General anxiety was measured using the two-item Generalized Anxiety Disorder scale and a cut-off of 3 was used to define moderate-to-severe anxiety symptoms. Depression was measured using the 9-item Physician Health Questionnaire and was defined using a cut-off of 10 to denote moderate-to-severe levels of depression. Insomnia was defined using a cut-off score equal or less than 16 on the Sleep Condition Indicator. Insomnia was also defined using the four main criteria for insomnia disorder as per Diagnostic and Statistical Manual, fifth edition
