Background

There is a paucity of research to provide unique intervention support related to integrative and sustainable personal strengths based on positive psychology, career psychology, and behavioral economics. In addition, there are few reference scales for this purpose, so the development of a scale for intervention support has been conducted

Aims

The purpose of the present study was to develop the Brief Sustainable Strength Skills Scale (BSSSS: B4S) and to develop a scale to explore what are the skills to sustainably demonstrate strengths.

Method

The reliability and validity of B4S to be developed will be tested using classical test theory, item response theory and correlation analysis. The B4S was developed using examples from Strength based on theories of Positive Psychology, Sustainability and Behavioural economics and Career Psychology.

The B4S (Total 30 items) has 5 subscales; Relationship skills (8 items),Inquiry skills (8 items), Flexibility skills (6 items), Special skills (5 items), Patience skills (3 items).

Results

In the study (N=11465, Mean age= 26, SD=10), participants’ data was subjected to the exploratory and confirmatory factor analyses and correlation analysis.

It showed 5 factors, indicating that the composite model fit the data well (TLI =.89, RMSEA = .056). 

Conclusion

The study found sufficient concurrent validity between the B4S and Big Five Personality plus (Tokuyoshi, 2017), Subjective Happiness Scale (Lyubomirsky & Lepper,1999).
