- In the last decades, extensive research efforts have been directed at exploring life satisfaction in old age, and the Life Satisfaction Index A scale (LSIA), developed by Neugarten et al. in the 1960s, is one of the most commonly used instruments. However, studies have focused on predicting and comparing changes in people’s life satisfaction without testing if the LSIA instrument is equally valid for different subgroups of people. The present study investigated the underlying dimensions of the LSIA in a Swedish population (n=1402) of people 60−96 years of age. The study also examined factorial invariance across age, gender, functional ability and depression during a six-year period. The results showed that while a five-factor solution of the LSIA did not exhibit an acceptable fit to the data, a three-factor solution did show a close fit. The two three-factor models that demonstrated the best fit showed invariance across gender and across time, but noninvariance across groups with different levels of reduced functional ability, depressive symptoms and age. These findings suggest that the psychometric properties of life satisfaction instruments like the LSIA need to be taken into consideration before drawing conclusions about life satisfaction when comparing older people of different ages and with different depression and function levels.

- Objectives: To investigate by use of a latent growth curve analysis framework whether athletes' individual levels and changes in hassle and uplift levels over a 10-week period could predict injury outcome in an elite junior soccer population. Design: A prospective design with repeated measurement points. Methods: Participants were 101 Swedish elite junior soccer players (67 males and 34 females). Ten sets of measures were taken on a weekly basis during which participants completed the Hassles and Uplifts Scale (HUS). Latent growth curve models were used to examine whether the level and change in psychological stress could predict the frequency of injury over the 10-week period. Results: The results show that injury occurrence was significantly associated with both the initial level of daily hassle and the change in daily hassle. High initial daily hassle levels and a smaller decrease in daily hassles were associated with injury occurrence. Moreover, injury occurrence was significantly associated with a greater decrease in daily uplift. Conclusions: The findings highlight the importance of focusing on state variables using prospective designs and appropriate analysis of within-person change to detect complex and dynamic associations across time in injury-prediction research.

- Regular physical exercise/activity has been shown repeatedly to promote positive benefits in cognitive, emotional and motor domains concomitant with reductions in distress and negative affect. It exerts a preventative role in anxiety and depressive states and facilitates psychological well-being in both adolescents and adults. Not least, several meta-analyses attest to improvements brought about by exercise. In the present treatise, the beneficial effects of exercise upon cognitive, executive function and working memory, emotional, self-esteem and depressed mood, motivational, anhedonia and psychomotor retardation, and somatic/physical, sleep disturbances and chronic aches and pains, categories of depression are discussed. Concurrently, the amelioration of several biomarkers associated with depressive states: hypothalamic-pituitary-adrenal (HPA) axis homeostasis, anti-neurodegenerative effects, monoamine metabolism regulation and neuroimmune functioning. The notion that physical exercise may function as "scaffolding" that buttresses available network circuits, anti-inflammatory defences and neuroreparative processes, e.g. brain-derived neurotrophic factor (BDNF), holds a certain appeal. © 2014 Bentham Science Publishers.

- Cognition plays a key role in sports performance. This meta-analytic review synthesizes research that examined the relationship between cognitive functions, skills, and sports performance. We identified literature by searching Cochrane Library, APA PsycINFO, PubMed, and Web of Science. We included studies conducted on competitive athletes, assessed cognitive prerequisites, and included performance measures related to the sport. Of the 9,433 screened records, 136 reports were included, containing 142 studies, 1,227 effect sizes, and 8,860 participants. Only 11 studies used a prospective study design. The risk of bias was assessed using the Risk of Bias Assessment Tool for Nonrandomized Studies. The multilevel meta-analysis showed a medium effect size for the overall difference in cognitive functions and skills, with higher skilled athletes scoring better than lower skilled athletes (Hedges' g = 0.59, 95% CI [0.49, 0.69]). The moderator analysis showed larger effect size for tests of cognitive decision-making skills (g = 0.77, 95% CI [0.6, 0.94]) compared to basic (g = 0.39, 95% CI [0.21, 0.56]) and higher cognitive functions (g = 0.44, 95% CI [0.26, 0.62]), as well as larger effect for sport-specific task stimuli compared to general ones. We report that higher skilled athletes perform better on cognitive function tests than lower skilled athletes. There was insufficient evidence to determine whether cognitive functions and skills can predict future sport performance. We found no evidence to support claims that tests of general cognitive functions, such as executive functioning, should be used by practitioners for talent identification or player selection. Public Significance Statement This meta-analysis indicates that testing cognitive functions or skills using sport-specific stimuli has the potential to differentiate between elite and nonelite athletes. There is, however, no evidence for the usefulness of using general, non-sport-specific cognitive function tests to predict future sport performance.

