Affective Instability: Impact of Fluctuating Emotions on Regulation and Psychological Well-Being

Abstract

Previous research has focused on understanding the occurrence of intense and fluctuating emotions and the ability to manage these emotions and affective states. These phenomena have been, respectively, labeled as affective instability and emotion regulation and have been studied among individuals diagnosed with borderline personality disorder (BPD), attention-deficit/hyperactivity disorder (ADHD), bipolar disorder (BD), and post-traumatic stress disorder (PTSD). Previous findings suggest that affective instability may be associated with poorer psychological well-being. The present study aims to investigate the general tendency of affective instability and capacity for emotional regulation among college students, regardless of a previous psychological diagnosis, and to understand the relationship between these processes and psychological well-being. Three questionnaires were administered to measure levels of affective instability, the ability to manage fluctuating affective states, and overall psychological well-being. The findings suggest that (1) individuals with diagnoses experience affective lability and difficulty regulating emotions at a greater rate than those without, (2) higher affective lability scores are consistent with more significant emotion dysregulation and lower overall psychological well-being, and (3) scores on the Affective lability Scale (ALS) and the Difficulties in Emotional Regulation Scale (DERS) are reliable predictors of one’s estimated Global Assessment of Functioning (GAF) scores. Although causation has not been established, the evidence suggests that individuals with diagnoses experience greater difficulty in regulating their emotions, have greater affective lability, and experience diminished psychological well-being and day-to-day functionality. Certain anecdotal evidence suggests that emotional lability can be endogenous and affect multiple aspects of an individual’s social, occupational, and personal life. By revising the existing literature and the present findings, the authors provide insights into the significance of endogenous factors in the context of affective lability and offer suggestions for future research.
