The primary aim of this study is to examine the effects of a mindfulness-based stress reduction training program, delivered in individual web-based sessions, among breast cancer patients. The objectives are to study and answer questions regarding effects of the such training in a randomized controlled trial including the following outcome measures: physical and mental health status, perceived stress, post-traumatic stress symptoms, psychological well-being, and sleep quality. In addition to the primary aim, the investigators plan to explore potential mechanisms through which mindfulness training lead to improvement in perceived stress, well-being and sleep-quality. This will be studied by mediational analyses.

    Perceived stress as measured with the Perceived stress scale (PSS) and the Intrusion of event scale revised (IES-R) before and after intervention

  • Change in Psychological Well-Being [ Time Frame: Baseline to 8 week follow-up change ] [ Designated as safety issue: No ]
    Psychological Well-Being as measured with the Psychological Well-Being (PWB) scale by C Ryff; a questionnaire measuring six dimensions of psychological well-being: environmental mastery; self-acceptance; positive relations with others; purpose in life; personal growth; and autonomy.

    Sleep quality as measured with the Karolinska Sleep Questionnaire (KSQ) a 13-item questionnaire assessing sleep-time and quality as well as perceived satisfaction with sleep, sleepiness and sleep disturbance.

Secondary Outcome Measures:
  • Change in Perceived stress [ Time Frame: Change from baseline to 12 months follow-up ] [ Designated as safety issue: No ]

Other Outcome Measures:
  • Sickness-absence for work [ Time Frame: At 24 months follow-up ] [ Designated as safety issue: No ]
    Gorup differences in sickness-absence from work as measured in national population registries

  • All cause morbidity [ Time Frame: At 24 months follow-up ] [ Designated as safety issue: No ]
    Group differences in all cause morbidity as measured in national registries

  • All cause mortality [ Time Frame: At 24 months follow-up ] [ Designated as safety issue: No ]
    Group differences in all cause mortality as measured in national registries.
