Do not sacrifice construct validity at the altar of internal consistency reliability. Although this is good advice regardless of whether the measures are reflective or formative, it is particularly important to remember when your construct has formative measures, because formative indicator measurement models do not imply high level of internal consistency reliability (Bollen and Lenox 1991). Therefore, when your measures are formative, it is important to resist the temptation to delete items as a means of improving Cronbach’s alpha (internal consistency reliability).
