Latent MTMM analysis with time (2018 vs 2019) as method facet, based on the 12-factor ESEM solution from 1,950 Australian school leaders. The article reports "mean r = .704, SE = .017" for convergent validity, with APC tests supporting the MTMM inequalities.

"Convergent validity (same construct across time): mean r = .704, SE = .017, indicating substantial stability and coherence for each need facet across waves."

Discussion¶

Related Claims¶

• The BPNSFS 3×2 six-facet structure (three needs × satisfaction/frustration) fits Australian school-leader data excellently and better than models collapsing valence — related
• Three-facet MTMM (content × valence × time) supports the SDT 3×2 architecture, with content the stronger separative force and 20 of 21 planned comparisons supported — related
• Bivariate SDT-based predictions about BPNSFS correlates were largely upheld: valence predictions correct for 95.2% and content predictions for 91.4% of scored cases — related
