After my research on Cognitive Behavioural Play Therapy (which can be found here), I came across two main problems: the target age wasn't appropriate and it was primarily a physical, hands-on therapy process. A similar approach that I found was art therapy, which is used by people of all ages and can be completed through various mediums (including digitally).
Art therapy is the use of artistic methods e.g. painting, drawing, modelling etc. to treat mental health disorders such as:
Aging-related issues
Anxiety
Depression
Eating disorders
Emotional difficulties
Substance use disorder
Family or relationship problems
Medical conditions
Psychological symptoms associated with other medical issues
Post-traumatic stress disorder (PTSD)
Stress
The foundations of this technique are formed from the idea that creative expression can enhance well-being and overall mental health. Art therapy originated as a formal term in the 1940s, though communicating artistically has been practised for thousands of years. Doctors had noticed that patients who were dealing with mental health issues would regularly express their feelings through artwork, ultimately initiating an exploration of how art can be used as a healing strategy.
"According to a 2016 study published in the Journal of the American Art Therapy Association, less than an hour of creative activity can reduce your stress and have a positive effect on your mental health, regardless of artistic experience or talent.
An art therapist may use a variety of art methods, including drawing, painting, sculpture, and collage with clients ranging from young children to older adults.
Clients who have experienced emotional trauma, physical violence, domestic abuse, anxiety, depression, and other psychological issues can benefit from expressing themselves creatively."

A few beneficial examples of combining these two practices together include:
