Further research to identify other items which are more suitable and specific to anxiety among Vietnamese adolescents may be helpful. Data Availability: All data files are available on Figshare (doi to be provided upon acceptance of the paper). As the DASS and DASS-21 were developed in Australia, their application among adolescents who live in other countries, speak different languages and have different cultures and context, requires careful consideration. Confirmatory factor analyses were performed to … Item loadings of those belonging to the DASS-21-A were not as good, especially for item 2 (dryness of the mouth) and item 9 (panic and make fool of self). Results from the principal factor analyses conducted separately for girls and boys revealed four factors in both groups (see Table 5), which indicated configurational invariance. It allows assessment of ten HRQoL domains, including physical, mental, general, social and perceived health and self-esteem, pain, disability, anxiety and depression [30]. 778 0 obj <>stream Factorial invariance between girls and boys was examined. Convergent validity was assessed through correlations of BASC-PRS scale scores with scale scores on the Child Behavior Checklist/4-18 (CBCL/4-18; Achenbach, 1991b). The results are robust with a systematically recruited, large sample, participants representing students from three main types of high schools and institutions in Vietnam, a high response rate and a low level of incomplete data. Convergent validity, along with discriminant validity, is a subtype of construct validity. Analyses of convergent validity included partial Pearson correlations between scores obtained on the four CogState tests and the four traditional neuropsychological tests selected a priori as conceptual matches, controlled for any demographic or health characteristics that were different between the control and patient groups. The DASS-21 in English and Vietnamese. These three factors were also allowed to correlate. Based on the observation from the 3F-model 1, where factor loadings were high, but there were very strong correlations between the three factors, we decided to examine a four-factor solution (4F-model 7) which had also been tested in Szábo’s study [15]. Symptoms of ‘dryness of the mouth’ or ‘feeling panic” and ‘making a fool of oneself’, however, may not represent symptoms of anxiety among this sample. These items were loaded primarily on the common General Distress factor. Copyright: © 2017 Le et al. The ADPH-V has been shown to have high internal consistency, acceptable reproducibility and confirmed construct validity [32]. The scale demonstrated adequate internal consistency (Cronbach α: 0.761 to 0.906). In this study, the factor structure and evidence about the convergent validity of the DASS-21 Vietnamese validated version among a large sample of Vietnamese adolescents is presented for the first time. struct validity by presenting correlations between a measure of a construct and a number of other measures that should, theoreti-cally, be associated with it (convergent validity) or vary indepen-dently of it (discriminant validity). S1 File. There were strong correlations between the three factors (standardised correlation coefficients between the DASS-21-D and DASS-21-A was 0.86; between the DASS-21-D and DASS-21-S 0.89 and between the DASS-21-A and DASS-21-S 0.93), suggesting indistinguishability of these factors.

Objectives To assess the internal consistency, latent structure and convergent validity of the Depression, Anxiety and Stress Scale-21 (DASS-21) among adolescents in Vietnam. endstream endobj startxref Models examined were based on the results from previous research about factor structures of the DASS-21 among adolescents [15,18,19,21,22,34]. The study shows the overall convergent validity of IPAQ within each PA category. Standardised scores, which allow comparison with the DASS, are presented in Table 3. The results may thus not be generalisable to out-of-school adolescents or those living in remote areas. doi: 10.1371/journal.pone.0180557. It is reported that mental disorders, including depression, are among the top 20 leading causes of disability worldwide [1]. Letters of approval were sought from the Heads of all schools and centres. Summary statistics for the DASS-21-V among 1,387 high school students in Vietnam. Convergent validity tests that constructs that are expected to be related are, in fact, related. Revision of items or even substitution of new items specific to these constructs among adolescents should be considered in such research. Students’ consent to participate was implied by their completion of the questionnaire. Summary statistics of the DASS-21-V for the whole sample, and separately for male and female students, are presented in Table 2. 24-31. This provides evidence that among these Vietnamese adolescents, symptoms of depression, which in this case, were characterised by items showing a lack of positive affect and loss of interest or pleasure, may be similar to those among adults and the use of the DASS-21 may be able to detect these. The DASS-21 is the shortened version of the DASS developed by Lovibond and Lovibond [5] to assess symptoms of depression, anxiety and stress among adults. For all other items, the loadings were very small and even negative (item 8 –using a lot of nervous energy). None of the schools and centres invited refused to participate. Students and their legal guardians received information packages about the study several days before the administration of the survey. Our results, however, were different from those reported in other research among Australian sample of children and adolescents [17–19] and Malaysian adolescents [21] who found one-factor, two-factor or three-factor structure models. Faculty of Social Sciences, Behaviours and Health Education, Hanoi School of Public Health, Hanoi, Vietnam, Affiliation: Convergence was not reached for this model. The DHP was adapted for use among adolescents [31] and this version of the DHP was validated for use among Vietnamese adolescents [32].
