Validation of the Orientation to Life Questionnaire in Norwegian Adolescents, Construct Validity Across Samples

In spite of the potential significance of sense of coherence (SOC) for adolescent health and well-being, the past decades have yielded limited progress in investigating the psychometric properties of the most used inventory measuring SOC, The Orientation of Life Questionnaire (OLQ) in adolescents. The present study aimed at investigating the factorial validity and reliability of the Norwegian version of the 13 item OLQ based on two adolescent samples 13–18 years from Norway. Concerning the dimensionality of the OLQ, two measurement models were tested using confirmatory factor analysis; a one-factor model and a three-factor-model. The results showed that a three-factor solution with correlated residual variances between item 2 and item 3 showed the best fit across the two adolescent samples, although five items revealed low factor loadings. The dimensions were highly correlated and showed adequate composite reliability. The present results indicate that the 13 item OLQ has potential as an instrument assessing SOC in adolescents. However, more psychometric testing of the instrument is required in reference to the modified factor structure and the low reliability found on some of the items in OLQ.
