"I can think of several things that motivate me to do a good job. First, and most importantly, is knowing that patients and their family's trust me to care for them. Being able to encourage patients who may otherwise be alone, to get involved with activities and see their happiness when doing so makes my job as an activities aide all worth while."

This question is practically begging you to highlight your positive attributes. So don't give a vague, generic response - it tells them very little about you. Instead, try and use this question as an opportunity to give the interviewer some insight into your character, and use examples where possible.

"I've always been motivated by the challenge of a tough situation. In my last role, I came across a particular patient who refused to participate in any activities. I was told he was 'always gruff and impossible.' I talked with him and was able to find something we had in common, which calmed him down. After the patient saw me make an effort to better understand his situation, he became much more agreeable to my aid. I love facing and overcoming challenges on such a personal level."
