After losing the client's father in a car accident, a client has started practicing effective coping strategies. according to horowitz’s stages of loss and adaptation, which stage is this indicative of?

Working Through. Psychiatrist Mardi Horowitz divides the process of normal grief into "stages of loss and adaptation". During the "working through", people think about and feel their loss, but also start to figure out new ways to manage it (new ways of managing might include making preparations), engaging in new projects for example. As time goes by, the movement between not thinking about the loss and thinking about the loss tends to slow down (becomes less pronounced).
