The  result  shows  that  the  value  of  contents  validity  by  expert  panels  has high coefficient value which is = 0.822 with minimum and maximum values of over 0.60. Family self-concept sub-scale has the lowest coefficient value which   is   0.668   while   social   self-concept   sub-scale   has   the   highest coefficient value (0.964). For the overall analysis of reliability is α = 0.757 with  the  values  of  each  sub-scale  are;  social α =  0.793,  ability α = 0.770, affective α = 0.744, family α = 0.680, physical α = 0.791 and academic α = 0.792. For  the  analysis  of  the  reliability  based  on  the  items  to  find  the highest reliability is question number 103 item sub scale family α = .902 and  the  lowest  was  question number  49  item  sub  scale  ability  of α = .762.

Hence, this study has succeeded to convert the MSCS that has high validity and reliability values and applicable for Malaysian teenagers.
