Brief summary

In this study, the investigators propose to test the efficacy of a couple-focused, web-based tailored prostate cancer symptom management program, Prostate Cancer Education and Resources for Couples (PERC) in a randomized clinical trial. A two-group (PERC versus National Cancer Institute (NCI) website plus treatment as usual) randomized controlled design will be used, and data will be collected at baseline (T1), 4 (T2), 8 (T3), and 12 months (T4) among 300 patients completing initial treatment for localized prostate cancer and their intimate partners (i.e., 600 participants in total).

Detailed description

This randomized clinical trial aims to test the efficacy of a couple-focused, web-based tailored prostate cancer symptom management program, Prostate Cancer Education and Resources for Couples (PERC). The study participants will include 300 patients completing initial treatment for localized prostate cancer and their intimate partners (i.e., 300 dyads and 600 individuals). After informed consent, we will conduct baseline assessment (T1), randomly assign eligible participants to either PERC or the National Cancer Institute (NCI) website, and then collect data at 4 (T2), 8 (T3), and 12 months (T4) post-T1.

Interventions

BEHAVIORALProstate Cancer Education and Resources for Couples (PERC)

PERC uses mHealth technologies to dramatically increase couples' accessibility to posttreatment supportive care whenever and wherever they feel comfortable accessing it. PERC aims to improve QOL for both patients and partners by enhancing positive appraisals of illness and boosting self-efficacy, social support from multiple sources, and healthy behaviors for symptom self-management at home.

BEHAVIORALusual care plus NCI website

The usual care plus NCI website provides generic information about prostate cancer treatment options, research, causes, and statistics; coping resources that are not prostate cancer-specific; support from non-providers via a toll free phone and LiveHelp Online Chat about cancer-related questions, clinical trials, and quitting smoking.

MeasureTime frameDescription
Change in Quality of Life Over Time as Assessed by Functional Assessment of Cancer Treatment (FACT-G) ScoresBaseline, month 4, 8 and 12The Functional Assessment of Cancer Therapy - General (FACT-G) is used to measure change in quality of life of patient and partner from baseline (T1) to T2 (4 months post-T1), T3 (8-months post-T1), and T4 (12-months post-T1). Change from baseline is the post-Baseline values minus the Baseline value. Functional assessment of Cancer Therapy-General is a 27-item survey which assesses physical, social/family, emotional, and functional well-being on a 5-point Likert scale, with 0 indicating not at all and 4 indicating very much in response to item questions. The total FACT-G score is calculated as the sum of four sub scores including physical, social/family, emotional, and functional well-being. Total scores range between 0-108. Higher scores indicated better well-being. It has also demonstrated sensitivity to change over time.

Higher scores represent fewer bother partners reported and better prostate cancer-related quality of life.
Change in Self-efficacy Scores From Baseline to 4-, 8-, and 12-month Post Baseline as Assessed by the Lewis Cancer Self-Efficacy ScaleBaseline, month 4, 8, and 12The Lewis Cancer Self-Efficacy will be used to measure change in patient and partner feelings of self-efficacy in dealing with the patient's cancer diagnosis and treatment from Baseline (T1) to T2 (4 months post T1), T3 (8-months post-T1), and T4 (12-months post-T1). Change from baseline is the post-Baseline values minus the Baseline value. Patients will rate statements about how confident they feel on a scale from 1 to 10, where higher scores indicate higher self-efficacy.
Change in Informational Support Scores From Baseline to 4-, 8-, and 12-month Post Baseline as Assessed by PROMIS-Informational Support Short FormBaseline, month 4, 8, and 12The Patient-Reported Outcomes Measurement Information System (PROMIS) 8a is a National Institute of Health-funded initiative to develop and validate patient-reported outcomes (PROs) for clinical research and practice. PROMISE is a set of measures that evaluates and monitors physical, mental, and social health. It uses a 5-point Likert scale. The scoring process involved collecting PROMIS data from participants and calculating the PROMIS score as the sum of responses to each question. Then Health Measures Scoring Service was used to calculate the PROMIS T-score - the standardized score. Specifically, PROMIS uses a T-score metric in which 50 is the mean of a relevant reference population and 10 is the standard deviation (SD) of that population (T-scores have a mean of 50 and a standard deviation (SD) of 10). On the T-score metric: A score of 40 is one SD lower than the mean of the reference population; A score of 60 is one SD higher than the mean of the reference population.
Change in Instrumental Support Scores From Baseline to 4-, 8-, and 12-month Post Baseline as Measured by PROMIS Instrumental Support-Short Form 8aBaseline, month 4, 8, and 12The Patient-Reported Outcomes Measurement Information System (PROMIS) 8a is a National Institute of Health-funded initiative to develop and validate patient-reported outcomes (PROs) for clinical research and practice.

