In this study positive affective states, experienced by users of a one-hour learning program, in a hypermedia learning environment were assessed. It was expected that a positive mood would occur during learning that would be correlated with high training/learning success. Furthermore, the experience of flow was used to indicate whether the challenges and skills were balanced. The results showed that the users of the training program were put into a positive mood. About a quarter of the users experienced flow. Positive moods were associated with higher training success and positive affect was correlated with total knowledge and content knowledge. An association between flow and training success was not observed. The perceived probability of success did not influence learning but a high perceived probability of success was considered as comparably more pleasant than a low perceived probability of success. The results are discussed in the context of self-directed learning.A central task of educational research is to describe and explain how learning technologies can be successfully used in school, university and business. So far the focus has been predominantly on cognitive aspects. Motivational aspects such as learning motivation, mood and other positive states that occur during hypermedia learning have only recently been considered (eg, Chan and Ahern, 1999;Konradt and Sulz, 2001). This study concentrates on positive states occurring during hypermedia learning, how anticipation of success affects the actual learning success, and whether the challenges of the learning system correspond with the skills of the user. Learning with hypermediaIn recent years, it has been repeatedly emphasised that hypermedia systems can deliver and provide information more efficiently than traditional media. Hypermedia allow depicting complex and not clearly defined domains, integrating information with the aid of varying ways of coding, re-conceiving issues in the context of different disciplines

The results confirm gender differences in distinctive facets of body image concern and its prediction. The relevance of increase in body image concern in adolescents is underlined by its association with eating concern in both genders. Further explanatory variables for change in body dissatisfaction should be examined in future studies. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2017; 50:139-147).

BackgroundCompulsive exercise (CE) is a frequent symptom in patients with eating disorders (EDs). It includes, in addition to quantitatively excessive exercise behaviour, a driven aspect and specific motives of exercise. CE is generally associated with worse therapy outcomes. The aims of the study were to compare self-reported quantity of exercise, compulsiveness of exercise as well as motives for exercise between patients with anorexia nervosa (AN), bulimia nervosa (BN) and healthy controls (HC). Additionally, we wanted to explore predictors of compulsive exercise (CE) in each group.MethodsWe investigated 335 female participants (n = 226 inpatients, n = 109 HC) and assessed self-reported quantity of exercise, compulsiveness of exercise (Compulsive Exercise Test), motives for exercise (Exercise Motivations Inventory-2), ED symptoms (Eating Disorder Inventory-2), obsessive-compulsiveness (Obsessive-Compulsive Inventory-Revised), general psychopathology (Brief Symptom Inventory-18) and depression (Beck Depression Inventory-2).ResultsBoth patients with AN and BN exercised significantly more hours per week and showed significantly higher CE than HC; no differences were found between patients with AN and BN. Patients with EDs and HC also partly varied in motives for exercise. Specific motives were enjoyment, challenge, recognition and weight management in patients with EDs in contrast to ill-health avoidance and affiliation in HC. Patients with AN and BN only differed in regard to exercise for appearance reasons in which patients with BN scored higher. The most relevant predictor of CE across groups was exercise for weight and shape reasons.ConclusionsExercise behaviours and motives differ between patients with EDs and HC. CE was pronounced in both patients with AN and BN. Therefore, future research should focus not only on CE in patients with AN, but also on CE in patients with BN. Similarities in CE in patients with AN and BN support a transdiagnostic approach during the development of interventions specifically targeting CE in patients with EDs.Electronic supplementary materialThe online version of this article (10.1186/s40337-018-0202-6) contains supplementary material, which is available to authorized users.

Objective: This prospective study explored bidirectional associations between attachment quality towards mother, father, and peers and disordered eating among a large population-based sample of boys and girls in the transition from preadolescence to adolescence. Specifically, we examined whether insecure attachment relationships emerged as a risk factor for or as an outcome of disordered eating.Method: A population-based sample of 904 adolescent girls and boys was assessed four times, at baseline (T1; M age = 10.8 years) and at 2-, 4-, and 6-year follow-up (T2, T3, and T4). Prospective data were analyzed using cross-lagged panel models for each attachment figure (i.e., mother, father, peers) in a multigroup design to compare genders.Results: Better attachment to the mother led to less pronounced disturbed eating in girls across the entire age range and in boys across two time periods. In girls, more pronounced disordered eating at T3 predicted worse attachment to the mother at T4 and better attachment to the father at T1 predicted less disturbed eating at T2. In boys, disordered eating at T1 predicted better attachment to the father at T2. Concerning peer attachment, better attachment at T1 predicted disordered eating at T2, in boys only. No other significant cross-lagged effects emerged.Discussion: These findings highlight the differential and gender-specific contribution of attachment figures to the development of disordered eating in adolescence. Programs aimed at improving communication and trust in the relationship with parents might be promising in the prevention of disordered eating and the subsequent deterioration of parent-child attachment relationships.
