The Relationship among Anxiety, Worry, Perceived Stress, Defense Mechanisms, and High Levels of Post-Traumatic Stress Symptoms: A Discriminant Analytic Approach

Post-traumatic stress disorder (PTSD) is a pathological condition that may lead to a significant deterioration in the quality of life over time. Therefore, the study of the elements that can characterize the disorder could be considered of great clinical interest and relevance. The aim of the present research was to empirically discriminate the influence of perceived stress, state anxiety, worry, and defense mechanisms (mature, neurotic, and immature) at different levels of post-traumatic stress symptoms. A sample of 1250 participants (69.5% women, 30.5% men; M_age = 34.52, SD = 11.857) completed an online survey including the Impact of Event Scale-Revised, Ten-Item Perceived Stress Scale, Penn State Worry Questionnaire, Forty Item Defense Style Questionnaire, and State-Trait Anxiety Inventory-Form X3. Data were analysed by implementing MANOVA and discriminant analysis. Results showed significant differences in the levels of perceived stress, state anxiety, and worry, as well as neurotic and immature defenses based on the levels of post-traumatic stress symptoms: F(12,2484) = 85.682, p < 0.001; Wilk's Λ = 0.430. Furthermore, these variables discriminate significant accuracy between participants who reported a mild psychological impact and those with a probable presence of PTSD, with perceived stress, which was found to be the best predictor. Classification results indicated that the original grouped cases were classified with 86.3% overall accuracy. Such findings may provide useful insight for clinical practice.

Retrospective Analyses of Psychological Distress and Defense Style Among Cancer Patients

OBJECTIVE

Psychological distress is common in cancer patients during the diagnostic phase. Research demonstrated that anxiety, depression and defense mechanisms may influence physical and psychological well-being in patients with malignant tumors. The present retrospective study investigated the associations between clinical and psychological characteristics of cancer patients waiting for the diagnosis, focusing on metastatic cancer (MC) and breast cancer (BC).

METHOD

Patients with a new diagnosis of cancer referring to a Clinical Oncology Unit in Central Italy were interviewed during the 2017 for psychological assessment. Double-blind information about anxiety, depression, sleep disorders, defense style, and cancer diagnosis were available for the 567 patients included in this study. T-test, chi-squared and regression analyses were performed to detect associations between psychological variables and the presence of metastasis (MC) in the whole sample and in the subgroup of breast cancer (BC) patients.

RESULTS

Female gender and younger age were associated with anxiety, depression, and maladaptive defense style. A significant positive relationship was found between presence of metastasis and symptoms of anxiety. Depression resulted significantly more frequent in BC, while there was a trend close to statistical significance in MC. Immature defense style was widely used by BC women, with a score close to statistical significance.

CONCLUSIONS

This retrospective study provided empirical evidence of the relationship between psychological functioning and clinical characteristics of cancer. In line with previous research, our findings confirmed the peculiar psychological functioning of BC patients. Further investigations are needed to understand how the diagnosis of cancer may influence the individual psychological functioning and vice versa.

The Investigation of the Mediator Effect of Sexism and Defense Style in the Relationship Between Homophobia and Aggression

INTRODUCTION

Homophobia is seen all over the world and it may lead to aggressive behavior towards individuals with different sexual orientations. In this study, it is aimed to examine the mediator effect of sexism and defense style in the relationship between homophobia and aggression.

METHODS

281 students from Tekirdağ Namık Kemal and İstanbul Aydın University are included in the study. The participants filled out the Demographic Information Form, Hudson-Ricketts Homophobia Scale, Defense Style Questionnaire, Ambivalent Sexism Inventory and Aggression Questionnaire.

RESULTS

It was found that as homophobia level increased, sexism, neurotic and immature defense style increased. In addition, the relationship between homophobia and aggression was mediated by neurotic defenses and hostile sexism. Moreover, it was found that immature defense styles have a significant positive relationship with aggression.

DISCUSSION

The findings of the study suggest that homophobia is related to aggression and this relationship coincides with other findings in the literature. However, it is seen that there are findings that coincide with the literature on the mediator effect of sexism and defense styles in the relationship between homophobia and aggression.
