Brain scans may predict online therapy success for common mental health issues

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Meeting DSM-5 criteria for depression, social anxiety or insomnia. Diagnosis and measures of symptom burden and functional level are made through a structured interview, the Mini-International Neuropsychiatric Interview (M.I.N.I.) and self-assessments of symptoms. Healthy controls should not be relevant to psychiatric treatment nor meet criteria for any psychiatric condition according to the M.I.N.I. * Being able to read, write and speak Swedish in order to be able to read the treatment texts and be able to make phone calls. * Having basic computer skills to be able to complete surveys via the Internet and access the treatment platform. Exclusion Criteria: * Physical or mental illnesses who are either contraindicated for treatment (for example, bipolar disorder that can be exacerbated by treatment) or for other reasons need other treatments (e.g. severe depression, suicidal behavior, psychotic illnesses or extensive cognitive difficulties). * High alcohol consumption or other ongoing drug use. * Answering "yes" to any of the following questions will be excluded for participation: 1) "Have you or have you had any electrical / battery operated implants in your body? For example, a pacemaker, medication pump, neurostimulator, hearing implant, or other electrical / battery controlled implant?" 2) "Have you done any surgery on the abdomen, chest, heart or brain, eyes, ears? For example, vessel clips, or objects such as screws, heart valve, shunt or prosthesis?" 3) "Do you have or have you had any metallic object in your body?" 4) "If a woman, are you pregnant or breastfeeding?" 5) "Do you undergo dialysis or have kidney dysfunction?" Participants who answer yes to these follow-up questions will be interviewed more closely to determine if MRI security can be guaranteed and whether the MRI signal will have significant disruptions, for example due to dental scaffolding. 1) "If you have any abdominal, thoracic, heart or brain, eyes, ears? Do you have any inoperable object that has ferromagnetic properties?" The patient will be asked to consult his doctor about this. 2) "If you have a dental rack, what type of dental rack (fixed or removable, metal plates / rails or wire)"?
