Physical self-concept and self-esteem mediate cross-sectional relations of physical activity and sport participation with depression symptoms among adolescent girls.

The authors tested whether physical self-concept and self-esteem would mediate cross-sectional relations of physical activity and sport participation with depression symptoms among 1,250 girls in 12th grade. There was a strong positive relation between global physical self-concept and self-esteem and a moderate inverse relation between self-esteem and depression symptoms. Physical activity and sport participation each had an indirect, positive relation with global physical self-concept that was independent of objective measures of cardiorespiratory fitness and body fatness. These correlational findings provide initial evidence suggesting that physical activity and sport participation might reduce depression risk among adolescent girls by unique, positive influences on physical self-concept that operate independently of fitness, body mass index, and perceptions of sports competence, body fat, and appearance.     

Motivation for Dental Home Care: Testing a Self‐Determination Theory Model1

The present research developed the Self‐Regulation for Dental Home Care Questionnaire (SRDHCQ), based on self‐determination theory (SDT; Deci & Ryan, 2000 ), and used it in an SDT process model of dental health behaviors and self‐rated oral health. In this model, patients' perceptions of autonomy‐supportive (relative to controlling) dental professionals were expected to positively predict patients' psychological needs satisfaction in treatment. Needs satisfaction was expected to be positively related to autonomous motivation for dental home care and perceived dental competence, which were expected to be positively associated with self‐rated oral health and dental health behaviors. Confirmatory factor analysis of the 5‐factor SRDHCQ model fit the data very well, and a structural equation model supported the hypothesized process model.     

Word fluency performance and strategies in children with cochlear implants: age‐dependent effects?

Löfkvist, U., Almkvist, O., Lyxell, B. & Tallberg, I.‐M. (2012). Word fluency performance and strategies in children with cochlear implants: age‐dependent effects? Scandinavian Journal of Psychology 53, 467–474. Word fluency was examined in 73 Swedish children aged 6–9 years divided into two age groups, 6–7 and 8–9 years; 34 deaf children with cochlear implants (CI) (15 girls/19 boys) and 39 age‐matched children with normal hearing (NH) (20 girls/19 boys). One purpose was to compare the ability to retrieve words in two different word fluency tasks; one phonemically based (FAS letter fluency) and one semantically based (animal fluency). A second purpose was to examine retrieval strategies in the two tasks by conducting an analysis of clustering and switching of word sequences. In general we found that age was an important factor for word fluency ability, in both the CI and the NH groups. It was also demonstrated that children with CI aged 8–9 years retrieved significantly fewer words and used less efficient strategies in the retrieval process, especially on the phonemically based task compared to children with NH of the same ages, whereas children 6–7 years performed similarly in both groups regarding number of retrieved words and use of strategies. The results are discussed with respect to factors such as age differences in performance for children with CI, especially for the phonemically based task.     

Cognitive vulnerability to depression: a comparison of the weakest link, keystone and additive models

Multiple theories of cognitive vulnerability to depression have been proposed, each focusing on different aspects of negative cognition and utilising different measures of risk. Various methods of integrating such multiple indices of risk have been examined in the literature, and each demonstrates some promise. Yet little is known about the interrelations among these methods, or their incremental validity in predicting changes in depression. The present study compared three integrative models of cognitive vulnerability: the additive, weakest link, and keystone models. Support was found for each model as predictive of depression over time, but only the weakest link model demonstrated incremental utility in predicting changes in depression over the other models. We also explore the correlation between these models and each model's unique contribution to predicting onset of depressive symptoms.     

Attachment and well-being: The mediating effects of psychological needs satisfaction within the coach–athlete and parent–athlete relational contexts

ObjectivesGrounded in attachment theory and self-determination theory, this study aimed to examine whether basic needs satisfaction is a mechanism by which athletes' insecure attachment styles are associated with levels of well-being.MethodAthletes (N = 430) from a range of sports and competition levels completed a multi-section questionnaire to assess the main variables of the study.ResultsBootstrap mediation analysis revealed that athletes' perceptions of satisfaction of basic psychological needs generally mediated the association between their attachment styles and well-being. Moreover, the indirect effect of athletes' experience of the satisfaction of basic needs on well-being was greater within the parental relational context than within the coaching relational context.ConclusionsOverall, the findings from the study highlight that the integration of attachment and self-determination theories can promote understanding of relational process in sport.

Hemispheric asymmetry in the processing of negative and positive words: A divided field study

Research on the lateralisation of brain functions for emotion has yielded different results as a function of whether it is the experience, expression, or perceptual processing of emotion that is examined. Further, for the perception of emotion there appear to be differences between the processing of verbal and nonverbal stimuli. The present research examined the hemispheric asymmetry in the processing of verbal stimuli varying in emotional valence. Participants performed a lexical decision task for words varying in affective valence (but equated in terms of arousal) that were presented briefly to the right or left visual field. Participants were significantly faster at recognising positive words presented to the right visual field/left hemisphere. This pattern did not occur for negative words (and was reversed for high arousal negative words). These results suggest that the processing of verbal stimuli varying in emotional valence tends to parallel hemispheric asymmetry in the experience of emotion.     

Testing the cognitive catalyst model of depression: does rumination amplify the impact of cognitive diatheses in response to stress?

Recent studies have found that rumination functions as a catalyst of cognitive vulnerability to depression. Specifically, these studies have reported synergistic effects between rumination and negative cognitive content (beliefs and attitudes), such that rumination amplifies the association between negative cognitive content and depression (Ciesla & Roberts, 2002, 2007; Robinson & Alloy, 2003). The current study extended this work by testing whether cognitive vulnerability involving the combination of negative cognitive content and rumination increases the impact of stress on the course of depressive symptoms. One hundred ninety-one college students with elevated depressive symptoms participated in a two-wave longitudinal study. Results indicate that the maintenance of depressive symptoms was predicted by the three-way interaction of negative cognitive content, rumination, and stressful life events. More specifically, students who endorsed both maladaptive cognitive content and a tendency to ruminate were particularly vulnerable to the deleterious impact of life stress.
