Basic Mood Scale (Grundstimmung - GS) reflects the perception of the general emotional background, mood stability, and ways of reacting to internal and external influences. It is oriented towards assessing how stable, cheerful, or, conversely, depressed and tense the emotional state appears to be.
This scale touches upon deep-seated aspects of personality related to the direction of aggression and the method of emotional processing of experience. One pole of the scale is hypomanic, while the other is depressive, with a wide spectrum of states possible in between.
The scale measures not so much short-term mood swings but rather a stable mood that becomes a habitual style of emotional response. Thus, the scale allows for an assessment of how pronounced balance, a tendency toward self-blame, or, conversely, the active expression of feelings—including irritation—is in one's perception.
At the hypomanic pole, cheerfulness, energy, independence, and low reflexivity are noted. There is a tendency toward the direct expression of feelings and a predominance of action over analysis. At the depressive pole, depression, a tendency toward doubt and self-criticism, withdrawal, as well as the presence of internal conflicts and deep analysis are observed.
The Basic Mood Scale is linked not only to emotionality but also to the direction of aggression:
- At high values (depressive pole), aggression is more often directed inward—in the form of self-blame, excessive reflection, and feelings of guilt.
- At low values (hypomanic pole), it is directed outward, which can manifest as irritability, quick temper, or a tendency toward dominance.
It is important to understand that a high level of control does not always indicate personality maturity: sometimes it can be a way to reduce anxiety or internal tension. Similarly, a low level can be a manifestation not only of lightheartedness but also of flexibility, creativity, and freedom from excessive rigidity. Everything depends on the context and the combination with other scales.
Application of the scale in different versions of the inventory:
- In the "Self" version, the scale shows how a person perceives themselves emotionally: balanced, depressed, or, on the contrary, lively and sometimes unstable.
- In the "Him" / "Her" versions, it shows how the emotional state of another is perceived: rather withdrawn and anxious or cheerful and easily excitable.
Interpretation of Results
To ensure standardized interpretation of the Giessen Personality Inventory results, raw scores are converted into T-scores. This linear transformation process brings the distribution of scores for each scale to a single metric system characterized by a mean (M) of 50 and a standard deviation (SD) of 10. This allows for a normative comparison of individual indicators with a reference sample and unifies the interpretation of the intensity of various personality characteristics, thereby facilitating inter-scale comparison and clinical assessment of the personality profile.
Interpretation of results on the Basic Mood Scale requires caution: both excessive depression and excessive emotional activity can be signs of either adaptation or internal disharmony—depending on the other scales in the profile.
Low values are associated with the perception of emotional activity, vigor, and energy. Such a mood may be accompanied by a tendency not to dwell on negative experiences, direct expression of irritation, reduced reflection, and high independence in the emotional sphere. However, in extreme manifestations, emotional difficulties may be underestimated, or there may be insufficient sensitivity to internal conflicts.
Average values reflect a balanced perception of the emotional state—with a moderate tendency toward self-analysis and the ability to notice one's own emotional fluctuations. This level indicates relative stability of the emotional background and an adequate attitude toward experienced difficulties.
High values are characterized by perceptions of reduced vital energy, the presence of anxious or depressed states, increased self-criticism, and a tendency toward reflection and doubt. Restrained expression of aggression, directed inward rather than outward, may also be observed. In some cases, such a perception is accompanied by a sense of emotional vulnerability and internal tension.
