The aim of the present study was to validate the Korean American Parental Depression Literacy Scale (Parental D-Lit Scale), which was modified from Griffith's Depression Literacy Scale based on expert reviews, individual and focus group interviews, and a cross-sectional, self-administered survey. Survey participants included Korean American mothers (n = 107, 74.8%) and fathers (n = 36, 25.2%) of adolescent children. We examined reliability and validity using exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and correlational and comparison analyses. The scale showed moderate reliability and validity (α = 0.72) and content validity (scale-level content validity index = 0.875). EFA resulted in a three-factor model, and CFA showed a close fit to the data (root mean square error of approximation = 0.056). Reliability indices indicated that total scale scores were more useful for examining depression literacy than subscale scores. Criterion validity was supported by statistically-significant correlations in the expected direction between depression literacy and other theoretically-related constructs, including attitudes towards mental health-care services (+), depression stigma (-), recognition of depression (+), and acculturation (+). The Parental D-Lit Scale scores showed statistically-significant mean differences between parents who identified depression in a vignette (mean = 18.3, standard deviation (SD) = 2.9) and those who did not (mean = 16.8, SD = 4.0), indicating the discriminant validity of the scale. The Parental D-Lit Scale shows promise for use by psychiatric/mental health nurses in assessing the effectiveness of educational and clinical interventions. Additional research should employ larger samples in various regions of the USA.
本研究旨在验证韩国美国家长抑郁知识量表（Parental D-Lit Scale），该量表基于专家评审、个体和焦点小组访谈以及横断面、自我管理调查，对 Griffith 的抑郁知识量表进行了修改。调查参与者包括青少年子女的美国家长（母亲：n=107，74.8%；父亲：n=36，25.2%）。我们采用探索性因子分析（EFA）、验证性因子分析（CFA）以及相关和比较分析来评估信度和效度。该量表显示出中等的信度和效度（α=0.72）和内容效度（量表水平内容效度指数=0.875）。EFA 得出了一个三因素模型，CFA 显示数据拟合良好（近似均方根误差=0.056）。信度指标表明，与子量表分数相比，总量表分数更有助于评估抑郁知识。在与其他理论相关的结构（包括对心理健康服务的态度（+）、抑郁污名（-）、对抑郁的识别（+）和文化适应（+））呈预期方向的统计学显著相关，支持了效标效度。在识别案例中抑郁的父母（平均 18.3，标准差（SD）=2.9）和未识别的父母（平均 16.8，SD=4.0）之间，Parental D-Lit Scale 得分存在统计学显著的均值差异，表明该量表具有判别效度。Parental D-Lit Scale 有望为精神科/心理健康护士评估教育和临床干预的效果提供帮助。进一步的研究应该在美国的不同地区使用更大的样本。
