Various mood repair strategies are most commonly used in cognitive therapy. They are commonly assigned as homework by therapists in order to help positively impact individuals who are experiencing dysphoria or depression.[1] However, these tools can also be used for individuals experiencing temporary unwanted moods. Many factors go into the effectiveness of mood repair strategies on an individual ranging from the client's self-esteem[2] to their experience with the strategy being used.[1] Even the way the mood repair strategy is presented (either to avoid negative moods or to pursue positive moods) may have an effect on that strategy's ability to improve mood.[1]
