- self-report questionnaire
- used for the detection of psychiatric distress related to general medical illness. Respondents indicate if their current “state” differs from his or her usual state - thereby assessing change in characteristics and not lifelong personality characteristics.
- designed to assess 4 aspects of distress:
3) Social impairment
Body Function – Subcategory: Mental Functions
Number of Items:
Brief Instructions for Administration & Scoring
- self-administered questionnaire
- patients base their responses on their health state over the past two weeks.
- administration time is usually approximately 5 minutes.
- Calculation of total score
- Different scoring methods of scoring are possible, which will affect the total score. The traditional scoring method provided assigns a score of 0 for responses 1 and 2 (“not at all” and “no more than usual”) and a score of 1 for responses 3 and 4 (“rather more than usual” and “much more than usual”). Another scoring method in use assigns a score of 0 for response 1 and a score of 1 for response 2-4 for the 18 negative items, and a score of 0 for responses 1 and 2, a score of 1 for responses 3 and 4 for the 7 positive items.
- Total score range from 0 to 28.
- Higher scores indicate a greater probability of a psychiatric distress.
- Total scores that exceed 4 out of 28 suggest probable distress.
- Cut-points and normative data have not been established for the SCI population.

- The GHQ-28’s subscales represent dimensions of symptomatology and not distinct diagnoses.
- As the scales are not independent of each other, the total score has better utility to indicate general psychological disorder than the individual scores do to screen for specific psychological disorders.
- Only one study has assessed the construct validity of the GHQ-28 among SCI populations.
- The GHQ-28 is appropriate for individuals who are at least 11 years of age.
Measurement Property Summary
# of studies reporting psychometric properties: 1
No values have been reported for the reliability of the GHQ-28 for the SCI population.
- Correlation of the GHQ-28 is High with the Clinical Interview Scale (r=0.83).
- With the 0011 scoring scheme, optimum discrimination occurred near GHQ 3/4, giving a specificity of 0.82 and a sensitivity of 0.81.
[Griffiths et al. 1993]
