module devised by researchers, comprised of four sessions given at three weeks interval to intervention school.
Chi-square test, Independent sample-t-test and ANOVA were applied for analysis.
Results: Critical-thinking skills {Wilks’s Lambda=0.061,F(2,208)=1602.82,p<0.001, η2=0.94} and decision-making
skills {Wilk’s Lambda=0.11,F(2,208)=831.84,p<0.001, η2=0.89} of the experimental group improved significantly
across the three time points but not for the control group. Between the group comparison indicated that mean
change in scores for both the skills was significantly greater for experimental group (p<0.001) when compared to
control. Life skills intervention module had a large effect size for both the skills at both the post-tests
