Final answer:
Irvin Yalom's findings include increased feelings of hope, acceptance of death, and decreased existential anxiety for cancer patients in group therapy, but not decreased sense of meaning. The latter is actually often increased, giving patients a greater sense of purpose during their therapy experience. (option d)
Step-by-step explanation:
Irvin Yalom found that cancer patients who engaged in group therapy experience significant inner changes. However, the option in the question that is NOT one of his findings is D) Decreased sense of meaning. Based on Yalom's findings, many patients often find a greater, not decreased, sense of meaning in their lives as they address existential issues.
In contrast, Kübler-Ross's model, which includes stages such as denial, anger, bargaining, depression, and acceptance, shows that acceptance of death is often a stage individuals reach, reflecting an increased sense of meaning in life.
Moreover, individuals tend to experience decreased existential anxiety as they come to grips with their mortality, which is in line with Yalom's findings of inner changes like increased feelings of hope and acceptance of death. These feelings can act as a buffer against despair and offer a new perspective on life's value, which enhances the therapy experience for many patients. It is also worth noting that some people with strong religious or spiritual beliefs might cope better with the concept of death due to the comfort provided by the hope in an afterlife and community support.
Hence, the answer is option d
