The Internalized Stigma of Mental Illnesses Scale (ISMI) was developed by Boyd-Ritsher et al. (2003), and adapted into Turkish by Ersoy and Varan (2007). Then, by Dikeç et al. (2019) based on ISMI, the scale items were adapted to the parents of individuals with mental illness, and Turkish validity reliability was established. The scale consists of 29 items. The scale includes "alienation (item: 1,5,8,16,17,21)", "confirmation of stereotypes (item: 26,10,18,19,23,29)", "perceived discrimination (item: 3.15)". ,22,25,28)", "social withdrawal (item: 4,9,11,12,13,20)", "resistance to stigma (item: 7,14,24,26,27)" It has five subscales. The items in the scale are answered as "strongly disagree" (1 point), "disagree" (2 points), "agree" (3 points), "strongly agree" (4 points). The scale total score ranges from 29 to 116 and there is no scale cutoff score. A high score from the scale indicates that the internalized stigma of the person is more severe in the negative direction.

The scale was developed by Diener et al. (2009-2010) and adapted into Turkish by Telef (2013). The scale, which consists of eight items in total, has a seven-point Likert structure (1=Strongly disagree, 2=Disagree, 3=Somewhat disagree, 4=Undecided, 5=Disagree a little, 6=Agree, 7=Strongly agree). All items in the scale are expressed positively and the scale has no sub-dimensions. The lowest score obtained from the scale is 8, and the highest score is 56. The total score obtained from the scale is determined by adding the values given to all the items in the scale. A high score from the scale indicates that the person has a high level of psychological well-being.
