Self-determined motivation towards physical activity in adolescents treated for obesity: an observational study

Abstract: Background: Within the Self-Determination Theory (SDT) framework, the first major study aim was to investigate the SDT tenets in an obese adolescent population by examining the factor structure of the Behavioural Regulation in Exercise Questionnaire-2 (BREQ-2) and by investigating associations between physical activity (PA) and motivation in obese adolescents. The second aim was to study differences in motivation according to adolescents’ educational level, since lower educated obese adolescent are a sub-risk group for lower PA levels among the obese adolescents. The third aim was to investigate whether attending a residential obesity treatment program could lead to an increase in autonomous motivation towards PA and to see if the treatment effect on motivation was different in low versus high educated youth. Methods: For the first study aim, the sample comprised 177 obese adolescents at the start of a 10-month multidisciplinary residential obesity treatment program (BMI = 35.9 ± 6.0 kg/m 2 , 15.1 ± 1.5 years, 62% girls). A subsample of 65 adolescents (stratified by educational level) were divided into low (n = 34) versus high educated (n = 31) as part of the second and third study aim. Motivation was assessed using the BREQ-2 and PA using the Flemish Physical Activity Questionnaire. Results: Exploratory factor analysis showed sufficient validations with the original factor for 17 out of 19 BREQ-2 items. Significant positive correlations were found between PA and the composite score of relative autonomy (r = 0.31, p < 0.001), introjected (r = 0.23, p < 0.01), identified (r = 0.31, p < 0.001) and intrinsic regulation (r = 0.38, p < 0.001). Higher educated adolescents scored higher on the composite score of relative autonomy, introjected, identified and intrinsic regulation at the start of treatment (F = 3.68, p < 0.001). The composite score of relative autonomy, external, identified and intrinsic regulation significantly increased during treatment for all adolescents (F = 6.65, p < 0.001). Introjected regulation significantly increased for lower educated adolescents (F = 25.57, p < 0.001). Conclusions: The BREQ-2 can be used in an obese adolescent population. Higher levels of autonomous motivation towards PA were related to higher PA levels. Adolescents had increases in both autonomous and controlled forms of motivation during treatment. Special attention for lower educated adolescents during treatment is needed, as they have a lower autonomous motivation at the start of treatment and an increase in introjected regulation during treatment.

Emotion Regulation in Children with Emotional Problems

Abstract: The emotion regulation (ER)-specificity hypothesis assumes that a specific psychological problem is characterized by a specific maladaptive ER strategy. This hypothesis will be investigated for six child-DSM symptom clusters (Study 1) and for depressive symptoms (Study 2). We also investigated whether certain emotion regulation strategies can be detected through different forms of symptom clusters. Study 1 includes 432 school aged non-referred youngsters (60 % girls; age range between 8 and 18 years) and Study 2 includes 128 school aged non-referred youngsters (55 % girls; age range between 10 and 14 years). A self-report questionnaire, FEEL-KJ investigates a wide range of adaptive and maladaptive ER strategies. DSM symptom clusters (affective, anxiety, somatic, conduct, oppositional and ADHD problems) were measured by parent report on the Child Behaviour Checklist; depressive symptoms were measured with the Child Depression Inventory. Youngsters with emotional problems have specifically less adaptive ER strategies. The relation with maladaptive ER strategies can only be detected with self-reported depressive symptoms. ER strategies problem-oriented action and acceptance are transdiagnostically related to both internalizing and externalizing problems. For affective, somatic, conduct and ADHD problems the ER-specificity hypothesis is confirmed. Investigating ER strategies could be of clinical relevance specifically in children with affective, somatic, conduct and ADHD problems. Next, training deficits in the ER strategies Problem-oriented action and Acceptance can be considered as important in the treatment of all children with emotional problems.

Depression in Early, Middle and Late Adolescence: Differential Evidence for the Cognitive Diathesis-Stress Model

Abstract: Cognitive theory is a prominent framework to study depression in both adults and adolescents. This theory stated that dysfunctional schemas are moderators (known as diathesis) in the association of current stress and psychopathology. However, in adolescents, less evidence has been found so far to corroborate the importance of these schemas. This study aimed to investigate in a cross-sectional design the moderating role of adolescents' early maladaptive schemas (EMS) on depressive symptoms. This will be studied in relation to both important daily stressors (i.e., maternal, paternal and peer rejection) and stressful life events. METHOD Adolescents (N = 228, age 12–18 years), selected from inpatient and outpatient clinical settings and a non-referred sample, completed questionnaires and interviews measuring psychopathology, cognitive schemas, peer rejection, maternal and paternal rejection, and stressful life events. Parents completed questionnaires about their adolescent measuring psychopathology, stressful life events and peer rejection, as well as their own parental behaviour. RESULTS Correlational analyses revealed significant associations between the study variables. Evidence was found for an interaction effect between the adolescents' EMS and peer rejection in explaining depressive symptoms, but only in late adolescents. Copyright © 2012 John Wiley & Sons, Ltd. Key Practitioner Message Stress induced by maternal and, in lesser extent, paternal rejection is contributing to depressive symptoms primarily in younger and to lesser extent in older age groups. The quality of peer relationships becomes an increasingly salient source of distress as adolescence unfolds and is certainly an important mechanism affecting depression in adolescence. Maladaptive schemas only start functioning as a cognitive diathesis in late adolescence, increasing depression in response to peer-related distress. Since maladaptive schemas are not yet operating as cognitive vulnerability factors in early and middle adolescence, early interventions for depressive disorders may be more effective compared with treatment in later adolescence.

