Core Affect Self-Report Measure (EmoS-15) Test

People seeking a structured reflection on their reported emotional experience may use the Core Affect Self-Report Measure (EmoS-15) Test to compare different qualities of feeling within one profile. A core affect questionnaire can be useful when someone wants language for noticing emotional energy, unease, sadness, or enthusiasm without reducing the experience to a single mood label.

What This Assessment Explores

Feelings vary in pleasantness and activation: someone may feel depleted and sad, internally strained, or positive and energized. The items use familiar terms such as pleasure, anxiety, depression, nervousness, inspiration, emptiness, sadness, joy, regret, yearning, and admiration. In this EmoS-15 questionnaire, the profile reports the level of each dimension independently.

The result is organized around these three displayed dimensions:

• Low-Arousal Negative Affect (5-25) measures negative emotion with reduced energy; higher scores may suggest dejection, apathy, or sadness. Low 5-12; Moderate 13-18; High 19-25.
• Tension (5-25) measures internal tension and anxiety; higher scores may suggest worry, stress, or discomfort. Low tension 5-11; Moderate tension 12-18; High tension 19-25.
• High-Activation Positive Affect (5-25) measures energetic, alert positivity; higher scores may suggest joy, enthusiasm, or activity. Low 5-12; Moderate 13-19; High 20-25.

Methodology and Scientific Basis

Each statement uses a five-point response scale, moving from not at all or does not describe me to completely. The respondent gives a graded judgment rather than a yes-or-no answer, allowing the result to represent intensity. Slight differences in wording do not change the central task: rate how well each feeling describes the respondent.

The online questionnaire is conceptually consistent with the three-dimensional EmoS-15 structure described by Lyusin (2019) and with Russell’s (2003) core-affect model, which describes emotional experience through pleasantness and activation. This relationship concerns shared structure and concepts only: the online core affect self-report test is not presented as the published EmoS-15 instrument, an adaptation of it, or a separately validated version.

Interpretation compares each score with its displayed band, with higher values indicating greater reported intensity of that dimension. The online profile supplies descriptive bands rather than population norms or clinical cutoffs. Self-report results can shift with the emotional context of responding, circumstances, attention, and willingness to answer candidly, so this profile is best used as a focused snapshot for further self-reflection.
