All of these statements are true regarding estimates of alternate- and parallel-forms reliability. Two test administrations with the same group are required to estimate the reliability of alternate-forms. Test scores may be affected by factors such as motivation, fatigue, or intervening events like practice, learning, or therapy, leading to lower reliability estimates. Item sampling is a potential source of error variance that can affect both parallel- and alternate-forms reliability estimates.
