Subclaims¶

q2 i? Two independent clustering procedures (Ward's method followed by K-means) yielded a four-group classification with high agreement (Ckorr = .93). → Heyne Thomas & Bogner Franz X 2013 q2 i? The potentially curious cluster (PC, n = 183) comprised 77.5% of the sample and had never tried drugs; the currently curious (CC, n = 34), experimenters (EP, n = 15) and consumers (CO, n = 4) formed smaller groups. → 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

Cluster analysis of CATI questionnaire response patterns on consumption behaviour and attitude (N = 282). The article reports a cross-tabulation of the two procedures showing "a high level of agreement of the four-cluster solution (adjusted coefficient of contingency Ckorr = .93, N = 282".

"We extracted a four-group classification using the agglomerative hierarchical Ward’s method (Norusis, 1993)."

q2 · i? · causal · r1

Descriptive cluster characterization prior to the intervention: PC made up "77.5% of the total sample"; the article further reports CC at 14.4% (n = 34), EP at 6.4% (n = 15) and CO at 1.7% (n = 4).

"The potentially curious cluster (PC; n = 183) made up 77.5% of the total sample and, thus, comprised the largest fraction of the sample which had never tried any drugs"

Discussion¶

Related Claims¶

• The currently curious cluster (CC) showed no self-esteem response to the life skills program — a narrower finding that bears on this claim
• Exploratory K-means clustering identifies four heterogeneous student AI-user profiles differing in experience, competence, usefulness, trust, and control, but the solution's optimality and stability are not established — related
• Three distinct learner profiles emerge from function art activities: Repetitivists, Simplists, and Multifunctionists — related
• Students' attitudes towards error-handling cluster into three characteristic learner types — related
• K-means clustering of LMS log data identified two distinct SRL profiles (high and low) among online students — related
• Adult learners' motivation clusters into four profiles combining autonomous and controlled regulation, replicating the structure expected from SDT research with younger students — related
