“…In another study on a larger sample already mentioned (N=1231), females had higher scores on impulse control which was the mediator for depression effects on eating disorder tendencies [16]. In still another sample (N=374), females had lower self-esteem and more "emotional eating problems" and males had greater obesity and overweight problems [20].…”

“…In a meta-analysis on an extremely large sample (N=32,295), PUI was not only correlated with eating disorders (r=.22) but also with body dissatisfaction (r=.16), with drive for thinness (r=. 16) and with dietary restraint (r=.18) [28]. Although these are relatively low correlations, they are highly significant in a sample this size.…”

Anorexia in Adolescents: A Narrative Review

The prevalence of anorexia nervosa has ranged from 27% in non-clinical samples to 85% in samples of adolescents with eating disorders, with twice the prevalence noted in females. Several correlates of anorexia are reported in the recent literature reviewed here including vegetarian diets, personality characteristics such as internalizing and perfectionism as well as behavior problems including impulsivity, dysregulation and being victimized. Comorbidities have included social anxiety, depression and suicidal ideation. In most of these studies, it is not clear which is the primary disorder, as most of the samples are cross-sectional rather than longitudinal. Several of the correlates have also been identified as risk factors including gender, early attachment disturbances, excessive Internet use and negative effects of COVID-19. Potential underlying mechanisms have included involvement of the prefrontal area of the brain based on fMRI and evoked potential research. Fortunately, negative effects of anorexia including decreased body fat mass and bone density as well as lower cortical thickness and less grey matter have been reversed following weight gain. Other effective interventions have included cognitive behavior and dialectical behavior therapy. This narrative review involved entering the terms eating disorders and adolescents into PubMed and PsycINFO. The search yielded 251 papers for the last five years, but following exclusion criteria including case studies and non-English papers, this review is a summary of the research reported in 49 papers. The recent literature on eating disorders in adolescents is predominantly focused on correlates and risk factors for anorexia along with some studies on comorbidities and potential underlying mechanisms for anorexia. Although there are virtually no studies on the effects of anorexia except its effects on body mass and bone mineral density, several intervention studies appear in this literature. Related studies are focused on orthorexia. This narrative review is accordingly divided into sections on the prevalence of anorexia, comorbidities, correlates, risk factors, potential underlying mechanisms and interventions. In a separate section, the smaller literature on orthorexia and drunkorexia is briefly reviewed.

“…Interestingly, despite not receiving medication, patients identified as subtype 1 still had a response rate of 70.27%, whereas those identified as subtype 2 only had a response rate of 45.73%. This discovery could potentially disclose the underlying reasons for the slightly higher effectiveness of antidepressants compared to placebos 7 , as well as provide insight into potential selfhealing mechanisms for MDD 32 .…”

Major depressive disorder (MDD) is highly heterogeneous in terms of responses to treatment, which hinders the improvement in treatment effectiveness and outcomes for MDD. Identifying MDD subtypes associated with treatment responses could inform interventions and facilitate personalized treatment. Here, we sought to identify reproducible MDD subtypes characterized by distinct neurofunctional (i.e., neuroimaging) patterns to delineate heterogeneity in MDD and explored the relationship between subtypes and antidepressant treatment response. We used contrastive variational autoencoders (CVAEs) to identify two distinct MDD subtypes with the REST-meta-MDD II dataset (1660 MDD participants, 1340 HCs). Subtype 1 exhibited increased functional activity in occipital, parietal, temporal, and frontal areas, while subtype 2 showed decreased functional activity in these areas. The number and patterns of MDD subtypes were validated in a further large multi-center dataset (1276 MDD participants, 1104 HCs). Notably, patients with subtype 1 could be considered the "treatment-sensitive" group, with a response rate of over 50% to all antidepressants and a better response to repetitive transcranial magnetic stimulation (rTMS) compared to patients with subtype 2. In contrast, patients with subtype 2 could be characterized as the "treatment-resistant" group, with a response rate of below 50% for most medications. The ensuing MDD-specific features from CVAEs may serve as a neuroimaging biomarker for predicting treatment outcomes for both medication and rTMS treatments. Our study shows that contrastive learning can be used to establish the predictive validity of functional brain signatures — in terms of responses to antidepressant treatment — offering potential new targets for optimizing treatment strategies for treatment-resistant depression, and further lay a path toward higher treatment outcomes.

“…As a central capacity for goal achievement, high self-control is found positively associated with social adaptation, physical and mental health, such as life satisfaction and happiness [ 45 , 47 ]. Conversely, individuals with low self-control are less tolerant of uncertainty [ 48 ], and are more likely to exhibit deviant behaviors, such as internet addiction [ 44 ], eating disorders [ 49 ], antisocial behaviors [ 50 ], and excessive consumption [ 51 , 52 ]. In this way, self-control may be negatively associated with materialistic value orientation [ 53 ].…”

Social network site use and materialistic values: the roles of self-control and self-acceptance

Background While prior studies have established a close association between the use of social network sites (SNSs) and materialistic values, there is limited understanding of the mediating and moderating mechanisms related to important self-related processes, such as self-control and self-acceptance. This paper explores whether and how these factors play a role in comprehending online behavior. One could state that frequent SNS use may pose a risk of virtual addiction, may be related to decreased self-control capacity, and may increase attention to material information on SNS, thereby making it more likely that users affiliate with behaviors associated with materialistic values. In contrast, self-acceptance, as a stable self-process indicating a genuine alignment with one’s true self and the ability to make decisions based on inner needs, may be related with reduced engagement in complex information on SNSs. Consequently, this could serve as a buffer against excessive SNS use and its potential associations with issues of self-control and materialistic values. Methods A total of 706 Chinese college students were surveyed in a cross-sectional study. They completed self-report questionnaires including the WeChat use intensity scale, the Material Value Scale, the Trait Self-control Scale, and the Self-acceptance Questionnaire. A moderated mediation model was examined to test predictions. Results SNS use intensity was positively associated with materialistic values, and self-control partially mediated this association. That is, higher intensity SNS users are more likely lower in self-control, which relates to stronger materialistic values. In addition, the indirect effect through self-control was moderated by self-acceptance, such that this indirect effect was significant only for individuals with low levels of self-acceptance. Conclusions This study reveals that self-acceptance may be a protective factor that helps to mitigate excessive SNS use and its potential effects on self-control and materialistic values. It further suggests that psychological interventions targeting the enhancement of self-acceptance and self-control could hold promise in alleviating the negative association between SNS use and materialistic values.
