The developed response surfaces have R 2 values (Table 5) that might be considered low for physical sciences, but indicate a moderate-large effect size according to Cohen's conventions, often cited in the psychology literature [29].
For example, a moderate-large effect size (.73) between manual acupuncture versus waiting list in reducing depression was reported in a recent Cochrane review [ 37].
Belief that health practices had a moderate-large effect on health was a significant predictor of both VM and NVNM use, even after controlling for its strong association with educational attainment.
There were large-extremely large effects on running economy (VO2) at each speed and between all BWS for men (p ≤ 0.001) and moderate-large effects for women (p < 0.001).
Moderate and moderate-large effect-size correlations were identified between contact statistics from performance analysis and changes in CK at 16 and 40 h post-match in forwards and backs, respectively (e.g. backs; total impacts vs. ΔCK (r = 0.638, p < 0.01) and Δ% CK (r = 0.454, p < 0.05) 40 h post-match).
Although the study was not designed to detect changes in anger and interpersonal violence, IPT had moderate-large effects on anger and violent victimization by an intimate partner (Table 3).
The size of DIF effects is typically categorized into three different categories (Zieky 1993, 2003): Negligible effect: <.43 Logits Light to moderate effect: ≥.43 and <.63 Logits Moderate to large effect: ≥.63 Logits.
Furthermore, a recent meta-analysis conducted on social cognitive training interventions in schizophrenia [ 68] found moderate to large effect sizes on facial affect recognition (Cohen's d between 0.71-1.01) and small to moderate effect sizes on ToM (0.46).
Moderate to large effect: ≥.63 Logits.
Effect sizes of 0.01, 0.06, and 0.14 denoted small, moderate, and large effect sizes, respectively [24].
Conventionally, correlations around 0.10, 0.30 and 0.50 are considered weak, moderate and large effect sizes, respectively (Cohen 1988).
