本研究主要目的在於探討在不同情緒經驗及反芻風格對男女性自傷行為的影響。回顧過去研究，情緒被認為是多數自傷者自傷的動機及原因之一。可惜的是，大多數研究聚焦在負向情緒經驗，而較少探討正向情緒及不同激發程度的影響力。Selby（2008）的情緒瀑布理論提出反芻風格能夠增加負面情緒強度的論點，也暗示了反芻風格也是另一個與自傷行為相關認知因子。因此本研究認為情緒經驗與反芻風格可能皆為自傷發生的關鍵。有鑑於許多文獻結果指出，男女性的自傷危險因子可能存在差異，本研究便把性別差異納入考量，欲了解男、女性是否在情緒經驗及反芻風格的自傷預測因子有所不同。 本研究對象為508位北部某私立高職部學生，請學生填寫包含基本資料、反芻風格、自傷狀況及情緒經驗的評估共四部份問卷。研究結果顯示，在預測過去一年自傷行為的因子上，的確有性別差異。對女性來說，預測過去一年是否自傷的有效因子分別為負向情緒及負向低激發情緒，男性則是負向情緒及正向低激發情緒。在自傷頻率方面，對男女性來說，沒有任何情緒經驗或反芻風格為有效預測因子。在自傷種類數方面，沒有任何情緒經驗或反芻風格為女性自傷頻率的有效預測因子；對男性來說，則是負向情緒及低激發情緒能夠有效預測過去一年自傷種類多寡。研究最後針對這樣的結果做進一步討論及提供實務上的意涵及應用。 / The purpose of the present study was to investigate the influence of emotion experiences and rumination styles on Non-suicidal self-injury behavior (NSSI) in males and females. According to past studies, emotion was considered a critical factor in motivating individuals to practice NSSI. However, most studies focused on negative emotion experiences, and ignored the role of positive emotions and the effect of emotion activation level. Moreover, Selby’s Emotional Cascade Model proposes that rumination style will increase the negative affect intensity, suggesting that rumination style may be another key factor to NSSI. In addition, due to several studies have shown gender differences in risk factors for NSSI, the gender difference will be also take into account in the present study. To sum up, the present study aimed to examine gender differences in predictors (i.e., emotion experiences and rumination styles) for NSSI. The participants were 508 high school students from one of the private vocational high school in Northern Taiwan. All participants were asked to fill out the questionnaire pack which included demographic questionnaire, short-form rumination style questionnaire, deliberate self- harm inventory, and affect valuation inventory. The results show that gender differences in predicting NSSI existed: First, in predicting the occurrence of NSSI in the past year, negative affect and low arousal negative emotion were the most effective factors for females; negative emotion and low arousal positive emotion were the most effective ones for males. Second, neither emotion experience nor rumination style can predict the frequency of NSSI in the past year for males and females. Third, in predicting the numbers of types of self-injury used in the past year, there was no effective predictor for females; negative emotion and low arousal emotion were the effective predictors for males. Finally, the results and the practical implication were discussed in the thesis.

Non-suicidal self-injury (NSSI) is increasingly understood as representing a public health concern and a behavioral marker of emotional and psychological distress among young people. NSSI is prevalent during the period of young adulthood, including among emerging adults pursuing a university education, yet the vulnerability factors associated with NSSI in this population merit more in-depth and contextualized investigation. The current dissertation's overarching objective was to better understand the risk context surrounding university students' engagement in NSSI. Using a sample of 2,579 students (75.2% female; Mage=18.97; SDage=1.54), Study 1 first explored the roles of parental (mother and father pressure) and intrapersonal (emotion dysregulation, academic coping, perfectionism subtypes) risk factors in university students’ likelihood and frequency of engagement in NSSI in the past year. An integrated latent structural equation model revealed that higher levels of perceived mother and father pressure were associated with a greater likelihood of past-year NSSI engagement in the university student sample. Among intrapersonal risk factors, only emotion dysregulation was found to be associated with higher NSSI likelihood and frequency. Building upon these results, Study 2 sought to narrow in further on understanding the emotion regulation profiles of university students with a past-year history of NSSI. Using a person-centered statistical approach, university students who reported having engaged in NSSI within the past year (n = 479; 83.8% female; Mage = 18.77; SDage = 1.43) were classified into latent profiles based on their self-perceived difficulties in regulating both positive and negative emotions. Independent samples of students who had a past history of NSSI but had not self-injured within the previous year (n = 439; 82.9% females; Mage = 19.03, SDage = 1.62) and who had no history of NSSI (n = 1551; 69.9% females; Mage = 19.02, SDage = 1.55) were included as comparison groups. Latent cluster analyses uncovered three emotion regulation profiles within the NSSI sample - the Average Difficulties (47.4%), Dysregulated (33.0%), and Low Difficulties (19.6%) profiles - each of which differed meaningfully from both comparison samples on mean levels of emotion regulation difficulties. Students across the three profiles also differed in their self-reported experiences with parents, particularly with fathers (perceived pressure, antipathy, unresolved attachment, psychological control), and in the extent to which they felt alienated from parents. Lastly, students across profiles differed in the frequency, methods, functions, and addictive properties of their NSSI. Taken together, findings from the current dissertation expanded our awareness of vulnerability factors for NSSI that have historically been understudied (e.g., parental pressure, father-child relationships, dysregulated positive emotions), while also bringing into focus the notion that even well-established NSSI risk factors (emotion regulation difficulties) can manifest quite heterogeneously amongst university students with a history of self-injurious behavior.

