The Acceptability of Intervention Measure (AIM) is brief and contains 4-items using a 5-point Likert scale (possible scores 4-20), with higher scores indicating greater acceptability of the intervention. Adequate reliability and validity have been reported. Benchmark: at least 75% intervention acceptability, across sites.

The Feasibility of Intervention Measure (FIM) is brief and contains 4-items using a 5-point Likert scale (possible scores 4-20), with higher scores indicating greater feasibility of the intervention. Adequate reliability and validity have been reported. Benchmark: at least 75% intervention feasibility, across sites.

The Intervention Appropriateness Measure (IAM) is brief and contains 4-items using a 5-point Likert scale (possible scores 4-20), with higher scores indicating greater appropriateness of the intervention. Adequate reliability and validity have been reported. Benchmark: at least 75% intervention appropriateness, across sites.

The Diabetes Distress Scale (DSS-17) is a widely used, self-administered scale. The DDS-17 contains 17 items and asks a person about living with diabetes, using a six-point Likert format (1=not a problem, 6=a very serious problem). The DDS-17 contains questions related to emotional burden, physician distress, regimen distress and interpersonal distress. Possible scores range from 17 to 102, with higher scores indicating greater diabetes distress.

The Patient Health Questionnaire-9 (PHQ-9) is a widely used, self-administered scale to screen for depressive symptoms. The PHQ-9 contains 9 items that ask a person about problems that have been bothering them during the past 2 weeks, using a four-point Likert format (0=not at all, 3=nearly every day). Possible scores range from 0 to 27, with higher scores indicating greater severity of depressive symptoms.

The Posttraumatic Stress Scale-Civilian Version (PCL-C) is a self-administered scale that asks a person about problems or stressful life experiences during the past month. The PCL-C contains 17 items using a five-point Likert format (1=not at all, 5=extremely). Possible scores range from 17 to 85, with higher scores indicating greater symptoms associated with posttraumatic stress.

The Diabetes Quality of Life Questionnaire (DQOL) is a self-administered scale that asks a person about their diabetes-related satisfaction, impact and worry. The DQOL contains 64 items using a using a five-point Likert format (satisfaction 1=very satisfied, 5=very dissatisfied; impact 1= no impact, 5=always impacted; worry 1=never worried, 5=always worried). Possible scores range from 64 to 320, with higher scores indicating worse quality of life.

The Perceived Stress Scale (PSS-10) is a widely used, self-administered scale. The PSS-10 contains 10 items and asks a person about situations they may have experienced in the past month as being unpredictable, uncontrollable, and overloaded using a five-point Likert format (0=never, 4=very often). Possible scores range from 0 to 40, with higher scores indicating greater perceived stress.

The Dietary Screener Questionnaire (DSQ) is a 26-item self-administered scale that asks about the frequency of consumption of selected foods and drinks in the past month. The DSQ captures intakes of fruits and vegetables, dairy/calcium, added sugars, whole grains/fiber, red meat, and processed meat. The DSQ uses a scoring algorithm to convert responses to estimates of dietary intake for fruits and vegetables (cup equivalents), dairy (cup equivalents), added sugars (tsp), whole grains (ounce equivalents), fiber (g), and calcium (mg). Responses to the red meat and processed meat questions are as qualitative indicators of intake frequency, but no scoring algorithms were developed for those particular dietary factors.

The Rapid Assessment of Physical Activity (RAPA) questionnaire is a widely used, self-administered scale to assess a person's engagement in physical activity during the week. The RAPA contains 9 yes/no questions. The first 7 questions assess weekly physical activity during free time (RAPA 1). Affirmative responses are reviewed to determine the person's level of physical activity during the week (1=sedentary, 7=active). Possible scores range from 1 to 7, with higher scores indicating greater the level and intensity of the physical activity. The last two questions include strength training and flexibility items (RAPA 2), which are scored separately (0=none, 1=strength training, 2=flexibility, 3=both). Possible scores range from 0 to 3, which indicate if the person is engaging in strength and flexibility exercise during the week.
