The psychosocial inventory of ego strengths (PIES) was devised as a measure of Erikson's eight ego strengths. The present investigation extended previous research through examination of the validity and reliability of the PIES among 502 high school students. The study also included an appraisal of Erikson's ego strengths as indices of psychosocial well-being. Reliability of the subscales of the PIES was shown through acceptable Cronbach's alphas. As expected, higher scores on ego strengths were positively correlated with psychosocial indictors of identity achievement, self-esteem, locus of control, empathic concern, perspective-taking, and positive forms of coping. Lower scores on ego strengths were related to less desirable psychosocial constructs. Biological sex and age differences also are reported. Based on the findings, the study offers validation of psychosocial theory. As well, the PIES is recommended for use among high school students.
自我力量心理社会量表（PIES）是作为衡量埃里克森的八种自我力量的一种工具而设计的。本调查通过检验PIES在502名高中生中的有效性和可靠性，扩展了先前的研究。该研究还包括对埃里克森的自我力量作为心理社会幸福感指标的评估。PIES各分量表的可靠性通过可接受的克朗巴哈系数得以体现。正如预期的那样，自我力量得分较高与身份认同成就、自尊、控制点、共情关注、观点采择和积极应对方式等心理社会指标呈正相关。自我力量得分较低与不太理想的心理社会结构相关。研究还报告了生物性别和年龄差异。基于这些发现，该研究为心理社会理论提供了验证。此外，建议在高中生中使用PIES。
