Three separate models have been proposed to describe the factor structure of attention deficit hyperactivity disorder (ADHD) in the past 20 years. The Diagnostic and Statistical Manual of Mental Disorders-III (DSM-III, 1980) proposed 3 separate factors of inattention, hyperactivity, and impulsivity. The DSM-III-R (1987) proposed a single factor. The DSM-IV (1994) described the disorder as having 2 factors: hyperactivity/impulsivity and inattention. The following 2 studies employed confirmatory factor analysis to compare each of these models and 3 alternative models. University students completed questionnaires that assessed each of the 18 symptoms listed in the DSM-IV for ADHD. The 3-factor model fit the data significantly better than each of the other models in both studies. These findings suggest that a 3-factor model of inattention, hyperactivity, and impulsivity describes adult ADHD symptoms better than current alternatives.  相似文献

The authors of the theory of reasoned action (TRA) and its extension, the theory of planned behaviour (TPB) recommend that researchers who use these theories to investigate the determinants of a given behaviour should first conduct an elicitation study to identify the modal salient beliefs in the target population. In spite of the importance accorded to salient beliefs by the TRA/TPB, the elicitation stage has received little research attention. This paper reports a detailed analysis of beliefs about “being more physically active in the next 12 months.” A general population sample of 213 adults completed a questionnaire while attending a research centre for a series of tests. The findings showed that the beliefs that were elicited by questions designed to prompt affective outcomes (like or enjoy, dislike or hate) differed systematically from those that were elicited by the traditional questions designed to prompt instrumental out-comes (advantages and disadvantages). Whether this resulted in different final sets of modal salient beliefs was found to depend on the particular decision rule that was employed. An alternative decision rule is proposed, based on maximizing the degree of overlap between the modal set and the full set of salient beliefs generated by the sample. The index of overlap can be used to gauge the adequacy of using a modal set of a given size to represent the salient beliefs of the whole sample. In the current dataset, the optimal modal set for “advantages and disadvantages” was associated with only 26 percent overlap with the salient beliefs of the whole sample, which was judged to be insufficient. In such cases, a better strategy may be to ask participants to generate and rate their own beliefs.  相似文献

During the mid 1980s, the renowned American documentary filmmaker Fred Wiseman produced a four-part series of films that sought to record the operations of institutions in Talladega, Alabama, devoted to the care and training of people with disabilities. These films—designated as the Multi-handicapped Series—have received much less attention than Wiseman's earlier work, as if films about disability mark a drastic departure from his previous award-winning productions, such as Titicut Follies (1965) and Hospital (1970). The Multi-handicapped Series takes up general categories of disabled populations as discrete documentary topics, Deaf (1986), Blind (1986), Multi-handicapped (1986) and Adjustment & Work (1986) as opposed to a specific location as in his earlier films. As a result, the latter series of films identify social and interpersonal structures developed in the name of specific conditions. Like Foucault's research on disciplinary tactics, Wiseman's films seek out many of the segregated social spaces typically occupied by persons classified as deviant: prisons, hospitals, charity networks, sheltered workshops, resident facilities, and vocational training structures. The Multi-handicapped Series focuses on the activities of professions and practitioners in education, administration, and therapy, as well as the institutional roles designed for bodies marked as disabled. Unlike its 19th century predecessor classification, feebleminded, the latter twentieth century U.S. policy answer has been waged as a matter of dividing disabilities into a binary structure of orthopedic or cognitive categories. Such a development has left many crossover bodies in a diagnostic no-body's-land. To analyze the history of these developments, this essay recognizes the formation of today's disability category as an effect of new regimes of power; a form of domination based upon the application of particularized diagnostic pathologies that provide the basis for cordoning off bodies which fail to fit neatly within the cognitive/orthopedic binary. As documents of the social spaces that are occupied by disabled people, Wiseman's films offer a rare contemplation of institutional practices and their application to populations viewed as nonnormative.  相似文献

A behavioural method is described for the assessment of depth perception of kittens. Measurement is made of the smallest separation in depth that can be discriminated between two adjacent stimuli under both monocular and binocular viewing conditions. Normal animals can discriminate much smaller separations in depth when using two eyes than with monocular viewing, implying the presence of a cue to depth that is uniquely available with binocular viewing. The test provides a quick and reliable way of screening animals for stereopsis.  相似文献

This study investigated self-regulation and resiliency in one's search for reemployment. Although trait-based approaches are central to many resiliency conceptualizations, recent research has found that self-regulation (affective, behavioral, and cognitive) contributes to predicting resiliency-related outcomes. We hypothesized that self-regulation would incrementally predict reemployment process outcomes, specifically the job search outcomes of psychological well-being, job search self-efficacy, and job search clarity. Results indicated that, over and above resiliency traits, behavioral and cognitive self-regulation incrementally predicted well-being and job search clarity, and cognitive self-regulation incrementally predicted job search self-efficacy. Implications for theory and continued research on resiliency in reemployment are discussed.  相似文献

The high rates of suicide among older men are cause for concern, and have prompted the investigation of factors that might explain these elevated rates. The current research examined whether the gender role construct agency was associated with depression and suicidal ideation among older adults. The results, based on self‐report data from a sample of older Australian men (n = 69) and women (n = 90), indicated that depression mediated the relation between agency and suicidal ideation. In addition, for older men only, agency moderated the depression‐suicidal ideation relation. The results suggest that older adults, and particularly men, with low levels of agency should be the targets for interventions aimed at increasing levels of agency and improving mental health.  相似文献