- Aims and objectives The purpose of this study was to examine, by using patient cohort data, the changes in exercise habits during a 12-month multimodal treatment period, in patients seeking specialist care for stress-related exhaustion. Background Randomised controlled trials have greatly contributed to the fact that both physicians and patients regard regular exercise participation as a highly valuable and effective treatment for mental health disorders. Nevertheless, little is known about the adherence to physical activity recommendations for patients with stress-related mental problems in a clinical setting. Knowledge about what can be achieved within the clinical context, and how current treatments can be improved, is crucial for clinicians, researchers, educators, managers and policy makers involved in nursing practice. Design Longitudinal analysis of patient cohort data. Methods The sample consisted of 169 patients (79% women; mean age = 42·7 years) who were referred to a stress clinic due to stress-related exhaustion. All patients received multimodal treatment with similar components. Two different approaches to promote exercise were used in the clinical work (general comprehensive instruction either with or without an 18-week coached exercise programme). The self-reported overall exercise level was assessed at baseline and at three, six and 12 months after the first visit. Group by time effects were examined with repeated measures analyses of variance. Results The frequency, duration and intensity of exercise increased substantially during the first three months of multimodal treatment. Although exercise levels tended to decrease thereafter, there was still a significant time effect at the 12-month follow-up showing that follow-up exercise levels were higher than at baseline. Conclusion Both general exercise instructions and coached exercise were effective in promoting exercise involvement. Relevance to clinical practice Exercise can be successfully promoted as a part of multimodal treatment in patients with stress-related exhaustion.

Konferensbidrag (refereegranskat)abstract
- Purpose: In a recent published article series in International Journal of Behavioral Nutrition and Physical Activity a marriage between Self-Determination Theory (SDT) and Motivational Interviewing (MI) was proposed. The purpose of the present paper is to describe the rationale and development of individual counseling, based on the tenets of SDT and techniques drawn from MI, used to promote exercise adherence.Methods: A review of the literature relevant to the marriage of SDT and MI was conducted, and a counseling approach based on SDT and MI progressed. Guidelines for how to support individuals basic needs in individual counseling and scripts for individual counselling sessions to promote exercise adherence was developed.Results: To support the individuals need for autonomy, competence and relatedness different techniques and approaches was proposed. The counseling technique is now being tested in a randomized control intervention (intervention group (n=50), control group (n=50)) to promote regular exercise among healthy, inactive adults.Conclusions: This paper outlines the rationale and development of individual counseling based on SDT and MI. Although a ‘complete marriage’ between SDT and MI may not be possible, an initial step towards a ‘new’ counseling approach has been made.

- The current study examines the role of social contact intensity, cognitive activity, and depressive symptoms as within- and between-person mediators for the relationships between physical activity and cognitive functioning. All three types of mediators were considered simultaneously using multilevel structural equations modeling with longitudinal data. The sample consisted of 470 adults ranging from 79.37 to 97.92 years of age (M = 83.4; SD = 3.2) at the first occasion. Between-person differences in cognitive activity mediated the relationship between physical activity and cognitive functioning, such that individuals who participated in more physical activities, on average, engaged in more cognitive activities and, in turn, showed better cognitive functioning. Mediation of between-person associations between physical activity and memory through social contact intensity was also significant. At the within-person level, only cognitive activity mediated the relationship between physical activity and change in cognition; however, the indirect effect was small. Depressive symptomatology was not found to significantly mediate within- or between-person effects on cognitive change. Our findings highlight the implications of physical activity participation for the prevention of cognitive decline and the importance of meditational processes at the between-person level. Physical activity can provide older adults with an avenue to make new friendships and engage in more cognitive activities which, in turn, attenuates cognitive decline.

Tidskriftsartikel (refereegranskat)abstract
- Background Based on the Self-determination theory process model, this study aimed to explore relationships between the latent constructs of psychological need satisfaction, autonomous motivation and exercise behaviour; the mediational role of autonomous motivation in the association of psychological need satisfaction with exercise behaviour; as well as gender and age differences in the aforementioned associations. Methods Adult active members of an Internet-based exercise program (n = 1091) between 18 and 78 years of age completed a test battery on motivational aspects based on Self-determination theory. The Basic Psychological Needs in Exercise Scale and the Behavioural Regulation in Exercise Questionnaire-2 were used to measure need satisfaction and type of motivation and the Leisure Time Exercise Questionnaire to measure self-reported exercise. Results Need satisfaction predicted autonomous motivation, which in turn predicted exercise, especially for women. Autonomous motivation was found to mediate the association between need satisfaction and exercise. Age and gender moderated several of the paths in the model linking need satisfaction with motivation and exercise. Conclusion The results demonstrated gender and age differences in the proposed sequential mechanisms between autonomous motivation and exercise in the process model. This study thus highlights a potential value in considering moderating factors and the need to further examine the underlying mechanisms between needs, autonomous motivation, and exercise behaviour.
