The simple answer is, no.
In Ellen White's statements regarding the Salvation Army, she clearly indicates that "we are not to imitate and fall in with Salvation Army methods" because "this is not the work that the Lord has given us to do." This was not a condemnation, however. She continued, "Neither is it our work to condemn them and speak harsh words against them. There are precious, self-sacrificing souls in the Salvation Army. We are to treat them kindly. There are in the Army honest souls, who are sincerely serving the Lord and who will see greater light, advancing to the acceptance of all truth."
Ellen White then stated, "The Salvation Army workers are trying to save the neglected, downtrodden ones." If someone stopped reading here, they might assume that Ellen White suggested that "trying to save the neglected, downtrodden ones" equaled the "Salvation Army methods" that Adventists are not to imitate. This is not, however, Ellen White's point (or even a legitimate association of terms and concepts--i.e. a stated action is not the same thing as method because a stated action does not explain "how"). Immediately after she stated what Salvation Army workers were trying to do, she imperatively wrote, "Discourage them not. Let them do that class of work by their own methods and in their own way. But the Lord has plainly pointed out the work that Seventh-day Adventists are to do." (Ellen G. White, 8T, 184.3)
