青少年的睡眠健康與心理健康是廣受關注的公共衛生議題，本文試著從社會學的生命周期觀點來理解與分析。過去相關的研究，多是以橫斷面資料來討論兩者關係。即使是用長期資料分析的研究結果也大多不一致，多數都僅關注青少年期的短期影響，較少關注到生命週期中的長期影響變化。本文利用臺灣青少年成長歷程研究（TYP）的國一樣本，對從青少年期到成年早期共8波的長期追蹤資料進行分析。以生命歷程的視角，透過隨機截距交叉延宕模型（RI-CLPM），分離個體間與個體內的影響，藉此釐清在個體內隨時間變動下，睡眠問題、正面情緒與負面情緒的長期關係。
分析結果顯示，在個體間層次上，睡眠問題、正面情緒與負面情緒存在穩定的關聯。在個體內層次上，個人的睡眠問題與負面情緒都具有顯著的穩定延續效果。不過此效果在青少年到成年早期的過渡階段減弱消失。正面情緒則僅在青少年早期具有顯著的穩定延續效果。從交叉延宕效果上發現，睡眠問題與情緒的長期關係傾向於「睡眠問題影響情緒」主導的影響關係。但兩者的長期關係也會受到「生命週期壓力」影響，因特定生命階段情境（如升學階段或青少年到成年早期的過渡階段）而異，出現「情緒影響睡眠問題」的影響關係。此外這些影響主要由睡眠問題與負面情緒所驅動，而非正面情緒。
論文外文摘要： In recent years, sleep health and mental health have become widely discussed topics and are regarded as important public health issues. This study takes a sociological approach by examining their associations across from the adolescence to early adulthood. Past research on the relationship between sleep problems and emotions has predominantly relied on cross-sectional data, limiting the understanding of their long-term dynamics. Even studies utilizing longitudinal data often yield inconsistent results, with most focusing solely on the short-term effects during adolescence, while neglecting the long-term changes across the life cycle. This study analyzes eight waves of longitudinal data from the Taiwan Youth Project, covering the period from adolescence to early adulthood. By adopting a life course perspective and employing a random intercept cross-lagged panel model (RI-CLPM), we distinguish between interindividual and intraindividual effects to elucidate the long-term relationships between sleep problems, positive affect, and negative affect as they evolve over time.
The results indicate that, at the between-person level, there are stable associations between sleep problems, positive affect, and negative affect. At the within-person level, sleep problems and negative affect exhibit significant stable continuity, although this effect weakens and eventually disappears during the transition from adolescence to early adulthood. Positive affect, on the other hand, demonstrates significant stable continuity only during early adolescence. The cross-lagged effects reveal that the long-term relationship between sleep problems and emotions tends to be predominantly driven by "sleep problems affecting emotions." However, these long-term relationships are also influenced by "life cycle stress" where specific life stages or contexts (such as during academic transitions or the transition from adolescence to early adulthood) can lead to a shift in the relationship, with "emotions affecting sleep problems." Additionally, these effects are primarily driven by sleep problems and negative affect, rather than positive affect.
