RESUMEN
The Thai Mental Health Questionnaire (TMHQ) has been developed for assessing the effectiveness of mental health services. The purpose of this study was to investigate the validity and reliability of the TMHQ in patients in contact with mental services. Subjects (age 12-74) came from out-patient and acute in-patient units in general practice. We obtained the opinions of experienced professionals, advocacy groups and patient groups to evaluate consensual and content validity. The results of this study showed that 1,205 patients were assessed using the TMHQ scale. Test-retest, Odd-even, and Cronbach's Alpha reliability were good for some items and poor for others. The TMHQ had good criterion validity: acute in-patients had higher scores than out-patients. TMHQ also had good concurrent validity, correlating well with other scales. Comments suggested the TMHQ was a useful and suitable scale for this population although social factors were not sufficiently covered.
RESUMEN
The purpose of this study was to develop the Thai Mental Health Questionnaire, having sufficient discriminate power, adequate construct validity, and reliability. The subject were two groups; (1) pilot study samples: 60 samples and (2) survey samples were 700 samples consisted of normals, psychiatric outpatients, and psychiatric inpatients. Data collected from the Thai Mental health Questionnaire was developed from criteria based on the DSM-IV. The results of this study showed that the final test composed of 70 items - was found to be significantly different at the .001 level between those people with mental disorders and normal people. The construct validity of this test consists of five factors: somatic, depression, anxiety, psychotic, and social function. The reliability coefficients for the Alpha were range from 0.82 to 0.94.
