	Eco-social conservation intentions						0.126
	Eco-social purchase intentions						−0.521

Note: ESCCBCONINT1, ESCCBCONINT2, and ESCCBCONINT3: Eco-social conservation intention indicators; ESCCBUSEINT1, ESCCBUSEINT2, and ESCCBUSEINT3: eco-social use intention indicators; ESCCBPURINT1, ESCCBPURINT2, and ESCCBPURINT3: eco-social purchase intention indicators; RMSE = root mean square error; LM = linear regression model; MAE = mean absolute error; predictive validity exists when the PLS-LM columns are negative for errors (RMSE and MAE) and positive for Q².