Change in Appraisal of Illness Scores From Baseline to 4-, 8-, and 12-month Post Baseline as Measured by Appraisal of Illness ScaleBaseline, month 4, 8, and 12The appraisal of Illness scale is used to measure changes in perception of prostate cancer and related issues among patients and their partners. The Appraisal of Illness scale is a 20-item measure that uses Likert Scales ranging from 1 to 5 (very false to very true). The score range is 1-5. The higher score indicated a better cognitive appraisal of the illness the patient or partner had. The score is calculated by the Prorated mean scale scores. The formula is prorated scale score =\[SUM OF ITEM SCORES\]x\[N OF ITEMS IN SCALE\]/\[N OF ITEMS ANSWERED\]. Measurements were performed at baseline (T1) to T2 (4 months post T1), T3 (8-months post-T1), and T4 (12-months post-T1). Change from baseline is the post-baseline values minus the baseline value. Higher scores indicate better support.
Change in Expanded Prostate Cancer Index Composite Short Form (EPIC 26) Urine Symptom Score (Partners Only)Baseline, month 4, 8, and 12Urinary symptom scores change by time were measured using caregiver assessed urinary symptoms subscale of the 4-item caregiver version of the Expanded Prostate Cancer Index Composite Short Form which is designed to assess how much of a bother/burden patients' prostate cancer symptoms were for the partners themselves. EPIC-caregiver was used Baseline (T1) to T2 (4 months post-T1), T3 (8 months post-T1), and T4 (12 months post-T1). The partner reported how patients' urinary and bowel, sexual, and hormonal symptoms bothered the caregivers. The score range is 0-100. Higher scores represent fewer bother partners reported and better prostate cancer-related quality of life.

Change in Depression From Baseline to 4-, 8-, and 12-month Post Baseline as Assessed by PROMIS-Emotional Distress-Depression

PROMIS-Emotional Distress-Depression Short From 8b is used to measure the change in depression scores among patients from Baseline (T1) to T2 (4 months post T1), T3 (8-months post-T1), and T4 (12-months post-T1). Required by the PROMIS scoring instrument, for all PROMIS measurements, total raw scores are translated into T scores for each participant, where the T score rescales the raw score into a standardized T score with a mean of 50 and a standard deviation (SD) of 10. The depression sub-scale of the PROMIS item bank measures the extent to which participants experience depressive symptoms in the past 7 days using a 5-point Likert scale (1=never; 2=rarely; 3=sometimes; 4=often; and 5=always) with the total scores range from 24.7 to 63.5 with higher scores indicate greater depressive symptoms.

Change in Expanded Prostate Cancer Index Composite Short Form (EPIC 26) Bowel Symptom (Partners Only)

Bowel symptom scores change by time were measured using caregiver-assessed bowel symptoms subscale of the 4-item caregiver version of the Expanded Prostate Cancer Index Composite Short Form which is designed to assess how much of a bother/burden patients' prostate cancer symptoms were for the partners themselves. EPIC-caregiver was used Baseline (T1) to T2 (4 months post T1), T3 (8 months post-T1), and T4 (12 months post-T1). The partner reported how patients' urinary and bowel, sexual, and hormonal symptoms bothered the caregivers. The score range is 0-100. Higher scores represent fewer bother partners reported and better prostate cancer-related quality of life.

