To determine the effects of the Cancer and Living Meaningfully (CALM) Therapy intervention on death anxiety at both 3 and 6 months, compared to baseline. Total scores, subscale scores, and/or t-scores (if applicable) were completed at baseline, month 3 and month 6 and summarized, using a paired t-test from baseline to 6 months at a 5% significance level. The DADDS uses a 15-item scale to measure death anxiety. Scores range from 0-75 and higher scores mean greater distress.

Here are the number of participants with a primary central nervous system tumor (PCNST) eligible for remote Cancer and Living Meaningfully (CALM) Therapy.

Mean accrual rate was assessed from baseline to 6 months.

Compliance is defined as at least 80% of participants completing the outcome measures (e.g., depression, distress, quality of life) at all time points - baseline to 6 months.

Here is the number of participants with a primary central nervous system tumor (PCNST) who experienced serious and/or non-serious adverse events assessed by the Common Terminology Criteria for Adverse Events (CTCAE v5.0) assessed from baseline to 6 months. A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life-threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned.

Here is the proportion of participants who participated in the Remote Cancer and Living Meaningfully (CALM) Therapy and completed the study

Participant satisfaction was measured using the Was It Worth It (WIWI) questionnaire, which is designed to measure a participant's opinion of their participation. WIWI questions are dichotomous (yes/no) and are tailored to be specific to the intervention involved in the study. For the purposes of this study, there were four yes/no questions that ascertain the participants' satisfaction with the CALM intervention.

To demonstrate the short-term effects of the Cancer and Living Meaningfully (CALM) Therapy intervention in change of depressive symptoms using the Patient-Reported Outcomes Measurement Information System (PROMIS) - Depression scale in primary central nervous system tumor (PCNST) participants from baseline to 3 months using a paired t-test from baseline to 6 months at a 5% significance level. PROMIS is an 8-item assessment that measures depressive symptoms within the past 7 days and participants rank symptoms on a scale that includes never, rarely, sometimes, often and always. T-scores range from 0 to 100 with T-score greater than 60 indicating moderate-severe depression.

15/19 participants completed the study and were evaluable for this outcome measure.

For the purposes of this study, there were four yes/no questions that ascertain the participants' satisfaction with the CALM intervention.

14/19 participants were analyzed because 2 did not complete CALM, 2 withdrew from the study and 1 participant did not fill out the satisfaction form.

The a priori threshold for statistical significance was < 0.05. We did not adjust for multiple comparisons as this was exploratory.

We evaluated the same group to determine whether their reported anxiety via the Death and Dying Distress Scale was the same, worse, or better at 6-months compared to baseline.
