실험적: Dysphoric target
Participants will receive individualized connectome-guided accelerated iTBS at their dysphoric target. Participants will receive an accelerated iTBS treatment delivered with a MagVenture MagPro X100 system (MagVenture A/S, Denmark) equipped with a butterflu shaped MagVenture Cool-B65 A/P coil. The treatment course is comprised of 6 treatment sessions daily for 5 consecutive workdays for a total of 30 sessions. Each iTBS session is approximately 10 minutes (depth corrected Resting Motor Threshold of 90%, 60 cycles of 10 bursts of three pulses at 50Hz, repeated at 5Hz; 2s on and 8s off; 1800 puolses per session; with a 50-minute interval between sessions). All iTBS sessions will be performed by staff trained and credentialed in TMS according to Singapore College of Psychiatrists guidelines. |

Rank- Transformed Ratio of Beck Depression Inventory (BDI) to Beck Anxiety Inventory (BAI) change
기간: Baseline (before treatment), immediately after acute treatment (after 30 treatments over 1 week), and weekly during the 1-month follow-up period.
|
The primary outcome will be the rank-transformed ratio of BDI change to BAI change (e.g.
A patient has a 50% reduction in BDI and a 25% reduction in BAI, giving a BDI:BAI ratio of 50% ÷ 25% = 2.0.
Another patient has a 40% reduction in BDI and a 25% reduction in BAI, giving a BDI:BAI ratio of 40% ÷ 25% = 1.6.
Higher ratios indicate a relatively greater improvement in depression compared with anxiety within each patient.
This ratio is then ranked across all patients.).

Inventory of Depression and Anxiety Symptoms-II (IDAS-II)
기간: Baseline (before treatment), immediately after acute treatment (after 30 treatments over 1 week), and weekly during the 1-month follow-up period.
|
IDAS-II is an ordinal self-report scale measuring depression, anxiety, and bipolar symtpoms ranging from 99-495.
Higher scores mean worse outcome.
|
Baseline (before treatment), immediately after acute treatment (after 30 treatments over 1 week), and weekly during the 1-month follow-up period.

|
Penn State Worry Questionnaire (PSWQ)
기간: Baseline (before treatment), immediately after acute treatment (after 30 treatments over 1 week), and weekly during the 1-month follow-up period.
|
PSWQ is an ordinal self-report scale measuring pathological worry ranging from 16-80.
Scores depend on whether the item is worded positively or negatively.

Interaction between TMS target and change in BDI and BAI
기간: Baseline (before treatment), immediately after acute treatment (after 30 treatments over 1 week), and weekly during the 1-month follow-up period.
|
The investigators will test interactions between TMS Target and change in BDI and BAI (including baseline and weekly outcomes over one month) separately using repeated measures linear mixed effects models.

TMS induced changes in resting-fMRI functional connectivity
기간: Baseline (before treatment), immediately after acute treatment (after 30 treatments over 1 week), and weekly during the 1-month follow-up period.
|
The investigators will perform additional exploratory post-hoc analyses by analysing brain imaging changes before and after TMS treatment.

Passive physiological metrics
기간: Baseline (before treatment), immediately after acute treatment (after 30 treatments over 1 week), and weekly during the 1-month follow-up period.
|
The investigators will also perform additional exploratory post-hoc analyses by analysing passive physiological data collected using an Oura ring throughout the study duration.
