The 21 item scale has 14 items that are somatic and 7 items that reflect anxiety and panic. Each item scores the severity as 0 (not at all) to 3 (severely). Common cut-points are 0-9 = normal; 10-18 = mild/moderate anxiety; 19-29 = moderate anxiety, and 30-63 = severe anxiety.
- Generalized Anxiety Disorder 7-Item Scale (GAD7)
A self-reported anxiety scale based on DSM diagnostic criteria. The severity of each symptom is rated from 0 (Not at all) to 3 (nearly every day) for the past two weeks. The GAD-7 has seven items with a total score of 0-21. Common cut-points are: 0-4 (minimal anxiety), 5-9 (mild anxiety), 10-14 (moderate anxiety), and 15+ (severe anxiety).
- Geriatric Anxiety Inventory (GAI)
The Geriatric Anxiety Inventory (GAI) is a brief, 20-item measure of common symptoms of anxiety in older adults across different settings. Respondents indicate whether they agree or disagree with each of the items. The number of "agree" responses is summed to generate a total score with higher scores indicating higher anxiety.
- Geriatric Mental State Examination (GMSE)
The Geriatric Mental State Examination (GMSE) is a semi-structured clinical interview to assess mental health in older adults. Symptoms are organized into 8 syndrome clusters and interviewers provide a confidence level for each syndrome from 0 (no symptoms) to 5 (very severely affected). A rating of 3 or higher in a cluster indicates a diagnosis. Originally 541 items, the interview has been shortened so that it could be completed in 20-50 minutes.

The Goldberg Anxiety and Depression Scale is an 18-item, self-report questionnaire measuring symptoms of depression and anxiety experienced in the past month. Respondents indicate "Yes" (1) or "No" for each of the symptom questions. Responses for the anxiety and depression scales respectively are summed to generate a score between 0-9. For both the anxiety and depression scales, if respondents indicate "Yes" for any of the first four items, then the interviewer must ask the remaining five items.

DBS-CG can be used as an outcome measure to assess the effect of interventions to reduce dementia caregiver burden. It is a composite measure based on the Modified Caregiver Strain Index, Neuropsychiatric Inventory Questionnaire Distress Scale, and Patient Health Questionnaire (PHQ-9).
- Modified Caregiver Strain Index (MCSI)
The Modified Caregiver Strain Index builds off the original 13-item CSI and can be used to measure caregiver strain as it relates to long-term caregiving situations and experiences. Respondents indicate "Yes, on a regular basis" (2); "Yes, sometimes" (1); or "No" (0) for each of the 13-items. Scores are summed with higher scores representing higher caregiver strain.
- Positive Aspects of Caregiving (PAC) Scale for Dementia
An 11-item scale used to assess caregivers of people with dementia. Caregiver respondents indicate on a 0 to 4-point scale their level of agreement for each of the 11 statements about possible positive experiences associated in giving care to a family member with memory or health problems.
- Preparedness for Caregiving Scale
The Preparedness for Caregiving Scale is a five-item, self-rated scale that assesses a caregiver's perceived readiness to handle certain domains of caregiving (e.g., providing physical care and emotional support; setting up care; and dealing with the stress of caregiving). Respondents indicate on a scale of 0 (not at all prepared) to 4 (very well prepared) their preparedness for each of the items. A score is calculated by taking the mean of all of the responses provided. Higher scores indicate higher preparedness for caregiving.

A brief measure conducted over the phone to test semantic memory by presenting four target words and corresponding category cues. After an interference period (2-3 mins) participants recall as many words as they can without cues, and when words are not recalled freely, interviewers provide category cues. Scores are generated based on doubling the number of words retrieved during a "free recall" period, and adding that to the number of words retrieved during a "cued recall" period.

- Telephone Interview for Cognitive Status Modified (TICSM)
A screening test for cognitive impairment based on the original Telephone Interview for Cognitive Status (TICS), but differs in the word recall tasks and omits items that were difficult to verify over the telephone.

This tool can generate an individual score of the number of multimorbidities (sum of conditions), and the degree of multimorbidity (grading the number of chronic health problems per matrix item). The Multimorbidity Matrix can provide an overview of an individual patient's current clinical health problems, including past disease or injury that may still be impacting current health status.

For each condition, respondents indicate: whether or not they have the listed condition; whether or not they receive treatment for the condition (proxy for disease severity); whether or not the condition limits their activities (proxy for burden of condition). Respondents can also write-in up to three additional conditions and answer the three questions for each additional condition. A score is generated by adding up the responses to each of the questions for each condition listed.
