About this study

Purpose: To develop and test the feasibility of an exercise intervention that combines group walking, activity tracking, and heart rate monitoring, and determine the effectiveness of this intervention on the physical and mental health for individuals with schizophrenia spectrum disorders.

Participants: 14 individuals with schizophrenia spectrum disorders.

Procedures (methods): During the baseline assessment, subjects will be provided with a Fitbit wristband and instructed how to use it. During the first group session, subjects will be taught how to use their heart rate (on the Fitbit) to determine how fast subjects should walk (to achieve the appropriate exercise dosage). Information on proper care, usage, and how to determine the appropriate heart from the watch, which will be used to guide the intensity of the walk will be provided to subjects and reviewed at each group session. For all clinic based group sessions, subjects will arrive at the STEP clinic to meet the entire group and leaders and be reminded of the heart rate (HR) that corresponds with the intensity of that group session. Next, the group will go outside and walk for 30 minutes. At the completion of 30 minutes, everyone will go back into the clinic for water and review of the walk. After the second group session of each week, subjects will receive weekly progress reports of their steps and minutes spent walking the prior week (obtained from Fitbit devices). During this session, subjects will also set individual goals for the upcoming week for both their "intensity walks" and total steps per day.

Read the detailed description

Overview of Procedures: PACE-life will be integrated into the Schizophrenia Treatment and Evaluation Program (STEP) outpatient clinics in Raleigh, NC and Carrboro, NC. The group walks will occur in the surrounding area around the clinics on sidewalks, bike trails, and residential streets. Goal setting groups and all assessments will take place in a conference room at the clinic. Goal-setting will include setting goals for the upcoming week in terms of number of steps as well as how many intensity walks that individuals plan to complete.

Assessments/Measures: The exercise intervention, PACE-Life, will last for 24 weeks and includes both group walks and independent walks (done at a location of the subject's choosing). Participants will be asked to complete assessments at screening, baseline, mid-point, post-test, and 1-month follow-up (approximately 28 weeks total).

At Screening the following measures will be examined: Demographics, the Wechsler Abbreviated Scale of Intelligence (WASI), a licensed physician will complete a medical history and physical exam, Physical Activity Readiness Questionnaire (PAR-Q).

At Baseline, Mid-point, Post-test, and 1-Month Follow-up the following measures will be examined: Demographics, Minutes Spent Walking, the Short Form International Physical Activity Questionnaire (IPAQ), Steps/day, Cardiorespiratory fitness (CRF)- CRF will be measured using the 6-minute walk test (6MWT), Self-determination Basic Needs, the Basic Psychological Need Scale-in General, the Basic Psychological Needs in Exercise Scale (BPNES), the Mini International Neuropsychiatric Interview (MINI) (Baseline Only), Resting Systolic/Diastolic Blood Pressure and resting heart rate (RHR), autonomous motivation will be measured with the Behavioral Regulation in Exercise Questionnaire-2 (BREQ-2), enjoyment of walking will be measured with the Physical Activity Enjoyment Scale (PACES), the UCLA Loneliness Scale, Weight, BMI, and Waist/hip Circumference.

At the conclusion of the open trial, the investigators will administer a brief questionnaire to the subjects regarding satisfaction and acceptability that will have both forced choice and open-ended questions.

Intervention- Groups will occur twice per week for 30 minutes for the entire intervention without changes in frequency and duration. The intensity, however, of both group walks and home-based walks will increase throughout this intervention in a stepwise fashion to create an exercise dose response to maximize impact on CRF.

Fitbits: All participants will be provided a Fitbit that is labeled with a participant number. All Fitbits are paired to a Fitbit account. Data from Fitbit devices can be synced to the corresponding account and accessed through Fitbit.com. Participants will be provided information about their accounts should participants want to look at the data but will be asked not to change any of the settings as the investigators will be using data for tracking steps/day and minutes spent walking.

Study groupRoleWhat they receive
Single Arm Experimental Walking GroupExperimentalThis is a pilot project with one single group that will be evaluated on the adherence to a walking protocol (Exercise Intervention- PACE-Life). Subjects will be walking two times a week under the supervision of the psychiatric clinic. In addition, subjects will be encouraged to add walking on their own on the days when subjects are not exercising under the supervision of the clinic. This pilot will be used to inform the final design of the subsequent randomized clinical trial that will be implemented following this pilot.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Mean Difference in Participant's Total Distance During 6-Minute Walk From Baseline to Week 24

    The 6-minute walk test (6MWT) will be used to measure cardiorespiratory fitness (CRF) during which individuals will be asked to walk continuously for six minutes on a flat, indoor surface around cones (separated by 100 ft). The possible distance range is 400 meters to 650 meters. Higher scores reflect better outcomes (greater physical fitness).

