Previous research has demonstrated that wilderness therapy is effective, yet very few studies have attempted to discern quantitative factors responsible for change that occur during wilderness therapy. This study aimed to tease apart specific factors that impact client progress and outcome. A sample of 189 adolescent clients in a wilderness therapy program completed the Youth Outcome Questionnaire Self-Report, the University of Rhode Island Change Assessment (URICA), and the Adolescent Relapse Coping Questionnaire (ARCQ) at pre-treatment, post-treatment, and follow-up intervals. Analysis of the complete data sets of 41 adolescents indicated that client Y-OQ scores improved significantly at post and follow-up assessments. URICA scores were not significantly related to such changes, while the ARCQ subscale of abstinence-focused coping strategies accounted for a significant proportion of the variance in Y-OQ change. These results indicate that clients in wilderness therapy do not necessarily need to want to change in order to do so. Furthermore, helping adolescents in wilderness therapy settings gain abstinence-focused coping strategies may be the most effective tool to improve treatment outcomes.  相似文献

Given the increasing prominence of both bystander-based approaches to gender-based violence (GBV) prevention and of proactively engaging men and boys to join efforts to end GBV, understanding the factors that support men’s antiviolence bystander behavior is important. This study examined correlates of willingness to engage in violence preventative bystander behavior in a global sample of 299 adult men engaged in GBV prevention events or work. Participants came from over 50 countries and provided data via an online, anonymous survey available in English, Spanish, and French. Path analysis was used to model participants’ willingness to engage in a variety of violence-preventative behaviors in the future, with variable selection guided by the Theory of Planned Behavior (TPB) and by research implicating gender-related attitudes in bystander willingness and behavior. Findings suggest that bystander willingness was supported by past bystander behavior, self-efficacy to engage in bystander behavior, positive beliefs about the contributions of antiviolence involvement, and by an awareness of male privilege. Social network support for GBV prevention work, and support for gender equity were not significant correlates of bystander willingness in the full path model. These findings held across participants from the Global North and Global South, suggesting that self-efficacy, an awareness of male privilege, and positive attitudes toward antiviolence work are factors which may support men’s violence preventative actions across broad regional contexts.  相似文献

What is exemplification? A proposition that attributes a property to an object is true if the object exemplifies the property. But according to the correspondence theory, a proposition is true if the corresponding fact exists. So if the correspondence theory is correct, an exemplification of a temporal property by an object is simply the concrete circumstance of the object’s having the property. But since not all properties are temporal, not all exemplifications are circumstances, and we need to recognise timeless as well as temporal facts. This distinction allows us to solve the problem of converse relations, and to give an account of the logically complex facts which deduction allows us to know.  相似文献

A large body of research suggests that child maltreatment (CM) is associated with adolescent suicidal ideation and attempts. These studies, however, have not been critically examined and summarized in a manner that allows us to draw firm conclusions and make recommendations for future research and clinical work in this area. In this review, we evaluated all of the research literature to date examining the relationship between CM and adolescent suicidal ideation and attempts. Results generally suggest that childhood sexual abuse, physical abuse, emotional abuse, and neglect are associated with adolescent suicidal ideation and attempts across community, clinical, and high-risk samples, using cross-sectional and longitudinal research designs. In most studies, these associations remain significant when controlling for covariates such as youth demographics, mental health, family, and peer-related variables. When different forms of CM are examined in the same multivariate analysis, most research suggests that each form of CM maintains an independent association with adolescent suicidal ideation and suicide attempts. However, a subset of studies yielded evidence to suggest that sexual abuse and emotional abuse may be relatively more important in explaining suicidal behavior than physical abuse or neglect. Research also suggests an additive effect—each form of CM contributes unique variance to adolescent suicide attempts. We discuss the current limitations of this literature and offer recommendations for future research. We conclude with an overview of the clinical implications of this research, including careful, detailed screening of CM history, past suicidal behavior, and current suicidal ideation, as well as the need for integrated treatment approaches that effectively address both CM and adolescent suicidal ideation and suicide attempts.  相似文献

The boundary paradigm (Rayner, 1975) with a novel preview manipulation was used to examine the extent of parafoveal processing of words to the right of fixation. Words n+1 and n+2 had either correct or incorrect previews prior to fixation (prior to crossing the boundary location). In addition, the manipulation utilized either a high or low frequency word in word n+1 location on the assumption that it would be more likely that n+2 preview effects could be obtained when word n+1 was high frequency. The primary findings were that there was no evidence for a preview benefit for word n+2 and no evidence for parafoveal-on-foveal effects when word n+1 is at least four letters long. We discuss implications for models of eye-movement control in reading.  相似文献

The effect of state anxiety on analogical reasoning was investigated by examining qualitative differences in mapping performance between anxious and non-anxious individuals reasoning about pictorial analogies. The working-memory restriction theory of anxiety, coupled with theories of analogy that link complexity of mapping with working-memory capacity, predicts that high anxiety will impair the ability to find correspondences based on relations between multiple objects relative to correspondences based on overlap of attributes between individual objects. Anxiety was induced in one condition by a stressful speeded subtraction task administered prior to the analogy task. Anxious participants produced fewer relational responses and more attribute responses than did non-anxious participants, both in the absence of explicit instructions to find relational mappings (Experiment 1) and after receiving such instructions (Experiment 2). The findings support the postulated links among anxiety, working memory, and the ability to perform complex analogical mapping.  相似文献

ABSTRACT

Humans are cognitive misers because their basic tendency is to default to processing mechanisms of low computational expense. Such a tendency leads to suboptimal outcomes in certain types of hostile environments. The theoretical inferences made from correct and incorrect responding on heuristics and biases tasks have been overly simplified, however. The framework developed here traces the complexities inherent in these tasks by identifying five processing states that are possible in most heuristics and biases tasks. The framework also identifies three possible processing defects: inadequately learned mindware; failure to detect the necessity of overriding the miserly response; and failure to sustain the override process once initiated. An important insight gained from using the framework is that degree of mindware instantiation is strongly related to the probability of successful detection and override. Thus, errors on such tasks cannot be unambiguously attributed to miserly processing – and correct responses are not necessarily the result of computationally expensive cognition.  相似文献
