Criteria for Detection of Possible Risk Factors for Mental Health Problems in Undergraduate University Students
Abstract
Introduction Developing approaches for early detection of possible risk clusters for mental health problems among undergraduate university students is warranted to reduce the duration of untreated illness (DUI). However, little is known about indicators of need for care by others. Herein, we aimed to clarify the specific value of study engagement and lifestyle habit variables in predicting potentially high-risk cluster of mental health problems among undergraduate university students. Methods This cross-sectional study used a web-based demographic questionnaire [the Utrecht Work Engagement Scale for Students (UWES-S-J)] as study engagement scale. Moreover, information regarding life habits such as sleep duration and meal frequency, along with mental health problems such as depression and fatigue were also collected. Students with both mental health problems were classified as high risk. Characteristics of students in the two groups were compared. Univariate logistic regression was performed to identify predictors of membership. Receiver Operating Characteristic (ROC) curve was used to clarify the specific values that differentiated the groups in terms of significant predictors in univariate logistic analysis. Cut-off point was calculated using Youden index. Statistical significance was set at p < 0.05. Results A total of 1,644 students were assessed, and 30.1% were classified as high-risk for mental health problems. Significant differences were found between the two groups in terms of sex, age, study engagement, weekday sleep duration, and meal frequency. In the ROC curve, students who had lower study engagement with UWES-S-J score < 37.5 points (sensitivity, 81.5%; specificity, 38.0%), <6 h sleep duration on weekdays (sensitivity, 82.0%; specificity, 24.0%), and < 2.5 times of meals per day (sensitivity, 73.3%; specificity, 35.8%), were more likely to be classified into the high-risk group for mental health problems. Conclusion Academic staff should detect students who meet these criteria at the earliest and provide mental health support to reduce DUI among undergraduate university students.
解説
大学生のメンタルヘルスの問題は、本人が不調に気づいて相談に来るまでに時間がかかることが多く、この未治療期間をいかに短くするかが課題になっています。ただ、周囲の教職員が「この学生は気にかけたほうがいい」と判断するための具体的な手がかりについては、これまであまり分かっていませんでした。
本研究は、学業へのエンゲージメントと生活習慣という、成績表や日常の様子から比較的つかみやすい変数に着目し、それらがメンタルヘルスの問題を抱えるリスクの高い群をどこまで予測できるかを調べたものです。Web 上の質問紙で、学生版のワーク・エンゲージメント尺度(UWES-S-J)に加えて睡眠時間や食事回数といった生活習慣を尋ね、抑うつと疲労の双方が認められる学生を高リスク群としました。
1,644人を対象とした横断調査の結果、30.1% が高リスク群に分類され、性別、年齢、学業エンゲージメント、平日の睡眠時間、食事回数の5項目で両群に有意な差が見られました。さらに ROC 曲線と Youden 指数によって境目となる値を求めたところ、UWES-S-J が 37.5 点未満、平日の睡眠時間が6時間未満、1日の食事が2.5回未満という条件に当てはまる学生は、高リスク群に分類されやすいことが分かりました。
いずれも感度は高い一方で特異度は低いため、これだけで判定するのではなく、早い段階で声をかけて支援につなげるための目安として使うことが想定されています。