Change in Fatigue From Baseline to 4-, 8-, and 12-month Post Baseline as Assessed by The Functional Assessment of Cancer Therapy - General (FACT-G) Scores

FACT-G is used to measure the change in the quality of life of patients and partners from baseline (T1) to T2 (4 months post-T1), T3 (8 months post-T1), and T4 (12 months post-T1). Change from baseline is the post-baseline values minus the Baseline value. Functional Assessment of Cancer Therapy-General is a 27-item survey that assesses physical, social/family, emotional, and functional well-being on a 5-point Likert scale, with 0 indicating not at all and 4 indicating very much in response to item questions. The total FACT-G score is calculated as the sum of four sub-scores including physical, social/family, emotional, and functional well-being. Total scores range between 0-108. Higher scores indicated better well-being. It has also demonstrated sensitivity to change over time.

Change in Informational Support Scores From Baseline to 4-, 8-, and 12-month Post Baseline as Assessed by PROMIS-Informational Support Short Form

The Patient-Reported Outcomes Measurement Information System (PROMIS) 8a is a National Institute of Health-funded initiative to develop and validate patient-reported outcomes (PROs) for clinical research and practice. PROMISE is a set of measures that evaluates and monitors physical, mental, and social health. It uses a 5-point Likert scale. The scoring process involved collecting PROMIS data from participants and calculating the PROMIS score as the sum of responses to each question. Then Health Measures Scoring Service was used to calculate the PROMIS T-score - the standardized score. Specifically, PROMIS uses a T-score metric in which 50 is the mean of a relevant reference population and 10 is the standard deviation (SD) of that population (T-scores have a mean of 50 and a standard deviation (SD) of 10). On the T-score metric: A score of 40 is one SD lower than the mean of the reference population; A score of 60 is one SD higher than the mean of the reference population.

Change in Pain From Baseline to 4-, 8-, and 12-month Post Baseline as Assessed by Patient-Reported Outcome Measurement Information System (PROMIS) Scores

PROMIS Pain Interference - Short Form 6b is used to measure change in Pain Interference among patients and their partners from Baseline (T1) to T2 (4 months post-T1), T3 (8-mon post-T1), and T4 (12-mon post-T1). Required by PROMIS scoring instrument, for all PROMS measurements, total raw scores are translated into T scores for each participant, where the T score rescales the raw score into a standardized T score with a mean of 50 and a standard deviation (SD) of 10. The pain measures the extent to which patients experience problems with pain over the past 7 days using a 5-point Likert scale. Higher scores reflect greater Pain Interference. The score value ranges between 41-78.3.

Time frame: Baseline, month 4, 8, and 12

Population: The number reported in the results is based on participants.

Change in Self-efficacy Scores From Baseline to 4-, 8-, and 12-month Post Baseline as Assessed by the Lewis Cancer Self-Efficacy Scale

The Lewis Cancer Self-Efficacy will be used to measure change in patient and partner feelings of self-efficacy in dealing with the patient's cancer diagnosis and treatment from Baseline (T1) to T2 (4 months post T1), T3 (8-months post-T1), and T4 (12-months post-T1). Change from baseline is the post-Baseline values minus the Baseline value. Patients will rate statements about how confident they feel on a scale from 1 to 10, where higher scores indicate higher self-efficacy.

Time frame: Baseline, month 4, 8, and 12

Population: Subjects completed the study assessment at a time point. The number reported participant flow is the dyad with the intention-to-treat principle. Each dyad contains one patient and one partner.

Change in Sleep Disturbance From Baseline to 4-, 8-, and 12-month Post Baseline as Assessed by PROMIS Scores

PROMIS Sleep Disturbance Short Form 8b is used to examine change in sleep quality of patients and their partners from Baseline (T1) to T2 (4 months post T1), T3 (8-months post-T1), and T4 (12-months post-T1). Required by the PROMIS scoring instrument, for all PROMS measurements, total raw scores are translated into T scores for each participant, where the T score rescales the raw score into a standardized T score with a mean of 50 and a standard deviation (SD) of 10. The sleep disturbance sub-scale measured the extent to which participants experienced sleep disturbance over the past 7 days using a 5-point Likert scale. Higher scores reflect greater sleep disturbance. Score value ranges between 28.9-76.5.
