Using factor analysis to test hypothesis

I have 8 variables (different types of reading material): V1, V2, V3, V4, V5, V6, V7 and V8. According to theory variables V1-V5 should represent one Factor (non-scientific reading material) and variables V6-V8 should represent the second Factor (scientific reading material).

Based on the theory I formulated next hypothesis:
H1: There are two different types of reading material (…and not just reading material)

This Factors 1 and 2 are then used in structural equation modeling where Factor 1 and Factor 2 are both dependent (e.g. educated people read more scientific material…) and independent (e.g. people who read scientific material….) variables.


My results:

Rotated Factor matrix (suppressed values below 0.2, rotation Varimax)

..... Factor 1 ...Factor 2
V1......0.48
V2......0.50
V3......0.54
V4......0.53
V5......0.68
V6..................0.66
V7..................0.75
V8..................0.78

KMO (over 0.7 which is OK): 0.76
Bartlet’s test of sphericity (significant): 4319,94 (p=0.000)

Crombach alpha (both over 0.6 which is OK):
Factor 1: 0.69
Factor 2: 0.79

My questions:
1. How can I test my H1?
2. Are KMO, Bartlett’s test and Crombach alpha enough to SUPPORT the hypothesis?
3. What kind of text (explanation) should I write?


THANK YOU!!!!!
Kindest regards,
Igor
