• Conditions: Anxiety; Depression; Distress
• Interventions: Behavioral: Mindfulness Based Cognitive Therapy

• Registration Number: NCT02138513
• Lead Sponsor: Radboud University Medical Center

Brief Summary

Mindfulness-based cognitive therapy has been demonstrated to be effective in reducing anxiety, depression and fatigue in cancer patients. As this intervention can be offered in groups, costs are relatively low. In addition, delivering MBCT online might make the intervention more accessible and cost-effectiveness. However, more information is needed about what treatment works best for which patient.

Therefore, the aim of this study is to investigate clinical and cost-effectiveness of both individual MBCT online and MBCT offered as a group training compared to TAU .

Study design: The design of the study will be a multi-centre, randomised, superiority trial, comparing MBCT online and MBCT offered as a group training with TAU. Participants in the TAU condition will be randomised to one of the treatment conditions after 3 months. Main assessments will take place at baseline (T0), post-treatment (T1), and 3 (T2) and 9 months after post-treatment (T3).

We expect the MBCT conditions to be superior to TAU in terms of improving mindfulness skills, anxiety and depressive compants, psychological well-being, rumination and fear of cancer recurrence. We also expect the MBCT to result in patients returning to work earlier, have a higher work ability and have lower medical care costs, thereby being more cost-effective than TAU.

Primary Outcome Measures

Name	Time	Method
Change from baseline in anxiety and depressive symptoms	0 (baseline), 3 months (post intervention)	Anxiety and depressive symptoms as assessed by the Hospital Anxiety and Depression-scale (HADS). The HADS is a self-report questionnaire that comprises 14 items measuring feelings of generalized fear and depressive symptoms. The HADS is considered a reliable and valid instrument for assessing anxiety and depression in medical patients and is sensitive to change (Herrmann, 1997; Bjelland et al., 2002). This instrument was also validated in a palliative cancer population (Akechi, 2006).

Secondary Outcome Measures

Name	Time	Method
Change from baseline in fear of cancer recurrence	0, 3 (post intervention), 6 (3mo follow-up) and 12 months (9mo follow-up)	Fear of cancer recurrence will be assessed with the Fear of Cancer Recurrence Inventory (FCRI; Simard \& Savard, 2009a; van der Lee et al., 2012).
Change from baseline in mindfulness skills	0, 3 (post intervention), 6 (3mo follow-up) and 12 months (9mo follow-up)	The 39-item Five Facet Mindfulness Questionnaire has been developed as a reliable and valid comprehensive instrument for assessing different aspects of mindfulness. A Dutch 24-item short form of the FFMQ (FFMQ-SF) was developed and assessed in a sample of 376 adults with clinically relevant symptoms of depression and anxiety and cross-validated in an independent sample of patients with fibromyalgia. Confirmatory factor analyses showed good model fit for the five-factor structure of the FFMQ-SF: observing, describing, acting with awareness, nonjudging, and nonreactivity. The FFMQ-SF was related to measures of psychological symptoms, well-being, experiential avoidance, and the personality factors neuroticism and openness to experience.
DSM-IV Axis I mood or anxiety disorders	0, 3 (post intervention), 12 months (9mo follow-up)	DSM IV Axis I psychiatric disorder as diagnosed by a structured interview
Change from baseline in personality assessment	0 (baseline) and 12 months (9mo follow-up)	Personality is measured with the NEO Five Factor Inventory (NEO-FFI, Costa \& McCrae, 1992) which consists of five domains: neuroticism, extraversion, openness, altruism, and conscientiousness.
Working alliance during intervention	week 4 and week 9 during intervention	The Working Alliance Inventory (WAI) is most often used to assess working alliance between participant and healthcare professional. We will use the Dutch translation of the short form (WAI-S, Vervaeke \& Vertommen, 1996), which is closely related to the original scale and also has good psychometric and predictive quality (Busseri \& Tyler, 2003). The WAI-S is a 12 item, self report questionnaire, rated on a 7-point Likert scale (1 = never to 7 = always) with three subscales: 1) agreement between participant and therapist on the goals of the therapy; 2) agreement on the rationale of the therapy addressing the problems of the participant; and 3) the quality of the interpersonal bond between the participant and the therapist.
Change from baseline in healthcare consumption	0, 3 (post intervention), 6 (3mo follow-up) and 12 months (9mo follow-up)	The TIC-P generates quantitative data about direct medical costs and indirect societal costs as a consequence of psychological/psychiatric illnesses.
Change from baseline in rumination	0, 3 (post intervention), 6 (3mo follow-up) and 12 months (9mo follow-up)	The rumination subscale of the RRQ assesses a neurotic self-attentiveness (i.e. recurrent, primarily past-oriented thinking about the self), which is prompted by threats, losses, of injustices to the self. Subjects rate their level of agreement of disagreement on a five-point rating scale (e.g., "I always seem to be rehashing in my mind recent things I've said or done"). There is evidence of good internal consistency (.90) and stability over a 10-month period and convergent validity. The measure in the current study was translated into Dutch using the guidelines of the International Test Commission (Hambleton, 1994). Cronbach's alphas were .88 and .90 in Sample 1, and .90 and .91 in Sample 2, respectively (Luyckx et al., 2008).
Group cohesion during intervention	week 4 and week 9 during intervention	We will examine self-reported individual group cohesion ratings during the MBCT training with a Dutch Group Cohesion Questionnaire that has been used in cancer patients before (May et al., 2008). The GCQ-23 uses 22 items across four scales: the bond with the group as whole, the bond with other members, cooperation within the group and the instrumental value. Each item is rated from 1 (totally disagree) to 6 (totally agree). Internal consistency of all scales was reported to range from adequate to good (0.66-0.88).
Change from baseline in positive mental health	0, 3 (post intervention), 6 (3mo follow-up) and 12 months (9mo follow-up)	The Mental Health Continuum-Short Form (MHC-SF) measures positive mental health and comprises 14 items, representing various feelings of well-being. Respondents rate the frequency of every feeling in the past month on a 6-point Likert scale (never, once or twice a month, about once a week, two or three times a week, almost every day, every day). The MHC-SF contains three subscales: emotional, psychological and social well-being. MHC-SF has shown high internal and moderate test-retest reliability, convergent and discriminant validity.
Change from baseline in health-related quality of life	0, 3 (post intervention), 6 (3mo follow-up) and 12 months (9mo follow-up)	In addition to the EQ-5D, the SF-12 will be administered for explorative purposes for there are indications that the SF-12 is more sensitive for changes in HRQol in populations with less severe morbidity (Johnson and Coons, 1998).
Change in mindfulness skills during intervention	week 2,3,4,5,6,7,8 and 9 of intervention	The Mindful Attention Awareness Scale (MAAS) will be administered before each MBCT session to assess mindful attention in daily life
Change in mood during intervention	week 2,3,4,5,6,7,8 and 9 of intervention	In the current study, positive and negative affect is assessed before each MBCT session using the International Positive and Negative Affect Scale - Short Form. The cross-sample stability, internal reliability, temporal stability, crosscultural factorial invariance, and convergent and criterion-related validities of the I-PANAS-SF were examined and found to be psychometrically acceptable (Thompson, 2007).
Change from baseline in anxiety and depressive symptoms - follow up	0, (baseline) 6 (3mo follow-up) and 12 months (9mo follow-up)	Hospital Anxiety and Depression Scale - anxiety and depressive symptoms at follow up.
