Background/Objective: The World Health Organization's diagnostic guidelines for ICD-11 mental and behavioural disorders must be tested in clinical settings around the world to ensure that they are clinically useful and genuinely global. The objective is evaluate the inter-rater reliability and clinical utility of ICD-11 guidelines for psychotic, mood, anxiety- and stress-related disorders in Mexican patients. Method: Adult volunteers exhibiting the selected symptoms were referred from the pre-consultation unit of a public psychiatric hospital to an interview by a pair of clinicians, who subsequently assigned independent diagnoses and evaluated the clinical utility of the diagnostic guidelines as applied to each particular case, on the basis of a scale developed for this purpose. Results: 23 clinicians evaluated 153 patients. Kappa scores were strong for psychotic disorders (.83), moderate for stress-related (.77) and mood disorders (.60) and week for anxiety and fear-related disorders (.43). A high proportion of clinicians considered all diagnostic guidelines to be quite to extremely useful as applied to their patients. Conclusions: ICD-11 guidelines for psychotic, stress-related and mood disorders allow adequate inter-rater consistency among Mexican clinicians, who also considered them as clinical useful tools.  相似文献

The reciprocal nature of the relationship between depression and personality traits (e.g., self-esteem, neuroticism) is still elusive (e.g., vulnerability and scar models). The aim of this study was to examine the longitudinal reciprocal effects between self-esteem and depressive mood in older adults. 757 participants aged 64–97 years assessed 4 times over a six-year period. Cross-lagged models were estimated using SEM. Our findings showed a relative stability over a six-year period of both self-esteem and depressive mood. There were no cross-lagged reciprocal effects between self-esteem and depressive mood over time, thereby rejecting both vulnerability and scar models. It means that self-esteem and depressive mood do not predate each other in old age. These results suggest a developmental phenomenon in which self-esteem and depressive mood follow two parallel and stable developmental trajectories through old age.  相似文献

ObjectiveIn this qualitative longitudinal study we assess the retirement process of Olympic athletes. We aim to evaluate the influence that following a dual career or being exclusively focused on sport can have in this process. We compare athletes' prospective views before retirement (Torregrosa, Boixadós, Valiente, & Cruz, 2004) with their retrospective accounts ten years later. This allows us to assess athletes' accuracy in predicting the process and its outcomes in relation to the trajectory followed.DesignWe designed a qualitative longitudinal study (Epstein, 2002) conducting semi-structured interviews.MethodFifteen Olympic athletes were interviewed twice. Thematic analysis was performed on the qualitative data comparing prospective views and retrospective accounts of: (a) retirement planning, (b) voluntary termination, (c), multiple personal identities, (d) availability of social support, and (e) active coping strategies.ResultsTen athletes reported positive transitions related to their favorable approach to the five categories above. Most athletes reporting positive transitions followed dual careers (i.e., parallel or convergent trajectories). Five out of fifteen athletes reported unexpected difficulties in the transition. Four of these followed a linear trajectory during their sporting career. A clear view of retirement in the prospective interviews also facilitated retirement for an athlete following a linear trajectory. While a diffuse view of retirement in the prospective interview signaled future difficulties.ConclusionResults from this qualitative longitudinal study suggest that promoting dual careers in elite sport and working on the prospective view of retirement can facilitate retirement from elite sport and the transition to an alternative professional career.  相似文献

本研究分别在中国和日本对一岁半到二岁半的婴儿进行自然观察,分析了婴儿之间围绕着某些资源而发生的交涉行为和交换性行为的发生过程及其发展上特点。主要结果有①中日婴儿到2岁左右时开始出现交涉行为和交换性行为,但在该年龄阶段并不占有主导地位。②该年龄阶段婴儿的交换性行为还不能说是完整意义上的交换,属于“前交换行为”。③对于获得对方的东西来说,该年龄阶段婴儿的交涉行为和交换性行为并不是很有效的方式。④我们进行观察的中国幼儿园托儿班的婴儿其交涉行为和交换性行为的出现早于日本保育园的婴儿,但从交涉行为出现的比例来看,日本婴儿采用交涉行为的倾向比中国婴儿更明显。  相似文献

