The Occupational Depression Inventory (ODI) assesses work-attributed depressive symptoms. The ODI has demonstrated robust psychometric and structural properties. To date, the instrument has been validated in English, French, and Spanish. This study examined the psychometric and structural properties of the ODI's Brazilian-Portuguese version.
The study involved 1612 civil servants employed in Brazil (M = 44, SD = 9; 60% female). The study was conducted online across all Brazilian states.
Exploratory structural equation modeling (ESEM) bifactor analysis indicated that the ODI meets the requirements for essential unidimensionality. The general factor accounted for 91% of the common variance extracted. We found measurement invariance to hold across sexes and age groups. Consistent with these findings, the ODI showed strong scalability (H = 0.67). The instrument's total score accurately ranked respondents on the latent dimension underlying the measure. Furthermore, the ODI exhibited excellent total-score reliability (e.g., McDonald's ω = 0.93). Occupational depression correlated negatively with work engagement and each of its components (vigor, dedication, and absorption), speaking to the ODI's criterion validity. Finally, the ODI helped clarify the issue of burnout-depression overlap. Relying on ESEM confirmatory factor analysis (CFA), we found burnout's components to correlate more strongly with occupational depression than with each other. Using a higher-order ESEM-within-CFA framework, we found a correlation of 0.95 between burnout and occupational depression.
The ODI displays robust psychometric and structural properties within the Brazilian context. The ODI constitutes a valuable resource for occupational health specialists and may help advance research on job-related distress.
职业抑郁量表（ODI）用于评估工作所致的抑郁症状。ODI已展现出强大的心理测量和结构特性。迄今为止，该工具已在英语、法语和西班牙语版本中得到验证。本研究考察了ODI巴西葡萄牙语版本的心理测量和结构特性。
该研究纳入了1612名巴西公务员（M = 44，标准差 = 9；60%为女性）。研究在巴西所有州在线开展。
探索性结构方程模型（ESEM）双因素分析表明，ODI符合基本单维性的要求。一般因素解释了提取的共同方差的91%。我们发现测量不变性在性别和年龄组间成立。与这些发现一致，ODI显示出很强的可扩展性（H = 0.67）。该工具的总分在测量所基于的潜在维度上准确地对受访者进行了排名。此外，ODI表现出出色的总分信度（例如，麦克唐纳ω系数 = 0.93）。职业抑郁与工作投入及其各个组成部分（活力、奉献和专注）呈负相关，这表明了ODI的效标效度。最后，ODI有助于厘清倦怠与抑郁重叠的问题。基于ESEM验证性因素分析（CFA），我们发现倦怠的各个组成部分与职业抑郁的相关性比它们彼此之间的相关性更强。使用CFA框架内的高阶ESEM，我们发现倦怠与职业抑郁之间的相关性为0.95。
在巴西背景下，ODI展现出强大的心理测量和结构特性。ODI是职业健康专家的宝贵资源，可能有助于推进与工作相关困扰的研究。
