BackgroundExercise interventions are efficacious in reducing disorder-specific symptoms in various mental disorders. However, little is known about long-term transdiagnostic efficacy of exercise across heterogenous mental disorders and the potential mechanisms underlying treatment effects.MethodsPhysically inactive outpatients, with depressive disorders, anxiety disorders, insomnia or attention deficit hyperactivity disorder were randomized to a standardized 12-week exercise intervention, combining moderate exercise with behavior change techniques (BCTs) (n = 38), or a passive control group (n = 36). Primary outcome was global symptom severity (Symptom Checklist-90, SCL-90-R) and secondary outcomes were self-reported exercise (Physical Activity, Exercise, and Sport Questionnaire), exercise-specific affect regulation (Physical Activity-related Health Competence Questionnaire) and depression (SCL-90-R) assessed at baseline (T1), post-treatment (T2) and one year after post-treatment (T3). Intention-to-treat analyses were conducted using linear mixed models and structural equations modeling.ResultsFrom T1 to T3, the intervention group significantly improved on global symptom severity (d = −0.43, p = .031), depression among a depressed subsample (d = −0.62, p = .014), exercise (d = 0.45, p = .011) and exercise-specific affect regulation (d = 0.44, p = .028) relative to the control group. The intervention group was more likely to reveal clinically significant changes from T1 to T3 (p = .033). Increases in exercise-specific affect regulation mediated intervention effects on global symptom severity (ß = −0.28, p = .037) and clinically significant changes (ß = −0.24, p = .042).ConclusionsThe exercise intervention showed long-term efficacy among a diagnostically heterogeneous outpatient sample and led to long-lasting exercise behavior change. Long-term increases in exercise-specific affect regulation within exercise interventions seem to be essential for long-lasting symptom reduction. 相似文献

The reliable induction of lucid dreams is a challenge in lucid dream research. In a previous study by our research group we were able to induce in about 50% of the participants a lucid dream in a single sleep laboratory night by combining a wake-up-back-to-bed sleep protocol and a mnemonic technique. In the present study, we extended our previous procedure by additional presentation of an odor during sleep to reactivate memory traces about reality testing. In total 16 male participants spent a single night in the sleep lab whereas the procedure induced in two participants a lucid dream (12.5%). The induction rate stays below the success rate of our previous study and therefore odor-cueing seems not a promising technique for inducing lucid dreams. Beside the odor presentation, several other methodological changes have been made, which will be discussed and hopefully help further dream engineering to improve induction techniques. 相似文献

Referring to the work of Bruchon-Schweitzer & Ferrieux (1991) and Balicco (1999), the present study describes the recruitment practices of different types of organizations (N=327, 134 consulting companies and 193 temporary placement firms). We hypothesised that job position and recruiter characteristics (sex, age, level and type of education, status, and recruitment experience) would influence the use of selection techniques. Results revealed that choice of selection techniques is not based on a scientific evaluation of applicants. Job position seems to strongly determine use of personality assessment techniques. Further, recruiter characteristics only seem to determine choice of less valid techniques. In the discussion, a theoretical model of choices made by recruiters and some courses of action are proposed. 相似文献

In this paper we introduce Fresh Logic, a natural deduction style first-order logic extended with term-formers and quantifiers derived from the FM-sets model of names and binding in abstract syntax. Fresh Logic can be classical or intuitionistic depending on whether we include a law of excluded middle; we present a proof-normalisation procedure for the intuitionistic case and a semantics based on Kripke models in FM-sets for which it is sound and complete. 相似文献

This paper is a contribution to a more conscious use of tangible mock-ups in collaborative design processes. It describes
a design team’s use of mock-ups in a series of workshops involving potential customers and users. Focus is primarily on the
use of three-dimensional design mock-ups and how differences in these affected the dialogue. Reflective conversations were
established by using tangible mock-ups as “things-to-think with.” They served as boundary objects that spanned the gap between
the different competencies and interests of participants in design. The design mock-ups evoked different things for different
participants, whereas the challenge for the design team was to find boundaries upon which everybody could agree. The level
of details represented in a mock-up affected the communication so that a mock-up with few details evoked different issues,
whereas a very detailed mock-up evoked a smaller variation of issues resulting in a more focused communication. 相似文献

The importance of contextual information for memory organization has been advocated by memory research and ancient mnemonic techniques (e.g., method of loci), yet it remains overlooked in most current study environments. Here, German noun gender was presented to 48 participants without prior knowledge of German, either without or within a provided spatial context consisting of a simulated virtual environment that could be explored freely. The three main findings were: in addition to reduced forgetting rate, memory was significantly enhanced when acquisition had occurred with a spatial context than without, in immediate, and delayed cued recall, as well as in delayed free recall. Second, visualization ability predicted spatial context efficiency as a memory aid for cued recall. Lastly, performance of the method of loci‐based method correlated with its perceived efficiency. This is the first study to experimentally demonstrate the potential effectiveness of computer‐induced spatial context on grammar learning. 相似文献

Background: Goal-setting is recommended and widely used within diabetes self-management programmes. However, empirical evidence around its effectiveness lacks clarity. This review aims to evaluate the effectiveness of goal-setting interventions on diabetes outcomes and to determine which behaviour change techniques (BCTs) are frequently used within these interventions.Methods: A systematic search identified 14 studies, describing 12 interventions targeting diabetic-control which incorporated goal-setting as the main intervention strategy. Study characteristics, outcome measures and effect sizes of the included studies were extracted and checked by two authors. The BCT taxonomy v1 was used to identify intervention content. Meta-analyses were conducted to assess intervention effects on the primary outcome of average blood glucose levels (HbA1c) and on body-weight. Psycho-social and behavioural outcomes were summarised in narrative syntheses.Results: Significant post-intervention improvements in HbA1C were found (?.22, 95% CI, ?.40, ?.04) across studies. No other main effects were identified. The BCT ‘goal-setting (behaviour)’ was most frequently implemented and was identified in 84% of the interventions.Conclusions: Goal-setting interventions appear to be associated with reduced HbA1C levels. However, the low numbers of studies identified and the risk biases across studies suggest more research is needed to further explore goal-setting BCTs in diabetes self-management. 相似文献

Cycling has the potential to address a number of personal and societal challenges, not least with respect to health and the need for more sustainable modes of transport. However, the best way(s) to promote cycling is still unclear. In an effort to answer this question, we identified 39 interventions designed to promote cycling, with a total sample of 46,102 participants. Random effects meta-analysis estimated a small but statistically significant effect of interventions on cycling behaviour (g+ = 0.14, 95% CI [0.05, 0.23]). To identify the most effective intervention strategies, we coded the behaviour change techniques used within each of the interventions. Interventions that prompted people to self-monitor their behaviour or added objects to the environment (e.g., provided shared bikes) were more effective than those that did not use these strategies. Interventions that restructured the physical environment (e.g., built new cycle paths) were less effective than the studies that did not do this. We also identified a number of factors that moderated the effect of the interventions on outcomes; specifically, interventions that targeted a specific group, used objective measures of cycling such as accelerometers, and that were tested using independent groups designs typically yielded stronger effects. The findings should help to guide interventions to promote cycling in the future. 相似文献
