研究目的：失眠為國人常見的健康問題，造成患者夜間睡眠的痛苦，對白天生活品質也有明顯的影響，站在預防失眠慢性化的角度切入，找出情境性失眠高危險群的心理病理特性，應可為防治失眠疾患提供更積極的建議。本研究目的一即是想透過與好眠組的比較，討論壓力因應風格、持續失眠相關病因(對睡眠不適當認知、睡眠相關安全行為、身心激發程度)在失眠高危險族群及慢性失眠者的特性為何。第二個目的則想驗證失眠持續因素對失眠的影響路徑，並探討壓力因應風格在失眠持續模式中的影響性為何。 研究方法：本研究以橫斷式問卷調查法收集資料，蒐集有效問卷情境性失眠高風險群組74份、好眠組75份、與慢性失眠組62份，總共211份有效問卷。統計方法則根據不同研究目的分別採用單因子變異數分析及結構方程模型的路徑分析進行資料處理。 研究結果：慢性失眠者比好眠者與慢性失眠者有更高的睡眠不適當認知、更多睡眠相關安全行為更高的睡前激發程度。慢性失眠者與情境性失眠高危險族群在面對壓力時，也比好眠者使用較多的「社會支持、情緒調節與發洩的調解」、「逃避」、「問題解決、重釋與接受」等因應策略。此外，情境性失眠高危險族群也比好眠者用更多的睡眠相關安全行為來因應疲憊或睡不好的狀況。另外，本研究路徑分析結果發現睡眠不適當認知會透過安全行為及激發程度而影響失眠，且在考驗各個壓力因應風格對失眠持續模式之影響時，發現較一致的結果是逃避因應可能會增加個體使用更多睡眠相關安全行為而惡化失眠 研究討論：研究結果支持過去理論認為睡眠不適當認知、睡眠相關安全行為及睡前激發程度為失眠的持續因子。為預防情境性失眠高危險族群其失眠症狀慢性化，建議重點應放在睡眠的衛生教育，並且不只是教導適當因應失眠的行為，重要的是需包括增強對失眠處理的控制感、建立適當合理的藥物使用概念、矯正對失眠後果的災難化想法。最後，過去少有其他研究討論逃避因應風格與失眠的關係，建議對此有興趣的研究者可對逃避因應風格與失眠的關係做進一步的重覆驗證與探討。 / OBJECTIVE: The goals of the study are to examine (1) the differences of coping, dysfunctional beliefs and attitudes about sleep, sleep related safety behaviors and pre-sleep arousals among chronic insomniacs, normal sleepers vulnerable to stress-related sleep disturbance and good sleepers (2) the interactions of coping with other etiological factors in the model of persistent insomnia. METHOD: The sample was composed of 211 participants. Participants were asked to complete a set of questionnaires, including the Ford Insomnia Response to Stress Test (FIRST), the Insomnia Severity Index, the Pre-Sleep Arousal Scale, the Sleep-Related Behaviour Questionnaire, the Dysfunctional beliefs and attitudes about sleep questionnaire, COPE, the Center for Epidemiologic Studies Depression Scale, the Beck Anxiety Inventory and the Pittsburgh Sleep Quality Inventory. The participants were categorized into three subgroups, 75 good sleepers, 74 normal sleepers vulnerable to stress-related sleep disturbance, and 62 chronic insomniacs, according to clinical interview and/or their scores on the FIRST. RESULT: The results showed that chronic insomniacs reported more dysfunctional beliefs and attitudes about sleep, sleep related safety behaviors and pre-sleep arousals than the other groups. In addition, chronic insomniacs and normal sleepers vulnerable to stress-related sleep disturbance used more coping styles of “problem solving, positive reinterpretation and acceptance”, “social support, focus on and venting of emotions”, and “avoidance” than good sleepers. Also, normal sleepers vulnerable to stress-related sleep disturbance reported more safety behaviors to cope insomnia than good sleepers. Furthermore, the path analysis showed that the safety behaviors and arousal play an important mediating role between dysfunctional beliefs and attitudes about sleep and insomnia in chronic insomniacs. Finally, data showed that avoidance coping could predict the frequency of sleep related safety behaviors. CONCLUSION: The results imply that in order to prevent normal sleepers vulnerable to stress-related sleep disturbance from becoming chronic insomniacs, sleep hygiene education program should incorporate methods that are designed to reduce maladaptive sleep beliefs and sleep related safety behaviors. The relationship found between avoidance coping and insomnia is also of interest and require replication in future researches.

