The results calculation depend on what scales (what variables) you are interested in. First of all, if you have the inventory in paper version, the most intuitive way is to make an SPSS file with the answers as they were checked by the patients. Patients in rows, items in columns. Column1=item 1, value: 1, 2, 3, 4, 5 or 6 (the checked one) and so on. Then, you calculate respective scales score by using Transform->Compute variable and defining the sum of the items you need.

You can enter the data for all the 38 items first in the SPSS. As per the scoring key it has two global scales one is psychological distress scale and the another one is psychological well-being. The psychological distress scale consists of 24 items (2, 3, 8, 9, 11, 13, 14, 15, 16, 18, 19, 20, 21, 24, 25, 27, 28, 29, 30, 32, 33, 35, 36 and 38).
The reverse scoring (6-1) must be adopted for the items 2, 3, 11, 13, 15, 16, 19, 20, 21, 24, 25, 27, 29, 30, 32, 33, 35, 36, 38 and for item 9, and 28 recoded as 5-1
You must very careful while entering the data. The score range was 1-6 for all the 24 items except item number 9 and 28 for which the score rang is 1-5. Now you can compute all the 24 items in to different variable. Higher scores on psychological distress indicate negative states of mental health.
The psychological distress scale consists three sub scales namely : anxiety – (9 items) 3, 11, 13, 15, 25, 29, 32, 33 and 35 (higher scores = greater anxiety), depression – (4 items) 9, 19, 30 and 36,( higher scores = greater depression) and loss of behavioural / emotional control - (9 items) 8, 14, 16, 18, 20, 21, 24, 27 and 28 (higher scores = greater loss of behavioural / emotional control). The two items 2 & 38 in the psychological distress sub scales were not used to score sub scales.
To calculate the score for sub scales compute the items mention against each sub scale in to different variable.
Now you can get total score for anxiety , depression and loss of behavioural / emotional control also
The Psychological Well-being consists of 14 items (1, 4, 5, 6, 7, 10, 12, 17, 22, 23, 26, 31, 34 and 37)
Now you can compute all the 14 items in to different variable.
Now you can compute all the 14 items in to different variable. Higher scores on psychological well-being indicate positive states of mental health.
To calculate the score for sub scales psychological well being - compute the items mention against each sub scale in to different variable.
Now you can get total score for positive affect, emotional ties and life satisfaction scales.
Items 22 was not included in computing the psychological well being sub scales
In order to calculate the overall mental health score compute all the 38 items in to different variable. The items 1, 4, 5, 6, 7, 8, 10, 12, 14, 17, 18, 22, 23, 26, 31, 34, and 37 are to be re-coded as 6-1. After scoring the 38 items, item scores are summed to calculate the overall mental health score. That compute in to different variable in SPSS file
Now you can obtain overall mental health score
Higher scores reflect more frequent occurrence of favourable mental health symptoms or less frequent occurrence of negative mental health symptoms
Thus, In MHI 38 you can obtain score for two global scales - Psychological Distress and Psychological Well-being;
Three sub scales in Psychological Distress - Anxiety, Depression, Loss of Behavioural / Emotional Control,
and Three sub scales in sychological Well-being- Positive Affect, Emotional Ties and Life Satisfaction; and finally
