The general aim was to explore philosophy of life, expectations and optimism in patients and spouses in two different cancer situations, and to determine whether these aspects had relevance for psychological distress and quality of life. The first situation was being newly diagnosed with advanced cancer. Data on philosophy of life, optimism and psychological distress were gathered on one occasion (I). In addition, changes in life were described using a qualitative approach in a sub-sample (II). The second situation was having completed curative cancer treatment. Data on expectations for the recovery period, optimism, psychological distress and quality of life were gathered on three occasions (III). Moreover, expectations and how these turned out were described using a qualitative approach in a sub-sample (IV). The results show that being diagnosed with an advanced cancer influenced aspects of patients’ and spouses’ philosophy of life, including that existential questions were common and were related to higher psychological distress (I). All experienced substantial mental changes in life, often also physical, practical and sometimes positive changes. Patients more often seemed to accept their situation and prepared themselves for death, whereas spouses had more difficulties in handling the situation (II). Patients who had completed curative treatment generally had higher expectations for the recovery period than did their spouses, and patients expectations were fulfilled to a lesser degree, however, this generally had little importance for psychological distress or quality of life (III). Patients’ expectation for their recovery period was generally that they would get well. For those whose recovery period had been tough, expectations were often unfulfilled, but they were often satisfied with their current life anyway owing to positive changes (IV). Being optimistic was the most beneficial for decreased psychological distress in both samples, as well as for better quality of life in the recovery group (I, III).

Purpose The main purpose of this paper is to investigate overconfidence and over-optimism in the market. This leads the reader to the question, are the analysts “right” concerning their forecasts? The reader will also get to understand various and sometimes forgotten factors that affect we human beings in our decision making when it comes to investing and analysing which is also known as the behavioural finance theory. Conclusion According to the results from my tests it seems that analysts of the S&P500 are exaggerated by the problem of overconfidence and the over-optimistic biases. The analysis part of this study is confirming the discussed theory of anchoring and herding. Analysts tend to “follow the stream”, by evaluate the standard deviations between forecasts and the realized outcome, as well as the indexed analysts’ consensus estimations for twenty-four months of EPS.

Att föda barn är förenat med smärta. Fokus ligger idag på att minska eller göra smärtan hanterbar för att ge kvinnan en positiv förlossningsupplevelse. Copingstrategier är effektiva hjälpmedel för smärthantering och personligheten kan påverka effektiviteten av dem. Studiens syfte var att undersöka vilka copingstrategier som förknippas med en tillfredsställande förlossningsupplevelse och om graden av optimism kan ses påverka valet av dem. Enkäter besvarades av 26 förstföderskor inom 24 timmar efter barnets födelse. De mer optimistiska kvinnorna använde sig mer av närmande coping (r = 0,53; p = 0,001) som innefattas av att söka emotionell och instrumentell support, att acceptera och agera aktivt för att hantera sin situation. Och användandet av närmande strategier var i sin tur förknippat med en mer positiv förlossningsupplevelse (r = 0,50; p = 0,05) där optimism och närmande coping tillsammans stod för 30 % av variansen. Kunskapen om hur optimism påverkar copingbeteendet kan effektivisera strategianvändandet under förlossningen.

This study investigated the experience of posttraumatic growth for breast cancer survivors who volunteered to complete a survey (N = 277). A number of participants also provided narrative responses containing their personal experiences of breast cancer (N = 100). Demographic characteristics, breast cancer variables, optimism, coping strategies, and participation in psychosocial interventions were examined in relation to posttraumatic growth as measured by the Posttraumatic Growth Inventory. Differences between those who participated in psychosocial interventions versus those who did not were examined. The relation of coping strategies utilized and optimism level to interventions accessed was also of interest. Predictors of posttraumatic growth were examined via generalized linear modeling. Finally, the narrative responses were investigated by means of content analysis. The results provided evidence that demographic characteristics (i.e., affiliation with religion and lower levels of education) and one breast cancer variable (i.e., increased number of years since diagnosis) were related to experiences of posttraumatic growth for breast cancer survivors. Use of active forms of coping, optimism level, and participation in recreational interventions were also related to posttraumatic growth. Those who participated in psychosocial interventions were more likely to be employed and have higher levels of education than those who did not access interventions. Use of several active coping strategies and one passive coping strategy increased the likelihood of accessing a number of different psychosocial interventions. Posttraumatic growth was predicated by affiliation with religion, lower levels of education, increased number of years since diagnosis, knowledge of breast cancer stage, higher levels of optimism, and use of one passive and two active coping strategies. Many of these findings support previous research, however some conflict with prior results. The narrative responses contained information regarding diagnosis and treatment, impact of breast cancer, coping with breast cancer, and support accessed. Although the negative impact of breast cancer was discussed in terms of short and long-term, positive long-term changes were also reported. A variety of coping strategies and supports were utilized by the participants as well.

The aim of the represent research was to investigate the relationship between illusion of control, optimism bias, locus of control, and drivers&rsquo / risk-taking behavior among Turkish drivers. A total of 307 drivers completed the Driver Behavior Questionnaire, the Driver Skills Inventory, the Optimism Bias Scale, the Multidimensional Traffic Locus of Control Scale, and Rotter&rsquo / s Internality Externality Scale. In chapter one, comparison between perceived risk as driver and perceived risk as passenger demonstrated existence of illusion f control among drivers. Drivers&rsquo / risk assignments were different when imagining themselves as drivers and passenger. Illusion of control was found to be related to the total number of accidents, especially involvement in active accidents. This indicates a positive relationship between illusion of control and risk-taking behavior. In the second chapter, optimism bias was found in drivers&rsquo / risk likelihood estimations for accident involvement in the future. Drivers estimated their risk of being involved in four types of accidents as less than an average driver. Optimism bias was related to self-reported violations and strong evaluation of driving and safety skills as strong. Young and novice drivers were more realistic in their risk estimations. In the third chapter, relationship between locus of control and risk-taking was investigated. Only fate scale correlated with violations. Drivers who attribute accident causes to fate were more likely to commit violations. The limitations of the current research and implications for further research were discussed.