緒論 失眠困擾對身心健康有重大的影響，除了藥物取向的治療外，失眠認知行為治療（CBT-I）有足夠的實證研究證據肯定其療效，由於在認知行為治療（CBT）的研究中有證據支持參與者在家中，對治療技術練習與執行的程度與療效有關，因此CBT-I的療效可能也與患者對治療技術的執行程度有關，過去雖然也有少數研究探討CBT-I執行程度與療效的關係，但這些研究缺乏針對CBT-I各個治療技術的執行程度評估，因此本研究欲探討CBT-I中，各項治療技術（睡眠衛生教育、放鬆訓練、刺激控制法、睡眠限制法，及認知重建）的執行程度及執行規律程度，與特定療效指標改善程度的關係。 方法 研究參與者含原發性失眠患者22位，共病其它疾患的失眠患者16位，經篩選階段確認符合收案條件後，在接受為期七週的CBT-I團體治療期間，於第二週起需每日填寫執行程度問卷，同時帶領團體的治療師也於治療第三週起，以治療師執行程度評估量表來評估參與者的執行程度。參與者在治療前後另需分別填寫一週睡眠日誌以及睡眠困擾問卷（Insomnia Severity Inventory；ISI），以睡眠日誌中的SOL、WASO、TST、SE，及ISI得分的前後測改變分數，作為代表療效指標之依變項，預測變項則為參與者自評及治療師所評估的各項治療技術之執行程度分數，治療技術包括：睡眠衛生、放鬆訓練、刺激控制法、睡眠限制法，以及認知重建；並分別以平均數代表執行程度，而以變異數代表執行期間的規律程度。 結果 資料分析以皮爾森相關分析檢驗執行程度與療效間的關聯性，在全部樣本中的結果發現，參與者自評對認知重建的平均數與WASO的改善程度有正相關，以及治療師評估CBT-I的平均數與SOL的改善程度有正相關；而參與者自評放鬆訓練的平均數越低、刺激控制法變異數越高，則ISI的改善程度越好，為不符合預期的結果。在原發性失眠組中發現治療師評估睡眠衛生的平均數與WASO的改善有正相關，治療師評估睡眠限制法的平均數與SOL、TST，以及SE的改善有正相關，而變異數與SOL的改善有負相關，以及治療師評估CBT-I的平均數與SOL的改善有正相關；而不符合預期的結果為，參與者自評執行刺激控制法的變異數與ISI的改善有正相關。最後，在共病組中並沒有發現執行程度與療效之間有顯著相關的結果，而放鬆訓練以及刺激控制法兩項治療技術，也沒有與療效指標有符合預期的顯著相關結果。 結論 對於共病失眠患者而言，治療技術的執行評估與療效間未反映出顯著相關，可能因受限於睡眠生理疾患的干擾，使得療效未如原發性失眠組明顯；而就原發性失眠組而言，睡眠限制法的執行程度是與較多療效指標達到顯著相關的治療技術，顯示睡眠限制法的執行對於改善睡眠症狀有所幫助。本研究較為重大的限制在於，治療技術執行程度評估的評分者間一致性有限，後續研究可進一步發展評估執行程度更適當的方法。 / Introduction Insomnia is a common problem that has a significant impact on patients' physical and mental health. In addition to pharmacological therapy, there are sufficient empirical data to support treatment efficacy of cognitive behavioral therapy for insomnia (CBT-I). A major part of cognitive behavioral therapy is to teach the patients to learn specific cognitive and behavioral techniques that requires to be practiced at home by the patients. Previous studies have reported an association between the degree of adherence to treatment techniques and treatment effects in cognitive behavioral therapy for disorders other than insomnia. Some studies further explored the relationship between treatment adherence and treatment outcome in CBT-I. However, none of the study looked into the adherence to different treatment components on different aspects of treatment outcome. The aim of this study therefore is to explore the relationship between the adherence to different treatment components in CBT-I and the improvement in different sleep parameters. Method Twenty-two patients with primary insomnia and sixteen patients with comorbid insomnia were recruited for this study. During the 6-week period of treatment with CBT-I, they completed a treatment adherence questionnaire daily. The therapists also evaluated the patients’ adherence weekly after treatment sessions. They were required to keep sleep diaries from one week before to one week after the end of the 6-week CBT-I program. They also completed the ISI and sleep diary for one week before and after the treatment. The treatment outcome variables included the ISI score, and sleep onset latency (SOL), wake after sleep onset (WASO), total sleep time (TST) and the sleep efficiency (SE) from sleep diaries. The treatment components evaluated included sleep hygiene, relaxation, stimulus control, sleep restriction and cognitive reconstruction. The predictive variables included the mean for the adherence degrees and the variance for the adherence regularity of the adherence score evaluated by the participants and therapists. Results Pearson correlation was used to examine the associations between the adherence to respective treatment components in CBT-I and the variables of treatment outcome. In the whole sample, the decrease of the WASO correlated significantly with adherence to cognitive reconstruction evaluated by the patients, and the decrease of the SOL correlated significantly with adherence to CBT-I evaluated by the therapists. Nonetheless, the lower adherence to relaxation and the higher variance of adherence to stimulus control, the more improvement of the ISI. In patients with primary insomnia, the decrease of WASO correlated significantly with adherence to sleep hygiene evaluated by the therapists; the decrease of SOL and the increase of TST and SE showed significant correlation with adherence to sleep restriction evaluated by the therapists; the decrease of SOL showed significant negative correlation with the variance of adherence to sleep restriction evaluated by the therapists; the decrease of SOL showed significant positive correlation with the adherence to CBT-I evaluated by the therapists. Opposite to expectation, the decrease of the ISI score correlated significantly with variability of adherence to stimulus control evaluated by the patients. Finally, in patients with comorbid insomnia, the treatment component adherence did not correlate significantly with any outcome variables. The adherence of relaxation and stimulus control did not show significant correlation with outcome variables. Conclusion In patients with comorbid insomnia, treatment effects were not associated with adherence. This may due to the multifactorial nature of comorbid insomnia. Among the treatment components, adherence to sleep restriction seems to be the most predictive factor for good treatment outcome in primary insomnia. One limitation of the present study is its low inter-rater reliability of treatment components adherence evaluation. Therefore, more appropriate methods need to be developed to evaluate the adherence of treatment techniques.

