The authors suggest that when counselors have a rich understanding of pretreatment changes, they are better able to assist clients in capitalizing on such changes. The current study examined client perceptions of pretreatment changes. Thirty‐six clients completed Q‐sorts pertaining to pretreatment changes they experienced. Four factors pertaining to client perceptions of pretreatment change emerged from the study: problem legitimacy, spiritual resources, ambivalence, and hope. Clinical implications for working with the different pretreatment changes that emerged from this study are discussed.  相似文献

As the drive for muscularity is an important construct for researchers involved in understanding men's body image, having reliable and valid measures of the construct is essential. This study assessed the Drive for Muscularity Scale (DMS) in a community-based sample of 594 Scottish men participating in an organized running event. Exploratory factor analysis revealed two subscales (Muscularity-oriented body image and Muscularity behavior) as well as a higher-order factor. Both subscales and the total score had acceptable levels of internal consistency, test–retest reliability, and construct validity. These findings provide support for the DMS as a measure of the drive for muscularity in men. It is recommended that, in future, careful consideration is given to the distinction between muscularity attitudes and behavior.  相似文献

This essay examines the fundamental fact of specificity in behaviors both outside and inside the testing room. Two tests of the same construct typically have a moderate to low correlation between them, the level of relationship depending on whether the mode, the situation, the task, and the stimuli for one test are similar to or different from those for the other. The great majority of psychological tests have considerable specificity. Their scores tend to correlate far less than perfectly with other tests of the same variable. Even when an ability is defined within a model such as Guilford's Structure-of-Intellect, each test of that ability will usually have some specific determinants not shared by other tests of that aspect of intelligence. Moreover, such a test is likely to correlate almost as well with tests of other similar abilities as with tests of its particular one.  相似文献

A geometric approach is introduced to explain phenomena that can arise with Luce's choice axiom; e.g., differences occur when determining the likelihood of a ranking by starting with the “best-first,” or “worst-first” alternative. As shown, the problem is caused by the way we compute pairwise probabilities: it forces “best-first” and “worst-first” computations to use different information from a profile. Thus agreement holds only should the different information agree: this happens only with complete indifference. An alternative “best-first” and “worst-first” comparison, which always holds, is developed. Ways to increase the applicability of the choice axiom are introduced; e.g., profiles admitted by Luce's formulation for ten alternatives have nine degrees of freedom; the approach described here allows millions of degrees of freedom. New ways to compute probabilities, which combine “best-first” and “worst-first” computations, are given: their properties are identified with a profile decomposition. A new way to compute pairwise probabilities, which eliminates all profile restrictions and problems associated with the choice axiom, is introduced; e.g., “best-first” and “worst-first” computations now agree. Three and four alternatives are emphasized for reasons of exposition, but most results extend to any number of alternatives.  相似文献

Abstract. Recent discourse on emergence within the natural sciences offers a superior alternative to traditional notions of transcendence. Emergence is a term of common parlance in the natural sciences. It designates moments when various systems develop an internal dynamic that generates an entirely new level of complexity, a qualitatively different mode of existence that cannot simply be reduced to its constituent parts. To the natural scientist, emergence is an expression of transcendence without reference to final causality or central organizing principle. Autopoietic emergence is more congruent with contemporary understandings of the universe than the traditional anthropomorphizing concept of teleological design. In this article I offer both an interpretation of emergence as a new category for the interpretation of divinity and an explanation for traditional anthropomorphism rooted in contemporary cognitive sciences.  相似文献

We introduce the concept of “neurobiological foundation” of Rorschach interpretations as an extension of the concept of behavioral representation as a foundation for interpretation of R‐PAS variables. Here, we propose that if there is a parallelism between the mental, verbal and perceptual behaviors occurring within the microcosm of the Rorschach task and those occurring in the external environment [behavioral foundation], then the same brain regions engaged by the test‐taker when producing of a given code, should be engaged also when reproducing, in the external environment, the same psychological processes underlying that specific Rorschach code [neurobiological foundation]. To investigate this concept, we used archival, fMRI data and tested whether producing Oral Dependency Language (ODL) responses would associate with increased activation in brain regions associated with dependency‐related, psychological processes. Results from a sample of 21 non‐clinical volunteers partially confirmed our hypothesis, providing some support to the neurobiological foundation of the ODL code.  相似文献

Individuals responsible for carrying out research within their diverse communities experience a critical need for research ethics training materials that align with community values. To improve the capacity to meet local human subject protections, we created the research Ethics Training for Health in Indigenous Communities (rETHICS), a training curriculum aligned within American Indian and Alaska Native (AI/AN) context, culture, and community‐level ethical values and principles. Beginning with the Belmont Report and the Common Rule that defines research with human subjects (46 CFR 45), the authors convened three different expert panels (N = 37) to identify Indigenous research values and principles common across tribal communities. The resulting culturally grounded curriculum was then tested with 48 AI/AN individuals, 39 who also had recorded debriefing interviews. Using a thematic analysis, we coded the qualitative feedback from the expert panel discussions and the participant debriefings to assess content validity. Participants identified five foundational constructs needed to ensure cultural‐grounding of the AI/AN‐specific research training curriculum. These included ensuring that the module was: (a) framed within an AI/AN historical context; (b) reflected Indigenous moral values; (c) specifically linked AI/AN cultural considerations to ethical procedures; (d) contributed to a growing Indigenous ethics; and (e) provided Indigenous‐based ethics tools for decision making. Using community‐based consultation and feedback from participants led to a culturally grounded training curriculum that teaches research ethical principles and procedures for conducting research with AI/ANs. The curriculum is available for free and the community‐based process used can be adapted for other cultural groups.  相似文献

Five-Factor Model (FFM) personality disorder (PD) counts have demonstrated significant convergent and discriminant validity with DSM-IV PD symptoms. However, these FFM PD counts are of limited clinical use without normative data because it is difficult to determine what a specific score means with regard to the relative level of elevation. The current study presents data from three large normative samples that can be used as norms for the FFM PD counts in the respective countries: United States (N = 1,000), France (N = 801), and Belgium-Netherlands (N = 549). The present study also examines the performance, with regard to diagnostic efficiency, of statistically-defined cut-offs at 1.5 standard deviations above the mean (T > or = 65) versus previously identified cut-offs using receiver-operator characteristics (ROC) analyses. These cut-offs are tested in three clinical samples-one from each of the aforementioned countries. In general, the T > or = 65 cut-offs performed similarly to those identified using ROC analyses and manifested properties relevant to a screening instrument. These normative data allow FFM data to be used in a flexible and comprehensive manner, which may include scoring this type of personality data in order to screen for DSM-IV PD constructs.  相似文献

We surveyed 2,125 men and 3,735 women (N = 5,860) across the USA to test hypothesized relationships regarding women’s and men’s use of justice and care orientations when they confront crisis events with moral implications. Consistent with previous research, we found that women were more likely than men to adopt a care orientation. Contrary to expectations, however, women also adopted a justice response to a greater degree than did men. We found that, in response to a crisis, women, unlike men, were more likely to believe they would connect with others and take action. Implications for explaining inconsistencies in prior research findings on the justice and care orientations, and for conceptualizing these important constructs in a new way, are discussed.  相似文献