采用社会支持观察研究范式及问卷调查相结合的方式,对41对新婚夫妻进行提供支持、接收支持以及婚姻满意度测量,探讨提供支持与配偶接收支持之间关系的性别效应及婚姻满意度的情感覆盖效应.结果显示:①妻子提供的支持可以预测丈夫接收到的支持,但丈夫提供的支持不能预测妻子接收到的支持.②妻子接收到的支持与丈夫提供的支持之间的不一致受婚姻满意度的情感覆盖效应的调节,而丈夫则没有这种效应.结论:妻子在对丈夫的支持行为进行解码时,更多受到婚姻满意度的情感覆盖效应影响.  相似文献

Qualitative interviews were conducted with mothers (N = 47) who had disclosed their HIV status to their children. The majority of mothers explicitly told their child not to disclose to other people that she was HIV-positive because they feared repercussions in the way of stigma and ostracism for both themselves and their child. Approximately one-fourth of the mothers identified safe people, to whom their child could discuss her serostatus, such as family members, health care providers, or therapists. The majority of the children respected their mothers' wishes; only four children disclosed to someone after being explicitly told not to do so. A significant number of children expressed concerns about their friends finding out, fearing that they would be ostracized or that it would be assumed they were also infected. In addition, the children did not want others to find out because they wanted to protect their mothers. The burden of keeping the secret of their mothers' serostatus does seem to be a stressor for some of the children.  相似文献

Background/Objectives: Binge Eating Disorder (BED) is often associated with obesity. In order to identify the variables that allow to better detect the presence of BED, people with overnutrition were compared with and without BED in the presence of cognitive conflicts, eating symptoms and anxious-depressive symptoms. The inclusion of cognitive conflicts had been relevant in bulimia studies but had not been investigated with respect to BED. Method: Two groups with obesity were evaluated, one without BED (OB, n = 54) and the other with BED (OB-BED, n = 48), using a social-demographic questionnaire as well as a semi-structured interview to assess BED, questionnaires (DASS-21, EDE-Q, EEQ) and the Repertory Grid Technique. Results: Overall, the OB-BED group presented more conflicts and more symptoms. The model that best differentiated between the groups included emotional eating and level of cognitive conflicts, correctly classifying 91.4% of the sample. Conclusion: These results highlight the role played by cognitive conflicts and emotional eating as differentiating elements between OB and OB-BED, with a high level of predictive accuracy.  相似文献

Background/Objective: Colorectal and gynecologic cancer survivors are at cardiovascular risk due to comorbidities and sedentary behaviour, warranting a feasible intervention to increase physical activity. The Health Action Process Approach (HAPA) is a promising theoretical framework for health behaviour change, and wearable physical activity trackers offer a novel means of self-monitoring physical activity for cancer survivors. Method: Sixty-eight survivors of colorectal and gynecologic cancer will be randomised into 12-week intervention and control groups. Intervention group participants will receive: a Fitbit Alta? to monitor physical activity, HAPA-based group sessions, booklet, and support phone-call. Participants in the control group will only receive the HAPA-based booklet. Physical activity (using accelerometers), blood pressure, BMI, and HAPA constructs will be assessed at baseline, 12-weeks (post-intervention) and 24-weeks (follow-up). Data analysis will use the Group x Time interaction from a General Linear Mixed Model analysis. Conclusions: Physical activity interventions that are acceptable and have robust theoretical underpinnings show promise for improving the health of cancer survivors.  相似文献

This phenomenological study assessed master-level students’ experiences of using photovoice, a creative learning activity, in a race-based multicultural counseling course. Students were asked to engage in weekly written reflections regarding a course-related photographic image, with the goal of more deeply processing cognitive and affective reactions to the course. Data analyzed included focus groups, student written responses, and photos. Findings indicated use of photovoice as a means for processing cognitions, which allowed students to deepen learning by extending a racialized lens outside of the classroom. Students also indicated use of the tool to process emotional reactions at various stages of the course, allowing learners to creatively and visually express feelings as they surfaced.  相似文献
