RESUMO
ABSTRACT Objective: This study investigates the psychological impacts and their associated factors on patients with COVID-19 at a Thai field hospital. Methods: All eligible patients confirmed to have COVID-19 at Thammasat University field hospital completed an online self-reported mental health screening questionnaire which collected sociodemographic data, their clinical characteristics, and used the depression, anxiety, and stress scale (DASS-21). Results: A total of 40 patients participated in the study. The depression rate was found to be 22.5%, while the anxiety rate was 30%, and the stress rate was 20%. Having a history of psychiatric disorder alone was significantly associated with a higher DASS-21 score (p = 0.001). Meanwhile, gender, age, level of education, occupation, living status, severity of COVID-19, and the number of days admitted to hospital prior to the field hospital were not found to be associated with the DASS-21 scores (P > 0.05). Conclusion: The depression, anxiety, and stress symptoms in patients with COVID-19 at the field hospital were common. Patients with a history of psychiatric disorder should undergo specific evaluation during the isolation phase.
RESUMO
Abstract Objective To assess the psychometric properties of the Thai version of the Scale for the Assessment of Positive Symptoms (SAPS-Thai). Methods Content validity was evaluated by four psychiatrists who rated the SAPS-Thai, and the content validity indexes (CVI) were also analyzed. Known-group validity was assessed by comparing the SAPS-Thai score among thirty outpatients and ten inpatients with schizophrenia. Internal consistency was calculated using the Cronbach's coefficient alpha. Results SAPS-Thai has excellent content validity, with an average-CVI of 0.92. The inpatient group had a significant higher score for both the global SAPS-Thai scores [7.4 (1.95) vs. 1.93 (1.59), p < 0.001] and total SAPS-Thai scores [21.2 (11.8) vs. 3.67 (2.87), p < 0.001] indicating good known-group validity. SAPS-Thai had a good internal consistency with a Cronbach's alpha of 0.87. Discussion SAPS-Thai provides a comprehensive measurement of positive symptoms and indicated content and known-group validity and a satisfactory level of internal consistency reliability.
