Eating Attitudes, Body Appreciation, Perfectionism, and the Risk of Exercise Addiction in Physically Active Adults: A Cluster Analysis
Background/Objectives: Although regular physical exercise is protective for health, excessive engagement can contribute to the development of addiction. Further, the co-occurrence of exercise addiction (EA) and disordered eating (DE) is very frequent among athletes with several common risk factors. Our study focused on the associations between exercise addiction, eating attitudes, body appreciation, and perfectionism in a sample of physically active adults. Methods: Using a sample of Hungarian adults who were regular exercisers (n = 205, aged 18–70 years, mean age = 30.59 years; 77.1% females), cluster analysis was applied to identify participants’ profile according to their level of EA, DE attitudes, body appreciation, and dimensions of perfectionism. Results: Healthy exercisers had the second lowest level of EA and highest level of body appreciation, and they were not prone to DE (31.22%). Another cluster had a relatively low risk of EA but were potentially prone to DE, with poor body appreciation and a medium level of socially prescribed and other-oriented perfectionism (29.8%). Third, a group of exercisers was characterized by the highest risk of both EA and DE, who also reported relatively high levels of personal standards and organization (25.36%). Finally, those with the second highest risk of EA with a high tendency for dieting and bulimia and poor body appreciation were prone to socially prescribed and other-related perfectionism (13.66%). Conclusions: Symptoms of exercise addiction are not necessarily pathological, but they can serve as signals for the overuse of sports and undue achievement orientation, particularly when being associated with disordered eating attitudes.

Dropout Intention among University Students with ADHD Symptoms: Exploring a Path Model for the Role of Self-Efficacy, Resilience, and Depression
Major conceptual models of ADHD and learning disabilities underscore the adverse effects they have on academic performance and dropout from university. Therefore, identifying psychological risks and protective factors can aid in managing academic challenges and decreasing dropout rates. In this cross-sectional study, a sample of 395 Hungarian college students (66.6% female, mean age 23.72 years [SD = 3.87]) responded to an online survey including the Adult ADHD Self-Report Scale, Beck Depression Inventory, General Self-Efficacy Questionnaire, Academic Resilience Scale, and the Higher Education Retention Questionnaire. Path analysis indicated that depression and academic resilience mediate the relationship between ADHD symptoms and dropout intention, while self-efficacy moderates this association. The findings highlight the critical role of psychological factors in shaping academic dropout for college students with ADHD symptoms. Enhancing academic resilience and self-efficacy may help mitigate the negative impact of ADHD symptoms on college retention.

Orthorexic Tendency in Light of Eating Disorder Attitudes, Social Media Addiction and Regular Sporting Among Young Hungarian Women
This study examined a set of background psychological and other variables of orthorexic (ON) tendency in a sample of young women with special interest in healthy lifestyle. The sample consisted of female young adults (N = 310; aged 18-35 years; mean age = 24.3 years; SD = 4.97 years) who were recruited through social media health sites. Besides Orthorexia Nervosa Questionnaire (ORTO‑15), BMI, regular sporting activity, the following scales were used: Eating Disorder Inventory (EDI, drive for thinness, ineffectiveness and maturity fears); Bergen Social Media Addiction Scale (BSMAS); and The Proactive Coping Inventory. In this sample, 37.7% were at risk for ON. Eating disorder attitudes, regular sporting and social media addiction were the most relevant predictors of orthorexic tendency with drive for thinness being the strongest contributor (β = 0.54, p < 0.001). For young women with a special interest in healthy lifestyle, drive for thinness together with regular sporting, ON tendency may serve as a tool for achieving their goal. Social media addiction and other psychological problems (feeling of ineffectiveness or maturity fears) can also contribute to orthorexic rendency. It would be important to ask for support from qualified health professionals when changing nutritional practices.

