Meta-analytic age group mean-score differences (δ) for influencing others behaviors.

Age group	k	Nyounger	Nolder	d	SDd	SEd	SDres	δ	SDδ	90% CI	Credibility interval
18–35	22	1871		0.00				0.00
36–45	22	1871	1363	0.03	0.19	0.01	0.06	0.04	0.08	0.03, 0.05	−0.06, 0.14
46–55	21	1744	894	0.20	0.26	0.04	0.14	0.27	0.19	0.18, 0.37	0.03, 0.51

All age groups are compared to the 18–35 years old baseline. k, number of samples included in the meta-analysis; N, total sample size for the respective age group across samples; $\overline{d}$, sample size weighted mean observed group difference; SD_d, standard deviation of d; ${SE}_{\overline{d}}$, sampling error of $\overline{d}$; SD_res, residual standard deviation; δ, sample size weighted mean group difference, corrected for attenuation due to measurement error in the Employee Green Behavior scales; SD_δ, standard deviation of δ; CI, 90% two-tailed confidence interval; credibility interval, 80% credibility interval. The mean square root of internal consistency reliability estimate ($\sqrt{\alpha }$) across samples was 0.74.
