To be eligible, participants must be * able to comprehend and sign the informed consent form * able to complete the structured interviews and self-report assessments * willing to be contacted for follow-up assessments For newly enrolled participants: * given that the investigators have already recruited a large sample of veterans who are reporting relatively little functional impairment, the investigators will require newly enrolled participants to self-report global functional impairment on the WHODAS 2.0 12-item self-report version equivalent to a mean item score of 1.0. * Although the investigators anticipate being able to meet the recruitment goals, should recruitment prove more challenging than expected, the investigators will remove this inclusion criterion * deemed stable on psychotropic medications (defined as 3 months on a selective serotonin reuptake inhibitor or monoamine oxidase inhibitor; \>1 month on an anxiolytic or beta-blocker; \>1 month medication discontinuation or "wash out" for all medications) at the time of the BL assessment * deemed stable in psychotherapy (3 months stabilization for psychotherapy and 1-month psychotherapy wash-out) at the time of the BL assessment * These latter two criteria are instated to ensure that symptoms assessed during the baseline assessment are due to any underlying psychiatric condition and not due to the effects of starting or stopping medications and/or psychotherapy. * Changes in treatment will be permissible during the current study, as this reflects real-world practice * All changes in medications will be monitored over time, and appropriately covaried, as treatment can have important effects on functioning over time * Individuals will be eligible to participate with current and lifetime psychiatric diagnoses, with the exception of: * schizophrenia * schizophreniform disorder * schizoaffective disorder * delusional disorder * unspecified schizophrenia spectrum/other psychotic disorder, and bipolar disorder Additional inclusion criteria specific to the SCD treatment study are: * Veterans will have a global disability (mean item) score on the WHODAS 2.0 of 1.0, which is 1 SD above the mean of the large non-psychiatric sample …
