OBJECTIVE The objective of this study was to determine how age and psychological characteristics assessed prior to diagnosis could predict psychological distress in outpatients immediately after disclosure of their diagnosis. METHODS This is a longitudinal and prospective study, and participants were breast cancer patients and patients with benign breast problems (BBP). Patients were asked to complete questionnaires to determine levels of the following: trait anxiety (State-Trait Anxiety Inventory), negative emotional suppression (Courtauld Emotional Control Scale), life stress events (Life Experiences Survey), and psychological distress (Profile of Mood Status) prior to diagnosis. They were asked to complete a questionnaire measuring psychological distress after being told their diagnosis. We analyzed a total of 38 women diagnosed with breast cancer and 95 women diagnosed with a BBP. RESULTS A two-way analysis of variance (prior to, after diagnosis × cancer, benign) showed that psychological distress after diagnosis among breast cancer patients was significantly higher than in patients with a BBP. The multiple regression model accounted for a significant amount of variance in the breast cancer group (model adjusted R(2) = 0.545, p < 0.001), and only trait anxiety was statistically significant (β = 0.778, p < 0.001). In the BBP group, the multiple regression analysis yielded a significant result (model adjusted R(2) = 0.462, p < 0.001), with trait anxiety and negative life changes as statistically significant factors (β = 0.449 and 0.324 respectively; p < 0.01). CONCLUSIONS In both groups, trait anxiety assessed prior to diagnosis was the significant predictor of psychological distress after diagnosis, and might have prospects as a screening method for psychologically vulnerable women.

Goals of workThe objective of this study was to determine how psychological characteristics, subjective symptoms, a family history of breast cancer, and age impact psychological distress in outpatients at the first hospital visit prior to breast cancer diagnosis.Materials and methodsParticipants were prediagnosed women with complaints of breast symptoms who either came to our hospital directly, or with a referral from another clinic. Patients were asked to complete questionnaires to determine the following: trait anxiety (State-Trait Anxiety Inventory), negative emotional suppression (Courtauld Emotional Control Scale), life stress events (Life Experiences Survey), and psychological distress (Profile of Mood States). We examined subjective symptoms (lumps, pain, abnormal nipple discharge, or deformed nipple) and family history of breast cancer based on answers to the interview sheet filled out by patients on their first visit. We analyzed a total of 154 patients who completed the questionnaires out of 237 eligible patients.Main resultsA significant model was obtained by multiple regression analysis (adjusted R2 = 0.574, p < 0.01) in which the standard partial regression coefficients for trait anxiety, suppression of anxiety, negative life change events, positive life change events, and subjective symptoms were statistically significant (β = 0.623, 0.133, 0.155, 0.108, and 0.124, respectively; p < 0.05).ConclusionsPsychological distress prior to diagnosis was higher in patients who had high trait anxiety, suppression of anxiety, many life stress events, and subjective symptoms. In particular, trait anxiety had a large impact on psychological distress, underscoring the need for and importance of adequate psychological care.

OBJECTIVE The purpose of this study was to qualitatively examine the content of the psychological responses in interviews with breast cancer outpatients receiving initial medical consultation. METHOD The participants were 180 people who visited the breast cancer outpatient clinic at Kitasato University Hospital between November 2004 and August 2005. The remaining 176 participants (39 breast cancer patients and 137 benign tumor patients; average age +/- SD: 50.7 +/- 12.4 years) were analyzed. Two clinical psychologists carried out the interview, asking the participants to speak freely about their anxieties, worries, thoughts, and feelings up until the medical examination. This study used a content analysis of interviews to chronologically examine psychological response of cancer patients seeking medical consultation at three points in time. RESULTS Patients at the time of their first outpatient breast cancer consultation experience negative feelings before the examination, directly influenced by the suspicion of cancer. These include anxiety and worries, fear, evasion, depression, and impatience. These tendencies do not change at the time of consultation. However, in addition to negative feelings, some people also possess positive feelings, either simultaneously or at a different point in time. Further, many patients tend to talk at length about psychological responses before seeking treatment, understanding the process they went through to come to seek treatment as an important event. SIGNIFICANCE OF RESULTS It is important for medical workers to bear in mind the psychological conflicts that patients may undergo before seeking treatment and ensure that sufficient communication takes place.

OBJECTIVE The purpose of this study was to examine the relationship between emotional suppression and psychological distress in breast cancer patients after surgery. We examined this relationship using questionnaires at the first visit to the breast cancer outpatient clinic at our hospital and after surgery, as well as interviews after surgery. METHODS A total of 31 breast cancer patients were asked to complete the Courtauld Emotional Control Scale and the Profile of Mood States at their first visit to the outpatient clinic. Patients were also asked to complete the Profile of Mood States between 1 and 6 months after surgery. Trained clinical psychologists conducted the interviews, asking patients to speak freely about their current anxieties, worries and thoughts. Based on the median Courtauld Emotional Control Scale score of 42 points, participants were divided into emotional suppression and emotional expression groups. RESULTS The Total Mood Disturbance score, as well as each of the subscale (except vigor) scores of the Profile of Mood States, were significantly higher in the emotional suppression group than the emotional expression group. The emotional suppression group expressed significantly more negative emotions and fewer positive emotions than the emotional expression group. CONCLUSIONS Patients with emotional suppression felt and expressed more psychological distress after surgery. This finding highlights the need for medical staff to comprehend the psychological traits of breast cancer patients, including emotional suppression, in the early stages of breast cancer in order to provide adequate psychological support.
