Brief Summary

Development and evaluation of an online intervention addressing sexual functioning in gay and bisexual men (GBM) after prostate cancer treatment.

Detailed Description

This study advances research in three areas.

First, prostate cancer is the second most common cancer among gay, bisexual, and other men who have sex with men with documented disparities, yet it is severely under-researched. Because gay sex differs from vaginal sex, physiologically; the results from 614 studies focused on heterosexual men likely do not generalize to gay and bisexual men(GBM) with prostate cancer. There have been no rehabilitation studies specific to GBM survivors of prostate cancer, so clinicians have no relevant studies to inform best practice with their GBM patients.

Second, most prostate cancer studies have tested one or rehabilitation components. The investigators will conduct the first treatment study of a state of clinical practice comprehensive rehabilitation program on GBM's quality of life, including on both urinary and sexual function and bother measures.

Third, almost all prostate cancer studies have focused on men recently treated for prostate cancer.

The long-term objective of this research is to improve the health of gay and bisexual survivors of Prostate cancer and to provide an evidence base for rehabilitation. The Investigators will develop an online rehabilitation program tailored for GBM that addresses both the sexual and urinary effects of prostate cancer treatment. In addition, The Investigators will conduct a comparative recruitment study to identify best methods to recruit 450 GBM with Prostate cancer.

Finally, the Investigators will evaluate the effects of the tailored rehabilitation program on sexual and urinary outcomes. The Investigators will conduct a 24 month, randomized controlled trial of structured rehabilitation versus routine care. The Investigators will study both GBM recently treated (last 2 years) and GBM post-treatment (2+ years), using a stratified design. This randomized control trial will identify whether a structured rehabilitation program is effective in addressing the major sexual and urinary problems caused by Prostate cancer treatment. As the first treatment study to focus on GBM with Prostate cancer (and also on oral and anal sex), it addresses a long-standing health disparity.

The study has high potential to transform rehabilitation for GBM with Prostate cancer, provide a critical evidence base for clinicians, and inform rehabilitation outcomes for all Prostate cancer survivors.

• Sex: Male
• Target Recruitment: 403

Inclusion Criteria

1. Gay or Bisexual Men, defined as a biological adult male, who by self-report, has had sex with a man.
2. Treated for prostate cancer, defined as (i) having been diagnosed with prostate cancer and measured by being able to report a Prostate- Specific Antigen and Gleason score; and (ii) treated by radical prostatectomy, radiation or systemically.

Arm && Interventions

Group	Intervention	Description
Intervention Evaluation Test Group	Restore Rehabilitation Program	We will evaluate the effects of an educational, tailored, online rehabilitation program addressing sexual and urinary outcomes after treatment by surveying at 3 month intervals
Intervention Evaluation Control Group	Control	Surveys at 3 month intervals

Primary Outcome Measures

Name	Time	Method
Urinary Function Scores	24 months	The Urinary Function domain of the Expanded Prostate Cancer Index Composite (EPIC-50) scale was used to assess the frequency of urinary symptoms. Scores range from 0 to 100, with higher scores indicating less frequency of urinary symptoms.
Sexual Functioning Scores	24 months	The Sexual Functioning domain of the Expanded Prostate Cancer Index Composite (EPIC-50) scale was used to assess the frequency of sexual functioning symptoms. Scores range from 0 to 100, with higher scores indicating less frequency of sexual functioning symptoms.
Intervention Acceptability	3-month follow-up	Acceptability was measured by how much intervention group participants would recommend the intervention to a friend (if he had prostate cancer). This single Likert-type item has five response options from 1=strongly agree to 5= strongly disagree. Acceptability will be measured by adding those who answered 1=strongly agree or 2=agree on this item.
Intervention Feasibility	3-month follow-up	Feasibility will be measured by monitoring the number of intervention participants who could access the intervention webpage at least once within the first three months of the study.