研究目的 失眠的過度激發是目前最廣為接受的失眠病因之一。無論在生理、認知、行為三不同層面上，多可觀察到失眠者有身心過度激發的狀態。根據失眠三因子模式，不同失眠病程階段，影響過度激發的背後成因有所差異。在慢性失眠部分，過 去累積了相當多的實證研究證實其過度激發的現象，但尚未進入慢性病程前之過度激發相關機轉，仍有待研究進一步探討。本研究嘗試以橫斷式的研究方法，並依據過去失眠病因發展推導，選擇從壓力反應特性 (包含壓力操弄後的壓力反應強度和 消退速度)、注意力偏誤 (包含警覺性注意力和注意力移除困難)、與睡前的睡眠監控行為三個面向切入，探討不同病程階段個體過度激發的背後機轉，並進一步檢驗上述之差異是否可用以預測在壓力操弄情境下，不同病程個體睡前的激發反應變化，藉此檢驗失眠病程發展之病因假說，並希望未來可據此發展有效之失眠防治與介入策略。 研究方法 本研究共計招募受試者 58 人，年齡介於 24-48 歲，包含符合 ICSD-3 慢性失眠者 18 人，以及以壓力下失眠反應量表( Ford Insomnia Response to Stress Test; FIRST)區分出急性失眠高危險組 19 人與低危險組 21 人。每位受試者皆需到睡眠實驗室進行兩階段的實驗，第一階段包含晤談評估、問卷填答、壓力反應的生理測量(以指溫與膚電為指標)、與包含威脅與睡眠刺激之點偵測注意力作業，之後需配戴腕錶與記錄睡眠日誌配合充足且規律作息一週後，再到睡眠實驗室進行第二階段的評量，包含睡前 2 小時、1 小時、關燈前生理指標 (指溫、膚電) 與腦波的測量和主觀身心激發狀態 (Pre-Sleep Arousal Scale, 簡稱 PSAS) 評量，於睡前填寫睡眠相關監測指標 (Sleep Associated Monitoring Index，簡稱 SAMI)，並完成一晚的 PSG 測量以排除其他睡眠相關疾患。 研究結果 首先，以單因子變異數分析比較不同組別間在壓力反應與回復和二因子變異數分析注意力警覺/移除困難指標的差異。在壓力生理反應表現上，慢性失眠組與高危險組在接受壓力操弄後的激發消退時間較低危險組來得長。在注意力層面，高危險組對壓力(威脅圖片) 刺激有顯著的警覺與移除困難注意力偏誤，慢性失眠組則是對睡眠刺激有顯著的移除困難注意力偏誤。在行為層面，慢性失眠組與高危險組睡前的注意力監控行為 (包含監測自身身體感覺訊息是否與入睡狀態不一致、鬧鐘 時間、環境) 均顯著較低危險組來得多。再者，以皮爾森相關探討注意力偏誤與睡前激發反應之關聯性，結果顯示高危險組的注意力偏誤現象與睡前高頻腦波與主觀生理激發的降幅呈現顯著負相關; 而慢性失眠組的注意力偏誤指標卻與膚電、主觀認知激發的降幅呈顯著正相關。 結論 本研究結果支持不同失眠病程背後的過度激發影響機制有所差異，生理層面較慢的激發消退能力與對壓力源的認知偏誤的前置因子，可能為急性失眠者易受日常壓力源誘發睡眠困擾之原因；而影響慢性失眠族群的持續因子主要在於其將睡眠視 為壓力源的認知歷程與行為轉變。此外，研究更進一步發現兩組分別對於壓力與睡眠的注意力轉移困難，使其在覺察壓力後易持續表現出過度激發現象。本研究結果除支持失眠過度激發理論之外，更釐清不同階段失眠的認知歷程的機制，並彰顯不 同失眠病程介入策略應有所差異，和急性失眠高危險族群及早介入預防之重要性。 / Introduction Hyperarousal has been recognized to be a major etiological factor of chronic insomnia. Cumulated research evidences have demonstrated that chronic insomnia patients are hyperaroused in somatic, cognitive, and behavioral aspects. According to Spielman’s 3P Model of Insomnia, there were different factors are involved at different points during the course of insomnia. However, there are seldom study to investigate the difference mechanism of hyperarousal in the course of the development of insomnia. The present study used cross-sectional design to compare the difference of good sleeper (low sleep vulnerability, LV), acute insomnia (high sleep vulnerability, HV), and chronic insomnia (CI) in stress reaction (eg. reactivity and recovery), attentional bias (eg. vigilance and disengagement), and sleep associated monitoring behaviors to investigate the underlying mechanism of hyperarousal. Furthermore, the study examined the correlation between attentional bias indices and subsequent pre-sleep arousal to investigate the impact of attentional bias on sleep in different groups. Method The present study recruited fifty-eight subjects, aged between 24-48. They included eighteen chronic insomniacs (CI) diagnosed ICSD-3, nineteen healthy individuals scoring high (HV) and twenty-one healthy individuals scoring low (LV) on the Ford Insomnia Response to Stress Test (FIRST). All subjects visited sleep lab twice. During the first visit, the subjects filled in a package of questionnaires, and went through psychophysiological recording (including) of stress reaction, and a visual dot-probe task. They then were required to keep a sleep log and wear actigraphy at home for one-week to make sure they followed a regular sleep schedule. During the second visit, subjects went through a pre-sleep physiological recording (including peripheral temperature, skin conductance, and EEG) and filled in two questionnaires (Pre Sleep Arousal Scale [PSAS] and Sleep Associated Monitoring Index[SAMI]) at three time points and had a PSG recording to screen for sleep disorders. Result One-way ANOVAs were conducted to compare the differences of stress reaction/recovery among three groups. Two-way ANOVAs were used to compare the differences in attentional bias (vigilance/ disengagement) of threatening and sleep-related stimulus among three groups. In stress related physiological activity, CI and HV showed slower recovery rate than LV. Considering attentional bias, HV had significant vigilance and disengagement bias to threatening pictures, and