This study introduces the Self-Invalidation Due to Emotion Scale (SIDES), a new tool to measure negative self-evaluation of emotions. The SIDES is a reliable and inclusive measure for people with and without mental illness diagnoses.
Area of Science:
- Psychology
- Clinical Psychology
- Psychometrics
Background:
- Self-stigma, or internalized negative self-evaluation, is often linked to mental health diagnoses.
- Existing measures may exclude individuals without diagnoses who still negatively evaluate their emotions.
- Self-invalidation due to emotion is defined as the negative self-evaluation of one's own emotions.
Purpose of the Study:
- To develop and validate a novel measure of self-invalidation due to emotion.
- To differentiate self-invalidation due to emotion from self-stigma due to mental illness and perceived emotion invalidation.
- To assess the psychometric properties and predictive validity of the new scale.
Main Methods:
- Development of the Self-Invalidation Due to Emotion Scale (SIDES) through expert review and factor analyses (Studies 1-3).
- Validation of the 10-item SIDES in college and community samples, assessing test-retest reliability (Study 4).
- Examination of SIDES' predictive validity for emotion dysregulation, reactivity, expressivity, and controllability, and its association with mental illness symptoms (Studies 4-5).
Main Results:
- The 10-item SIDES, with subscales for high and low emotional experience, demonstrated strong psychometric properties.
- Self-invalidation due to high emotional experience predicted greater emotion dysregulation and reactivity.
- Self-invalidation due to low emotional experience predicted less emotional reactivity and greater perceived control.
- In individuals with a history of mental illness, self-invalidation due to high emotional experience predicted borderline personality pathology symptoms and distress.
Conclusions:
- The SIDES is a psychometrically sound and inclusive measure for assessing self-invalidation due to emotion.
- The scale is relevant for predicting distress and maladaptive emotional tendencies in diverse populations.
- Findings highlight the importance of addressing self-invalidation in both clinical and non-clinical samples.