Självskadebeteende är relativt vanligt förekommande bland personer med psykisk ohälsa. Återhämtning är ett begrepp som beskriver hur en person kan återerövra och finna kvalitet i sitt liv trots svår sjukdom. Självskadebeteende innebär ett stort lidande för individen och påverkar närstående i personens omgivning negativt. Syftet med denna litteraturstudie var att utifrån egenerfarnas perspektiv sammanställa kunskap om vad som främjar återhämtning vid självskadebeteende. Metoden för studien var en integrerad litteraturöversikt, vilken utgick från 15 vetenskapliga artiklar och resulterade i 6 kategorier. I resultatet framkom att återhämtning hos personer med självskadebeteende kunde främjas av att komma till en vändpunkt, att vara i gemenskap med andra med liknande erfarenheter, att få stöd av närstående, att få professionellt stöd, att förstå och kunna hantera svåra känslor och handlingar, och av att finna inre styrka. Forskning visade även att det bland vårdpersonal florerade negativa attityder och brister i förhållningssättet mot personer med självskadebeteende, vilket motverkade deras återhämtning. Vår slutsats är att etiska reflektioner i arbetsgruppen, handledning, stöd, samt utbildningsinsatser till vårdpersonal är angeläget för att öka förståelsen och höja kompetensen angående självskadebeteende; samt för att minska negativa attityder och förbättra omvårdnaden av personer med självskadebeteende på ett sätt som främjar deras återhämtning.

本研究結合Clark與Watson（1991）的三角模式（Tripartite Model）以及Brown、Chorpita和Barlow（1998）提出的階層性概念，結構正向情感、負向情感、焦慮、憂鬱、無望感、自傷、自殺的關係，建立自傷與自殺的階層預測模式，說明自傷與自殺的同異處。研究對象為487位大學生，325位女性與162位男性，採取自陳式問卷的方式施測，包含自我傷害行為量表、自殺危險程度量表、貝克無望感量表、正負向情感量表、症狀檢核表-90-修正版（摘錄測量焦慮與憂鬱的題目）、相關背景變項的測量，並以描述性統計、相關性考驗、階層迴歸分析、結構方程模式等統計方式對資料進行處理。主要的研究結果為：（1）負向情感能預測與解釋焦慮和憂鬱，且能透過焦慮預測自傷與自殺，唯焦慮對自傷的解釋力較高；負向情感亦能透過憂鬱預測自殺，但無法透過憂鬱預測自傷。（2）正向情感能預測與解釋憂鬱，且能透過憂鬱預測自殺。（3）加入無望感分析後，發現憂鬱能透過無望感預測自殺，憂鬱也能直接預測自殺，顯示無望感為憂鬱與自殺的部分中介變項。最後，結果發現有15.81%的自傷比例、24.64%的自殺意念比例、8.01%的自殺企圖比例。 / This study combined Clark & Watson’s (1991) tripartite model with Brown, Chorpita, and Barlow’s (1998) hierarchical model to structure the relationship of positive affect (PA), negative affect (NA), anxiety, depression, hopelessness, non-suicidal self-injury (NSSI), and suicide. This study attempted to establish hierarchical predictor model of NSSI and suicide, and explain the relationship of NSSI and suicide. The participants were 487 university students, 325 females and 162 males, who were participating in a study of test of deliberate self-harm inventory, suicide risk inventory, Beck hopelessness scale, positive and negative affect schedule, symptom checklist-90-R, and background variables. The data were examined by descriptive statistics, correlation, hierarchical analysis, and structural equation modeling. The main results were : (1) NA could predict anxiety and depression ; anxiety could not only mediate the relationship of NSSI and NA, but also mediate the relationship of NA and suicide ; anxiety accounted for more of the variance in NSSI than in suicide ; depression could mediate the relationship of NA and suicide, but could not mediate the relationship of NSSI and NA. (2) PA could predict depression, and depression could mediate the relationship of PA and suicide. (3) the role of hopelessness was partial mediator of depression and suicide. Finally, the result found 15.81% NSSI, 24.64% suicidal ideation, and 8.01% suicidal attempt.
