Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from sexual activity | 4 weeks (T1), 8 weeks (T2);three months (T3) and six months (T4) after completion of the 8 weeks intervention | The score change of the Sexual Activity Questionnaire(SAQ).The SAQ consists of 10 items and three subscales. Higher pleasure or discomfort subscale score indicated higher levels of pleasure or discomfort, and habit is a single item (0 'less sexual activity than usual' to 3 'much more sexual activity than usual'). |
| Change from Female sexual function index | 4 weeks (T1), 8 weeks (T2);three months (T3) and six months (T4) after completion of the 8 weeks intervention | The score change of Female Sexual Function Index (FSFI). FSFI consists of 19 items comprising six domains of sexual function (desire, arousal, lubrication, orgasm, satisfaction, and pain). The total score ranges from 0 to 36. Higher score corresponds to better sexual functioning. |
| Change from Sexual distress | 4 weeks (T1), 8 weeks (T2);three months (T3) and six months (T4) after completion of the 8 weeks intervention | The change of The Female Sexual Distress Scale-Revised (FSDS-R).The total score ranges from 0 to 48, and a higher score indicates a higher level of sexual distress. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change from Fatigue | 4 weeks (T1), 8 weeks (T2);three months (T3) and six months (T4) after completion of the 8 weeks intervention | The Brief Fatigue Inventory (BFI) will be used. The total score ranges from 0 to 90. Higher scores on the BFI indicates greater self-reported levels of fatigue. |
| Change from Body Image | 4 weeks (T1), 8 weeks (T2);three months (T3) and six months (T4) after completion of the 8 weeks intervention | Body Image Subscale (BIS) of the European Organization for Research and Treatment of Cancer Quality of Life-Breast Cancer Module (EORTC- QLQ-BR23) will be used. The total score ranges from 4 to 16, and higher score indicates higher level of body image. |
| Change from Quality of life (QOL) | 4 weeks (T1), 8 weeks (T2);three months (T3) and six months (T4) after completion of the 8 weeks intervention | The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core30 (EORTC QLQ-C30) simplified Chinese V3.0 version will be used. The total score ranges from 0 to 100. Higher scores of symptom and financial scales indicates more severe symptoms. |
| Change from Sleep quality | 4 weeks (T1), 8 weeks (T2);three months (T3) and six months (T4) after completion of the 8 weeks intervention | The Pittsburgh Sleep Quality Index (PSQI) will be used. The total score ranges from 0 to 21. Higher scores indicate poorer sleep quality. |
| Change from Anxiety and Depression | 4 weeks (T1), 8 weeks (T2);three months (T3) and six months (T4) after completion of the 8 weeks intervention | The Hospital Anxiety and Depression Scale (HADS) will be used.Higher HADS-D ( ranges from 0-21) or HADS-A ( ranges from 0-21) score correspond to more serious psychological distress |
| Change from Menopausal symptoms | 4 weeks (T1), 8 weeks (T2);three months (T3) and six months (T4) after completion of the 8 weeks intervention | The Endocrine symptom subscale (ESS) of the Endocrine Subscale for The Functional Assessment of Cancer Therapy-Breast (FACT-B ES) will be used. The total score ranges from 0 to 72. Higher score indicates fewer menopausal symptoms |
