The Effects of a Strengths Intervention on Students’ Personal Growth Initiative -
PsyCap as a Mediator
NOW WHAT?
“Active, intentional engagement in the process of personal growth” (Robitschek, 1998, p. 184)
- influences the extent to which someone seeks out and capitalizes on
opportunities to grow (Robitschek et al., 2012)
- predicts environmental exploration and vocational identity in students (Robitschek & Cook, 1999)
- can be developed through interventions that stimulate growth activities(Thoen, & Robitschek, 2013)

RESEARCH DESIGN
Sample: N=98(90)
Master students in their final year
79% female; mean age: 22.9
Help students to identify their strong points & encourage them to develop and use their strengths (based on Quinlan et al., 2012)
- 1 training day
- Groups of 10-14 students
- Various work forms
- Preparations & homework assignments
STRENGTHS INTERVENTION
Personal Growth Initiative Scale PGIS (Robitschek, 1998)
Sample item: ‘I have a specific action plan to help me reach my goals’
Reliability: α0 = .75; α1 = .80.; α2 = .83.; α3 = .83
Psychological Capital
New General Self-efficacy Scale (Chen, Gully, & Eden, 2001)
Life Orientation Test – Revised (LOT-R; Scheier, Carver, & Bridges, 1994)
Brief Resilience Scale (Smith et al., 2008)
State Hope Scale (Snyder et al., 1996)
Reliability: α0 = .88; α1 = .85; α2 = .92; α3 = .91

The strengths training enhances students’ personal growth initiative
� working on strengths might produce personal resources
(PsyCap) that motivate students’ self-development
� It is not just a matter of encouraging young people to develop
themselves, but a matter of encouraging development in the right
area: the area of individual strengths
CONCLUSION
Limitations
• Small sample size
• Missing no-treatment control group
• High work-load during the semester as possible confounding factor
Future Research
• Conduct a similar training with working adults or MBA students
• Investigate the effects of interventions with a combination of working on strengths and weaknesses
