ABSTRACT OBJECTIVE To assess the internal consistency of the measurements of the Self-Reporting Questionnaire (SRQ-20) in different occupational groups. METHODS A validation study was conducted with data from four surveys with groups of workers, using similar methods. A total of 9,959 workers were studied. In all surveys, the common mental disorders were assessed via SRQ-20. The internal consistency considered the items belonging to dimensions extracted by tetrachoric factor analysis for each study. Item homogeneity assessment compared estimates of Cronbach’s alpha (KD-20), the alpha applied to a tetrachoric correlation matrix and stratified Cronbach’s alpha. RESULTS The SRQ-20 dimensions showed adequate values, considering the reference parameters. The internal consistency of the instrument items, assessed by stratified Cronbach’s alpha, was high (> 0.80) in the four studies. CONCLUSIONS The SRQ-20 showed good internal consistency in the professional categories evaluated. However, there is still a need for studies using alternative methods and additional information able to refine the accuracy of latent variable measurement instruments, as in the case of common mental disorders.

Psychometric evaluations were performed on a self-perceived localization disabilities and handicaps questionnaire. Twenty individuals with normal hearing bilaterally, twenty with profound unilateral hearing impairment (UHI), and ten with any degree of bilateral hearing impairment participated. Each subject completed the questionnaire. Comparisons of the responses of the subjects with normal hearing and those with UHI revealed significant differences among the groups for both disabilities and handicaps, establishing construct validity. Cronbach's Alpha correlational analyses of the responses of all subjects with hearing impairment revealed correlations of .900 (disabilities) and .800 (handicaps), establishing internal consistency. Each participant with hearing impairment was asked to complete the questionnaire again after three weeks. Pearson's correlational analyses of the responses at time one versus time two revealed correlations of .900 (disabilities) and .700 (handicaps), establishing test/retest reliability. This questionnaire is an appropriate tool for investigating the self-perceived localization disabilities and handicaps of individuals with hearing impairment.

Introduction. Valid and feasible measures to properly assess the most impaired areas of functioning in various groups of patients with mental disorders would allow the development and evaluation of interventions designed to modify the specific environmental barriers that contribute to patients´ disability. Objective. This article seeks to evaluate the internal consistency and construct and convergent validity of the Spanish version of the World Health Organization’s Disability Assessment Schedule WHODAS 2.0, as well as its relationship with sociodemographic variables and symptomatic severity in Mexican patients with and without psychotic symptoms. Method. The WHODAS 2.0 and the Social and Occupational Functioning Assessment Scale SOFAS were administered to 153 patients with any of the following diagnoses: affective disorders, anxiety disorders, stress-related disorders, and psychotic disorders. Results. The WHODAS 2.0 showed high internal consistency in patients with psychotic symptoms (Cronbach’s alpha = .92) and without psychotic symptoms (Cronbach’s alpha = .89). Nevertheless, only in patients without psychotic symptoms, was a significant negative correlation between WHODAS (disability) and SOFAS (functioning) total scores observed, together with significant differences in WHODAS scores between those with mild and severe symptomatology. Discussion and conclusion. The WHODAS 2.0 is an adequate measure of disability in patients without psychotic symptoms. It could be used as a complementary measure of disability in those with psychotic symptoms. Further studies are required to determine other psychometric properties of the WHODAS 2.0, particularly those related to temporal stability and sensitivity to change.

A cross-sectional population-based study was conducted to identify the prevalence of common mental disorders and verify the association with chronic non-communicable diseases (NCDs) and the self-reported number of chronic diseases. The Self-Reporting Questionnaire (SRQ-20) was applied in a multi-stage random sample of 1,276 adults aged 40 and older. Socio-demographic, behavioral, and health-related variables were also obtained using a structured questionnaire. Prevalence of common mental disorders was 30.2%. Lower schooling and social class and the 46-55-year age bracket were associated with psychiatric morbidity. Each chronic illness was independently associated with common mental disorders. However, a stronger association was found between common mental disorders and the total number of self-reported chronic conditions, with a prevalence ratio of 4.67 (95%CI: 3.19-6.83) for five or more self-reported NCDs. The current study emphasizes the importance of common mental disorders in chronically ill patients, particularly in those with more total chronic conditions.

BackgroundThere are few studies of mental ill health among young people in developing countries.AimsTo measure the prevalence of common mental disorders among low-income young people in the city of Cali, Colombia and to examine associations with violence and social capital.MethodThe Self-Reporting Questionnaire was administered to 1057 young people aged 15–25 years. Social capital, violence, alcoholism and socio-demographic variables were also measured.ResultsWe found 255 young people (24%) with common mental disorders. Being a woman, having limited education and experiencing high levels of violence were the main risk factors for common mental disorders. Social capital did not emerge as a risk factor.ConclusionsA large burden of mental ill health among young people was found; this requires urgent interventions and more research on the mechanisms which link mental health and violence.

