Increase in physical activity is associated with an increase in sleep efficiency, but not with improvement in symptoms of PTSD: analysis of longitudinal data in trauma-affected refugees

Table 2 Mean scores at baseline and end of treatment for self-reported PTSD symptoms (HTQ), quality of sleep (PSQI), quality of life (WHO-5), actigraphy-derived activity count (M10) and sleep efficiency (SE)

Rating	Mean score (SD) baseline	Mean score (SD) end of treatment	Difference baseline-end of treatment	p-value difference baseline-end of treatment
Self-reported
HTQ, n = 159	3.14 (0.41)	2.95 (0.62)	-0.18 (0.59)	< 0.0001*
PSQI, n = 154	16.35 (2.69)	14.53 (4.29)	-1.82 (4.27)	< 0.0001*
WHO-5, n = 146	17.25 (16.39)	25.18 (23.07)	7.94 (21.68)	< 0.0001*
Actigraphy measures
M10, n = 54	267.13 (85.65)	268.43 (89.83)	1.30 (63.18)	0.880
SE, n = 55	80.80 (6.88)	79.38 (6.94)	-1.41 (5.09)	0.045*
