The aim of the study was to test three mediation and a moderation models in order to investigate the mediating role of coping styles and both mediating and moderating roles of perceived social support between dispositional hope-posttraumatic growth/PTSD relationships among postoperative breast cancer patients. Accordingly, it was hypothesized that 1) Problem-focused coping styles (PFC) would mediate the relationship between dispositional hope and posttraumatic growth among postoperative breast cancer patients. 2) Emotion-focused coping style (EFC) would mediate the relationship between dispositional hope and posttraumatic stress disorder among postoperative breast cancer patients. 3) Perceived social support would mediate the relationship between dispositional hope and posttraumatic growth among postoperative breast cancer patients. 4) Perceived social support would moderate the relationships between dispositional hope and posttraumatic growth among postoperative breast cancer patients. The study was conducted with 73 postoperative breast cancer women (mean age = 44.44, SD = 7.43) who were undergoing postoperative chemotherapy and radiotherapy. Participants were from different cities but receiving treatment from Dr. Abdurrahman Yurtaslan Ankara Oncology Education and Research Hospital. Measurements were applied orally to participants. According to results of the study, PFC did not mediate the relationship between dispositional hope and PTG and its subscales. Similarly, the relationship between dispositional hope and PTSD and its subscales was not mediated by EFC. Beside, perceived social support and its sources did not mediate the relationship between dispositional hope and PTG and its subscales. However, perceived social support and perceived social support from friend moderated the relationship between dispositional hope and PTG. Results, limitations, clinical implications of the study and directions for future studies were discussed in the light of the literature.

The purpose of this study was to investigate the dispositional optimism-posttraumatic growth (PTG) relationship in postoperative breast cancer patients and to examine if perceived social support moderates this relationship. The study was conducted with 104 women undergoing postoperative chemotherapy treatment or coming to the hospital for their routine controls. Hierarchical multiple regression analyses indicated that breast cancer survivors high on dispositional optimism and perceived social support, are m...

The general aim of the present dissertation was to examine the coping processes of the caregivers of children with cancer. It was composed of three studies, whose aims were (1) to reveal the predictors of caregiver distress by using the Transactional Theory of Coping among the caregivers of children with cancer; (2) to identify the factors associated with caregiving process from the caregiver’s perspective qualitatively; (3) to develop and implement an intervention program. Study 1 was conducted with 105 pa...
The effect of dispositional optimism on posttraumatic growth: Testing the moderator role of ways of coping between dispositional optimism and posttraumatic growth in Turkish breast cancer patients
Bozo Özen, Özlem; Gündoğdu-Aktürk, Elçin (2008-06-01)
The aim of the present study was to examine if coping strategies mediate dispositional optimism–posttraumatic growth relation in postoperative breast cancer patients. The data were collected from 90 patients in two hospitals. Regression analyses revealed that problem-focused coping fully mediated dispositional optimism–posttraumatic growth relation, but emotion-focused coping did not. That is, postoperative breast cancer patients who were optimistic were more likely to use problem-focused coping strategies ...

Yarış, Seval; Bozo Özen, Özlem; Department of Psychology (2010)
The aim of the present study was to investigate the role of metacognition as a mediator of the relationship between smoking dependence and depression/anxiety/ negative impact of life experiences. A sample of 202 adult smokers completed the following questionnaires: Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Life Experiences Survey (LES), Meta-Cognitions Questionnaire-30 (MCQ-30), and Fagerström Test of Nicotine Dependence (FTND). The path analyses were used to test a mediation model in w...
The Moderating role of sensory-processing sensitivity in the relationship between spousal caregiving, perceived social support and marital quality
Şengül İnal, Gülbin; Sümer, Nebi; Department of Psychology (2014)
This thesis aims to examine the moderating role of sensory-processing sensitivity (SPS) in the relationship between caregiving, perceived social support and marital quality. Specifically, in two studies the role of SPS was tested by comparing the three trait-environment interaction approaches, namely (1) diathesis-stress model, (2) differential susceptibility hypothesis, and (3) vantage sensitivity model, using the Actor-Partner Interdependence Model (APIM). It was expected that if SPS has a moderating effe...
