Indigenous Peoples Survey (IPS) |
The IPS is a clinician administered instrument for collective group trauma, lifetime trauma exposure, tribal cultural identity values and practices, religiosity/spirituality and the experiencing of racism and discrimination on mental health symptoms and associated outcomes. The IPS is an investigator constructed measure grounded in prior work on HTUG. The IPS includes questions about tribal cultural identity, values and practices; health and mental health; grief, trauma exposure and symptoms; and experiences of racism and discrimination. It includes investigator constructed questions and standardized measures, with the intent that AI mental health clinics could use the IPS to conduct more comprehensive assessments framed in a culturally resonant structure. |

Changes in Hamilton Depression Scale from Baseline |
Scale commonly used in IPT studies to assess depressive symptoms and track change over time. The Ham -D24 (and other shorter versions) is a commonly used clinician-administered depression assessment scale. This HAM-D24 is a 24 item version that incorporates three new items that assess helplessness, hopelessness, and worthlessness. The measure is commonly used to rate the severity of, and change in, a patient's major depression. It includes 24 items rated on a scale from 0-2, 0-3, or 0-4, with a total score computed ranging from 0-75. An earlier version of the Hamilton Depression Rating Scale the HAM-D17 has the following psychometric properties: Cronbach's alphas have been found to range from 0.46 to 0.97; inter-rater reliability, Pearson's r ranged from 0.82 to 0.98; and the intraclass r ranged from 0.46 to 0.99. The HAM-D24 is believed to have similar psychometric properties. |

Changes in the PCL PTSD Checklist |
The PCL is a 17-item self-report measure of the 17 DSM-IV symptoms of PTSD. The PCL is used to screening individuals for PTSD, diagnosing PTSD, and monitoring symptom change during and after treatment. A total symptom severity score (range = 17-85) can be obtained by summing the scores from each of the 17 items. The PCL has good internal consistency, with a Cronbach's alpha of .86. |

Changes on the Historical Losses and Historical Losses Associated Symptoms Scales (HLS/HLAS) |
Historical Losses and Historical Losses Associated Symptoms Scales - The items selected for HLS were determined by a series of focus groups conducted with elders in two tribes in the upper Midwest to identify the kinds of losses associated with historical trauma and the types of emotions felt when thinking about those losses. The HLAS asks how often the respondent feels each of 12 symptoms (e.g. anger, sadness, like the loss is happening again) when they think about the losses. The scale has good internal reliability, with a Cronbach's alpha of .89. |

Changes in the Inventory of Complicated Grief (ICG) |
The ICG assesses indicators of pathological grief, such as anger, disbelief, and hallucinations. It consists of 19 first-person statements concerning the immediate bereavement-related thoughts and behaviors of the client, with 5 response options ranging from "Never" to "Always." The ICG's internal consistency is good, with a Cronbach's alpha of .94. The test-retest reliability has been found to be .80. The scale has a well validated clinical cut point, with individuals scoring over 25 considered at risk for requiring clinical care. |

Inventory of Interpersonal Problems (IIP) |
The IIP is a self-report measure that identifies an individual's most salient interpersonal difficulties. There are two forms: The IIP-64 contains 64 statements describing common interpersonal problems. Scales include: Domineering/ Controlling, Vindictive/Self-Centered, Cold/Distant, Socially Inhibited, Nonassertive, Overly Accommodating, Self-Sacrificing, and Intrusive/Needy. Respondents rate how distressed they have been by each problem on a scale from 0 (not at all) to 4 (extremely). The IIP scales have adequate internal consistency and test-retest reliability. |

Medication Adherence Questionnaire |
this questionnaire was developed for implementation with research participants to assist in tracking the compliance with any current medication management that the participant is currently engaging in with their primary health care or behavioral health care provider. This is to see if the current medications are appropriate and helpful with depressive symptoms being experienced by the participant prior to entering into the study and during their participation in the study. This is part of Treatment as Usual to which research participants are entitled and is part of good clinical care. |

Group Environment Scale |
Developed by Moos, Insel, and Humphrey this measure is to assess group climate and comfort level of the study participants to openly discuss issues related to the target symptoms of depression in group. Clinical group facilitators/staff at each study site will complete the observational measure. |
