Online Dietary and Resistance Training to Improve Physical Function in Older Cancer Survivors, E-PROOF Trial

Satisfaction of the Delivery Method and Information Provided by Nutrition and Exercise Counseling Sessions

Percentage of participant satisfaction ("satisfied" and "very satisfied") measured by a 5-item Likert-scale questionnaire. Scores range from 1-5, with 5 being the highest score of satisfaction.

Time frame: end-of-intervention, at 12 weeks

Study Accrual Rate

Will be calculated by dividing the number of potential participants that passed screening by the total number of participants started in the study after appropriate informed consent procedures.

Time frame: assessed during the 12 month recruitment period

Study Retention Rate

calculated by dividing the total number of participants initiated by total number of participants in the study. Retention goal for this trial is 80%. If 80% (56/70) of participants are retained at end-of-study, the retention goal for this trial will be achieved. Overall retention rates and associated 95% confidence intervals will be reported.

Time frame: End-of-study, up to 3 months

Study Adherence Rate

Participants were determined to be adherent if they attend \>= 80% of the online intervention sessions. Overall adherence rates and associated 95% confidence intervals were reported.

Time frame: end-of-intervention, at 12 weeks

Grip Strength

Handgrip strength (absolute value at the end of the intervention) was measured in both hands using a hydraulic grip strength dynamometer. This is measured in kgs.

Time frame: end-of-intervention, at 12 weeks

Dietary Quality

Dietary quality was assessed by the National Cancer Institute's Diet History Questionnaire III using the Healthy Eating Index score ranging 0-100, with higher scores meaning higher diet quality. Absolute value at end-of-intervention was assessed using the Healthy Eating Index score.

Time frame: end-of-intervention, at 12 weeks

Percentage of Participants Who Completed Resistance Exercises

Self-reported resistance exercise (% yes) was assessed using the revised version of The Godin-Shephard Leisure-Time Exercise Questionnaire modified to specifically capture self-reported resistance exercise participation. If a participant denoted "yes" to the question: did During a typical 7-Day period (a week), did you participate in resistance exercise for more than 15 minutes during your free time? Percentages denote the percentage of the study subjects who participated in resistance training at end of intervention.

Time frame: end-of-intervention, at 12 weeks

Health-related Quality of Life (HRQoL)

RAND-36 Health Status Measure is comprised of 36 items which automatically create 8 subscales assessing multiple aspects of HRQoL. All scores range from 0-100, with 100 as the highest HRQoL. The main HRQoL subscale reported is the general health HRQoL subscale. Mean scores of general HRQoL for end-of-intervention are reported.

Time frame: end-of-intervention, at 12 weeks

Self-efficacy

Self-efficacy was measured at the end of intervention via a 0-10 confidence scale rating the confidence of making exercise and diet changes in one's life, with 0 meaning not confident, 10 meaning very confident.

Time frame: end-of-intervention, at 12 weeks

Technology Competency

The 8-item eHealth Literacy Scale measured knowledge, comfort, and perceived skills of engaging in eHealth at end-of-intervention. A 5-point Likert scale was used, with possible scores ranging from 8 to 40. Higher scores indicate higher ehealth literacy.

Time frame: end-of-intervention, at 12 weeks
