The authors measured perceptions of safety climate, motivation, and behavior at 2 time points and linked them to prior and subsequent levels of accidents over a 5-year period. A series of analyses examined the effects of top-down and bottom-up processes operating simultaneously over time. In terms of top-down effects, average levels of safety climate within groups at 1 point in time predicted subsequent changes in individual safety motivation. Individual safety motivation, in turn, was associated with subsequent changes in self-reported safety behavior. In terms of bottom-up effects, improvements in the average level of safety behavior within groups were associated with a subsequent reduction in accidents at the group level. The results contribute to an understanding of the factors influencing workplace safety and the levels and lags at which these effects operate.  相似文献

Individual Beck Depression Inventory (BDI) time courses of 38 clients receiving cognitive therapy (CT) and a modified form of CT were studied in order to investigate temporal changes during CT for depression. The primary aim was to determine if alternative methods of defining and computing gains occurring early in CT would alter the conclusions drawn in the current literature. Three types of gains were studied: sudden gains (previously studied sudden, substantial, and stable improvements in depression during 1 between-session interval after Session 2), first-session gains (occurring after first sessions), and pretreatment gains (occurring after pretreatment assessments). Positive outcomes were predicted by first-session gains and by sudden gains occurring in the first half of treatment, highlighting the importance of early change in CT for depression.  相似文献

The current study investigated a behavior-analytic treatment, functional analytic psychotherapy (FAP), for outpatient depression utilizing two single-subject A/A+B designs. The baseline condition was cognitive behavioral therapy. Results demonstrated treatment success in 1 client after the addition of FAP and treatment failure in the 2nd. This study highlights the challenges in measuring treatment progress and outcome idiographically in this population.  相似文献

Goal orientation is a multidimensional construct widely examined by social, organizational, educational, and sports psychology researchers. However, despite theoretical perspectives indicating that individuals can adopt or manifest more than one goal orientation simultaneously, researchers traditionally examine relationships between the goal orientation dimensions and outcome variables of interest independently. In contrast, this study was designed to examine whether individuals can be sorted into meaningful goal orientation profiles based on their scores on measures of learning, performance–approach, and performance–avoidance goal orientation, and the relationships between the resulting profiles and various dispositional and motivational variables. Our results indicated that a 4-profile solution best fit our data and that the 4 profiles differed uniquely across our dependent variables.  相似文献

Go/no-go tasks seem to provide a simple marker of inhibitory development in young children. Children are told to respond to one stimulus on go trials but to make no response to another stimulus on no-go trials; responding on no-go trials is assumed to reflect a failure to inhibit the go response. However, there is evidence to suggest that a type of go/no-go task, which we call the "button-press" task, does not require inhibition. We investigated the conditions under which young children (M=3 years 6 months, N=120) experience inhibitory difficulty with this type of task. The data suggest that the speed of stimulus presentation is crucial and that other studies using this type of task have presented the stimuli too briefly. The importance of establishing the inhibitory credentials of a task before it is used as a marker of inhibitory control is emphasized.  相似文献

The study investigated relationships between game location, performers' experience, and mood states. 31 experienced collegiate soccer players completed the Brunel Mood Scale to assess anger, calmness, confusion, depression, fatigue, happiness, tension, and vigor before eight competitive games (four home and four away). Participants were categorized into Experienced and Less Experienced groups, based on the level of performance at which they played. Repeated-measures multivariate analyses of variance compared mean mood scores across location and experience, and follow-up univariate analyses suggested the increase in mood scores on Tension and decrease in scores on Calmness, Happiness, and Vigor between playing away and at home were significantly greater for Less experienced soccer players than Experienced players. Implications of these findings for the applied practitioner are discussed.  相似文献

Authors have repeatedly argued that a nearly exclusive focus on the dominant form of masculinity limits our knowledge of masculinity. Qualitative masculinities researchers have revealed multiple masculine forms, but quantitative researchers have not yet assessed them. This study adopted a social identity approach to examine endorsement of ten typically male images (Average Joe, Businessman, Family Man, Jock, Nerd, Player, Rebel, Sensitive New-Age Guy, Stud, Tough Guy) and their connections to gender norms and traits. Data from 340 male and 348 female adults revealed that identification with each image was related to a particular pattern of norm conformity and trait endorsement. Patterns varied by sex. Findings suggested that distinctions across images may be assessed quantitatively. Implications for quantitative research on masculinities were discussed.  相似文献
