bookPart Instrumentos de mensuração em psiquiatria(2021) WANG, Yuan-Pang; HENNA, Elaine; JúNIOR, Antonio Reis de Sá; GORENSTEIN, Clarice- Response pattern of depressive symptoms among college students: What lies behind items of the Beck Depression Inventory-II ?(2018) SA JUNIOR, Antonio Reis de; ANDRADE, Arthur Guerra de; ANDRADE, Laura Helena; GORENSTEIN, Clarice; WANG, Yuan-PangBackground: This study examines the response pattern of depressive symptoms in a nationwide student sample, through item analyses of a rating scale by both classical test theory (CTT) and item response theory (IRT). Methods: The 21-item Beck Depression Inventory-II (BDI-II) was administered to 12,711 college students. First, the psychometric properties of the scale were described. Thereafter, the endorsement probability of depressive symptom in each scale item was analyzed through CTT and IRT. Graphical plots depicted the endorsement probability of scale items and intensity of depression. Three items of different difficulty level were compared through CTT and IRT approach. Results: Four in five students reported the presence of depressive symptoms. The BDI-II items presented good reliability and were distributed along the symptomatic continuum of depression. Similarly, in both CTT and IRT approaches, the item 'changes in sleep' was easily endorsed, 'loss of interest' moderately and 'suicidal thoughts' hardly. Graphical representation of BDI-II of both methods showed much equivalence in terms of item discrimination and item difficulty. The item characteristic curve of the IRT method provided informative evaluation of item performance. Limitation: The inventory was applied only in college students. Conclusion: Depressive symptoms were frequent psychopathological manifestations among college students. The performance of the BDI-II items indicated convergent results from both methods of analysis. While the CTT was easy to understand and to apply, the IRT was more complex to understand and to implement. Comprehensive assessment of the functioning of each BDI-II item might be helpful in efficient detection of depressive conditions in college students.
- Can Gender and Age Impact on Response Pattern of Depressive Symptoms Among College Students? A Differential Item Functioning Analysis(2019) SA JUNIOR, Antonio Reis de; LIEBEL, Graziela; ANDRADE, Arthur Guerra de; ANDRADE, Laura Helena; GORENSTEIN, Clarice; WANG, Yuan-PangBackground: Self-reported depressive complaints among college students might indicate different degrees of severity of depressive states. Through the framework of item response theory, we aim to describe the pattern of responses to items of the Beck Depression Inventory-II (BDI-II), in terms of endorsement probability and discrimination along the continuum of depression. Potential differential item functioning of the scale items of the BDI-11 is investigated, by gender and age, to compare across sub-groups of students. Methods: The 21-item BDI-II was cross-sectionally administered to a representative sample of 12,677 Brazilian college students. Reliability was evaluated based on Cronbach's alpha coefficient. Severity (b,) and discrimination (a) parameters of each BDI-II items were calculated through the graded response model. The influence of gender and age were tested for differential item functioning (DIF) within the item response theory-based approach. Results: The BDI-II presented good reliability (alpha = 0.91). Women and younger students significantly presented a higher likelihood of depression (cut-off > 13) than men and older counterparts. In general, participants endorsed more easily cognitive-somatic items than affective items of the scale. ""Guilty feelings,"" ""suicidal thoughts,"" and ""loss of interest in sex"" were the items that most likely indicated depression severity (b >= 3.60). However, all BDI-ll items showed moderate-to-high discrimination (a >= 1.32) for depressive state. While two items were flagged for DIF, ""crying"" and ""loss of interest in sex,"" respectively for gender and age, the global weight of these items on the total score was negligible. Conclusions: Although respondents' gender and age might present influence on response pattern of depressive symptoms, the measures of self-reported symptoms have not inflated severity scores. These findings provide further support to the validity of using BDI-II for assessing depression in academic contexts and highlight the value of considering gender- and age-related common symptoms of depression.