The effects of emotion regulation strategies on positive and negative affect in early adolescents

Abstract: Recent research suggests that impaired emotion regulation (ER) may play an important role in the development of youth psychopathology. However, little research has explored the effects of ER strategies on affect in early adolescents. In Study 1 (n = 76), we examined if early adolescents are able to use distraction and whether the effects of this strategy are similar to talking to one’s mother. In Study 2 (n = 184), we compared the effects of distraction, cognitive reappraisal, acceptance, and rumination. In both studies, participants received instructions on how to regulate their emotions after a standardised negative mood induction. In general, the results indicated that distraction, but also cognitive reappraisal and acceptance, had promising short-term effects on positive and negative affect in early adolescents. These findings suggest that targeting adaptive ER skills, such as distraction, acceptance, and cognitive reappraisal, may be an important strategy to prevent or treat psychological pro...

Emotion Regulation Strategies in Depressive and Anxiety Symptoms in Youth: A Meta-Analytic Review

Abstract: The role of emotion regulation in subclinical symptoms of mental disorders in adolescence is not yet well understood. This meta-analytic review examines the relationship between the habitual use of prominent adaptive emotion regulation strategies (cognitive reappraisal, problem solving, and acceptance) and maladaptive emotion regulation strategies (avoidance, suppression, and rumination) with depressive and anxiety symptoms in adolescence. Analyzing 68 effect sizes from 35 studies, we calculated overall outcomes across depressive and anxiety symptoms as well as psychopathology-specific outcomes. Age was examined as a continuous moderator via meta-regression models. The results from random effects analyses revealed that the habitual use of all emotion regulation strategies was significantly related to depressive and anxiety symptoms overall, with the adaptive emotion regulation strategies showing negative associations (i.e., less symptoms) with depressive and anxiety symptoms whereas the maladaptive emotion regulation strategies showed positive associations (i.e., more symptoms). A less frequent use of adaptive and a more frequent use of maladaptive emotion regulation strategies were associated with depressive and anxiety symptoms comparably in the respective directions. Regarding the psychopathology-specific outcomes, depressive and anxiety symptoms displayed similar patterns across emotion regulation strategies showing the strongest negative associations with acceptance, and strongest positive associations with avoidance and rumination. The findings underscore the relevance of adaptive and also maladaptive emotion regulation strategies in depressive and anxiety symptoms in youth, and highlight the need to further investigate the patterns of emotion regulation as a potential transdiagnostic factor.

Testing a Continuum Structure of Self-Determined Motivation: A Meta-Analysis

Abstract: Self-determination theory proposes a multidimensional representation of motivation comprised of several factors said to fall along a continuum of relative autonomy. The current meta-analysis examined the relationships between these motivation factors in order to demonstrate how reliably they conformed to a predictable continuum-like pattern. Based on data from 486 samples representing over 205,000 participants who completed 1 of 13 validated motivation scales, the results largely supported a continuum-like structure of motivation and indicate that self-determination is central in explaining human motivation. Further examination of heterogeneity indicated that while regulations were predictably ordered across domains and scales, the exact distance between subscales varied across samples in a way that was not explainable by a set of moderators. Results did not support the inclusion of integrated regulation or the 3 subscales of intrinsic motivation (i.e., intrinsic motivation to know, to experience stimulation, and to achieve) due to excessively high interfactor correlations and overlapping confidence intervals. Recommendations for scale refinements and the scoring of motivation are provided. (PsycINFO Database Record

Self-determination theory applied to physical education: A systematic review and meta-analysis.

Abstract: In this review we examine the evidence regarding self-determination theory within the school physical education context. We applied a multilevel structural equation modeling approach to meta-analyze data from a systematic review that identified 265 relevant studies. In line with theory, autonomous motivation was positively correlated with adaptive outcomes and negatively correlated with maladaptive outcomes. Introjected regulation was modestly correlated with both adaptive and maladaptive outcomes. External regulation and amotivation both showed negative relationships with adaptive outcomes, and positive relationship with maladaptive outcomes. Also supporting SDT, autonomy, competence, and relatedness satisfactions were strongly correlated with autonomous student motivation, and less strongly, but still positively, correlated with introjected regulation. Weak negative correlations were found between autonomy, competence, and relatedness and external regulation. Amotivation had moderate negative correlations with needs satisfaction. Findings further revealed that teachers more greatly impact classroom experiences of autonomy and competence, whereas relatedness in physical education is associated with both peer and teacher influences.
