Body image is a multifaceted construct that includes attitudinal and perceptual components, but its attention has mainly been focused on the facet of body dissatisfaction. The present longitudinal study extended the validation of a multifacet attitudinal questionnaire, the Body Uneasiness Test (BUT), against perceptions of body shape and weight. A convenient sample of adolescents took part in a 2-year unbalanced panel study (5 waves). The participants completed the BUT questionnaire and selected their perceived actual, ideal, and reflected body figures along the Contour Drawing Rating Scale; ideal/actual and ideal/normative body mass index discrepancies were also included. After replicating the expected five-factor structure of the BUT items, results from confirmatory factor analysis revealed that the five BUT scales loaded on an attitudinal dimension, whereas the perceived body figures and the discrepancy indices were on a perceptive domain. Such a two-domain structure of body image measures showed gender and seasonal (1-year) measurement invariance, whereas longitudinal 6-month and 18-month invariance partially failed. Overall, the present findings support the validity of the Body Uneasiness Test in adolescence, further demonstrating a preliminary multidimensional structure of body image onto which attitudinal and perceptual body image-related measures were projected.

Purpose: This longitudinal study examined how pre-intervention psychological health helps predict bariatric surgery (BS) success as percentage of expected body mass index loss (%EBMIL) over shorter to longer periods. Methods: Adult candidates for BS (N = 334, 67.4% females) completed the Symptoms Checklist 90 (SCL-90) questionnaire; on average, 11 months occurred between the pre-surgery psychological evaluations and the bariatric intervention. We explored the factor structure of the SCL-90 items and inspected how SCL-90 empirical factors compared with SCL-90 scales and general indices predicted %EBMIL at 3–6-month, 1-year, and 2-year follow-up occasions, adjusting for gender, pre-intervention use of antidepressants and actual and ideal BMIs. Results: Factor analysis combined the 90 items into 8 factors, which partially replicated the expected item structure. The SCL-90 empirical factors (but not the SCL-90 scales and indices) contributed to predict BS success. In fact, the Relational Distress factor directly protected from weight regain at 1-year follow-up, indirectly via 1-year %EBMIL at the 2-year follow-up, when it further strengthened the impact of the empirical factor of Generalized Anxiety on the 2-year BS outcome. The results also evidenced a cascade effect of the pre-surgery actual BMI across time as well as unique and direct effects of pre-surgery use of antidepressants and perceived ideal BMI on the 2-year outcome. Conclusions: SCL-90 empirical factor scores for obese patients are more efficient in anticipating BS success compared with original scale scores. They reveal that relational distress and anxiety are risk factors for postoperative weight loss, in addition to pre-intervention actual BMI, antidepressant therapy, and perceived ideal BMI. Level of evidence: III, well-designed cohort.

The assessment of anxiety symptoms in children and adolescents requires a valid and reliable single instrument able to detect various anxiety symptoms early and systematically collect data from other informant such as parents. The present study aimed to test the one-factor structure of the SCAS-P-8 and to examine its psychometric properties and invariance across sex and age in an Italian sample of 769 parents of children and adolescents aged 3–18 years (50.8% females). Confirmatory factor analysis confirmed the one-factor structure of the SCAS-P-8, which showed good reliability and invariance by sex and age. When examining mean differences by sex and age, results showed that female schoolchildren had higher anxiety scores than males and other age groups. A strong correlation with emotional problems demonstrated convergent validity, while discriminant validity resulted from the weak correlations with externalizing symptoms and relationship problems with peers. Overall, findings support the SCAS-P-8 as a valid brief instrument to assess anxiety symptoms in children and adolescents for clinical and research purposes and demonstrate its invariance across sex and age.

Fear of Missing Out (FoMO) is a salient factor influencing adolescents' mental health in the digital age. This two-wave longitudinal study examined whether self-esteem mediates the association between emotion regulation difficulties and FoMO over a five-month interval, while controlling for baseline levels of FoMO and self-esteem, as well as age and sex. A total of 1311 adolescents (57.5% female; M = 16.4, SD = 1.1) completed self-report measures of FoMO, self-esteem (RSES), and the Difficulties in Emotion Regulation Scale-Short Form (DERS-SF). Regression analyses showed that the DERS Strategies subscale, reflecting limited access to effective emotion regulation strategies, was the only dimension that uniquely predicted FoMO at follow-up after controlling for baseline levels. Structural equation modeling supported a mediation model, with a significant indirect effect of emotion regulation difficulties on FoMO at follow-up via self-esteem. The final model demonstrated good fit and explained 55% of the variance in FoMO at follow-up. Findings indicate that difficulties accessing adaptive regulation strategies may be associated with lower self-esteem over time, which in turn relates to higher FoMO. Interventions targeting emotion regulation and self-esteem may help mitigate FoMO-related distress in adolescence.
