Validation of the Chinese version of the Mood Disorder Questionnaire in a psychiatric population in Hong Kong

Aims:  The aim of the present study was to determine the validity of a Chinese version of the Mood Disorder Questionnaire (MDQ) as a screening instrument for bipolar disorder in a psychiatric outpatient population in Hong Kong.
Methods:  A total of 185 patients primarily being treated for mood disorders were asked to fill in the Chinese MDQ and supply other personal data during their scheduled clinic visit. The mean age was 43.0 years and 65.9% were female. A subsample of 102 randomly selected subjects, stratified by the MDQ symptom score, received a telephone-based Structured Clinical Interview for DSM-IV (SCID). Sixty-two patients (60.8%) were suffering from bipolar disorder (bipolar I, n  = 48; bipolar II, n  = 9; bipolar disorder not otherwise specified, n  = 5), 35 (34.3%) from depressive disorder, and one (1.0%) from substance dependence, while four (3.9%) were unaffected by either mood or alcohol/substance use disorder. The internal consistency, factor structure and operating characteristics of the Chinese MDQ were analyzed.
Results:  The internal consistency of the Chinese MDQ, evaluated using Cronbach alpha, was 0.82. Principal component analysis with varimax rotation indicated an 'energized-activity' factor and an 'irritability-racing thoughts' factor, which explained 47.2% of the rotated variance. The optimal cut-off was seven or more manic symptoms occurring within the same time period, which yielded a sensitivity of 0.73 and a specificity of 0.88 for detecting bipolar disorder. An additional criterion that the symptoms cause impairment resulted in significant loss of sensitivity.
Conclusion:  The Chinese MDQ is a valid screening instrument for bipolar disorder in a psychiatric outpatient population.     

Validation of the Chinese version of the strengths and difficulties questionnaire in Hong Kong

Background  

The strengths and difficulties questionnaire (SDQ) is now one of the most commonly used instruments for screening child psychiatric morbidities. Psychometric studies in the West affirm its reliability and validity, but similar studies are scarce among non-Western populations. This is an important gap because cultural differences can influence how children’s behaviours are perceived and rated. This study explores the psychometric properties of the Chinese version of the SDQ among children in Hong Kong.     

Validation of the Greek version of the Health of the Nation Outcome Scales for Elderly People (HoNOS65+, version 3)

Objectives: There is a growing need for evaluation of the results of mental health services and clinical treatment in older people, but evidence for effectiveness is limited in Greece. The Health of the Nations Outcome Scales for Elderly People (HoNOS65+) are promising instruments for the assessment of mental, physical and social health in older persons. They have been translated into the Greek language but have not been validated. The aim was to assess the inter-rater reliability, intraclass correlation, concurrent validity, internal consistency and sensitivity to change of HoNOS65+ in a Greek sample of older people with mental health problems.

Method: Two samples, one of inpatients in a psychiatric hospital and the other of older people living in the community were used. In order to test the extent to which the HoNOS65+ were sensitive to change the first sample was reassessed after two months and the second after three months. For each participant HoNOS65+ were completed by two independent raters, and the clinician rated blindly each participant on the Stockton Geriatric Rating Scale and a scale which measured behavioural, physical, cognitive and emotional status.

Results: In both groups (inpatients n?=?50, community n?=?65), the inter-rater reliability, intraclass correlation and concurrent validity were high while internal consistency of the scales taken together was low. At reassessment in 98 participants, HoNOS65+ showed changes comparable to clinician ratings.

Conclusion: The Greek version of HoNOS65+ can achieve high levels of reliability, validity and sensitivity to change for measuring outcomes in older people with mental health problems.     

