General Self-Efficacy Scale:
Scoring and Interpretation
The General Self-Efficacy Scale (GSE) is a ten-item self-report measure of broad confidence in coping with difficult situations, scored by summing items coded 1 to 4 into a total from 10 to 40 (Schwarzer & Jerusalem, 1995). Because no item is reversed, General Self-Efficacy Scale scoring turns on other decisions: labeling the optional 1 to 4 mean, explaining why no clinical cut-off exists, checking translated versions before comparing scores, and computing a total only if all ten answers are present.
What the GSE Measures
The ten-item General Self-Efficacy Scale (GSE) assesses broad confidence in the ability to handle difficult situations and solve problems. It captures a generalized belief about capability rather than perceived competence in a specific task, such as medication adherence or exercise behavior. The original German version was developed in 1979 (Jerusalem & Schwarzer, 1981).
Schwarzer and Jerusalem’s GSE has been studied in stress, health-behavior and adjustment research, and the US National Cancer Institute describes its use in research on coping with daily demands and adaptation to stressful events. When behavior-specific efficacy is the primary hypothesis, a tailored domain-specific measure may be conceptually more appropriate.
Structure of the GSE
- Items: ten items, all scored in the same positive direction, with response categories coded 1 to 4.
- Reverse-scored items: none in the commonly used 10-item GSE.
- Subscales: none.
- Total: the sum ranges from 10 to 40, and higher totals indicate greater generalized self-efficacy. An optional item mean on the 1 to 4 metric must be clearly labeled.
- Recall period: none is inherent to the measure, which captures an ongoing self-belief.
- Versions: the established 10-item form and translated adaptations. Exclude adaptations that use different anchor coding until their scoring has been verified.
The instrument itself is available from Ralf Schwarzer’s scale website and the National Cancer Institute (NCI) self-efficacy constructs page.
How to Score the GSE
- Check that items gse1 to gse10 are coded 1 to 4 according to the administered version.
- Sum all ten responses into gse_total, with a range of 10 to 40. Do not reverse score.
- The example requires all ten responses. The source material does not establish a universal missing-item prorating rule, so document any planned method.
- Optionally present gse_mean as gse_total divided by 10 (range 1 to 4), clearly distinguished from the canonical sum.
COMPUTE gse_total=SUM.10(gse1,gse2,gse3,gse4,gse5,gse6,gse7,gse8,gse9,gse10).
EXECUTE.
COMPUTE gse_mean=gse_total/10.
EXECUTE.data$gse_total <- rowSums(data[paste0("gse",1:10)],na.rm=FALSE)
data$gse_mean <- data$gse_total/10Interpreting GSE Scores
| Score band | Interpretation |
|---|---|
| 10 to 40 | Continuous generalized self-efficacy total |
| 10 | Theoretical lowest score |
| 40 | Theoretical highest score |
| Universal clinical impairment cut-off | Not established by the original scale |

Higher scores indicate stronger perceived general coping capability. The GSE is not a disorder screen, and there are no standardized diagnostic bands in the original scale. Report the sample mean, SD and quantiles rather than inventing universal low, medium and high categories.
Do not confuse generalized self-efficacy with task-specific self-efficacy, and do not equate scores across translated versions without measurement equivalence checks.
Psychometric Properties
| Property | Published finding | Source |
|---|---|---|
| Internal consistency | Across 25 countries (N = 19,120), Cronbach’s α ranged from .75 to .91, with most samples in the high .80s | Scholz et al. (2002) |
| Convergent validity | Theory-consistent associations with coping and adaptation to demanding events | Schwarzer & Jerusalem (1995); NCI |
| Structural validity | Commonly treated as a single generalized efficacy construct | Schwarzer & Jerusalem (1995) |
| Cross-cultural evidence | Psychometric evidence exists in multiple countries and languages; equivalence should be checked in each new sample | Scholz et al. (2002) |
| Diagnostic performance | Not a clinical diagnostic test; no sensitivity or specificity criterion | Schwarzer & Jerusalem (1995) |
These are source-specific results and cannot be assumed to hold as reliability or accuracy estimates in a new sample.
Using the GSE in a Study
Use the GSE total as a continuous predictor or outcome in health psychology and educational research. Common options are Multiple Linear Regression, Linear Mixed Models (Multilevel Modeling) for repeated waves, and Structural Equation Modeling (SEM), depending on the study design and causal assumptions. Report the actual sample reliability from Reliability Analysis (Cronbach’s Alpha) and the item-level missingness.
For cross-language comparisons, examine invariance of the underlying factor model with Measurement Invariance, because different translations may not have perfectly equivalent item thresholds. There is no generally established minimal clinically important difference or clinical cut-off from the standard development paper.

Reporting the GSE
Generalized perceived self-efficacy was assessed using the ten-item General Self-Efficacy Scale (GSE; Schwarzer & Jerusalem, 1995). Responses were coded from 1 to 4 and summed to create a 10 to 40 total score, with higher scores reflecting greater self-efficacy. Internal consistency was [α = XX] in the present sample. Missing values were managed as [method].

Frequently Asked Questions
What is the scoring range of the GSE?
Ten items coded 1 to 4 yield a total between 10 and 40.
Does the GSE contain reverse-coded items?
No. The conventional 10-item form scores all items in the same direction, so the total is a plain sum.
Is the GSE a diagnostic scale?
No. It measures perceived general ability to cope with challenging tasks, not a psychiatric disorder, and it has no sensitivity or specificity criterion.
Can I average the 10 items instead of summing them?
Yes, if the resulting 1 to 4 mean metric is clearly labeled and not mistaken for the 10 to 40 sum.
