Life satisfaction in patients with chest pain subsequently diagnosed as coronary heart disease – connection through depressive symptoms? 总被引:3,自引:0,他引:3
Valkamo M. Koivumaa-Honkanen H.-T. Hintikka J. Niskanen L. Honkalampi K. Viinamäki H. 《Quality of life research》2003,12(8):1099-1105
The aim of this study was to investigate factors associated with life dissatisfaction in symptomatic patients (n = 144) with chest pain subsequently diagnosed as coronary heart disease (CHD) by coronary angiography. Life dissatisfaction was assessed with a four-item life satisfaction scale (LS), depression with the 21-item Beck Depression Inventory (BDI) and other psychiatric symptoms with the symptom check list (SCL). DSM-III-R Axis I and Axis II psychiatric diagnoses were performed by means of the Structured Clinical Interview. All assessments took place one day before angiography. Twenty-four per cent of CHD patients were dissatisfied with their lives. Life dissatisfaction was associated with being unmarried. Dissatisfied patients had Axis I mental disorders and Axis II personality disorders more frequently than others. Psychiatric and depressive symptoms according to the SCL and BDI, respectively, were also higher among dissatisfied patients. In multiple logistic regression analyses, mental disorders were related to life dissatisfaction when age, sex, employment status, New York Heart Association class, duration of chest pain symptoms and work load were controlled in the model. Married subjects had a lower probability of being dissatisfied with their lives than other subjects (Odds Ratio, OR: 0.23). When BDI scores were included in the model, the only factor independently associated with life dissatisfaction was the severity of depressive symptoms (OR: 1.81). To conclude, life dissatisfaction is not primarily determined by the severity of CHD but by the existence of depressive symptoms. 相似文献

Alexithymia was measured in non-treatment seeking, community-dwelling Holocaust survivors using the Toronto Alexithymia Scale—Twenty Item Version (TAS-20). Scores of survivors with (n = 30) and without (n = 26) posttraumatic stress disorder (PTSD) were compared, and associations among alexithymia, severity of trauma, and severity of PTSD symptoms were determined. Survivors with PTSD had significantly higher scores on the TAS-20 compared to survivors without PTSD. TAS-20 scores were significantly associated with severity of PTSD symptoms, but not with severity of trauma. This study adds to our knowledge of the relationship between alexithymia and trauma by demonstrating that this characteristic is related to the presence of posttraumatic symptoms and not simply exposure to trauma. 相似文献

Psychological factors influencing the surgical patients' consent to regional anaesthesia 总被引:2,自引:0,他引:2
M. N. PAPANIKOLAOU A. VOULGARI L. LYKOURAS Y. ARVANITIS G. N. CHRISTODOULOU A. DANOU–ROUSSAKI 《Acta anaesthesiologica Scandinavica》1994,38(6):607-611
To investigate the preoperative attitude of surgical patients to regional anaesthesia, 162 subjects scheduled for elective surgery were studied. On the day before operation, patients were interviewed by an anaesthesio–logist, using a semi–structured schedule. Topics investigated were sociodemographic variables and clinical correlates, such as past anaesthetic experience, information about anaesthesia and surgery, as well as questions and fears related to anaesthesia. Subjects were assessed for personality characteristics and emotional symptoms by Eysenck's Personality Questionnaire (EPQ), Zung's Self–rating Anxiety and Depression Rating Scales, Schalling–Sifneos' Personality Scale and the 43–item Life Events Inventory of Holmes and Rahe. Seventy–one patients (44%) consented to regional anaesthesia. Consent to regional anaesthesia was associated with advanced age, low neuroticism and high extroversion score in the EPQ, as well as longer duration of illness. The deniers of consent asked more questions and expressed more fears about anaesthesia. It is suggested that the patients' characteristics influence their preference, acceptance or refusal of regional anaesthesia. 相似文献

抑郁症患者的述情障碍与焦虑、抑郁的相关性研究 总被引:1,自引:1,他引:1
目的 探讨抑郁症患者的述情障碍以及与焦虑、抑郁的关系.方法 采用多伦多述情障碍量表(Toronto Alexithymia Scale, TAS)、Hamilton焦虑量表(Hamilton Anxiety Scale,HAMA)及Hamilton抑郁量表(Hamilton Depression Scale,HAMD)对100例抑郁症患者和100例正常自愿者进行测评,并对述情障碍与焦虑、抑郁作相关分析.结果 抑郁症组TAS评分显著高于正常对照组0=6.86,P<0.01);其述情障碍的发生率为43%,亦显著高于对照组的11%(x2=25.98,P<0.01).抑郁症患者的TAS总分及因子Ⅰ、Ⅱ、Ⅳ评分与HAMA及HAMD评分均呈显著性正相关.结论 抑郁症患者存在着明显的述情障碍,并与焦虑、抑郁有关. 相似文献

青少年强迫症病人父母的述情障碍研究 总被引:5,自引:0,他引:5
目的 探讨青少年强迫症病人父母的述情障碍和心理健康状况及其关系。方法 使用TAS、SCL—90对102例13—19岁青少年强迫症病人父母共102人和心理健康青少年的父母89人进行测评。结果 强迫症病人父母的述情障碍总分、因子Ⅰ—Ⅳ均高于对照组(P<0.01);SCL—90中的身体化、强迫、忧郁、焦虑、敌对、偏执、精神病性等因子分阶段和总分均显著高于对照组(P<0.01)。59例(57.84%)有心理问题。强迫症病人父母TAS总分与SCL—90中的躯体化(P<0.01)、强迫(P<0.01)、焦虑(P<0.01)和精神病性(P<0.01)正相关;与敌对性(P<0.01)负相关。结论 强迫症病人父母常常有述情障离、心理健康问题。给予强迫症病人父母心理帮助经常是必要的。 相似文献

We investigated alexithymia, a deficit in the ability to identify and describe one's emotions, in a sample that included patients with neurodegenerative disease and healthy controls. In addition, we investigated the relationship that alexithymia has with behavioral disturbance and with regional gray matter volumes. Alexithymia was examined with the Toronto Alexithymia Scale-20, behavioral disturbance was assessed with the Neuropsychiatric Inventory, and regional gray matter volumes were obtained from structural magnetic resonance images. Group analyses revealed higher levels of alexithymia in patients than controls. Alexithymia scores were positively correlated with behavioral disturbance (apathy and informant distress, in particular) and negatively correlated with the gray matter volume of the right pregenual anterior cingulate cortex, a region of the brain that is thought to play an important role in self and emotion processing. 相似文献