CI had significant disengagement bias to sleep-related pictures. CI and HV also showed more prevalent sleep-associated monitoring behaviors than LV. Furthermore, Spearman’s correlation was used to examine the association between attentional bias and pre-sleep arousal. The result shows the attentional bias of HV had negative correlation with reduction of high frequency EEG and somatic sub-score on the PSAS. In contrast to our prediction, CI showed positive correlation between decrease of skin conductance and the cognitive sub-score on the PSAS. Conclusion The study showed that stress recovery ability and stress-related attentional bias were the major differences between individuals with low and high sleep vulnerability, indicating that increased information processing to threats and stress-related stimulus as well as decreased recovery ability of autonomic arousal in reacting to stress may predisposed an individual to stress-related sleep disturbances. On the other hand, the attention shift from threat toward sleep can differentiate chronic insomnia from those individual with frequent acute insomnia. Moreover, the difficulty in disengagement from sleep-related stimulus, rather the vigilance, might explain the cause of hyperarousal that perpetuate insomnia. The results support the transition of arousal from general treat to sleep-related stimulus in the development of chronic insomnia. The study not only further the understanding of the etiological mechanism of insomnia, but also imply that different strategies should be applied in the treatment of acute and chronic insomnia. It also highlights the importance of preventive intervention for individuals with high sleep vulnerability

研究目的 對於慢性腎臟病患者而言，睡眠困擾是十分常見的問題。過去相關研究中，研究對象較偏重於已進入透析治療的患者，且大多著重於探討人口學及臨床變項，而忽略了心理及行為因素（例如睡前激發狀態、睡眠衛生行為）的影響。本研究試圖改善過去研究之不足，釐清心理及行為因子在慢性腎臟病患者的睡眠問題中所扮演之角色。 研究方法 本研究採橫斷性調查研究，於腎臟科門診及血液透析室招募第三期到第五期（eGFR＜60 ml/min/1.73m2）的慢性腎臟病患者。最終納入分析的個案共有152人，其中77人為未達尿毒症的慢性腎臟病患者，75人為穩定接受血液透析治療（3個月以上）的尿毒症患者。受試者需完成匹茲堡睡眠品質量表、失眠嚴重度量表、睡眠衛生行為量表、睡前激發狀態量表、醫院焦慮與憂鬱量表，並且回答和不寧腿症候群、疼痛及皮膚癢程度相關的問題，此外，本研究亦從病歷紀錄中抄錄相關的檢驗數値以及共病情形。 研究結果 未透析患者約有29.9%睡眠品質不佳、23.4%有失眠問題；而血液透析患者約有57.3%睡眠品質不佳、28.0%有失眠的問題。血液透析患者和未透析患者相比，其睡眠品質顯著較差，且失眠較為嚴重。迴歸分析結果顯示，MMSE得分較低、共病較多、疼痛程度較高、和焦慮相關行為較多可預測較差的睡眠品質，而焦慮與憂鬱情緒較高、焦慮相關行為較多、和認知激發程度較高可預測較嚴重的失眠。未透析患者的睡眠問題主要是受到和激發相關的行為或認知活動的影響，而血液透析患者的睡眠則較容易受到疾病和症狀相關因素的影響。 結論 疾病與臨床因素、身體症狀、以及睡眠心理及行為相關因素對於慢性腎臟病患者的睡眠有所影響，但對於未透析和已透析的患者，其影響因素和影響程度可能不同。

研究背景與目的：2008年美國睡眠醫學會(American Academy of Sleep Medicine)對於失眠患者在助眠劑的臨床使用原則中(clinical guideline)，建議初次藥物治療的時間以2至4週較為適宜，後續是否繼續用藥則須專業醫師的重新評估，以降低身體對於藥物的依賴性及副作用的風險，但實際上許多失眠患者因擔心停用助眠劑就無法入眠，因此仍長期使用助眠劑。目前臨床上大都採用逐步減藥的方式協助患者降低助眠劑的使用，除了藥物因素會影響減藥成效之外，從心理因素來看，在過去研究指出自我效能會影響健康行為的改變，因此本研究將比較逐步減藥計畫加上提升減藥自我效能策略與單獨逐步減藥計畫對於原發性失眠患者在減藥上的成效。 研究方法：本研究的原發型失眠患者共48人(男17人，女31人，平均年齡46.8歲，平均使用助眠劑66.7個月)，被分為兩組進行10週的減藥介入計畫，一組為自我效能提升組(n=24)，受試者減藥前先接受為期兩週的提升減藥自我效能策略，再進行8週的逐步減藥計畫，另一組為單純減藥組(n=24)，受試者只進行8週的逐步減藥計畫。受試者每週均需填寫睡眠日誌、單題減藥自我效能量尺，以瞭解睡眠參數、減藥自我效能及助眠劑使用之情況。 研究結果：減藥成效方面，自我效能提升組在減少劑量的百分比顯著高於單純減藥組(自我效能提升組=78.62%；單純減藥組=64.10%)，且自我效能提升組在減藥前後劑量的改變也顯著高於單純減藥組(自我效能提升組=4.35顆/週；單純減藥組=3.22顆/週)，自我效能提升組在停藥人數的百分比上雖未顯著高於單純停藥組(自我效能提升組=29.2%；單純減藥組=16.7%)，但就整體結果來看均較為支持自我效能提升組在減藥的成效上是優於單純減藥組。減藥自我效能方面，在控制住第1週的減藥自我效能後，提升減藥自我效能策略造成的減藥自我效能改變量仍可以有效解釋21.9%的減藥百分比。 研究結論：自我效能提升組增加的提升減藥自我效能策略能有助於個案在執行逐步減藥計畫的成效，另外，提升減藥自我效能策略造成的減藥自我效能改變量是減藥百分比有效的預測因子。因此，減藥自我效能對於減藥成效來說，確實是一個可以著力的部分。 / Introduction：According to the 2008 clinical guidelines for insomnia by the American Academy of Sleep Medicine proposed, hypnotic use is recommended for short-term use for 2 to 4 weeks. However, many insomnia patients have difficulty to stop hypnotic use. In clinic practices, gradual tapering is usually applied in helping patients to reduce the hypnotic use. Previous studies have shown that self-efficacy of the patients are associated with medication tapering. The present study examine the effect of the institution of a self-efficacy enhancement strategy prior to gradual tapering plan on hypnotic