A validation study of the Chinese version of the Autism Parenting Stress Index (C-APSI) in Hong Kong

BackgroundParents of children with Autism Spectrum Disorders are facing higher parenting distress than typical parents. Despite its economic prosperity, Hong Kong has only recently developed an early intervention service by the government for children with autism. Such a change provides an opportunity to develop better psychometric screening measuring parenting distress. Existing scales measuring parenting distress are often found to have high monetary and time costs, resulting in parent distress being neglected in treatment planning.MethodTo address this as well as language-based challenges, a Chinese version of an existing 13-item Autism Parenting Stress Index (C-APSI) was developed and validated in a Hong Kong clinical (n = 112) and control (n = 65) samples.ResultsThe translated version showed satisfactory test-retest reliabilities. Although the previously found factor structure could not be replicated, the scale’s internal consistency and test-retest reliability was satisfactory. Parenting distress did not correlate with objective measures of cognitive functioning, but it did with subjective reports of daily functioning of autistic children, age of parents and family income.ImplicationsThe current study bridges the gap for the need of a validated scale for screening or quick assessment for Hong Kong Chinese parents with autistic children. The marked difference in mean scores compared to the US sample suggests cultural differences in how parents perceive the distress arising from taking care of their children.     

Validation of the Cambridge Prospective Memory Test (Hong Kong Chinese version) for people with stroke

This study aimed to develop and evaluate a Hong Kong Chinese version of the Cambridge Prospective Memory Test (CAMPROMPT-HKCV). Thirty-three subjects at least one year post-stroke participated in the study. They were simultaneously rated on version A of the CAMPROMPT-HKCV by two testers to establish its internal consistency and inter-rater reliability. Raters used the parallel versions of the test (A and B), in rating 10 patients within 2 weeks to establish the parallel form reliability. Another 10 were also assessed on the same day using both version A of the CAMPROMPT-HKCV and the Rivermead Behavioural Memory Test–Chinese version (RBMT-CV) to establish concurrent validity. A new group of 40 stroke patients and 44 healthy controls was recruited to establish its sensitivity and specificity. Results indicated that test–retest reliability on time-based, event-based and total scores, and inter-rater reliability for versions A and B of the test were high. Cronbach's alpha of the event-based score was higher than that of the time-based score. The reliability and concurrent validity of the parallel forms were established. There was a significant difference in performance on CAMPROMPT-HKCV (version A) between the stroke group and the healthy control group. ROC analysis showed that the ability of the cut-off CAMPROMPT-HKCV (total score) to differentiate PM problems was 20.5 (out of 36) with sensitivity at 95.5% and specificity at 55.9%. Further study in developing stratified norms across different age groups in Chinese-speaking stroke patients is recommended.     

Validation study of the Chinese version of the neuropsychiatric inventory (CNPI)

BACKGROUND: More validated instruments for assessment of behavioral and psychological symptoms of dementia are required to facilitate local dementia research. METHOD: The psychometric properties of the Chinese version of the neuropsychiatric inventory (CNPI) were tested in a sample of 62 dementia outpatients. The concurrent validity was tested by measuring the Spearman correlation between CNPI subscales with the appropriate subscales of BEHAVE-AD and the Chinese Hamilton rating scale of depression (CHDS). The internal consistency reliability, false-negative rates of the screening questions of CNPI and inter-rater reliability were determined. RESULT: Most CNPI behavioral domains achieved significant correlation with the corresponding BEHAVE-AD and CHDS subscales. Cronbach alpha for the overall reliability was 0.84. The false-negative rates of the screening question were acceptable except for the dysphoria, sleep and appetite domains. The inter-rater reliability was satisfactory with intraclass correlation coefficient of all subscales above 0.9. CONCLUSION: The study demonstrated the applicability of the CNPI in assessing the neuropsychiatric manifestations of dementia in the Chinese community.     

Validation of the virtual-reality prospective memory test (Hong Kong Chinese version) for individuals with first-episode schizophrenia

This study was performed to examine the psychometric properties of a Virtual-Reality Prospective Memory Test (Hong Kong Chinese version; VRPMT-CV). The VRPMT was administered to 44 individuals with first-episode schizophrenia. The test was administered again 2 weeks later to establish test-retest reliability. The concurrent validity of the VRPMT was evaluated by examining the correlations between the VRPMT score and the score on the Chinese version of the Cambridge Prospective Memory Test (CAMPROMPT-CV). The performance of individuals with schizophrenia on the VRPMT was also compared with that of 42 healthy control subjects to examine the test’s sensitivity and specificity. The intraclass correlation for test–retest reliability of the total VRPMT–CV score was 0.78 (p?=?.005). A significant correlation was found between the total VRPMT-CV score and the total CAMPROMPT-CV score (r?=?0.90; p?相似文献   

