Subpopulations of Addictive Behaviors in Different Sample Types and Their Relationships with Gender, Personality, and Well-Being: Latent Profile vs. Latent Class Analysis

Unraveling the complexity and instability of negative emotional eating: A latent transition analysis

The manifestations of emotional eating are complicated, encompassing both over- and under-eating. However, little is understood about how emotional over- and under-eating constitute individuals' eating patterns and how these patterns change over time. Employing latent transition analysis, a longitudinal and person-centered approach, this study examined the patterns and stability of emotional eating. Over six months, 755 participants completed two waves of self-reported questionnaires. Results revealed four distinct latent profiles: Low Emotional Eaters (11.5-15.8%), Emotional Eating-Undereaters (31.1-40.5%), Emotional Eating-Overeaters (15.9-18.3%), and Combined-Emotional Eaters (29.7-37.2%). Approximately 50% of participants in each profile maintained their behavioral patterns over time, with transitions often shifting towards Combined-Emotional Eaters. Individuals in the profile of Emotional Eating-Overeaters exhibited the highest level of anxiety, depression, stress, and disordered eating. Gender, self-esteem level, and self-esteem instability were associated with profile membership and transition probabilities. These findings highlight the presence of distinct and relatively unstable patterns of negative emotional eating, indicating the potential distinction between trait and state emotional eating. Recognizing these inherent characteristics is crucial for future studies and intervention programs addressing negative emotional eating.

Problematic overstudying, Big Five personality, and music performance anxiety: associations with well-being and GPA

BACKGROUND

Problematic overstudying is a compulsive and pathological overinvolvement in studying leading to harm and considerable functional impairments. It is conceptualized as "study addiction," a precursor to work addiction. It has been investigated within the addictive behaviours framework in general populations of students for over a decade. A previous study analysed the problem among young musicians as a particularly vulnerable group. It found some important differences in potential personality risk factors among music academy students compared to general populations of students and showed an important role of social anxiety. The current study aimed to validate these findings in a separate larger sample and extend them by investigating the role of music performance anxiety (MPA).

PARTICIPANTS AND PROCEDURE

The study was conducted among 213 students of music academies. Valid and reliable measures of study addiction, MPA, Big Five personality and well-being were used.

RESULTS

The results showed that MPA played a similar role as social anxiety in terms of being a predictor, mediator, and moderator of the main replicated effects supporting the hypothesised mechanisms regulating study addiction. However, extraversion was not associated with study addiction in multiple hierarchical regression analysis, but conscientiousness and neuroticism were. Study addiction was associated with indicators of decreased well-being, above and beyond MPA, and personality.

CONCLUSIONS

These results show that MPA plays an analogous role to social anxiety and that the role of Big Five personality in study addiction among young musicians requires further investigation due to inconsistent findings.

The Modified Yale Food Addiction Scale May Be Simplified and Diagnostically Improved: The Same Prevalence but Different Severity and Risk Factors of Food Addiction among Female and Male Students

The Yale Food Addiction Scale (YFAS) is the most commonly used scale for measuring food addiction (FA). The previous approach to the YFAS and its subsequent versions assumed dichotomization of items, separating addiction symptoms and clinical significance items, and factorial validity testing on a subset of items. In this paper, we discuss the drawbacks associated with these procedures. In addition, we present a different analytical approach to investigate the validity of the modified YFAS (mYFAS) along with an alternative scoring method that overcomes limitations related to the previous approach. After establishing the structure of the mYFAS, we investigated the potential antecedents and consequences of FA separately for men and women. The sample consisted of 1182 Polish undergraduate students (613 women, 559 men, 10 missing values on gender) with a mean age of 20.33 years (SD = 1.68; range: 18–36). They were asked to complete self-report questionnaires measuring FA, personality traits (Big Five), self-esteem, narcissism, self-efficacy, social anxiety, loneliness, and well-being indicators. Due to the low content, factorial, and clinical validity, the first three items were excluded from the Polish version of the mYFAS. The six-item mYFAS demonstrated measurement invariance, allowing for meaningful comparisons between genders and yielded almost identical prevalence rates for men and women. The hierarchical multiple regression analysis showed that, narcissism, and social anxiety predicted FA in both genders, whereas important gender differences in antecedents were also noted. In addition, FA was associated with body mass index (BMI) and most of the well-being indicators, even after controlling for relevant variables. The findings suggest that our modified analytical approach allows researchers to measure FA using a valid, useful, and simple tool.

Compulsive Study Behaviors Are Associated with Eating Disorders and Have Independent Negative Effects on Well-Being: A Structural Equation Model Study among Young Musicians

Compulsive overworking and eating disorders (EDs) show considerable similarities in terms of risk factors (e.g., rigid perfectionism), clinical manifestation (e.g., excessive controlling behaviors), and consequences (e.g., physical exhaustion and depression). This study aimed to examine the hypotheses that compulsive study behaviors (conceptualized as study addiction) are related to EDs and that they have independent negative effects on well-being among young musicians, who constitute a highly vulnerable population for these types of problematic behaviors. The relatively high prevalence of study addiction and its pronounced negative relationship with psychosocial functioning make it a pending challenge for sustainable education. A total of 255 students from various music academies in Poland took part in the study. The Bergen Study Addiction Scale, assessing compulsive studying (conceptualized as addictive behavior), the Eating Attitude Test-26 (EAT-26), the Perceived Stress Scale, the Hospital Anxiety and Depression Scale, and the quality-of-life measure were used. A structural equation model was investigated. Study addiction was positively related to the general factor of EDs and the social pressure component. Both problematic behaviors showed negative and independent effects on the well-being of young musicians. EDs may be 8 to 16 times more prevalent among the students of music academies who are addicted to studying than among the general population. About 80% of those students showing all seven symptoms of study addiction exhibited at least mild depression, while more than half had clinically significant levels of depression. Almost 90% had clinically significant levels of anxiety. Without addressing co-occurring study addiction and eating disorders, including their commonalities and idiosyncrasies, their prevention and treatment cannot be effective and it will substantially affect the sustainability of education and work.