tapering in patients with primary insomnia. Methods：Forty-eight patients with primary insomnia (17 men, 31 women；mean age of 46.8 years；mean duration of hypnotics use of 66.7 months) were assigned to two groups: a self-efficacy enhancement group and a tapering group. Patients in the self-efficacy enhancement group (n=24) underwent a two-week self-efficacy enhancement strategy prior to an eight-week gradual tapering plan. Patients in the tapering group (n=24) participated in the eight-week gradual tapering plan only. The main outcome measures were sleep parameters from sleep diary, a single-item tapering self-efficacy rating scale, number of pills taken per week, and percentage of dosage reduction. Results：The percentage of dosage reduction of patients in the self-efficacy enhancement group was significantly more than those in the tapering group (the self-efficacy enhancement group = 78.62%；the tapering group = 64.10%). The number of pills taken per week also showed significantly more reduction for patients in the self-efficacy enhancement group than those in the tapering group (the self-efficacy enhancement group = 4.35 pills per week；the tapering group = 3.22 pills per week). However, the percentage of drug-free patients at the end of the programs in the self-efficacy enhancement group was not significant different from those in the tapering group (the self-efficacy enhancement group = 29.2%；the tapering group = 16.7%). Overall, the effect of hypnotic tapering in the self-efficacy enhancement group was better than those in the tapering group. In addition, linear regression showed that the tapering self-efficacy data showed that, after controlling baseline tapering self-efficacy, the change of tapering self-efficacy following the first two weeks of self-efficacy enhancement strategy can explain the variation of percentage of dosage reduction up to 21.9%. Conclusions：The institution of self-efficacy enhancement strategy can increase the efficacy of gradual tapering plan for hypnotics. In addition, the level of tapering self-efficacy enhanced by the self-efficacy enhancement strategy is a good predictor for dosage reduction. This is a useful strategy that can be applied in clinical settings.

研究目的 本研究的目的是要藉由線索暴露的實驗典範,探索長期使用安眠藥物 之患者對於安眠藥物相關刺激的注意力偏誤現象,並根據 Baker 及其同事們 (2004)與其他學者所提出的「藥物動機理論的情感模型」,強調負向情感在長 期使用安眠藥物的失眠患者所扮演的角色,本研究另欲探討長期使用失眠藥物的 患者是否在負向的情緒下能引發其對安眠藥物有更多的注意力及反應偏誤,並以 oddball 實驗典範來引發測量大腦皮質 ERP 波的注意力偏誤現象,並試圖以主觀 渴求問卷來測量個案是否在負向情感下有較強烈的主觀渴求反應。 方法 研究之有效樣本為 13 人。其中男性 5 人,女性 8 人,年齡介於 23-54 歲 (34.15 ± 11.07),參與研究之受試者會進行兩晚之實驗及多頻道睡眠生理檢查, 實驗情境分成基礎情境及挫折情境,在挫折情境中,受試者在進行較困難之認知 作業的同時,研究者會給予負向之指導語以進行情緒之操弄;而在基礎情境則給 予中性之指導語。在認知作業進行之後,開始進行線索暴露之 ERP 測量,受試 者須判斷圖片是否含有動物(目標刺激),另包含中性圖片刺激(96 張)、睡眠 相關刺激(32 張)及藥物相關刺激(32 張)。另外在認知測驗及線索暴露的前後 也會測量受試者之情緒狀態及主觀渴求狀態。研究分析以多變量變異數分析進行 檢驗。 結果 長期使用安眠藥物的患者相較於中性刺激,其對於藥物圖片刺激及睡眠相 關刺激皆有較大之 P300 及 SPW 腦波振幅。未在研究中驗證 Baker 等人提出之負 增強處理模式之因果關係,但發現,在基礎情境中,當受試者的正向情緒減少愈 多,受試者在單一題項渴求程度減少愈少;而負向情緒與其他的渴求指標較具有 相關性,研究發現當負向情緒增加愈多,單一題項渴求程度增加愈多,對藥物效 果的期待也愈高,對藥物的欲求與所帶來欣快感也會愈高,顯示情緒的改變於主 觀渴求狀態的相關性。此外本研究結果顯示客觀的腦波指標與部分主觀感受顯著 相關,其中 P300 與其對藥物的渴求程度呈正相關。 結論 無論是在基礎情境或挫折情境,長期使用安眠藥物之患者對安眠藥刺激及 睡眠相關刺激皆有注意力偏誤之現象,且此注意力偏誤現象與其對藥物的渴求程 度具有一定程度之相關性。在挫折情境中,受試者對藥物之主觀渴求有較大的傾向。 / Introduction The major goal of this study is to examine the phenomenon of craving in hypnotic use. The Affective Processing Model of Negative Reinforcement (Baker, Piper, McCarthy, Majeskie, & Fiore, 2004) suggests that negative affect would influence drug use through the change of cognitive process to a “hot information processing” and therefore increase the craving for drug use. The study explores the effects of negative affect on attentional bias and subjective craving associated with hypnotic use to test this model. Method Thirteen long-term hypnotic users were included in this study. They came to the sleep laboratory for two nights for an experimental night in which negative affect was induced by giving negative comments on their performance on