The Personal Self-Concept Questionnaire (PSQ) measures self-concept based on responses to 18 items, which are grouped into four categories: Self-fulfilment, Autonomy, Honesty, and Emotional self-concept.
The PSQ is a Likert-type scale with five response options ranging from totally disagree to totally agree.
Reliability and Validity
In the first study, alpha = .85 and in study two, .83.
Data analysis supported a four-dimensional model (see the categories above). Positive correlations with other self-concept measures were significant.
The authors estimated it took about 10 minutes to complete the PSQ.
Their first study included people ages 12 to 36 (n = 506). In the second study, ages were 15 to 65 (n = 1135).
AvailabilityThe PSQ items can be found in the Goñi et al. (2011) article (see the reference below). The 18-items can be found in Table 1 on page 512. Notice the 4-items eliminated from the 22 item measure used in the first study.
