To test the strength of the relationship, Cohen’s the mean difference divided by the standard deviation. For the sample items, how often do you feel completely alone? How often do you feel shut out and excluded by other? For this the Cronbach’s was a=.90, m=2.16, and the SD=.63. Also, in the same study the participants filled out 4 items subjective happiness scale with the Cronbach’s a =.87, m=5.31, SD=1.10, and for depression scale with the Cronbach’s a=.75, m=1.83, and SD=.49. the major effect statistically significant because the results shows that the intervention did not affect the participant’s subjective happiness
