PURPOSE: Measuring subjective quality of life (QoL) is an important complement to symptom ratings in Internet interventions. The Brunnsviken Brief Quality of life scale (BBQ) was developed as an empirically-derived, freely available and easy-to-use QoL inventory. METHODS: Six life areas important for overall QoL were identified using factor analysis performed on a large dataset of QoL ratings. The BBQ (available in 20 languages) has respondents rating both satisfaction with, and importance of, six life areas, totaling 12 items that are weighted pairwise and summed. The psychometric evaluation was performed using a healthy undergraduate sample (n=163) and a sample seeking treatment for social phobia (n=586). RESULTS: The BBQ showed good internal consistency (α=0.762) and good responsiveness to change (SRM=0.43). Good sensitivity (0.75) and specificity (0.71) was found comparing the clinical and non-clinical groups (AUC=0.797). CONCLUSIONS: The BBQ is a valid and reliable measure of subjective QoL in clinical and non-clinical populations.2016-01-082016-01-082016-01-27Bibliographically approved