Validation of the Korean version of the Boston Autonomic Symptom Questionnaire

Background and PurposeThe Boston Autonomic Symptom Questionnaire (BASQ) is a quantitative tool using a numeric rating scale to assess the symptoms of systemic dysautonomia, including cardiovascular, gastrointestinal, urinary, sudomotor, vasomotor, and sexual functions. The aim of this study was to validate the Korean version of the BASQ (KBASQ).MethodsProspectively enrolled subjects who submitted to autonomic function tests, including tests for cardiovagal, adrenergic, and sudomotor functions, also completed the KBASQ and the Korean version of the Orthostatic Grading Scale (KOGS), a validated questionnaire or assessing orthostatic symptoms.Twenty-eight subjects completed the KBASQ twice to assess test-retest reliability. We classified the subjects to dysautonomia or normal control group according to dysautonomic symptoms and the results of autonomic function tests.ResultsThis study enrolled 225 subjects aged 54.0±18.1 years (mean±standard deviation), with a male/female ratio of 1/1.03. The internal validity of the KBASQ was excellent (Cronbach''s α=0.922), and that of each of its subscales ranged from excellent to acceptable (Cronbach''s α=0.709–0.952). The test-retest reliability was good, with correlation coefficients ranging from 0.354 to 0.917. The subcategory scores for the KBASQ were significantly higher in the dysautonomia group than in the normal control group. There were significant correlations among the items in the KBASQ and KOGS. There was also a significant correlation between KBASQ scores and the results of the autonomic function tests.ConclusionsThe internal validity and reliability of the KBASQ were good, indicating that it may be a useful screening tool for the systematic evaluation of autonomic symptoms in patients with dysautonomia.     

Self-reported consumer satisfaction in mental health services: Validation of a self-rating version of the UKU-Consumer Satisfaction Rating Scale

The UKU-Consumer Satisfaction Rating Scale (UKU-ConSat) for the evaluation of consumer satisfaction in mental health services was constructed for assessments by independent professional interviewers. In the present study, a patient self-reported version of the scale is validated against the original version. The Spearman's rank correlation between single items, subscores and the total of the original scale and the self-assessment version was found to be good. Another main finding was an acceptable unidimensionality of the self-rating version of the UKU-Consumer Satisfaction rating scale, evaluated by a Mokken analysis. Furthermore, the internal consistency by Cronbach's alpha was found to be satisfactory. The results show that the patient self-rating version is psychometrically sound and therefore suitable for use in ordinary clinical practice. Being a part of a concept for continuous quality control and development in mental health services, the self-rating version of the UKU-ConSat promotes an open collaborative dialogue between professionals and users. A further advantage is that it saves professional time.     

Validation and factor structure of the Thai version of the EURO-D scale for depression among older psychiatric patients

Objectives: To assess the concurrent and the construct validity of the Euro-D in older Thai persons.

Method: Eight local psychiatrists used the major depressive episode section of the Mini International Neuropsychiatric Interview to interview 150 consecutive psychiatric clinic attendees. A trained interviewer administered the Euro-D. We used receiver operating characteristic (ROC) analysis to assess the overall discriminability of the Euro-D scale and principal components factor analysis to assess its construct validity.

Results: The area under the ROC curve for the Euro-D with respect to major depressive episode was 0.78 [95% confidence interval (CI) 0.70–0.90] indicating moderately good discriminability. At a cut-point of 5/6 the sensitivity for major depressive episodes is 84.3%, specificity 58.6%, and kappa 0.37 (95% CI 0.22–0.52) indicating fair concordance. However, at the 3/4 cut-point recommended from European studies there is high sensitivity (94%) but poor specificity (34%). The principal components analysis suggested four factors. The first two factors conformed to affective suffering (depression, suicidality and tearfulness) and motivation (interest, concentration and enjoyment). Sleep and appetite constituted a separate factor, whereas pessimism loaded on its own factor.

Conclusion: Among Thai psychiatric clinic attendees Euro-D is moderately valid for major depression. A much higher cut-point may be required than that which is usually advocated. The Thai version also shares two common factors as reported from most of previous studies.     