a cognitive task and a control night with exactly the same procedure except that the negative comments was replaced by neutral comments. For both nights, craving was assessed with subjective ratings and measure of attentional bias with recording of event-related potentials (ERPs) induced by pictures related to hypnotic use, sleep and neutral pictures. Result The amplitude of P300 and SPW for sleep related pictures and hypnotic related pictures are significant larger than the amplitude for neutral pictures in both conditions. Also, results show that the picture of P300 are positively correlated with subjective craving for hypnotic drugs. Moreover, the data shows the tendency of condition difference in subjective craving. Conclusion The hypnotic long-term users do show attentional bias for sleep related and hypnotic related pictures. However, the result does not show more attentional bias for hypnotic related pictures in stressful situation. On the other hand, the data shows a tendency that the subjective craving is stronger in stressful situation than in baseline situation. The findings show only partial support for the Affective Processing Model of Negative Reinforcement.

睡眠失功能信念在慢性失眠的病理上扮演重要的角色，可能讓個體產生不良睡眠行為與過度睡前激發狀態，進而造成失眠。而癌症相關失眠患者由於其病理的獨特性也可能出現其獨特的睡眠失功能信念，本研究探討在癌症相關失眠的病理機轉中加入癌症相關睡眠失功能信念，是否可較單純一般慢性失眠之睡眠失功能信念對癌症相關失眠有更全面的了解。而癌症相關失眠具有許多不同於一般慢性失眠的要素，其中除了與疾病相關的特殊睡眠失功能信念外，尚有可能與睡眠困擾相關的癌因性疲憊干擾存在。因此，本研究的目的在探討：1）加入癌症相關的睡眠信念之整合睡眠失功能信念與失眠症狀的關聯性是否與單純一般的睡眠失功能信念有所不同；2）其影響路徑是否透過不良睡眠行為與睡前激發狀態影響失眠嚴重度；3）疲憊嚴重度是否使整合睡眠失功能信念對不良睡眠行為的預測力增加。本研究使用問卷調查對混合癌症患者進行各因素的測量後 (N=148)，運用結構方程模型進行路徑與因果分析，研究結果顯示，在疲憊嚴重度較高時，加入癌症相關睡眠失功能信念的整合睡眠失功能信念，其中「對失眠之負向影響預期與擔憂」向度會透過睡前生理激發狀態對「失眠對白天功能影響」程度有正向預測力、而「安眠藥物對疾病影響」向度對「失眠對白天功能影響」程度有負向預測力、不良睡眠行為對「失眠對白天功能影響」程度有正向預測力、一般睡眠失功能信念之預測路徑則多透過認知激發狀態影響；在疲憊嚴重度較低時，「對失眠之負向影響預期與擔憂」向度對「失眠對白天功能影響」程度有正向預測力、「睡眠與健康及病後修復關聯性的信念」向度對「失眠對白天功能影響」程度有負向預測力、「安眠藥物對疾病影響」向度對「睡眠困難」與「主觀痛苦」程度有正向預測力、一般睡眠失功能信念可預測之細項有所減少。研究結果顯示一般睡眠失功能信念會透過睡前認知激發影響失眠嚴重度，而加入癌症睡眠失功能信念後的整合睡眠失功能信念會透過睡前生理激發影響失眠嚴重度，疲憊嚴重度在其中扮演調節變項的角色，疲憊程度高低會使癌症睡眠失功能信念透過不同路徑影響失眠嚴重度。 / Dysfunctional beliefs about sleep play an important role in the pathological mechanism of chronic insomnia. Sleep-related behaviors and presleep arousal may mediate the relationship between the dysfunctional beliefs and severity of insomnia. Since cancer-related insomnia is associated with specific physiological and psychological conditions, there are specific dysfunctional beliefs that might have different influence to patients' sleep. Also, cancer-related fatigue could be closely related to sleep disturbance in cancer patients and demands to be explored. Therefore, the primary purpose of the current study is to explore: 1) whether adding cancer-related dysfunctional sleep beliefs to general dysfunctional sleep beliefs would show different pattern of association with severity of insomnia, comparing to the pattern of general dysfunctional sleep beliefs alone; 2) whether the sleep behavior and presleep arousal mediate the relationship between the dysfunctional beliefs to severity of insomnia in this path of model or not; 3) whether the severity of fatigue is a moderator of the predictibility of combided dysfunctional sleep beliefs to sleep-related behavior. The study recruited 148 mixed cancer diagnosis patients. They were instructed to fill out a package of questionnaires to assess their dysfunctional sleep beliefs, insomnia severity, cancer-related fatigue, etc. Structural equation modeling (SEM) was conducted for path analysis and causality test. Accroding to the result of SEM, presleep arousal was found to be a mediator of the positive association between the beliefs about “expectation and worries of negative consequence of insomnia” and daytime difficulties among subjects with high level of fatigue. Also the beliefs about “harmfulness of hypnotic” have negative predictibility to “daytime difficulty” in these subjects. Sleep behavior, on the other hand, have positive prediction to the “daytime difficulty”. General sleep dysfunctional beliefs showed pathway through presleep cognitive arousal level. For subjects with lower level of fatigue, the beliefs about “expectation and worries of negative consequence of insomnia” have positive association with the “daytime difficulty”. The beliefs about “beliefs about association between sleep and health and recovery from illnesss” were shown to have negative prediction to the “daytime difficulty”. The belief about “hypnotic related to disease” showed positive association with the “sleep difficulty” and associated “distress”. General sleep dysfunctional beliefs had less predictive factors. Based on the results of this study, adding cancer-related dysfunctional sleep beliefs was shown to have different relationship with severity of insomnia compared to general sleep dysfunctional beliefs. General dysfunctional sleep beliefs showed a pathway to insomnia severity through the mediation presleep cognitive arousal level. On the other hand, combided sleep dysfunctional beliefs showed a pathway to insomnia severity through the mediation of presleep somatic arousal level. Furthermore, severity of fatigue is a moderator. Subjets differed in the level of fatigue showed different path from combided dysfunctional sleep beliefs to severity of insomnia.

本研究嘗試檢視原發性失眠 (Primary insomnia) 患者在接受完認知行為治療後，其生理激發系統與恆定系統相關生理指標的改變，並探討其主、客觀睡眠改善與生理指標變化之間的關聯，藉以瞭解不同的生理系統在影響原發性失眠患者其主、客觀睡眠改善程度上可能的重要性。本研究透過醫師轉介，共18名原發性失眠患者 (男5人，女13人，平均年齡37.4歲) 接受7週6次的失眠認知行為治療，在接受治療的前後，分別進行一個晚上的多頻道睡眠記錄檢查與主、客觀睡眠評估。再進一步分析高頻率腦波Beta波 (14~35Hz) ，用來反應其中樞神經系統的激發，低頻率腦波Delta波 (0.5~2.5Hz) 則用來反應個案的恆定系統；另外，透過心跳變異率分析得出的參數，包括低頻率 (Low frequency，簡稱LF) 功率與高頻率 (High frequency，簡稱HF) 功率，以LF/HF的比率值測量其交感神經系統的活動，而HF/ (LF+HF) 則是測量副交感神經系統的活動。研究結果顯示個案的失眠問題在主觀睡眠評估指標上有顯著改善，而客觀睡眠評估指標與睡眠結構於入睡時間與入睡後清醒時間有顯著降低，其餘則無顯著改善。而各項生理系統指標，僅後半夜階段二的腦波的Delta波有顯著上升，其餘均無顯著地改善，而LF/HF的下降與失眠嚴重度的下降有顯著地關聯。因此，本研究顯示原發性失眠患者接受認知行為治療前後，其交感神經系統的下降與失眠嚴重度之改善有明顯關聯，推論失眠認知行為治療對於原發性失眠患者的交感神經活動的改善，可能是使其失眠嚴重度改善的關鍵。 / The present study evaluated the changes in beta and delta ranges of electroencephalogram (EEG) power and heart rate variability (HRV) after cognitive behavioural therapy for insomnia (CBT-I) to understand the effect of CBT-I on arousal system and homeostatic system. The study also examined the correlations between change of sleep measurement and the physiological index to clarify underlying mechanisms of sleep improved by CBT-I. Eighteen primary insomnia patients (5 males, 13 female, mean age = 37.4) participated in this study. The participants were scheduled to come to the sleep laboratory for polysomnographic (PSG) recording twice, one prior to CBT-I and one following CBT-I. A course of 6-session CBT-I was conducted during a period of seven weeks. Subjects’ changes in subjective ratings of sleep quality and quantity and sleep parameters in PSG were calculated. Spectrum analyses were conducted for their EEG and electrocardiogram (EKG). Beta EEG activity (14~35 Hz) was used to indicate the central nervos system (CNS) arousal level and Delta EEG activity (0.5~2.5 Hz) for the intensity of homeostatic system. Low frequency power (LF) and high frequency power (HF) of the R-R interval were calculated for heart rate variability (HRV). LF/HF ratio was used as a index of sympathetic nervous system activity and the HF/ (LF+HF) ratio as a index of parasympathetic nervous system activity. The results show subjective sleep quality of subjects were significantly improved after CBT-I. PSG shows shortened sleep onset latency and decreased wake time after sleep onset, but not in the other measures. For EEG spectrum and HRV parameters, only Delta EEG activity in stage2 of the second half of the night was significantly improved. In addition, the decrease of LF/HF significantly correlated with the improvement of the insomnia severity index. Thus, the results suggests that sleep improvements by CBT-I may be associated with the reduction of sympathetic arousal.