    Measured: Baseline, Post Treatment (24 weeks)

  2. Mean Difference in Participant's Total Distance During 6-Minute Walk From Post Treatment to Week 28

    The 6-minute walk test (6MWT) will be used to measure cardiorespiratory fitness (CRF) during which individuals will be asked to walk continuously for six minutes on a flat, indoor surface around cones (separated by 100 ft). The possible distance range is 400 meters to 650 meters. Higher scores reflect better outcomes (greater physical fitness).

    Measured: Post Treatment (24 weeks), Follow-Up (Up to 28 weeks)

Secondary outcomes (8)
  1. Mean Difference Overall UCLA Loneliness Scale Score

    Mean difference in overall score from Baseline to Post Treatment (24 weeks) and to Follow-Up Visit (up to 28 weeks). The UCLA Loneliness scale is a 20 item scale. Answers are on a 4 point scale with options "I often feel this way," "I sometimes feel this way," "I rarely feel this way," and "I never feel this way." Possible scores range from 20 to 80. Higher scores reflect worse outcomes (greater feelings of loneliness).

    Measured: Up to 28 weeks

  2. Mean Difference Overall PANSS Score

    Mean difference in the overall score from Baseline to Post Treatment (24 weeks) and to Follow-Up Visit (up to 28 weeks). The PANSS is a semi-structured interview using a 30-item scale to evaluate the presence, absence and severity of Positive, Negative and General Psychopathology symptoms of schizophrenia. All 30 items are rated on a 7-point scale (1 = absent; 7 = extreme). Possible scores range from 30 to 210. Higher scores reflect worse outcomes (i.e. greater symptoms of psychosis).

    Measured: Up to 28 weeks

  3. Mean Difference in Body Mass Index (BMI)

    Mean difference in body mass index (BMI) from Baseline to Post Treatment (24 weeks) and to Follow-Up Visit (up to 28 weeks). Higher scores reflect worse outcomes (i.e. greater body mass).

    Measured: Up to 28 weeks

  4. Mean Difference in Diastolic Blood Pressure Change

    Mean difference in diastolic blood pressure change from Baseline to Post Treatment (24 weeks) and to Follow-Up Visit (up to 28 weeks). Normal diastolic blood pressure ranges from ≤ 70 to higher than 120 mmHg. Higher scores reflect worse outcomes (i.e., higher diastolic blood pressure).

    Measured: Up to 28 weeks

  5. Mean Difference in Systolic Blood Pressure Change

    Mean difference in systolic blood pressure change from Baseline to Post Treatment (24 weeks) and to Follow-Up Visit (up to 28 weeks). Normal systolic blood pressure ranges from ≤120 to higher than 140 mmHg. Higher scores reflect worse outcomes (i.e., higher systolic blood pressure).

    Measured: Up to 28 weeks

  6. Mean Difference in Resting Heart Rate Change

    Mean difference in resting heart rate change from Baseline to Post Treatment (24 weeks) and to Follow-Up Visit (up to 28 weeks). Normal heart rate ranges from ≤ 60 to higher than 100. Higher scores reflect worse outcomes (poorer heart condition).

    Measured: Up to 28 weeks

  7. Mean Difference in Waist Circumference

    Mean difference in waist circumference from Baseline to Post Treatment (24 weeks) and to Follow-Up Visit (up to 28 weeks). Normal waist circumference ranges ≤ than 94cm for males and < than 80 for females to higher than 102 cm for males and 88cm for females . Higher scores reflect worse outcomes (i.e. greater waist circumference = disease development risk).

    Measured: Up to 28 weeks

  8. Mean Difference in Weight

    Mean difference in weight from Baseline to Post Treatment (24 weeks) and to Follow-Up Visit (up to 28 weeks). Normal weight ranges from 45 to 130 kilograms . Higher scores reflect worse outcomes (i.e., greater weight).

    Measured: Up to 28 weeks
