This study investigated the reliability and validity of the Japanese version of the Oxford Schizotypal Personality Scale (STA). Participants included two samples of undergraduates. The results showed high internal consistency and test-retest reliability. The STA had significant positive correlations with the Oxford-Liverpool Inventory of Feeling and Experiences, and the Paranoia Checklist. It was not correlated with the Rosenberg Self-esteem Scale and the Liebowitz Social Anxiety Scale. This indicates that the STA has good psychometric properties and convergent and discriminant validity. These results indicate that the Japanese version of the STA is a highly reliable and valid scale of positive schizotypal personality characteristics.
This study investigated successive changes of psychophysiological responses related to social anxiety using a speech task. Fifteen university students completed the Fear of Negative Evaluation Scale (FNE) and the Go/No-go Association Task (GNAT) which measured their implicit associations between social situations and emotions. During a speech task, psychophysiological responses (electro-dermal activity: EDA; heart rate: HR) were assessed. The results showed that both EDA and HR were reduced through the speech task. For EDA, however, there was a significant difference between high and low GNAT groups. The implications for implicit variables are discussed.
This study tested the effects of hardiness on subjective stress after acute stress. Forty-eight students answered a hardiness scale and were administered the 20 min Uchida–Kraepelin psychodiagnostic test. Subjective stress was measured with the Phasic Stress Scale (PSS) before and after the task. Then, participants filled out questionnaires appraising the stressor. The low-hardiness group (n=24) showed more subjective stress than the high-hardiness group (n=24). However there were no significant differences between the two groups in the appraisal of the stressor. The results suggest that hardiness decreases the subjective stress, even though the participants did the same amount of a stressful task and had the same appraisal of it.
