Research examined the effects of a supervised physical activity program on potential psychosocial mediators and determined whether changes in these psychosocial variables predicted changes in physical activity and fitness. Sedentary adolescent females were assigned to an intervention (n?=?79) or comparison (n?=?67) group. Cardiovascular fitness (cycle ergometer), physical activity (3-Day Physical Activity Recall), and psychosocial variables related to physical activity (i.e., self-efficacy, perceived barriers, social support, enjoyment) were assessed at three time points over the 9-month study. An intention-to-treat analysis showed that the intervention did not impact any of the psychosocial variables, with the exception of perceived barriers, which increased in the intervention group. Longitudinal analyses showed that improvements in fitness were associated with positive changes in global self-efficacy and exercise enjoyment. Psychosocial variables did not mediate the program's effects on fitness or activity. However, individual level changes in psychosocial variables were related to changes in cardiovascular fitness. 相似文献

This research examined whether developmental changes occur in young children's abilities to learn transitive information. Children 4 years 6 months to 5 years 6 months and 6 to 7 years were asked to learn a series, A > B > C, or a nonseries, A > B, C > D. Younger children took longer to learn the series than the nonseries. Children learning the series correctly answered the inference question, but could not distinguish between situations in which it was possible or impossible to make inferences. The results suggest that there are developmental changes in transitivity abilities and that transitivity is a concept that emerges gradually. 相似文献

Aims: The purpose of this study was to identify what patients with primary cancers found helpful in therapy. Method: In‐depth qualitative interviews were conducted with eight patients who had completed a course of psychological therapy within an NHS psychology service for cancer patients. Data were analysed using thematic analysis. Results: The participants identified a range of helpful processes in therapy: talking and expressing their feelings to someone outside of the family; forming a relationship with their therapist; normalisation through the therapists' expert knowledge; problem‐solving and CBT. Limitations: As with all qualitative studies, the small sample and size and dependence on participant recall limits generalisability of the findings. Implications: The findings of this study are consistent with a pluralistic perspective: that multiple therapeutic processes ‐ aligned to a range of different orientations ‐ can be of value to patients with primary cancers. This supports the provision of a range of therapeutic interventions and strategies for this patient group. 相似文献

The current study examined psychosocial predictors of change in intercourse frequency and number of sexual partners among youth within a socio-ecological framework and assessed whether these determinants vary by stage of adolescent development. Longitudinal data were derived from a large, community study of adolescent risky behavior among predominantly high-risk, African American youth. Significant predictors of intercourse frequency for early adolescents included age, gender, self-worth, and familial factors; for older youth, age, gender, self-worth, curfews, and sense of community exerted significant effects. Among early adolescents, age, gender, self-worth, familial factors, and sense of community predicted change in the number of sexual partners in the previous year, while age, gender, self-worth, parental knowledge, curfews, and sense of community were predictive of change in the number of sexual partners in the previous year among older youth. Study implications and future directions are discussed. 相似文献

Is tragedy, as Nietzsche declared, dead? In recent years many philosophers have reconsidered tragedy's relation to philosophy. While tragedy is deemed to contain important lessons for philosophy, there is a consensus that it remains a thing of the past. This article calls this consensus into question, arguing that it reifies tragedy, keeping tragedy at arm's length. With the interest of identifying the necessity of tragedy to philosophy, it draws from Quentin Skinner to put forward an alternative approach to genre as living form. This approach alters our understanding of the philosopher at the heart of philosophy's dialogue with tragedy, Immanuel Kant. Moreover, it shows that tragedy is closer to contemporary philosophy than we might think. 相似文献
