Notes: This table shows the treatment effect of the PATHS intervention on cognitive and socio-emotional outcomes. University enrolment or graduation refers to age 24 and is an indicator variable. Standardized grade corresponds to the teacher-given, primary school grades obtained before taking the academic high school admission test. Estimates for admission test scores are based on the score obtained from the first time taking the test. Admission to academic high school is possible after Grades 6, 8, and 9. The second and third regression are based on inverse probability weighting, with weights constructed by regressing an indicator for whether we observe any grade or test score on the full set of controls and then taking the square of the inverse predictions. Columns (4)–(9) show the treatment effect for socio-emotional outcomes and columns (10)–(13) for classroom behaviour. The outcomes in columns (4)–(12) are averaged over survey waves and then standardized across the sample. We include Bonferroni and Bonferroni–Holm p-values to perform multiple hypotheses testing. All models are estimated using controls for baseline child and household characteristics. Child controls include the age and gender of the child, having Swiss citizenship, measures for anxiety and depressivity, ADHD, non-aggressive externalizing problem behaviour, non-aggressive conduct disorder, opposition and defiance, prosociality, four measures of aggressive behaviour, and four measures of overall behaviour. Household controls include household income, mother's and father's education level, age of the mother, indicator variables for the mother's having Swiss citizenship and being born in Switzerland, and indicator variables for a single-parent household, a household that received financial aid, and a household that experienced financial problems. All models include strata fixed effects for the level of randomization. Robust standard errors clustered at the school level are in parentheses. ***p < 0.01, **p < 0.05, *p < 0.1.
