Subclaims¶

q3 i? Across 42 reliability estimates, pooled internal consistency was α/ω = 0.89, 95% CI [0.86, 0.90], 95% PI [0.62, 0.97], with τ² = 0.36 and I² = 99.9%. → Könül Karimova 2026

q3 · i? · quant-synthesis · r2

Random-effects meta-analysis of internal consistency coefficients (log-transformed, REML) from 42 estimates in the systematic review. The pooled estimate was "high" with a wide prediction interval, and heterogeneity was very high (τ² = 0.36, I² = 99.9%).

"the pooled internal consistency estimate across 42 reliability estimates was high, α/ ω= 0.89, 95% CI [0.86, 0.90], with a 95% prediction interval of [0.62, 0.97]"

Discussion¶

Related Claims¶

• Reliability estimates vary by region and instrument, with ARS showing α/ω = 0.90 and ABS α/ω = 0.82, and the evidence base geographically uneven — a narrower finding that bears on this claim
• Meta-analytic average Cronbach's Alpha of domain-specific knowledge tests is 0.85 with expected item intercorrelation of 0.22 — related
• Pooled construct validity correlation between academic resilience measures and external criteria is moderate (r = .55) with substantial variability across outcome domains — related
• Effect sizes for gender differences in L2 achievement are highly heterogeneous across studies (I² = 89.82%) — related
