Inclusion Criteria: * the care recipient has a physician diagnosis of TBI and AD/ADRD (i.e., those with a diagnosis of both TBI and progressive cognitive decline) * the caregiver self-identifies as someone who provides the most help/is most responsible for the person with TBI-AD/ADRD because of their cognitive impairments (or shares the role equally with another caregiver) * the caregiver indicates a willingness to participate in the TACSI evaluation * the caregiver is English speaking * the caregiver is 21 years of age or older * the caregiver is not currently participating in any other type of service that provides one-to-one psychosocial consultation or caregiver coaching (peer mentorship/support group participation/general counseling not specific to caregiving is not a deterrent to enrollment) at the discretion of the UMN research team * the caregiver resides in the US. Exclusion Criteria: * caregivers who have a new or worsening mental health condition and are not receiving ongoing treatment. When applicable, if caregivers have not remained on a stable psychotropic medications dosage, such as antidepressants, anxiolytics or anti-psychotics, for the prior three months they will be excluded.
