Mental disorders are among the most common causes of disability globally. Given the high prevalence of mental disorders (57.0%) in Azores islands (Portugal), local primary health care (PHC) services should encourage the implementation of complementary interventions for prevention of this type of disorders. New approaches, such as mind-body therapies, have been studied and recommended for prevention and treatment of numerous chronic diseases, particularly mental disorders. This study aims to evaluate the feasibility and effectiveness of a 6-months mind-body therapies (yoga, qigong and pilates), in users of Ponta Delgada Health Center (PDHC) with perceived distress, compared to a waiting list control.
VIVE mind will be a pragmatic, single-center, randomized controlled trial. Users of PDHC with perceived distress (PSS-10), aged 18 years or over, will be recruited and randomly assigned into experimental and waiting list control group, in a 1:1 ratio. The recruitment of participants will be held in PDHC by health professional (e.g., family medicine doctors, nurses, nutritionists, psychologists, etc). After signed informed consent and baseline measures, experimental group will participate in body-mind sessions (yoga, qigong or pilates), oriented by certified instructors, during 6-months. Each participant should attend only one of the therapies, in order to guarantee a differentiated evaluation. In every session, it will be evaluated the participants' adherence and theirs perceived enjoyment and exertion. The other outcomes (primary and secondary) will be analyzed through a face-to-face contact, in three different moments: baseline (T0), post-intervention (at month 6, T1) and 6-month follow-up (at month 12, T2). The control group will not participate in any specific intervention, but will receive the body-mind intervention after the experimental period. An intention-to-treat and per protocol analysis will be performed to analyze intervention effectiveness and efficacy.

Change in perceived stress
Perceived Stress Scale (PSS 10), validated for portuguese population, is a self-report scale with 10 items on daily hassles and the current feeling of being able to handle problems that need to be addressed. It is a five-point Likert scale ranging from 0 (never) to 4 (very often). This questionnaire is widely used to measure perceived stress and has adequate internal and test-retest reliability.
Time frame: T0, baseline; T1, post-intervention (at month 6); and T2, 6-month follow-up (at month 12)
Adherence to the mind-body sessions
Proportion of adherence to the mind-body sessions will be calculated by the average of adherence of each participant. The adherence of each participant will be quantified by the relationship between the sessions attended and the total number of sessions scheduled over the 6 months.
Time frame: Up to 6 months
Perceived enjoyment
Perceived enjoyment of the mind-body sessions will be measured biweekly by a scale rated from 1 (very unpleasant) to 5 (very enjoyable).
Time frame: Up to 6 months
Perceived exertion
Perception exertion of mind-body sessions will be measured biweekly by the modified Borg scale. In this instrument, 11 items are evaluated, with a score of 0 to 10 points, where 0 equals the minimum effort and 10 the maximum that they can perform.
Time frame: Up to 6 months
Participants' satisfaction
Participant's satisfaction levels will be measured by 10-items questionnaire, on a five point Likert scale from 1 (displeased) to 5 (very satisfied).
Time frame: T1, Post-intervention (at month 6)
Change in hand grip strength
Hand grip strength will be evaluated while the participant is in a sitting position with shoulders adducted and neutrally rotated, elbow flexed at 90°, forearm in neutral and wrist between 0 and 30° of extension. The test will be repeated 3 times with the dominant hand, and maximum reading will be taken.
Time frame: T0, baseline; T1, post-intervention (at month 6); and T2, 6-month follow-up (at month 12)
Change in body mass index (BMI)
Weight (kilograms) and height (meters) will be combined to report BMI in kg/m\^2.
Time frame: T0, baseline; T1, post-intervention (at month 6); and T2, 6-month follow-up (at month 12)
Change in waist circumference
Waist circumference in centimeters.
Time frame: T0, baseline; T1, post-intervention (at month 6); and T2, 6-month follow-up (at month 12)
Change in body fat
Measured by bioelectrical impedance analysis.
Time frame: T0, baseline; T1, post-intervention (at month 6); and T2, 6-month follow-up (at month 12)
Change in body lean mass
Measured by bioelectrical impedance analysis.
Time frame: T0, baseline; T1, post-intervention (at month 6); and T2, 6-month follow-up (at month 12)
Change in systolic and diastolic blood pressure
Resting systolic blood pressure.
Time frame: T0, baseline; T1, post-intervention (at month 6); and T2, 6-month follow-up (at month 12)
Change in fast blood glycemia
Fast blood glycemia (mg/dL).
Time frame: T0, baseline; T1, post-intervention (at month 6); and T2, 6-month follow-up (at month 12)
Change in HbA1c
HbA1c (%) reflects the average plasma glucose over the previous 8 to 12 weeks.
Time frame: T0, baseline; T1, post-intervention (at month 6); and T2, 6-month follow-up (at month 12)
Change in blood lipid profile
Total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides.
Time frame: T0, baseline; T1, post-intervention (at month 6); and T2, 6-month follow-up (at month 12)
Change in chronic pain
Brief Pain Inventory (BPI) will assess the average pain at rest, using a numerical (0-10) rating scale on the BPI Short Form. A higher score indicates worse pain (10 is "worst pain imaginable") and zero indicates 'no pain at all'.
Time frame: T0, baseline; T1, post-intervention (at month 6); and T2, 6-month follow-up (at month 12)
Change in nicotine dependence
Fagerström Test for Nicotine Dependence (FTND) will be applied only in smokers participants. FTND is a 6-item self-report measure of nicotine dependence derived from the Fagerström Tolerance Questionnaire, which comprises yes/no options (scored from 0 to 1) and multiple-choice items (scored from 0 to 3). The items are summed to yield a total score of 0-10. The higher the total Fagerström score, the more intense is the patient's physical dependence on nicotine.
Time frame: T0, baseline; T1, post-intervention (at month 6); and T2, 6-month follow-up (at month 12)
Change in analgesic and psychotropic medication dependence
Number of analgesic and psychotropic pills ingested per day.
Time frame: T0, baseline; T1, post-intervention (at month 6); and T2, 6-month follow-up (at month 12)
Change in health-related quality of life
The health-related quality of life questionaire EQ-5D-5L is a standardised self-report measure of health status developed by the EuroQol Group. It consists of the descriptive system and the EQ Visual Analogue scale. The descriptive system comprises 5 dimensions, namely mobility, self care, usual activities, pain/discomfort, anxiety/depression.
Time frame: T0, baseline; T1, post-intervention (at month 6); and T2, 6-month follow-up (at month 12)
Change in psychological distress
Depression, anxiety stress scale-21 (DASS-21) consists of three 7-item subscales: depression, anxiety, and stress. Participants indicate how much each of 21 items applies to them over the past week on a scale from 0 (did not apply to me at all) to 3 (applied to me very much, or most of the time). This scale has good psychometric properties in both clinical and non-clinical samples. Also, this scale reliably distinguishes between symptoms of anxiety (panic/worry), stress (tension/agitation) and depression (low mood/anhedonia), which are highly comorbid.
Time frame: T0, baseline; T1, post-intervention (at month 6); and T2, 6-month follow-up (at month 12)
Change in mental well-being
Warwick-Edinburgh Mental Well-being Scale (WEMWBS) is a 14-item scale, validated and self-report instrument used to assess mental wellbeing in general population. Possible scores range from range from 14-70, with higher scores indicating higher mental well-being.
Time frame: T0, baseline; T1, post-intervention (at month 6); and T2, 6-month follow-up (at month 12)
