Brief Summary

Antidepressant-induced sexual dysfunction (AISD) affects the majority of women taking antidepressants and reduces medication compliance: however there is a paucity of evidence-based strategies for the management of this condition. Mindfulness-based cognitive therapy (MBCT) has been shown to be effective in the treatment of non-antidepressant-induced sexual dysfunction and may be beneficial in the treatment of AISD. The investigators propose a randomized, controlled, proof-of-principle trial to establish preliminary evidence of efficacy of MBCT in AISD and to inform the design of a larger trial to evaluate its effectiveness

Detailed Description

The investigators propose a randomized, controlled, proof-of-principle trial to establish preliminary evidence of efficacy of MBCT in AISD and to inform the design of a larger trial to evaluate its effectiveness.

2. Objectives

1. To provide preliminary evidence of efficacy of MBCT in the management of AISD.

2. To establish the feasibility of conducting a larger RCT of MBCT in AISD by assessing recruitment, attendance and retention rates.

3. To determine the minimal clinically important difference (MCID) for the Changes in Sexual Functioning Questionnaire (CSFQ-14) and the Female Sexual Function Index (FSFI).

4. To gain initial estimates of variability for sample size calculation for future trials of interventions in this patient population.

Study design: Randomized, controlled, parallel-group trial. There will be two treatments: a mindfulness-based group intervention and a wait-list control. Randomization will be 2:1 (MBCT: WLC). This will be an open-label single center study.

Procedures: Ethics approval will be obtained from the University of British Columbia (UBC) Clinical Research Ethics Board (CREB). Upon referral to the UBC sexual medicine clinic, women are assessed by a clinician with expertise in sexual medicine. Those diagnosed with AISD, and deemed as likely eligible, are informed about the study and invited to meet with the study coordinator who will assess study criteria and provide more detail about the study procedures. If the patient agrees to participation, she will first read the consent form and accept it. The coordinator will then email her a direct link to the online survey. Upon accessing the link, she will then be routed to the online questionnaire.

Study Groups

mindfulness-based cognitive therapy

The practice of mindfulness will be followed plus the basics of cognitive therapy given in small group format.

Group Type: ACTIVE_COMPARATOR

mindfulness-based cognitive therapy

Intervention Type: BEHAVIORAL

Six two-hour small group sessions (6-9 participants) will be administered over 8 weeks focusing on MBCT. The intervention follows a written protocol to ensure fidelity of delivery. Participants will receive detailed manuals summarizing session content and home assignments (HAs), including mindfulness practices, audio versions of which will be available on an internet link.

waitlist

Women diagnosed with AISD randomised to wait list will receive no active treatment during the trial period.

Group Type: NO_INTERVENTION

No interventions assigned to this group

Eligibility Criteria

Inclusion Criteria

• participants need to be:

1. referred to the Sexual Medicine Clinic

2. women 19 years of age or older

3. fulfilling the DSM-5 criteria for clinical diagnosis of AISD for at least 4 weeks, confirmed by Changes in Sexual Functioning Questionnaire (CSFQ-14) total score of 41 or below

4. on a therapeutic dose of antidepressant for at least 8 weeks and on a stable dose for at least 4 weeks

5. in clinical remission from depression and/or anxiety, confirmed by a Patient Health Questionnaire (PHQ-9) score of less than 5, and a Generalized Anxiety Disorder-7 (GAD-7) score of less than 10, respectively

6. willing to commit to adhere to their antidepressant regimen for the duration of the trial (20 weeks) unless medically contraindicated

7. willing to commit to attend to all group sessions, homework assignments, and questionnaires

8. the referring physician commits to continued provision of mental health care throughout the study

Exclusion Criteria

1. history of SD prior to being started on current antidepressant except SD secondary to clinical depression, or AISD

2. chronic pain with intercourse not relieved with lubricants

3. primary psychiatric disorder other than a depressive or anxiety disorder

4. alcohol/substance abuse

5. general medical illnesses known to impair sexual function including but not limited to cancer, neurological, endocrine, renal, and cardiovascular conditions

6. non-antidepressant medication induced SD (70)

7. receiving other concurrent pharmacological or psychological interventions for SD

8. positive screen for borderline personality disorder, due to the high prevalence of sexual difficulties (70, 71), and the potential destabilizing effect of mindfulness meditation in those affected (72)

9. previous formal practice of mindfulness meditation.