Background. The Self-Reporting Questionnaire (SRQ-20) is widely used for evaluating common mental disorders. However, few studies have evaluated the SRQ-20 measurements performance in occupational groups. This study aimed to describe manifestation patterns of common mental disorders symptoms among workers populations, by using latent class analysis.Methods. Data derived from 9,959 Brazilian workers, obtained from four cross-sectional studies that used similar methodology, among groups of informal workers, teachers, healthcare workers, and urban workers. Common mental disorders were measured by using SRQ-20. Latent class analysis was performed on each database separately.Results. Three classes of symptoms were confirmed in the occupational categories investigated. In all studies, class I met better criteria for suspicion of common mental disorders. Class II discriminated workers with intermediate probability of answers to the items belonging to anxiety, sadness, and energy decrease that configure common mental disorders. Class III was composed of subgroups of workers with low probability to respond positively to questions for screening common mental disorders.Conclusions. Three patterns of symptoms of common mental disorders were identified in the occupational groups investigated, ranging from distinctive features to low probabilities of occurrence. The SRQ-20 measurements showed stability in capturing nonpsychotic symptoms.

Objectives: Over the last 15 years, adequate psychometric properties of the different versions of the Dominic led to the development of the Dominic Interactive for Adolescents (DIA). The DIA is a Diagnostic and Statistical Manual of Mental Disorders (DSM), Fourth Edition, Text Revision-based self-administered computerized pictorial instrument for assessing the most frequent mental disorders in adolescents aged 12 to 15 years. Our study aims to verify the internal consistency, the test-retest estimate of reliability, and the criterion-related validity of this instrument. Method: The total sample included 607 adolescents living in the Montreal urban area recruited from the community (465 French-speaking) and the clinical population (142 French-speaking). Internal consistency was evaluated by Cronbach's alpha coefficients and test-retest estimate of reliability by the kappas and intraclass correlation coefficients (ICCs). Two criteria are indicative of criterion-related validity of the DIA: clinical judgment on the presence or absence of symptoms (scored independently by 3 judges) and the adolescents' referrals to outpatient psychiatric clinics. Results: For most symptom scales of the DIA, Cronbach's alpha coefficients varied from 0.69 to 0.89, test-retest kappas were 0.50 or greater, and ICCs ranged from 0.78 to 0.87. The criterion-related validity was demonstrated for symptoms, symptom scales, and the categories based on the symptom scale cut-off points. Conclusion: As no informant can be considered the criterion standard of psychopathology, the interview with adolescents regarding their own symptoms is necessary. Findings from our study reasonably support adequate psychometric properties of the DIA in adolescents aged 12 to 15 years.

The ability to perform basic activities of daily living (ADL) and instrumental ADL (IADL) is an essential indicator of the level of functional capacity in old age. The purpose of this paper was to evaluate reliability and validity of the self - reporting method in detecting functional difficulties among elderly persons with cardiovascular diseases. The Groningen Activity Restriction Scale was used to assess the limitations in functional capacity. The sample consisted of patients over the age of 65 with hypertensive disease, angina pectoris, ischaemic heart disease, degenerative valvular disorders, peripheral arterial disease, cardiac arrhythmias, cardiomyopathy and heart failure. The Cronbach’s alpha internal consistency coefficient was calculated for the total result. Differences in outcome with respect to age, educational level, marital status, and medical diagnoses of participants were compared by means of a t-test or one-way ANOVA. In the group of ADL, participants reported difficulties in climbing stairs (M=2.14, SD=1.07) and caring for feet and toenails (M=2.17, SD=1.27), while in the group of IADL, difficulties were present in performing heavier household chores (M=2.51, SD=1.31) as well as ironing and washing clothes (M=2.20, SD=1.29). Calculation of the Cronbach’s alpha coefficient points to a high degree of internal consistency for this scale on a chosen sample (α=0.95). The use of a validated self-reporting tool may be a valuable and reliable way for assessing the functional capacity of elderly persons with chronic diseases. The findings of this study indicate the possibility of using this method for prognostic purposes in patients with cardiovascular diseases. Introduction of instrumental support measures in a timely manner has a crucial role in delaying the progression of functional dependence.

ABSTRACT Objective: To evaluate the reliability, response capacity and validity of four scales for low back pain and correlate these scales with each other and the Self-Administered Comorbidity Questionnaire (SACQ). Methods: We evaluated the psychometric properties of four previously selected scales for low back pain: the Roland-Morris Disability Questionnaire (RMDQ), the Quebec Back Pain Questionnaire (QBPDS), the Waddell Disability Index (WDI) and the Back Pain Functional Scale (BPFS) and Self-Administered Comorbidity Questionnaire (SACQ) comorbidity scale. Exploratory and confirmatory factor analyses were conducted. Reliability and internal consistency were measured by Cronbach's alpha. Validity was measured through correlation of the scales with the Self-Administered Comorbidity Questionnaire comorbidity scale and an analysis of the structural equations between them. Results: The scales showed adequate indicators based on the factor structure and showed Kaiser-Meyer-Olkin values above 0.90. After the exploratory factor analysis, all scales showed fit indicators suited to a factor model, following the same pattern as the original validations. Similarly, they showed good internal consistency (Cronbach's alpha greater than .78). The only scale that showed factor loadings suggesting the exclusion of any item was the Roland-Morris. In terms of validity, the scales showed positive correlation coefficients similar to the Self-Administered Comorbidity Questionnaire and between them. Conclusion: Regarding the scales evaluated, they showed similar indications of reliability and internal consistency, such that we did not find sufficient evidence to indicate one scale over another.
