Objectives : The Public Health Research Foundation Stress Checklist (Short Form) (PHRF-SCL (SF) hereinafter) is a scale for measuring stress response in adults. It consists of four subscales ( “Feelings of Anxiety and Uncertainty”, “Fatigue and Physical Symptoms”, “Autonomic Symptoms”, and “Feelings of Depression and Inadequacy”), and has been verified in terms of reliability and validity. On the other hand, egograms have been shown to be associated with mental health and physical disorders. Therefore, in order to confirm the construct validity of PHRF-SCL (SF), we examined its association with Self-growth Egogram (SGE hereinafter).
Subjects : 233 patients visiting the department of psychosomatic medicine
Method : Subjects were requested to complete a PHRF-SCL (SF) and SGE.
Results : Four separate clusters were abstracted from a cluster analysis of SGE results, namely “High-A ‘W’ Type”, “Low-A ‘M’ Type”, “Low-FC ‘V’ Type”, and “High NP ‘へ’ Type”. For each type, we calculated the deviation value for each subscale of the PHRF-SCL (SF) and examined the difference in average using a one-way analysis of variance. The results showed that all stress responses for the “Low-FC ‘V’ Type” were higher than the other types, and that those for the “High-NP ‘ヘ’ Type” were lower than the other types. In addition, whereas the “High-A ‘W’ Type” scored high for “Feelings of Anxiety and Uncertainty” and “Feelings of Depression and Inadequacy” and scored average for “Autonomic Symptoms” and “Fatigue and Physical Symptoms”, the “Low-A ‘M’ Type” scored low for “Feelings of Anxiety and Uncertainty” and “Feelings of Depression and Inadequacy” even though scores for “Autonomic Symptoms” and “Physical Symptoms of Fatigue” were also average.
Conclusion : A relationship was observed between stress response and ego-state as revealed by SGE, which was consistent with previous studies. The construct validity of the PHRF-SCL (SF) was thus partially verified.
