Intercorrelations of the Anxiety and Preoccupation About Sleep Questionnaire (APSQ) and Convergent Validity of the Athens Insomnia Scale (AIS) and Generalized Anxiety Disorders (GAD-7)

	ASPQ Total	ASPQ F1	ASPQ F2	AIS	GAD-7
ASPQ Total	–			0.85*	0.69*
ASPQ F1	0.94*	–		0.59*	0.66*
ASPQ F2	0.90*	0.71*	–	0.57*	0.66*

Notes: Anxiety and Preoccupation about Sleep Questionnaire (APSQ) is based on the entire sample n = 523. Convergent validity of the test with Athens Insomnia Scale (AIS) and Generalized Anxiety Disorders (GAD-7) is based on subsample of 80 participants only. APSQ F1 = APSQ Factor 1 (Worries about the consequences of poor sleep). APSQ F2 = APSQ Factor 2 (Worries about the uncontrollability of sleep). *represent p values < 0.001, respectively.
