Self-inefficacy's impact on well-being indices in students self-identifying with cluttering characteristics

•Participant with self identified cluttering characteristics (SICC) were studied.•SICC and self- inefficacy were associated with more negative well- being.•Self-inefficacy was associated with less positive well -being.•Self-inefficacy moderated the association between SICC and well-being. Cluttering, a fluency disorder characterized by fast and irregular speech patterns, receives relatively limited research attention. Consequently, the association between cluttering and measures of well-being remains unexplored. In contrast, stuttering, another fluency disorder, has been associated with anxiety and depression. The present study examines whether an individual's experience of cluttering characteristics is related to alterations in both positive and negative measures of well-being. To achieve this, we assessed the relationship between Self-Identified Cluttering Characteristics (SICC) and measures of well-being in a sizeable sample of 1201 university students. Our main objective was to explore the potential impact of self-inefficacy on the association between SICC and well-being. Consistent with prior research, participants identified themselves as having cluttering characteristics (SICC) or no-cluttering characteristics (SINCC) based on a verbal and written explanation of the disorder. They also completed questionnaires on psychological well-being indices and self-inefficacy. In total, 276 respondents identified themselves as having cluttering characteristics. In regression models, both SICC and self-inefficacy were predictive of greater negative well-being, increased depressive symptoms, and heightened psychosomatic symptoms. Interestingly, ADHD diagnosis was associated with less negative well-being. Positive well-being indicators (positive future orientation and subjective happiness) were solely predicted by self-inefficacy. Supporting these findings, supplementary regressions including only 56 SICC participants who reported being treated for cluttering yielded similar results. Utilizing Hayes's PROCESS computational procedures to test moderation revealed that self-inefficacy significantly moderated the association between SICC and negative well-being (depressive symptoms) as well as the association between SICC and positive well-being (positive future orientation). The findings underscore alterations in well-being among individuals who identify themselves as experiencing cluttering characteristics. Primarily, heightened negative well-being was noted in tho