Patient satisfaction and treatment environment: A 20-year follow-up study from an acute psychiatric ward

The aim of this study was to examine to what extent the different subscales of the Ward Atmosphere Scale (WAS) are related to patient satisfaction on wards for psychotic patients. We wanted to examine if it was possible to replicate previous findings from cross-sectional studies and improve the understanding of which of the WAS subscales that should be considered the most important for patient satisfaction. From 1981 through 2000, the ward atmosphere, in an acute psychiatric ward, was evaluated 11 times with the Ward Atmosphere Scale (WAS). A total of 129 patients completed the WAS as well as a General Satisfaction Index (GSI) comprising three items. Z-scores were calculated to describe the fluctuations in the GSI and the WAS subscales. Four of the WAS subscales, Involvement, Practical orientation, Angry and aggressive behavior and Staff control, strongly co-varied with patient satisfaction. Unexpectedly, the Support and Order and organization subscales correlated only moderately with patient satisfaction. The remaining five WAS subscales (Spontaneous behavior, Autonomy, Personal problem orientation, Program clarity and Staff attitude to expressed feelings) were only weakly correlated with patient satisfaction. This study confirms that four of the six assumedly most important WAS subscales are strongly related to patient satisfaction on wards for psychotic patients. Changes in these WAS subscales seems to be paralleled by changes in patient satisfaction in the expected direction.     

Norwegian version of the Mini-International Neuropsychiatric Interview: Feasibility,acceptability and test-retest reliability in an acute psychiatric ward

ObjectiveTo assess the feasibility, patient and clinician acceptability and test-retest reliability of the Mini-International Neuropsychiatric Interview (MINI) used by non-psychiatrists in an acute psychiatric ward.MethodOf 268 consecutive patients included in a cross-sectional study, 176 (66%) completed MINI, and were compared to patients not interviewed. Patients and clinicians were questioned about the interview, using Visual Analogue Scales (VAS). For 38 patients, test-retest reliability was assessed with Cohen's kappa and observed agreement.ResultsMINI was not feasible for all patients. Among factors associated with not being interviewed were early discharge, psychosis, substance use and involuntary admissions. Although evaluations by patients and clinicians completing the postinterview questionnaire varied, MINI was generally perceived as being useful and feasible. Psychotic symptoms were associated with a less positive experience with MINI for both patients and clinicians. In the test-retest analyses, kappa values indicated excellent agreement for six diagnoses, fair to good for six and poor for seven, whereas observed agreement was 75% or above for all disorders.ConclusionAmong patients admitted to an acute psychiatric ward willing and able to complete the interview, MINI was well accepted by patients and clinicians, and has moderately good test-retest reliability.     

Validation of an IVRS version of the MADRS

Interest in self-reported measures of depression in clinical trials has grown in recent years. This study compared the reliability and validity of the clinician-administered Montgomery-Asberg Depression Rating Scale (MADRS) to a computer-administered version administered over the telephone using Interactive Voice Response (IVR) technology.Sixty subjects were administered both the clinician- and computer-administered versions of the MADRS in a counter-balanced order. A subsample of 20 patients was reassessed 24 h later by both methods.Mean score differences between IVR and clinician were not statistically significant (<1 point) and a high correlation was found between forms (r = .815, p < .001). Reliability measures (Cronbach’s Alpha and 24-h test-retest) were comparable. Clinicians rated the severity of subjects’ sadness and pessimistic thoughts lower than subjects self-report.The data obtained in this pilot study provide support for the equivalence between the clinician and IVR versions of the MADRS.     

Patient satisfaction and ward atmosphere during a crisis in an open psychiatric ward

Background There is great need for useful indicators of quality of care for inpatient psychiatric treatment. The study examines whether patient satisfaction and ward atmosphere can be used as a means of evaluating an assumed decline in quality of care during a crisis in an open psychiatric ward. Methods Twice a year for 2 years ten patients filled out a standardized patient satisfaction questionnaire developed by the Swedish Institute for Health Services Development (SPRI) on their day of departure. At the same time all the patients in the ward evaluated the ward atmosphere using the Ward Atmosphere Scale (WAS). In the third study period the ward went through a crisis where quality of care was expected to be lower. Results The SPRI questionnaire confirmed the decline in patients' perceived quality of care on six of 41 questions, WAS was markedly lower on five of ten subscales. Conclusions Both WAS and the SPRI questionnaire gave useful information on how the ward was affected by the crisis. WAS seemed to be a more sensitive way of measuring quality of care, while the SPRI questionnaire indicated more clearly the practical consequences. Accepted: 12 August 2001     

