Subclaims¶

q2 i? The intervention was associated with students' self-esteem across pre-, post- and retention tests (Friedman test significant). → Heyne Thomas & Bogner Franz X 2013 q2 i? Control group self-esteem scores did not differ over the study period; equivalence was not tested. → Heyne Thomas & Bogner Franz X 2013 (2)

Evidence¶

Heyne Thomas & Bogner Franz X 2013¶

Heyne Thomas & Bogner Franz X. (2013). Drug Prevention by Increasing Self-Esteem: Influence of Teaching Approaches and Gender on Different Consumption Groups. World Journal of Education, 3(1). https://doi.org/10.5430/wje.v3n1p1

q2 · i? · causal · r1

Quasi-experimental intervention study of 282 low-achieving eighth graders with self-esteem measured at pre-test, post-test and retention. The article reports "Chi-Square = 46.55; df = 2; p < .001" for the total group, with only small effect-size changes between T1 and T3 and T2 and T3.

"Our educational intervention was associated with students’ self-esteem over all test dates (Friedman Test, Chi-Square = 46.55; df = 2; p < .001)."

Heyne Thomas & Bogner Franz X 2013 (2)¶

q2 · i? · causal · r1

A control group (n = 46) served for test assessment and exclusion of external influences; it was measured only at the end of the study (T3). The article reports "Z = -1.568; p = .117", i.e. no detected change.

"Control group scores did not differ at all (Wilcoxon, Z = -1.568; p = .117)."

Discussion¶

Related Claims¶

• The currently curious cluster (CC) showed no self-esteem response to the life skills program — related
• Successful program completion increased participants' self-confidence, self-esteem, and autonomy, which aided their settlement and integration into Canadian society — related
• Only the potentially curious cluster (PC) changed its self-esteem in a pedagogically significant manner in response to the program — a narrower finding that bears on this claim
• PC-cluster self-esteem increased irrespective of the preceding teaching method, though a late change appeared under the teacher-centered method — a narrower finding that bears on this claim
