competence scores — reports the opposite
• Younger ART participants showed increased self-reported scores on all four SSRS subscales (cooperation, assertion, empathy, self-control) from pre to post, whereas no changes were observed in the control group — a narrower finding that bears on this claim
• The 30-hour ART programme is associated with a significant increase in children's self-reported overall social competence, with no change in the control group — related