Validation of the parent version of the World Health Organization Adult ADHD Self-Report Scale for adolescents

Objective: To investigate the validity of a parent version of the World Health Organization Adult Attention-Deficit/Hyperactivity Disorder (ADHD) Self-Report Scale for adolescents (ASRS-AP) and the 6-question screening version (ASRS-AP-S). Methods: Adolescent psychiatric outpatients (N?=?112, mean age 15 years, 40% boys) and their parents were interviewed with the Kiddie Schedule of Affective Disorders and Schizophrenia (K-SADS), and the parents reported on the ASRS-AP/ASRS-AP-S. Results: Internal consistency (Cronbach’s alpha) was 0.93 for ASRS-AP and 0.85 for ASRS-AP-S, 0.91 and 0.87 for the inattention subscale, and 0.91 and 0.72 for the hyperactivity subscale, respectively. The concurrent validity (Spearman’s correlation coefficient) between the total K-SADS ADHD symptom severity score and the sum of the score on the ASRS-AP/ASRS-AP-S was 0.75 and 0.66, respectively. Diagnostic accuracy measures for the ASRS-AP and ASRS-AP-S were 78% and 80% sensitivity, 75% and 74% specificity, 73% and 71% positive predictive value (PPV), and 81% and 82% negative predictive value (NPV), respectively. Conclusions: The ASRS-AP and ASRS-AP-S showed high internal consistency and concurrent validity in relation to total K-SADS ADHD symptom severity score. Both scales showed favourable diagnostic accuracy measures.     

Chinese cultural dynamics of unemployability of male adults with psychiatric disabilities in Hong Kong

Work and employment has long been regarded as crucial for the mental health of human beings. Unemployment may lead to deterioration of physical and mental health. Nevertheless, for adults with psychiatric disabilities, discontinuity of employment is common. They may have various reasons to discontinue their employment. In Hong Kong, only 2.5% of people with psychiatric disabilities discharged from sheltered workshops are able to seek open employment. By means of illustration, the authors will show that traditional Chinese work culture tends to reinforce the discontinuity of employment of adult males with psychiatric disabilities. In Chinese culture, work is a means to occupy time, control misbehavior, show consistency of words and deeds, and to glorify parents and ancestors. All these factors contribute to the fulfillment of an adult male role and identity in traditional Chinese culture. In this case history, instead of finding realistic employment, a male adult with psychiatric disability tried to indulge himself in what he felt was his ideal job to fulfill all requirement as an adult male in Chinese culture. The imaginative ideal job gave him excuses to discontinue open employment. Its implications to vocational rehabilitation with male adults with psychiatric disability are also discussed.     

Age- versus time-comparative self-rated health in Hong Kong Chinese older adults

OBJECTIVES: The main objectives were to examine the relation between age-comparative (self vs others of same age) self-rated health (SRH) and time-comparative (self this year vs last year) SRH, and to evaluate which was more strongly associated with specific physical health problems. METHODS: Cross-sectional data on two SRH measures and various physical health problems from 18749 male and 37413 female clients aged 65 or over from 18 Elderly Health Centres in Hong Kong were analysed using logistic regression with adjustment for potential confounders. RESULTS: Men were more likely to report 'better' and less likely to report 'worse' SRH than women. 'Normal' was the most common option but the proportions choosing this decreased with age on both SRH measures. There was a fairly weak but statistically significant correlation between these two measures, with Kappa coefficients of 0.125 and 0.167 for men and women, respectively. For both men and women, there were significantly positive linear trends between age-comparative SRH options from 'better' to 'worse' and physical health problems, such as respiratory diseases, musculoskeletal diseases, any active chronic diseases, functional disability, depressive symptoms, taking medication regularly, and admission to hospital last year. However, for time-comparative SRH, those who rated 'normal' had the smallest odds ratios in all of the physical health problems above than those who rated 'better' or 'worse'. CONCLUSIONS: The two SRH measures correlated with each other weakly but significantly. Age-comparative SRH was linearly, and time-comparative SRH was curvilinearly associated with physical health problems.
