精神医学科研方法(3):中国精神卫生研究中工具和量表的使用(英文)

Almost all mental health research involves the use of instruments or scales.These are employed to make diagnoses;to measure the severity of symptoms;to assess knowledge,attitudes and behaviors;and for a wide range of other purposes.Much of the reported mental health research in China employs Chinese versions of scales from the     

Quality of life instruments used in mental health research: Properties and utilization

Quality of life (QoL) assessment is increasingly used in mental health. Multiple instruments exist, but the conditions for choosing one instrument over another for purposes of a specific study are not clear. We performed a systematic review to identify the QoL instruments used in mental health. The instruments were systematically described regarding their intrinsic properties (e.g., generic v. disease-specific) and their characteristics of utilization in studies (e.g., study objectives). Using cluster analyses, we investigated the existence of similar instruments with respect to each of these sets of characteristics and studied potential links between instruments' intrinsic properties and their characteristics of utilization. We included 149 studies in which 56 distinct instruments were used. Similarities were found among instruments in terms of their intrinsic properties as well as their characteristics of utilization, leading to the construction of four clusters of instruments in each case. However, no relevant links were identified between instruments' intrinsic properties and their characteristics of utilization, suggesting that the choice of QoL instruments did not depend on their properties. A consensus about common QoL instruments must be reached to facilitate the choice of instruments, the comparison of results and thus to have an impact on clinical and policy decision-making.     

Fee scales in mental health clinics

The range of fees which families of identical income might be required to pay at different mental health clinics is deplorably wide. Data have been collected regarding fee scales at a small but representative group of clinics which offer psychiatric service to children. Implicit is a plea for the establishment of some central committee which would furnish a nationwide recommendation as to simple and relatively uniform sliding fee scales for nonprofit mental health clinics irrespective of their location or of the socioeconomic characteristics of their communities.     

Current use of depression rating scales in mental health setting

Objective

This study was to investigate the current use of depression rating scales by psychiatrists and clinical psychologists in Korea.

Methods

The questionnaires from many psychiatrists and clinical psychologists were included in the analysis. The questionnaire was composed of items about examining the percentage of patients clinically using depression rating scales, reasons for not use of them, the degree of satisfaction, the perceived agreement rate between the result of depression rating scales and doctor''s clinical interview in the evaluation of patients with depressive symptoms. Data were analyzed by χ² and independent t-test.

Results

The clinical use of depression rating scales was more frequent in the psychologists than in the psychiatrists. The purposes for using depression rating scales were assessed into six areas, there was no significant difference in between two groups, and both groups pointed out their purpose as rating of severity and screening. The reasons for not using scales were that their interview may be sufficient for diagnosis and assessment of depressive patients and they are not familiar with the use of depression rating scales. The psychiatrists usually prefer the Beck Depression Inventory (BDI), Hamilton Depression Rating Scale and Symptom Checklist 90-Revision (SCL-90-R) in order of frequency, and the clinical psychologists are more likely to use the BDI, Minnesota Multiphasic Personality Inventory and SCL-90-R. Overall rate of satisfaction in the use of the scales was 67.29±14.45% and overall perceived agreement rate was 70.89±16.45%.

Conclusion

Currently used depression rating scales at the clinical practice were not various. Therefore, to heighten clinicians'' utility of these depression rating scales measures, either educational efforts or advertisements, or both, will be necessary to spread them wildly.     

Predicting physical health: implicit mental health measures versus self-report scales

Researchers have traditionally relied on self-report questionnaires to assess psychological well-being, but such measures may be unable to differentiate individuals who are genuinely psychologically healthy from those who maintain a facade or illusion of mental health based on denial and self-deception. Prior research suggests that clinically derived assessment procedures that assess implicit psychological processes may have advantages over self-report mental health measures. This prospective study compared the Early Memory Index, an implicit measure of mental health/distress, with a range of familiar self-report scales as predictors of physical health. The Early Memory Index showed significant prospective associations with health service utilization and clinically verified illness. In contrast, self-report measures of mental health, perceived stress, life events stress, and mood states did not predict health outcomes. The findings highlight the limitations of self-report questionnaires and suggest that implicit measures have an important role to play in mental health research.     

Evaluative research in community mental health

This paper compares evaluative research to program evaluation by defining and describing each. A case example using the scientific design and methodology of evaluative research to evaluate a specific community mental health program is also presented. Project design is discussed in light of the awareness that the mental health needs of communities do not always bend to fit the requisite of precise scientific procedure. Some ideas on methodological considerations reflect that normal research tools can be useful to achieve a valid study. Implications for the application of evaluative research to community mental health needs are also identified.     

Use of mental health services in Chile

OBJECTIVE:S: To address the growing burden of mental illness in Latin America, a better understanding of mental health service use and barriers to care is needed. Although many Latin American countries have nationalized health care systems that could potentially improve access to care, significant barriers to care remain. The authors report the results of a study examining mental health service utilization in the general population of Chile. METHODS: The data were drawn from the Chile Psychiatric Prevalence Study, a national household survey of 2,987 persons aged 15 years and older conducted in 1992-1999. As part of the survey, psychiatric diagnoses were obtained by using the Composite International Diagnostic Interview, and respondents were asked about their use of general and mental health care services in the past six months and about their experience of barriers to treatment. RESULTS: More than 44 percent of respondents reported use of any health care services in the past six months, and 20 percent reported use of mental health services. Of the respondents who met criteria for a psychiatric disorder, a large proportion (62 percent) did not receive mental health care. Increasing severity of the psychiatric disorder correlated with increasing frequency of overall help seeking, but only a small proportion of the respondents with a psychiatric disorder sought specialized mental health services. Regional disparities and inequities in access to care were found. In addition, indirect barriers to mental health care, such as stigma and misconceptions about the course of psychiatric disorders, were important deterrents to service utilization, particularly among persons with lower socioeconomic status. CONCLUSIONS: To reduce the burden of mental illness in Chile, additional efforts are needed to address both the direct and the indirect barriers to mental health care, including regional inequities in access to care.     

Qualitative research methods in mental health

As the evidence base for the study of mental health problems develops, there is a need for increasingly rigorous and systematic research methodologies. Complex questions require complex methodological approaches. Recognising this, the MRC guidelines for developing and testing complex interventions place qualitative methods as integral to each stage of intervention development and implementation. However, mental health research has lagged behind many other healthcare specialities in using qualitative methods within its evidence base. Rigour in qualitative research raises many similar issues to quantitative research and also some additional challenges. This article examines the role of qualitative methods within mental heath research, describes key methodological and analytical approaches and offers guidance on how to differentiate between poor and good quality qualitative research.     

Operations research in mental health administration

Operations research methods have been powerful analytical tools for administrators in the military, industry and business. Possibly holding major promise for mental health administrators, such methods are applied in this study to a sustaining-care problem.     

Adolescent mental health in China

Adolescent Mental Health in China is the responsibility of the wider society and is supported by social, educational and health care resources. With limited facilities, China emphasizes community mental health care, with prevention and health promotion as priorities. Mental health is considered in the context of an orderly socialist society with stable family life supported by the state. Society is currently influenced by a mixture of Communist ideology, ancient tradition and newer Western approaches. Difficulties in reconciling these factors are affecting the attitudes and behaviour of China's youth.     

Overview of mental health services research

Mental health services research is a new field of inquiry that can be helpful to clinicians and policymakers.
