Assessment

Primary outcomes

At Post point (i.e., end of intervention) and Follow-up point which is 3 months later of Post point: (1) Sheehan Disability Scale, (2) Generalized Anxiety Disorder-7, (3) Patient Health Questionnaire-9.

Key secondary outcomes

Classification of the percentage of subjects achieving functional and/or symptomatic resolution at the end of the intervention period (post) and 3 months later (follow-up):
(1) Recovery: Sheehan Disability Scale (SDS) scores below the remission criteria (<= 6) and Penn State Worry Questionnaire (PSWQ) scores below remission criteria (<= 47)
(2) Functional remission only: Sheehan Disability Scale score below the cutoff (<= 6)
(3) Symptomatic remission only (improvement): Percentage of person achieving symptomatic remission criteria and clinically significant change on the PSWQ (>= 7 points reduction and final score on PSWQ <= 47)

Ecological Momentary Assessment-social function items change between Baseline term (1 week before intervention start) to Post term (1 week later of the end of intervention term).