研究目的：在現今高壓力與忙碌的社會中，失眠是很常見的問題。在國外的失眠的相關調查結果顯示，失眠的盛行率會受對於失眠定義之嚴謹程度影響，而有大範圍的變異，其範圍約落在6~48%。當定義符合臨床上之診斷標準時，失眠盛行率約降至6~15%。因此，受失眠之苦的個體中，有一大部分可能未達診斷標準，而為暫時性或急性失眠之患者。然而過去的研究大多將重點聚焦在符合失眠疾患診斷的失眠族群上，針對剩下雖未符合失眠疾患診斷標準，但又飽受失眠症狀困擾之群體，卻是缺乏探討。此外，失眠的縱貫研究中也發現，暫時性失眠個體到最後會有一部份會發展成為慢性失眠。因此，針對這群為數不少，且容易經歷暫時性失眠之個體，若能更加了解其暫時性失眠發生的成因與相關機制，便能及早介入，協助個體不落入慢性失眠的惡性循環中。過去研究發現，暫時性失眠的發生，最常見的促發因素為壓力事件。Drake、Richardson、Roehrs、Scofield與Roth（2004）便發展出福特壓力失眠反應量表（Ford Insomnia Response to Stress Test, FIRST）來測量個體特質上遭遇壓力情境的睡眠脆弱程度；且研究結果也發現個體身心激發程度是和睡眠脆弱特質息息相關的因素之一。由於過去在失眠的相關研究中，少有研究探討暫時性失眠的相關機制，因此，本研究從和暫時性失眠相關的壓力下睡眠脆弱特質出發，探討此脆弱特質與過度激發的關聯性，並欲探討其他會提升激發程度的相關認知與情緒因子，如：失功能信念、情緒反應性、反芻特質、情緒遲惰特質和此特質間的關係。本研究假設個體對於睡眠的失功能信念與對負向事件的情緒反應性可能會透過提高睡前身心的激發程度，而使個體容易經歷壓力下的急性失眠，增加睡眠的脆弱性；即睡前身心激發程度在睡眠的失功能信念與情緒反應性對睡眠脆弱性的關係間扮演一中介作用之角色。另外，也假設睡眠的失功能信念與情緒反應性與睡前身心激發程度間的關係，會分別受反芻特質與情緒遲惰特質調節，即具有高反芻特質與高情緒遲惰特質者，其睡眠的失功能信念與情緒反應性與睡前身心激發程度間的關係更強烈，因此在壓力下，其有較高的睡眠脆弱性，容易經歷暫時性失眠。 研究方法：本研究於大學中招募60位20~35歲之受試者（男：22位；女：38位），經晤談以確認受試者符合收案標準後，將請受試者填寫研究相關問卷（包含：壓力下失眠反應量表、反芻型反應風格短版量表、睡前激發程度量表、睡眠失功能信念及態度簡式量表、情緒反應量表、失眠嚴重度量表、貝克憂鬱量表第二版與貝克焦慮量表）；並在詳細解釋情緒經驗取樣流程後，請受試者回到日常生活環境中進行連續三天的情緒遲惰經驗取樣紀錄。 研究結果：根據執行檢驗中介效果步驟的階層迴歸與Sobel test的分析結果，睡前認知激發程度對擔憂的失功能信念與情緒持續性和睡眠脆弱性間的關係具中介的作用；即對睡眠有過度擔憂的失功能信念、情緒持續性較久皆可能會提高睡前認知激發程度而增加壓力下的睡眠脆弱性。其他失功能信念之向度，如：知覺失眠造成的影響、對睡眠的期待、藥物使用，以及情緒反應性之其他向度，如：情緒敏感度與情緒激發度對睡前認知過度激發狀態無顯著的預測力。另外，根據執行檢驗調節效果步驟的階層迴歸分析結果，反芻特質與情緒遲惰特質分別在失功能信念與情緒反應性對認知激發程度的關係上，皆未有顯著的調節效果。 研究結論：研究結果部分支持身心激發程度為對睡眠的失功能信念與情緒反應性影響壓力下睡眠脆弱性的中介因子之假設。本研究發現過度擔憂睡眠的信念以及情緒持續度較久這兩個因子會分別獨立地提高睡前認知激發程度，顯示睡前認知激發程度分別受認知與情緒因素影響；且相較與睡前的生理激發狀態，睡前的認知激發對於壓力下的失眠反應之影響具有顯著的預測力，顯示認知激發在失眠的前置因子中可能扮演較重要的角色。另外，反芻特質與情緒遲惰特質分別在失功能信念與情緒反應性對認知激發程度的關係上，皆未有顯著的調節效果，此部份不符合研究預期。基於本研究結果，在臨床上對於容易經歷失眠之個體，若能及早調整對於睡眠的擔憂相關的信念，並學習有效調節情緒的方式，皆可有效降低個體睡前的認知激發活動，減少失眠的發生率與改善失眠症狀，避免使其落入失眠慢性化的惡性循環中。
