The purpose of this study was to examine the relations between various aspects of social support and maternal and infant outcome variables in a group of families having infants showing food refusal compared to a control group. In the case of early food refusal, the results indicated that access to emotional support and satisfaction with support were related to maternal psychosomatic health. The relationships were interpreted as showing that social support has moderating effects on negative outcomes of food refusal. 相似文献

Multiple treatment interventions including instructions, modelling, timeout, avoidance of repetition, and reinforcement were successful in establishing factual answers to personal background questions in a withdrawn and socially unresponsive chronic schizophrenic. The subject had previously persisted in giving only delusional responses to these questions. A multiple-baseline design across verbal replies to personal background questions demonstrated that the changes in behavior were brought about by the treatment interventions. During baseline, the subject was reinforced for any response to four questions. The experimental interventions were then introduced for the first question and moved sequentially to an additional question when the subject's responses reached the criterion of at least 80% correct for two consecutive sessions. Introduction of the experimental interventions produced an increase from a baseline level of zero to at least 80% correct for each question. The use of the token reinforcement procedure was faded out after the subject was able to answer all four questions correctly at least 80% of the time for two consecutive sessions. Fading of the token reinforcement procedure was accomplished by using increasingly intermittent schedules of token reinforcement during the last seven sessions. In the final session, no tokens were used to reinforce the subject's responding. Nine-, ten-, and 12-month followup interviews were conducted to evaluate the maintenance of treatment gains. Maintenance was found to be complete at the nine- and 10-month followups, but at the 12-month followup interview, the subject answered one question incorrectly. This study replicates an investigation previously reported in this journal. 相似文献

This study was conducted to develop a comprehensive Multidimensional Locus of Pain Control questionnaire (MLPC) and to examine how locus of pain control is related to pain appraisals, pain coping strategies, and adjustment to chronic pain. Subjects were 170 chronic headache patients. By means of factor analysis, four subscales were derived: an Internal, a Chance, a Physician, and a Medication locus of pain control orientation scale. The reliability and validity of the subscales appeared to be satisfactory. The results of the present study indicate that the locus of pain control orientation is significantly related to pain appraisals such as perceived pain control and catastrophizing and, to a lesser degree, to coping strategies as measured by the Coping Strategies Questionnaire (CSQ). However, almost no relationship was observed between locus of pain control and adjustment to pain. Further research with the MLPC in different chronic pain populations is warranted in order to investigate whether the results found in this study can be generalized to chronic pain patients in general. 相似文献

This study reports the results of one effort to help supermarket shoppers alter food purchases to make purchases (and meals) that are lower in fat and higher in fiber. A prototype interactive information system using instructional video programs, feedback on purchases with specific goals for change, weekly programs, and the ability to track user interactions and intended purchases was evaluated. The major dependent measure was users' actual food purchases as derived from participants' highly detailed supermarket receipts. After a 5- to 7-week baseline phase, participants were randomly assigned to an experimental or control condition for the 7- to 8-week intervention phase. A follow-up phase began 5 to 8 weeks after participants completed the intervention and discontinued use of the system. The results indicated that experimental participants, when compared to control participants, decreased high fat purchases and increased high fiber purchases during intervention, with evidence for some maintenance of effect in follow-up. Plans for increasing the use and impact of the system are discussed. 相似文献

The reliability of assessments at four and six years of age in identifying teacher rated problems in behaviour, concentration, motor skill and school achievement was investigated in a study of first-graders. Relationships between preschool data and school ability tests, and between parents' information at school start and teacher ratings were also studied. Problems noted in preschool and school were often present in more than one area. Multiple problems at four and six years were strong predictors of later school problems, but preschool assessments of separate areas could not in general predict problems in corresponding areas in school. However, cross situational concentration deficits at the age of six did reliably identify concentration problems in the first grade, at the age of seven. 相似文献

The COVID-19 pandemic provided an opportunity to investigate factors related to public response to public health measures, which could help better prepare implementation of similar measures for inevitable future pandemics. To understand individual and environmental factors that influence likelihood in engaging in personal and public health measures, three crowdsourced convenience samples from Amazon Mechanical Turk (MTurk) completed likelihood-discounting tasks of engaging in health behaviors given a variety of hypothetical viral outbreak scenarios. Experiment 1 assessed likelihood of mask wearing for a novel virus. Experiment 2 assessed vaccination likelihood based on efficacy and cost. Experiment 3 assessed likelihood of seeking health care based on number of symptoms and cost of treatment. Volume-based measures and three-dimensional modeling were used to analyze hypothetical decision making. Hypothetical public and personal health participation increased as viral fatality increased and generally followed a hyperbolic function. Public health participation was moderated by political orientation and trust in science, whereas treatment-seeking was only moderated by income. Analytic methods used in this cross-sectional study predicted population-level outcomes that occurred later in the pandemic and can be extended to various health behaviors. 相似文献

Open Dialogue is a dialogical approach focusing on the perspectives of patients and their social networks on treatment and recovery processes. As part of a larger research project, this prospective cohort study explores what promotes and hinders the development of Open Dialogue in network meetings (ODNM) based on the experiences of thirty-seven clinicians and seven supervisors. Multistage focus group interviews were used to collect data and were analysed thematically. We generated two main themes: (1) togetherness and isolation and (2) challenging and evolving. The findings show that ODNM can be developed in public mental healthcare, but this leads to both challenges and opportunities at the organisational level, such as conflicting perspectives, the difficulty of maintaining interest in ODNM, the need for committed and involved leaders, and the growing change in the traditional view of treatment, which has made clinicians collaborate more with patients and their relatives. 相似文献

Depression and anxiety are two of the most common mental disorders treated in Integrated Primary and Behavioral Healthcare programs. We investigated the within and between performance differences of mental health counselors on anxiety and depressive symptomatology in an integrated service with a sample of 1573 clients and 10 licensed professional counselors. The results of growth curves within the framework of Multilevel Modeling showed significant within and between performance differences among counselors treating anxiety and depressive symptoms. Some counselors performed better in treating anxiety symptoms while others did better treating depression. Implications for counselor education, client care, and legislation are provided. 相似文献
