Evaluating depression anxiety and stress assessment before and during the COVID-19 pandemic using generalisability theory.

The current study investigated the assessment of depression, anxiety, and stress during normal and COVID-19 pandemic conditions. Generalisability theory (G-theory) was applied to examine stable and dynamic aspects of psychological distress and the overall reliability of the Depression, Anxiety and Stress Scales (DASS-21), using data from two independent samples collected on three occasions with 2- to 4-week intervals. The US data (n = 115) was collected before the COVID-19 pandemic, and the New Zealand (NZ) data (n = 114) was obtained during the pandemic.

The Role of Mindfulness and Life Satisfaction in Psychological Distress During the COVID-19 Lockdown in New Zealand: a Quasi-experimental Study.

The goal of this study was to investigate psychological distress during the lockdown in New Zealand.

Methods: We implemented a longitudinal quasi-experimental research design using a sample ( = 81) who completed surveys on mindfulness, satisfaction with life, and mental health indicators at three time-points, separated by at least 2-week intervals.