The role of achievement attribution in the associations between parent–child communication and psychological well-being among adolescents: A mediation analysis
Background: Previous studies have explored the association between parenting style and offspring’s psychological well-being, and the association between offspring’s achievement attribution pattern and psychological well-being. However, little is known about the role of offspring’s achievement attribution in the relationship between parenting and offspring’s psychological well-being. We aimed to find the role of adolescents’ achievement attribution pattern in the relationship between parent–child communication quality and adolescents’ mental health. Methods: A cross-sectional analysis was conducted on 2,725 adolescents aged from 9 to 18 years who are participating in the China Family Panel Studies. Participants supplied demographic information and completed a series of psychological scales including the Center for Epidemiologic Studies Depression scale, an adapted version of the Parental Bonding Instrument, an achievement attribution scale, and single-item measures of subjective well-being and subjective interpersonal popularity. Results: Linear regression analysis revealed that after controlling for demographic factors good parent–child communication negatively correlated with depression symptoms, and positively associated with subjective well-being and subjective interpersonal popularity. Next, mediation analysis found that internal attribution of achievement partly mediated the effects of parent–child communication quality on adolescents’ depression, subjective well-being, and subjective interpersonal popularity. The result was robust after controlling demographic variables. Conclusions: An internal attribution pattern of achievement partially accounted for the associations between parent–child communication quality and adolescents’ psychological outcomes including depression, subjective well-being, and subjective interpersonal popularity. Future interventions for adolescents’ mental health promotion can target parent–child communication and adolescents’ positive achievement attribution pattern.

Real World Challenges in Delivering Consumer Directed Care to Enhance Nursing Home Residents’ Well Being
The aim of this study was to use the ADKAR model of organizational change to gain an understanding of why a training program designed to equip staff with the skills to provide a Consumer Directed Care (CDC) model in nursing homes produced little change in the outcome variables, including resident quality of life. We collected and analyzed various forms of site-specific data including CDC implementation plans developed by staff trained in 21 facilities, and their training facilitators’ records. Staff trained in the principles of CDC produced well-developed, facility-specific plans to introduce a CDC model of care, yet they faced many barriers to the implementation of these plans. These barriers were spread across multiple stages of the ADKAR model and included staff turnover (including managers), lack of engagement by management, lack of or inconsistent availability of a CDC champion, and disruptions to the training program. We identified several organizational factors contributing to the failure of the training program to produce anticipated changes. Without organizational commitment and full management support, attempts to implement CDC training programs are likely to fail, leading to negative consequences for residents’ autonomy and control over how they are cared for.

Reduced Peripheral Nerve Conduction Velocity is Associated with Alzheimer’s Disease: A Cross-Sectional Study from China
Purpose: Elderly individuals with degenerative diseases of the central nervous system are more likely to develop peripheral neuropathy; however, research is limited as to whether the decline in peripheral nerve conduction can be used as a biomarker of Alzheimer’s disease (AD). Patients and Methods: This study enrolled 74 patients with mild cognitive impairment (MCI), 21 with AD, and 82 healthy elderly individuals. All participants underwent a peripheral nerve conduction and neuropsychological evaluation. Nicolet EDX was used to assess peripheral nerve conduction in the limbs and comparisons were made between the three cognitive groups. Furthermore, the relationship between peripheral nerve conduction and cognitive function was investigated. Results: A ladder-shaped difference was found in the median (p < 0.001) and common peroneal (p < 0.001) motor nerve velocity, with the control group > MCI group > AD group, even after controlling for variables. The median motor nerve amplitude in the AD group was lower than that in the control group (P = 0.017). After controlling for age, sex, education, and height, the median motor nerve velocity was positively correlated with the Montreal Cognitive Assessment (r = 0.196, p = 0.015), and the common peroneal motor nerve velocity was positively correlated with verbal fluency task-idioms (r = 0.184, p = 0.026). The median (AUC: 0.777, p < 0.001) and common peroneal motor nerve velocities (AUC: 0.862; p < 0.001) were significantly associated with the diagnosis of AD. The accuracy rate of these two motor nerve velocities to predict AD was 51.5%. Conclusion: Our study found that peripheral motor nerve velocity may correlate with early cognitive impairment in AD. However, the accuracy of different cognitive classifications and the value of early diagnosis are not ideal when peripheral motor nerve velocity is used alone. Whether peripheral nerve function can be used as a marker for early diagnosis of AD needs further clarification but provides a new possibility for the future of biomarker research.
