Exploring cutoff points and measurement invariance of the Brunnsviken brief quality of life inventory.

ABSTRACT:

Introduction

Quality of life (QoL) can be defined as the goodness of life, beyond simply absence of disease or functional impairments, self-rating scales of which capture valuable information beyond change in primary outcomes. This study (n = 3,384) validated the Brunnsviken Brief Quality of Life Inventory (BBQ) across divergent groups by evaluating its measurement invariance (MI). We hypothesized measurement invariance for the BBQ across age groups, genders, depression, and anxiety severity. Potential cutoff points for the BBQ were also explored.

Method

Confirmatory factor analysis (CFA) models were fit to sample data obtained from an ongoing study on transdiagnostic internet-based treatment modules. Parameters were successively constrained to assess configural, metr
