In this exploratory research study, the unemployment experience of people involved in the fishery and living in the outports of Newfoundland and Labrador was explored. Fifty‐three critical incident interviews were conducted by community outreach workers. These interviews yielded important information about the factors that facilitated or hindered the unemployment experience. In interpreting the results, both the general literature on unemployment as well as the special contextual aspects of the situation were explored.  相似文献

Concepts from the health belief, transtheoretical, and dual process models were used to examine how siblings of individuals diagnosed with colorectal cancer (CRC) before age 56 made decisions about CRC screening. Siblings (N = 504) were assessed for CRC screening practices and intentions, pros, cons, processes-of-change, perceived risk of CRC, perceived severity of CRC, preventability of CRC, cancer-related distress, and sibling relationship closeness. Physician and family recommendation and knowledge were also assessed. Fifty-seven percent of participants (n = 287) were compliant with CRC screening. Logistic regression indicated that perceived pros and cons, perceived risk, commitment to screening, health care avoidance, and sibling closeness were associated with screening compliance. Physician and family recommendation were also strong correlates. A similar set of factors was associated with stage of adoption of CRC screening.  相似文献

The present study examined the efficacy of a behavioral intervention designed to increase adherence to fluid-intake restrictions among hemodialysis patients. Twenty intervention-group patients were compared with 20 matched control patients on an indicator of fluid-intake adherence at 3 time points. The Group x Time interaction was significant, indicating that patients in the 2 groups exhibited a differential pattern of change in fluid-intake adherence across the follow-up period. The intervention and control groups did not differ significantly in terms of adherence at the initial postintervention period but did differ at the 8-week follow-up. The observed group differences were, in part, due to a trend toward increasingly better adherence in the intervention group and poorer adherence in the control group across the follow-up period.  相似文献

The psychometrics of many self-report measures of anxiety and depression have been established for patients with anxiety disorders, but little is known about use of these measures in patients with psychotic disorders. This study examined psychometrics of commonly used self-report measures. Self-report measures and interviewer ratings were collected on 33 outpatients diagnosed with schizophrenia disorders. A sample of 46 patients with anxiety disorders completed the same self-report measures. Internal consistency was high for the self-report measures in both samples. Test-retest reliability was moderate to high. Scores on self-report measures were correlated with interviewer ratings and with scores on other self-report measures of similar constructs, supporting the convergent validity of the measures. Reliable and valid information about anxiety and depression can be obtained through administering the self-report measures to outpatients diagnosed with psychotic disorders. There was more overlap among measures than was expected, possibly because of poor discriminant validity. One explanation of this may be that anxiety constructs overlap more in patients with schizophrenia or related disorders than in non-psychotic populations.  相似文献

A server-side program for animation experiments is presented. The program is capable of delivering an experiment composed of discrete animation sequences in various file formats, collecting a discrete or continuous response from the observer, evaluating the appropriateness of the response, and ensuring that the user is not proceeding at an unreasonable rate. Most parameters of the program are controllable by experimenter-edited text files or simple switches in the program code, thereby minimizing the need for programming to create new experiments. A simple demonstration experiment is discussed and is freely available.  相似文献

Abstract. This brief meditation on teaching was shared at a gathering of mid‐career theological school teachers for a retreat in Scottsdale, Arizona. It draws upon the author's familiarity with the desert to provide a metaphoric exploration of the “desiccation and delight” that surprises us repeatedly in our classrooms and instructs us in humility and hope.  相似文献

Within this paper we examine the nature and characteristics of the concept of unconditional positive regard (UPR) and discuss how an experience of conscious identification (CI) within a person-centred counsellor may affect its levels and manifestations. Initially, theoretical aspects of UPR are examined, with reference to potential threats or benefits to UPR when a counsellor experiences CI. Following on from this, we discuss how this may affect practice, drawing upon data generated from a 4-year research study, which defined and examined the process of CI.  相似文献
