“…This is a 7-item instrument investigating anxiety disorders over the past two weeks using the DSM-IV criteria as “0” (not at all) to “3” (nearly every day). GAD-7 presents excellent reliability among Brazilian adults (α = 0.916) 56 . Optimism using the Life Orientation Test-Revised (LOT-R) 41 , validated for the Brazilian population 57 .…”

The present study aims to investigate how different levels of spirituality and religiousness (high spirituality and high religiousness –S/R, high spirituality and low religiousness –S/r, low spirituality and high religiousness s/R and low spirituality and low religiousness – s/r) are associated with quality of life, depressive symptoms, anxiety, optimism and happiness among adults. A cross-sectional study was carried out among 1,046 Brazilian adults. Concerning the different levels of spirituality and religiousness, 49.2% had s/r, 26.5% S/R, 17.2% S/r and 7.1% s/R. Participants with S/R had better outcomes as compared to those with s/r and those with S/r in WHOQOL Psychological, Social Relationship and Environment, Optimism and happiness. Participants with s/R had better outcomes as compared to those with s/r in WHOQOL Psychological and Social Relationship, Optimism and happiness. Participants with S/r were different from those with s/r, with higher levels of WHOQOL Environment and happiness but also anxiety. The results revealed that, having higher levels of both spirituality and religiousness were more correlated to better outcomes than having just one of them or none of them. Likewise, having higher levels of religiousness in detriment of higher levels of spirituality was also associated with better outcomes in comparison to others.

The DSM-5 highlights the use of dimensional assessments of mental health as a supplement to categorical diagnoses. This study investigated the psychometric properties of the DSM-5 Dimensional Anxiety Scales in a Brazilian community sample. Dimensional scales for generalized anxiety disorder, social anxiety disorder, panic disorder, agoraphobia, and specific phobia were administered to 930 adults aged 18 to 70, 64.2% female. Psychometric properties investigated were: unidimensionality; measurement invariance; internal consistency; composite reliability; test-retest reliability; convergent and divergent validity; category thresholds and item performance analyses. Analyses revealed unidimensionality for all scales except for specific phobia. Measurement invariance, high internal consistency and composite reliability, and convergent and divergent validity were demonstrated. Test-retest reliability was high for all scales but generalized anxiety disorder. Item-based analyses evidenced that none of the items were very easy to endorse and that the scales offered more information about subjects with high severity estimates of anxiety. The DSM-5 Dimensional Anxiety Scales are a valid and reliable alternative to assess anxiety symptomatology in community settings, although further evaluation is needed, especially for specific phobia. The scales seem to be more useful for characterizing dimensionality of symptoms for subclinical or clinical cases than for slight or mildly anxious subjects.

“…As a short and objective self-report measure showing strong properties as a screening tool 11 , researchers have tested its psychometric characteristics in several settings. In this context, over the last decade, GAD-7 has been presented as a reliable and valid questionnaire in different languages 14,15,16,17,18 including Portuguese 19 , with heterogeneous psychiatric samples 20,21 for specific medical conditions 22,23,24,25 in the general population 26 and in geriatric samples 27 . However, the one-dimensional nature of GAD-7 proposed by the original model is not consistent in the literature.…”
