There are no useful scales that assess romantic jealousy multidimensionally in Japanese, and also, many issues that need improvement can be noted in representative jealousy scales such as the Multidimensional Jealousy Scale by Pfeiffer & Wong (1989). This study was conducted to develop the Multidimensional Scale of Jealousy in Romantic Relationships to assess components of romantic jealousy referred to in previous studies and to make some improvements. Three components of romantic jealousy were hypothesized: suspicious cognition, exclusive emotion, and cautious behavior. The results from 234 undergraduates showed three factors indicated by exploratory/confirmatory factor analysis and high internal consistency. The results also showed concurrent validity with the “Mania love style” and construct validity with scales measuring fear of abandonment, reassurance-seeking, and intimacy.
The purpose of this study was to create a scale to measure career development levels in female university students and identify any influences exerted by attachment to parents. The findings revealed that a secure base of attachment to parents had a positive influence on realization, commitment, planning, and goal setting in career development. In addition, the safe haven of attachment to parents had a positive influence on self-understanding.
The purpose of the present study was to investigate features and the structure of life skills in persons with high levels of sense of coherence (SOC). Welch's t-test indicated that the persons with the higher level of SOC showed higher life skills in planning, knowledge summarization, self-esteem, positive thinking, intimacy, and leadership than those with a lower level of SOC. Moreover, hierarchical cluster analysis by Ward method and structural equation modeling suggested that persons with the higher level of SOC showed life skills with a consistent hierarchical structure.
